This community service was carried out on two topiks, there are a simple chemical practicum and the socialization of the risk of Plastik waste in Soe City, East Nusa Tenggara Province. This activity aims to increase the people's understanding of the chemical science which is considered dangerous for the organism. The mistake in understanding of chemical concept causes the chemistry science is to difficult to study, even though chemistry has comprehensive benefits in life, such as in agriculture for fertilizer production, in pharmacy to synthesis the medicine, for culinary to nutrient content estimated, in the livestock sector to make vaccines, in the marine sector to manage the marine product and for environment to overcome the environmental pollution due to the waste. This activity was initiated by the students and lecturers in the Chemical Education Study Program, of Widya Mandira Catholic University with the target being Junior High School students in the Soe city. Simple practicum is done using natural materials around in order to create an easy chemistry lesson. In addition to practicum activities, there are also has a socialization activities about the risk of Plastik waste, because Plastik waste is an environment problem in the future.

Turmeric is a tropical plant that is widely found on the Asian continent which is extensively used as a food coloring agent and fragrance. Ginger is a spice plant that it often found in South Asia which is widely has spread throughout the world. Coconut is an annual plant, has a hard stem and is generally not branched (monopodial), has fibrous roots, and contain water that is clear and tastes sweet, young coconut water has benefits such as antibacterial, beauty treatment, as an isotonic agent, and carry out the urination. This research was conducted to obtain information about the physicochemical properties and secondary metabolites contents of the coconut water, ginger and turmeric combination extract. The research method was carried out by mixing the mashed turmeric and ginger with the young coconut water and then macerated. The resulting extract was then tested for physicochemical properties (solubility) and identified groups of secondary metabolites (flavonoids, tannins, saponins, and steroids/triterpenoids. The extract was soluble in 70% ethanol. In addition, the combination of young coconut water, ginger, and turmeric extract contain a group of secondary metabolites among others flavonoids, tannins, saponins, and triterpenoids.

Traditionally in the village of Alor, East Nusa Tenggara Province, a combination of avocado and papaya leaves is often used to treat malaria. To be able to be developed as an ingredient in traditional medicine, it is necessary to conduct preliminary research to determine the content of secondary metabolites contained in the combination of avocado and papaya leaves. This study aims to determine the secondary metabolites contained in avocado and papaya leaves through phytochemical screening and Thin Layer Chromatography (TLC) analysis. Extraction was carried out using methanol solvent by maceration, and the extract yield was 91.4%. Testing the content of secondary metabolites in avocado and papaya leaf extracts was carried out by phytochemical screening. Furthermore, the TLC test was carried out to confirm the presence of a positive group of compounds on phytochemical screening, and to determine the chromatographic profile of the extract. After being tested by phytochemical and TLC analysis, the extract contains several metabolites, including flavonoids, alkaloids, tannins, saponins, and steroids. The TLC system used in this study can separate the phytochemical content and give positive results that confirm the results of the phytochemical screening.
