Design and Development of Real-Time Plant Process Control Monitoring System in Organic Fertilizer Production

Abstract

In this applied research, a plant controller with capacity of 300 litres has been developed. The system provides graphical user interface (graphics and tables) using Visual Basic program to show and monitor the fermentation process. Communication between the software and hardware is established through microcontroller’s interface. The microcontroller acts as the main controller which controls the humidity, temperature, pH, aerator, heater, exhaust fan, and the speed of the motor. Temperature and humidity sensor (DHT-22), Methane Gas sensor (CH), Carbon Gas sensor (MQ7), and Nitrogen Gas sensor (MiCS-2714) are used in this system. The domestic waste raw materials such as vegetables and sugar cane waste are thinly sliced while the fruits are grinded. Temperature, humidity, and pH readings are collected as reference parameters prior to the process starts. During the anaerobic digestion process, temperature is kept at 40°C ±1 while plant’s tube is maintained at 40°C. When the temperature falls to 39°C, the heater is switched on, when the temperature reach 40°C the heater is switched off. This research is carried on using two kind of mixture models which are: mixture model X (mixture of vegetables, fruits and sugar cane waste) and mixture model Y (same as X with additional rice husk). The mixture model X and Y C/N’s ratio is in compliance with SNI-7030-2004 standard. The real-time plant controller system proposed in this research is successfully.

Design and implementation of smart waste recycling bin for the household environment based on IoT

“…In detail, this smart recycling bin still needs user intervention to ensure that after seven days, liquid fertilizer is already formed and ready to use. Hence, adding and integrating the bin with other sensors that monitor and detect humidity, temperature and pH will make the system automatic (Mardiyanto, 2019). Furthermore, this study did not include power consumption as part of the research discussion because the focus is more on the technical and functional aspects.…”

Pembuatan Mesin Fermentator Pupuk Organik Cair untuk Menunjang Efektifitas Produksi Kelompok Tani di Desa Gucialit, Kabupaten Lumajang, Jawa Timur

“…Fermentasi merupakan proses perubahan bahan organik bio-kimia dengan bantuan organisme mesofilik dan termofilik [9] , fermentasi merupakan proses pembentukan bahan-bahan organik menjadi pupuk dengan dibantunya mikroorganisme sebagai pengurai bahan-bahan organik tersebut. Proses fermentasi dibagi menjadi 2 cara, yaitu tanpa menggunakan udara bebas (anaerob) dan dengan menggunakan udara bebas (aerob).…”

Air quality monitoring and gas leakage detection with automatic shut‐off using wireless sensor‐actuator networks

“…In this regard, Mardiyanto proposes a system for real time monitoring of toxic gases which are consumed and produced during the manufacturing of organic fertilizers. 11 The system monitors parameters such as temperature, aeration and humidity, but most importantly checks the levels of poisonous gases such as Methane, Carbon Monoxide and Nitrogen Dioxide. The system is designed to maintain a certain threshold for gases and to perform actions accordingly, such as turning on the exhaust fan, should they exceed this limit.…”
