Abstract
Dalam menyikapi ketersediaan sumber energi fosil yang terbatas di alam perlu upaya serius dan berkesinambungan untuk mengembangkan sumber energi terbarukan, salah satunya yaitu energi matahari. Energi ini tersedia secara gratis, ramah lingkungan, serta cocok dengan kondisi wilayah di Indonesia. Dalam penelitian ini dikembangkan rangkaian DC-DC buck converter yang digunakan pada prototipe sistem penyimpanan daya listrik panel surya menggunakan Maximum Power Point Tracker (MPPT) dengan algoritma hill climbing. Pada rangkaian DC-DC buck converter menggunakan lowpass filter Butterworth orde 2 dengan frekuensi cut-off sebesar 1000 Hz untuk meminimalisir adanya ripple pada keluaran buck converter yang dapat mempengaruhi kualitas keluaran serta efisiensi prototipe. Pada prototipe ditambahkan sistem feedback yang bertujuan untuk mengendalikan tegangan keluaran berdasarkan selisih tegangan keluaran yang terbaca dengan tegangan referensi. Prototipe dilengkapi dengan sensor arus, tegangan, dan sensor lingkungan yaitu sensor suhu dan intensitas cahaya. Data yang didapatkan tersimpan secara otomatis ke dalam sdCard secara realtime. Selain itu Arduino UNO R3 digunakan sebagai pengendali sistem MPPT. Sensor perlu dilakukan karakterisasi sebelum digunakan. Pada proses karakterisasi sensor didapati kesalahan relatif pengukuran pada sensor tegangan DC A dan B sebesar 0,97% dan 0,85%, sensor arus INA219 A dan B sebesar 0,71% dan 1,05%, sensor intensitas cahaya GY-49 MAX44009 sebesar 5,43%, sensor suhu DS18B20 sebesar 0,18%. Proses karakterisasi juga dilakukan pada sistem MPPT, didapati bahwa rentang kerja duty cycle pada sistem MPPT dari 0% hingga 90% dengan tegangan masukan panel surya sebesar 13 hingga 22 V. Untuk menghasilkan tegangan keluaran yang stabil pada nilai 12 V, prototipe membutuhkan waktu 15 hingga 20 detik. Prototipe yang telah dikembangkan mampu menghasilkan rata-rata daya listrik sebesar 964,49 mW dengan nilai rata-rata efisiensi sebesar 52,04%. ************************************************************ In responding to the limited availability of fossil energy sources in nature, serious and continuous efforts are needed to develop renewable energy sources, one of which is solar energy.. This energy is available for free, environmentally friendly, and suitable for regional conditions in Indonesia. In this study, a DC-DC buck converter circuit was developed which was used in a prototype solar panel electrical power storage system using the Maximum Power Point Tracker (MPPT) with a hill climbing algorithm. In the DC-DC buck converter circuit, a low pass filter Butterworth 2nd order with a cutoff frequency of 1000 Hz is used to minimize ripple at the output of the buck converter which can affect the quality of the output and the efficiency of the prototype. In the prototype, a feedback system is added which aims to control the output voltage based on the difference in the output voltage that is read with the reference voltage. The prototype is equipped with current sensors, voltage sensors, and environmental sensors, namely temperature and light intensity sensors. The data obtained will be automatically saved to the SDCard in real time. In addition, Arduino UNO R3 is used as a controller for the MPPT system. Sensors need to be characterized before use. In the sensor characterization process, it was found that the relative errors of measurement on DC voltage sensors A and B were 0.97% and 0.85%, current sensors INA219 A and B were 0.71% and 1.05%, light intensity sensors GY-49 MAX44009 by 5.43%, DS18B20 temperature sensor by 0.18%. The characterization process was also carried out on the MPPT system, it was found that the duty cycle working range of the MPPT system was from 0% to 90% with a solar panel input voltage of 13 to 22 V. To produce a stable output voltage at a value of 12 V, the prototype took 15 to 20 seconds. The prototype that has been developed is able to produce an average electric power of 964.49 mW with an average efficiency value of 52.04%.
