Abstract

This research is an experimental study where the variables in this study are divided into three categories, independent, dependent, and confounding variables. From this research, qualitative data and quantitative data were obtained. The qualitative data includes the results of the phytochemical screening test. The quantitative data includes pH test, bioinsecticide effectiveness test, and preservative effectiveness test. Based on the results of the phytochemical analysis, it shows that ketapang and brotowali leaf extracts contain secondary metabolites in the form of saponins, flavonoids, alkaloids, and tannins. The bioinsecticide with the best formulation is the bioinsecticide with a formula of 15% extract because it has an LC50 value that is close to the LC50 value of the probit regression, which is 13.05%. Based on the results, it shows that the bioinsecticide of ketapang leaves and brotowali stems for all formulas has met the quality qualifications according to the requirements in SNI 06-0475-1996.

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%.
