Abstract

The purpose of this study was to demonstrate an alternative solution as an insecticide from Indonesian natural ingredients. We investigated the potential use of Artocarpus altilis park (known as kluwih plants in Indonesia) for an anti-mosquito repellent because it contains flavonoids and saponins. The use of this type of insecticide is harmless, inexpensive, and largely available in Indonesia. In the experiment, we extracted bark and leaves of kluwih to obtain insecticidal material to repel Anopheles sp. To ensure the precise extraction and insecticidial effect, the experiments were conducted four times with three repetitions. For each experiment, we used 8.4 mL with the concentrations of 20, 30, and 40% of flavonoid. The results showed that the higher the concentrations of bark and leaf extracts of Artocarpus altilis park the higher the mortality rate of Anopheles sp is.

Abstract

Today, the continuous use of paper makes various countries experience a tree crisis due to continuous logging. Therefore, the obstacle faced in making paper is the lack of availability of wood raw materials used in the manufacturing process. Currently, various countries are starting to think about other alternatives in paper making. In this study, the use of cassava peels in papermaking can be a solution in meeting the needs of raw materials for papermaking because the content contained in cassava peels can be used as material for making pulp. The experiment of making cassava pulp was carried out using the organosolv process, which is cooking to separate the fibers using organic chemicals. The chemical used in the cooking process is ethanol. The research method used was Completely Randomized Design (CRD). The experiment was carried out with 3 treatments and 3 repetitions. with each concentration of ethanol in the cooking treatment that is 50%, 70% and 90%. Data analysis was carried out by measuring the thickness, gram, age, and tensile strength of the paper. From the experiments conducted, it is proven that using cassava peel can be used as an additional material in making paper. The most effective concentration of ethanol is at a concentration of 90%.
