Abstract

Agroforestry is a land management system that can overcome food problems, the application of which is to combine two or more types of plants, both forestry and agricultural crops. The application of agroforestry in Lampung has been implemented, one of which is Pesawaran Sub-village, Pesawaran Village, Kedondong District, Pesawaran Regency, Lampung. The contribution obtained from forest land using an agroforestry system to people's income is the yield of agricultural crops on a weekly, monthly or annual basis, depending on the type of agricultural crops planted. This study aims to determine the contribution of agroforestry to income and the factors that influence farmers' income in Sejahtera 4 Forest Farmers Group (FFG). This study uses interview and observation methods and multiple linear regression to analyze the data. The results show that agroforestry contributes 25.64% of income, or around Rp. 111,306,690 lower than that of non-agroforestry, contributing 74.36% of income or around Rp. 322,800,000. The results of the analysis show that age has a significant effect on farmers' income in FFG of Sejahtera 4. In contrast, plot area, number of plant species, the combination of plant types, and level of education have no significant effect on income.

Abstract

Timber harvesting does not only have to produce good quality logs, but the important thing is also to meet the quantity of wood for industrial needs. However, the process of harvesting wood, especially in logging activities in logging plots, cannot avoid the occurrence of logging waste. The purposes of this study were to determine the volume of logging waste, the volume of wood used, the percentage of waste in the logging plots in natural forest, and the factors that influence it. Primary data were taken by measuring the slope of the logging area, diameter and length of stump and stem waste in the logging plots on 85 samples in three plots, namely plots 2, 7 and 23 in 2020 Block area at PT Kemakmuran Berkah Timber. Meanwhile, secondary data consisted of tree species and the area (plot) of the study site. The results showed that the volume of stump waste in the felling plots is greater than the volume of stem waste, where the total waste stump is 46.99 m3 with an average waste volume per tree of 0.55 m3, while the total volume of stump waste is 30.2 m3 with an average volume of trunk waste per tree of 0.35 m3. The total volume of stump and stem waste is 77.55 m3 with an average waste volume per tree of 0.91 m3. The average volume of waste utilized per tree is 5.23 m3 and the average per hectare is 1.80 m3. Overall, the percentage of waste that occurred in the logging plots was 44.40%, with an average volume percentage of waste per tree of 0.52% and an average of 0.18% per hectare. The factors that influence the occurrence of logging waste at PT KBT are the diameter of the stump, the diameter of the stem waste, and the type of sinker wood.

Abstract

The demand for commercial timber in Indonesia continues to rise, while the availability of forest resources is steadily declining, both in terms of production forest area and wood quality. Many native wood species remain underutilized in the Indonesian wood industry due to limited information regarding their properties. One such species, Mindi wood (Melia azedarach Linn.), has been used by local communities but is not widely recognized as a commercial timber alternative. Mindi wood holds potential as a substitute for high-quality commercial timber; however, research on its physical and mechanical properties remains scarce. This study aims to evaluate the axial variation in the physical and mechanical properties of Mindi wood from Senanggalih Village, East Lombok Regency, and to assess the influence of axial position on these properties. The study employed a non-factorial Completely Randomized Design (CRD) with three axial sections (base, middle, and top) as treatments, each replicated three times. Results indicated that axial position significantly affected certain physical properties, including kiln-dry specific gravity, radial shrinkage (from fresh to kiln-dry), and longitudinal swelling (from air-dry to wet). However, no significant effect was observed on moisture content (fresh air or air-dry), fresh specific gravity, air-dry density, or shrinkage and swelling in the tangential, radial, and longitudinal directions for various moisture conditions. In terms of mechanical properties, no significant effect of axial position was found on Modulus of Elasticity (MoE) and Modulus of Rupture (MoR). These findings suggest that Mindi wood is suitable for light construction applications such as furniture manufacturing, as well as for composite wood products including plywood, particleboard, and fiberboard.

Abstract

A watershed is a land area that functions as an ecological unit to collect, store, and channel rainfall to lakes or seas naturally. Effective watershed management requires supportive policies and regulations. This study aims to evaluate the implementation of Regional Regulation No. 5 of 2017 on Watershed Management in West Nusa Tenggara and to formulate planning strategies to optimize the policy's implementation. The research methods included literature review, interviews, and observation. Policy analysis was conducted using four criteria derived from William N. Dunn's theory, while management strategies were formulated using SWOT analysis. The findings indicate that the policy implementation falls under the "low" category with a score of 1.58, deeming it ineffective. The highest-scoring strategy is the Weakness-Opportunities (W-O) strategy, which emphasizes optimizing Government Regulation No. 37 of 2012 and Regional Regulation No. 5 of 2017 to enhance coordination in watershed management. These findings highlight the need for strategic measures to strengthen policy implementation for watershed management in West Nusa Tenggara.

Abstract

This study aims to identify the sources of income for farmers' households from within and outside forest areas, analyze the impact of community-based forest management (HKm) on farmers' welfare, and assess the overall welfare levels of farmers' households. The research employed a descriptive method. The sampling area was determined using a purposive sampling technique, while the sample size, comprising 37 respondents, was calculated using the Slovin formula. The distribution of samples was carried out using the Proportional Random Sampling technique, and respondents were selected using a random sampling approach. Data collection methods included literature review, interviews, observations, and questionnaires. The results indicate that farmers' income sources within forest areas derive from managing HKm lands, primarily through the sale of non-timber forest products. Income sources outside the forest include employment as construction workers, traders, laborers, entrepreneurs, shop employees, motorcycle taxi drivers, and rice shop vendors. Income from within forest areas significantly outweighs that from outside forest areas, contributing IDR 32,830,793 (80%) compared to IDR 11,098,163 (20%). Welfare analysis revealed that 24% of respondents fall into the "very prosperous" category, while 76% are categorized as "prosperous".

Abstract

Protected forests play a critical role in biodiversity conservation and ecosystem stability but are often threatened by exploitation. Dalbergia latifolia (sonokeling) is a high-value species experiencing population decline due to overexploitation. This study aims to analyze the potential and distribution of sonokeling in the Sejorong Mataiyang Protected Forest Block, West Sumbawa Regency. Data were collected using the n-tree distance sampling method and vegetation analysis with the Importance Value Index (IVI) to measure density, frequency, and dominance. The results show that Dalbergia latifolia dominates across all vegetation levels (seedlings, saplings, poles, trees). At the seedling and sapling levels, plot 12 recorded the highest relative density (KR) and relative frequency (FR) values, both at 27.727%. At the pole level, the highest dominance (11.048%) was found in plot 5, while at the tree level, the highest dominance value (9.128%) was recorded in plot 9. These findings highlight sonokeling’s strong regeneration and adaptability to various environmental conditions. Sonokeling holds significant potential for conservation through ecosystem-based management and protection from overexploitation. This study provides a scientific basis for conservation efforts, supporting the sustainability of local ecosystems.
