Abstract

Fuse Cut Out (FCO) is a separation device in medium voltage networks, FCO removal is done by separating the top contact with the fuse carrier. How to remove the fuse carrier in general still uses a manual method with special equipment, namely a 20KV telescopic stick. The use of telescopic sticks is very time consuming and prone to leakage of insulation which affects work safety. In this study, the release of the fuse carrier was carried out with a remote control as a command to release and enter the fuse carrier.  Testing of this tool is carried out at a voltage of 223 Volts AC. The remote control design is able to provide a command signal with a maximum distance of 21 m in real time conditions. The mechanical construction is adapted to the standard clearance distance in the medium voltage network and the results of mechanical manufacturing of the upper contact with the fuse carrier release distance of 207 mm and the upper contact with the pneumatic actuator of 200 m, the compressed air source uses 5bar. The average success was 88.8% Phase R, 77.7% Phase S, 77.7% Phase T. The construction of the fuse carrier drive tool in this study is used in the release of FCO so that release and entry require faster time and optimise work safety.

Abstract

Based on PLN standards regulated in Minister of Energy and Mineral Resources Regulation No. 20 of 2020, changes in voltage on the network must be maintained within the voltage variation range of ±5% (Normal Voltage). Voltage is the change in voltage variations in a short time. Where the voltage change exceeds or below the standard voltage variation range, namely ±5% of the normal voltage. Based on IEEE Standard 1159-1995, the sag voltage is in the range of 10% -90% of the nominal voltage which lasts for 0.5 cycles. The voltage wave is in the range of 120% of the nominal voltage. Changes in voltage variations are caused by many factors such as large motor starting currents, uncontrolled load changes and short circuit current disturbances in the electric power system. The importance of maintaining voltage is a necessity because it is related to the reliability of an electric power system. For this reason, this research proposes "Application of the Fast Fourier Transform Method to Monitor Voltage Fluctuations" as a solution to power quality problems. To make it easier to process voltage (sinusoidal), the Fast Fourier Transform (FFT) method is needed. The FFT method algorithm is needed to convert the time domain into the frequency domain, so that it can simplify the monitoring system process. This research was implemented the FFT method for monitoring voltage fluctuations in no-load and load conditions. From the results, it can be concluded that inductive loads can affect voltage quality. This was proven when carrying out tests under load, from the results of the analysis there was a decrease in voltage (voltage SAG) of 10% (Vrms = 209.5 V; time duration 0.1436 s) and an increase in voltage (voltage swell) of 20.6% ( Vrms = 278.75 V; time duration 0.228 – 0.428 s).

Abstract

One of the agricultural problems in Indonesia is the rice field mouse pest. The problem is that controlling rat pests is done with chemicals that are not good for the rice field ecosystem, so it is necessary to prevent them by controlling rat pests that are more environmentally friendly, such as using ultrasonic waves. The rat repellent tool uses a NodeMCU ESP32 microcontroller with a PIR sensor to detect the presence of rats. The expulsion method uses ultrasonic waves which cause uncomfortable conditions for rat pests. The tool designed also uses an energy source from sunlight. The 50wp solar cell functions to convert sunlight energy into electrical energy. Then, energy is stored in the battery via the charger controller. The voltage produced by solar panels varies depending on the intensity of sunlight received with a maximum voltage of 22V. The PIR sensor can detect at a maximum distance of 8m at a beamwidth of 45°.

Abstract

Coconut milk is an essential ingredient in daily life. To obtain coconut milk, the coconut flesh must be grated and squeezed from its shell. To enhance the grating process, a coconut grater machine is necessary. However, existing coconut grater machines have been less effective in terms of operational efficiency. Therefore, an idea emerged to improve the efficiency of the coconut grater machine by incorporating a ball-joint mechanism for clamping. This redesigned coconut grater machine utilizes a slider with a ball-joint mechanism on the clamping side, allowing movement along three axes (x, y, and z). This mechanism enables more effective clamping of the coconut shell with shorter clamping time. As a result, the grating capacity increases to 47.01 kg/hour, representing a significant improvement of 1510% compared to the previous coconut grater machine.

