Abstract

This article reports a failure analysis of a diesel generator set connecting rod type 3516 B that has operated for 79,678 hours. From visual observation, connecting rod cylinder #10 has changed color in the shank area. This phenomenon may represent many cases of generator failure, so an analysis to identify the root cause of the failure is needed for scientific literature. In this case, fault tree analysis, SEM-EDX, chemical composition, and microstructure testing were performed to obtain more comprehensive results. Through fault tree analysis, we found that the connecting rod damage was caused by compression leakage due to wear on the cylinder liner. Scanning Electron Microscopy (SEM) analysis shows that the piston rod material is discolored due to heat, namely the formation of iron oxide. The heat level received by the connecting rod is around 200 °C. We also found a finely formed, easy-to-clean scale where the thickness ranged from 0.00127–0.008 mm. Finally, EDX analysis showed high levels of iron (Fe) and oxygen (O) confirming that the formation of iron-oxide on the metal surface was due to the influence of heat.

Abstract

This case study was conducted in a manufacturing company that experienced a breakdown in a power generator set. A standard investigation was carried out by opening the crankcase cover and checking the dipstick. The results of the visual inspection showed that the engine oil was contaminated with water. Therefore, this study was conducted to further analyze the causes of oil contaminated with water in the unit being handled using fault tree analysis (FTA). As a result, cracks were found in the cylinder liner due to pitting on the outer liner with a pitting depth of more than 2 mm. In our analysis, pitting is formed due to the presence of air bubbles in the cooling system. Based on FTA, the formation of air bubbles is caused by the quality of the coolant. We also found that the coolant used was not added with any additives.

Abstract

The power transformer is an essential part of the electrical distribution system because it must be reliable and safe from fire and explosions, one of which is brought on by internal oil arching that results in overheating. In general, on the high voltage side of the transformer, there are power transformers fitted with tubular oil to oil cable boxes for the demands of the client. The tubular oil to oil cable box is installed to reduce space in substations with limited space as well as to boost safety against weather and pollution at the high voltage terminal section of power transformers. The goal of this investigation is to determine the cause of an explosion that occurred in a tubular oil-to-oil cable box on the high voltage side of a Gas Insulation System (GIS) type power transformer with a power of 60 MVA and a voltage rating of 150/20 kV. For all parties involved, this incident will serve as a lesson about what to avoid doing in the future with similar power transformers. In this study, we will use a qualitative method with Finite Element Analysis (FEA), which takes samples and data of a Gas Insulation System (GIS) power transformer on the high voltage side, especially in the analysis of tubular strength. This power transformer has a voltage rating of 150/20 kV and a power of 60 MVA. Applying normal pressure to a pressure that could harm the tubular oil to oil cable box can prevent damage. The tubular oil to oil cable box is built of SS400 material and has an 8mm thickness so that it can be determined how robust it is.

Abstract

Good management of organic and non-organic waste has an impact on comfort in residential areas and currently in the Cileungsi area, waste management has not been managed properly and has an adverse impact on the environment. As for housing, RT and RW environments, they are less active in terms of waste management. In the waste disposal process, each RT objected to the annual fee being increased. The fee charged for disposing of waste to the final shelter is around Rp. 12,500, - per head of family. It has been more or less 5 years since the levy fee has not been increased, due to the reason that the fee is used for other needs. Another problem also occurs in the Pesona Vista residential area, where garbage is collected by related parties, which takes 3-4 days each week. Under these conditions, discomfort arises in the environment, starting from the smell of garbage, because the rats eat the trash. The solution offered in this community service activity is organic and non-organic waste management to improve the economy of the community around the housing and create a healthy atmosphere in the housing environment. Organic waste will be managed to become liquid or solid compost. In the process of managing this organic waste using a counter, where there is a need for training on proper and correct operating and maintenance procedures. Meanwhile, plastic waste will be managed, to be sold to collectors
