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.

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

Grape (Vitis vinifera) cultivation is hampered by a lack of suitable land and challenging nurseries. Use of crimson yellow podzolic soil for vine cuttings can be suboptimal. Although podzolic soil has a low capacity to absorb macro- and micronutrients and an acidic pH, it can nevertheless be used as a growing medium. A synthetic growth regulator (ZPT) bath of naphthalene acetic acid (NAA) needs to be added to the local red master grape variety, which has started to develop as a scion in nurseries. In order to assess the impacts of NAA-soaked concentrations on podzolic soil media and identify the morphological traits of local Red Master grape cuttings, this study set out to identify these traits. Its goal was to find out how auxin affected the development and yield of grapes (Vitis vinifera L.) grown in red yellow podzolic soil. A non-factorial totally randomized design with one factor (NAA concentration) was used in the study, with a block of 4 treatments and 3 repetitions. The varied NAA concentrations used in the treatment procedure included F0 (0 g L-1), F1 (2 g L-1), F2 (4 g L-1), and F3 (6 g L-1). The variables that were observed included the number of shoot bursts, the timing of leaf emergence, the number of sheet leaves, the length of the tendrils, and the proportion of live cuttings. ANOVA was used to tabulate and analyze observational data at a 5% level, and DMRT analysis was used to continue the analysis at the same level. According to the results, soaked NAA at a concentration of 0 g L-1 (S0) as the control treatment had the best results for the variable number of shoots and leaves, while a concentration of 2 g L-1 (S1) had the best results for the variable length of tendrils. However, soaked NAA had no significant impact on the variable when leaves emerged. Soaking auxin at the bottom of cuttings had no effect on shoot formation. Reduction of auxin due to defoliation can result in the expression of the isopentenyl-transferase (IPT) gene. Auxins, such as Indole-3-acetic acid (NAA), are usually involved in the regulation of root and leaf growth. If a plant has many leaves and few roots without the use of additional NAA or auxin, several factors may play a role, such as plant genetics, environmental conditions, and environmental stress. The use of additional NAA or auxin can explicitly affect the growth of roots and leaves. The survival percentage of cuttings is still low because it is influenced by the quality (material) of the cuttings, the age of the parent tree, growing media and water availability.

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

Coal ash, stemming from the combustion process in power plants, emerges as a potential pollution source due to its metal content. Recognized for housing various metals with environmental contamination potential, this study meticulously delves into the metal analysis of chromium (Cr) and lead (Pb) within four distinct samples of fly ash (FA) and bottom ash (BA) sourced from diverse coal-fired power plants across Indonesia. Employing the batch leaching method, the coal ash samples (FABA) underwent a 6-hour immersion in deionized water, replicating environmental scenarios akin to rainwater interaction with coal ash at disposal sites. XRF analysis scrutinized the chemical composition of each sample, while the leaching filtrate underwent analysis via pH meter and AAS to ascertain pH values and the concentrations of Pb and Cr. Results unveiled a substantial pH variation in the leachate, fluctuating from the initial deionized water pH of 7.00 to a range between 6.86 and 9.18. Notably, subsequent leaching indicated undetectable concentrations of Pb in all samples, with most exhibiting low Cr concentrations post-leaching, except for FA-2, FA-4, and BA-4, which displayed modest Cr concentrations. The scarcity or low concentrations of Pb and Cr post-leaching suggest an efficacious process inhibiting heavy metal release. This study offers profound insights into the chemical intricacies of coal ash, underlining its potential environmental ramifications. The absence of detectable heavy metal concentrations post-leaching underscores a minimal risk of environmental pollution, underscoring the imperative to comprehend the chemical reactions intrinsic to the leaching process for optimal waste management strategies.
