Abstract

Negara-negara di dunia, khususnya Eropa, Jepang, Korea Selatan dan China, mulai beralih ke penggunaan energi terbarukan yaitu pelet kayu. Indonesia dengan iklim tropis, keanekaragaman jenis tanaman dan ketersediaan lahan untuk pengembangan sumber energi ini, berpeluang menjadi salah satu produsen utama pelet kayu, baik untuk memenuhi permintaan nasional atau internasional. Daerah Istimewa (DI) Yogyakarta merupakan salah satu provinsi di Indonesia yang memiliki hutan rakyat dan berpeluang untuk dikembangkan sebagai produsen pelet kayu. Penelitian ini bertujuan untuk memperoleh informasi awal tentang jenis tanaman kayu potensial di DI Yogyakarta. Pengambilan data dilakukan dengan studi pustaka dan survey kepada Kelompok Tani Hutan (KTH) di Kabupaten Bantul (22 KTH), Gunungkidul (15 KTH), Kulonprogo (15 KTH) dan Sleman (19 KTH). Cabang dan ranting kering merupakan sumber bahan bakar kayu utama bagi KTH di DI Yogyakarta, tanpa melihat jenis tanamannya. Jenis kaliandra (Calliandra calothyrsus) dan gamal (Gliricidia sp.) sebagai jenis potensial untuk pelet kayu ditanam sebagai sumber hijauan makanan ternak, sumber nektar untuk peternakan lebah madu dan untuk konservasi tanah. Kedua jenis ini ditanam sebagai tanaman tepi di pinggir lahan, diantara tanaman pertanian dan atau tanaman berkayu, bukan sebagai tanaman utama. Jumlah yang ditanam sangat variatif berkisar antara 0 - 2000 pohon kaliandra/ha dan 0 - 3000 pohon gamal/ha. Berdasarkan hasil tersebut diketahui bahwa jenis potensial untuk produksi pelet kayu, kaliandra dan gamal sudah ditanam di 4 kabupaten tersebut. Namun penanaman kedua jenis tersebut perlu dikembangkan agar dapat mendukung produksi pelet kayu.

Abstract

Energy policy in the world has changed due to the climate crisis. As a result, the need for renewable energy supply is increasing. Trees in the forestry sector are a reliable source of biomass for renewable energy production. Community forests could play an important role in supplying biomass-based renewable energy production. The study aims to understand the attitude, subjective norms, and perceived behavioural control on Farmers Forest Group's intention in cultivating trees for energy in Yogyakarta Province. The Theory of Planned Behaviour approach was used to analyse the correlation between Attitudes, Subjective Norms, and Perceived Behavioural Control on Forest Farmers Group Intention in cultivating trees for renewable energy. A survey using an online questionnaire was conducted on Forest Farmers Groups in four districts in DI Yogyakarta; Sleman, Kulonprogo, Bantul, and Gunungkidul. The survey results were analysed using non-parametric statistics.The results showed a significant positive correlation between Attitudes, Subjective Norms, and Perceived Behavioural Control on the Forest Farmers Group's Intention to cultivate trees for renewable energy. The study provides policymakers and privates with insight into working with the farmers when they are about to implement biomass-based renewable energy programs

Abstract

Surface mining, including tin mining, is the most common mining practice in Indonesia. The existence of mining ore or minerals close to the surface soil is the reason for carrying out this mining method. The process of mining surface resulted in the change of land landscape, which may cause soil erosion and even flood. It has caused various ecological and environmental problems, including soil degradation. This study describes soil physio-chemical properties impacted by surface tin mining in Bangka, Indonesia. Soils were collected from three different land use in natural forest, agroforestry, and post tin mining area in Bangka Regency, Province of Bangka Belitung Island. Five-spot soils were sampled from each site. Each site had three replication of the sampling area. The plot size for each site is about 200-500 m2. Soil texture, pH, total N, available P, exchangeable K, organic carbon, C/N ratio, CEC, Al3+, and H+ were analyzed. The results showed that mining decreased organic carbon, total N, available P, exchangeable K, and CEC. Mining changed the soil texture to be dominated by quartz sand. These results indicate that mining significantly deleterious soil fertility, therefore, potential as a limiting factor for plant growth, which could be a hamper for restoration efforts of post tin mining areas. Keywords: tin mining, restoration, soil physiochemical properties, soil degradation

