Abstract

Pada era industrial, limbah cair industri menjadi salah satu masalah yang serius. Limbah cair industri yang tidak sesuai dengan baku mutu dibuang secara langsung ke badan air yang mengakibatkan pencemaran lingkungan. Karenanya pengolahan limbah harus ditangani sejak awal selama proses produksi. Salah satu material yang sering digunakan sebagai adsorben dalam proses adsorpsi yaitu silika. Silika merupakan adsorben yang memiliki struktur geometri pori, sifat kimia pada permukaan dapat dimodifikasi dan sangat mudah diproduksi. Silika dapat diperoleh dari beberapa sumber diantaranya yaitu sekam padi dari limbah hasil pertanian. Review ini bertujuan untuk mengetahui kemampuan silika sebagai bahan pengolahan limbah industri. Silika dapat digunakan dalam proses pengolahan limbah cair beberapa industri sepeti batik, laundri, industri tahu dan beberapa limbah industri lainnya. Silika paling efektif diaplikasikan pada pengolahan limbah industri tekstil. Silika mampu mengurangi kekeruhan dan kadar warna limbah cair industri khususnya tekstil. Nilai koefisien penurunan tertinggi sebesar   96,86% untuk warna, sedangkan kekeruhan sebesar 99,31%. Nilai ini didapatkan dari berat campuran silika 5 gram (28,65 %wt), volume limbah 100% dengan kandungan warna 1,123 Co dan kekeruhan 180,5 NTU. Industrial liquid waste is one of the serious problems in the industrial era. Disposal of industrial liquid waste that is not in accordance with quality standards directly into water bodies can cause environmental pollution. Therefore, wastewater treatment must be handled early during the production process. Silica is one of the most commonly used adsorbents in the adsorption process. This is due to the ease with which silica is produced and the surface properties (pore geometry structure and surface chemistry) that can be modified. Silica can be obtained from several sources, one of which is rice husk which is a waste from agriculture. This review aims to determine the role of silica as an industrial wastewater treatment material. From several articles obtained, silica can be used in the processing of wastewater from batik industrial, laundri industrial, tofu industrial and several other industries. Silica is most effectively used in the textile industry wastewater treatment. Silica can reduce the color and turbidity of the textile industry wastewater. The highest removal coefficient value is 96.86% for color and 99.31% for turbidity obtained from a 5-gram (28.65 %wt) silica mixture mass, 100% waste volume with color content of 1.123 Co and turbidity of 180.5 NTU.

Abu batubara merupakan limbah hasil proses pembakaran batu bara yang komposisinya akan berbeda sesuai dengan jenis batubara yang digunakan dan proses pembakaran yang dilakukan. Salah satu komposisi  penyusun utama dari abu batubara ini adalah silika. Silika memiliki  potensi untuk dimanfaatkan dalam berbagai tujuan seperti untuk pengolahan limbah, untuk bahan aditif dalam pertanian, hingga sebagai nanosilika. Paper ini berisi informasi mengenai pemanfaatan silika dari abu batubara yang sudah ada serta metode yang efektif untuk mendapatkan silika dari limbah abu batu bara ini. Dari pembahasan diketahui bahwa studi pemanfaatan silika saat ini umumnya berfokus ke arah sintesis zeolite. Penelitian pemanfaatan silika sebagai nanosilika baru mulai dikembangkan baru-baru ini. Sementara itu, pemanfaatan silika tidak terlepas dari metode ekstraksi silika dari coal fly ash tersebut. Dari pembahasan diketahui NaOH masih menjadi pilihan utama dalam proses leaching silika. Studi ini diharapkan dapat memberikan informasi bagi kemajuan riset dalam rangkapengolahan dan pemanfaatan limbah. The use of coal as an energy source has not been replaced until now, subsequently the  studies on the utilization of coal fly ash still need to be developed. Coal fly ash is waste from the coal combustion process whose composition will differ according to the type of coal used and the combustion process carried out. One of the main constituents of coal ash is silica. Silica has the potential to be used in various purposes such as for waste treatment, for additives in agriculture, to nanosilica. This paper contains information on the utilization of silica from existing coal fly ash and an effective method for obtaining silica from the coal fly ash. Based on the discussion, it is known that the current study of the use of silica generally focuses on the synthesis of zeolite. The research on the use of silica as nanosilica has only recently been developed. Meanwhile, the role of silica is related to the method of extracting silica from the coal fly ash. It is known that NaOH is the main leaching solution in the case of silica leaching process. This study is expected to provide information for research progress in the context of processing and utilizing waste.

