Abstract

cylinder head is a part that is exposed to thermal and mechanical loads which not only affect engine performance parameters. The purpose of this study is to analyze the failure of the cylinder head structure of a 4 stroke diesel engine and find the cause of the failure. In this study, surveys and measurements of the cylinder head were carried out, to find out the appropriate results so that they could determine cracks, wear, and warping of the cylinder head. The results showed that the maximum bend on the side of the cylinder head attached to the cylinder block was 0.07 mm, 0.08 mm, 0.069mm. While the maximum bending on the side of the cylinder head attached to the manifold is 0.15 mm, 0.14 mm, 0.16 mm. At maximum bending on the side of the cylinder head attached to the exhaust manifold, it is necessary to pay attention to how to use the diesel engine correctly and according to operating hours.

Abstract

This study focuses on the management of gear pump maintenance on KM Kelimutu ship. Data collection methods are used to identify and investigate the causes of damage that occur in the gear pump. The required maintenance and repair actions are determined based on the analysis results. The process of managing maintenance involves several important steps. First, planning is carried out to determine the planned maintenance actions. Subsequently, organization is conducted by appointing responsible personnel and coordinating with relevant parties to minimize disruptions to the maintenance of equipment and other machinery on the ship. Furthermore, actuating involves efforts to ensure that all human resources work according to their tasks, functions, and competencies in order to achieve company goals. Finally, control is implemented through supervision of each job performed to identify and rectify any potential errors. The results of this study provide insights into the importance of gear pump maintenance and effective strategies in managing the maintenance process. By implementing the appropriate steps, it is expected to enhance the performance of the gear pump, extend its service life, and optimize operational efficiency in the industry.

Abstract

The Community Service Program (PKM) aims to improve production efficiency and product quality of the Mie Lidi Small and Medium Enterprises (SME) in Banjarsari Village, Sayung District, Demak Regency, through the application of renewable energy-based technology. The technology implemented includes solar panels with a hybrid inverter and an automatic drying system with temperature control. This technology reduces dependence on PLN electricity, ensures consistent product quality despite adverse weather conditions, and lowers operational costs. As a result, production capacity increased by 25%, and the sustainability of the SME's operations was better ensured. Additionally, technical training and managerial assistance were provided to support efficient and sustainable business management.