Abstract

Ebony (Diospyros spp.) is a fancy wood distributed in eastern Indonesia. D. celebica Bakh, D. lolin Bakh, D. pilosanthera Blanco, D. ebenum Koenig, D. ferrea (Wild.) Bakh and D. rumphii Bakh are categorized as "Fancy Wood Class I" in the Indonesian market. These woods are an important product with the highest tax compared to other grades. This study aimed to identify the distribution of six ebonies based on data global biodiversity web service (Global Biodiversity Information Facility) and their climatic condition based on global climate data (WorldClim). Data from the web service, species occurrence, and climatic conditions were processed using QGIS. Species occurrence data was then extracted using GBIF occurrence. Furthermore, species occurrence data was then overlaid with climate data using point sampling tools. The results found that three ebonies scattered in the tropics and three others (D. celebica Bakh, D. rumphii Bakh, D. lolin Bakh) mostly occurred in Indonesia. Annual rainfall and temperature conditions ranged from 1,722 − 4,013 mm and 23.4 − 27.2°C for the three species of ebony in Indonesia. The distribution and climatic conditions of ebony are the initial information for further research, such as the species distribution model related to climate change and the genetic conservation agenda. Keywords: ebony, global data, occurrence data, precipitation, temperature

Abstract

Tin mining produced massive tailings which dispersed across the land in the post-tin mining area, transforming the landscape into a hilly or basin landscape. The dominated white silica sand in this area is prone to erosion from water and wind, resulting in soil nutrition deficiency, meanwhile, heavy metal levels were found to be elevated. This condition makes it difficult for organisms to live in such a degraded post-tin mining area. Phosphate solubilizing microorganisms (PSM) contribute to phosphate availability by dissolving both fertilizers and bounded P in soil. This study aimed to select indigenous PSM collected from post-tin mining areas. Zea mays spp., the tested plant, was grown in sterilized sand to avoid the possible nutrient content, particularly phosphate, in the soil. Rock phosphate Granufos (containing 20% P2O5) was applied in sterilized sand (v: v= 1:100) as the source of limited and insoluble P. The 17 indigenous PSM were tested by inoculating them into Zea mays spp. growing in sterilized sand. Non-inoculated Zea mays spp. were prepared as well as control. Inoculation of 17 indigenous PSM significantly had higher soil available phosphor in comparison to control. Two PSM of P7 and P15 significantly had higher shoot concentrations among treatments. The isolate of P5 had the highest shoot dry weight among treatments. Overall, all PSM inoculations improved growth performance due to increased soil available P and improved shoot P uptake. These findings suggest that indigenous PSM potentially fills nutrient deficiencies, particularly P as a macronutrient needed to rehabilitate degraded post-tin mining areas.

Abstract

Social forestry is a scheme chosen by the government to improve community welfare by providing legal access to communities to manage forests. One of the social forestry schemes implemented in Kulon Progo is Community Forestry. This scheme has great potential to be developed with a multi-use forestry management model. Therefore, a review of the silvicultural aspect is needed to understand the forest management model currently implemented. This research aims to identify tree species, planting patterns and silvicultural systems implemented by Community Forestry at Production Forests in Kulon Progo. The research was conducted from August to October 2023 in Plot 17 and Plot 19 of RPH Kokap, BDH Kulon Progo-Bantul. Observations were made by making measurement plots of 20 m x 40 m of each plot and then recording the name of tree species, coordinates, height, diameter, height without branches, and canopy width. The data were then analyzed using Spatially Explicit Individual-based Forest Simulator (SexI-FS) software version 2.1.0. to see the projected planting pattern. The results of the research showed that tree species planted in the Community Forestry were teak (Tectona grandis), acacia (Acacia mangium), mahogany (Swietenia macrophylla), eucalyptus (Eucalyptus sp.), paperback (Melaleuca leucadendron), and jackfruit (Artocarpus heterophyllus ). These species were planted using a mixed planting pattern with the silviculture system of selective logging with artificial regeneration.
