Abstract

Groundwater is one of the alternative water sources commonly used by the community to meet its clean water needs. However, the presence of Fe in groundwater under conditions exceeding the threshold should be a concern, considering the potential dangers associated with long-term consumption. Therefore, this study was conducted to investigate the application of the electrocoagulation method in reducing the Fe content in groundwater. Additionally, the study will investigate the extent of the effect of adding aeration during the electrocoagulation process, as well as the impact of filtration and sedimentation on the post-electrocoagulation water. This research was conducted using a continuous system with voltage variations of 5, 10, and 15 V. The sampling times were 15, 30, 60, 90, and 120 minutes, with a flow rate of 33.3 ml/min using aluminum plates as electrodes. The results show, for each variable, that the iron concentration is below the specified threshold of 0.3 mg/L and can be reduced by up to 99.61%.

Abstract

Rising global obesity rates demand the development of low-calorie food options. This study explores the potential of starfruit, a fruit low in fat and energy, as a substitute ingredient in ice cream. Using a Completely Randomized Design (CRD) with three different formulas (F1, F2, F3) based on starfruit juice concentration, the research analyzed the sensory, nutritional, and antioxidant characteristics of the final product. The sensory test results showed significant differences in color and aftertaste attributes, with formula F1 (20 grams of starfruit juice) selected as the best. Per 100 grams, the F1 ice cream has a low nutritional content: 126 kcal of energy, 4.2 g of protein, 2.6 g of fat, and 21.6 g of carbohydrates. The nutritional contribution per serving is well below the Daily Reference Values (DRV), making it an effective low-calorie food choice. However, its antioxidant activity is very weak, with an IC50 of 8275 ppm. Overall, starfruit-substituted ice cream offers an innovative solution for low-calorie foods.

Abstract

This study aims to produce biodiesel from Refined Bleached Deodorized Palm Oil (RBDPO) using a heterogeneous catalyst based on calcium oxide (CaO) derived from limestone andmodified with palm oil mill fly ash (FA) as a catalyst support. The limestone feedstock was first activated to obtain the CaO catalyst. Subsequently, the FA material was activated through calcination at 500°C. The CaO-FA catalyst was synthesized using the wet impregnation method and then calcined at 600°C. This catalyst was applied in the transesterification of RBDPO with methanol at various molar ratios. The study investigated the effect of different CaO-FA catalyst compositions (1:1, 2:1, and 3:1), and methanol:RBDPO molar ratios (8:1, 10:1, and 12:1) on biodiesel yield. The results demonstrated that both the CaO-FA catalyst ratios and the methanol:RBDPO molar ratios significantly influenced the biodiesel yield and the resulting Fatty Acid Methyl Ester (FAME) composition. Gas Chromatography-Mass Spectrometry (GC-MS) analysis revealed that the 3:1 CaO-FA composition with an 8:1 methanol:RBDPO molar ratio produced biodiesel with the highest methyl palmitate (C17H34O2) content of 88.99%, which meets the characteristics of high-quality biodiesel. These findings provide valuable insights into the development of CaO-FA-based heterogeneous catalysts for cost-effective and environmentally friendly biodiesel production, in line with government initiatives to promote renewable energy utilization.

Abstract

Harmful pollutants found in waste include the heavy metal Cu (Copper). Methods that can be used to reduce the heavy metal content of copper include the adsorption process. This adsorption methods was chosen because this process does not produce toxins and the raw materials for adsorbent are more economical such as corn cobs. Corn cobs have a carbon content of 43,42% and have a sufficiently high porous structure. This research aims to determine a compatible mathematic model on the process of adsorption of Cu waste with corn cobs bioadsorbent. The process of making bioadsorbents uses star fruit organic matter as an activator to increase absorption of copper heavy metals. The copper heavy metal adsorption process is carried out by adding the bioadsorbent to artificial liquid waste with adsorbent mass variations of 2.5, 5, 7.5, 10, 12.5 grams and varying harvesting times from 40 to 120 minutes. The results of the analysis using the Atomic Absorption Spectrophotometry (AAS) method revealed that the percentage of copper metal absorption by the best bioadsorbent is 89.55%. This percentage was observed with an adsorbent mass addition of 12.5 grams and a contact time of 120 minutes. Based on the calculations of the mathematical model of heavy metal Cu adsorption by activated carbon from corn cobs using the Langmuir Isotherm model, the resulting equation is y = 0.5497x + 9.968 with a value of R²= 0.994.

Abstract

The tofu industry in Indonesia significantly contributes to the national economy but also poses environmental challenges due to the liquid waste it generates. This wastewater contains organic and inorganic pollutants such as BOD, COD, TSS, and pH levels that do not meet effluent quality standards, potentially harming aquatic ecosystems. This study aims to evaluate the effectiveness of a photocatalytic process using titanium dioxide (TiO₂) and hydrogen peroxide (H₂O₂), activated by artificial UV-C light and sunlight, in reducing pollutants in tofu industrial wastewater. The treatment was conducted with a fixed concentration of 50 mg/L TiO₂ and 140 mL H₂O₂ per 1000 mL of wastewater, with contact times ranging from 30 to 60 minutes. Results showed that the TiO₂-H₂O₂ combination reduced COD by up to 84.78%, BOD by 76.75%, and TSS by 78.37%, while increasing the pH toward acceptable limits. The optimal degradation occurred under sunlight exposure for 60 minutes. This method offers a promising, eco-friendly, and cost-effective wastewater treatment solution.

