Abstract

Krisis energi di dunia sebagai akibat semakin menipisnya cadangan bahan bakar minyak khususnya dari bahan bakar fosil yang dimana bahan bakar jenis tersebut tidak dapat diperbaharui, Penelitian ini bertujuan untuk mengevaluasi pengaruh penambahan gas HHO terhadap performa mesin diesel. Penambahan gas HHO dalam proses pembakaran menunjukkan peningkatan kinerja mesin, yang terlihat dari penurunan konsumsi bahan bakar minyak. Pada beban yang meningkat (300- 1200 watt), daya, torsi, dan BMEP (Brake Mean Effective Pressure) mesin meningkat seiring dengan bertambahnya beban, dengan perbedaan daya, torsi, dan BMEP antara sistem bahan bakar tunggal dan ganda pada beban 1200 watt. Penggunaan gas HHO juga menurunkan FC (Fuel Consumption) dan SFC (Specific Fuel Consumption) pada sistem bahan bakar tunggal, dengan penurunan SFC hingga 15% saat jumlah gas HHO meningkat. Efisiensi thermal tertinggi dicapai dengan sistem bahan bakar tunggal, dan efisiensi thermal terjadi penurunan disaat ditambahkan gas HHO dengan variasi rendah, nilai efesiensi kembali naik seiring jumlah gas HHO yang ditambahkan semakin banyak.

Abstract

One of the most frequently used machine tools is lathe. Lathe parameters such as cutting speed and feeding motion determine the rate of material processing and the dimensions of the final result. The use of CMM provides advantages in dimensional measurement accuracy so that it can be used to evaluate the effect of cutting speed and feed motion on the lathe machining process. In this study, a product with an outside diameter of 62 mm and an inside diameter of 51.55 mm was used. The finishing process on the inner diameter becomes a diameter of 51.949 mm with a tolerance of ± 0.02. The amount of cutting speed used is 280 m/min, 340 m/min, and 440 m/min, as well as feeding motion of 0.1 mm/rev, 0.15 mm/rev, and 0.3 mm/rev. The results showed that variations in cutting speed and feeding motion can affect the diameter dimensions of the product. The measurement results tend to decrease from the standard with a value of 51.9467 mm to 51.9058 mm. The value of similarity from the largest with theory 99.9996% and actual 99.9978% to the smallest with theory 99.9986% and actual 99.9583%. The quality numbers range from IT 2 to IT 8 which means the use of modern machines (CNC) can be used well if the use of parameters is appropriate. The best combination to improve consistency and accuracy is 280 m/min cutting speed and 0.1 mm/rev feed motion. Keywords: lathe, CMM, diameter, accuracy, quality score

Abstract

Abstract Sampler Finish Mill 1 (Sampler FM1) is equipment that used to collect sample in cement production process in PT. Solusi Bangun Indonesia. During running time, Sampler FM1 usually got blocking in the material line about 8 times during 2023. When got blocking, the quality value of sample cement from Sampler FM1 can be different than sample from sample cement from Bucker Elevator (BE) that used to be reference value. This problem caused by the air that enter to the system in Sampler FM1 have high relative humidity value because Water Trap that installed in Sampel FM1 allegedly lacking. So, it needs observation and analysis condition of material line dan air at Sampler FM1 and the impact to the quality of cement at before and after installation new Water Trap at Sampler FM1. Depend on background problem that appear, so it needs observation and analysis about condition of material line dan air at Sampler FM1 and analysis comparison of cement quality between Sampler FM 1 and BE. When founded material line blocking, high relative humidity and deviation of cement quality, so it needs to install Water Trap again to solve this problem. Designed and installation new Water Trap by Maintenance Laboratory Team. After installation of new Water Trap, it needs to observation and analysis again about the condition of material line and air at Sampler FM1 and analysis about quality comparation between sample cement from Sampler FM1 and BE. Depend from observation, calculation and analysis additional amount of Water Trap at Sampler FM1, it can be concluding as follow: before installed additional Water Trap, condition of Sample FM1 often got blocking caused by air that entered to Sampler FM1 was too humid, this problem can be proved the value of relative humidity air at Sampler FM1 reached 88% and H2O value of cement sample more than 0.5%. When Sampler FM1 got blocking, quality of cement sample form Sample FM1 and Bucket Elevator is different during transition time of process production cement. This problem can be proving the value of SO3 contain, Blaine, Residue R45µm, and H2O is different. After installed a new Water Trap, condition of Sampler FM1 is unblocking after 2 weeks operational time because the air that entered in to Sampler FM1 become dry, it proves by Relative Humidity value of air at Sampler FM1 become 43% and H2O contains of cement sample from Sampler FM1 become less than 0.5%. After installation a new Water Trap, the condition of material way of Sampler FM1 become unblocking, so the quality cement between Sampler FM1 and BE become similar during transition time of process production cement.

