Abstract

Cancer is a group of deadly diseases that attack human organs with an increasing number of cases and an increasing number of deaths from year to year. Free radicals as unstable molecules are one of the triggers for the emergence of cancer. Katang-katang or I. pes-caprae L. is a plant that could be found on almost all tropical coasts. So it has the potential to be developed as herbal medicine. This study used Flowers of I. pes-caprae L. as the research sample. This study aimed to identify the anticancer and antioxidant potential of the flower extract of I. pes-caprae L extracted with water as a solvent. This research included the phytochemical test of secondary metabolites, identification of anticancer potential based on the toxicity test using the Brine Shrimp Lethality Test (BSLT), and the antioxidant activity test using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) method. The results showed that the flower extract of I. pes-caprae L. from water solvent contained active compounds including alkaloids, flavonoids, tannins, saponins, and terpenoids. The extract also has the potential as an anticancer with an LC50 value of 170.8441 ppm and strong antioxidant activity with an IC50 value of 71.7895 ppm.

Abstract

Briket adalah bahan bakar padat, maka didalam penyalaannya memerlukan waktu sedikit lebih lama dibandingkan dengan bahan bakar cair dan gas. Reaksi pembakaran dari bahan bakar padat berupa arang karbon dengan oksigen pada permukaan partikel akan menghasilkan karbon monoksida dan karbon dioksida. Sebelumnya ditimbang massa biobriket, biobriket yang telah jadi dimasukkan kedalam Reaktor, temperatur diset masing-masing campuran briket pada suhu 300°C sampai 350°C dan regulator dinyalakan, setelah temperature tercapai maka laju alir dialirkan dari tabung oksigen menuju Reaktor sebanyak 1 liter/menit. Kemudian dari hasil pembakaran yang terjadi didalam reaktor terjadi reaksi dimana C + O2 → CO2 + H2O yang kemudian akan diteruskan menuju Kondensor, pada proses kondensasi dihasilkan berupa kondensat yang dianggap H2O yang keluar dan gas yang akan menekan pada tangki penampung yang beisi air sehingga akan keluar air menuju penampungan gelas ukur, air yang keluar dianggap sebagai CO2, dicatat ketinggian volume kondensat dan gas selang waktu 10 menit sampai 60 menit, setelah itu ditimbang massa briket setelah pembakaran, prosedur ini diulangi untuk campuran biobriket lainnya. Berdasarkan hasil penelitian dapat disimpulkan bahwa temperatur optimum dalam proses pembakaran yaitu 300°C dengan nilai konstanta reaksi pada campuran batubara dengan biomassa kulit durian 14647.13/menit, tempurung kelapa 14400.24/menit, serbuk gergaji 15244.90/menit.

Abstract

This research aims to evaluate the effectiveness of activated charcoal produced from coconut shells in reducing ammonia (NH3) levels in domestic wastewater. Liquid waste containing ammonia can cause environmental pollution and negatively impact ecosystems. Therefore, an efficient method is needed to reduce ammonia levels. In this study, activated charcoal was made through the carbonization process of coconut shells and tested for its ability as an adsorbent. The research was conducted experimentally with variations in the mass of activated charcoal of 600 mg, 800 mg, and 1 g. The research results show that coconut shell activated charcoal meets the specifications of Indonesian Industrial Standard (SNI No. 06-3730-1995) with a moisture content of 3%, ash content of 6%, volatile matter content of 14%, and pure activated carbon content of 77%. The reduction in ammonia content obtained was 59.76% for a mass of 600 mg, 61.1% for a mass of 800 mg, and 67.59% for a mass of 1 g. These results indicate that activated coconut shell charcoal has good potential as an adsorbent for the treatment of liquid waste containing ammonia. This research is expected to contribute to the development of more environmentally friendly waste treatment technologies and the sustainable use of local resources.

Abstract

Bio-batteries are one alternative as well as a solution to the limited use of electrical energy. Batteries that are widely used today are sourced from chemicals in the form of heavy metals such as mercury, lead, cadmium, and nickel, which can pollute the environment if not disposed of properly. Efforts to reduce the use of chemicals that pollute the environment need innovation to overcome the problem. This study aims to determine the formula for bio-batteries that have a long life. The method used is to mix banana peel and breadfruit peel that has been fermented with variations of b/vv (g/mmL) with a composition of 0, 25, 50, 75, and 100% at each concentration. The parameters observed in this study were pH and voltage measurements during the fermentation process for 7 days, and the bio-batteries that had been made were tested for potential differences in electric current, power, resistance, and durability. As a result, the optimum condition of the bio-battery was obtained in a mixture of 75% banana peel compared to 25% breadfruit peel by producing a potential difference of 1.37 V, an electric current of 1.5 mA, and a power of 0.68 mW. A bio-battery with a composition of 75% banana peel compared to 25% breadfruit peel can last a maximum of 31 hours and 28 minutes when used on a wall clock.