Abstract

Cacao (Theobroma cacao L) is a plant that produces 75% of waste in the form of fruit peels. Cacao pod husk contains coarse fiber, cellulose, hemicellulose, and lignin so it has the potential to be used as an adsorbent. Textile liquid waste generally contains dyes that are difficult to decompose and have the potential to pollute the environment, one of which is methyl orange (MO) which is toxic and mutagenic. This study aims to evaluate the effectiveness of cacao peel as a bioadsorbent in the elimination of MO from liquid waste. The adsorption process is carried out using a packed column with a cacao bed weight of 100g. The initial concentration of the MO waste feed used is 5 ppm with an operating temperature at room conditions between 25 - 27oC. In this study, the influence of flow rate and pH was studied. The best results were compared to cacao bioadsorbents activated using the alkaline method. The results showed that the optimal conditions were achieved at a flow rate of 25 ml/min and pH 7 with an adsorption capacity of 19.81 × 10⁻⁵ mg/g. Cacao bioadsorbent with alkaline activation is able to increase the surface area and pore volume of the adsorbent, so that the adsorption capacity increases even though the activation residue has an effect on the chemical oxygen demand (COD) and total suspended solid (TSS) values.

Abstract

The utilization of used cooking oil as a biodiesel feedstock is hindered by its high free fatty acid (FFA) content, which interferes with the transesterification process. This study aims to reduce FFA levels through adsorption using a silica–cellulose-based microsponge adsorbent synthesized from rice husk ash and corn cob waste. The investigated process variables include adsorbent mass (1, 3, 5 g), temperature (30, 45, 60 °C), contact time (30, 60, 90 minutes), and silica-to-cellulose ratios (40:60, 50:50, 60:40). FTIR analysis revealed characteristic peaks of Si–O–Si (~1053 cm⁻¹) and Si–O (~795 cm⁻¹) indicating the presence of amorphous silica, while the O–H stretching (~3200–3500 cm⁻¹) of cellulose appeared weaker due to silica dominance on the surface. This confirms the successful formation of the silica–cellulose composite with strong chemical interaction. Furthermore, Brunauer–Emmett–Teller (BET) analysis showed a specific surface area of 87.77 m²/g with mesoporous characteristics, confirming the microsponge structure with high affinity toward polar molecules such as FFA. The optimum conditions were obtained at 5 g adsorbent mass, 30 °C, 60 minutes contact time, and a 60:40 silica-to-cellulose ratio, achieving an FFA reduction efficiency of 49.62%. These physicochemical properties make the adsorbent efficient, energy-saving, and environmentally friendly, highlighting the great potential of agricultural waste transformation into active materials for pre-purification of used cooking oil toward sustainable biodiesel production.

Abstract

The increasing accumulation of non-degradable plastic waste has  encouraged the development of sustainable construction materials. This study examines the physical and mechanical performance of paving blocks manufactured from plastic waste using plastic–sand compositions of 100%, 75%, 50%, and 25% based on the sand weight. The production process includes melting the plastic, mixing it with sand, compressing the mixture, and testing based on SNI 03-0691-1996. Compressive strength increases with a higher plastic content, with the 75% plastic mixture reaching 11.64 MPa, followed by 100% plastic at 10.82 MPa, while the 25% mixture reaches only 8.91 MPa. Water absorption decreases as plastic content rises, with the 100% plastic mixture showing the lowest value (0.27%) and the 25% mixture the highest (3.78%). Abrasion resistance was recorded highest in the 100% plastic mixture, with wear values of 0.037- 0.062 mm/min. Based on SNI 03-0691-1996, the use of high plastic proportions was found to enhance the wear resistance and mechanical performance of the paving blocks, thereby demonstrating the significant potential of plastic waste as a sustainable construction material

Abstract

The fractionation plant of PT Perta-Samtan Gas Sungai Gerong separates hydrocarbon components from Natural Gas Liquid (NGL) into Liquefied Petroleum Gas (LPG) products that comply with the specifications of SK Ditjen Migas No. 116.K/10/DJM/2020. One key unit in this process is the De-Butanizer Column, which separates butane from lighter fractions. This study analyzes the effect of reboiler temperature variation on the composition of the LPG mixed and on energy efficiency in the distillation system. The simulation was performed in Aspen HYSYS V.14 using the Peng–Robinson equation of state and was based on actual operating data from the plant’s Distributed Control System (DCS). The results show that decreasing the reboiler temperature increases the propane (C3) content while reducing butane (C4) in the LPG mixed, with some butane carried over to the bottom product due to a lower boil-up rate. The optimal condition was found at 279.1 °F: at this temperature the LPG mixed still met quality standards while heat-flow consumption decreased by 460,491.74 kJ/h, resulting in annual energy savings of approximately Rp 321,073,593.25. This analysis concludes that operating the reboiler at a lower temperature can enhance energy efficiency without compromising product quality, thereby offering significant economic benefits to the company.

Abstract

Natural rubber (NR) and Nitrile Butadiene Rubber (NBR) exhibit poor miscibility due to their differences in their solubility parameters. To improve compatibility, a PAN-co-PMMA compatibilizer was synthesized by copolymerizing acrylonitrile (AN) and methyl methacrylate (MMA) with potassium persulfate (K2S2O8) as the initiator. This study investigates the influence of initiator concentration on the characteristics of PAN-co-PMMA and evaluates the mechanical performance of NR/NBR blends incorporating the compatibilizer for rubber seal applications. PAN-co-PMMA was synthesized using a water-ethanol co-solvent at 65°C for 3 hours with a stirring speed of 400 rpm, using initiator concentrations of 1, 2, 3, dan 4 %wt and an AN: MMA ratio of 90:10 (%wt). The drying was conducted at 100°C for 3 hours. IR analysis confirmed successful copolymerization through the appearance of characteristic C≡N and C=O absorption bands. The addition of PAN-co-PMMA reduced curing time and significantly enhanced the tensile strength of the NR/NBR blends.
