Abstract

Activated carbon is a well known as porous material, with large specific surface area, which is useful in adsorption of both gases and solutes from aqueous solution. In this research, prepraration of activated carbon was through chemical activation of palm shells using KOH as an activator. Preparation of carbon from palm shell were the first carbonized in a furnace at temperature of 400 - 500 °C. Carbon is soaked in KOH activator solution for 8 hours and then carbonized at a temperature of 600 - 800 °C. The activated carbon obtained was characterized by XRD, SEM and FTIR. Characterization using SEM shows that activated carbon has pores and using FTIR shows the presence of several functional groups such as hydroxyl (-OH), carboxyl (-COOH), carbonyl (-C=O) that can be used for adsorption. Adsorption studies were carried out using batch experiments with synthetic naphthol and remazole dye solutions. The adsorption study was carried out in batch, based on isotherm assumptions and following Langmuir isotherm model. These results indicate that palm shell activated carbon has the potential used as an adsorbent for removing naphthol and remazole dyes from the solution.

The effect of graphite mass in TiO2 semiconductors on the efficiency of Dye-Sensitized Solar Cell (DSSC) based on dye extract of Melastoma malabathricum has been investigated. This study aims to determine the effect of mass variations of graphite-TiO2 on the efficiency of DSSC and bandgap produced in the manufacture of DSSC. The mass variation of graphite added in TiO2 semiconductors is 10%, 12%, 14%, and 16% of the mass of TiO2. The result shows the maximum wavelength (λmax) for anthocyanin at 544 nm with an absorbance of 5.7 Á. The calculation results obtained by the optimal bandgap value in the variation of graphite mass 14% is 3.15 eV. The results of characterization using XRD obtained tetragonal TiO2 crystal structure with a particle size of 49.8 nm. The DSSC test results obtained optimal results found in mass variations of 14% graphite with a current strength of 140,001 μA, a voltage of 1446.9 mV, and DSSC efficiency of 0.2026%.

Abstract

This study aims to analyze the effect of the residence time of water jasmine plants in the form of genjer (Limnocharis flava) on its effectiveness in reducing the parameters of acidity (pH), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Suspended Solid (TSS) and ammonia in domestic wastewater. The method used is an experiment with a Completely Randomized Design (CRD) design. The initial parameters of domestic wastewater showed pH 8.7, BOD5 209 mg/l, COD 412.73 mg/l, TSS 105 mg/l, and ammonia 45.22 mg/l. The results showed that the decrease in pH ranged from 4.21% to 17.62%, the decrease in BOD5 between 46.19% to 88.27%, the decrease in COD between 23.39% to 79.23%, the decrease in TSS between 76.22% to 79.25%, and the decrease in ammonia between 33.50% to 79.28%. The use of genjer plants in artificial wetlands with different residence times proved effective in reducing all these parameters, with a residence time of 9 days showing the most optimal results in reducing all parameters.

Abstract

The COVID-19 pandemic has increased online shopping and food delivery, causing a surge in single-use plastic waste and has become a habit to this day along with the rapid development of digital technology. Dream Central Waste Bank (BSI Dream) in Wijaya Pura Village collects 3 tons of waste monthly but lacked advanced plastic processing technology. This community service initiative aimed to implement a pyrolysis reactor to convert plastic waste into fuel oil and paving blocks, thereby enhancing economic value while promoting environmental sustainability. The activity stages included partner coordination and surveys, reactor performance upgrades, operational training, and evaluation. This activity involved five partners representing the Wijaya Pura Village community.  The reactor successfully produced fuel oil (density: 0.848–0.912 g/mL) and residues suitable for paving block production. The outcome of this initiative demonstrated improved skills among partners, the creation of marketable products and increased community income opportunities. Furthermore, the activity fostered greater awareness of the importance of sustainable waste management and supported the application of circular economy principles.

Abstract

This research aimed to produce magnetites from the residue of iron sand extract solution in HCl and the effect of silica encapsulation on the magnetite used XRD, SEM and FTIR characterization tools. The crystal size tended to increase in the magnetite encapsulated by silica (K (6%), L (9%), N (24%) and O (36%), because the perfect condensation and hydrolysis of the encapsulation material, while the M sample (12%) decreased the crystal size of 17.41 nm because the hydrolysis and condensation of the sample did not occur completely. The crystals in magnetite before and after being encapsulated with silica did not change. The transmittance of the typical functional groups of magnetite (Fe-O) and the typical functional groups of silica (Si-O-Si) tends to decrease after encapsulation with silica which caused the infrared absorbance of the molecules to increase high so that the presence of magnetite and silica is higher in the silica encapsulated sample The effect of variations in silica concentration on SEM characterization results is reduced agglomeration, particles that coincide and stick to the sample as the silica concentration increased with the smallest particle size found in the M sample (12%), namely the range of 10-50 nm. The residue of the iron sand extract solution with HCl can form nanomagnetites with an average particle size range below 100 nm.

Abstract

The use of activated carbon in Indonesia is increasingly expanding in line with the increasing demand for activated carbon, so it is necessary to develop activated carbon preparation using many raw materials and activators. Activated carbon from the shell of  rubber fruit using H3PO4 as activator has been synthesized  for adsorption of Pb (II) metal ion. The objective of this research is to find out the best concentration of H3PO4 activator on the activation of activated carbon of rubber shell, to know its ability as Pb (II) metal ion absorbent in solution and to know the characteristics of activated carbon. Parameters observed included activator concentration, pH and initial concentration of adsorbate. The results showed that the optimum activator concentration on preparation of activated carbon from the rubber shell was H3PO4 20% with the Pb(II)efficiency adsorption of 98,20%, while the optimum pH found at 4 with the adsorption capacity of 87,48% . The adsorption capacity increases with the concentration of adsorbate up to 30,73 mg/g at a concentration of 175 ppm. Activated carbon from rubber shell activated with H3PO4 has moisture content 9,22%, moisture content of 23,53%, ash content of 10,27% and carbon bonded 66,20% fulfilling the requirements of SNI 06-3730-1995 . The results of morphological analysis and carbon constituents using SEM-EDX showed that activated carbon contained 93,91% carbon element and Pb element concentration contained in activated carbon after adsorption of 1,13%.
