The solar energy potential reaches 207.8 GWp in Indonesia, providing numerous opportunities to harness renewable energy. One approach is utilizing solar panels; however, these panels have a low energy conversion rate. Maximum Power Point Tracking (MPPT) is a technique that can maximize the performance of solar panels to consistently generate maximum power. Bisection MPPT is implemented in the system due to its ease of implementation, but it performs less effectively under low irradiance. The Incremental Conductance algorithm is a suitable choice for improving Bisection MPPT. Apart from being easy to implement, the Incremental Conductance algorithm is not dependent on the characteristics of the solar panel. It also features Variable Step Size to eliminate ripple when reaching the maximum power of the solar panel. Incremental Conductance MPPT can enhance Bisection MPPT with a maximum increase of 17,483 Watts. The Bisection-Incremental Conductance MPPT algorithm takes 2.122 seconds to reach the maximum power of the solar panel, generating 1.89 x 10^6 Ws of energy for 0.4 seconds. It yields the highest value compared to Bisection MPPT and Incremental Conductance MPPT.

Pada masa ini, penggunaan listrik sangat penting dalam kehidupan sehari-hari, namun kebutuhan energi tidak selalu dapat tercukupi. Sehingga sumber energi alternatif dapat menjadi salah satu alternatif dari sumber energi dari pemasok listrik negara atau PLN, dengan dasar demikian peneliti melakukan penelitian tentang sumber energi alternatif berupa sinar matahari. Panel surya digunakan untuk mengubah energi matahari menjadi energi listrik kemudian diolah oleh boost converter agar tegangan naik menjadi 28,8 Vdc sesuai dengan level tegangan baterai 24V/35Ah . Pengontrolan menggunakan mikrokontroller STM32F4 yang difungsikan untuk pengontrolan fuzzy, sehingga dapat menghasilkan daya maksimum dari tegangan boost converter yang memiliki efisiensi cukup bagus yaitu 86%. Dari hasil pengujian boost converter close loop bisa mendapatkan arus 6,89 A, tegangan 28,8 V dan daya 198,48 W. Simulasi yang dilakukan secara close loop maupun open loop sudah memiliki hasil yang sesuai dengan tegangan output dan arus output yang diharapkan.

ABSTRAKSuhu ruang penyimpanan Susu Bubuk akan mempengaruhi kualitasnya, dengan kemungkinan bakteri dan virus yang dapat mengkontaminasi produk, suhu yang direkomendasikan pada ruangan penyimpanan berdasarkan penelitian sebelumnya yaitu 20-25oC, dengan tujuan untuk menghambat pertumbuhan bakteri asam laktat. Berdasarkan permasalahan tersebut, dirancang ruang penyimpanan Susu Bubuk dengan kapasitas volume 220 liter dengan tidak menggunakan ventilasi melainkan ruang kedap udara, dengan menggunakan empat buah Peltier melalui pengaturan tegangan yang akan mempengaruhi temperatur. Pada saat menggunakan Peltier diperlukan tegangan yang sesuai dan konstan dari keluaran Buck Converter untuk mencapai suhu yang ditargetkan, sehingga digunakan kontrol Proportional Integral untuk mempercepat sistem ke tegangan yang diharapkan untuk suhu target 23oC. Pada hasil penerapan kontrol dengan Kp= 5 dan Ki= 22.32 pada tegangan 12 Volt didapatkan temperatur 23.2oC lebih mendekati suhu target dibandingkan dengan tegangan 11 volt dan 10 volt dengan suhu yang dihasilkan 23.5oC dan 23.8oC.Kata kunci: Buck Converter, Peltier, Proportional Integral, Susu BubukÂ ABSTRACTThe temperature of the Milk Powder storage room will affect its quality, with the possibility of bacteria and viruses that can contaminate the product, the recommended temperature for storage rooms based on previous research is 20-25oC, to inhibit the growth of lactic acid bacteria. Based on these problems, a powder milk storage room was designed with a volume capacity of 220 liters without using ventilation but in an airtight chamber, using four Peltiers through a voltage regulation that would affect the temperature. When using Peltier, an appropriate and constant voltage is required from the output of the Buck Converter to reach the target temperature, so that the Proportional Integral control is used to accelerate the system to the expected voltage for the target temperature ofÂ 23oC. In the results of applying control with Kp = 5 and Ki = 22.32 at 12 Volts, a temperature of 23.2oC is closer to the target temperature than the 11 volts and 10 volts with the resulting temperature being 23.5oC and 23.8oC.Keywords: Buck Converter, Peltier, Proportional Integral, Powder Milk

