Abstract

Agricultural biomass such as cocoa husks and peanut shells have great potential as raw materials for briquettes to support the provision of sustainable alternative energy. This study aims to evaluate the effect of variations in the composition of these two materials on the characteristics of briquettes, including calorific value, moisture content, ash content, and burning time. The study was conducted using a completely randomized design (CRD) with five treatment compositions (KC1=100:0, KC2=70:30, KC3=50:50, KC4=30:70, KC5=0:100) and three replications. Data were analyzed using Analysis of Variance (ANOVA), and if significant effects were found, the analysis was continued with Duncan’s Multiple Range Test (DMRT) at the 5% level. The results showed that a high proportion of cocoa husk resulted in higher moisture content (15.78%) and lower calorific value (3867 kcal/g), while a high proportion of peanut husk increased the calorific value to 5340 kcal/g and burning time to 84.8 minutes, but was accompanied by higher ash content (17.57%). The balanced mixture of KC3 (50:50) and KC4 (30:70) proved to offer the best compromise, with moisture content <10%, calorific value >4400 kcal/g, burning time >78 minutes, and ash content still within an acceptable range. Thus, although pure peanut shell briquettes (KC5) offer the highest performance, the combination of KC3 and KC4 is more worthy of consideration for improving briquette quality while optimizing the utilization of abundant cocoa shell waste.

Abstract

Kertasari Village is one of the villages in Labuhan Haji Subdistrict, East Lombok Regency, whose main economic base is in the agriculture and fisheries sectors. Despite its rich potential in dry land and agricultural/cash crop production, the village community faces serious challenges in the form of high poverty rates and health issues, particularly stunting and malnutrition among pregnant women. This situation is exacerbated by the suboptimal utilization and processing of agricultural products to meet families' nutritional needs sustainably. The University of Mataram's Community Service Program (KKN PMD) focuses on interventions based on the optimization of local resources. The aim is to reduce poverty rates, stunting, and early marriage by maximizing agricultural products for the nutritional needs of pregnant women, infants, and children. This is achieved through the optimization of agricultural/cash crop processing into value-added food sources by creating innovative products. The program aims to create smart farmers and a healthy generation by maximizing the potential of agricultural products, thereby realizing an independent and stunting-free Kertasari Village.
