Abstract

PT PLN (Persero) ULP Gianyar manages 29 feeders, one of which is the Monkey Forest feeder, distributing electricity to the Monkey Forest area, distributing electricity over an area of ​​7,168,10,232 m2 and a total cable length of 3.65 km supplied by the Payangan substation distributing electricity to 41 distribution substations in the Monkey Forest area with a total of 3,062 customers. Disturbances to the Monkey Forest feeder are dominated by animals because they are located in a tourist location which is a monkey habitat. The D-STAR innovation tool protects against interference caused by animals especially monkeys, in the construction of the stretcher pole at the meeting point/connection of the insulated aerial cable (SKUTM) with the SUTM conductor. Animal shields or what are usually called Cover Bushings are to protect distribution network components from interference caused by animals such as geckos that can easily reach electrical components. The effect of installing the D-STAR innovation tool (double tensile isolator) and animal shield on the SAIDI and SAIFI values ​​in the Monkey Forest feeder is very good, in 2023 the SAIDI value is 1.38 hours/customer/year and the SAIFI value is 1.31 times/customer/year where the value exceeds the target of PLN ULP Gianyar in 2024 after the installation of D-STAR and animal shield the SAIDI value is 0.01 hours/customer/year and the SAIFI value is 0.03 times/customer/year, the value has met the target of PLN ULP Gianyar and SPLN NO 68-2: 1986.

Abstract

Welding technology serves not only as a manufacturing process but also as a repair solution for all metal-based components. Spot welding is a welding method that utilizes electrical resistance to join various products made of sheet metal, in which the contacting metal surfaces are fused by the heat generated from electrical resistance. This welding method is selected due to several advantages, including ease of operation without requiring specialized skills as demanded by other welding techniques, as well as a faster process that enhances production time efficiency. Control of the electrical current path during welding is critical, as it significantly influences the characteristics of the joint, including weld quality, shear strength, hardness level, and resistance to external loads. This study focuses on analyzing the effect of electrical current in spot welding techniques on the shear strength of ST 42 steel plates. Through descriptive analysis and graphical representation, this research aims to observe the relationship between electrical current and the resulting shear strength produced by the welding process. The lowest average shear strength was recorded at an input current of 20.36 A with a welding output current of 6011.47 A, a welding time of 8 seconds, and a heat input of 61894.30 J, yielding a shear strength of 1.67 MPa. Meanwhile, the highest average shear strength was obtained at an input current of 28.95 A with a welding output current of 6011.47 A, a welding time of 8 seconds, and a heat input of 88007.92 J, resulting in a shear strength of 6.72 MPa. Electrical current control is therefore essential, as ST 42 steel plates experienced damage at an input current of 32.45 A and an output current of 6323.58 A, with a welding time of 8 seconds and a heat input of 98647.84 J.

Abstract

Spot welding is greatly influenced by the cooling medium in terms of welding characteristics such as strength. The tensile strength of ST 40 steel plate welded joints is influenced by the cooling medium and welding time. Testing and data collection use experimental methods on spot welding machines and shear tests. Data collection uses quantitative methods while processing uses descriptive methods. The ASTM E8 standard is used in sample testing. The flow of coolant fluid in the spotwelding process significantly affects the HAZ diameter. Faster fluid flow increases heat transfer from the electrode to the coolant, keeping the electrode and weld material temperatures below 1,500 ºC, thereby reducing electrode wear and maintaining a stable weld nugget size at 5.00 mm. The lowest HAZ diameter was recorded at a flow rate of 5 liters/minute with a HAZ diameter of 8.30 mm, while the highest was at a flow rate of 2 liters/minute with a diameter of 10.43 mm. Too fast cooling or too short welding time can cause brittle weld joints and reduce tensile stress. Conversely, slower cooling with appropriate welding time produces optimal tensile strength while maintaining the structural integrity of the joint. Optimal results were found at a fluid flow rate of 2 liters/minute at 5.0 seconds with a tensile stress of 96.10 MPa, 3 liters/minute at 6.0 seconds with a tensile stress of 104.89 MPa, 4 liters/minute at 7.0 seconds with a tensile stress of 114.00 MPa and 5 liters/minute at 8.0 and 9.0 seconds with tensile stress of 116.72 MPa and 125.76 MPa.

Abstract

Shoe drying is a crucial process for maintaining hygiene and extending the lifespan of footwear, especially in high-humidity environments. This study aims to experimentally investigate the heat transfer characteristics of a flat-rack-based shoe dryer. The system is designed with electric heating elements and a horizontal rack configuration to promote uniform heat distribution. Key observed parameters include inlet air temperature, shoe surface temperature, drying time, and moisture content reduction. Measurements were conducted at multiple rack levels to evaluate vertical and horizontal temperature distribution. The results indicate that forced convection is the dominant heat transfer mechanism, with relatively uniform temperature distribution observed in the middle racks, while the top and bottom racks experienced temperature deviations. The heat transfer by radiation generated by the shoe dryer is 5.41 J/s, and the convective heat transfer is 238.8 J/s. The moisture content loss increases with drying time, indicating that 90 minutes is the optimal drying duration among the tested variations. This study provides a foundation for the development of more energy-efficient shoe drying systems and highlights the potential for integrating alternative heat sources such as solar energy.

Abstract

The development of non-conventional light vehicle technology, such as the buggy car, demands efficient and reliable power transfer systems to support mobility in congested industrial areas. One of the primary technologies utilized is the continuously variable transmission (cvt), which offers the advantage of changing transmission ratios continuously without the interruptions found in conventional gear shifting. However, in its application, an imbalance often occurs between the engine speed (rpm engine) and the wheel speed (rpm wheel) due to load factors and power losses. This study aims to comprehensively analyze the correlation between rpm engine and wheel performance on a buggy vehicle under varying loads ranging from 3 kg to 8 kg. Experimental results indicate that increasing the load leads to a significant decrease in wheel rpm across all engine speed ranges; for instance, at 8000 rpm engine, the wheel rpm dropped from approximately 515 rpm (3 kg load) to 225 rpm (8 kg load). Conversely, wheel torque exhibited a linear increase as the load rose, reaching a peak value of 15.8 nm at an 8 kg load. effectiveness analysis shows that the output power (hp) tends to increase with the load, with the highest effectiveness achieved during lower engine speed operations (5500 rpm) at peak load. These findings provide a scientific contribution to understanding the mechanical behavior of cvts and serve as a technical reference for optimizing transmission tuning in light vehicles to achieve a balance between torque and power efficiency.
