Abstract

Indonesia faces the problem of forest degradation, with Forest and Land Rehabilitation (FLR) being one of the key efforts undertaken to address it. This study analyzes the formal institutional framework governing FLR implementation in Indonesia using the Institutional Analysis and Development (IAD) Framework, focusing on Ostrom’s concept of rules-in-use. Content analysis was conducted on four main regulations: Law No. 41 of 1999, Government Regulation No. 26 of 2020, Minister of Environment and Forestry Regulation No. P.2 of 2020, and Minister of Environment and Forestry Regulation No. P.23 of 2021. The findings show that seven types of institutional rules, position, boundary, choice, aggregation, information, scope, and payoff rules, are included in these regulations, but they are not yet fully synchronized. The distribution of roles among actors remains overlapping, coordination mechanisms are weak, and incentive rules are not clearly defined. Moreover, the regulations tend to emphasize administrative and physical aspects of planting rather than ecological and social outcomes. Weaknesses in this rules-in-form structure create unstable action arenas and reduce policy effectiveness. This study highlights that the success of FLR is determined not only by technical aspects but also by the clarity and consistency of formal rules. Harmonization of regulations, strengthened cross-actor coordination, and transparency of information are needed to ensure that FLR implementation supports the sustainable restoration of the forest’s ecological and social functions

Abstract

Natural fibers from pineapple leaves (Ananas comosus L.) are a potential renewable resource, but their characteristics are highly dependent on their geographical origin. This study aimed to characterize the physico-mechanical properties and morphology of pineapple leaf fibers (PALF) sourced from local farmers in Kediri, East Java. Characterization was conducted at an accredited testing institution using SNI standards, covering fineness, bundle tenacity, and Scanning Electron Microscopy (SEM) observations. The results revealed that the fibers exhibited an average fineness of 33.7 dtex and a tenacity of 23.20 g/tex. Morphological analysis showed a course, multi-cellular, and dense fiber structure. Based on these findings, it is concluded that these PALF demonstrate greater potential for applications in technical textiles and as reinforcement in bio-composite materials rather than as a raw material for apparel yarn.

Abstract

Education plays an important role in improving human resources and shaping adaptive character. To address post-pandemic learning challenges, Indonesia introduced the Merdeka Curriculum, emphasizing flexibility and competency development. This study evaluates the Merdeka Curriculum implementation at SMKN 1 Luak, Lima Puluh Kota Regency, West Sumatra, using the CIPP (Contextual, Input, Process, Product) model. The evaluation covers the 2023/2024 academic year, following its introduction in 2022. A mixed-method approach (qualitative and quantitative) was used for data collection through observations, interviews with teachers, students, and administrators, and analysis of relevant curriculum documents. The results indicate that the context aspect (National Education Standards and School-Level Curriculum) is very good (91.11%). The input aspect (teacher qualifications, infrastructure, reference books) is generally good, but there are shortcomings in qualified teachers, reference books, and subject guidelines. The learning process is rated as adequate (77.18%), with challenges in teaching strategies and student engagement. Student learning outcomes were rated as adequate (79.12%), with room for improvement in critical thinking and problem-solving skills. The Merdeka Curriculum positively impacts education quality, but improvements in facilities, teacher training, and motivation are needed to optimize its effectiveness. These findings suggest schools with similar contexts can benefit by focusing on teaching infrastructure and professional development.

Abstract

Environmental awareness among preservice teachers is an essential component of environmental education, yet its development is often influenced by limited knowledge and insufficient integration of environmental issues in higher education. This study aims to analyze the level of environmental awareness of prospective chemistry teachers based on three dimensions: knowledge, attitude, and behavior. A quantitative descriptive design was employed involving 127 students selected through purposive sampling. Data were collected using a validated questionnaire with a 5-point Likert scale, and analyzed descriptively by determining mean scores and category levels. The results showed that environmental awareness was in the moderate category for the knowledge aspect (M = 3.31) and in the high category for both attitude (M = 3.72) and behavior (M = 3.67). These findings indicate that students demonstrate positive attitudes and environmentally responsible behavior despite having limited conceptual knowledge. The study concludes that strengthening environmental knowledge through integrated instructional strategies, exposure to scientific literature, and collaborative environmental programs is essential. Further research should explore intervention-based models to enhance environmental literacy and examine factors influencing awareness development across different teacher education programs.