Abstract

In the current test, leaks really need to be carried out at GIS Simpang. This test was carried out by strengthening the 20 kV incoming cable in the GIS Simpang 150/20 kV transformer bay. The impact of measuring this leakage current is to reduce the occurrence of leakage currents so that they are not too severe because this can determine how much the leakage current increases in the incoming cable. The trend test results were measured to determine the comparison between the leakage current in January and the leakage current measurement process at GIS Simpang. Based on the results of leakage current testing on transformer 1 and transformer 2 incoming 20 kV cables from several phases, it shows that the results of the leakage current trend in the cables have not increased significantly. However, from the calculation results listed, it can be seen from the comparison table that the results have increased during the calculation and have slight differences compared to the leakage current measurement results themselves. This is because from the calculation results, the cable temperature detection experienced a slight increase in the cable temperature as measured by thermovision to determine the thermal failure voltage. However, the cable is still suitable for operation because the temperature of the cable itself has a standard that does not exceed 150C for several measured cable phases.

Abstract

Welding is a technique for joining metals by melting a portion of the base metal and filler metal, with or without additional metal, to produce a continuous metal joint. The aim of this research is to determine the effect of electrode composition from three brands, namely Niko Steel, Atlantic, and Kobelco, on tensile strength, bending, and impact. This study uses SMAW welding with a single V butt joint in the 1G/PA position on SS 400 steel plates, using 4.0 mm diameter electrodes. The welding results are then inspected visually and with a NDT penetrant test to ensure conformity with TWI acceptance standards. Subsequently, the workpieces are cut with a bandsaw into specimens according to ASTM E8 for tensile testing, ASTM E290 for bending testing, and ASTM E23 for impact testing. The research results show that the highest tensile test value is achieved with Niko Steel electrodes, having an average tensile strength of 792.5 MPa. In bending tests, the highest bending strength is also observed with Niko Steel electrodes, averaging 8.71kN. In impact testing, the highest average value is found with Niko Steel electrodes, at 1.1 J/mm².

Abstract

Indoor farming requires a substitute for sunlight for its growth, therefore a system was created to control the light intensity used for indoor farming using the BH1750 Sensor which has an accuracy level of 94.6% and an AC Light Dimmer as a PWM Module. It is important to remember that AC Light Dimmers regulate light intensity by cutting off some of the sinusoidal waves from the AC electric current, and this can produce side effects such as noise or electromagnetic interference (EMI) in electrical lines. In the noise conducted emission test on the AC Light Dimmer, a noise value of 80.33dBµV was obtained, which is far from the CISPR 22 Class B standard value, so a passive EMI filter with the Low Pass Filter (LPF) type was designed to be able to reduce the conducted emission noise. The passive EMI filter designed and tested has an effective dampening response even though there is a shift in the cut-off frequency of 28.7KHz from that obtained in the calculations. The Passive EMI Filter designed is capable of reducing noise conducted emissions produced by AC Light dimmers by 80.33dBµV to 26.46dBµV and produces excellent attenuation of up to 53.87dB and meets the specified standards (CISPR22 Class B).

Abstract

PT. Tata Metal Lestari (PT. TML) is a company that produces zinc aluminum coated steel and zinc coated steel used for raw materials for mild steel and other construction products. The machine used in the production process of PT. TML uses a lot of large 3-phase AC motorcycles. Because these motors require a very strict maintenance process by measuring and recording the vibration and temperature of the drive motor every day. ATMI Industrial Polytechnic (Polin ATMI) in collaboration with PT. TML jointly developed a tool that aims to collect motorcycle condition data quickly and provide direct warnings to the maintenance team if there are abnormal conditions. The analysis and design method used in this study succeeded in making a vibration and temperature monitoring system tool for non-portable engines that can detect vibration and temperature on the motor using a non-portable network that can be displayed on a screen so that it can help PT. TML. The tool made has a size of 70 x 70 x 40 mm which makes this tool small in size and is designed to be installed in all conditions and positions according to the request of PT. TML, the test results of the vibration value of the prototype have a result of 2% greater while the temperature is 1.5% greater than the value on the measuring instrument.
