Abstract

Disposable diapers are non-biodegradable waste that can pollute the environment. Disposable diapers contain super absorbent polymer (SAP) which has an absorption capacity of up to 1,000 times. SAP can be combined with activated carbon as a coating agent in urea slow-release fertilizer (SRF) production. This research aims to analyze the effect of urea SRF formulation (FA, FB, FC, and FD), with the combination of SAP and activated carbon, on the characteristics and nitrogen release behavior. SRF was characterized by Scanning Electron Microscope (SEM), Fourier Transform Infra-Red (FTIR), and Water Retention (WR) testing to determine the morphological structure, functional groups, and the ability of the sample to retain water during observation. The percentage of nitrogen release from SRF was calculated using the Kjeldahl method. The results of SEM characterization show that the thickness of the layer formed is about 63.5 µm. Different sample formulations affect the intensity of the functional groups produced. From all formulations, FD showed the highest WR and the lowest nitrogen release percentage with values of 80.2% and 20.4%, respectively. In general, it can be concluded that the combination of SAP from disposable diapers and activated carbon can be used as a coating agent in SRF production.

Abstract

Textile batik wastewater discharged into drains can contaminate groundwater and harm ecosystems and human health. This study focuses on reducing hazardous heavy metals in sewage through physical and chemical filtration. Heavy metals in the wastewater can poison aquatic organisms, disrupt food chains, and contaminate water sources. The goal is to analyze the heavy metal content, pH, and colour of batik wastewater to make it safe for plant irrigation. The filtration process uses silica sand, activated carbon, and zeolite for mechanical filtration and ion exchange. Ultrafiltration is added to remove fine particles, heavy metals, and organic matter more effectively while resisting fouling. These materials are placed in zipper bags for easy replacement and regeneration. The wastewater passes through a filtration column consisting of two tanks: Tank 1 for fresh wastewater and sedimentation, and Tank 2 for overflow from Tank 1. Tests were conducted for Cr, Cu, Pb, and Zn using AAS, pH with a universal pH meter, and colour through organoleptic analysis. Cr levels initially exceeded quality standards, while Cu, Pb, and Zn were within safe limits. After filtration, reductions of Cr, Cu, Pb, and Zn were 81%, 8%, 22%, and 85%, respectively. The pH decreased from 10–11 to 7–8, and water color improved from murky greenish-brown to clearer. The results demonstrate the potential of ultrafiltration in reducing heavy metals, stabilizing pH, and improving water clarity. Wastewater treated through this process meets safety standards and can be used for plant irrigation.

Abstract

Wastewater Treatment Plant is an important facility designed to process wastewater from various sources, such as households and industries, before it is discharged into the environment. The main purpose of WWTP is to eliminate or reduce contaminants in wastewater to meet the quality standards set by the government. The treatment process involves the screening stage of solid material, sludge sedimentation, and decomposition of biological or chemical contaminants. One of the main challenges in wastewater treatment is sludge carryover to the processing system, which can reduce pollutant parameters such as Biochemical Oxygen Demand, Chemical Oxygen Demand, Total Suspended Solids and ammonia. This study aims to design a sludge filtration system consisting of bar screening, sedimentation, and filtration unit with a combination of silica sand. The design is outlined in the form of a scientific article to contribute to the development of wastewater treatment studies. The bar screen is used to filter rough solids in the early stages, sedimentation is used to separate heavy particles using gravity, and the filtration unit is designed using a single silica sand filter to reduce TSS. With a processing discharge of 6,300 m³/day, the resulting design is expected to improve the operational performance of WWTPs, meet the wastewater quality standards according to PerMen LHK No. 16 of 2016, and produce good quality effluent BOD 13,43 mg/L, COD 40,47 mg/L, TSS 1,9 mg/L and ammonia 0,42 mg/L. The results of this planning provide a sustainable and efficient solution for wastewater treatment.

Abstract

Eyeshadow is used to give the eye dimension to look attractive, so the selection of eyeshadow materials needs to be considered to avoid side effects that can occur on the surface of the eyelids. Eyeshadow can be made from natural ingredients. One of the natural ingredients that can replace talcum chemicals is chicken eggshell powder because chicken eggshell powder contains a source of calcium that can nourish the skin. Rosella flower petal powder extract is also added as a natural colourant for manufacturing this compact eyeshadow powder. In addition to functioning as a colourant, Rosella flower petals contain anthocyanins and flavonoids, which have antioxidant and antibacterial properties. This study aims to determine the innovation process of chicken eggshell waste into Compact Powder Eyeshadow as decorative cosmetics by analyzing the feasibility of eyeshadow through organoleptic tests, pH tests, particle uniformity tests, specific gravity tests, and water content tests. This study's results show that formula III's physical quality with an extract concentration of 50% has good physical quality compared to other concentrations because the resulting colour is light. However, the colour resistance produced is the same as other formulas and does not last long.

