Abstract

Juanda International Airport is the number 2 busiest airport with a total of 4,316,508 service users in 2022 (BPS, 2022). The increase in the number of service users along with the easing of air travel requirements can cause frequent complaints from service users regarding the air temperature that is felt to be uncomfortable in the terminal area. Given the importance of the existence of a passenger departure terminal, the availability of facilities according to service standards is also a point that needs to be considered. The intended service standard includes departure and arrival facilities at a terminal which includes services for prospective passengers and passengers at the airport terminal. One of the facilities considered in the departure and arrival process is air conditioning (PM 178 2015) and ASHARAE. The author here performs calculations and analysis of cooling loads in the Terminal 2 Building on floors 1 and 2 covering 26 areas.

Abstract

Currently most of the marine fishing in Indonesia uses traditional boats with navigation systems using compasses and mobile phones. Besides being ineffective, this fishing system also has a high risk, so a safer fishing system is needed, namely using an autonomous boat with a system capable of attracting fish. The use of the Autonomous Surface Vehicle (ASV) for monitoring and fishing purposes has been carried out by Aryusmal (2018) [1] , namely using GPS equipped with an Arduino Uno microcontroller to carry out ship movements, and an error of 1.5 m was obtained. Whereas Permana (2018) [2] made an ASV ship with GPS equipped with an APM microcontroller and Arduino Uno, an error of 30 cm was obtained. Referring to the need for a safe fish system and the results of previous research, this paper designed an autonomous ship with a GPS navigation system using a pixhawk microcontroller which is supported by the use of a brushless motor as the main propulsion of the ship and mission planner software to determine navigation waypoints. This system is able to monitor in real time and save the results of navigation and compass movements up to the last waypoint on the Pixhawk microcontroller. To find out the performance of the ASV, waypoint latitude and longitude tests were carried out on a laboratory and field scale. Laboratory test results have an error of 1.7%, while the results of field testing error errors that occur are 4.4% at longitude and the smallest error is 1.3% at latitude. This error occurred due to field conditions due to sea water shocks. However, this error did not really affect the movement of the ASV ship, because the shift was not too far.

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%.

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. It proves by SO3 contain, Blaine and Residue R45µm is similar, but H2O contain of cement from Sampler FM1 is still higher than Bucket Elevator. Key words: Sampler FM1, Water Trap, Cement Quality.
