Abstract

Scientific literacy is the ability that students must have to analyze and apply science concepts in solving everyday life problems. Students’ scientific literacy on peatlands can be acquired by students from daily interaction with peatlands, understanding that comes from parents and the community, as well as from learning in the classroom. This study aims to analyze the scientific literacy skills of students from several campuses in Borneo on the topic of peatlands. In this study, scientific literacy is described into scientific knowledge and scientific competencies domain. The research was conducted using a survey method with 528 respondents from several universities in Borneo, Indonesia. Research results show that even half of the respondents live around the peatland area, students’ scientific literacy is in the low category. The students’ scientific competencies need serious attention. A proper learning resources and comprehensive learning is needed to improve student overall scientific literacy.

Abstract

Research about chromatographic profile of antioxidant and antibacterial compounds in n-hexane fraction of Libo leaves (Ficus variegata Blume.) has been done in order to know the form of chromatographic profile of antioxidant and antibacterial compounds in n-hexane fraction of Libo leaves. Extraction was done by maceration using methanol. Isolation was done by 2 methods, vacuum liquid chromatography (VLC) then followed by conventional column chromatography. Eluent used are n-hexane-ethyl acetate and methanol-chloroform. The results based on conventional column chromatography are as many as 10 fractions. The fractions are being conducted then by a qualitative testing of the antioxidant activity using DPPH method and antibacterial activity test using bioautography TLC method. The results formed as a chromatographic profile of fraction that contain antioxidant and antibacterial activity, which are as many as 5 fractions (NHB1, NHB3, NHB4, NHC1, NHC3) active as an antioxidant and 4 fractions (NHB1, NHC1, NHC2, NHC3) which are active as an antibacterial. The secondary metabolite contents of the fractions are alkaloid, flavonoid and steroid/terpenoid.

Abstract

Chalcone is an intermediate compound as the main precursor for the biosynthesis of flavonoid in plants. Chalcone has been known to have variety of different pharmacological activities. The difference in chalcone activity is influenced by the differences of subtituents found in both aromatic rings on the chalcone stucture. This study performed the synthesis of 2',4'-dichloro-4-hydroxy-3-methoxychalcone compound from the raw material of 2,4-dichloro acetophenone and vanillin by Claisen-Schmidt reaction using conventional method by stirring. The yield of synthesized compound is 91.57% of purity. The synthesized compounds were characterized by structural elucidation methods using IR, MS, 1H-NMR and 13C-NMR. Toxicity and antioxidant activity tests were performed on the synthesized compound. Base on the test results obtained LC50 value of 20.04 ppm and IC50 26.10 ppm. It is better to describe the pharmaceutical potential of 2',4'-dichloro-4-hydroxy-3-methoxychalcone little bit further.

Abstract

Uncaria is a genus of plants that are widely distributed in the tropics. There are about 5 of the 38 species of this genus growing in the tropical rain forests of East Borneo, Indonesia. For a long time, Uncaria is commonly used as a traditional medicine to treat various diseases by the Dayak tribe in Kalimantan, traditional people believe that Uncaria may be cured cancer, tumors, mioms, and cycts. Based on previous studies, the activity of the genus Uncaria has been widely reported such as cytotoxic, antimicrobial, antioxidant, antidiabetic, and thrombolytic activities. This article aims to summarize the potential of the Uncaria genus, focusing on 5 species from East Borneo, namely Uncaria nervosa, Uncaria longiflora, Uncaria gambir, Uncaria tomentosa and Uncaria cordata. The method used in this article is a literature study by collecting previous research articles related to the Uncaria genus. The results of the literature study show that the Uncaria genus in East Borneo has many secondary metabolites with diverse chemical structures that show good biological potential so that they can be used as broad and promising insights for drug discovery and development. This paper is also expected to provide input for the policy of conservation of medicinal plants in the forests of East Borneo.

Abstract

Tumbuhan Libo (Ficus variegata Blume.) memiliki buah yang tidak dimakan oleh hama/serangga, hal ini diduga karena kandungan metabolit sekunder tumbuhan libo mengandung senyawa aktif yang dapat berpotensi sebagai antibakteri maupun antioksidan. Penelitian ini bertujuan untuk mengetahui profil kromatografi senyawa antioksidan dan antibakteri, serta mengetahui golongan metabolit sekunder yang terdapat dalam fraksi aktif etil asetat daun libo. Sampel dimaserasi dengan pelarut metanol. Isolasi dilakukan sebanyak 2 kali yaitu dengan cara kromatografi cair vakum kemudian dilanjutkan dengan kromatografi kolom konvensional. Hasil pemisahan berdasarkan kromatografi kolom konvensional yaitu diperoleh sebanyak 16 fraksi. Dari hasil tersebut kemudian dilakukan pengujian aktivitas antioksidan terhadap DPPH dan pengujian aktivitas antibakteri terhadap bakteri uji dengan metode KLT Bioautografi. Hasil penelitian diperoleh profil kromatografi fraksi etil asetat daun Libo (Ficus variegata Blume.) aktif sebagai antioksidan terhadap DPPH, dan aktif terhadap bakteri, Eschericia coli dan Staphylococcusaureus. Golongan metabolit sekunder aktif fraksi etil asetat daun libo adalah alkaloid, steroid, terpenoid dan fenol.
