The main components of Home SPP are photovoltaic (PV) panels, inverters, and wiring systems. Given the strict price constraints, the selection of parts available on the commercial market is generally of low quality. However, low-quality components can still provide a significant advantage by optimizing the plant design. This research proves that the proper configuration can reduce electricity bills by 52.2%. This configuration does by choosing a Grid Tie Inverter (GTI) with a high working voltage and a 12 Volt PV configured in a parallel series circuit to work at 24 Volts. In addition, the 12 Volt PV panels configured in series to 24 Volts are proven to increase the conversion efficiency</p> Enangha Obeten Ntor, Adekunle Moshood Abioye ##submission.copyrightStatement## http://creativecommons.org/licenses/by-sa/4.0 https://ijatr.polban.ac.id/ijatr/article/view/106 Sat, 01 Oct 2022 00:00:00 +0000 Design and Build Automatic Cracker Machine Control System Based PLC-Pneumatic https://ijatr.polban.ac.id/ijatr/article/view/103 <p>Onion crackers are snacks categorized as crackers as complementary foods for the Indonesian people. Crackers are snacks that have a thin, round, and light shape. The process of packaging crackers is partially and fully manually done by humans. Packaging is representative of product quality. The packaging sealing process is influenced by pressure, temperature, and time. The method used in this study is to design and build a control system and test the results of the manufacture, where the control is made based on PLC with CX-Programer software which the system control integrated with HMI made with CX-Designer software. The control system is designed to drive the AC motor of the dosing system, the Dc motor of the packaging puller system, and the vertical and pneumatic heating system on the horizontal sealer system. The control system is made and tested for the function of the I / O program, and the overall control system that has been made works well.</p> Agus Sifa, Badruzzaman B, A.

The air conditioning system is considered one of the home appliances in which a massive amount of electrical energy is recorded, especially in the urban area. In this work, the fuzzy logic controller is designed to save energy for northeastern Nigeria using six and two input and output parameters respectively. The input parameters consist of the temperature of the user, temperature difference, number of occupants, time of the day, dew point temperature, and weather conditions. The output parameters consist of compressor speed and operation mode. The controller performance was simulated. The controller is designed in such a way that it can control the compressor speed leading to energy savings, and the operation mode to optimize humidity conditions, and when the room gets hot, it switches to air conditioning. The simulated result showed that a good percentage of electrical power could be saved when fuzzy logic is utilized</p> Maxwell Francis, Raji Luqman, Dadiyo Charles, Anjili Audu ##submission.copyrightStatement## http://creativecommons.org/licenses/by-sa/4.0 https://ijatr.polban.ac.id/ijatr/article/view/95 Sat, 01 Oct 2022 00:00:00 +0000 Battery-Supercapacitor Current Control Using Fuzzy Supervisory with PI Controller for Electric Vehicle Application https://ijatr.polban.ac.id/ijatr/article/view/82 <p>The configuration of the battery-supercapacitor as a hybrid power source (HPS) is one solution to overcome the limitations of battery life, such as in an electric vehicle. To achieve battery energy savings when a supercapacitor is added, a control scheme is needed. This paper proposes a battery-supercapacitor current sharing control scheme using Fuzzy Supervisory Control (FSC). The FSC is designed to determine how much current of the battery and supercapacitor need to discharge based on the current requirement of the load. The output of the FSC will produce a reference current which is then controlled in the main closed-loop control using a Proportional-Integral (PI) controller. The control signal in the form of a duty cycle is then used to regulate the battery-supercapacitor current through a DC/DC converter. This control scheme is tested using a resistive load change scenario both simulation and experimental. The results show that the battery-supercapacitor current can be controlled according to the loading conditions.</p> Adnan Rafi Al Tahtawi, Muhammad Reihan Iskandar, Sofian Yahya, Toto Tohir, Dedi Aming ##submission.copyrightStatement## http://creativecommons.org/licenses/by-sa/4.0 https://ijatr.polban.ac.id/ijatr/article/view/82 Sat, 01 Oct 2022 00:00:00 +0000 Biodiesel Production from Rubber Seed Oil as An Alternative Energy Source – A Review https://ijatr.polban.ac.id/ijatr/article/view/92 <p>Biodiesel is one of alternative energies that can be used to overcome problem caused by limited amount of fossil fuels reserved. Biodiesel can be made from rubber seed oil that has high potencies in Indonesia. The availability of rubber seed is quite much with more than 3-million-hectare rubber plantation area. The production of biodiesel from rubber seed oil has been carried out by several researchers using various methods. Therefore, this study was conducted as a review to obtain optimum operation conditions and effect of antioxidant addition in biodiesel production. Production methods of biodiesel from rubber seed oil observed in this study are esterification-transesterification, one stage transesterification, and in situ transesterification methods. Types of antioxidant added to biodiesel from rubber seed oil observed are TBHQ, D-TBHQ, BHA, BHT, PG, and OG. Esterification-transesterification was chosen as the most effective method in producing biodiesel with a minimum yield of 96.4%. Antioxidant addition of TBHQ with 1000 × 10-6 (ω) dosage was selected as the most effective to increase biodiesel induction period to become 6.41 hours, fulfilling the SNI 7182-2015 standard, which is minimum of 6 hours. Standard used as the reference for observing biodiesel parameters is SNI 7182-2015.</p> Herawati Budiastuti, Nira Aulia Hanifah, Devita Utami Mardiani, Haryadi Haryadi, Rusdianasari Rusdianasari, Ahmad Fudholi ##submission.copyrightStatement## http://creativecommons.org/licenses/by-sa/4.0 https://ijatr.polban.ac.id/ijatr/article/view/92 Sat, 01 Oct 2022 00:00:00 +0000 Optimization of Device Installations in the Home Solar Power Generation System https://ijatr.polban.ac.id/ijatr/article/view/80 <p>One of the main challenges in building a Solar Power Generation System at home or a Home Solar Power Plant (Home SPP) is choosing component specifications according to price.

This research created a new model to forecast DHSR for the Mubi metropolitan area in Adamawa State, Nigeria. Data for this study were obtained from the National Aeronautics and Space Administration (NASA) over a 22-year period (2000 – 2021). When DHSR was employed as an output, the requested values were air temperature (Tai) and relative humidity (Rhi). The MATHLAB curve fitting program was used to create the new DHSR mathematical model. The model was validated using five statistical methods in this study: MSE (mean square error); SSE (sum of square errors); RMSE, Chi-square error (X2), and the absolute fraction of variance (R2) are 0.0005, 0.0064, 0.0231, 0.0011kWh/m2/day, and 0.9998, respectively.</p> Luqman Raji, Maxwell Francis, A K Issa ##submission.copyrightStatement## http://creativecommons.org/licenses/by-sa/4.0 https://ijatr.polban.ac.id/ijatr/article/view/108 Thu, 03 Nov 2022 14:19:59 +0000
