Abstract

This study aims to develop starch-based bioplastics using sago starch with the addition of Microfibrillated Cellulose (MFC) and Refuse-Derived Fuel (RDF) fillers to enhance mechanical properties and material sustainability. Sago starch was selected as the base material due to its biodegradability, while MFC derived from empty palm oil fruit bunches served as a structural reinforcement, and RDF was introduced as an additional filler sourced from processed organic and inorganic waste. The bioplastic production process involved starch gelatinization, mixing with MFC and RDF solutions, addition of sorbitol as a plasticizer, casting, and natural drying. Characterization included morphological analysis and mechanical testing. Results showed that the sago starch+MFC bioplastic exhibited a more homogeneous surface morphology and superior mechanical properties, with a maximum tensile strength of 10.6 MPa and elongation at break of 5.7%. The addition of RDF increased material density but reduced homogeneity and toughness, with fracture energy per volume drastically decreasing from 488.28 kJ/m³ to 41.15 kJ/m³. Overall, the combination of sago starch and MFC offered better mechanical performance, while RDF addition requires optimization to maintain structural integrity. This innovation supports waste utilization and promotes circular economy principles in the development of environmentally friendly materials.

Abstract

Furnaces in the production of VCM (Vinyl Chloride Monomer) must be operated with optimal efficiency to maximize production and minimize the formation of impurities (coke). Furnace efficiency is evaluated based on the ratio of heat generated from fuel combustion to heat absorbed by the EDC (Ethyl Dichloride) fluid, and is a key indicator of operational feasibility. In addition, the pressure difference of the inlet convection and outlet radiant sections is used as an additional parameter, where an increase in this value reflects the accumulation of deposits in the tubes. If the efficiency drops below the minimum operating conditions or the pressure difference between the convection inlet and outlet radiant section exceeds 4 kg/cm2G, the furnace is considered unfit for operation and decoking must be performed, which will increase operating costs. During the 12 days of monitoring (measurement every 8 hours), the average efficiency was 85.370%, the highest value was 87.348%, and the lowest value was 83.764%. The efficiency values tended to fluctuate and were below the minimum operating condition (88.898%). This is due to changes in operating conditions and manual control. Therefore, although the pressure difference is still below the threshold of 4 kg/cm2G, the furnace is considered unfit for operation.

Abstract

Water pollution due to human activities causes high levels of household wastewater called greywater. To reduce the impact of water pollution from greywater, wastewater needs to be processed to be safer for the environment. By utilizing technology and independent energy sources from Photovoltaics, a system was created that can purify wastewater and can be controlled and monitored using the Internet of Things. The research entitled "Monitoring and Control System for Photovoltaic Powered Greywater Purifiers Based on the Internet of Things (IoT)" aims to monitor and control water to obtain processed wastewater that produces cleaner water quality. This system can monitor battery charging for pump sources on filters in real time using IoT integrated with an Android application. The way this tool works is by utilizing the ESP8266 nodeMCU as a communication intermediary, Arduino as the tool control center, relays for control, voltage sensors to detect battery and pump voltage, ACS712 sensors to detect charging and pump currents, turbidity and pH sensors to detect water conditions. The results of this research are that the system can monitor water conditions, voltage, and pump current when filtering while controlling the pump based on water conditions, as well as monitoring the charging voltage and current from the PV to the battery.
