Abstract

Peternak kambing HKP Farm Benowo Surabaya menghasilkan susu kambing sebanyak 100 liter per-minggu, untuk meningkatkan nilai jual dapat dilakukan pengolahan susu menjadi kefir, kefir memiliki manfaat bagi kesehatan tubuh manusia dan memiliki daya simpan yang lebih lama dibandingkan dengan susu biasa. pembuatan kefir diperlukan proses pasteurisasi bertujuan menghilangkan mikroorganisme pathogen. Penggunaan bejana double jacket agar hasil susu yang dihasilkan lebih baik, pada proses pasteurisasi standard yang digunakan yaitu 1995 dengan setpoint HTST Selama 15 detik dan LTLT Selama 30menit dikontrol dengan pemanas heater, sensor RTD PT 100 dan mikrokontroler Arduino Mega2560 serta akan termonitoring di LCD Nextion. Pada pengujian setpoint HTST Selama 15 detik untuk mencapai setpoint dibuthkan waktu selama 51 menit 23 detik, mencapai maximum overshoot di angka 51 menit 28 detik, mencapai settling time pada temperatur
untuk mencapai setpoint pertama kali dibutuhkan waktu selama 46 menit, mencapai maximum overshoot di angka 51 menit, mencapai settling time pada temperatur 71.9oC s/d 72.19oC selama 15 detik dan disetpoint LTLT dapat terjaga di temperatur 62,8oC s/d 64,8oC selama 30 menit. ===================================================================================================================================
HKP Farm Benowo Surabaya, produces 100 liters of goat milk per week. To increase the value of their product, have to process the milk into kefir. Kefir offers various health benefits and has a longer shelf life compared to regular milk. The production of kefir requires a pasteurization process to eliminate pathogens.To ensure high-quality result, a double jacket vessel is used during pasteurization process. The standard pasteurization procedure follows SNI 01-3951-1995, with an HTST setpoint of 72oC for 15 seconds and an LTLT setpoint of 63 oC for 30 minutes. The process is controlled using a heater, RTD sensor PT 100 sensor, and Arduino Mega 2560 as a microcontroller, with monitoring display on an LCD Nextion. During testing phase, for the HTST setpoint 72oC for 15 seconds it took 51 minutes and 23 second to reach the setpoint, the maximum overshoot recorded was 72.68oC, which occurred after 51 minutes and 28 seconds the settling time ranged from 72.05 oC to 72.19 oC and took 51 minutes and 33 seconds to stabilize, with a steady-state error 25%. In the testing phase of the LTLT setpoint 63 oC for 30 minutes it took 46 minutes to initially reach the setpoint. The maximum overshoot reached 64.87 oC after 51 minutes, and the settling time occurred between 63.07oC and 62.98 oC, lasting for 66 minutes. The steady state-error recorded was 27.7%. although the testing revealed a relatively high steady state error, but the applied on/off system effectively maintained the pasteurization process according to the setpoints. This can be observed from the temperature measurement range, where the HTST setpoint was maintained between 71,9oC until 72.19oC for 15 seconds, while the LTLT setpoint was maintained between 62.8 oC and 64.8 oC for 30 minutes
