Abstract

Malarial parasite, Plasmodium, has been reported resistant to commonly used antimalarial drugs, such as chloroquin. Plants Artocarpus genus are known to have high content of flavonoids. One of interesting bioactivities of Artocarpus flavonoids is their antimalarial activity. This research is to investigate the potency of secondary metabolites in the heartwood and root bark of Artocarpus camansi Blanco as an antimalarial agent. Antimalarial activity from methanol extract of heartwood and roots bark of A. camansi were tested in vitro to Plasmodium falciparum SD7 (strain sensitive to chloroquin) and W2 (strain resistant to chloroquin) The extracts were also phytochcmically screened for compounds. The result showed that the methanol extract of heartwood and root bark of A , camansi Blanco inhibited the growth of Plasmodium falciparum 3D7 strain With IC50 values of 1.84 µg/mL and 32.13 µg/mL . respectively; While similar antimalarial activity test to Plasmodium falciparum W2 strain showed IC50 valucs of 8.11 µg/mL and 17.10 µg/mL, respectively. Phytochemical screening indicated that the heartwood and root bark of A. camansi Blanco contain flavonoids, terpenoids, and tannin, while coumarin and saponins are present only in the root bark of A. camansi Blanco.

Abstract

This research was aimed to identify some classes of secondary metabolite compound on the fractionation results of green bean extract (P. vulgaris L.) using Gas Chromatography-Mass Spectroscopy (GC-MS) method. Green bean was extracted by methanol solvent. Fractionation of methanol extract used Vacuum Liquid Chromatography (VLC) with some variation of eluents such as n-hexane 100%; n-hexane: ethyl acetate (9 : 1 to 1 : 9); and ethyl acetate 100%, produced 11 major fractions.  Based on Thin Layer Chromatography (TLC) analysis using DCM: MeOH (9.5: 0.5) as mobile phases, these 11 major fractions were classified based on their polarity such as non-polar, semi-polar and polar fraction. The results of identification by GC-MS spectrometer showed the presence of secondary metabolites such as monoterpenes in non-polar fraction; in semi-polar fraction was found terpenoids and steroids; in polar fraction was found monoterpenes, phenolic and steroid as the lowest percent area, that is less than 2%. Keyword: P.vulgaris L extract, fractionation, VLC, GC-MS

Abstract

Peel-Off face mask is one of the cosmetics that is used to treat skin from free radicals. Peel-off face mask can minimize the effects of free radicals because it contains antioxidant. One of the antioxidant sources is red dragon fruit’s rind (Hylocereuspolyrhizus Haw.). The aim of this study is to obtain Peel-Off face mask of red dragon fruit’s rind extract that contains anthocyanin. Red dragon fruit’s rind was macerated by ethanol 96%, ethyl acetate and n-hexane added citric acid (4:1) solvents. TLC test used Chloroform: ethyl acetate: n-butanol (5:4:1) eluent and sprayed by AlCl3. Antioxidant activity of extract was tested using DPPH (1,1-Diphenyl-2-Picryhidrazyl) method. Peel-Off face mask was made using PVA, HPMC, methyl paraben, propylparaben, propylenglycol, extract, ethanol 96% and aquadest. The rendemen of ethanol 96% extract was 9,476%, ethyl acetate extract was 0,783% and n-hexane extract was 0,631%. The results of TLC test showed yellow spots on the ethyl acetate and ethanol 96% extracts which indicated that extract contained flavonoids (anthocyanin). The results of antioxidant activity test showed that IC50 value of ethanol 96% extract was 189,7422 (AAI=0,2087), ethyl acetate extract was 196,9398 (AAI=0,2011), and n-hexane extract was 385,3664 (AAI=0,1027). The result of the product evaluations showed that all the formulas complied the product requirements such as the organoleptic, homogenity, pH, dispersive power and drying time. Peel-off face mask already meet the product requirements but further research is needed to test the product stability and activity.

Abstract

NTB Province is one of the areas prone to natural disasters. In 2018 there was an earthquake that destroyed infrastructure and the safety of human life. The number of casualties due to the earthquake, one of which is the lack of public knowledge about disasters. Through counseling, the increase in knowledge and capacity to reduce disaster risk in science master students at the University of Mataram. It is hoped that students as intellectual agents in the community can continue or inform their environment. Data collection methods: before and after counseling, students were given a questionnaire via google form sent via WA regarding a) disaster knowledge, b) disaster risk reduction capacity and c) disaster mitigation measures. The discussion is more devoted to earthquake disasters. Outreach was held on November 5, 2020 virtually via zoom meeting. The number of participants who took part was 45 people, consisting of 16 male students and 29 female students. The results show that it is not satisfactory, because the percentage increase in knowledge at the high level is still smaller than the percentage level at the lower level. Therefore, it is suggested that education about disaster risk capacity still needs to be disseminated.

Abstract

Penelitian ini bertujuan untuk mengembangkan instrumen berpikir kritis untuk mahasiswa kimia sebagai prototipe awal dalam pengembangan instrumen yang valid dan reliabel. Penelitian ini dilakukan dalam beberapa tahap yaitu analisis literatur terkait berpikir kritis, analisis materi kimia, dan analisis karakteristik mahasiswa kimia; menyusun butir soal sesuai dengan hasil analisis materi kimia dan karakteristik mahasiswa; rancangan awal instrumen berpikir kritis; uji internal untuk mendapatkan tanggapan terkait rancangan awal instrumen; dan revisi rancangan awal sesuai hasil uji internal. Praktisi yang terlibat sebanyak tujuh orang dan sebanyak tiga orang ahli di bidang pendidikan kimia. Hasil analisis literatur menunjukkan bahwa instrumen pengukur berpikir kritis menggunakan soal atau laporan penyelidikan; indikator berpikir kritis yang selama ini diukur: analisis, evaluasi, inference, deduksi, induksi, membuat asumsi, ketelitian, perencanaan eksperimen, mengembangkan hipotesis, dan menguji hipotesis; bentuk soal adalah pilihan ganda dan soal essay. Indikator yang ada pada soal kimia di UNRAM adalah ketelitian, menganalisis, dan mengevaluasi; instrumen berpikir kritis belum dikembangkan terutama dalam menguji kemampuan mahasiswa dalam membuat asumsi, mengembangkan hipotesis dan menguji hipotesis. Rancangan awal soal adalah soal pilihan ganda namun dilengkapi dengan alasan sebanyak 20 butir soal dengan indikator ketelitian, membuat asumsi, mengembangkan hipotesis, menguji hipotesis, dan mengembangkan kesimpulan. Hasil penilaian ahli dan praktisi menunjukkan bahwa instrumen telah memenuhi indikator berpikir kritis dan layak dilakukan ujicoba dengan beberapa perbaikan.
