Abstract

PT. Indolakto-Pandaan merupakan salah satu industri yang bergerak dalam bidang pengolahan susu (dairy manufacturing). Setiap tahun PT. Indolakto-Pandaan memiliki program kerja untuk menurunkan penggunaan energi sebesar 3% dari tahun sebelumnya dengan melakukan pengembangan dan inovasi, salah satunya pada kegiatan proses Aerasi di instalasi pengolahan air limbah. Pada instalasi pengolahan air limbah pengguna energi tertinggi adalah Blower, dengan pemakaian 223 kWh per hari. Metode operasional kendali Blower masih dilakukan secara manual, dimana petugas mengatur kecepatan Blower dengan mengubah frekuensi Variable Speed Drive (VSD) sesuai dengan kondisi konsentrasi oksigen dalam air limbah. Sistem yang dijalankan secara kontinyu oleh manusia mengakibatkan sering terjadinya kelalaian sehingga penggunaan energi Blower meningkat. Proyek Akhir ini bertujuan untuk membantu program kerja menurunkan penggunaan energi yang digunakan Blower dengan merancang sistem kontrol konsentrasi oksigen terlarut menggunakan logika fuzzy. Rancangan sistem terdiri dari sensor Dissolved Oxygen, LCD, serta mikrokontroler Arduino yang terdapat logika fuzzy. Sensor Dissolved Oxygen akan digunakan untuk mengukur konsentrasi oksigen terlarut kemudian data pengukuran dikirimkan ke Arduino. Data tersebut kemudian diolah oleh logika fuzzy untuk menentukan output kecepatan Blower berdasarkan rule pada proses inferensi di logika fuzzy. Berdasarkan data dari pengujian dan analisa sistem kontrol konsentrasi oksigen terlarut dapat diketahui bahwa terdapat hubungan pertambahan kecepatan Blower dengan pertambahan konsentrasi oksigen terlarut, juga didapatkan hasil bahwa sistem dapat menurunkan penggunaan energi harian Blower.

PT. Indolakto-Pandaan is one of the industries engaged in dairy manufacturing. Every year PT. Indolakto-Pandaan has a work program to reduce energy use by 3% from the previous year by developing and innovating, one of which is the Aeration process at the wastewater treatment plant. At the wastewater treatment plant, the highest energy user is blower, with consumption of 223 kWh per day. The operational method of controlling the blower is still done manually, where the officer regulates the speed of the blower by changing the frequency of the Variable Speed Drive (VSD) according to the condition of the oxygen concentration in the wastewater. Systems that are run continuously by humans result in frequent negligence so that the use of blower energy increases. This final project aims to help work programs reduce energy use used by blowers by designing a dissolved oxygen concentration control system using fuzzy logic. The system design consists of a Dissolved Oxygen sensor, an LCD, and an Arduino microcontroller which contains fuzzy logic. The Dissolved Oxygen sensor will be used to measure the dissolved oxygen concentration then the measurement data is sent to the Arduino. The data is then processed by fuzzy logic to determine the output speed of the blower based on the rules in the fuzzy logic inference process. Based on data from testing and analysis of the dissolved oxygen concentration control system, it can be seen that there is a relationship between the increase in blower speed and the increase in dissolved oxygen concentration.
