Mathematics is still considered a complex and tedious subject in school. The use of Augmented Reality (AR) technology in mathematics learning for junior high school students offers an innovative approach to improving understanding of abstract concepts. This study aims to develop learning media for cube material in junior high schools using Augmented Reality (AR) technology. The development method uses the Research and Development (R&D) model with a 4D model (Define, Design, Develop, and Disseminate). Data was collected through questionnaires and interviews and analyzed quantitatively and qualitatively. The validation process for the developed product was conducted by material and language experts, as well as media experts. Subsequently, small-scale and large-scale product trials were conducted with teachers and students at junior high schools in Jakarta. The test results showed an average overall rating of 92.46%. This means the AR product developed for cube material meets the criteria for being highly suitable as an alternative learning resource for junior high schools. The use of AR media can visualize three-dimensional geometric objects, making it easier for students to understand spatial and shape concepts.

Integration Of Deep Learning Approach In Developing Innovative Teaching Behavior Of Elementary School Teachers

2026-02-21T12:18:28+07:00

This study aims to explore the integration of deep learning approaches in developing innovative teaching behaviors among elementary school teachers. The background of research stems from the need to improve the quality of learning through adaptive, creative, and technology-based teaching strategies. The research method used was an exploratory qualitative approach through interviews, observations, and documentation studies. The results indicate that the implementation of deep learning integration has not been optimally implemented. This is due to limited teacher competency in understanding the concept of deep learning, minimal technological infrastructure support, resistance to change, and suboptimal support from school principals. Other obstacles that arise are limited infrastructure and teacher resistance to changes in learning patterns. This study recommends the need for ongoing training programs, school policy support, and intensive mentoring so that deep learning integration can be effective in developing innovative teaching behaviors among teachers.

The Effect of Citrid Acid on Isolation of Kimpul Tumber Starch (Xanthosoma Sagittifolium Schot)

2026-02-21T12:23:24+07:00

Starch is a natural polymer that can be digested to produce energy for humans and is abundantly found in plants. Starch granules consist of two main components, namely amylose and amylopectin, both of which serve as storage forms of complex carbohydrates in plants. Carbohydrates are a primary source of energy; in addition, they can be used as basic materials for various industrial applications, such as food and bioplastics. Kimpul tubers are a type of local food crop with significant potential as an alternative food source. This study aimed to identify the effect of citric acid on the isolation of kimpul starch in terms of moisture content, carbohydrate content, fat content, protein content, fiber content, and ash content. The independent variable in this study was the concentration of citric acid (2.5%, 5%, and 7.5%), arranged using a factorial Completely Randomized Design (CRD). The results showed that soaking in a citric acid solution produced starch with moisture content ranging from 6.80–11.38%, carbohydrate content of 79.29–82.99%, fat content of 1.21–2.25%, protein content of 4.27–4.60%, fiber content of 2.70–2.87%, and ash content of 0.96–1.03%.

Implementation of Adaptable Network Monitoring Using MRTG

2026-02-21T12:30:01+07:00

Having optimal network traffic management is a key element in building a reliable network infrastructure, especially for organizations that rely on connectivity to carry out their business activities. Various software is available, such as Solarwinds or PRTG, which provide full monitoring functionality, easy to use display, sophisticated analysis and advanced reporting capabilities. However, high costs are an obstacle for some organizations to do so. In these circumstances, the Multi-Router Traffic Guard (MRTG) provides a more affordable and effective solution based on open-source network monitoring needs. MRTG is a software package that provides an abstraction view of network traffic. Using the Simple Network Management Protocol (SNMP), MRTG collects data from network devices such as routers and switches and can monitor real-time network performance. Through SNMP, you can automatically get information about network usage, device status, and other statistics about the network. The purpose of this study is to examine the use of MRTG and assess its performance as an open-source solution for monitoring network traffic. The study was performed in stages, starting with installing and configuring MRTG and SNMP on Linux, then collecting SNMP network traffic data, and presenting the results in a graphical representation. The final stage is to assess the accuracy of the resulting data and the overall performance of the system. The result showed that MRTG can capture traffic on a network and help administrators detect problems more quickly and respond more effectively.

