Abstract

Pengembangan penelitian tentang material berbasiskan sumber daya alam lokal dan dapat diperbaharui terus dikembangkan akhir-akhir ini. Hal tersebut didasari adanya kebutuhan material baru dengan karakteristik yang lebih menguntungkan dan dapat digunakan pada aplikasi yang spesifik. Penelitian ini bertujuan untuk mempelajari preparasi membran alginat-polietilen glikol (AP-PEG) dan aplikasinya sebagai enkapsulan. Alginat yang digunakan adalah hasil ekstraksi dari rumput laut cokelat Padina sp. Dengan metode maserasi jalur asam alginat. Preparasi membrane alginat Padina sp.-polietilen glikol (AP-PEG) dilakukan dengan perbandingan PEG-AP = 1:5; 1:10; 1:15; 0:1 (b/b). Analisis gugus fungsi terhadap seluruh membran yang dihasilkan, menunjukkan bahwa membran AP-PEG yang dihasilkan diprediksi sebagai hasil blending secara fisika karena tidak ada gugus fungsi baru yang terbentuk. Membran dengan perbandingan berat PEG-AP=1:15 memiliki karakteristik terbaik dengan persentase swelling sebesar 1465,5%, stress sebesar 14,588 MPa, strain 0,07 dan Modulus Young sebesar 193,13 MPa. Hasil analisis morfologi menunjukkan bahwa banyak rongga ditemukan pada membrane tersebut. Hasil uji disolusi terhadap membrane tersebut menunjukkan bahwa, pada pH 1,2 membran tersebut dapat melepaskan vitamin C sebesar 78,12% selama 60 menit dan tidak mengalami cracking. Di sisi lain, pada pH 7,2 membran tersebut dapat melepaskan vitamin C sebesar 83,54% dan cracking terjadi dalam waktu 12 menit. Hasil penelitian ini menunjukkan bahwa komposit AP-PEG dapat dibuat dari rumput laut coklat dan memiliki kemampuan sebagai enkapsulan.   Alginate Padina sp.-Polyethylene Glycol (AP-PEG) Membranes: Preparation, Characterization and Their Application as Encapsulant. The development of research on materials based on local and renewable natural resources has been continuously being developed recently. This is based on the need for new materials with more favorable characteristics and can be used in specific applications. This research aims to study the synthesis of alginate-polyethylene glycol (AP-PEG) membranes and their application as an encapsulant. The alginate was extracted from the brown seaweed Padina sp. by maceration method using alginic acid pathway. Alginate Padina sp.-polyethylene glycol (AP-PEG) alginate membrane was prepared with a ratio of PEG:AP = 1: 5, 1:10, 1:15 and 0:1 (w/w). The functional group analysis showed that the resulting AP-PEG membranes were predicted as a result of physical blending due to no new functional groups are formed. The membrane with a weight ratio of PEG:AP = 1:15 had the best characteristics, with a percentage of swelling of 1465.5%, stress of 14.588 MPa, 0.07 strain, and Young Modulus of 193.13 MPa. Morphological analysis showed that the membrane obtained had many cavities. The dissolution test showed that the AP-PEG membrane was able to release vitamin C of 78.12% for 60 minutes at pH 1.2 and no cracking was observed, while at pH 7.2 the membrane was able to distribute vitamin C by 83.54% and cracking occurs within 12 minutes. The results of this study indicate that AP-PEG composites can be made from brown seaweed and have good encapsulant capabilities.

Abstract

In this work, bismuth silicate-titania has been synthesized in two stages by utilizing bismuth oxynitrate as an elemental source of bismuth, oil palm leaves (OPL) as a source of silica and titanium tetraisopropoxide (TTIP) as source of titania (TiO2). In the first stage,bismuth silicate/silica (Bi4Si3O12/SiO2) was formed, which occurs due to the in-situ decomposition of palm leaves and reacts directly with the bismuth precursor at high temperatures (900oC). The reaction could possibly occur through a solid-state reaction mechanism between bismuth oxide and silica or through a more complex mechanism within the reaction mixture. The resulting product then reacts with TTIP, which is added and heated at the same temperature to form Bi4Si3O12/SiO2-TiO2 (bismuth silicate/silica-titania). Characterization of the as-prepared product using X-ray diffraction showed the dominance of bismuth silicate and small amount of titania (TiO2). As a result, TiO2 could not be detected in the diffractogram. Nevertheless, an analysis using energy-dispersive X-rays showed the presence of titanium elements in the resulting composite. The results of this study can be used to develop ternary metal oxides based on natural resources and agricultural wastes, such as oil palm leaves.

