Abstract

This study aims to examine the properties of liquid fuel produced from the pyrolysis of two types of plastic waste: plastic buckets and plastic bags. The pyrolysis method is used to convert plastic waste into fuel oil (BBM) at high temperatures in the absence of oxygen. Experimental results show that 0.736 to 0.863 kg of fuel oil can be obtained from 1 kg of raw material. The color of the resulting fuel oil is influenced by the original color of the plastic material, indicating an effect of the chemical composition on the final product. Physical analysis shows that the density and kinematic viscosity of the fuel oil from plastic buckets are slightly lower than those of the fuel oil from plastic bags. However, both have values close to the characteristics of gasoline. The calorific value of the fuel oil from both types of plastic waste is still lower than that of gasoline and diesel, but sufficiently high for use as an alternative fuel. The ash and lead content in the pyrolysis fuel also remains below the maximum allowable limits for motor vehicle use. Thus, the fuel produced from plastic waste pyrolysis has the potential to be an environmentally friendly and sustainable alternative energy source.

Abstract

Community service program (PKM) aimed at raising awareness of the role of sprayer technology among the Sinar Harapan Farmers’ Group in Setanggor Village, Central Lombok Regency, has been successfully implemented. This PKM activity aims to improve the community’s understanding and ability to apply sprayer technology. The PKM was implemented in four stages: activity preparation, including identification and inventory; implementation of the PKM through outreach and practical training; and finally, evaluation and program sustainability. The results of this PKM indicate that the community is able to understand and apply sprayer technology to improve the efficiency of the rice spraying process for farmers. The results of the pre-test and post-test also showed a significant improvement, indicating that the partners—the Sinar Harapan farmer group in Setanggor Village, Central Lombok Regency—understand and are able to implement rice sprayer technology to achieve food self-sufficiency.
