Abstract

Food estate development is one of ten National Strategic Programs (PSN) for 2020-2024 carried out by the government to restore the economy due to the impact of the COVID-19 pandemic. The government, through the Minister of Public Works and Public Housing (PUPR), stated that the food estate project was carried out on a potential land area of 165,000 ha, which is an alluvial area, not peat, on former Peat Land Project (PLG) land in Central Kalimantan. PLG was a government policy during the New Order era, with the opening of one million hectares of PLG to address agricultural development's challenges to achieve self-sufficiency. In 1998, this program was discontinued because it was considered unsuccessful in its planning and implementation, which did not pay enough attention to environmental impacts. This study examines government policy in implementing the food estate program on former PLG land in Central Kalimantan. The study covers environmental and socio-economic aspects that are affected by the food estate program on former PLG land. The research method applies a qualitative approach by searching literature reviews on implementing food estate projects on former PLG land in Central Kalimantan. The results show that government policy through the Minister of Environment and Forestry Regulation Number 24 of 2020 regulates two schemes for providing forest areas for the food estate program, namely through schemes for changing the designation of forest areas and establishing forest areas for food security. Both schemes could accelerate environmental exploitation and deforestation in Central Kalimantan, which previously experienced failure in the Million Hectare PLG project. In the socio-economic aspect, food estate development must involve the surrounding community, and it is necessary to improve the quality of farmers, which includes 1) increasing knowledge, skills, and community assistance, 2) facilitating the opening of marketing networks, and 3) establishing institutions between stakeholders at the local and central levels. Implementing the food estate program in Indonesia requires an operational strategy using strong sustainability theory to minimize environmental, economic, and social impacts so that program failure does not occur as in previous policies.

Abstract

Tahura Pancoran Mas, located in Depok City, West Java Province, is Indonesia's first nature reserve and constitutes a critical area for ecological research. Despite its significant ecological role, detailed data on tree diversity and Leaf Area Index (LAI), which represents canopy density, have not been systematically recorded across its management zones, namely the Protection Zone, Utilization Zone, and Collection Zone. This study aimed to analyze tree diversity and canopy density (LAI) across these three zones. Tree diversity data were collected using a modified transect line method consisting of nine plots, each measuring 20 × 20 meters. Canopy structure was recorded using digital hemispherical photography, tree species diversity was measured using the Shannon-Wiener index (H'), and LAI values were processed using the Hemiview software. A total of 81 individual trees were recorded, representing 20 species belonging to 13 families. Dominant species were identified in each zone: Artocarpus elasticus Reinw. ex Blume in the Protection Zone, Arenga pinnata (Wurmb) Merr. in the Utilization Zone, and Sandoricum koetjape (Burm.f.) Merr. in the Collection Zone. Biodiversity evaluation revealed that the mean Shannon-Wiener index across all three zones fell within the moderate category (Protection Zone H' = 2.20; Utilization Zone H' = 1.75; Collection Zone H' = 2.35). LAI results indicated that canopy density was classified as very dense, with values of 2.89, 2.92, and 2.84 in the protection, utilization, and collection zones, respectively. These findings may serve as a scientific reference for developing sustainable management strategies for the Tahura Pancoran Mas area, including planting native tree species appropriate to the ecological conditions of the Utilization Zone, environmental education programs, and periodic vegetation monitoring.
