Abstract

ARTICLE HIGLIGHTS- High demand for environmental services makes the park vulnerable to human activities.- Both ecosystems are well regenerated; seedling > sapling > pole > tree (inverted J)- Both ecosystems show normal diversity conditions and stable species distribution.- Growth of Maesopsis eminii needs monitoring to preserve forest purity.- Montane forests have greater biomass, carbon stocks, less anthropogenic disturbanceABSTRACTThe Gunung Gede Pangrango National Park (GGPNP) area is one of the vital ecosystems that support the environment in West Java Province, Indonesia. It is a unique area that has multiple forest ecosystems, including lowland rainforest and montane rainforest ecosystems. Despite the GGPNP’s status as a conservation area, the high demand for the GGPNP’s environmental services makes the region vulnerable to disturbances from human activities. Several studies have been conducted in the GGPNP area (lowland and montane forest ecosystems), however, the results of this study are still necessary to explain the forest dynamics and forest carbon sequestration in this location. The objective of this research was to analyze the structure, composition, and carbon sequestration of stands in the lowland and montane rainforest ecosystems in the GGPNP area. Data processing and analyses were conducted using diversity indices, biomass-carbon stock estimation, and carbon dioxide sequestration estimation. The results showed that the GGPNP lowland and montane rainforest ecosystems were well regenerated. The number of seedlings > saplings > poles > trees and the graph showed a reverse “J” pattern. The GGPNP lowland rainforest ecosystem was dominated by Neonauclea lanceolata and had relatively higher species diversity. The GGPNP montane rainforest ecosystem was dominated by Castanopsis acuminatissima with a higher individual density, denser canopy, and more complex canopy strata. The lack of regeneration in several species of trees heightens the threat to these species’ existence in the future. Biomass, carbon stocks, and carbon sequestration in the GGPNP montane rainforest were greater than those in the GGPNP lowland rainforest. The GGPNP montane rainforest ecosystem had older forest stands, a larger average tree diameter, and lower potential for anthropogenic disturbances.

Abstract

In the surrounding areas of Gunung Merapi National Park, grass harvesting is an inseperable part of the daily life of buffer zone communities. Natural growing grasses in the Kemalang resort area have been traditionally used for livestock feed, particularly through a conservation partnership scheme facilitated by the national park authority. In the context, natural resource management must adopt a sustainable development approach to maintain the balance between ecological, economic and sociocultural aspect especially by ensuring that utilization doesn’t exceed the land’s productive capacity. This research was conducted from august 25 to november 30 2022, within the conservation partnership area of kemalang resort, under the management of Gunung Merapi National Park region II. The study aimed to determine the productivity value, utilization levels and their economic value of grass within the conservation partnership scheme. A descriptive quantitative was used, involving field observations through the establishment of 42, 1x1m2 grass sampling plots. Quantitative data were also collected through structured intreviews to 42 landowner respondens selected via purposive sampling with a sampling intensity of 10%. Direct economic valuation was applied using actual market prices. The results show that grass productivity in the area reached 3.782.790,53 kg/year with an economic value of IDR111.867.536 /year. Meanwhile, thecommunity’s utilization reached 9.483.533,42 kg/year, with an economic valued at IDR7.808.895.167 /year. This significant gap reflects pressure on the regenerative capacity of grass resources, potentially threatening the area’s ecological functions. Sustainable non-timber forest product management is therefore essential to maintain a balance between conservation and the community needs.

Abstract

Sampah merupakan sektor penyumbang emisi gas rumah kaca (GRK) di Indonesia. Kabupaten Bantul di Daerah Istimewa Yogyakarta berpotensi besar menyumbangkan emisi gas rumah kaca dari sampah yang berasal dari sektor rumah tangga, pertanian, peternakan, dan wisata. Dari jumlah rata-rata sampah yang mencapai hampir 500 ton per hari, lebih dari 50 % adalah sampah organik. Timbunan sampah organik di tempat-tempat pembuangan sampah mengalami dekomposisi anaerobik, dan proses ini menghasilkan gas metana, yang merupakan GRK sangat kuat. Selain metana, GRK yang potensial dihasilkan dari sampah adalah CO₂ yang berasal dari dekomposisi aerobik, pembakaran sampah, transportasi dan pengolahan sampah pada fasilitas pengolahan sampah bermesin yang menggunakan bahan bakar fosil. Pengelolaan sampah yang baik dan berkelanjutan, seperti pengurangan sampah dari sumbernya, pemilahan, daur ulang, pengomposan, dan teknologi pengolahan sampah yang menghasilkan energi dengan emisi rendah, sangat penting dalam upaya pencegahan (mitigasi) pemanasan global dan perubahan iklim. Kegiatan yang ditujukan untuk meningkatkan pengetahuan dan ketrampilan masyarakat dalam mengelola sampah perlu terus dilakukan, termasuk yang dilaksanakan di Kalurahan Parangtritis. Sasaran kegiatan ini adalah kelompok tani dan peternak, termasuk juga kelompok masyarakat yang bekerja di kawasan wisata pantai di Parangtritis. Kegiatan dilaksanakan menggunakan metode sosialisasi (ceramah) tentang pengelolaan sampah yang mencakup pengurangan dan penanganan sampah, dilanjutkan dengan pelatihan ketrampilan mengolah berbagai sampah organik. Melalui kegiatan ini dihasilkan produk (pupuk organik cair, kompos, decomposer, eco enzyme), video pengolahan, dan publikasi pada jurnal nasional. Disimpulkan bahwa kegiatan pelatihan ini dapat meningkatkan pengetahuan dan ketrampilan warga masyarakat Kalurahan Parangtritis dalam mengelola dan mengolah sampah organik.
