Abstract

The research was conducted from June to August 2023 in Nagori Sah Kuda Bayu Pasar Baru at an altitude of ± 136 m above sea level. The purpose of the research is to determine the effect of Empty Fruit Bunches (Janjang) and NPK fertilizer on the growth and production of long bean plants (Vigna sinensis L.). This research was conducted using a factorial randomized block design (RBD), consisting of two factors: The first factor is the application of Empty Bunches, which consists: T0=without the application of empty bunches, T1=2.4kg/plot, T2=4.8kg/plot, and T3=7.2kg/plot. The second factor is the addition of NPK fertilizer doses N0=without NPK fertilizer, N1=24g/plot, N2=48g/plot, N3=72g/plot. The parameters observed in this study include: Number of Leaves (Sheets) and Plant Height (cm) at 2, 4 and 6 WAP, Number of Fruits Per Sample Plant (Pods), Weight of Fruits Per Sample Plant (g), and Weight of Fruits Per Plot (kg). The research results indicate that the NPK 17+17+17 treatment significantly affected the Number of Leaves, Plant Height, Number of Fruits per Plant, Weight of Fruits per Plant, and Weight of Fruits per Plot. The best dose of NPK fertilizer 17+17+17 is 150 kg/ha (72 g/plot).

Abstract

While Problem-Based Learning (PBL) and Wordwall have been studied individually, empirical research integrating both to address abstract science topics in elementary schools remains limited, leaving a gap in understanding how this combination interacts with students' prior knowledge. This study analyzes the influence of the Wordwall-assisted PBL model on fifth-grade students’ mastery of electrical energy concepts, considering their prior knowledge. A quantitative quasi-experimental design with a posttest-only control group was used, involving a total sample of 33 students (17 in the experimental class and 16 in the control class). Instruments included validated and reliable prior knowledge and concept mastery tests. Two-Way ANOVA results show significant main effects on concept mastery based on the learning model and prior knowledge levels (p < 0.05). The experimental group achieved a notably higher mean score (88.75) compared to the control group (66.50), with the learning model exerting a strong effect size (Partial Eta Squared,  = 0.872) on concept mastery. Crucially, no significant interaction effect was found between the learning model and prior knowledge (p = 0.861), indicating that the Wordwall-assisted PBL model consistently and uniformly enhances learning outcomes for students across all initial ability levels

Abstract

This study aims to analyze the influence of knowledge, skills, attitudes, and behaviors on the sustainable performance of vegetable farmers from the perspective of the Sustainable Development Goals (SDGs) in Napu, North Lore District, Poso Regency. Farmers’ sustainable performance is a crucial indicator in supporting agricultural development oriented toward economic, social, and environmental sustainability. The research method employed was a quantitative approach using a survey technique. Data were collected by distributing questionnaires to vegetable farmers. The data analysis technique used was multiple linear regression to determine the influence of independent variables (knowledge, skills, attitudes, and behavior) on the dependent variable (sustainable performance). The results of the study indicate that knowledge, skills, attitudes, and behavior simultaneously have a significant influence on the sustainable performance of vegetable farmers. Partially, knowledge and skills have a positive and significant effect, while attitudes and behavior also positively influence sustainable performance. These findings indicate that enhancing farmers’ capacity through education, training, and behavioral change is crucial to achieving SDG goals, particularly in food security, sustainable agriculture, and farmer well-being. The implication of this research is the need to strengthen extension and mentoring programs for farmers to improve human resource quality and encourage the adoption of sustainable agricultural practices.

Abstract

Merak Port Berth VII is exposed to wave action, seismic loading, and soft-soil conditions, while retrofit works must be planned under limited marine access and a constrained schedule. This study verifies a hybrid wave-damping system comprising a platform-mounted wavescreen and a causeway revetment to improve multi-hazard resilience. Wind data from 2010–2022 were used for wave hindcasting to derive return-period wave conditions, while seismic actions and structural checks were evaluated using Indonesian and international port design criteria. Platform performance was assessed at the ultimate and serviceability limit states, and revetment stability was analyzed using the Morgenstern–Price method. Under the 500-year design combination, the platform satisfied strength and serviceability requirements, with vertical bearing safety factors of 3.40 and 3.53 based on SNI and UFC combinations, respectively, and deformations within operational limits. The revetment achieved a factor of safety of 1.49 under the same demand but became inadequate under the 1,000-year scenario, indicating the need for strengthening when higher reliability is required. The estimated construction cost is IDR 132,205,000,000, with an estimated duration of approximately 216 working days. This verification framework is transferable to brownfield Indonesian ports exposed to combined coastal and seismic hazards.

Abstract

Large oil palm production creates opportunities for independent smallholders; however, complex marketing chains and fluctuating prices often reduce farmers’ income and bargaining power. This study offers novelty by comparing the efficiency of three different fresh fruit bunch (FFB) marketing channels among independent smallholders in Mersam District, Batanghari Regency, while simultaneously evaluating marketing margins, farmer’s share, and marketing efficiency indicators within the local supply chain structure. A survey method was employed involving 55 independent smallholders selected using proportionate stratified random sampling, while marketing institutions were identified using snowball sampling. Marketing efficiency was analyzed using marketing margin, farmer’s share, and efficiency formulas. The findings identified three marketing channels: Channel I (smallholders–small collectors–large collectors–factories), Channel II (smallholders–large collectors–factories), and Channel III (smallholders–village unit cooperatives–factories). Channel III demonstrated the best performance with the lowest marketing margin (IDR 153/kg), the highest farmer’s share (92.24%), and the lowest efficiency value (4.07%), compared to Channel I with a marketing margin of IDR 248/kg and efficiency value of 6.48%, and Channel II with a marketing margin of IDR 167.43/kg and efficiency value of 4.10%. These results indicate that cooperative-based marketing channels are more efficient and provide greater benefits to smallholders. Simplifying marketing chains and strengthening institutional collaboration can improve farmers’ bargaining position and increase the share of FFB prices received by independent smallholders.