Analysis of Language Politeness in Arif Muhammad's Youtube Video “Beti Pelakunya”

2026-02-21T12:32:18+07:00

This study aims to examine the forms of politeness in language used in Arif Muhammad's YouTube video entitled "Beti Pelakunya" by applying Leech's politeness principle theory. Using a qualitative descriptive method, the required data was taken from the transcription of the characters' speech in the video, which was then analysed through six maxims of politeness: wisdom, generosity, praise, humility, agreement, and empathy. The findings of this study indicate that the characters, especially Beti and Sutrisno, often employ politeness strategies to maintain harmonious communication, such as apologising, providing clarification, and giving compliments. However, some utterances also appear to violate the principles of politeness, especially from the characters Min and Along, who often express criticism openly or display selfish attitudes. Overall, the interactions that occurred indicate that the principles of politeness can still be applied in digital media, even in the context of entertainment and jokes. Polite language in these videos reflects the social and cultural values of society and emphasises the importance of communication ethics in the digital age.

Keywords: pragmatics, politeness, video.

Quantifying Paper Waste Generation to Support Sustainable Waste Management at the Institut Teknologi Sumatera

2026-02-21T12:42:53+07:00

Paper waste generation in higher education institutions represents a significant environmental concern due to its considerable volume and resource potential. At the Sumatera Institute of Technology, paper waste management has not been fully optimized, and data on paper waste generation are still limited. Therefore, this study aims to analyze paper waste generation at the Institut Teknologi Sumatera. The method used to calculate paper waste generation in this study was the waste sampling method based on SNI 3964-2025. Waste sampling was conducted for eight consecutive days in four administrative buildings at the Institut Teknologi Sumatera. The results indicated a total paper waste generation of 11.7 kg/day, with the highest contribution originating from the Student Affairs and Finance Office building (3.9 kg/day). The findings demonstrate that paper waste generation is influenced not only by population size but also by the characteristics of administrative activities, document processing intensity, and institutional work systems. This study provides essential baseline data to support the planning of paper waste reduction, reuse, and recycling programs, contributing to the development of sustainable waste management strategies in higher education institutions.

Domestic Waste Disposal Behavior and Its Socio-Ecological Aftermath

2026-02-21T12:45:57+07:00

Domestic waste pollution in the Way Kuripan River has triggered serious ecological degradation. This study aims to analyze the physicochemical characteristics of the water and the socio-environmental impacts on the riverbank community. Using a descriptive quantitative approach, this study integrates water quality data with primary data from 98 respondents selected via purposive sampling. The results reveal an ecological decoupling phenomenon: the river's physical stability is maintained with low TSS (18 mg/L), yet it suffers from severe hypoxic pressure (DO 3 mg/L) and high organic load COD (25 mg/L), failing to meet Class I Quality Standards. Low Fecal Coliform levels (14 MPN/100mL) confirm the dominance of grey water pollutants. Socially, a critical knowledge-behavior gap was found, despite high literacy, 77% of residents discharge waste directly into the river. Spearman Rank correlation tests showed no significant relationship (p=0,120) between risk perception and behavior, confirming that pollution is driven by structural barriers, specifically the lack of sanitation infrastructure reported by 82% of respondents, rather than low awareness. This condition causes social displacement and a high prevalence of health complaints (94%).

