Abstract

The buffer zone of the Bukit Rimbang Bukit Baling Wildlife Reserve (BRBB WR) has been experiencing rapid land use changes due to demographic and economic pressures. This study simulated land-use change dynamics using a business-as-usual (BAU) approach to understand land transformation patterns in the absence of policy interventions. A dynamic system modeling approach was employed, with key variables including population growth, expansion of residential areas, and the extension of agriculture and plantations. The analyzed data comprised spatial land cover data from 2008 and 2019 as well as demographic data from 2019 to 2023. The simulation results indicate that without intervention, primary forests and shrublands covering approximately 1.59% and 0.62% of the study area, respectively, in 2019 will disappear before 2028. Meanwhile, secondary forests and bare lands, which occupy 18.65% and 3.83% of the area, respectively, are projected to continue declining until 2035. Conversely, plantations, agricultural land, and settlements have expanded significantly, exacerbating pressure on the ecosystem. Model validation using the Mean Absolute Error (MAE) yielded a value of 0.48%, demonstrating high accuracy in predicting land-use changes. These findings emphasize the urgent need for conservation-based policies to curb deforestation and land conversion, while promoting more sustainable resource management to maintain the ecological and socioeconomic balance in the BRBB WR buffer zone.

Abstract

This community service activity aimed to enhance the understanding and participation of the residents of Sapat Village in developing the local ecotourism potential, including mangrove ecotourism, fishing, fireflies, sailing, beaches, and the socio-cultural heritage of fishermen’s communities. The program involved socialization, discussions, and the Focus Group Discussion (FGD) method to gain deeper insights into community perspectives and assess readiness for ecotourism development. Following the activities, an evaluation was conducted to assess participants' understanding before and after the program. The results showed a significant improvement, particularly in mangrove and firefly ecotourism, with an increase in the awareness of sustainable ecosystem management. However, the potential for beach ecotourism is less favorable due to environmental limitations, such as muddy substrates and tidal conditions. The community expressed strong support for technical assistance and training to develop ecotourism initiatives, especially mangrove and fishing activities, which are expected to boost local incomes and conservation efforts. This programme highlights the importance of continuous mentoring, capacity building, and monitoring to ensure the sustainability and economic impact of community-based ecotourism

Abstract

This systematic literature review aimed to identify and synthesize nonclinical determinants contributing to the risk and management of diabetic peripheral neuropathy (DPN) in patients with type 2 diabetes mellitus (T2DM) in Indonesia. This review followed the PRISMA 2020 guidelines and included ten eligible studies published between 2021 and 2025. The analysis revealed that various nonclinical factors—including sociodemographic (age, education level, rural-urban disparity), behavioral (smoking, physical inactivity, poor self-monitoring), psychosocial (low risk perception, limited family support, emotional distress), and anthropometric-vascular indicators (high BMI, uncontrolled blood pressure, low ABI)—significantly affect DPN risk and severity. In addition, system-level factors, such as health service accessibility and national NCD control policies, influenced early detection and complication management. These findings highlight the need for an integrative, multidisciplinary approach to DPN prevention and intervention that goes beyond clinical care. Strengthening community-based health education, incorporating psychosocial support in primary care, and formulating socially responsive health policies are essential to reduce the DPN burden among the diabetic population in Indonesia

Abstract

This study examined the population dynamics of Banana Prawns (Penaeus merguiensis) in the waters of Sungai Bela, focusing on sex ratio, length-weight relationship, and natural recruitment patterns. The results show a dominance of female individuals in the population with a sex ratio of 1:1.19 (male : female), which may affect reproduction processes and population sustainability. The length-weight relationship demonstrated a negative allometric growth pattern, in which body mass grew faster than body length. Shrimp recruitment patterns show seasonal fluctuations, with recruitment peaks in July and October, which are influenced by temperature, salinity, and food availability. This study highlights the importance of continuous monitoring of the sex ratio and recruitment patterns, as well as management based on environmental factors, to support the sustainability of P. merguiensis populations. Sustainable management, including habitat conservation and catch control, is essential for maintaining ecosystem balance and ensuring the sustainability of shrimp stocks in the future.

Abstract

Marble goby (Oxyeleotris marmorata) production relies heavily on wild catches, creating a need for feed-efficient domestication strategies to support sustainable aquaculture. This study evaluated the feeding rate (FR), feed conversion ratio (FCR), specific growth rate (SGR), and survival of marble goby reared in tarpaulin ponds. Fifteen fish were cultured for 56 days in three ponds, with five fish per pond, and fed twice daily with chopped fresh trash fish to apparent satiation. The data were assessed descriptively and using quadratic polynomial regression. The mean FR ranged from 1.30 to 1.75% biomass day⁻¹, cumulative FCR from 6.53 to 10.67, and cumulative SGR from 0.19 to 0.26% day⁻¹. Pond 1 showed the most balanced performance, with an FCR of 6.53, biomass gain of 154 g, and 100% survival, whereas Pond 2 experienced 40% mortality. The FR–SGR relationship followed a quadratic pattern, with a stationary point at 1.45% biomass day⁻¹ (R² = 0.3804). This value represents an efficient feeding range rather than a definitive optimum. Controlled feeding in tarpaulin ponds supports early-stage domestication and may reduce dependence on wild marble goby stocks.

Abstract

Feed costs and organic waste accumulation remain major constraints to efficient and sustainable catfish farming, creating the need to evaluate fermented quail manure bokashi as an alternative feed ingredient. This study assessed the most effective bokashi formulation for absolute length gain, absolute weight gain, and survival of juvenile Clarias gariepinus. Fish were reared for 60 days in a completely randomized design comprising four treatments with three replicates: 100% commercial pellets (P0), 100% bokashi (P1), 25% bokashi and 75% rice bran (P2), and 75% bokashi and 25% rice bran (P3). Among the bokashi-based diets, P3 produced the best performance, with an absolute length gain of 10.60 cm, an absolute weight gain of 55.33 g, and a survival rate of 95.00%. Dietary treatments did not significantly affect length or weight gain (p > 0.05) but significantly influenced survival (p < 0.001). The mean temperature, pH, and dissolved oxygen were 29°C, 7.19, and 5.46 mg L⁻¹, respectively, indicating suitable rearing conditions. Therefore, the P3 formulation offers potential as an organic-waste-based feed alternative, although it cannot yet fully replace commercial pellets and requires further evaluation of feed efficiency, nutrient retention, and waste balance.
