Abstract

This research examines the utilization of Palm Empty Fruit Bunch (PEFB), a byproduct of the palm oil sector, as a sustainable feedstock for bioplastic manufacturing. Bioplastics, derived from natural substances like cellulose, starch, and vegetable oils, offer a sustainable substitute for traditional petroleum-based plastics, which substantially contribute to environmental degradation. This research examines the processes of cellulose extraction, delignification, and the diverse pre-treatment techniques employed to transform PEFB into bioplastics. The findings indicate that PEFB is abundant in cellulose, rendering it a viable material for bioplastic manufacturing. Moreover, the inclusion of plasticizers such glycerol and chitosan enhance mechanical qualities, including tensile strength and flexibility, while preserving biodegradability. The study also emphasizes the influence of various processing conditions and additives on the ultimate attributes of the bioplastic, such as water resistance and mechanical performance. The results indicate that bioplastics sourced from PEFB may aid in diminishing plastic waste and fostering sustainable materials in sectors like packaging. The analysis continues by underscoring the necessity for more research to enhance production techniques and evaluate the scalability of PEFB-based bioplastics in practical applications.

Abstract

Solar energy can be converted into electricity using photovoltaic systems as a strategic measure to achieve the renewable energy mix targets outlined in the National Energy Policy. Photovoltaic Rooftop (PV Rooftop) systems integrated with Building Integrated Photovoltaics (BIPV) present a viable alternative. PV Rooftop technology is currently trending, as evidenced by its increasing adoption in both industrial and residential sectors, supported by the global decline in solar panel prices. However, from an architectural perspective, silicon-based PV panels can reduce the aesthetic appeal of buildings. An emerging solution promoted by architects worldwide is the implementation of semi-transparent, dye-sensitized solar cells (DSSC), which are sensitive to colorants. In addition to their functional properties, DSSCs offer high aesthetic value due to the pigments used. Urban areas hold significant potential for the development of off-grid DSSC photovoltaic systems installed on rooftops and building facades. This study focuses on the analysis of off-grid DSSC PV systems for a type 42 residential house in Palembang City. The research employs a quantitative approach, using literature review and field measurements, followed by technical calculations. The article details the components required for designing an off-grid DSSC photovoltaic system capable of supplying all household electrical loads.
