Abstract

The growth of the textile industry, including the Sasirangan textile industry, is increasing yearly, producing large amounts of liquid waste. Generally, this wastewater is discharged into the environment without treatment, becoming a source of environmental pollution. Therefore, it is crucial to reduce these pollutants. Various methods, not only physical and chemical but also biological methods, are available to remediate wastewater. Phytoremediation has provided an economical, environmentally friendly, and aesthetic solution to remediate wastewater. This study aimed to utilize the Water Hyacinth plant as a phytoremediator and determine its effect in reducing Total Suspended Solid and colors in the liquid waste of the Sasirangan textile industry. This research begins by preparing Water Hyacinth plants. Next, the characterization of Water Hyacinth roots using FTIR and SEM. Finaly, the acclimatization of water Hyacinth, followed by a phytoremediation process for 15 days. Based on the results of the characterization of Water Hyacinth roots with FTIR, it shows that Water Hyacinth roots contain functional groups O-H strain, C-H vibrations, C=O strain, C-H deformation, and C-O stretching. Observations with SEM showed that the roots of Water Hyacinth were extremely unstructured and had pores. However, it has cavities which are pores in cellulose. The significant decrease in Total Suspended Solid was at 9 days of phytoremediation, which was 54 mg/L (71.12% removal). The optimum color reduction within 9 days of phytoremediation was 81.5 PtCo (92.26% removal). The presence of these functional groups and pores, strengthened by the analysis of Total Suspended Solid and colors, showed that Water Hyacinth could reduce levels of Total Suspended Solids and colors in the Sasirangan textile wastewater.

Abstract

Electrocoagulation process on batik-modified sasirangan textiles wastewater treatment used aluminum electrodes (Al6061-T6) from the waste scraps of the aluminum furniture industry. Batch experiments at room temperature were carried out at an initial of pH 4. The parameters effect such as time reaction (5– 120 min), current density (3.5–5.5 mA/cm2), and the distance between the electrodes (2–5 cm) were evaluated to determine the optimum condition for COD and BOD5 removal. The optimum condition for the electrocoagulation process on batik-modified sasirangan textiles wastewater was selected at a time of 15 minutes, 5.5 mA/cm2 of current density, and 2 cm of electrode distances. Under those conditions around 59.60% of COD and 62.47% of BOD5 removal efficiencies were achieved. Both kinetics in COD and BOD5 removal with electrocoagulation reaction follows the half-order reaction. Reusing the leftover aluminum from furniture manufacturing as electrodes in the electrocoagulation process is quite effective for treated batik-modified sasirangan to meet the quality standard of clean water

Abstract

The manufacture of the Sasirangan home textile industry involves coloring and dyeing processes using synthetic dyes in large quantities. These contaminants of dyes and organic materials would cause high color and chemical oxygen demand (COD) contaminants values. This study aims to characterize the wastewater of batik-modified Sasirangan and determine the effect of current density and length of operating time on color removal and reduction of COD in Sasirangan home textile industry wastewater through the batch electrocoagulation process. The method used in this research is an electric current flowing in the same direction to the Sasirangan home textile industry wastewater in a reactor with dimensions of 310  180  240 mm3. The electrode used is aluminum alloy type 1100. The aluminum/aluminum (Al/Al) electrode is used in this electrocoagulation (EC) process, then connected to a direct current (DC) power supply. The experiment was carried out at room temperature using an electrode distance of 2 cm with variations in the time of the electrocoagulation process for 15–120 minutes. The experiment was repeated for variations in pH (4–9) with a current density of 3.5–5.5 mA/cm2. Furthermore, an analysis of the color removal and the decrease in the concentration of COD was carried out. The results showed that the contaminant content in Sasirangan home textile industry wastewater decreased significantly, whereas the optimal conditions for the EC reaction were determined using color and COD removal efficiency parameters. The decrease in color and COD concentrations occurred at a current density of 5.5 mA/cm2 with a pH of 4 for 120 minutes, around 1110 PtCo and 90.4 mg/L of COD, respectively

Abstract

Coal is the main fuel used to make clinker in the cement industry. As time goes by the cost of purchasing coal is getting higher and supplies are running low, making it necessary to optimize to reduce production costs. To deal with this problem, high-quality coal is mixed with low-quality coal (lignite coal) using the Chevron method. The Chevron method is a method of stacking coal continuously along the pile axis and moving horizontally in a predetermined area. The coal is stacked in layers with layers of low-quality coal (lignite coal) and high-quality coal alternately according to the lignite coal mixture ratio. The specified ones are 30%, 40%, 50% and 60%. The optimum mixture ratio of low-quality coal (lignite coal) is 60%, which can reduce the cost of purchasing coal by IDR. 486,899 per ton. Daily consumption of coal for burning clinker is around 1000 tons per day so the efficiency of coal purchasing costs reaches around 14.6 billion rupiah per month while maintaining the quality of the clinker produced with a free CaO range of 1.04 – 1.40%, below the Indonesian National Standard (SNI ) namely 1.50%.

