Abstract

Silver nanoparticle, Ag0, is a broad spectrum antimicrobial agent with a very low risk of resistance. In this study, silver nanoparticles, Ag0, were synthesized through the spontaneous reduction of Ag + solution using a natural reducing agent of lemon peel extract. Extraction was carried out at 60oC for 10 minutes in a water solvent. The extraction of lemon peel involves varying the mass of the lemon peel powder, namely 2.5; 5; 7.5; and 10 grams to produce varying concentrations of reducing agents. Synthesis of silver nanoparticles was carried out at 60oC for 20 minutes by mixing 0.1 M Ag + solution with the extract solution with various concentrations. The result of the synthesis is a dark brown to blackish colloidal solution which indicates the formation of Ag0 from micro to nanoparticles in the solution. The concentration of lemon peel extract is directly proportional to the amount of Ag0 formed, which is characterized by the colour of the solution. The Ag0 solution showed its effectiveness as an antifungal under five days of observation. The Ag0 solution also exhibits highly effective antibacterial properties based on testing against E. coli. ‘

Abstract

Eceng gondok (Eichhornia crassipes) merupakan gulma perairan yang dapat mengganggu ekosistem air.Untuk mengurangi dampak negatif yang ditimbulkan berbagai upaya telah dilakukan dan salah satunya adalah dengan pemanfaatan eceng gondok sebagai bahan bakupembuatan Carboxymethyl Cellulose (CMC).Potensi eceng gondok sebagai bahan bakuCMC cukup besar karena kandungan selulosanya yang cukup tinggi. Proses pembuatan CMC ini diawali dengan isolasi selulosa eceng gondok. Selulosa yang dihasilkan kemudian dialkalisasi dengan menggunakan larutan NaOH 10% b/v dan 35% b/v. Tahap berikutnya adalah reaksi karboksimetilasi antara alkali selulosa  dan natrium monokloroasetat (NaMCA, ClCH2COONa) dalam suatu media reaksi. Pada penelitian ini digunakan campuran larutan isopropanol dan isobutanol sebagai media reaksi dengan variasi komposisi. Dari hasil penelitian diperoleh CMC dengan kondisi optimum pada konsentrasi NaOH 10% dengan nilai derajat substitusi (DS) tertinggi sebesar 1,49pada komposisi isopropanol-isobutanol 20:80 (v/v), kemurnian tertinggi 90,9% pada komposisi isopropanol-isobutanol 80:20 (v/v), dan viskositas tertinggi 157,5 cPpada komposisi isopropanol-isobutanol 50:50 (v/v).

Abstract

Indonesia is one of the world's largest tin-producing countries, but its downstream industry is not well developed. One of the chemical products derived from tin is SnCl4.5H2O. Several commercial production routes are reviewed in this paper. In addition, SnCl4.5H2O characterization techniques from advanced analytical instruments to titration analysis are also discussed. Commercial applications of SnCl4.5H2O products include catalysts, polyvinyl chloride (PVC) stabilizers, and dyes. The latest developments regarding the potential of SnCl4.5H2O as a catalyst are also reviewed in this paper.

Abstract

This study examines the effect of UV irradiation on the yield and physical characteristics of biodiesel from candlenut oil using a TiO2-K2O/natural zeolite composite. Natural zeolite was activated with KOH and impregnated with TiO2. The formed composite was analyzed with an X-ray diffractometer. Biodiesel was synthesized with candlenut oil to methanol molar ratio and catalyst loading (w/w oil) 1:4, 1:6, 1:8, and 2, 4, and 6%, respectively. The XRD analysis shows peak patterns of anatase and rutile TiO2, K2O, and zeolite. UV light can increase biodiesel yield, with the highest yield at 82.08% at oil to methanol molar ratio of 1:8 and a catalyst loading of 2%. The physical properties of biodiesel are in accordance with national standard SNI 7182:2015. GCMS results shows that the main components of fatty acid methyl ester from biodiesel are methyl oleate, methyl palmitate, and methyl linoleate.
