This research aims to design and develop a prototype Continuous Emission Monitoring System (CEMS) with a minimum Local Content (TKDN) target of 40% to replace imported CEMS products currently used in various domestic industries. The main innovation of this research lies in the substitution of imported product components and the modification of the probe system for in-situ CEMS applications. This modification includes the placement of various sensors inside the probe pipe to ensure that the temperature and pressure of emissions in the stack match the temperature and pressure of emissions when measuring the quality of SO₂, NO₂, O₂, CO₂, and CO by the sensors within the probe, without requiring an emission preheater as mandated in the extractive method. The results of this modification demonstrate high accuracy, continuous, real-time, and online measurements. This prototype is designed to meet emission measurement standards set by the Ministry of Environment and Forestry (KLHK) as well as international standards. Field trials show that this prototype not only successfully achieves the desired TKDN but also meets the emission measurement standards set by KLHK and international standards, and is capable of delivering performance equivalent to imported products. The results of this research make a significant contribution to the development of local technology and the reduction of dependence on imported products in the emission measurement sector to support the achievement of sustainable development goals in the environmental field.
