Abstract

Inceptisol is a widespread soil with a total of 37% of the land area in Indonesia. On the island of Java, Inceptisol has an intensive management intensity, one of which is in Kertasari District, Bandung Regency, West Java, which has a high potential for soil damage due to a decrease in the soil's ability to hold water. Biochar enriched with silica and activated charcoal Oil Palm Empty Fruit Bunches (OPEFB) is a type of organic soil amendment that can improve the ability of Inceptisol to hold water and support nutrient needs through organic C indicators and cation exchange capacity. The research was carried out by taking soil samples and then incubating them according to the treatment for 14 days. The experimental design used in the study was a non-factorial, Completely Randomized Design (CRD) method with 12 levels consisting of 3 L/ha of silica-enriched rice husk biochar and OPEFB's activated charcoal, with each in the range of 0-6.25 tons/ha. Measurement results of water holding capacity parameters, C-organic, and cation exchange capacity were analyzed statistically, and significant differences in responses were obtained from the treatments. The optimum dose for Inceptisol in Kertasari uses silica-enriched biochar to increase water holding capacity, organic C, and cation exchange capacity, respectively, at 4.92 tons/ha, 5.73 tons/ha, and 2.51 tons/ha. Otherwhile, OPEFB's activated charcoal was 1.7 tons/ha, 0.125 tons/ha, and 1.5 tons/ha, respectively.

Abstract

Changes in land use and cover play an important role in sustainable natural resource management. Muaro Jambi Regency, which is rich in biodiversity, has ecosystem services for residents in the area, especially plantations which are one of the leading commodities. Forests as the largest land cover in Muaro Jambi Regency have experienced quite rapid changes, especially after forest and land fires occur almost every year. Real-time monitoring and assessment on a spatio-temporal basis is important to determine changes in land cover. This research examines changes in land cover in Sarolangun Regency from Landsat-8 time series images from 2018 to 2023. Land cover is classified into 6 classes using the supervised classification method. The data findings show that forests have experienced a significant decline, while settlements have experienced a very substantial increase. Comprehensive research regarding the vulnerability of periodic land cover changes at local and regional levels must be carried out to maintain sustainable environmental ecosystems.

Abstract

Paludiculture-based agroforestry promotes sustainable peatland-use management practices through rewetting activities on drained peatland, revegetating degraded peatland using high-value local tree species and at the same time providing economic benefits for local communities. Due to its potential benefits in maintaining balance between production and protection function of the landscape, paludiculture-based agroforestry in peatlands is purposed to support the restoration efforts. This paper explores the potential, ideal paludiculture-based agroforestry direction, and economic value. We present two scenarios for agroforestry in peatlands: 1) business as usual (BAU) agroforestry by combining native peatland tree species and dryland crops, and 2) paludiculture-based agroforestry by combining native peatland tree species and paludiculture crops. The results show that the economic value of BAU agroforestry ranges from IDR 40.32 million (US$2,826) to IDR 133.47 million (US$9,355) per hectare per year (ha/year) and paludiculture-based agroforestry from IDR 44.22 million (US$3,099) to IDR 106.73 (US$7,481) million ha/year. Taking the BAU model as baseline, the paludiculture model leads to higher emission reduction with a value of IDR 6.2 million (US$435) to IDR 25.21 million (US$1767) per ha/year relative to the BAU. This implies a wider scope of ecological and economic benefits offered by the paludiculture-based agroforestry model compared to the BAU.

Abstract

Drought is a major challenge in developing the integrated farming system (IFS) in Trenggalek Regency, making it one of the factors contributing to the construction of the Tugu Dam. Additionally, in developing the IFS area, it is necessary to assess soil fertility and land suitability evaluation for food and livestock feed commodities. The research was conducted in Tugu and Karangan Sub-Districts, Trenggalek Regency by conducting spatial analysis and soil survey at locations potentially affected by dam construction and soil samples analysis at the laboratory. The results of this study found that the level of soil fertility at the research site was included in the low to very low class with characteristics of acidic pH, very low C-organic, very low total N and low base saturation. While the results of the actual land suitability evaluation of rice, maize, and elephant grass showed the land suitability class S3 with limiting factors of C-organic, pH, total N, P2O5, and base saturation.
