Abstract

The Telaga Warna Nature Reserve and Nature Park is one of the animal and fauna conservation and protection areas in West Java, with an area of ​​496.49 ha. The long-tailed monkey is one of the protected animals at Telaga Warna. Based on the IUCN Redlist, long-tailed monkeys are currently included in the endangered species (Endangered). The largest decline in the long-tailed monkey population is due to illegal hunting. Given the declining condition of the long-tailed macaque population, this study was conducted to analyze the demographics of the population and analyze the home ranges of long-tailed macaques in Telaga Warna. The research was conducted in March-May 2021, which was carried out at CA and TWA Telaga Warna. The data collected includes population demographics, home ranges, and habitat use. Analysis of population demographic data used concentration calculations based on sex and age structure, home ranges using a minimum convex polygon and habitat use was analyzed descriptively by comparing conditions between observed groups of long-tailed monkeys. The results of the research on the long-tailed monkey population in the Telaga Warna area consisted of two groups with a total of 64 individuals. The long-tailed macaque population will decrease because it has a regressive population with sufficient space and a low total population density of 0.13 ind/ha. The home range area of ​​group A is 13.8 ha and that of group B is 6.26 ha. The home range area of ​​group B is thought to be influenced by the size and age structure of the group. The long-tailed monkey group both use forest land cover, plantations and water bodies, and are found at an altitude of 1400-1600 masl with gentle to very steep slopes (> 8%).

Abstract

Introduction: The community's behavior, perceptions, and willingness to pay (WTP) are vital in forming and implementing integrated waste management. Thus, zero waste theory advocates the need for research on perceptions, behavior, and WTP for school waste management. This study analyzes school residents' perceptions, behavior, and WTP regarding waste management. Methods: This study used a mixed-methods sequential explanatory design, combining quantitative and qualitative approaches. The study was conducted at SDN Betahwalang, selected purposively due to its active waste bank program. A total of 86 students and 75 school community members were surveyed. Quantitative data were analyzed using crosstabs and the Contingent Valuation Method (CVM), while qualitative data were obtained through in-depth interviews with key stakeholders. Results and Discussion: This study used a mixed-methods sequential explanatory design. The research was conducted at SDN Betahwalang, purposively selected for its active school waste bank program. The variables measured included students’ socio-economic characteristics, perception, environmental behavior, and willingness to pay for waste bank development. A total of 86 students and 75 school community members were surveyed. Data were analyzed using crosstabs and the Contingent Valuation Method, supported by qualitative insights from in-depth interviews. Conclusion: This study concludes that integrating environmental education through both formal and non-formal approaches effectively improves students’ knowledge, perception, and behavior toward waste management. Furthermore, the school community shows strong support for waste bank development, as indicated by their willingness to pay. These findings highlight the importance of institutional synergy and continuous environmental education in promoting sustainable waste practices in schools.
