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 growth of laundry services is directly proportional to the use of detergent. Detergent is a cleaning product that contains high levels of COD and phosphate. One method that can be used to overcome this problem is Multi Soil Layering (MSL). This research focussed on the flow rate's effect on decreasing pH, COD, and phosphate levels in industrial laundry waste. MSL was installed using a mixture of andosol soil and activated charcoal from coconut shells. Laundry wastewater was let into MSL with flowrate: 10, 50, and 100 ml/minute. The waste degradation system is placed anaerobically by optimising the anaerobic process in the andosol soil. The pH, COD, and phosphate levels were achieved at 7, 90.9%, and 80.7% by draining the laundry industry waste into the MSL system. This MSL method has a residence time of 266 minutes for a flowrate of 100 mL/minute, 532 minutes for a flowrate of 50 mL/minute and 2660 for a flowrate of 10 mL/minute.

Detergen merupakan produk pembersih yang mengandung COD dan fosfat dalam kadar tinggi. Salah satu cara yang dapat digunakan untuk mengatasi masalah tersebut adalah Multi Soil Layering (MSL). Penelitian ini berfokus pada pengaruh laju alir terhadap penurunan pH, COD, dan kadar fosfat pada limbah laundry industri. MSL dipasang menggunakan campuran tanah andosol dan arang aktif dari tempurung kelapa. Air limbah laundry dimasukkan ke dalam MSL dengan debit aliran: 10, 50, dan 100 mL/menit. Sistem degradasi sampah ditempatkan secara anaerobik dengan mengoptimalkan proses anaerobik di tanah andosol. Kadar pH, COD, dan fosfat dicapai pada 7, 90,9%, dan 80,7% dengan mengalirkan limbah industri laundry ke dalam sistem MSL. Metode MSL ini memiliki waktu tinggal 266 menit untuk laju alir 100 mL/menit, 532 menit untuk laju alir 50 mL/menit dan 2660 untuk laju alir 10 mL/menit.Kata kunci: MSL; Fosfat; COD; Industri Laundry; Tanah Andosol

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

Currently, the use of nanocellulose is very broad in various fields, such as pharmaceuticals, cosmetics, and electronics industries. In its development, this nano-sized cellulose is widely used as a reinforcement nanocomposite nanofiller. Nanocellulose has several advantages, including its large surface area, very lightweight, easy to shape, ability to break through the performance limits of conventional materials, and having a high economic value. Nanotechnology develops based on new properties produced by nanomaterials as advanced materials. Therefore, the factor of the extraction process method must be considered to produce nanocellulose that has good quality and large quantity. Nanocellulose extraction can be accomplished in a variety of ways depending on the raw material but is generally done through a combination of chemical, mechanical, and biological treatments.

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.