Abstract

This study investigates the use of lime-based flocculants as a treatment method for Sidoarjo mud (LUSI) to improve solid–liquid separation and reduce the environmental impact of its discharge into the Porong River. Several commercial lime-derived flocculants were tested through jar experiments to evaluate their effectiveness in promoting particle aggregation and enhancing settling behavior under conditions similar to the existing treatment pond. The results indicate that a mud-to-water ratio of 1:4 provided the most efficient sedimentation performance, reflected by faster settling rates and clearer supernatant. Among the flocculants examined, differences in chemical composition and particle morphology influenced the degree of aggregation and overall clarity of the treated water. The treatment substantially reduced turbidity and suspended solids, while also lowering chloride levels in the clarified water. These findings suggest that lime-based flocculants are a feasible option for mitigating the environmental burden of LUSI mud disposal by improving separation efficiency.

Abstract

Flash floods are among the most destructive hydrometeorological hazards in tropical highland regions, yet their spatial risks remain poorly quantified in data-scarce environments. This study assessed flash flood risk in Solok Selatan Regency, West Sumatra (Indonesia), by integrating landform and slope classification with the Topographic Wetness Index (TWI) derived from a 30 m DEM. Historical records of 11 flood events between 2010 and 2020 were used for model validation. The analysis revealed that most of the regency is characterized by moderate flash flood risk, while high-risk zones are concentrated in steep fluvial landscapes. Validation against observed flood locations demonstrated a spatial match of 95.2%, confirming the reliability of the model. In addition, the evaluation of hydrological ecosystem service capacity indicated that over 80% of the landscape has only moderate regulatory function, limiting its ability to buffer runoff. These findings highlight the importance of integrating DEM-based hydrological indices with ecosystem assessments to support more effective disaster risk reduction and spatial planning in tropical highland environments.

Abstract

This study aimed to evaluate the effect of mixing watermelon rind (Citrullus lanatus) and kweni mango (Mangifera odorata Griff.) on the color and sensory quality of slice jam while promoting the utilization of fruit-processing by-products. The experiment employed a Completely Randomized Design (CRD) with four treatment ratios of watermelon rind to kweni mango pulp: P1 (20:80), P2 (30:70), P3 (40:60), and P4 (50:50), each replicated three times. Color parameters (L*, a*, b*) were measured using the Color Grab application, and sensory evaluation of color, aroma, taste, and texture was conducted by 25 untrained panelists using a seven-point hedonic scale. Results showed that increasing the proportion of watermelon rind significantly enhanced lightness (L*) and yellowness (b*) while decreasing redness (a*). The sensory test indicated that the P4 formulation achieved the highest overall preference score (5.12), corresponding to a bright golden-yellow color, balanced aroma, and chewy texture. The discussion highlights that the improvement in color and texture is associated with the higher natural pectin content of watermelon rind, which contributes to gel formation and product stability. Moreover, combining kweni mango and watermelon rind demonstrates a viable approach for valorizing agricultural waste into value-added food products. In conclusion, the 50:50 mixture produced the most acceptable slice jam, confirming that watermelon rind can serve as a sustainable, functional ingredient to enhance product quality and support circular-economy practices in tropical fruit processing

Abstract

In the 21st-century education era, scientific literacy has emerged as a crucial competency for addressing global challenges. The integrated STEM (Science, Technology, Engineering, and Mathematics) instructional approach is considered a promising strategy for enhancing students’ mastery of scientific literacy through interdisciplinary integration. However, there remains inconsistency in findings regarding the effectiveness of various STEM models, particularly within the Indonesian educational context. This study aims to examine the effectiveness of integrated STEM learning models on students’ scientific literacy in Indonesia through a meta-analytic approach. A total of 10 peer-reviewed articles published between 2021 and 2025 were analyzed using the Comprehensive Meta-Analysis (CMA) software version 4. The results indicate that STEM-based learning demonstrates a high overall effect size of 0.995 (categorized as large, p < 0.001). Among the models examined, Project-Based Learning (PjBL) emerged as the most effective and consistent model, while Problem-Based Learning (PBL) exhibited a relatively smaller effect size. Other models, such as Blended Learning, Inquiry Learning, and RADEC, also showed very high effectiveness; however, these findings require further empirical validation through additional studies. Moderator analysis revealed significant differences across the models (Qb = 7.85; p = 0.005), suggesting that the type of instructional model moderates the effectiveness of the STEM approach. These findings support the development of more evidence-based and contextually relevant science teaching strategies tailored to the Indonesian educational landscape.
