Abstract

Desa Broto, Kecamatan Slahung, Kabupaten Ponorogo merupakan salah satu desa yang terletak di ujung paling selatan perbatasan antara Ponorogo dan Pacitan, Jawa Timur. Lokasinya yang berada di pegunungan dan jauh dari pusat kota menjadikan petani adalah mata pencaharian utama penduduk disana. Pada saat panen padi, untuk memisahkan biji padi dari sekamnya harus dijemur dan dikeringkan terlebih dahulu. Selama ini proses penjemuran beras dilakukan secara manual sehingga memakan banyak waktu dan tenaga. Selain itu,cuaca di pegunungan tidak menentu, terkadang sinar matahari tertutup kabut walaupun di musim panas, mengakibatkan proses pengeringan beras menjadi lebih lama. Oleh karena itu kami mengusulkan desain alat pengering beras dan produk pertanian lainnya dengan tenaga hybrid dan portable. Mesin pengering yang kami usulkan memiliki sumber energi dari listrik PLN maupun listrik dari tenaga surya. Dengan adanya penyimpanan energi dari tenaga surya ke dalam baterai, alat yang diusulkan menjadi mudah di mobilisasi ke area-area sawah tanpa perlu memikirkan sumber listrik. Melalui pemanfaatan mesin pengering bertenaga hybrid ini, hasil padi kering di Desa Broto menjadi 3-5% lebih banyak dibandingkan pengeringan cara manual dengan perhitungan seluruh hasil panen dan penambahan satu mesin tenaga hybrid.

Abstract

The DC-DC converter is used to convert the DC voltage, and the conversion is carried out to increase or decrease the voltage. This paper discusses the modeling of a boost converter for charging high-capacity capacitors using PID control. PID control is used to overcome changing voltages and long times to steady-state due to capacitor changes. The boost converter has a 24 V input voltage and a 350 V output voltage. Boost converter modeling is performed by electrically reviewing the circuit and then converting the differential equation from the electrical analysis into a state space that depicts the characteristics of boost converter. The simulation was performed using MATLAB software. For the initial conditions, a simulation was carried out using the calculated critical capacitor value to determine whether the boost converter output voltage reached 350 V. Furthermore, when the boost converter was replaced with a 4700 uF capacitor, the boost converter experienced underdamp oscillations with a settling time of up to 9 s. Therefore, PID control was used to overcome oscillations and long settling times. The Ziegler–Nichols 2 and Routh–Hurwitz stability methods were used to determine the parameters Kp, Ki, and Kd. From the calculation results, the parameters Kp = 0.6, Ki = 21.39, and Kd = 0.0042 are obtained. The output voltage response still has a high undershoot when using the parameters obtained from Ziegler–Nichols 2 tuning, but it already has a fast-settling time. By fine-tuning the PID control, the values Kp = 2, Ki = 90, and Kd = 0.09 were obtained. With these values, the boost converter voltage response has an overshoot of 388 V, an undershoot of 312 V, and a settling time of 0.6 s at 351 V.