Abstract

Cow's milk provides essential human nutrients, including calcium, protein, and minerals. However, it is highly susceptible to bacterial contamination, which leads to rapid spoilage. Pasteurization is the most common method to process cow's milk, effectively reducing microbial levels. However, some heat-resistant bacteria can survive the pasteurization process, limiting its effectiveness in ensuring long-term milk safety. This study investigates the use of chemical engineering technology by combining pasteurization and UV-C radiation methods, either sequentially or simultaneously, to improve the effectiveness of milk sterilization. The use of combined techniques aims to leverage the strengths of both processes, achieving superior microbial reduction and extending milk shelf life. Different operating temperatures and radiation durations were tested to identify optimal processing conditions. The findings revealed that this combined approach achieved a significant bacterial reduction of 99.95%, decreasing the microbial count from an initial 1.9 × 10⁶ cfu/mL to 7.0 × 10² cfu/mL. Moreover, the shelf life of the milk was extended to five months, demonstrating the effectiveness of the hybrid method. The study also monitored the milk's acidity (pH) throughout the process, which remained within optimal conditions of 6.5 to 6.8. This indicates that the combined treatment does not compromise milk quality. Integrating pasteurization with germicidal UV-C radiation offers a promising alternative for milk sterilization, improving microbial control and significantly increasing the shelf life of cow's milk. The results suggest that this dual-method approach could be a valuable advancement in dairy processing, enhancing both safety and efficiency in the production and preservation of milk.

Meskipun BUMDes memiliki peran strategis dalam menggerakkan perekonomian desa, kompleksitas operasional dari berbagai unit usaha (telur bebek, peternakan kambing, dan pengelolaan sampah) memerlukan sistem pelaporan keuangan yang transparan dan akuntabel. Metode Participatory Rural Appraisal (PRA) digunakan untuk memastikan partisipasi aktif pengelola BUMDes. Pelaksanaan kegiatan dibagi menjadi dua tahap: pelatihan akuntansi sederhana dan pendampingan intensif. Pelatihan berfokus pada edukasi pencatatan keuangan yang mudah dipahami, sementara pendampingan membantu pengelola menyusun laporan persediaan, kas masuk, kas keluar, dan aset tetap. Hasilnya menunjukkan peningkatan signifikan dalam pemahaman dan kemampuan pengelola untuk menyusun laporan keuangan yang terstruktur. Hal ini tidak hanya meningkatkan efisiensi operasional dan akuntabilitas, tetapi juga menjadi fondasi untuk pengambilan keputusan yang lebih baik dan peningkatan kepercayaan dari masyarakat dan pemangku kepentingan. Abstract This community service program aims to address the financial management challenges faced by BUMDes Kalongan Jaya Mandiri, which could potentially hinder its business sustainability. Although BUMDes plays a strategic role in driving the village economy, the operational complexity of its various business units (duck egg production, goat farming, and waste management) requires a transparent and accountable financial reporting system. The Participatory Rural Appraisal (PRA) method was used to ensure the active participation of BUMDes managers. The project was divided into two phases: simple accounting training and intensive mentoring. The training focused on educating managers on easy-to-understand financial record-keeping, while the mentoring helped them prepare inventory reports, cash inflow and outflow statements, and fixed asset lists. The results showed a significant improvement in the managers' understanding and ability to create structured financial reports. This not only enhanced operational efficiency and accountability but also served as a foundation for better decision-making and increased trust from the community and other stakeholders.

Abstract

Solvent is one of the important components in chemical processes. The type of solvent that is often used in the paint and coating industry is a hydrocarbon-based solvent which consists of a diverse complex mixture of liquids and contains aliphatic, alicyclic and aromatic (C5-C8) elements. Aromatic hydrocarbons are environmental pollutants that are known to be toxic, carcinogenic and mutagenic, so a hydrocarbon-based solvent with an aromatic content of less than 1% is needed. An appropriate separation method for separating aromatic and nonaromatic components having close boiling points is extractive distillation with a sulfolane entrainer. In this study, a distillation system with a sulfolane entrainer was run using the process simulation software Aspen Plus with the aim of understanding the effect of the amount of sulfolane, feed stage and number of stages on the physical properties of hydrocarbon-based solvents. This simulation is focused on the variation of the ratio of sulfolane: crude feed (7:1, 7.5:1, 8:1, 8.5:1), the variation of the feed stage (10th stage to the 35th stage) and the variation of the number of stages (70, 75, 80). It was found that the number of stages did not affect the density and flash point of the solvent. An increase of number of stage will decrease the solvent flash point and density. Significant decreament also can be found when the sulfolane to crude feed ratio is increased. However, the physical properties of the current dearomatized solvent is close to the properties of commercial product namely SBP 65/70 from one of oil and gas companies.
