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

One common domestic waste in the waters is detergent residue due to the daily habit of washing clothes. Thus, wastewater treatment is needed to purify the water. One of the methods is photocatalytic degradation. In this study, TiO2 nanoparticles were used to degrade methyl ester sulfonate (MES), one of the raw materials for making detergents. This study aims to investigate the effect of TiO2 concentration, reaction time, and light source on the MES degradation. The variations of the degradation tests included photocatalyst concentrations of 0.5, 1, and 1.5 mg/L, irradiation times of 1, 2, and 3 hours, and UV lamps and sunlight. The residual surfactant in water was analyzed using the Methylene Blue Active Surface (MBAS) method. The principle of this method is that MES will bind to methylene blue to form a complex blue compound so that its concentration can be quantified using a UV-Vis spectrophotometer. This study showed that the higher photocatalyst concentration increased the surfactant degradation from 11.97% to 33.91%, and the longer the degradation time, the more surfactant was degraded up to 41.56% after 3 hours. The sunlight source produces 55.72% degradation, more than a 10-watt UV lamp. The MES degradation follows the second-order reaction equation with a rate constant of 0.0963 L/mg.hour.

Abstract

Plastic is a material that is widely used for the manufacture of various products. Plastic industrialization continues to be developed to meet human needs but this also has a negative impact. Plastic industrialization produces plastic waste which is a source of environmental damage. Plastic waste that can only decompose in a long time is not friendly and even becomes a threat to environmental sustainability. Departing from these problems, development and research related to plastic products that are able to provide added value but are environmentally friendly are continuously carried out. One example of the development of bioplastics is the research and development of biodegradable plastics for food packaging which contain antimicrobial properties. The application of antimicrobials to biodegradable plastics can be an added value because environmentally friendly plastic packaging can simultaneously maintain and protect food from being easily damaged or spoiled. Various kinds of antimicrobial agents have been studied, especially regarding their respective abilities against bacteria which are a source of food spoilage. This study uses a literature study on bacteria regarding descriptions and explanations and antimicrobial ingredients derived from organic and inorganic materials that are not harmful to health.

Abstract

Shallot skin (Allium cepa var. aggregatum) contains secondary metabolites of flavonoid, phenolic, and saponin that can be antibacterial. This research was conducted by extracting the shallot skin using maceration and ultrasound-assisted methods with 3, 5, and 7 days for maceration extraction and 10, 20, and 30 minutes for ultrasonication-assisted extraction (UAE). The extract was then tested for phytochemical screening and analysis of its flavonoid, phenolic, and saponin levels. Three extracts with the best secondary metabolite compounds were then tested for the inhibitory power of the extracts against Escherichia coli through the diffusion method. The results showed that shallot skin extract contained flavonoid and phenolic compounds but not saponin. Based on the analysis of the levels of these compounds using UV-Vis spectrophotometry, three extracts with the highest flavonoid and phenolic content were obtained from maceration extraction for seven days, the UAE method for 20 minutes, and the UAE extraction method for 30 minutes. The extract using the UAE method has relatively higher flavonoid and phenolic content (6.93 and 2.59 ppm, respectively) than the extract using the maceration method (5.48 and 2.46 ppm, respectively), which is also considered more efficient in terms of time. A preliminary antibacterial activity test showed antibacterial activity in the shallot skin.

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.
