Abstract

Daun dari tumbuhan ungu telah dikenal mempunyai sifat antioksidan. Sifat antioksidan ini disebabkan oleh keberadaan senyawa metabolit sekunder golongan fenolat. Flavonoid merupakan senyawa golongan fenolat terbesar yang ditemukan di alam. Warna ungu dari daun ungu memperlihatkan bahwa sifat antioksidan berasal dari senyawa golongan flavonoid. Hal ini menimbulkan ketertarikan untuk mengukur kadar fenolat dan flavonoid yang dimiliki oleh daun ungu yang diambil dari Mentawai. Metode yang digunakan dalam penentuan kadar fenolat dan flavonoid masing-masing adalah metode Folin Ciocalteu dan aluminium klorida. Daun ungu diekstraksi secara maserasi menggunakan pelarut etanol dilanjutkan dengan fraksinasi menggunakan pelarut kloroform, etil asetat, dan air. Hasil pengukuran kadar fenolat ekstrak etonol dan fraksi (kloroform, etil asetat, dan air) berturut-turut adalah (65,6;37,44;106,98;52,3) mgGAE/gram ekstrak. Hasil pengukuran kadar flavonoid ekstrak etanol dan fraksi (kloroform, etil asetat, dan air) berturut-turut adalah (45,7;42,9;50,7;43,5) mgRE/gram ekstrak.

Abstract

Kemumu (Colocasia gigantea cv) is a type of taro whose stems and leaves are edible. Kemumu belongs to the type of taro whose properties and phytochemical content, in particular, have not been widely reported. This study aims to determine the phytochemical content of kemumu stem as well as antibacterial bioactivity test and cytotoxic test (anticancer initial test) which can be used as raw materials for natural medicine. The stem is extracted using three types of solvents with different levels of polarity, n-Hexane, Ethyl acetate, and Ethanol. Antibacterial activity test uses agar diffusion method with some 20%, 40%, and 60% concentrations. Cytotoxic activity was tested by the Brine Shrimps Lethality Test (BSLT) method. Phytochemical test results are known that the kemumu extract contains secondary metabolites such as flavonoids, alkaloids, tannins, terpenoids, and steroids. The ethyl acetate extract contains flavonoids, tannins, terpenoids, and steroids. Antibacterial activity was found in ethyl acetate extract with a concentration of 40% with an inhibition zone of 17.5 mm. The highest LC50 value was also in the ethyl acetate extract of kemumu, which was 7.14 ppm. This value indicates a high level of toxicity so that ethyl acetate extract of kemumu acts as an antibacterial and anticancer.

Abstract

The resident in RT 001/ RW 013, Pasie Nan Tigo Subdistrict, Padang City generally has used the groundwater for daily need but that groundwater can not be used for the drinking, washing the clothes and for a bath because the water looked turbid, sandy and unpleasat odor. If the water condition like these conditions, it is usually caused by the overlimit of iron and manganese level in that water. Based of that problems we made natural water filter to treat that water by using sands, gravel, palm fiber, coconut shell charcoal in household scale. The purpose of this study is to know the effectiveness of natural water filters to remove the iron and manganese in the ground water. Natural filter material used in this study was arranged with varying thichnesses. As for determining the levels of iron and manganese in the sample carried out by the method of National Indonesian Standar 06-6989.4-2004 and 6989.5:2009. The results of three groundwater sample tests before and after filtering showed the reducing iron and manganese levels namely 58,21 % and 91,58 %. The value of iron and manganese in the sample after being tested is still below the quality standart for drinking water.

Abstract

The β-cyclodextrin glucosyltransferase (β-CGTase) enzyme is an extracellular enzyme that converts starch to cyclodextrins. Cyclodextrins are widely used in the pharmaceutical industry, one of which is to increase solubility. This enzyme is produced by bacteria, especially the genus Bacillus sp. BTS3A, BTS3B and CK-2 isolates that produce CGTase enzymes have been isolated from the soil of cassava and potato plantations. The bacteria are fermented in liquid Horikoshi media, then centrifuged at 4 ° C and then concentrated by freeze dry. The enzyme was purified by the ammonium sulfate precipitation method up to 59.61% for BTS3A, 59.6% for BTS3B and 58.1% for CK-2. Then dialyzed using a cellophane membrane with cut off 14 KDa in phosphate buffer. The cyclization activity of crude enzymes was characterized by varying incubation times of 30, 60, 120 minutes and incubation temperatures of 30 ℃, 37 ℃, 55 ℃. CGTase cyclization activity was measured based on the decrease in phenolphthalein absorbance at a wavelength of 550 nm. The β-CGTase enzyme from the three isolates showed the optimum percentage reduction at 55°C for 30 minutes incubation

