Abstract

Nagori Sait Buttu is one of the tourist villages in Simalungun Regency, which offers natural beauty and agro-tourism. The problem faced in developing tourism in Sait buttu is waste management. The Simpatik Project Garbage Bank has been established for a long time, but its activities are only collecting waste and selling it. Through this community service, the community is trained to process the collected waste, namely organic waste and inorganic waste. Organic waste is processed into several products such as food and compost, while inorganic waste is processed into various crafts. Products are marketed online and offline. Communities are trained to market their products online by opening a shop on the Shopee application. Financial bookkeeping training was also carried out with the Android cashbook application. Currently, the Sympathetic Project Waste Bank already has various processed waste products that are marketed through Shopee and is able to record finances with the Android cashbook application. Through this service, the community through a sympathetic waste bank benefits by increasing income. Through the activities of the Sympathetic Waste Bank project, the environment is getting cleaner

Abstract

Excavators is one of the heavy equipment used to do transport, excavation, loading work that is operated using hydraulic energy. Excavator construction consists of three main parts, which consist of undercarriage, upper structure, and front attachment. During operation, one of the front attachment parts that has the highest performance is the boom cylinder actuator because it carries the entire load of the front attachment activity. The continuous work of the hydraulic boom cylinder will definitely suffer damage that cannot be avoided and can interfere with the performance of the unit. The damage is in the form of external leaks, internal leaks, scratches, and wear. This research aims to identify the types of damage, causal factors, and impacts caused by boom cylinder damage, explain the boom cylinder maintenance system and process, identify bends in the cylinder rod, and provide a reference price for repairing the Hitachi excavator boom cylinder. The methods used in this research are literature study, observation, and interviews. The results indicate that damage can be minimized by performing scheduled maintenance, such as selecting and replacing the right hydraulic oil and grease, cleaning the hydraulic oil cooler every 500 hours, replacing the oil filter every 250 hours according to the maintenance schedule, performing the inspection process during daily checks, operating the unit in the right way, avoiding modifications that can cause overloading, and performing oil analysis every 250 hours to ensure high availability of the unit as planned.
