Abstract

Mengingat percepatan ekspansi di berbagai industri, kebutuhan air baku untuk berbagai penggunaan terus meningkat. Di sisi lain, ketersediaan air bersih masih terbatas. Pasokan air bersih juga menjadi masalah di Kawasan Industri x. Wilayah ini memiliki suplai air yang cukup dalam bentuk bosem dan jaringan distribusi yang mendistribusikan air bersih ke gudang dan perusahaan di wilayah tersebut, namun persoalannya adalah bagaimana mengolah dan mendistribusikan air dari sumber air tersebut ke daerah yang belum memiliki jaringan distribusi air bersih yang optimal sehingga pelanggan bisa mendapatkannya. Studi ini menggunakan cara pengumpulan data dari pengembang kawasan industri x. Program Epanet dapat digunakan untuk merancang distribusi air bersih dan sebagai tolok ukur untuk mengevaluasi dan membandingkan kondisi lapangan. Hasil analisis menunjukkan 26 lokasi junction melebihi kriteria kualitas (>100 m), dengan nilai tekanan minimum 49,25 m dan nilai tekanan maksimum 102,72 m. Tujuh puluh enam pipa distribusi air memiliki kecepatan di bawah 0,3 m/s, sedangkan satu pipa memiliki kecepatan di atas syarat mutu, yaitu 3,7 m/s pada jam-jam kritis. Hasil EPANET menunjukkan bahwa sekitar pukul 11.00, 13.00, dan 14.00 terjadi tekanan negatif yang menandakan bahwa pipa kehilangan air atau tekanan sehingga air tidak dapat disalurkan ke pelanggan. Hal ini sesuai dengan kondisi lapangan, dimana pada jam – jam kritis itu terjadi penggunaan air yang tinggi.

Abstract

pH is one of the indicators that determines the quality of wastewater that can affect the wastewater treatment process. Changes in pH in water greatly affect the physical, chemical, and biological processes of organisms living in it. This study was conducted to analyze the pH quality of water in the PT Coronet Crown Wastewater Treatment Plant (IPAL), before and after the addition of ultilox waste, with the addition of coagulant as an indicator that can maintain the pH of the water. Monitoring was carried out for one month after the addition of ultilox waste, namely from October 7 to November 7, 2024. The parameters measured included changes in the pH of wastewater from day to day. The pH quality standard used is in accordance with applicable regulations, namely 6-9. The measurement results showed that the pH of wastewater in the IPAL before the addition of ultilox was 7.2, but after the addition of ultilox, the pH changed to 6.5. The data shows that the pH before, during the addition, and after the addition of ultilox waste still meets the quality standards in the range of 6-9.

Abstract

The management of plant-based organic waste in industrial environments is an important component of waste reduction efforts and the implementation of sustainable environmental management principles. A manufacturing industry in Surabaya manages plant residue waste through an internal composting system that has not fully applied controlled aerobic composting principles. This activity aims to evaluate the semi-aerobic composting system implemented, particularly in terms of process flow, composting duration, and the quality of the resulting compost compared to applicable standards and regulations. The method used was a descriptive qualitative approach with an evaluative framework, conducted through field observations, interviews, and monitoring of process parameters such as temperature and pH. The results indicate that the composting process required a longer duration than the ideal timeframe due to the absence of material shredding and limited aeration, which reduced microbial activity during decomposition. These conditions affected compost quality, resulting in non-uniform maturity and characteristics that did not fully meet compost maturity criteria. This evaluation provides an overview of the existing composting system and serves as a basis for developing improvement recommendations to enhance process efficiency and compost quality in accordance with applicable composting standards.