Abstract

Ground water pollution can be caused by various kinds of wastes and the results of human activities. Ground water containing COD, BOD and other harmful substances in high concentrations must pass through a treatment before use. Activated carbon is free carbon with an internal surface that has good absorption. One alternative to wastewater and groundwater treatment systems that is economical, does not require a large area and is easy to operate is the Multi Soil Layering (MSL) system. This study aims to determine the effectiveness of activated charcoal sources in reducing COD, BOD, heavy metal content and increasing groundwater pH. Sampling using random sampling technique. The MSL system uses a variety of activated charcoal sources, namely coconut shells, rice husks and sawdust. The results showed that the source of activated charcoal which gave the most effective increase in pH was rice husk (53.57%). In other hand, the sources of activated charcoal that decreased COD, BOD, Hg, Pb, and Fe were sawdust (31.16%), rice husks (73.16%), coconut shells (70.75%), sawdust (26.74%), sawdust (46.94%), respectively. The best source of activated charcoal in reducing pollutant content in groundwater is sawdust.

Abstract

ABSTRACT Jering skin is a solid waste that can cause problems if not treated seriously because it pollutes the environment. Based on previous research, the potential possessed by jering skin is very high because it contains flavonoids and polyphenols which are antiseptic, and antioxidant, also has a very toxic toxicity value for shrimp artemia salina, this has the potential as an anticancer. Therefore, this study aims to continue testing other activities, namely by conducting antidiabetic activity tests using the methanol solvent fraction. The method used is to use a Microplate reader or platec reader at a wavelength of 410 nm to determine absorbance, so that with data analysis the Inhibitor Concentration value of 50% (IC50) of sample extracts is inhibited by the α-glucosidase enzyme in hydrolyzing the p-nitrophenyl substrate. -α-D-glucopyranoside (p-NPG) to form glucose. The results of the study obtained an IC50 value of 387,6091 µg/mL. When compared with IC50 values ​​for positive root as a positive control of 0.8135 μg / mL, it is still weak because the root is a pure composition while the Methanol Faction still contains Rough extract still in the fractionation but the dry skin Methanol fraction can be needed as a source to be used as a substitute for further as a joint exploration of antidiabetic in jering skin. Keywords: Jering, Methanol, Antidiabeti, IC50. ABSTRAK Kulit jering merupakan limbah padat yang dapat menimbulkan masalah bila tidak ditangani dengan serius karena mencemari lingkungan. Berdasarkan penelitian sebelumnya, potensi yang dimiliki oleh kulit jering tersebut sangat tinggi karena mengandung senyawa flavonoid dan polifenol yang bersifat antiseptik, dan antioksidan, juga memiliki nilai Toksisitas yang sangat toksit terhadap udang artemia salina hal ini berpotensi sebagai antikanker. Oleh karena itu, penelitian ini bertujuan untuk melanjutkan uji aktivitas lainnya yaitu dengan melakukan uji aktivitas Antidiabetes mengunakan fraksi pelarut metanol. Adapun metode yang digunakan adalah dengan mengunakan Microplate reader atau platec reader pada panjang gelombang 410 nm untuk menentukan absorbansi, sehingga dengan analisis data diperoleh nilai Inhibitor Concentration 50% (IC50) dari ekstrak sampel dalam menghambat kerja enzim α-glukosidase dalam menghidrolisis substrat p-nitrofenil-α-D-glukopiranosida (p-NPG) untuk membentuk glukosa. Hasil dari penelitian diperoleh nilai IC50 adalah sebesar 387,6091 µg/mL. Jika dibandingkan dengan nilai IC50 untuk akarbose sebagai kontrol posistif sebesar 0,8135 µg/mL, memang masih lemah karena akarbose merupakan senyawa murni sedangkan Fraksi Metanol masih berupa ekstrak Kasar walaupun sudah di fraksinasi namun fraksi Metanol kulit jering dapat dikatakan memiliki potensi untuk dilakukan isolasi lebih lanjut sebagai eksplorasi senyawa aktif antidiabetes dalam kulit jering. Kata Kunci : Jering; Metanol; Antidiabetes; IC50.
