Abstract

The increasing population in Indonesia is proportional to the increase in the use of detergents. Detergent is an active pollutant that causes an increase in water pollution. One of the efforts to reduce the levels of detergent pollutants is to use soybeans fermented by the bacterium Bacillus subtilis. Fermented soybeans contain polyglutamic acid which is a natural water purifier. The utilization of soybeans in this study is because soybeans are easy to find in Indonesia, safe terms of health, and have an economical price. The research conducted at SMA Trensains Muhammadiyah Sragen aims to reduce the levels of detergent pollutants in water by filtrated them. This study uses the grounded theory method, namely research that starts from an existing theory. Then field observations were made to test the truth of the previous theory. The results showed that soybean fermentation was proven to be able to reduce the levels of detergent pollutants in the water so that the water can be uses.

Abstract

Indonesia is the second agrarian country in the world, produces a very large agricultural waste. However, this has not been used optimally. Examples are egg shell waste, coconut fiber and bagasse. Bagasse waste has a high fiber content. Meanwhile, coconut coir contains cellulose and lignin which makes coconut coir less brittle. The purpose of this study was to determine the effectiveness of Nacobrick as an environmentally safe brick innovation. This type of research is a qualitative descriptive study where the focus of the description is on making brick innovations. The method of collection is through observation. The tests carried out are the water absorption test, the visible properties test, the compressive strength test, and the specific gravity test. The data obtained in this study were analyzed using descriptive methods. Based on the tests carried out, the results obtained details of the size of 30cm x10cmx15cm, with no defects on the outside. The compressive strength value is 25,074 kg/cm2 and the water absorption value is 14.8%. This study succeeded in identifying the effectiveness of Nacobrick on the effectiveness of environmentally friendly bricks as an environmentally safe brick innovation.

Abstract

Energy is important part in human life. However, energy sources in Indonesia are still dominated by non-renewable energy sources. The depletion of non-renewable energy sources, there is a shift to use renewable energy sources, one of which is solar cells. Dye Sensitized Solar Cell (DSSC) is a device that can convert light energy into electrical energy. DSSC is a third-generation solar cell consisting of TiO2 semiconductors placed on a conductive glass substrate and immersed with dyestuffs. The dye as a sensitizer used comes from the skin of the red dragon fruit (Hylocereus costaricensis). DSSC is formed with a sandwich structure, there are five parts, namely ITO glass (Indium Tin Oxide) as a substrate, TiO2 as a semiconductor material, dye (red dragon fruit skin) as an electron donor, gel electrolyte as electron transfer and active carbon as a catalyst in the comparison. This study aims to prove that organic compounds can be used as photosensitizers to produce solar-powered electric current. Researchers use descriptive methods with a quantitative approach. The test methods carried out are voltage tests, electric current tests, fill factors, power, and efficiency. Based on the tests carried out, the results of the voltage test of 199.3 mV, the electric current test of 199.3 mV, the Fill Factor of 1.379%, and the efficiency of 1.948 x10-5%. This research successfully proved that DSSC with Dragon Fruit Skin as a photosensitizer can produce electrical current and voltage.