Abstract

Coconut has been known for its benefits in human life. Coconut coir, as part of coconut which is considered as waste, contains useful components. It contains high cellulose which is could be used in fiber industries. Meanwhile, coconut coir also contains lignin which needs to be separated. In this study, a delignification process was used to remove the brown color on the fiber caused by the lignin content. The delignification process was a pretreatment before the cellulose extraction was carried out. It had been done in the various NaOH concentration (0.5; 1; and 1.5 M), reaction time (1; 1.5; and 2 hours) and the reaction temperature (60,70, and 80 oC). This study aims to determine the cellulose content and the factor that affected the cellulose extraction and the characteristics of the cellulose extracted from the coconut coir. The Chesson Data method and SEM analysis have been used for the characterization of the cellulose. The delignification method known has the potential as a simple and effective method for extracting cellulose from natural materials. The result shows that the optimum cellulose content obtained at 100 mesh coir particle size, 1.5 M NaOH concentration, at 80°C for 1.5 hours was 69.82 %.

Abstract

The residue of thermal power plants is known as coal fly ash and has been considered solid waste pollution worldwide. The characteristic of coal fly ashes showed that it contains several components that could be utilized in several fields. One of the potential utilization is in the agricultural application. This study analyzed the characteristic of two different types of coal fly ashes and their effect on the soil. The x-ray fluorescence (XRF) analysis resulted that SiO2, Al2O3, Fe2O3, CaO dan MgO are the five major components in the soil, and both coal fly ash, CFA A and CFA B. This XRF analysis result concluded that coal fly ashes have great potential to be a substitute for silica fertilizer. Then, the effect of the coal fly ash addition also was studied by the moisture content and nutrient (N, P, and K) content characteristics in the soil and the soil-ash mixture. The findings indicated that the addition of 125 grams of coal fly ash A had a greater impact on the soil compared to fly ash B when 250 grams of soil was used.

Abstract

Advancements in science and innovation in the modern world have led to a growing demand for materials in the production of goods. The utilization of materials in the manufacturing process has been reduced. This is due to the heaviness, costliness, susceptibility to corrosion, and complex assembly systems of metal materials compared to natural fibers. One of the materials currently under development is composites. Composites are a mixture of at least two materials that vary in shape, chemical structure, and are non-disintegrating. The aim of this study is to explore the fabrication and influence of rice husk volume fraction in epoxy composites, as well as to test their tensile strength and composite characteristics. The methodology involves preparing the raw materials (rice husk charcoal, epoxy resin, epoxy hardener, and silicon spray), rice husk charcoal preparation, epoxy production from resin and epoxy hardener, and composite manufacturing with volume fractions of 10%, 20%, and 30% following ASTM D-638 standards. The testing of composite characteristics through tensile tests yields varying tensile strengths. The highest tensile strength is found in composites with a volume fraction of 10%, while the lowest tensile strength is found in composites with a volume fraction of 30%.

Abstract

The side of the production of the Gunung Kidul Cocoa Fermentation Center, DIY, in the form of cocoa pod husk, can cause a buildup of rubbish and become a nest for fungi that cause disease. Maximizing the use of cocoa shell waste is an effort so that people can increase the use value of waste into products that have higher economic value, one of which is extracting the cellulose. Cellulose fiber has several advantages such as good mechanical properties, low density, environmentally friendly, abundant, cheap, non-toxic, easily degraded, and included in renewable natural resources. Cellulose is obtained through an extraction process with two stages, namely alkaline delignification and bleaching. Therefore, this research aims to utilize the potential of cocoa pod husk in cellulose extraction for optimum conditions for the bleaching process with NaOCl 5%, 8%, 10% and 12% through analysis of yield, water content, ash content and FTIR characterization. Based on research that has been carried out, optimum results for cellulose are obtained through bleaching NaOCl 8% which has the best level of lightness and a yield of 52%. Chesson datta characterization also shows that cellulose NaOCl 8% NaOCl has the lowest water content and ash content, namely 1.4% and 0.8% respectively. FTIR analysis shows that the optimum results have the -OH stretching functional group as a representation of cellulose at wave numbers 3206 cm-1, 3442 cm-1 and 3600 cm-1. The presence of a peak in the wave number indicates that the bleaching process has succeeded in isolating the cellulose in the cocoa pod husk.
