Abstract

Peatlands are important ecosystems that play a crucial role in maintaining environmental balance, particularly in tropical regions such as Palangka Raya, Central of Kalimantan. This study aims to identify the physical and chemical characteristics of peat soils surrounding the Laboratorium Terpadu area at Palangka raya University, to support sustainable land management and campus environmental conservation. The results indicate that the peat soils at the site have a high water content (111.1%) and low bulk density (0.22 g/cm³), reflecting saturated, porous soil with a potential risk of subsidence if hydrological conditions are altered. Soil chemical properties show a pH of 4.3, indicating high acidity with low nutrient availability, and reflecting a relatively natural ecosystem. These physical and chemical characteristics have important implications for land use planning, vegetation cultivation, and campus spatial development, emphasizing the need for amelioration strategies, proper fertilization, and construction techniques that account for soil subsidence risks. This study provides a scientific basis for the wise and sustainable management of peatlands within the campus environment.

Abstract

Telaga Warna Bogor is a conservation area consisting of a Nature Reserve (CA) and Telaga Warna Nature Park (TWA) which harbors potential flora and fauna. The Long-tailed Macaque is one of the protected animals in the area and, with the rise of its IUCN conservation status, has been included in the red list of endangered species. The purpose of this study was to determine the food preferences of Long-tailed Macaques in the Telaga Warna area. The method used to determine food preferences was the line transect method, while the potential food trees were identified using the grid method, supplemented by a literature study for additional data on food preferences. The data analysis used was descriptive and qualitative. The food plant data was analyzed to determine density, frequency, dominance, and INP. The results of the study showed that the INP analysis of Villebrunea rubescens (42.21), Slonea sigun (33.82), and Castanopsis Argentea (22.91) had the highest values of the 17 food trees, indicating that these three plant species are quite abundant and have high potential as food for long-tailed macaques. The parts of plants most frequently eaten by long-tailed macaques were the fruit (47%), followed by the flowers (29%), and the leaves (24%).

Abstract

The Community Plantation Forest (CPF) program was established as a policy instrument to expand community access to forest management, support forest rehabilitation, and improve local livelihoods. However, its implementation in Barru Regency, which holds one of the largest allocations of HTR permits in South Sulawesi, has remained stagnant since the early phase of the program. This study aims to identify the factors influencing the implementation of HTR management and to examine community interest in the program. Data were collected through field observations and interviews conducted with Forest Farmer Group’s (FFGs) using a key informant sampling method. The factors affecting policy implementation were analyzed across five dimensions: policy, institutional arrangements, stakeholders, human resources, and forest resources. The findings indicate that strengthening community capacity and institutional structures, enhancing stakeholder collaboration, and implementing consistent monitoring and evaluation mechanisms are essential to improving the performance and long-term sustainability of the HTR program in Barru Regency.
