Abstract

The combined cycle power plant must operate 24 hours without stopping so that in operation at any time an increase in the temperature of the gas generator RB211 can occur. The RB211 gas generator works well when the ambient temperature is low. The X combine cycle power plant uses a chiller to lower the inlet air temperature so that the air entering the compressor will be lower. The purpose of this study was to analyze and conclude the effect of the compressor inlet temperature on the thermal efficiency of the Rolls Royce RB211 gas generator in the combined cycle power plant. Data was collected by requesting historical data on September 5-11, 2022 in the central control room. The method used in this study is simple linear regression analysis because it only involves two variables. The independent variable is the inlet temperature of the compressor and the dependent variable is the thermal efficiency of the gas generator. It is known that the highest efficiency is at a temperature of 292,94 kelvin with a thermal efficiency value of 36,87% while the lowest efficiency is at a temperature of 301,89 kelvin with a thermal efficiency value of 35,61%. The regression analysis equation is Ŷ = 0,60665231-0,00082223X so the hypothesis results obtained through the significant F test with F table is that there is a significant effect between the compressor inlet temperature on the thermal efficiency of the gas generator.

Abstract

This research explores the 'pelakor' phenomenon, a term that describes women who have affairs with married men, in terms of Indonesian urban contemporary. This study focused on the downfall of social and relational norms, both in professional and personal space. Qualitative analyses were held between January and March 2025, with social media and news reports, interviews, and study literature. This research exposes the repeated norm-breaking in the school, workplace, and friendship environments. The cases exposed in this study show that individuals are purposely pursuing extramarital affairs due to financial motives and related career advancement. The findings show the deeper trend of exploitation of marriage and women's friendships to pursue affairs through planned emotional manipulations.Keywords: pelakor, extramarital affair,  infidelity, social media, tiktok, urban society, social boundaries

Abstract

This research is focused on making the trainer kit in the form of a device for measuring and calculating energy with an interactive practicum mode that is fun for students as part of the Thermodynamics course. This device will be equipped with a timer for measuring time, electrical mass measurement and a length calculator for measuring kinetic energy and potential energy using data on mass, velocity and height of an object. The data obtained from the measurement results will then be compared with the results of calculations on an application-based simulator in the visual basic .exe program.