Saying Less, Meaning More: Conversational Implicature in Langsa Market Interactions

2026-02-21T12:50:57+07:00

Conversational implicature plays a central role in everyday interactions, particularly in informal settings where meaning is negotiated through context, social relations, and interactional goals. Traditional markets provide a rich site for examining how speakers convey meaning indirectly while managing negotiation, politeness, and face. This study explores conversational implicature in buyer–seller interactions at Langsa traditional market using an interactional pragmatics perspective. Rather than treating implicature as a fixed rule-based phenomenon, the study views meaning as something collaboratively constructed through naturally occurring talk. Data were collected through audio-recorded market interactions between buyers and sellers during routine transactions and negotiations. Selected interactional excerpts were transcribed and analyzed qualitatively to examine how indirectness and implied meanings emerge, are interpreted, and are responded to in real-time interaction. The findings show that implicature in Langsa market interactions is closely tied to negotiation strategies, social positioning, and situational constraints such as price sensitivity and relational familiarity. Indirect expressions are frequently used to soften requests, signal dissatisfaction, suggest alternative prices, or maintain social harmony without explicit confrontation. These implicatures are not interpreted in isolation but are co-constructed through turn-taking, shared local knowledge, and immediate contextual cues. This study contributes to interactional pragmatics by highlighting how conversational implicature functions as a practical communicative resource in marketplace discourse.

Keywords: conversational implicature; interactional pragmatics; Langsa market; marketplace discourse; indirectness.

Analyzing the Interface Design of VOCAYO: A Qualitative Case Study

2026-02-26T11:00:28+07:00

Digital learning applications for English language education have increasingly emphasized not only content quality but also interface design, as interface plays a crucial role in shaping learners’ engagement and learning experience. VOCAYO is a contextual English learning application developed to introduce English vocabulary related to local tourism contexts. While previous studies often focus on learning outcomes or technological effectiveness, limited attention has been given to how interface design supports contextual learning in locally grounded digital applications. This study aims to analyze the interface design of VOCAYO through a qualitative case study approach. The analysis focuses on visual layout, navigation structure, content presentation, and contextual relevance of the interface elements. Data were collected through systematic interface observation, and reflective analysis based on established principles of educational interface design. The findings indicate that VOCAYO’s interface emphasizes simplicity, cultural familiarity, and contextual clarity, which contribute to user-friendly navigation and reduced cognitive load. Visual consistency, intuitive icons, and localized vocabulary presentation support learners’ interaction with the application without overwhelming them with technical complexity. However, the analysis also identifies areas for improvement, particularly in interaction feedback and visual hierarchy enhancement. This study highlights the importance of interface design as a pedagogical component rather than a purely aesthetic element. The findings provide practical insights for developers and educators involved in designing contextual digital learning applications, especially those integrating local knowledge and sustainable education perspectives.

Integrating Artificial Intelligence and Local Wisdom in Mental Health Services: A Literature Review on the Synergistic Role of AI and Psychologists in Indonesia

2026-02-21T14:08:59+07:00

Unequal access to psychological services in Indonesia has heightened the urgency for more inclusive mental health support. This study aims to examine the role of artificial intelligence (AI) in supporting psychologists and counselors and to analyze how the integration of local wisdom enhances the effectiveness of technology-based mental health services. This study employs is a literature review of publications from the past ten years that discuss the use of AI in mental health, the role of professional psychological practice, and Indonesian cultural values such as gotong royong and pantun petuah. The findings indicate that AI can be effective in providing psychoeducation, early symptom screening, and basic emotional support, while complex clinical and relational processes still require human presence and emotional sensitivity. The literature further suggests that AI designed with cultural adaptation is more acceptable and increases user trust and comfort. The implications of this study emphasize the importance of developing a culturally responsive synergy in which AI extends service reach and accessibility, while psychologists and counselors maintain the depth, meaning, and professional quality of psychological care. This approach supports the development of mental health services that are not only technologically innovative but also culturally relevant and socially grounded within the Indonesian context.

