Abstract

Garbage is a problem that is still ongoing today. Based on data from the Ministry of Environment of the Republic of Indonesia, there is the province of Central Java as the highest waste generation in 2022. Therefore, it is necessary to have waste management activities so that they do not have an impact on the environment. One of the community groups that has carried out this activity is the Real Berkah Garbage Bank group located in Pandes Village, Wedi District, Klaten Regency, Central Java Province. The group has been processing organic waste and inorganic waste. However, the management stopped, because one part of the waste processing machine was permanently damaged. So there is a need for a new engine replacement. To prevent this from happening again, community service activities are also needed to increase the level of public understanding in theory and practice. The method used in this community service activity is the lecture method and the practical method. Through this community service activity, there was an increase in the level of understanding of the lecture method by 80% and an increase in the level of understanding of the practical method by 55%.

Abstract

To create briquettes, the raw materials are compressed using a variety of pressing pressures. Briquette presses come in two popular varieties: vertical and horizontal. Briquettes are often made from non-hazardous home waste and agricultural biomass, offering a premium and sustainable alternative energy source. The goal of this study was to use a hydraulic press-type briquette press method to improve the shape properties of the briquettes. The ingredients employed in this investigation were water, tapioca, wood dust, and rice husk. The composition of the briquettes is 40% rice husk, 40% sawdust, 10% tapioca, and 10% water. A hydraulic press machine with a maximum pressure of 30 Psi was utilized in the briquette press method. This study will examine each mold's density, drop test, water resistance, and burning rate. According to this study, triangular briquettes have the lowest briquette burning rate value (0.1 g/min), the lowest impact resistance value (0.67%), the slowest burning rate value (0.1 g/min), which indicates longer burning, and the highest value (0.9696 g/cm³), which indicates a denser and more solid structure. According to the findings of the test criteria that researchers have conducted, triangular briquettes are recommended.
