Abstract

Piping is a tool that functions to drain fluid from one place to another. The problem at Factory X is the failure of the boiler pipe. Pipe failures that occur are known by indications of leaks in the boiler. The initial process of a failure in an ordinary pipe is characterized by corrosion. The problem of corrosion in boilers is usually caused by feed water or feed water which still contains high oxygen levels. The purpose of the research is to determine the microstructure of the boiler pipe after experiencing the combustion process in the combustion chamber. This research method is an analysis of the chemical composition of boiler pipe material, Visual / Macro and Micro Testing. From the results of the inspection, observation, it can be concluded, the cause of pipe damage on the outside of the fire side caused by erosion corrosion is classified as very severe because it is beyond the optimum thickness of the pipe. Specimen A which is a material that has not received heat treatment has a microstructure, where the condition of the fearlite area is greater than specimen B with heat treatment.

Abstract

Boilers operate at high pressure and high temperature. When the life of the boiler pipe reaches its limit, failure will occur. High temperatures on the outside of the pipe, high pressure inside, and also flames that have been contaminated with corrosive residues for a long amount of time will cause pipe failure. The purpose of the study was to identify the hardness value of boiler pipes after experiencing the heating process and without heating on ASTM A179 pipes. The research method carried out is starting from the preparation of tools and materials, cutting small materials (making specimens), hardness testing, data processing, data analysis and drawing conclusions. The research results are as follows: 1) Obtained average hardness values on standard ASTM A179 pipes in boilers with each brinell, Rockwell, and Vickerss test of 63.67 HRB, 45.20 HRC, and 85.20 HV. 2). The average hardness value of ASTM A179 pipes affected by boiler combustion chamber temperature with each brinell, Rockwell, and Vickerss test is 76 HRB, 50.40 HRC, and 202.30 HV. 3) The value of hardness test results on standard ASTM A179 pipes comparing with after heating has increased hardness in each brinell test by 63.67: 76 HRB, Rockwell by 24.20: 50.40 HRC, and Vickerss of 85.20: 202.30 HV.

Abstract

This research focuses on the design of a solar energy demonstrator with a 35-degree tilted panel configuration, as well as testing its performance in orientation towards sunrise and sunset in real environmental conditions. The evaluation was conducted to analyze the effect of tilt angle and orientation on the efficiency of the solar panel system. The tests were conducted for five days (October 07-12) between 8 a.m. and 4 p.m. The maximum power was achieved at 10 a.m. and 10 p.m., respectively. Maximum power was achieved from 10:00 to 12:00, with a peak of 70 watts on October 07, indicating optimal conditions for sunlight absorption. In contrast, the power generated in the morning (08.00-09.00) and afternoon (15.00-16.00) was lower, ranging from 10-30 watts, due to lower solar intensity. In terms of efficiency, the highest peak reached 50% at 10:00 to 12:00 on October 07, while in the morning and afternoon, the efficiency decreased to 10-20%. The difference between days was influenced by weather conditions, with October 07 and 08 having higher power and efficiency. This research shows the importance of tilt angle, orientation, time of day, and weather conditions in determining the optimal performance of solar panels.

Abstract

Abstract: This community service activity was motivated by the drying problems of emping melinjo in Perbaungan District, Serdang Bedagai Regency, which still relies on sunlight. This traditional method has many limitations as it depends on weather conditions, requires 2–3 days, and produces products that are less hygienic and inconsistent in quality. The purpose of this activity is to provide a solution through mentoring and training in the use of the electric emping melinjo dryer (KEPINGJO) so that partners are able to operate the equipment and increase production capacity. The implementation method includes several stages: preparation, technology socialization, training, trials, evaluation, and mentoring. The results show that the partners actively participated and were able to operate the equipment independently. The use of the electric dryer resulted in a reduction from 1 kg to 0.64 kg within 1 hour at a temperature of 55 °C, which is much faster than the traditional drying method that takes 2–3 days. In addition, the moisture content of emping melinjo, initially 29% in the wet condition, decreased to 9.5% after the drying process using the electric dryer. The final product is more hygienic, evenly dried, and has a longer shelf life. The application of the KEPINGJO electric dryer has proven to increase productivity, product quality, and household income while strengthening the role of universities in delivering appropriate technological innovations.
