The Trans-Sulawesi National Road section Majene-Mamuju (segment 010–009) is a vital land transportation artery supporting the mobility and economy of over 475,000 people. However, its geographical profile, narrow coastal corridors adjacent to steep hills and active fault lines, exposes it to severe multi-hazard threats. This study establishes a fixed infrastructure inventory of 94.7 km of national road and 79 critical bridge nodes to assess susceptibility to earthquakes, tsunamis, coastal abrasion, and landslides. Spatial analysis derived from sub-district data tables reveals that earthquakes are the most pervasive threat, impacting 90.69 km (95.8%) of the road and 65 bridges (82.3% of the inventory). Tsunami susceptibility represents the second most significant hazard, threatening 56.71 km (59.9%) of the network and 51 bridges (64.6%). Coastal abrasion affects 25.20 km (26.6%) of the road and 47 bridges (59.5%). Landslides, while localized, present a high-intensity risk to 5.66 km (6.0%) of the road and 6 bridges (7.6%). The Sendana, Tammeroddo Sendana, and Tubo Sendana sub-districts emerge as the most critical multi-hazard zones, with composite indices ranging from 2.57 to 2.82. While Ulumanda exhibits a high landslide susceptibility ratio (13.0%), Sendana represents the primary operational threat with 1.83 km of exposed road, nearly double the absolute physical impact found in Ulumanda. These findings provide a standardized scientific basis for prioritizing structural mitigation at critical bridge nodes to prevent total network severance during cascading disaster events DOI: https://doi.org/10.51557/yhjjy774

This article critically examines the normative boundaries governing judicial enforcement in civil procedure, focusing on the locus of enforcement authority in the operative part (dicta) of civil judgments. The study investigates the extent to which interpretative reliance on judicial reasoning (legal grounds) is permissible within enforcement processes without expanding the scope of the operative command. Employing a doctrinal legal methodology, this research analyzes statutory texts, principles of legal certainty, and contemporary debates in enforcement law. Findings illustrate that execution authority fundamentally attaches to the operative part of the judgment, while interpretative use of judicial reasoning should be strictly limited to clarifying ambiguous orders without introducing additional coercive measures. This position reinforces legal certainty and due process, especially in cases involving property execution and third party rights. The article contributes to the ongoing discourse on the rule of law and enforcement discretion by outlining a principled framework that respects enforcement constraints within civil procedure.

This study aimed to explore population and condition data on the Sulawesi Water Rat (Waiomys mamasae) from an ethnozoological perspective in five buffer villages surrounding Gandang Dewata National Park. Using a cluster sampling technique, 66 respondents from various professions with direct interaction with river ecosystems were selected, including hunters, farmers, and other individuals frequently active in river areas. Data were collected through questionnaire-based interviews to obtain information regarding the frequency of sightings of this species and its utilization in local communities. The results showed that 50% of respondents had directly observed the Sulawesi Water Rat, while the rest had never encountered it. In terms of utilization, local communities use this species as a protective talisman to prevent house fires, as traditional medicine, and as a source of food. Several local beliefs also describe unique abilities of this species, such as the capacity to walk on water or remain submerged for extended periods. The age distribution of respondents was dominated by individuals aged 35–48 years (32%), followed by other age groups. This study provides important insights into local knowledge and the relationship between communities and W. mamasae, which can serve as an important basis for conservation efforts and ecosystem management in the buffer areas of Gandang Dewata National Park

Despite growing emphasis on active and multimodal learning in EFL contexts, maintaining learner engagement in reading classes remains challenging. This sequential explanatory mixed-methods study examined how video-based group presentations influence reading engagement among Indonesian EFL learners. Ninety-nine third-semester students from Universitas Sulawesi Barat completed a 5-point Likert scale questionnaire measuring nine engagement dimensions derived from student engagement theory (behavioral, cognitive, affective), while 37 representative participants provided reflective journals for qualitative analysis. Findings revealed a mean engagement score of 3.69/5.0, with 55.8% indicating positive perceptions and 63.6% reporting increased participation. Affective dimensions recorded the highest scores, particularly pride in completing group videos (M = 4.25) and enjoyment of engaging materials (M = 4.11), whereas cognitive aspects such as comprehension improvement showed moderate levels (M = 3.41). Thematic analysis yielded eight themes highlighting enhanced engagement, creative pride, peer-mediated comprehension, and visual learning motivation, alongside time management and social interaction challenges. The study demonstrates that video-based presentations enhance affective and behavioral engagement while fostering creativity and participation. However, moderate cognitive impact suggests structured pedagogical guidance is needed. These findings extend multimedia learning theory by demonstrating how peer-created videos transform passive reading into dynamic collaborative learning experiences, particularly relevant for EFL contexts.

This study analyzes the role of strengthening farmer group institutions in increasing coconut (Cocos nucifera) production in Majene Regency using a quantitative approach. The study was conducted by collecting primary data in the form of questionnaires from farmers who are members of farmer groups and secondary data from relevant agencies. To measure the impact of institutional strengthening on production performance, the researcher used the Coefficient of Variation (CV) as an indicator of production stability before and after institutional intervention. The analysis results show a decrease in the CV value of coconut production, reflecting an improvement in stability and consistency of farming outputs after strengthening the farmer group institutions. This study reinforces recent literature findings that more active institutional organizations can improve farmers' access to information, technology, and market support, thereby positively affecting farm productivity (Indonesian Agribusiness Journal, 2025). Furthermore, these findings are in line with the results of agribusiness institutional studies which show that a strong institutional structure contributes significantly to the performance and strategy formulation of farmer groups (Agrica Journal, 2024). Therefore, strengthening the institutional capacity of farmer groups is recommended as a policy strategy to support the sustainable increase of coconut production in production center areas

The increasing volume of cross-border trade and investment has positioned international contracts as the primary legal instrument governing global business relationships. Along with this development, the potential for contractual disputes between parties subject to different legal systems has intensified. Litigation before national courts is often considered ineffective in resolving international contract disputes because of jurisdictional constraints, lengthy procedures, and difficulties in the recognition and enforcement of judgments. Consequently, Alternative Dispute Resolution (ADR) has emerged as a more flexible and efficient mechanism within international contract law. This study aims to analyze the legal regulation of ADR in international contract law through a case study of Russia and Indonesia. This study employs normative legal research methods using statutory, conceptual, and comparative approaches. The data are derived from primary, secondary, and tertiary legal materials relevant to the regulation of ADR in both countries. The findings indicate that both Russia and Indonesia have normatively adopted international ADR principles, particularly arbitration, and are parties to the 1958 New York Convention. Nevertheless, significant differences exist in the implementation and effectiveness of ADR, influenced by the characteristics of their respective legal systems, policies, and judicial practices. This study concludes that although the normative frameworks governing ADR in Russia and Indonesia are largely aligned with international standards, further strengthening of consistent application and legal certainty is required to ensure the optimal functioning of ADR in the resolution of international contract disputes.

The open model as the one the application of Leontief model using the explanation of the economy with input-output model. The open model shows the number of productions needed to satisfy an increase in internal and external demand. By using the operation linear algebra operation on ring characteristics, then the production numbers are calculated. This method is applied on the ten product-producing commodities of North Sumatera export demand to find the total production number, while the amount of demand is defined. It shows a solution to the minimization linear program is the solution that will satisfy both internal and external demands of the commodity with minimum inventory level.
