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

Palm oil liquid waste or waste processing CPO (Crude Palm Oil) commonly called CPO (Crude Palm Oil) trenches are very potential to be processed into biodiesel. At the moment, CPO (CPO trenches) processing waste is only considered as waste that pollutes the environment and is not of economic value. If left continuously, palm oil liquid waste that has a pH of 4.2 (acidic) will cause problems for the environment if disposed of directly. One form of utilization of CPO trenches that can be done is by converting it into biodiesel. The manufacture of biodiesel from CPO trenches uses transesterification reactions such as the manufacture of biodiesel in general, with pretreatment to lower the acid figures in the CPO trenches. Biodiesel was obtained later in the analysis of quality standards based on SNI 04-7182-2006 and obtained results that meet the requirements for four parameters, namely the content of FFA samples before the transesterification process is 1.82%. Tan biodiesel content of 0.3055 mg KOH/g. The content of free glycerol is 0.0198% and the total glycerol is 0.0884%.
