ABSTRAK

Pada sistem pengendalian temperatur ini merupakan suatu rancangan sistem yang mampu mengendalikan temperatur pada miniplant biodiesel process khususnya pada tangki pencampuran minyak dan larutan metoxida yang terdiri dari methanol CH3OH dan katalis KOH. Plan pengendalian temperatur ini menggunakan sistem pengendalian bermode onoff dan menggunakan LM35 sebagai sensor suhu microcontroller sebagai controller LCD yang berfungsi untuk menampilkan data dan dua aktuator yaitu heater dan solenoid valve. Cara kerja dari plan pengendalian ini yaitu sensor LM35 akan mendeteksi perubahan suhu pada tangki pencampuran kemudian diolah oleh microcontroller sehingga perubahan suhu dapat ditampilkan melalui LCD. Pada tangki ini suhu ideal pencampuran minyak dan metoxida adalah 55-65C maka data yang diambil juga berbeda dengan set point yaitu 55 C 60C 65C. Pada hasil pengujian dapat terlihat bahwa semakin cepat waktu untuk mencapai set point semakin cepat bereaksi pada proses pencampuran minyak dan metoxida. Untuk perhitungan akurasi sistem didapatkan bahwa sistem pengendalian temperatur tangki pencampuran mempunyai akurasi sebesar 98 .


ABSTRACT

The temperature control system is a system than can control the temperature of biodiesel miniplant process especially in the mixing tank of oil and metoxide that consist of methanol CH3OH and catalyst KOH. The temperature control system are used on-off control mode with LM35 as temperature sensormicrocontroller as controllerLCD as displayed of dataand used two kinds of actuator solenoid valve and heater. The work principle of the control plant is beginning from temperature sensor. The temperature is change of mixing tank would detected by LM35 temperature sensor. Thenthe information that getting by this sensor will be processed by micocontroller. The last the display of temperature is change is appearance in LCD. At tis tankthe ideal temperature for mixed the oil and metoxide is about 55 C- 65 C then data are taken is also different from set point is 55 C 60 C 65 C. The result of system axamination can be seen that the time faster to get the set point means that the reaction is faster on the mixing oil and metoxide process. Then the calculation result of accuration system is 98 percent.
