Abstract

Biomass-based renewable energy development is a strategic solution to address the energy crisis and environmental degradation. The gamal plant (Gliricidia sepium) has high potential as a biomass source due to its rapid growth, adaptability to marginal land, and role in increasing soil fertility in agroforestry systems. This study aims to formulate a model for developing a gamal biomass-based agroindustry as a renewable energy source within a sustainable agroforestry framework. The method used is a literature study with a critical analysis and synthesis approach to various relevant studies. The results of the study indicate that gamal biomass has high energy conversion potential through technologies such as biopellets and biogas that are efficient and applicable. This is evident from the analysis of the review results conducted on 15 articles that have gone through a screening process to be used as scientific literature material in this study. Integration of gamal biomass into agro-industrial systems can create economic added value, improve local energy security, and support environmental sustainability by reducing carbon emissions. The novelty of this study lies in the development of a conceptual model that integrates biomass production, energy conversion technology, and sustainability dimensions in a single agroforestry-based agro-industrial system. These findings provide a strategic contribution to the development of locally resource-based renewable energy and strengthening the rural economy.

Abstract

This study aimed to analyze the relationship among agroforestry stand production, value creation, and farmers’ welfare in Madayin Village, Sambelia District, East Lombok Regency. A mixed-methods approach was employed, involving 10 purposively selected farmers and five agroforestry land units. Data were collected through field observations, stand measurements, interviews, and questionnaires, and were analyzed using descriptive statistics, percentage analysis, and thematic analysis. The results showed mean stand volumes of 4.02 m³ for white teak (Gmelina arborea), 2.00 m³ for teak (Tectona grandis), and 4.18 m³ for mahogany (Swietenia mahagoni). Interview and questionnaire findings indicated that farmers perceived agroforestry as generating economic benefits through enterprise diversification and more efficient land use, social benefits through cooperation and livelihood security, and environmental benefits through land conservation and the maintenance of vegetation cover. The quantitative and qualitative findings were integrated to formulate the Agroforestry Value Creation Model, a conceptual framework linking stand production with economic, social, and environmental value creation and farmers’ welfare. These findings highlight the potential of agroforestry to support the strengthening of local value chains, although their interpretation is limited to the case-study context of Madayin Village.
