Abstract

Accurate control of liquid level and flow is essential in industrial processes to ensure efficiency and product quality. Conventional single PID control methods often suffer from steady-state errors and slow response times due to the dynamic interaction between level and flow. This research develops a cascade control system using a PLC integrated with a Node-RED based Industrial Internet of Things (IIoT) platform to overcome these limitations. The cascade control system applies two control loops, the outer loop for level control and the inner loop for flow control, with PID parameters optimized through trial-and-error method. IIoT integration enables real-time monitoring, remote control, and data logging through an interactive dashboard. Experimental results show the system is able to achieve stability with steady-state error reduced to ± 0.5 cm, faster settling time and rise time, and better disturbance resistance. Very low communication delays support real-time operation. The system offers a practical and effective solution for precise liquid level and flow control, aligned with the demands of Industry 4.0 and can be a model for educational and industrial applications.

Abstract

Oil palm plantations, can be utilised as part of agroforestry systems to mitigate some of the negative impacts of deforestation in East Kalimantan. This research was conducted through a desk-based study and field assessment to explore how these expectations play out in the palm oil sector in East Kalimantan. Research find that oil palm plantation poses serious deforestation challenges to the concept of green growth, as 44% of land allocated for plantations is still forested. At the same time, there may be opportunities to avoid deforestation and pursue more sustainable oil palm development pathways, as 87% of concessions have yet to be planted, however it has yet to be seen whether the political will exists to pursue this shift in policy. However, the conversion of forests to oil palm plantations, including those implemented as agroforestry systems, still poses ecological and social challenges. The development of oil palm plantations is supported by several government regulations, although their implementation in the regions creates various obstacles.
