Abstract

Hygiene in food affects human health. Unhygienic food can cause people to contract dangerous diseases. One way to maintain hygienic values ​​is by washing eating utensils. Washing cutlery usually uses a sponge. Continuous and irregular use of foam sponges can cause bacteria to enter the human body. Alternative Solution is making environmentally friendly sponges from coconut fiber with a combination of fragrant pandan leaf extract as an anti-bacterial. The research method is descriptive with a quantitative approach. Data collection through observation and literature study. Product effectiveness indicators: 1) Meets antibacterial tests; 2) Water absorption test; 3) Organoleptic test; 4) resistance test and 5) pH test. The data analysis technique used is quantitative descriptive. From the test results, the coconut fiber sponge met the antibacterial test better than the foam sponge, leaving 75 colonies with a pandan leaf extract concentration of 75%. The coconut fiber sponge meets SNI, the sponge's water absorption capacity is 10.62%. Organoleptic tests show that coconut fiber sponge meets SNI for sponges including aroma and texture. Durability tests show that the coconut fiber sponge can last more than 3 weeks. The pH test shows that the coconut fiber sponge has a neutral pH of 6.2 so it is safe in direct contact with the skin. Abstrak Kehigienisan pada makanan berpengaruh terhadap kesehatan manusia. Tidak higienisnya makanan dapat menyebabkan manusia terjangkit penyakit berbahaya. Salah satu cara dalam menjaga nilai higienis yaitu dengan mencuci peralatan makan.  Pencucian alat makan biasanya menggunakan spons. Penggunaan spons busa secara terus menerus dan kurang teratur dapat mengakibatkan bakteri masuk ke tubuh manusia. Solusi alternatif solusi adalah dengan pembuatan spons ramah lingkungan dari serabut kelapa dengan kombinasi ekstrak daun pandan wangi sebagai anti bakteri. Jenis penelitian adalah deskriptif dengan pendekatan kuantitatif. Pengumpulan data melalui observasi dan studi pustaka. Indikator efektivitas produk: 1) Memenuhi uji antibakteri; 2) Uji daya serap air; 3) Uji organoleptik; dan 4) uji ketahanan dan 5) uji pH. Teknik analisis data yang digunakan adalah deskriptif kuantitatif. Dari hasil pengujian spons serabut kelapa memenuhi uji antibakteri yang lebih baik dibandingkan spons busa menyisakan 75 koloni dengan konsentrasi ekstrak daun pandan 75%. Spons serabut kelapa memenuhi SNI daya serap air spons sebesar 10,62%. Uji Organoleptik menunjukkan spons serabut kelapa memenuhi SNI spons meliputi aroma dan tekstur. Uji ketahanan menunjukkkan spons serabut kelapa mampu bertahan lebih dari 3 minggu. Uji pH menunjukkan spons serabut kelapa memiliki pH netral yaitu sebesar 6,2 sehingga aman bersentuhan langsung dengan kulit.

Abstract

The toilet floor is a surface that is frequently contacted by human feet, making it an ideal environment for the proliferation of germs and bacteria. One frequently utilized antibacterial compound is chitosan, which is derived from shrimp shells. However, the unmanaged disposal of shrimp shell waste has the potential to cause environmental issues. The objective of this study is to utilize Averrhoa bilimbi extract as a base material for a toilet cleaning liquid, with the addition of chitosan derived from shrimp shell waste. This research concept employs chitosan derived from shrimp shells, which exhibits antimicrobial properties and has the potential to serve as a cleaning agent, in conjunction with Averrhoa bilimbi extract, which is rich in citric acid and functions as a natural cleaning agent. The research design is descriptive and employs a qualitative comparative approach. The ratios of Averrhoa bilimbi extract and baking soda to chitosan were varied, including 25:1:1, 25:1:2, and 25:1 (with no chitosan as a control). The findings indicated that all cleaning liquid samples satisfied the pH standard outlined in SNI 1842:2019. The sample with the ratio of baking soda, Averrhoa bilimbi, and chitosan at 1:25:2 exhibited the optimal level of cleanliness and the most concentrated aroma. This study demonstrates that Averrhoa bilimbi extract can serve as an environmentally sustainable toilet cleaning agent when combined with shrimp shell waste.

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.
