Abstract

CNC machine is a machine tool whose entire operation is controlled using a computer by inputting N and G codes. There are 2 types of programming for CNC lathes, namely incremental (the starting point of the program can change or the program endpoint becomes the beginning point of the next program), absolute (the starting point becomes the fixed reference point of the program. The study aimed to determine the low surface roughness value of S45C carbon steel with feeding motion variations of 0.15 mm, 0.25 mm, and 0.35 mm with a cutting depth of 0.4 mm and a constant spindle rotation speed. The insert used is branded iscar with a radius of 0.8 mm.. The lowest roughness value at feeding motion of 0.15 mm belongs to the roughness class, namely N7. The intermediate roughness value at feeding motion of 0.25 mm belongs to the roughness class N7. While the highest roughness value in feeding motion (feeding) 0.35 mm is included in the roughness class, namely N8. The average value results are obtained from the testing process using a roughness test tool (stylus).. The effect of feeding motion on the results of the surface roughness of S45C carbon steel in the CNC process is that the smaller the feeding value, the lower the roughness value produced, while the greater the feeding value, the higher the roughness value produced.

Abstract

The function of the generator is to produce electrical energy from the mechanical energy that rotates it. However, in a system for the generation of electrical energy, there are possibilities for interference with the generator which can cause the generator to suffer damage. One of the disturbances that often occurs in generators is short circuit faults. Short circuit disturbances in generators can be caused by various things, which is an example of an insulation failure in the stator winding is called Partial Discharge. The failure of the insulation that occurs in the stator winding is the most dominant cause of damage to the generator. However, in operation, many factors cause a decrease in the quality of the insulation of the stator winding, including pressure factors that are electrical, mechanical and thermal. Partial discharge in the generator stator winding can also cause power losses in the generator. Power loss occurs due to the control of electric charge within a certain time frame during the partial discharge activity. By using the formula calculation, the value of the power loss that occurs due to partial discharge can be identified and analyzed to determine the condition of the generator. Partial discharge measurements were carried out using the IRIS POWER TGA-BTM Portale Partial Discharge (PD) Monitoring tool and the PDLitePro software. The object of study is the North Duri Cogeneration Generator Unit 1. Based on the results of comparative analysis, the measured PD magnitude was 160 mV in the isolation of the generator stator winding Unit-1 Phase A, 134 mV in the isolation of the generator stator winding Unit-2 Phase B and 124 mV in the isolation of the generator stator winding Unit-3 Phase C entered into Typical PD category level (<75 % Summary of Statistics). In addition, the generator Unit-1 has the highest magnitude when compared to Unit-2 (134 mV) and Unit-3 (124 mV). However, in general, PD activity in Unit-1 winding isolation is still within safe limits up to 160 mV. The value of the power loss due to a significant partial discharge that occurred in the North Duri Cogeneration Plant generator was in phase A of all phases that occurred and occurred on March 25 2019 with a power loss value of 8.70 mW.

Abstract

PT XYZ is a subsidiary from one of the largest fertilizer companies in Indonesia which was only formed at the end of 2022 which was previously a compartment of its parent company. PT XYZ has several departments under it starting from the maintenance department, fabrication department, engineering and business department and also the ALBER (Heavy Equipment) department. Because it is a newly established company and with the addition of several new units, an OHS policy is needed for the safety of the company's work activities. Especially for the mobile crane units. The Hazard ldentification, Risk Assessment, and Risk ControI (HIRARC) procedure was apIicated in this study to minimaIized any kind of risk. Using the Job Safety AnaIysis (JSA) method at the Hazard ldentification stage in this study. The risks to the hazards that have been identified wiII be counted based  on likeIihood and severity, which wiII determine the Ievel of risk. Based on the risk assessment, potential hazards are categorized into 4 levels, namely low risk, medium risk, high risk and extreme risk. In carrying out the mobile crane rental business process activities, 11 work activities with low and medium risk were found. What is highlighted in this business process is the process of operating a mobile crane where almost all activities carried out by operating a mobile crane have a risk with the highest severity value. Given the high risks that exist in the process of operating a mobile crane, updates and controls must be carried out frequently. Because  if you not improve tooIs and work activity the danger will be increased. It is necessary to socialize the application of K3 policies regularly and continuousIy from the beginning to the end of the business process.
