Abstract

Detergent is an ingredient used to maintain cleanliness. In the manufacture of detergents, an active ingredient in the form of LAS (Linear Alkylbenzene Sulfonate) surfactant is often added to kill bacteria. In addition to using synthetic materials, natural ingredients can also be used that can act as antibacterial. One of the natural ingredients with antibacterial activity is hibiscus leaves (Hibiscus tilianceus L). The use of hibiscus leaf extract as a substitute for LAS surfactants aims to reduce the impact of environmental pollution The purpose of this research was to find the right formula in the manufacture of liquid detergent made from hibiscus leaf extract and determine its quality based on SNI 06-0475-1996. The research method used is experimental research that produces qualitative and quantitative data. Qualitative data include phytochemical tests, organoleptic tests, hard water emulsion stability tests, and cleaning power tests. The resulting quantitative data includes the characteristics of the liquid detergent produced based on testing pH, specific gravity, antimicrobial test, phenol coefficient, and levels of active substances. Based on the study, results showed that hibiscus leaf extract contained secondary metabolites in the form of saponins, triterpenoid/steroidal saponins, flavonoids, and polyphenols. The antibacterial test showed that hibiscus leaf liquid detergent had antibacterial activity 1.67 times more effective than phenol. The product test results show that the liquid detergent of hibiscus leaves has the quality according to SNI 06-0475-1996.Keywords: Hibiscus Leaf Extract; Eco-Friendly Detergent; Hibiscus leaves; Surfactant; LAS (Linear Alkylbenzene Sulfonate)

Abstract

Pennywort is a biological plant that is included in the medicinal plant species. The analysis was carried out to obtain information and to find out that endophytic molds from pennywort (Centella asiatica (L.) Urban) can produce extracellular enzymes (amylase, cellulase, pectinase, protease, glucanase, and laccase). Based on the analysis that has been carried out, several conclusions are obtained, endophytic fungi from pennywort with isolate codes MB 20, MM 1, MM 6, MM 8, and MM 16 capable of producing extracellular amylase enzymes, endophytic fungi from pennywort with isolate codes MM 1, MM 12, MM 16, MM 18, MM 19, MM 20 and MM 21 were able to produce extracellular cellulase enzymes, endophytic fungi from pennywort with isolate codes MB 1, MB 3, MB 4, MB 6, MM 1, MM 9, MM 11, MM 13, MM 14, MM16, MM 19, MM 20 and MM 21 were able to produce extracellular glucanase enzymes, endophytic mold isolates from pennywort were proven to be unable to produce extracellular enzymes laccase, pectinase, and protease, and endophytic molds from pennywort with isolate codes MB 1, MB 20, MM 14 and the MM 16 is capable of producing siderophores.Keywords: Centella asiatica (L.)

Abstract

The acid-base titration experiments at Senior High Schools typically use phenolphthalein and methyl orange indicators, which are relatively expensive and harmful to the environment. One of the plants containing anthocyanin pigments is boat lily (Rhoeo spathaceae (Sw.) Stearn) leaves. The research aims to determine the potential analysis of boat lily leaf extract as an alternative indicator used in chemistry learning in titration acid-base learning. The type of research used in this study is descriptive qualitative. Based on the research and discussion results, the pedagogical aspects carried out by chemistry teachers obtained results that using boat lily leaf extract indicators in acid-base titration in the acid-base chapter is appropriate and meets pedagogical terms to be applied by chemistry teachers. A review of chemistry teachers, laboratory employees, and students obtained results that the use of boat lily leaf extract indicators in acid-base titration in the acid-base chapter can be approved because it meets the aspects of ease to be applied in learning, understanding, and attractive to students, and ease of being provided in the laboratory. Based on the feasibility analysis of potential experiments, boat lily leaf extract is feasible based on financial aspects and shelf life resilience.
