Abstract

Pada penilitian terdahulu laboratorium Instrumentasi dan control memiliki sistem pneumatic air supply, namun terdapat beberapa kekurangan, penelitian sebelumnya hanya berfokus pada strategi pengendalian tekanan, efisiensi kompresor, maupun pengaturan aliran udara. Namun, penelitian tersebut belum mengintegrasikan sistem penyimpanan udara bersih (clean tank) yang dilengkapi pengendalian tekanan otomatis, pemantauan tekanan secara real-time, Penelitian ini bertujuan merancang dan membangun sistem pneumatic air supply untuk menyediakan udara bertekanan yang stabil, bersih, dan mendukung kegiatan praktikum serta penelitian di laboratorium. Sistem yang dikembangkan memanfaatkan kompresor yang telah tersedia dan dilengkapi dengan air receiver tank, air filter, pressure switch, pressure transmitter, serta sistem monitoring berbasis ESP32 dan LCD Nextion sebagai monitor. Pengendalian tekanan menggunakan metode ON–OFF berdasarkan set point yang ditentukan dari pressure switch, sedangkan parameter tekanan dimonitor secara real-time melalui LCD Nextion Hasil pengujian menunjukkan pressure switch mampu mengendalikan kompresor secara otomatis sesuai set point. Penggunaan dua filter menurunkan kelembapan udara dari 73,9% menjadi 52,9%, sedangkan validasi pressure transmitter terhadap pressure gauge menghasilkan rata-rata error 0,921% dengan akurasi 98.48%. Waktu pengisian clean tank hingga tekanan 6 bar adalah 580 detik, sehingga sistem dinilai mampu menyediakan udara bertekanan yang stabil dan layak digunakan untuk operasional Laboratorium Instrument & Control.

Previous research has developed a pneumatic air supply system for the Instrumentation and Control Laboratory; however, several limitations remain. The previous study mainly focused on pressure control strategies, compressor efficiency, and airflow regulation. However, it did not integrate a clean air storage system (clean tank) equipped with automatic pressure control and real-time pressure monitoring. Therefore, this study aims to design and develop a pneumatic air supply system capable of providing a stable and clean compressed air supply to support laboratory practical activities and research. The developed system utilizes an existing air compressor integrated with an air receiver tank, air filter, pressure switch, pressure transmitter, and a monitoring system based on an ESP32 microcontroller and a Nextion LCD display. Pressure control is implemented using the ON–OFF control method based on the pressure switch set points, while the pressure is monitored in real time through the Nextion LCD. The experimental results demonstrate that the pressure switch is capable of automatically controlling the compressor according to the predefined set points. The implementation of a two-stage filtration system reduced the air humidity from 73.9% to 52.9%, while the validation of the pressure transmitter against a pressure gauge resulted in an average error of 0.921% with an accuracy of 98.48%. Furthermore, the clean tank required 580 seconds to reach a pressure of 6 bar, indicating that the proposed system is capable of providing a stable compressed air supply and is suitable for supporting the operational activities of the Instrumentation and Control Laboratory.