Abstract

The drinking water depot at PT. Y is crucial for employees to support their work and prevent dehydration and fatigue. However, if health standards are not optimally implemented, it can increase the possibility of contamination, which can impact water quality and employee health. Good drinking water is water that is free from physical, chemical, and microbiological contamination. This study aims to ensure that sanitation and hygiene standards at PT. Y are in good condition. This depot uses raw water from the mountains, transported by tanker trucks and treated through a silica filtration system, activated carbon, micron membranes, and ultraviolet light disinfection. The study used an observation and evaluation approach. Data collection was carried out through observation and interviews. The hygiene and sanitation assessment refers to the Risk-Based Food Hygiene and Sanitation Guidelines issued by the Ministry of Health in 2021. After conducting the analysis, the results showed that the drinking water depot at PT. Y generally complies with most sanitation and hygiene requirements, both for quality standard equipment and for handlers. This is evidenced by a very high inspection score of 96.4, indicating a low risk of non-conformity. However, there were minor deficiencies in the building and raw water aspects, for which there were no purchase receipts. These deficiencies can be used as evaluation points for improvements during future audits.

Abstract

Batik wastewater contains high levels of total suspended solids (TSS) and turbidity, making it difficult to decompose naturally. To prevent environmental pollution, this study investigated a treatment method that combined coagulation in a mixing tank and flocculation using a hydrocyclone. Polyaluminum chloride (PAC) was used as the coagulant. The coagulation process was tested at stirring speeds of 100–140 rpm and coagulant doses of 150–300 mg/L. The results showed that a coagulant dose of 300 mg/L and a stirring speed of 140 rpm achieved the highest removal efficiencies: 95.45% for TSS and 95.24% for turbidity. A two-way analysis of variance (ANOVA) confirmed that the coagulant dose significantly affected removal efficiency (p=0.049), whereas the stirring speed did not have a significant effect (p=0.77). Furthermore, particle size analysis (PSA) and zeta potential tests indicated that the PAC coagulant successfully destabilized the suspension in the wastewater, leading to the formation of large aggregates and accelerating the separation process. Overall, these results indicate that combining a coagulation mixing tank with a hydrocyclone flocculation unit offers an efficient and rapid solution for treating batik wastewater.

Abstract

The electroplating industry generates wastewater containing hazardous heavy metals such as copper (Cu) and nickel (Ni), which can contaminate aquatic and terrestrial environments. Initial tests showed Cu and Ni concentrations of 92.6 mg/L and 76.23 mg/L, respectively—far exceeding the permissible limits. To address this issue, an environmentally friendly treatment technology was employed, using a subsurface-flow constructed wetland planted with Cyperus papyrus. The study used combinations of soil and rice husk biochar media at weight ratios of 1:0, 1:1, 1:2, and 2:1. Aeration pretreatment was conducted for 24 hours before wastewater was introduced into the subsurface flow wetland. The hydraulic retention times were 0, 5, 10, and 15 days. The results indicated that the 2:1 media combination under aerated conditions achieved the highest removal efficiencies—93.02% for Cu and 96.81% for Ni on the 15th day. Plant tissue analysis revealed the highest metal accumulation in the roots, with Cu and Ni contents of 0.315 mg/g and 0.241 mg/g, respectively.

Abstract

Organic waste management has become a significant issue, particularly with the increasing amount of waste generated from agricultural, livestock, and household activities. One of the most widely applied technologies is the biodigester, which utilizes anaerobic digestion to decompose organic matter into compost and biogas. However, conventional biodigesters often face limitations in methane production efficiency, which is strongly influenced by substrate quality and microbial diversity. Rumen substrate from cows contains cellulolytic and methanogenic microbial communities that play a key role in accelerating the degradation of complex organic matter and enhancing methane production. This study aimed to investigate the impact of varying rumen substrate amounts on the performance of biodigesters. Three treatments were applied: no rumen addition, addition of 1 Kg, and addition of 2 Kg. Parameters observed included C/N ratio, pH stability, and methane gas percentage during a 35-day anaerobic fermentation period. The results showed that the biodigester with 1 Kg of rumen achieved a C/N ratio of 21.23, which falls within the optimal range of 20–30. Meanwhile, the biodigester with 2 Kg of rumen produced the highest methane percentage, reaching 0.0185% v/v on day 14, although production gradually declined thereafter. Overall, the addition of rumen was proven to improve the C/N ratio, stabilize pH, and enrich microbial communities, thereby enhancing methane production efficiency. These findings suggest that rumen substrate can be considered a potential co-substrate to enhance biodigester performance and facilitate sustainable organic waste management.
