Abstract

Fuel is an energy requirement that is needed by society. The increase in population is directly proportional to the consumption of fossil fuels. Therefore, one way to overcome the problem of fossil energy consumption is to develop alternative renewable energy sources. Potential renewable alternative energy is plantation and industrial waste, which currently has not been utilized optimally. Coffee is one of the most important commodities in the national economy. Apart from that, coffee has fans in terms of consumption. The amount of coffee consumed is directly proportional to the increase in coffee skin waste. Coffee skin itself has a high calorific value, so it is very good if processed into briquettes. This research aims to find out how to make briquettes using coffee skin waste. The research method used is a qualitative descriptive method with a focus on making briquettes from coffee skins. The data collection method is carried out by observation. The data that has been obtained is analyzed using descriptive methods. The tests carried out in this research included organoleptic tests, density tests, ash content tests, and combustion rate tests. Based on the tests that have been carried out, this research has succeeded in identifying the effectiveness of coffee husk briquettes as an alternative fuel in the context of utilizing coffee husk waste.

Abstract

The use of disposable styrofoam has become popular due to its practicality, but its use is harmful to health and the environment. Styrofoam, which is made from expanded polystyrene, contains harmful substances such as benzene and styrene, and takes millions of years to decompose and often leaves behind microplastics. As an alternative, making bio-styrofoam from bagasse and areca nut fronds can be an environmentally friendly solution. This research aims to make environmentally friendly bio-styrofoam by utilizing bagasse and areca nut fronds as an effort to reduce agricultural waste while reducing the use of plastic-based styrofoam, which has a negative impact on the environment. Bagasse contains 24% lignin, 53% cellulose, and 20% hemicellulose, while areca nut fronds contain 32% cellulose, 34% hemicellulose, and 17% lignin. Both materials have great potential in making bio-styrofoam. This research uses a qualitative descriptive method, data collection is done by observation and literature study. The results of the water absorption test amounted to 17.9%, the biodegradability test amounted to 50.7% within 2 weeks, and the tensile strength test amounted to 2.30N/mm2, the value has met SNI.

Abstract

Indonesia generates a large amount of rice-based agricultural residues, particularly rice husk, which contains lignocellulosic compounds and a calorific value of 13–15 MJ/kg, making it a potential alternative energy source. However, estimating biomass energy potential is challenged by uncertainties in production variability, residue ratios, calorific values, and conversion efficiency. To address this issue, this study aims to estimate the potential energy production from rice husk biomass as a contribution to Indonesia’s renewable energy transition within the 2025–2045 National Long-Term Development Plan (RPJPN). A stochastic Monte-Carlo simulation was applied using secondary data on national rice production, residue-to-product ratio, calorific value, and conversion efficiency. A total of 100,000 random iterations were conducted to obtain probabilistic estimates of energy potential. The results indicate that rice husk biomass can generate an average of 103.64 TWh, with a critical point of 40.04 TWh and an optimum value of 213.21 TWh. Compared to Indonesia’s projected 2045 electricity consumption, rice husk biomass contributes 10.34%–58.3% toward the RPJPN renewable energy target. These findings demonstrate that rice husk biomass holds significant potential to support national energy resilience and the transition toward a sustainable energy mix.