Challenges in Developing Mathematical Literacy among Junior High School Students in Aceh, Indonesia

2026-02-21T14:12:05+07:00

Mathematical literacy and numeracy are essential competencies that enable students to solve real-world problems and apply mathematical knowledge meaningfully. Nevertheless, evidence from various assessments indicates that junior high school students in Indonesia still exhibit low levels of mathematical literacy and numeracy. This study aims to explore the underlying causes of these difficulties based on in-depth interviews with teachers and students. The research employed a qualitative descriptive approach and was conducted in three regions of Aceh, Indonesia. Data were collected through semi-structured interviews with junior high school mathematics teachers and students, focusing on learning experiences, instructional practices, and students’ engagement with contextual mathematical problems. The findings reveal several key factors contributing to students’ low mathematical literacy and numeracy. First, students are not familiar with PISA-type problems that require contextual interpretation, reasoning, and problem-solving skills. Second, mathematics instruction tends to emphasize procedural learning and routine exercises rather than conceptual understanding and real-life applications. Third, learning activities provide limited exposure to contextual and meaningful problems that support literacy and numeracy development. These findings indicate that current instructional practices have not sufficiently supported the development of students’ mathematical literacy and numeracy skills. The study underscores the importance of designing learning approaches that promote contextual problem solving and higher-order thinking.

Keywords: mathematical literacy, numeracy, PISA-type problems, procedural learning

The Impact of Flash Floods and Landslides in Sumatra on the Income of MSMEs in Aceh

2026-02-21T14:15:36+07:00

This study aims to examine the impact of flash floods and landslides in Sumatra on the income of Micro, Small, and Medium Enterprises (MSMEs) in Aceh, using a literature review. Flash floods and landslides can significantly reduce business income, especially in the agricultural and MSME sectors, through land damage, asset loss, and decreased productivity. Studies in similar regions show that household and business income can drop dramatically during and after a disaster, by as much as 80% compared to normal conditions. In addition, MSMEs face further challenges, including higher operating costs due to limited electricity supply, infrastructure damage, and restricted access to raw materials and markets. Factors such as income diversification, educational levels, and membership in social organizations can affect SMEs' vulnerability and their ability to adapt to disasters. The results of this review emphasize the importance of mitigation efforts, improving disaster literacy, and government policy support and access to financing to strengthen the resilience of SMEs in Aceh to the risks of flash floods and landslides.

Pre-Trial Detention and Prison Overcrowding in Madagascar: A Comparative Glimpse with Indonesia

2026-02-21T14:19:45+07:00

This article examines how pre-trial detention, judicial delay and the limited use of non-custodial measures contribute to structural prison overcrowding in Madagascar and Indonesia. It asks three questions: (1) What do recent prison statistics show about the scale and main drivers of overcrowding in both countries? (2) How do their constitutional and legislative frameworks regulate pre-trial detention, “reasonable time” of trial and alternatives to custody? and (3) To what extent does the combined reading of law and data comply with constitutional and international standards on liberty and humane treatment? Methodologically, the study adopts a normative–juridical and comparative design, combining doctrinal analysis of constitutions, codes of criminal procedure, prison and juvenile justice laws with secondary quantitative data from the World Prison Brief on prison population, occupancy and pre-trial detention from the early 2000s to 2025. The findings show that Madagascar’s system operates at almost three times its official capacity, with pre-trial detainees representing around half of all prisoners, while Indonesia, although less overcrowded in relative terms, still functions at nearly double capacity and holds a substantial remand population. In both jurisdictions, legal frameworks formally present pre-trial detention as exceptional and recognise a wide catalogue of non-custodial measures, yet these safeguards are only partially effective in practice, especially for women and children. The article concludes that the central problem is the gap between law “on the books” and law “in action” and argues for targeted reforms to reduce unnecessary remand, strengthen judicial oversight and mainstream non-custodial sanctions in line with ICCPR standards and Sustainable Development Goal 16.

