Abstract

This study aim to analyze the effect of the mass and diameter of the waste valve on the efficiency of hydraulic pumps. This study method was an experiment on the specimens and analyzing the mathematical equations contained in the hydraulic pump theory. The data measured in this study were the flow of water in, discharge of wastewater, and discharge of water out. Independent variables in this study were the mass of the waste valve, namely 1.5 kg, 2.0 kg, 2.5 kg, 3.0 kg and the diameter of the waste valve was 2.0 inches, 2.25 inches, and 2.50 inches. While the dependent variable were the discharge and efficiency of the hydraulic pump. The results show that the mass of the waste valve and the diameter of the waste valve affected the efficiency of the hydraulic pump. The highest efficiency of the hydraulic pump occurred at a waste valve mass of 1.5 kg and a waste valve diameter of 2.5 inches which was 78.08%, and the lowest efficiency occurred at a mass of 3.0 kg waste valve and a 2.0-inch diameter of a waste valve which was 33. 56%.

Abstract

This community service aims to improve the understanding and basic skills of the community in Hewuli Village, Sikka Regency, in maintaining and carrying out minor repairs to motor vehicles. This activity is part of the implementation of the Diagnostic Strategy course, which integrates theory with direct practice in the field. The training focuses on early identification of vehicle problems, periodic maintenance steps, and handling minor damage that often occurs. The methods used in this activity include interactive lectures, demonstrations, and direct practice by participants. The results of the activity show an increase in the knowledge and technical skills of the community in carrying out minor services independently. This activity is expected to encourage independence and provide added economic value to the local community through applicable technical skills.

Abstract

Watugong Village, located in Alok Timur District, Sikka Regency, is a traditional agricultural area where maize serves as both a staple crop and an integral part of local cultural heritage. However, post-harvest processing—particularly the shelling of maize kernels from the cob—is still conducted manually, leading to inefficiency and reduced grain quality. Attempts at mechanization through modern machines have often proven unsuitable due to their high cost, complexity, and incompatibility with the needs of small-scale farmers. To address this issue, the Mechanical Engineering Department of Politeknik Cristo Re developed a 20 kg-capacity maize shelling machine that is ergonomic, affordable, and easy to operate. Powered by a 0.75 kW electric motor, the machine employs a transmission system comprising pulleys, V-belts, and a silent chain, enabling it to increase shelling efficiency by more than 4.5 times compared to manual methods. Performance tests show a shelling capacity of up to 400 kg/hour with minimal kernel damage. The novelty of this machine lies in its participatory design approach and use of locally available materials and components. This innovation serves as a tangible example of appropriate technology grounded in local wisdom, supporting improved productivity, farmer self-reliance, and sustainable food security in rural communities.

Abstract

This research analyzes the effect of three oil brands, namely MPX1, Federal Ultratec, and Enduro 4T on engine operating temperature and fuel consumption on the Honda Revo Fit 110 cc PGM-FI motorbike. The test was carried out at an engine speed of 17,000 rpm for 30 minutes using Pertalite fuel. The parameters observed include engine temperature and remaining fuel volume. The results show that the type of oil influences thermal performance and fuel efficiency. MPX1 oil produces the highest temperature of 111°C with the most economical fuel consumption (968 ml remaining). The Federal Ultratec showed a temperature of 109°C with 900 ml remaining, while the Enduro 4T had a low of 107°C with 880 ml remaining. MPX1 with the semi-synthetic SAE 10W-30 formulation has better viscosity stability than the other two mineral oils, so it is able to maintain combustion efficiency and engine performance. Overall, the MPX1 provides the most optimal performance, the Federal Ultratec excels in engine protection at high loads, and the Enduro 4T is better in lowering operating temperatures. Choosing oil that matches engine specifications is an important factor in maintaining fuel efficiency and engine durability.