Abstract

Studies on hydrocracking of nyamplung oil into biofuel have been studied using the HZSM-5 catalyst. The HZSM-5 catalyst was modified into HZSM-5 mesopore and impregnated using transition metals namely Cobalt, Nickel and Cuprum with a metal loading of 5% and a metal ratio ratio of 1:1:1. The resulting catalyst was then characterized using X-Ray Difraction (XRD), Brunauer Emmet Teller (BET), and Scanning Electron Microscope-Energy Dispersive X-Ray (SEM-EDX). The hydrocracking process was carried out in a batch reactor by adding 0.5 grams of catalyst and a volume of Nyamplung oil of 15 mL. The temperaturs used vary from 250, 300, and 350 oC with a hydrogen gas pressure of 20 bar, and a reaction time of 2 hours. The resulting biofuel product is analyzed using Gas Chromatography Mass Spectrometry (GC-MS). The resulting biofuel product has a compound composition of n-paraffin with an area % of 26.72%, cycloparaffin 3.34%, olefin 0.33%, aromatic compounds 15.83% and polycyclic aromatics 12.56%, with a conversion of 72.1% in temperatur 350 oC. Biofuel from nyamplung oil can be used as an alternative fuel to reduce dependence on fossil fuels through the hydrocracking process.

Abstract

Introduction: Astambul Subdistrict in Banjar Regency is classified as a flood-prone area. Such regions tend to experience a decline in clean water quality. In Astambul, no mapping has been conducted regarding clean water quality based on water management and land conditions to improve clean water quality in flood-prone areas. This study aims to analyze the availability of clean water sources in flood-prone areas using geoelectrical methods and Geographic Information Systems (GIS). Methods: This study used a quantitative research design with a cross-sectional method to analyze clean water sources using geoelectric and Geographic Information System (GIS) methods. This study was conducted in five villages in Banjar Regency, South Kalimantan Province. Testing using the geoelectrical method was conducted at five locations in five villages, while the GIS method was used at 30 locations across the five villages. Results and Discussion: The geoelectric method showed that 4 villages had turbid water quality, and 1 village had very turbid water. The GIS (Geographic Information System) method indicated that the parameters for turbidity, iron (Fe), manganese (Mn), and coliforms did not meet the standards. The average values of Dissolved Oxygen (DO), Total Dissolved Solids (TDS), Total Suspended Solids (TSS), and turbidity are 8.03 mg/L, 179.27 mg/L, 0.22 mg/L, and 17.23 NTU, respectively. The average values for pH, iron (Fe), and manganese (Mn) are 6.44, 0.68 mg/L, and 21.02 mg/L, respectively. Conclusion: Based on Geoelectric and Geographic Information System analysis, the Astambul District area has clean water sources that are still below quality standards.

Abstract

The composites of biopolymer chitosan obtained from the swamp fish scale with bentonite as clay minerals has been characterized by the structural, mechanical, surface functional group and composition properties using scanning electron microscopy (SEM), thermal gravimetric analysis (TGA), X-ray fluorescence (XRF) and X-ray Diffraction (XRD) analysis. The morphology structure obtained by SEM for the original chitosan, bentonite, and its composites showed that the particles are relatively well dispersed in the chitosan matrix. The physicochemical properties of the chitosan-bentonite composites depend significantly on the chemistry of the polymer matrices, the nature of bentonite, their modification, and the preparation methods that showed by SEM, TGA, XRF and XRD analysis. The obtained composite of chitosan bentonite was then applied for treating raw water sources of drinking water in Bilu river, South Kalimantan, during the dry season. The raw water sources contained a high value of turbidity (ca. of 370±30 NTU) and color (1300±150 Pt-Co). Batch experiment using the composite of chitosan bentonite for treating raw water sources was significant to reduce the value of turbidity, and the color becomes 24.8±2 NTU and 86.7±5 Pt-Co, respectively. The results then compare to the treatment using the commercial chitosan and bentonite self. Moreover, it found that the raw water treatment using the composite of chitosan-bentonite is more favorable than chitosan and bentonite materials.

Abstract

The Mn-Fe layered double hydroxide using chloride in the interlayer anion was successfully synthesizedusing chemical co-precipitation methods. The Mn-Fe LDH was then applied as adsorbent for arsenic removal from synthetic acid mine drainage. The adsorbent characterizations of SEM and XRD analysis showed that the Mn-Fe LDH had many different functional groups and a high specific surface area for the adsorption processes. The morphological structure of Mn-Fe LDH by the SEM-EDS analysis method shows a round shape structure with a particle size of about 1 m, and the XRF analysis method shows that the Mn and Fe elements dominate more than other components. Batch adsorption experimental conducted using the Mn-Fe LDH with the interlayer anion of chloride as an adsorbent to study the effect of contact time, equilibrium pH, and temperature on the arsenic removal. The Mn-Fe LDH showed high adsorption uptake capacity and selectivity for the arsenic in the synthetic acid mine drainage. The adsorption and ion exchange between interlayer chloride anions in Mn-Fe LDH and As (V) solution was the main adsorption mechanism. Therefore, the Mn-Fe LDH can be used as an adsorbent in water and wastewater treatment. In contrast, this research has the potential to be processed and developed into advanced materials.