Keywords: pre-trial detention, prison overcrowding, Madagascar, Indonesia, comparative study

The Effectiveness of Snort in DDoS Attack Scenarios

2026-02-21T14:37:53+07:00

Secure communication in the digital era has become important, while on the other side, the attackers are consistently moving into more sophisticated ways to acquisition their target. DDoS was one of the common techniques used with the aim to overwhelm and make their target fail to function. To detect and limit this threat, many organizations have begun to employ various solutions. However, it was discovered that several solutions are ineffective while others require high cost for the implementation, and this has become a challenge for medium to low-sized organizations to meet their business strategy. For that, in this study we aim to introduce Snort as an open source solution for the network detection and prevention system to determine how it undertakes and performs analysis especially in terms of accuracy and speed in relation to DDoS attacks. This study will involve a few steps: first, to establish the simulation environment; secondly, to perform the simulation with a DDoS attack to allow Snort to capture the traffic and respond according to the pre-established rules; and finally, to measure and evaluate the result. Snort as an open-source product, in nature allows the public to contribute, and that becomes the advantage compared with other commercial products especially in detecting anomalies. This will help the administrators to react more quickly by having an accurate information with an earlier warning system. Additionally, Snort is affordable, making it good choice for the organization.

Effects of Snail Shell Waste on Compressive Strength of Concrete with Partial Cement and Fine Aggregate Replacement

2026-02-21T14:43:51+07:00

The concrete industry is under increasing pressure to reduce cement consumption and natural aggregate exploitation to enhance environmental sustainability. In Leupung District, Aceh Besar Regency, Indonesia, the consumption of black snail as a traditional local food, rooted in coastal community local wisdom, generates significant shell waste that remains largely underutilized. While previous studies have extensively examined other biogenic wastes, the use of snail shell waste (SSW) as a partial replacement for cement and fine aggregate has received limited attention. This study proposes an innovative integration of local wisdom with modern concrete technology by employing SSW as a dual substitution material. The objective was to evaluate the compressive strength performance of concrete incorporating snail shell waste at replacement levels of 0%, 5%, 10%, and 15%, targeting a design strength of 17 MPa. Compressive strength tests were conducted in accordance with ASTM and ACI standards. The results showed compressive strengths of 21.98 MPa for the control mix and 19.23 MPa, 17.86 MPa, and 17.53 MPa for the 5%, 10%, and 15% mixtures, respectively. Regression analysis revealed a strong negative linear relationship (y = −0.2948x + 21.361; R² = 0.8808) between replacement level and compressive strength. Although strength decreased with increasing substitution, all mixtures met the target concrete strength, indicating that SSW derived from local wisdom practices is suitable for application in non-structural concrete and contributes to sustainable waste utilization.

Vegetation Analysis Using the Square Transect Method in the Bodogol Nature Conservation Education Center

2026-02-21T14:47:14+07:00

Bodogol Nature Conservation Education Center is part of Gunung Gede Pangrango National Park and represents lower montane forest vegetation that is still relatively well preserved. This study aimed to describe the structure and composition of the plant community and relate it to soil edaphic conditions. A descriptive-quantitative approach was applied using the square transect method with random sampling on three transects equipped with nested plots of 20 × 20 m, 10 × 10 m, 5 × 5 m, and 2 × 2 m. All plant species found in the plots were recorded, and the number of individuals per species was used to calculate density, frequency, dominance, the Importance Value Index (IVI), as well as the Shannon-Wiener diversity index (H’), evenness (E), and species richness (R). A total of 36 species were recorded with a few dominant species, particularly Schima wallichii and Vernonia amygdalina, while most other species showed low IVI values. The H’, E, and R values indicate low diversity, evenness, and species richness, with a community dominated by a small number of adaptive species. Edaphic conditions characterized by sandy soils with near-neutral pH, relatively stable soil temperature, and decreasing soil moisture with depth help shape this dominance pattern. These findings provide baseline information on community structure and edaphic conditions to support vegetation management and conservation planning in the Bodogol area.

