Abstract

The availability of electricity significantly impacts the quality of life in society. The absence of electricity in several remote areas can limit access to essential facilities and affect the well-being of residents. One effort to expand electricity access is through the utilization of alternative energy sources. However, using conventional technology to generate electricity in remote areas is often challenging due to geographical conditions and infrastructure limitations.  This study aims to develop a Dye-Sensitized Solar Cell (DSSC) based on miana extract and chlorophyll from alfalfa leaves as an alternative for renewable energy production in remote areas. The research adopts a descriptive method with a quantitative approach. Data collection is conducted through observation and literature review. The indicators of product effectiveness include: 1) open-circuit voltage test; 2) short-circuit current test; 3) optimum voltage test; 4) optimum current test; 5) maximum power test; 6) fill factor test; 7) energy conversion efficiency test. The data analysis technique used is descriptive quantitative. This study concludes that the development of DSSC from natural materials not only supports the provision of alternative energy for remote areas but also reduces dependency on fossil fuels, which are limited and have negative environmental impacts. Natural material-based DSSC provides a sustainable solution for affordable and eco-friendly electricity in areas with limited electricity access.

Abstract

Oily waste is one of the most difficult types of waste to manage due to the lack of filtration facilities for petrochemical industry waste. According to the Ministry of Environment and Forestry, the average amount of oil is 1000-2000 mg/L in industrial liquid waste, which has a negative impact on the aquatic environment and other biota. On the other hand, in 2020, tobacco consumption reached 322 billion sticks, producing approximately 107.3 tons of cigarette butt waste. Cigarette butts contain cellulose acetate, making them solid waste that is difficult to decompose naturally. However, cigarette butt filters, which are rich in cellulose acetate, have great potential as an alternative raw material for membrane technology. This study aims to develop polymer membranes based on recycled cigarette butt waste as an environmentally friendly membrane system for sustainable living, by evaluating the effectiveness of water filtration using these membranes with a minimum permeation flux indicator of 400 L/m²·hour and reducing membrane production costs by ≤ 30% compared to conventional membranes. The method used is descriptive with a quantitative approach, focusing on the utilization of cigarette butt waste as a polymer membrane. Data collection was carried out through experiments, observations, and literature studies. From the tests conducted, the permeation flux test was 474,6-588,5 L/m²/hour, referring to Widiasa’s (2014) research. The water toxicity test with a pH of 7 met SNI 06-6989.11-2004, and the durability test showed that the membrane could be used three times.