Abstract

The aqueous extract of Sapindus rarak (S. rarak) was produced by heating its rinds in demineralized water at 80 °C. The main experiment was conducted at room temperature by mixing a solution of sodium thiosulfate with the extract obtained previously. After adding dilute hydrochloric acid (10%), fine granules gradually formed in the solution and precipitated when the reaction was stopped and allowed to stand for 24 h. The analysis results showed the consistency of the X-ray diffraction (XRD) peak of the obtained material with sulfur standards. When looked at the surface using scanning electron microscopy (SEM), sulfur was found to be cube-shaped. The formation of cuboidal elemental sulfur possibly occurs due to the covering of thiosulfate ions and elemental sulfur during and after the reaction. Organic compounds were found covering sulfur through elemental and functional group analyses using energy-dispersive X-ray (EDX) and Fourier-transform infrared (FTIR) spectroscopy, respectively

Abstract

A new synthetic procedure is described for the synthesis of calcium silicate derivatives, using natural resources such as eggshell (ES) for calcium and oil palm leaves (OPL) for silica, which do not require prepurification. The reaction is performed by directly converting two weight ratio of the precursors, ES:3OPL and ES:6OPL, to dried-powder form by heat treatment at 900 °C for two hours. The results demonstrate that the concentration of the precursors has an effect on the morphology and crystallinity of the calcium silicate derivatives, mainly Ca2SiO4 and CaSiO3. X-ray diffraction results reveal that the reaction product obtained using a 1:3 ratio is quite pure, and mainly consisted of calcium silicate in the form of Ca2SiO4. The CaSiO3 was also identified in ES:6OPL, together with a small amount of excess non-reacted crystalline silica. Furthermore, a scanning electron microscopy analysis shows that both reaction products have a coarse surface. Copyright © 2020 by Authors, Published by BCREC Group.

Abstract

In this study, we developed an alternative of 4-nitrophenol reduction mediated by silver nanoparticles (AgNPs) which was synthesized using aqueous extract of the Peronema canescens leaf through an eco-friendly approach. The reducing 4-nitrophenol to 4-aminophenol mediated by AgNPS in the presence of sodium borohydride as a hydrogen source proceeded rapidly at room temperature without any additional treatments. The AgNPS synthesis was simple and was carried out under mild conditions. Ultraviolet–visible spectroscopy was performed to examine the properties of the obtained AgNPs, which displayed an absorption peak at 431 nm. A transmission electron microscopy analysis revealed that the AgNPs were spherical in shape and had an average particle size of 19 nm as determined by particle size analysis.

Abstract

The intriguing pursuit of environmentally friendly solvents with tailored properties for diverse applications is a focal point of numerous studies, encompassing precursor selection, thorough characterization, and the exploration of potential applications. The study aims to assess the physicochemical properties and antimicrobial activity of deep eutectic solvents (DES) produced from N,N-dimethyl urea (DMU) and citric acid (CA), highlighting differences from their individual precursors. Various mass ratio variations of (DMU, solid) and (CA, solid) (DMU:CA = 1.0:1.0; 1.0:1.5; 1.0:2.0; 2.0: 1.0; 1.5:1.0) have been tested to make DES solvents through the melt process. Both types of blends generally melt at a temperature of 80°C. The overall liquid resulting from the melting of solids was generally clear in color. Molecular analysis using an infrared spectrophotometer showed some insignificant shifts from one product to another, compared with DMU and CA as precursors. Likewise, analysis using a UV–Vis spectrophotometer, when the entire sample was dissolved in demineralized water (2 mg/mL), showed no difference in the spectrum. In addition, functional group analysis using a spectrophotometer showed some minor changes, mainly shifts in peaks due to changes in the DMU:CA ratio. This may be due to the interaction of the hydrogen donor and the hydrogen acceptor in DES. All samples showed absorption peaks in the ultraviolet region of 202-210 nm. The resulting DES application showed growth inhibitory activity for Staphylococcus aureus and Escherichia coli bacteria in all products produced. The same analysis of the two types of precursors used showed that only CA had activity, but DMU did not have similar activity.
