Abstract

The study entitled Characteristics of Food Tree Habitat and Langur Population in Jeruk Manis Tourism, Kembang Kuning Resort, TNGR aims to understand the role of habitat in the survival of the Javan langur (Trachypithecus auratus), an endangered primate species. The Javan langur functions as a natural seed disperser in the forest, and its presence is very important for the plant regeneration process. This study was conducted in November-December 2024 in Kembang Kuning Village, East Lombok, using the population census method and vegetation analysis. The research method includes collecting data on the langur population through the concentration method and vegetation analysis by creating sample plots measuring 20 x 20 m. The results showed that the langur population varied in various plots, with a higher proportion of adult individuals in some locations, indicating group stability. The data also showed that the bajur tree (Pterocarpus indicus) was the main food source with a high Importance Value Index (INP) value. This study provides insight into the composition and structure of vegetation in the langur habitat, as well as the importance of conserving this species in the face of threats from hunting and habitat loss. By understanding the characteristics of the habitat and distribution patterns of the langur population

Abstract

The micro-scale tofu-tempeh industry in Abian Tubuh Baru Village has a strategic economic role, but its production activities produce liquid waste with a high organic load that risks degrading the aquatic ecosystem. This study aims to analyze in depth the behavior of micro-business actors in liquid waste management, as well as the community's social response to waste disposal in the Abian Tubuh Baru Village Watershed. The research method used is descriptive qualitative with a case study approach. Data were collected through field observations and in-depth interviews with business actors and the surrounding community who were selected purposively until data saturation was achieved. Data analysis was carried out thematically using the Miles & Huberman interactive model. The results showed that liquid waste is still discharged directly into water bodies without treatment due to the persistence of habitual factors, limited environmental literacy, and the absence of waste processing infrastructure facilities. This condition causes a significant decline in river water quality, characterized by changes in physical parameters (color and turbidity), and the emergence of a pungent odor due to organic decomposition. The community shows a tendency to act passively through environmental normalization by choosing to stop using river water rather than carrying out social control. These findings imply the urgency of community-based environmental awareness-building interventions for sustainable river pollution mitigation.