The use of solar panels is being pursued as a solution to reduce dependence on fossil fuels. However, solar panels face challenges such as power fluctuations due to environmental conditions and partial shading. To address these issues, an MPPT technique using Zebra Optimization Algorithm (ZOA) has been developed, which integrates foraging behaviour and defensive strategies to achieve GMPP. Simulation testing results show the superiority of ZOA over PSO in achieving GMPP. ZOA's contribution in addressing this problem is to efficiently perform a global search to find the optimal MPP, even under varying partial shading conditions. The algorithm mimics the behaviour of zebras in foraging and defending against predator attacks, enabling a fast solution search process and higher precision. ZOA can overcome the local maxima trap by expanding the search space, allowing solar panels to function close to optimal efficiency even if there is shading on a portion of the module. This improves system stability and performance and reduces energy loss due to partial shading. ZOA achieved a tracking accuracy of 99.99% with an average tracking time of 0.779 seconds and with a power gain of 28.5%, surpassing PSO with an accuracy of 95.18%, an average trcking time of 0.850 seconds with a power gain of 24.68%. In hardware testing, ZOA is also superior to PSO with an average tracking accuracy of 98.96% while PSO is 97.22%. These results underline the outstanding performance of the ZOA algorithm in optimising the power output of solar panels.

Utilization of electrical loads in predominantly inductive single-phase low-voltage power grids, the quality of electrical power becomes poor due to reactive power consumption resulting in a lack of power factor resulting in power loss, voltage drop, and decreased service life of the power grids. equipment. The research on reactive power compensation using TCR-FC aims to make improvements in improving the power factor in single-phase low-voltage electrical networks so that they have flexible control, do not experience excess compensation, have fast dynamic responses, and are space-saving. And can monitor voltage, current, and phase difference parameters through sensor readings to process data mathematically. When using electrical loads, the reactive power value is larger and the power factor is low below 0.85, the system controls the ignition angle of the TRIAC so that the current flowing into the reactor can be controlled by the reactive absorption measure of the fixed capacitor. So, it can improve the power factor. Simulation results can increase the power factor that exceeds the average value of 0.9 by 0.9797 with an error of 0.0288%. Hardware test results can increase the average power factor to exceed 0.9 by 0.9758 with an error of 0.1373%. in conclusion, reactive power compensation devices that use thyristor-controlled reactors and fixed capacitors can be more efficient than capacitor banks.

The development of technology today makes humans strive to save natural resources and switch to alternative energy. For reasons of saving energy, saving costs, easy to use, and having a high level of safety, induction heaters can be used as an alternative to overcome these problems. Induction heaters can generate heat through the process of electromagnetic induction when cookware made of metal is brought closer. In this process the coil is supplied with alternating electric current from a high frequency inverter which then induces the cookware with metal material to cause heat. The heat in the induction heater will be regulated through the switching frequency of the high-frequency inverter which gets its voltage source from a 24V battery and increases the voltage to 48V. This induction heater is designed to maintain the setpoint temperature 70°C and 100°C using fuzzy logic control. From the test results it can be seen that the fuzzy logic control can reach a setpoint temperature of 70°C within 20 minutes and after being disturbed the fuzzy logic control can maintain the setpoint temperature with an error percentage of around 0.14% - 0.29%. Meanwhile, the setpoint temperature of 100°C can be achieved within 35 minutes and after being disturbed the fuzzy logic control can maintain the setpoint temperature with an error percentage of around 0.14% -0.9%.