From Local to Neutral: Monophthongization of /eu/ and /oe/ in Barat–Selatan Aceh Accent

2026-02-21T14:52:52+07:00

Accent erosion has become a noticeable phenomenon in many regional speech communities, particularly in areas experiencing increased linguistic contact and social mobility. In the Barat–Selatan Aceh (BARSELA) region, local accent features are gradually shifting toward more neutral forms, one of which is reflected in vowel change. This study investigates accent erosion through the process of monophthongization of the diphthongs /eu/ and /oe/ as a qualitative case study of BARSELA speakers. The study focuses on how these diphthongs are realized in contemporary speech and how their changing pronunciation signals broader accentual change. Data were drawn from naturally occurring spoken interactions and selected elicited speech samples produced by speakers in the region. Qualitative phonological analysis reveals consistent patterns of monophthongization, where /eu/ and /oe/ are frequently realized as simpler vowel forms in everyday communication. These shifts are especially evident in informal contexts and among speakers with higher exposure to external linguistic influences. The findings suggest that monophthongization in BARSELA speech is not random, but represents a systematic phonological process associated with accent leveling and adaptation toward more widely intelligible speech forms. By focusing on specific vowel changes, this study contributes to sociophonetic and sociolinguistic discussions on accent erosion, highlighting how subtle vowel shifts can function as salient indicators of ongoing accent change in regional speech communities.

The Role of Women Based on Local Wisdom in Improving Family Welfare through MSME Empowerment in Aceh Besar Regency

2026-02-21T14:55:43+07:00

Economic empowerment activities for women have contributed to the achievement of gender equality at the family and village levels. Micro, Small, and Medium Enterprises (MSMEs) are businesses classified based on their scale of operation, which is determined by factors such as asset value, annual revenue, and number of employees. MSMEs play a crucial role in economic development by creating employment opportunities, promoting entrepreneurship, and supporting local and national economies. Women-MSME actors are not yet aware of the importance of Islamic values in business. The researchers went directly to informants who were women MSME entrepreneurs in Aceh Besar Regency. However, many MSMEs led by women have survived and continue to operate because they are able to adapt to online marketing, changing the type of business, and learning better Islamic financial management. The objectives of this study are to (a) identify the empowerment of women MSME actors; (b) test the concept of women MSME actors' empowerment based on Islamic values and local wisdom in realizing family welfare. This study uses a structured interview as the instruments in collecting the data. This method was used to record the experiences of rural MSMEs led by women. The results of the study show that highly educated rural women contribute more to increasing family income and reducing poverty, while women with low education contribute less to their families and poverty reduction.

Keywords: MSMEs, Women MSMEs, Family welfare.

Application of Coal Fly Ash as Adsorbent for Removing Lead (Pb) Metal

2026-02-21T15:02:40+07:00

Coal fly ash (CFA), a major byproduct of coal combustion, poses significant environmental challenges due to its hazardous constituents, including heavy metals. This study explores the potential of CFA sourced from PT PLN Nusantara Power UPK Nagan Raya as a low-cost adsorbent for Pb removal from aqueous solutions. The research investigates the influence of adsorbent dosage and stirring time on adsorption efficiency and capacity, aiming to optimize conditions for practical application in wastewater treatment. Characterization of CFA revealed a composition dominated by silica and alumina, with crystalline phases such as quartz and mullite, which provide active sites for adsorption. Batch experiments were conducted at varying CFA doses (2–8 g) and contact times (30–90 minutes), with pH fluctuations monitored throughout the process. Results indicate that adsorption efficiency increases with higher adsorbent dosage and extended stirring time, achieving a maximum Pb removal of 99.684% at 8 g and 90 minutes. Conversely, adsorption capacity (mg/g) was highest at lower doses, peaking at 0.945 mg/g for 2 g at 90 minutes, reflecting the trade-off between efficiency and capacity due to particle agglomeration and site saturation at higher doses. The findings confirm CFA’s dual mechanism of Pb removal through surface complexation and precipitation, influenced by pH and mineral composition. This study demonstrates that CFA can serve as an effective, sustainable adsorbent for heavy-metal remediation, offering a circular-economy solution for coal combustion residues. Future work should address regeneration strategies and safe disposal of spent adsorbent to prevent secondary contamination.

