Abstract

On February 18, 2023, an incident occurred at Tuban Plant factory. Namely a work accident that happened to a senior employee from the Fire & Rescue division. This incident occurred in a restricted area where evacuation access was limited and there was no telephone signal because it was located underground. Therefore, the author decided to make and install a safety device in the form of a temperature or heat detector and material level to provide warnings in the form of danger lights and sounds from horns in the area. After the tool is installed, temperature monitoring can be done on the local panel and also from the Technical Information System (TIS). After installation, from HIRAC calculations this tool succeeded in reducing the risk score by 95%, from initially 360 (high) to 18 (low). Apart from that, this tool can also save IDR 39,974,495 per hour from the initial handling time before the tool was 66.3 hours.

Abstract

In the welding process, the parts to be welded receive local heat, thermal expansion occurs, even though the cold parts do not change, this causes structural stress and structural changes can occur. Therefore, the choice of electrode type significantly influences the tensile and bending stresses as well as changes in structural content. Based on the analysis carried out, the E6013 type electrode has the lowest tensile stress value, namely 455.8707 N/mm². Meanwhile, the highest average tensile stress on the E7016 type electrode reached a tensile value of 561.47535 N/mm². The highest Bending Stress value was 162.95 (N/mm²) for the E7016 electrode and 155.85 (N/mm²) for the E6013 electrode. and in the E6013 microstructure element the carbon C content is 6.92% and in the E7016 sample the carbon C element content is 3.61%. A low hydrogen content really prevents oxidation during welding, because when steel has a high oxygen content, the tensile stress and yield when moving during welding will be reduced.

Abstract

Surabaya is the capital city of East Java province, which has a large area of ± 335.28 km², with a population of 2,972,801 (2022). Surabaya as a big city has public street lighting (PSL) from 2017 to 2023 amounting to 557,512 points. To facilitate the monitoring of PSL throughout the Surabaya area, the Surabaya Transportation Agency Government plans to build a PSL monitoring room which will be allocated in the Surabaya Intelligent Transport System (SITS) building which is located on the 2nd floor close to the ATCS monitoring room so that it is centralised. In achieving the plan, it is necessary to analyse the power requirements of the SITS building before and after the addition of PSL monitoring room by comparing the capacity of the existing generator. SITS building power before the addition of PSL monitoring room is 47.366 kW, while the power requirement after the addition of PSL monitoring room is 58.609 kW. Generator power of 110 kW is greater so it does not require additional generator capacity. Keywords: PSL, Traffic Light, SITS

Abstract

Brake Cooling Duct is a useful technology to drain air from the front so that the brake caliper & brake disc do not overheat. Another benefit is to keep the engine temperature normal because the it always gets fresh air. This study adds an air duct design or brake cooling duct to cool the brake disc using ANSYS CFD simulation with speeds of 48 Km/h and 98 Km/h to get the temperature of the brake disc when braking without cooling duct and using brake cooling duct, the difference in heat flux value after adding air duct/brake cooling duct, the process of temperature changes that occur when the air flow from the brake cooling duct touches the surface of the brake disc with speeds of 48 Km/h and 96 Km/h. The results obtained brake disc temperature when braking without cooling duct with a maximum temperature value of 137.74 ºC and using brake cooling duct with air inlet speed of 48 Km/h is a maximum of 74.73ºc and 98 Km/h is 73.42 ºc. There is a difference in heat flux value after adding an air duct / brake cooling duct of 33116 W/m2 with a speed of 48 Km/h and 33746 W/m2 with a speed of 96 Km/h. The temperature change that occurs when the air flow from the brake cooling duct touches the surface of the brake disc with a speed of 48 Km/h is 58.97º C, for a speed of 96 Km/h is 60.26º C.

Abstract

Cement Mill is the place where the final grinding process of cement. Cement Mill at Tuban Factory uses the type of Vertical Roller Cement Mill which is a product from Loesche. One important parameter to note is vibration. High vibrational speeds can damage equipment so it must be limited referring to the manual book from Loesche, which must not exceed 16 mm / s. Therefore, it is necessary to add a pruftechnik vibration sensor program to the Distributed Control System (DCS) cement mill as a safety device. Then after conducting literature studies, continued with concept design and program creation in ABB Control Builder M software using computers for Engineering in factories using function block diagram (FBD) programming language. The result of the program is an additional safety device for cement mills in the form of an interlock system that automatically turns off the cement mill motor drive when the vibration speed value is read beyond 16 mm / s. Apart from being a safety device, the addition of this program also produces real-time monitoring system facilities In the form of an indication of vibration speed along with a graph that can be accessed online, making it easier for operators to find out the vibration value without having to check in the area.

Abstract

The Kiln Feed System is a main system in clinker production. This system functions to weigh and convey Kiln Feed materials from the Blending silo (391-3S1) to the Preheater for the initial burning process. At PT Solusi Bangun Indonesia, the Kiln Feed System utilizes Pfister Feeder equipment (431-PF1). However, this machine frequently experiences failures, posing a risk of production losses in clinker manufacturing. According to data extracted from the Technical Information System (TIS), over the past 5 years, the kiln at PT Solusi Bangun Indonesia's Tuban plant has stopped 13 times, with each stop lasting an average of 90.47 hours. To address this issue, it has develop a new system that can serve as a backup Kiln Feed. This would involve designing a modification program for the Proportional Gate 431-PG2 to act as a backup Kiln Feed. This modification aims to prevent kiln shutdowns due to failures in the Pfister Feeder, which serves as the primary material feeding system for Kiln Feed at PT Solusi Bangun Indonesia Tbk.

Abstract

The Diesel Power Plant (PLTD) on Gili Iyang Island is the only power plant on the island with a capacity of 1,220 kVA, operating in an isolated system or not connected to other power plants. The current peak load is 416 kW, and is supplied by 3 units: Unit 1 of 656 kW, Unit 2 of 160 kW, and Unit 3 of 160 kW. Therefore, if there is a disruption in Unit 1, it leads to rotational blackouts. By observing the number of customers and the consumption of diesel fuel in relation to the energy generated by the diesel engines, the ideal power and operational pattern that can enhance the reliability of the PLTD can be determined. The current contracted number of customers is 1792, with a total power of 1894 kVA, assuming a load factor of 65% and a safety factor of 120%, the ideal PLTD power is obtained as 1500 kVA. In determining the operational pattern, it is divided into 4 patterns considering the generator's load. Patterns 1 to 3 utilize the composition of the existing 3 engines, while Pattern 4 involves an additional engine. Considering the reliability of the generator's operation, Pattern 4 is the most effective with a fuel requirement of 1,599.86 liters per day at a cost of IDR. 2,879.69/kWh