Abstract

In the smelter industry, the reliability of heavy equipment such as slag haulers significantly impacts production continuity. Failure of this equipment can lead to high downtime and potentially significant losses. This study aims to improve the effectiveness of slag hauler maintenance by applying the Reliability-Centered Maintenance (RCM) and Failure Mode and Effect Analysis (FMEA) methods to the SH-001 unit.The study was conducted by collecting downtime data and component failure history from the maintenance team over a 3,600-hour operating period. RCM analysis was used to determine maintenance strategies based on function and failure consequences, while FMEA was used to identify failure modes and calculate the Risk Priority Number (RPN) as the basis for maintenance priorities. Reliability calculations were performed using an exponential distribution approach using the Mean Time To Failure (MTTF) and failure rate (λ) distribution.The results showed that the critical components causing downtime were the Fuel Injector Spring, Tensioner Bearing, and Cabin Cylinder O-Ring Seal, contributing more than 65% of the total downtime. The average reliability value for the SH-001 unit after 1,000 hours of operation was 66%. Based on the calculations, the optimal Preventive Maintenance (PM) interval for the Fuel Injector Spring was 1,819 hours, the Tensioner Bearing 1,271 hours, and the Cabin Cylinder O-Ring Seal 1,371 hours. The FMEA results showed the highest RPN values ​​for the Fuel Injector Spring (32), the Tensioner Bearing (24), and the cabin cylinder O-ring seal (16). The recommended RCM-based maintenance strategy covers three main categories: Scheduled Restoration Tasks for periodic replacement of major components, On-Condition Tasks for hydraulic system leak inspections, and Failure Finding Tasks for electrical component and protection system inspections. Implementing this strategy is expected to reduce downtime by up to 30%, increase equipment avalability above 90%, and reduce reactif maintenance costs by 20-25%. Keywords: Preventive Maintenance, Reliability Centered Maintenance (RCM), Failure Mode and Effect Analysis (FMEA), Reliability, Slag Hauler.

Abstract

Truck mounted crane is a tool used to move objects from one place to another within a limited operating range with the advantage of heavy load mobilization and cargo carrying capacity in one vehicle unit. The crane on the truck is equipped with long arms that can be extended or shortened automatically to adjust to needs, and can adjust the height by changing the elevation angle. This study examines the analysis of the strength of the crane boom in two scenarios of 8.178 meters and 5.478m using the finite element method. In each test scenario, four variations of elevation angles were carried out, namely, 90°, 100°, 110°, and 120°, and carried three variations of loads, namely, 2 tons, 2.5 tons, and 3 tons. In the first scenario with a length of 8.178 meters, the largest deformation was obtained when loading 3 tons and an elevation angle of 90°, the largest von misses value was obtained when loading 3 tons and an angle of 120°, and the largest safety factor was obtained when loading 2 tons and an angle of 90°. Meanwhile, in the second scenario with a crane boom length of 5.478 meters, the largest deformation was obtained when loading 3 tons and an angle of 90°, the largest von misses value was obtained when loading 3 tons and an angle of 120°, and the largest safety factor was obtained when loading 2 tons and an angle of 90°.
