Abstract

In oil and gas industry activities, the oil and gas processing process will produce waste, one of which is oil solid waste, which is waste that comes from the production and processing process of petroleum in the oil field because it is one of the supports for the Cepu refinery which has several old wells that are still actively producing to this day, thus the use of waste oil is very necessary. With the amount of TPH obtained from waste oil, which is 48.10%, there is potential to be extracted. The method used is a simple heating method to separate hydrocarbons from waste solids. After the extraction test was carried out and associated with the results of the oil composition test, the saturated composition was obtained 48.84%, aromatic 23.59%, resin 25.91% and asphaltene 1.66% where this composition has an influence on the results of the hydrocarbon extraction test from waste oil. With simple heating using an oven, the results obtained are not significant as the extracted oil hardens again. After heating, the light fraction of saturated oil is released while the heavy fraction, resin and aromatics, as well as impurities, affect the hardening of the sample at room temperature.

Abstract

Workover and well service activities are routine activities to repair and maintain production wells, such as replacing oil pump equipment and changing well hole reservoir parameters such as drilling and cracking activities This is done to repair and maintain wells so that they can always produce according to the specified potential However, during the work, the production of each well that requires repair must be temporarily stopped until the well is repaired. The length of time a well is not producing depends on the length of the repair of the well. Therefore, drilling performance must be evaluated to avoid delays in well production in the long term. Based on the results of this study, the PDSI# 35.1/IDECO H-35-M rig has a performance level of 88% for 15 days; the performance presentation of the rig is good. In addition, from the results of the NPT using a Pareto diagram, there are several main problems that cause rig performance, namely, waiting for a bright day, waiting for equipment repair time, inspection/safety checklist, and waiting for licensing time.Keywords: Rig Operational Performance.

Abstract

The effect of additives such as seashells (containing CaCO₃) and nani wood charcoal on the mechanical properties of steel during the carburizing process is significant. The addition of CaCO₃ acts as a catalyst, accelerating carbon diffusion into the steel's microstructure, thereby increasing surface hardness and flexural strength. The results showed that increasing the percentage of CaCO₃ up to a certain point can increase the hardness and strength of the steel, with the highest hardness value achieved at a variation of 50% CaCO₃ and 50% nani wood charcoal, at approximately 21.93 HRC. Hardness testing showed that the variation of additives directly affected the final hardness, with the highest value being achieved at the optimal combination of CaCO₃ and nani wood charcoal. In addition to hardness, other mechanical properties, such as bending strength, also showed an increasing trend with increasing CaCO₃ proportions up to the optimal point, namely at a variation of 70% CaCO₃ and 30% nani wood charcoal, which resulted in a bending stress of 32.64 MPa and a bending strength of 3336.14 MPa. Therefore, the adjustment of the proportion of additives is a key factor in optimizing the mechanical properties of steel through the carburizing process enriched with these natural materials. Keywords: seashells, nani wood charcoal, catalyst, a bending strength

Abstract

This study aims to analyze the effect of varying paint and thinner mixtures and the number of coats applied on the adhesion and hardness of car paint. The research method used was experimental, varying the paint:thinner ratio (100:110, 100:120, 100:130, and 100:140) and the number of coats applied (2 and 3). Adhesion testing was performed using a Cross-Cut Adhesion Tester, while hardness testing was performed using a Shore D Durometer. The results showed that a paint:thinner ratio of 100:130 provided optimal results for both tested parameters. In the adhesion test, the 100:130 ratio achieved level 5B (best) with no paint peeling, while in the hardness test, it reached the highest value of 88.77 HD. Excessive addition of thinner (ratio 100:140) resulted in a decrease in quality, with adhesion decreasing to level 3B and hardness dropping to 83.3 HD. Variations in the number of coats showed that using two coats provided more consistent results than three coats, especially in terms of adhesion. This study concluded that an optimal balance between paint and thinner is crucial for achieving good paint quality, with a 100:130 ratio providing the best results for automotive body painting applications.

Abstract

Automatic motorcycles are a type of motorcycle equipped with an automatic transmission system that does not require a manual gear lever for shifting. The gear ratio changes automatically according to the engine speed, allowing the rider to control acceleration solely by adjusting the throttle. The use of an automatic transmission, or Continuous Variable Transmission (CVT), in this system relies on a standard V-belt, as it significantly affects engine performance. However, some motorcycle owners use non-standard belts because they are cheaper, which often leads to faster wear. This study was conducted to determine the wear rate experienced by both standard and non-standard belts after a certain period of use under specific operating conditions. The method used to evaluate belt wear rated an experimental approach, in which the motorcycle was operated at an average speed of 40 km/h over a distance of 24 km for three hours per day, over a period of three months (12 weeks). Each week consisted of 5 days of testing, with the first 6 weeks allocated for the standard belt and the following 6 weeks for the non-standard belt. After the testing period, the belts were removed and their wear was measured. The measurements were compared to the initial data to determine the amount of wear that had occurred. The results showed that the standard belt, after 6 weeks of use (90 hours), experienced wear of: 0.10 mm in diameter, 0.72 mm in upper width, and 0.25 mm in lower width. Meanwhile, the non-standard belt exhibited wear of 0.31 mm in diameter, 0.92 mm in upper width, and 0.78 mm in lower width. Based on these findings, using a standard belt is preferable, as it does not wear as quickly as a non-standard belt. Keywords: automatic motorcycle, V-belt, wear rated.

Abstract

Carbon steel is a type of alloy steel consisting of various elements, especially iron (Fe) and carbon (C). In general, the properties of steel are affected by the percentage of carbon and the microstructure of steel which is affected by steel composition and heat treatment. The welding process can change the structure and composition of steel. The safety of weld results can be carried out after welding using a heat treatment process. This tempering aims to obtain better and desired mechanical properties. Tempering is carried out using temperatures of 200⁰C, 250⁰C and 300⁰C with cooling using air media and mechanical testing will be carried out.The results of this research showed that tempering temperature had an effect on the hardness value of medium carbon steel resulting from FCAW welding. The hardness value at a temperature of 200℃ was 54.75, a temperature of 250℃ was 53.00 and a temperature of 300℃ was 52.04. The higher the temperature, the lower the hardness value and conversely, the lower the tempering temperature, the higher the hardness value.Keywords: Welding, Tempering, Hardness
