Abstract

Solanum ferox is a typical Central Kalimantan plant widely used by Dayak’s community as a vegetable. The study aims to determine the ethanol extract of sour eggplant activities by measuring its SPF in vitro and identifying secondary metabolite contents. The sour eggplant is extracted by maceration using 96% ethanol solvent and then bound with an evaporator. The secondary metabolite groups of ethanol extract were identified using phytochemical screening. The identification results indicate the presence of flavonoid, terpenoid, steroid, and phenolic compounds. Then, the ethanol extract was fractionated with a water solvent, and its functional cluster was identified using the IR spectrum. IR spectral identification results indicate the presence of OH, C-O, C=C olefin, C -O ether, and aliphatic CH functional groups. (CH2 and CH3) SPF values were determined by measuring the absorption of ethanol and water extracts in vitro using UV-Vis spectrophotometry at UV-B wavelengths of 290-320 nm. In vitro testing has been conducted as a preliminary test in developing a sunscreen product (active substance). The SPF values of ethanol extract and water from weighted fruit extract in sequence are 40 and 23 at a 10% concentration with ultra-category.

Abstract

Entrepreneurship is an indicator in seeing the progress of a nation and state. To become a developed country requires a minimum of 20% of entrepreneurs from the total workforce, while Indonesia is still below 8%. Therefore, the core of this community service program is to inspire the spirit of entrepreneurship from an early age to students. Hopefully, in the future, these students will become skilled and competent entrepreneurs. Technically, this entrepreneurship service is to provide a theoretical and practical understanding of entrepreneurship to teenagers, especially students of State Senior High School 4 Palangka Raya. This training is expected to be a provision for them after graduating from school, if they want to start their own business. The method involves training with various materials and visual materials related to entrepreneurship. At the beginning of the activity, students were given an understanding of entrepreneurship in theory, namely the history of entrepreneurship, business theory, financial statements, and business feasibility studies. After that, participants were given an understanding of entrepreneurship through speakers who came from practitioners / entrepreneurs. The material from the practitioner is the experience and tips of entrepreneurship. Then this activity was continued with questions and answers between participants and speakers. Evaluation was conducted through a pre-test (before material exposure) and post-test (after material exposure and Q&A) to measure students' understanding and interest in entrepreneurship. Before receiving the training, participants may feel afraid or hesitant regarding the risks that may arise during entrepreneurship. However, after receiving the training, students began to feel more confident and realized the positive impact they could experience if they were involved in entrepreneurship. This can also be seen from the increase in understanding by 36% of all participants.
