Abstract
Pupuk merupakan media sumber nutrisi tanaman pertanian, memiliki dua jenis yaitu organik dan anorganik. Penggunaan pupuk organik dianjurkan bagi tanaman karena mengandung lebih dari satu unsur hara sehingga dapat mengurangi masalah kondisi tanah dan pencemaran lingkungan dari penggunaan pupuk anorganik. Pupuk organik yang beredar di masyarakat berupa pupuk organik padat dan pupuk organik cair (POC). POC merupakan pupuk berupa larutan dari pembusukan limbah organik oleh aktivitas mikroorganisme melalui proses fermentasi, fermentasi dibagi menjadi dua metode yaitu anaerob dan aerob. Dalam proses fermentasi beberapa parameter yang penting agar proses fermentasi dapat berjalan dengan baik sehingga dapat menghasilkan produk akhir yang diinginkan salah satunya adalah temperatur. Sehingga temperatur yang dikontrol memberikan lingkungan hidup yang baik untuk mikroorganisme sehingga dapat mempercepat waktu fermentasi. Oleh karena itu pada proyek Tugas Akhir ini sistem kontrol temperatur pada fermentor POC menggunakan sensor temperatur RTD PT-100 dengan eror pembacaan sebesar 0.89% dan keakuratan pembacaan sebesar 99.11% sebagai alat ukur, serta PID kontrol untuk mengatur tegangan ke heater agar input tegangan stabil ke heater sehingga menghasilkan output temperatur yang stabil sesuai setpoint 40℃ dalam fermentor untuk mengoptimalkan waktu pembuatan POC. Nilai parameter PI yang digunakan yaitu Kp = 102,880288, nilai Ki = 1,872423115, dan nilai Kd = 0. Dengan parameter tersebut dapat mencapai setpoint dari temperatur awal 30℃ hingga 40℃ dengan rise time selama 4 detik, nilai maximum overshoot sebesar 0detik, nilai delay time sebesar 16,5detik, dan nilai error stady state 0 detik

Fertilizer is a source of nutrients for agricultural and has two types: organic and inorganic. The use of organic fertilizer is recommended for plants because it contains more than one nutrient so that it can reduce soil condition problems and environmental pollution from the use of inorganic fertilizers. Organic fertilizers circulating in the community are solid organic fertilizer and liquid organic fertilizer (POC). POC is a fertilizer in the form of a solution from the decay of organic waste by the activity of microorganisms through a fermentation process. Fermentation is divided into two methods, namely anaerobic and aerobic. In the fermentation process, several parameters are important so that the fermentation process can run well so that it can produce the desired final product, one of which is temperature. So that the controlled temperature provides a good living environment for microorganisms so that it can accelerate the fermentation time. Therefore, in this Final Project, the temperature control system in the POC fermenter uses an RTD PT-100 temperature sensor with a reading error of 0.89% and a reading accuracy of 99.11% as a measuring instrument, and PID control to regulate the voltage to the heater so that the voltage input is stable to the heater so as to produce a stable temperature output according to the 40 ℃ setpoint in the fermenter to optimize the POC making time. The PI parameter values used are Kp = 102.880288, Ki value = 1.872423115, and Kd value = 0. With these parameters, it can reach the setpoint from the initial temperature of 30 ℃ to 40 ℃ with a rise time of 4 seconds, a maximum overshoot value of 0 seconds, a delay time value of 16.5 seconds, and a steady state error value of 0 seconds.
