Abstract

A transformer is a static electric device that is used to change the alternating voltage to a higher or lower level and is used to transfer energy from one electric circuit to another without changing the frequency. When the transformer is working, there is a temperature rise in the transformer which affects the degradation of the insulating paper and transformer oil. This accelerated aging tester applies the drying and vacuuming process as well as the arrangement of paper insulation racks to achieve maximum test results. The research method refers to IEC 60216-3 2006 for aging time, IEC TS 62332-1 2014 and IEC TS 62332-1 2011 as a reference for the Development of Accelerated Aging Experimental Test Cells for Transformer Oil-immersed Paper Insulation Systems. After achieving the existing goals, the addition of the drying process resulted in quite good Breakdown Voltage test results, not only that after the addition of vacuum it produced a good oil color according to ASTM D1500 as well as after the presence of paper placement racks the results of good tensile strength testing were proven by a graph which relatively decreased from sample 1 to sample 3.

Abstract

A transformer is a static device that can transfer electrical energy using the principle of electromagnetic induction. In operating conditions, the increase of temperature in the transformer will cause the oil insulation having disturbance, which will cause the quality of the insulation to decrease. In this research, oil isolation type shell diala b was chosen which was placed in an accelerated thermal aging chamber experiment device. Then shell diala b oil insulation is heated to a temperature of 120 °C and 160 °C with three sampling times. After this, the oil insulation characteristics were tested which includes oil color scale testing and UV-Visible spectrophotometric testing of the oil. The research method used refers to the IEC 60216-3 2006 standard for aging time and ASTM D-1500 COLOR SCALE for color scale testing. After testing the characteristics of shell diala b oil insulation, it was found that the value of the color scale had increased. Besides that, there has been an increase in the absorption of UV-Visible rays within the oil insulation, which causes the color of the insulation become darker as the temperature and the aging duration in the accelerated thermal aging chamber increases.

Abstract

The use of electrical energy plays a vital role in supporting the continuity of production processes in industrial environments. One critical area that heavily relies on electrical power supply is in the planning of installing a capacitor bank with a detuned reactor. The primary objective of this planning is to enhance the power factor (cos φ) from 60% to 85.2% during full-load operations and up to 94% when operating as per demand simulations. The evaluation of power quality from the implementation of the Capacitor with Detuned Reactor is conducted through simulations using ETAP 12.6.0 software.The simulation results from ETAP 12.6.0 produce comparative graphs between buses equipped with the Capacitor with Detuned Reactor and buses without it, both during full-load operational conditions and when only operating in simulations. The information derived from the simulation provides a deeper insight into the impact of installing the capacitor with detuned reactor on power factor and power quality within this industrial environment. With this understanding, further steps can be taken to optimize the electrical power system within the industrial setting.

Abstract

Smallholder goat farmers in Jabung Village, Malang Regency, face significant challenges related to manual milking, including prolonged labor time and limited access to appropriate technologies. This study aimed to evaluate the effectiveness of a portable, battery-powered milking device in enhancing labor efficiency, technical knowledge, and economic outcomes for these farmers. Using a Participatory Action Research (PAR) approach, the research involved 50 farmers through a baseline survey, co-design process, a six-hour training session, and follow-up evaluation. The results showed that the device reduced the average milking time for five goats from 64 ± 4 minutes to 55 ± 3 minutes, indicating a 14% improvement. Farmers’ technical knowledge also increased significantly, from 42% to 85% after training. User satisfaction was high, averaging 4.2 out of 5, with women reporting greater ergonomic benefits. Economically, the device demonstrated an eight-month payback period based on a milk price of 12,000 Indonesian Rupiah per liter. Furthermore, 80% of farmers were able to operate the device independently after training. These findings suggest that the device holds strong potential to improve smallholder productivity and resilience, contributing to Sustainable Development Goals (SDGs) 2 and 7. However, limitations include the small sample size and the absence of data on milk quality, indicating the need for broader, long-term research.

Abstract

In various industrial applications, the use of a power supply that uses a conventional diode single-phase rectifier topology results in high harmonic values in the electricity distribution system. One of the real impacts of this harmonic value is the heating of the electric power system equipment and power losses. High rms current values due to harmonics often cause problems in protection settings in addition to efficiency problems. The percentage value between the total harmonic component and the fundamental component is called THD (Total Harmonic Distortions). Therefore, in this study an asynchronous dcdc boost converter is connected to the output side of a singlephase diode rectifier which is capable of improving power factor and low harmonics. So that a THD value of less than 15%, PF (Power Factor) = 0.92-1 and a sinusoidal input current can be obtained. The implementation results show that the PFC (Power Factor Correction) method can work well on single-phase diode rectifiers.
