Pemanfaatan Limbah Kulit Durian dan Limbah Kelapa Muda Menjadi Biobriket sebagai Sumber Energi Terbarukan

Abstract

The increase in durian production in Indonesia in 2021 by 19.40% and coconut production by 1.47% will be directly proportional to the increase in durian skin waste and young coconut waste produced. This waste has not been utilized optimally so that its availability is quite a lot in the environment. Both of these wastes contain large cellulose, namely 50% -60%. The element of cellulose will affect the carbon value so that with this content durian skin waste and young coconut waste can be used as raw material for making biobriquettes. This utilization is one of the efforts to utilize waste as a renewable energy source. This study aims to obtain the best characteristics of briquettes from a mixture of durian shell charcoal and young coconut charcoal according to the characteristics of briquettes in SNI 01-6235-2000, and to determine the economic value of briquettes. This research method was carried out experimentally, by mixing durian shell charcoal with young coconut charcoal as a raw material for briquettes in six variations namely (90%:10%), (75%:25%), (60%:40%) ), ( 45%:55%), (100% durian shell charcoal) and (100% young coconut charcoal). The results showed that sample 3 briquettes (60%:40%) were the best briquettes with the highest fixed carbon value (72.81%), calorific value (22,124J/gr or 5,284.23 cal/gr), moisture content (13. 83%), volatile content (1.69%), ash content (11.67%) and compressive strength (0.752 kgf/cm2). As well as the results of the SEM test showing the morphological structure of clean briquettes with tight cavities. The characteristics of the biobriquettes produced from the six sample brackets met the standards for volatile content and the calorific value of the briquettes, and the moisture content, ash content, fixed carbon content and compressive strength did not meet the characteristics of the briquettes according to SNI 01-6235-2000.
