Abstract

In the world and Indonesia, coal is one of the primary fuel sources for steam power plants (PLTU). This is due to the shrinking and increasing prices of fuel oil. With the abundance of coal energy sources, it continues to be used as the primary energy source for power plants in Indonesia. The economic efficiency obtained can reach 80% compared to the use of solar. However, Fly ash and Bottom ash (FABA), or solid waste produced from the coal combustion process at the PLTU, contains many inorganic minerals, which can pollute the environment, such as air and soil pollution. Conventionally, regarding economic law, Construction and Demolition (C and D) in the circulation system between materials and products must have zero material value and no longer produce residual waste in final disposal. This research implements Circular Economy (CE) to minimize the negative impact of FABA on the environment at PLTU. The experiment used FABA Coal as a mixed material to make Hollow Blocks with six combinations of sizes. The results obtained, the greater the percentage of FABA used, can minimize production costs and improve the quality of hollow blocks. From an economic cost analysis, using FABA for mixed materials for open block production will provide 55% greater economic benefits and 34.67% higher quality Hollow blocks compared to the composition of materials without FABA mixture.

Abstract

Work accidents in the construction industry are practically unavoidable, however they can be minimized. The aim of carrying out this community service is to socialize the importance of introducing occupational safety and health (K3) to protect and ensure the safety of every worker. Apart from that, it is also to increase safety and health awareness for workers in the construction projects and to increase awareness of the use of personal protective equipment for workers. Moreover, it is also to provide management recommendations for the layout of construction equipment and materials so as to create a safe working environment. The results showed that there was a significant increase between before the training and after training to the members for REI of South Sumatra. After the post-test was conducted in class, the community service activities was also integrated with lecture activities by inviting students to get involved in the construction projects.