Abstract

Lake Maninjau with its strategic functions, faces pressures from both climate change and anthropogenic activities that can degrade water quality and ecological functions. This study aims to determine the water quality status of Lake Maninjau over the 2022–2025 period as an initial step to support lake restoration and the achievement of Sustainable Development Goal (SDG) 6. Surface water samples were collected twice a year from six stations representing the lake's spatial characteristics using the grab sampling method. Analyzed parameters included pH, dissolved oxygen (DO), biochemical oxygen demand (BOD), chemical oxygen demand (COD), total suspended solids (TSS), and phosphate (PO4) following methods established in the Indonesian National Standards and relevant international standards. The water quality status was assessed using the Pollution Index method based on the Decree of the Minister of State for the Environment Number 115 of 2003. The results revealed fluctuating temporal shifts throughout the observation period. In 2022, water quality ranged from good conditions to light pollution. Conditions deteriorated during 2023–2024, with the majority of stations classified as light pollution. By 2025, all monitoring sites recovered to the good conditions. The observed fluctuating patterns of the Pollution Index during the 2022–2025 period indicate that the Lake Maninjau aquatic system remains highly vulnerable to dynamic external pressures, such as organic load accumulation and the lake's natural hydrological dynamics in the form of upwelling events. Consequently, consistent nutrient load reduction is urgently required, particularly through the regulation of floating net cage capacities based on carrying capacity assessments and structured water quality monitoring.

Abstract

This study aims to develop and evaluate an integrated science learning design based on wetland local wisdom to enhance junior high school students’ Higher Order Thinking Skills (HOTS). The study addresses the limited integration of local environmental contexts in science instruction, which often leads to low student engagement and suboptimal development of higher-order cognitive skills. A Research and Development (R&D) approach was employed using the 4D model (Define, Design, Develop, Disseminate). The developed products included lesson plans, integrated teaching materials, student worksheets, and HOTS-based assessment instruments designed to facilitate contextual and meaningful learning experiences. The validity of the developed learning design was assessed by experts, resulting in a high average validation score of 0.92, indicating strong content, construct, and language appropriateness. Practicality was evaluated through classroom implementation and student responses, showing a high implementation rate (94%) and positive student responses (88.5%), both categorized as very practical. The effectiveness of the learning design was measured using N-gain analysis, which yielded a score of 0.72, indicating a high level of improvement in students’ HOTS. Statistical analysis further confirmed significant improvements (p < 0.05), particularly in analytical (C4) and evaluation (C5) skills. In conclusion, the developed learning design is empirically proven to be valid, practical, and effective in improving students’ HOTS. It also provides a robust and innovative framework for contextual science learning through the integration of wetland local wisdom, contributing to the advancement of science education in environmentally relevant contexts

Abstract

The gap between national human resource development policies and teacher professional development practices in vocational schools is the main background of this research. This study aims to develop the "OK Bebas Shopping" (Optimization of Workshop-Based Learning Communities and Teacher Professional Collaboration) program to address the decline in teacher competency and performance at SMKN 1 Grati. The main problems identified include low Learning Community (Kombel) engagement, weak governance, teacher age, and limited access to professional development due to unstructured independent learning policies. Using Research and Development (R&D) methods, this research went through the stages of needs analysis, planning, program development, and evaluation. The research subjects included all teachers and management of SMKN 1 Grati. The developed program systematically integrated routine workshops, community discussions, lesson study, and online training (PMM). The results showed that this program was able to transform the human resource development paradigm from a top-down approach to a sustainable community-based approach. The implementation of peer teaching and mentoring strategies proved effective in increasing teacher motivation according to Herzberg's theory and strengthening the Professional Learning Community (PLC). The program's success was measured by teacher participation (>80%) and improved learning quality. It is concluded that the management of Kombel which is planned in a managerial manner and supported by a reflective monitoring system is a strategic solution in aligning national policies with field practices to improve the quality of vocational education.

Abstract

This study aims to develop a strategic planning model for excellent elementary schools based on the wetland ecosystem in the North Banjarmasin District. A qualitative approach with a case study design was employed at two high-performing public elementary schools. Data were collected through in-depth interviews, participant observation, and document analysis, and subsequently analyzed using an interactive model. The findings indicate that the characteristics of the wetland ecosystem—such as seasonal flooding, peatland, and infrastructure limitations—significantly impact the effectiveness of school strategic planning. Implementation still faces obstacles regarding curricula and facilities that are not yet fully adaptive to the environment. However, high community participation serves as a primary supporting factor in school development. This research produced a strategic planning model consisting of five key components: wetland-based strategic environmental analysis, environment-adaptive vision and mission formulation, contextual curriculum development, adaptive facilities management, and the strengthening of school-community partnerships. This model demonstrates that integrating ecological aspects into strategic planning can enhance the relevance, effectiveness, and sustainability of school management. Theoretically, this study enriches the field of educational management through an ecosystem-based approach, while practically, it provides a reference for schools and policymakers in designing contextual and adaptive strategic plans in wetland regions.
