These subjects are usually fostered by teachers in the fields of Chemistry, Biology, and Physics. The chairpuson of the Padang City MGMP chemistry teachers sent the letter to LP2M through chemistry department to give training enterpreneural material. This is due to the lack of chemistry entrepreneurship teaching materials in schools that can be used as a reference in the implementation of PKWU subjects. The solution offered is training in processing vegetable materials into economically valuable products as a form of entrepreneurship for Padang City MGMP chemistry teachers, so that they can help implement PKWU learning for chemistry teachers in schools. The Community Service Team of the Department of Chemistry FMIPA UNP has provided entrepreneurship-based applied chemistry training, particularly in the processing of vegetable materials into economically valuable products as a form of entrepreneurship for MGMP Chemistry teachers in Padang. The training provided is considered effective in improving the abilities and skills of MGMP Chemistry teachers in Padang City in processing vegetable materials into various economically valuable products. Chemsitry teachers can be applied in PKWU learning in senior high school.

Abstract

Coumarin has been isolated and characteritated from rind of Citrus nobilis Lour by maseration methode with methanol. After fractionation by n-hexane and ethyl acetate, collected the phase ethyl acetate which positive of coumarin. From ethyl acetate extract coumarin have been isolated by column chromatography. The isolation results was obtain 2,159 g of pure white needle-shape crystalline with the melting point of 126,2-127,60C. Structure of the isolated coumarine was elucidated by spectroscopic methodes, UV-Vis,13C-NMR, 1H-NMR, 2D-NMR (DEPT/HSQC, COSY, NOESY, HMBC) and IR spectra. Based on the spectra data the isolated coumarine is marmin.

Abstract

Ruku-ruku leaves are used to remove distinctive odors from fish in some cuisine of West Sumatra. The characteristic odor comes from secondary metabolites especially essential oils. Therefore, secondary metabolites in ruku-ruku leaves have the potential to be further investigated as a source of bioactive compounds. The phytochemical screening of ruku-ruku leaves is a preminilary qualitative test that needs to be done to maximise its function as a medicinal plant. Based on the result data, there are some different result of flavonoid, steroids, and triterpenoids identification. Ruku-ruku leaves from Pesisir Selatan and Padang Panjang shows less flavonoid compounds tham Payakumbuh, Batusangkar, and Lubuk Alung. Both of this city and Payakumbuh also gives less steroids and triterpenoids. The factor influencing this result is caused by several factors, namely temperature, humidity, light exposure, and salinity.

Abstract

Endophytic fungi are microorganisms that live in plant tissues without harming the host plant. One of the plants that have potential as a host for endophytic fungi is the flower of the bitter plant (Andrographis paniculata) which contains secondary metabolites and has biological activity. The purpose of this study was to obtain fungal isolates and identify the content of secondary metabolites and antibacterial activity. The results of the isolation of endophytic fungi produced isolates of endophytic fungi with isolate code BS. Microscopic observation of BS isolates belonging to Chrysosporium spp. The results of the phytochemical test of the ethyl acetate extract were positive for terpenoid compounds marked with a pink color and the FTIR spectrum containing a dimethyl gem group. BS extract also could inhibit the growth of all test bacteria, namely E. coli and S. aureus at concentrations of 1%, 3%, and 5%.