Effect of Binder Ratio and Carbonization Temperature on the Calorific and Mechanical Characteristics of Biocoke from Oil Palm Fronds

2026-02-24T09:25:52+07:00

This study investigates the production and characterization of biocoke derived from oil palm fronds, using carbonized durian seed powder as a binder under varied carbonization temperatures and binder ratios. The experiment was done in laboratory‑scale to determine the optimal process conditions. Oil palm fronds were carbonized at temperatures of 400°C, 450°C, and 500°C, then mixed with durian seeds at ratios of 5%, 10%, and 15%. The mixture was molded and compacted at temperatures of 150–200°C under a pressure of 10–20 MPa. Data biocoke produced were assessed based on moisture content, ash content, calorific value, and mechanical strength. Result showed that by increasing carbonization temperature from 400 °C to 500 °C, could enhanced the fixed carbon, reduced ash content, and improved calorific value of biocoke. By adjusting the binder ratio from 5% to 15% increased water content and calorific value. Meanwhile, the excessive binder ratio (15%) lowered mechanical strength, likely due to higher residual moisture. The best characteristics energy performance and mechanical integrity was achieved at 500 °C with a 10% binder ratio. In conclusion, oil palm fronds waste and durian seeds can be processed into an environmentally friendly and sustainable biocokes. These findings demonstrate a practical pathway to valorise agricultural biomass residues and locally available biogenic binders into biocokes serves as a sustainable, lower-CO2, and coal-reducing alternative to traditional coke in thermal combustions.

The Effect of Mudharabah Financing on The Welfare of Youth-Owned MSMES in Aceh Province

2026-02-24T09:29:32+07:00

Although Aceh Province has formally implemented an Islamic financial system, the utilization of mudharabah financing by youth-owned MSMEs remains suboptimal and shows considerable regional variation. This condition raises an empirical question regarding the extent to which mudharabah financing actually affects the welfare of youth MSME actors. This study aims to analyze the effect of mudharabah financing on the welfare level of youth-owned MSMEs in Aceh Province. The research employs a quantitative approach involving 50 youth MSME respondents distributed across Banda Aceh, Aceh Besar, Lhokseumawe, Aceh Barat, and Subulussalam. Data were collected through structured questionnaires and analyzed using descriptive statistics and simple linear regression. The results indicate that the level of mudharabah financing utilization falls within the low to moderate category, with substantial disparities in access across regions. Regression analysis reveals that mudharabah financing has a positive and significant effect on youth welfare, with a coefficient of determination of 41.2 percent. These findings confirm that limited access to mudharabah financing directly contributes to slower improvements in income and business stability among youth entrepreneurs. Therefore, strengthening access to and utilization of mudharabah financing is a key factor in enhancing the welfare of youth-owned MSMEs in Aceh.

Pidie Jaya Regency is one of the disaster-prone areas in Aceh Province, Indonesia, facing complex challenges in disaster risk management, including planning and budgeting consistency, institutional capacity, and community preparedness. This study aims to analyze the implementation of integrated disaster management governance in supporting regional resilience in Pidie Jaya Regency. A qualitative descriptive approach with a case study method was employed, utilizing policy document analysis, data from the Indonesian Disaster Risk Index (IRBI) and the Regional Resilience Index (IKD), as well as interviews with relevant stakeholders. The findings indicate that the integration of disaster management into regional development planning, budgeting, and cross-sectoral programs contributes significantly to enhancing regional resilience. This is evidenced by a decline in IRBI values and an improvement in IKD scores during the observation period. Integrated governance strengthens inter-institutional coordination, enhances institutional capacity, and increases community involvement in disaster risk reduction. This study confirms that strengthening integrated disaster management governance is a key determinant in achieving sustainable regional resilience, particularly in disaster-prone regions.
