Journal of Physics: Conference Series 2020年第1期1500卷

作者： Muhammad Yerizam Suri Andayana Utari Oktavia Industrial Chemical Technology Study Program / Chemical Engineering Sriwijaya State Polytechnic Palembang Indonesia

This research aims to determine the optimum conditions with variations in temperature and concentration of Lactic Acid Bacteria (BAL) starter in fermentation in the process of making mocaf flour. Fermentation of cassava is carried out using a fermenter equipped with a thermo controller and tubular heater. Heater is used to increase the temperature connected to the temperature controller (thermo controller) so that the fermentation process runs in optimum conditions and get good quality of mocaf flour according to SNI 7622-2011 standards. The fermentation process was carried out anaerobically with and varying the temperature of 30 and 33°C and the concentration of the lactic acid bacteria starter were 0.06%, 0.12%, 0.18%, 0.24% and 0.3% with fermentation time during 24 hours. The results showed optimum conditions of cassava fermentation at a temperature of 33°C and lactic acid bacteria starter concentration of 0.3% obtained mocaf flour protein levels of 12.87%.

Acid Mine Drainage (AMD) poses significant environmental challenges to water resource management. This review explores the potential of waste materials in developing nanocomposites for AMD treatment. The study highlights the benefits of using agricultural residues, industrial byproducts, and municipal solid waste as components in nanocomposites. These waste-based nanocomposites offer cost-effectiveness, resource conservation, and transformation of waste into valuable assets. The mechanisms of pollutant removal, recent trends, and advancements in nanocomposites for AMD treatment are discussed. Unlike previous studies, this work provides a pioneering comprehensive assessment of waste-derived nanocomposites, systematically synthesizing state-of-the-art advancements while critically evaluating their practical application and ecological impact. Recommendations for optimizing nanocomposites include material selection, property tailoring, and field implementation. Future research directions are proposed, such as advanced characterization techniques, novel waste material exploration, and ecological impact evaluation. Harnessing waste material potential can promote sustainable water and waste management, restoring AMD-affected environments and protecting water resources.

Red Kupang (Musculista senhausia) is one of the fisheries resources included in the bivalve class. Red Kupang is commonly found in the waters of Surabaya, Sidoarjo, Pasuruan, and the coast of the Madura Strait. The nutritional components contained in red mussel meat include 75.48% water content, 1.93% ash content, 15.02% protein, 6.17% fat, and 1.41% carbohydrate. The nutrient content of red mussels that can be utilized is protein. So that red mussels can be used as an alternative source of animal protein. For this reason, this research is carried out namely isolation of proteins against red mussels. Isolation can be carried out by means of extraction, where the pH and time of extraction affect this process. The research began with washing and drying the red mussels at 40oC until a constant weight (± 6 hours) was obtained. The second stage is making red mussel flour with 60 mesh particle size. The third step is the isolation of red mussel protein by extraction process that is 50 grams of red mussel flour homogenized in aquadest with a ratio of 1:10 w / v, then extraction is carried out at an alkaline pH (pH: 9, 10, 11, 12 and 13). at a temperature of 40 oC using a hot plate stirrer for 10, 20, 30, 40 and 50 minutes. The results obtained the best conditions at pH 11 and 50 minutes extraction time with a protein content of 72.70%.

Indonesia is the third largest country on the global paddy rice production and also considered as a rice importer. Even, Indonesia has the biggest per capita consumption of paddy rice (140 kg of paddy rice per person per year). Product diversification using local commodities. Artificial rice is potential to be developed as a new value product using different types of grains. It is one of appropriate solutions for reducing imported rice rate. Artificial rice was produced using high nutrition composite flours (modified cassava starch, corn, Canavalian ensiformis, and Dioscorea esculenta). This study consists of three main stages, preparation of composite flour, formulation, and artificial rice production using hot extruder capacity 10 kg/day. The objectives of this studies were to investigate some formulation in compare with commercial paddy rice. Artificial rice has been successfully conducted using prototype of hot extruder with the temperature 95°C. Physical analyses (color and water absorption) were carried out to artificial rice product and commercial paddy rice. chemical analyses (nutrition and amylose content) of product will be also presented in this study. The best formulation of artificial rice was achieved in 80% modified cassava starch, 10% Canavalian ensiformis, and 10% Dioscorea esculenta, respectively. © 2018 The Authors, published by EDP Sciences.

引用

IOP Conference Series: Earth and Environmental Science 2020年第1期506卷

作者： C Irawan M W Ramadhan I F Nata M D Putra Chemical Engineering Study Program Engineering Faculty Lambung Mangkurat University Banjarbaru South Kalimantan Indonesia

A study was done on treatment of raw water sources for drinking water using chitosan/Mg-Al LDH (CS/Mg/Al–LDH) composites by adsorption process. An analysis on the adsorbent characterizations of FTIR, SEM and XRF showed that the CS/Mg/Al–LDH had many different functional groups and a high specific surface area for adsorption processes. The CS/Mg/Al–LDH showed high adsorption uptake capacity and selectivity for iron (Fe), turbidity, and colour in the raw water sources for drinking water in Municipal Waterworks in Banjarmasin. Therefore, the CS/Mg/Al–LDH composites have the potential to be used as an adsorbent in water and wastewater treatment.
