Abstract

Termiticide activity of methanol extract of Centella asiatica L. Urban against Coptotermes curvignathus Holmgren was investigated using the no choice test. The chemical components of methanol extract of C. asiatica were identified by GC-MS. The antitermite activity showed that the percentage of termite mortality increased when the concentrations of extract increased. The concentrations of 25% indicated the highest termite mortality which reached 100% on the sixth day. Profiling GC-MS methanol extract of C. asiatica revealed 85 chemical components. Based on MS spectral data, 56 chemical components were identified which were grouped into fatty acids (27.09%), esters (23.73%), hydrocarbons (16.56%), ethers (8.28%), sesquiterpenes (1.61 %), alcohol (1.55 %), aldehydes (3.50%), monoterpenes (1.08%), diterpenes (0.67%), steroids (0.43%), and ketones (0.31 %). Among these, the presence of palmitic acid, patchouli alcohol, and β-caryophyllene may be responsible for its termiticide activity. Other compounds such as triterpenoids, saponins, flavonoids, tannins, steroids, and glycosides that were reported previously not detected by GC-MS in this study, possibly contributing to its activity.

Abstract

The aim of this study was to determine the antibacterial activity and the ccombined effect of methanol extract of the ketepeng cina leaves (Cassia alata L.) with six selected plant extracts against Staphylococcus epidermidis using the diffusion and the paper strip methods at a concentration of 10% w/v. The results showed the average antibacterial activity of each extract showed the inhibitory growth of Staphylococcus epidermidis. The average value of the inhibition zones of the single extract samples of ketepeng cina, sambang darah, ruku-ruku, avocado seed, bungli, pacar air, and sungkai resulted in inhibition zones of 6.28±0.20 mm, 7.90±0.31 mm, 2.30±0.37 mm, 3,53±0.50 mm, 4.35±0.52 mm, and 4.69±0.17 mm, respectively. Furthermore, the combination of methanol extract of ketepeng cina leaves (C. alata) with the six selected plants extract in an average diameter of inhibition zone greater than the average diameter of the inhibition zone of each extract. However, the average diameter of the inhibition zone of the combined extract was not more significant than the sum of the diameter of the inhibition zone of each extract. The conclusion of this study is the combination of the methanol extract of ketepeng cina leaves (C. alata) with six selected plant extracts has an additive/indifferent effect in inhibiting the growth of S. epidermidis.

Abstract

The methanol extract of sambang darah leaves (Excoecaria cochinchinensis L.) contains flavonoids, saponins, tannins and triterpenoids which have the potential as antibacterial compounds. The goal of this research is to produce liquid soap that preparations with four formulas by varying the methanol extract of sambang darah leaves as the active ingredient, characterizing, and understanding its antibacterial activity. Organoleptic tests, foam stability, pH, specific gravity, and viscosity were all used to characterize liquid soap. The best results were obtained with liquid soap formulation 3 (3 g extract), which had foam stability of 84.10%, a pH of 9.62, specific gravity of 1.03 g/mL, and viscosity of 492.933 cP. The organoleptic test revealed that the liquid soap was a homogeneous viscous liquid with a blackish-brown color and a characteristic extract odor. The inhibition zone for antibacterial activity against Staphylococcus aureus and Escherichia coli was 9.15 mm and 13.72 mm, respectively. In antiseptic tests, all soap formulas reduced bacteria on the thumb.

Abstract

The Real Work Lecture is a community service program that aims to practice the Tri Dharma of Higher Education. One way students can help overcome problems in the community is by devoting themselves to the community through Community Service Lectures (KKN). The purpose of this study is to learn how Real Work Lectures contribute to increasing environmental awareness and providing education to children in Mangunjaya Village, Bekasi Regency. This study uses an observation method and this study contains a description of the planning process and implementation of Real Work Lecture activities. The subject of the implementation of the Community Real Work Lecture in Mangunjaya Village RT 006/RW 003. The results of the study show that environmental awareness in Mangunjaya Village has increased significantly as a result of the Real Work Lecture, even though there are some conditions that are less than ideal, the community is still happy to participate in the KKN program designed by students, there are no obstacles in the preparation, implementation and evaluation of programs that are planned and held according to the previous plan such as reading and writing, counting, playing, saving can be carried out well. In this activity, the manufacture and installation of directional signs as well as appeal banners are carried out through cooperation, coordination and participation. The community is beginning to realize how important it is to keep the environment clean and healthy. Children also better understand the importance of saving and increasing their knowledge through educational learning provided by Real Work Lecture students. It is hoped that this program can provide insight to the community about the potential and development of the village.
