Abstract

PT X is a chemical manufacturing company specializing in the production of phosphoric acid and sulfuric acid. In addition to waste generated from production processes, PT X also produces domestic wastewater originating from supporting activities such as employee barracks, offices, and laundry facilities. This domestic wastewater contains parameters that can potentially pollute the environment, such as BOD, COD, TSS, ammonia, and Total Coliform, some of which exceed the quality standards set by the Minister of Environment Regulation No. 68 of 2016. This study aims to design an effective Domestic Wastewater Treatment Plant (DWTP) system to process the domestic wastewater of PT X. The proposed DWTP system consists of a collection tank, Anaerobic Baffled Reactor (ABR), Aerobic Biofilter, and disinfection unit. Each unit is designed to reduce pollutant parameters to meet quality standards. Based on the calculations, this system can handle a wastewater flow rate of 21.91 m³/day with high treatment efficiency for critical parameters. The study results indicate that the proposed DWTP design can reduce environmental pollution, improve wastewater treatment operational efficiency, and comply with applicable regulations. Implementing this system is highly recommended to ensure environmental sustainability and the continued operations of PT X.

Abstract

ABSTRAK Kegiatan Fasilitas Pendidikan X menghasilkan sampah setiap harinya. Pada Fasilitas Pendidikan X terdapat aktivitas murid, guru, dan karyawan dengan total sebanyak 549 orang. Aktivitas tersebut menghasilkan timbulan sampah yang relatif besar pula. Tujuan perencanaan sistem pengomposan dengan metode takakura pada Fasilitas Pendidikan X untuk meminimalisir total timbulan sampah yang dihasilkan sebesar 0,411 m3/hari sebelum diangkut menuju Tempat Pemrosesan Akhir (TPA) dengan mengolah sampah organik sebesar 0,23 m3/hari sehingga sisa timbulan sampah menjadi sebesar 0,181 m3/hari. Metode takakura adalah teknik pengomposan sederhana yang memiliki keunggulan karena dapat di produksi pada area yang terbatas dan melalui proses fermentasi sehingga tidak menimbulkan bau. Berdasarkan perencanaan, didapatkan hasil kompos sebesar 2,31 m3/bulan atau sebesar 2.310 kg/bulan yang dapat dimanfaatkan. Pada dasarnya, kompos memiliki berbagai manfaat utamanya dapat mengurangi timbulan sampah organik pada Fasilitas Pendidikan X dengan memanfaatkan kembali sebagai pupuk organik yang selanjutnya dapat diaplikasikan pada tanah, dijadikan sebagai pupuk tanaman pada ruang terbuka hijau yang tersedia di Fasilitas Pendidikan X, serta dapat dijual kembali apabila hasil dari komposting yang didapatkan melebihi kebutuhan kompos yang dibutuhkan oleh Fasilitas Pendidikan X. ABSTRACT The educational facility X generates waste every day. In Facility X, there are activities involving students, teachers, and staff, totaling 549 people. These activities produce a relatively large amount of waste. The goal of planning a composting system using the Takakura method at Facility X is to minimize the total waste generation, which is currently at 0.411 m3/day, before it is transported to the Final Processing Site (TPA). This will be achieved by processing organic waste amounting to 0.23 m3/day, resulting in a remaining waste generation of 0.181 m3/day. The Takakura method is a simple composting technique that has the advantage of being producible in limited spaces and utilizes a fermentation process, thus preventing odors. According to the planning, a compost yield of 2.31 m3/month or 2,310 kg/month is obtained, which can be utilized. Essentially, compost has various primary benefits, including reducing the generation of organic waste at Facility X by reusing it as organic fertilizer that can be subsequently applied to the soil, used as plant fertilizer in the green open spaces available at Facility X, and can also be sold if the compost produced exceeds the compost needs of Facility X.

Abstract

Soil contamination by heavy metals, particularly lead (Pb), is a serious environmental issue in Indonesia, as it affects human health, ecosystems, and land productivity. Pb can accumulate in plants and enter the food chain, increasing public health risks. Therefore, an effective, low-cost, and field-applicable remediation method is required. One potential approach is aeration, which involves oxygen addition to improve soil porosity and enhance heavy metal stabilization. However, the effectiveness of aeration is strongly influenced by soil physical properties; hence, this study focuses on the effect of soil–sand composition on Pb stabilization in Inceptisol soil. The research was conducted using a laboratory-scale batch reactor with Inceptisol soil contaminated by Pb(NO₃)₂ (300 mg/kg). Treatments included three soil–sand ratios (100:0, 70:30, and 60:40) and three aeration durations (non-aerated, 12 hours, and 24 hours). Parameters analyzed were residual Pb²⁺ concentration and soil physical characteristics, with data processed using two-way ANOVA. Results showed that sand addition improved aeration effectiveness, achieving the highest Pb removal (94,6%; final Pb 17,1 mg/kg) at 60:40 composition with 24-hour aeration. In contrast, pure soil without aeration showed the lowest effectiveness (76,1%). Statistical tests confirmed that media composition, aeration duration, and their interaction significantly affected Pb stabilization (p < 0,05). This study demonstrates that combining aeration with sand addition offers a simple and practical method for remediating Pb-contaminated Inceptisol soil.

Abstract

This study examines the effect of soil pH variation on the effectiveness of the aeration method in stabilizing the heavy metal lead (Pb2+). Lead contamination from industrial waste and fossil fuels is a serious environmental problem as it is carcinogenic and can pollute ecosystems, including plants, posing a health risk to humans. Soil remediation is needed to address this issue, and soil aeration is one promising method. However, the effectiveness of aeration is highly influenced by soil environmental conditions, particularly pH, as low pH makes heavy metals easily soluble and mobile. This quantitative experimental study used 3 reactors with variations in pH treatment (acidic pH 4, neutral pH 6.5, and alkaline pH 10) and aeration duration (6 hours/day). Samples were analyzed using Atomic Absorption Spectrophotometry (AAS) to measure the remaining lead concentration, and the stabilization efficiency was calculated from the difference in concentration before and after treatment. The results showed that the alkaline pH treatment (pH 10) consistently provided the highest lead reduction efficiency, reaching 78.7% at a 24-hour aeration duration. Increasing the pH caused the Pb2+ ions to precipitate into insoluble and less toxic compounds. Statistical analysis using ANOVA confirmed that pH and aeration duration had a significant effect on the efficiency of lead (Pb2+) reduction.

Abstract

The tofu industry produces wastewater with high turbidity, requiring treatment before being discharged into the environment. This study aims to utilize bittern, a byproduct of salt pond production, as an environmentally friendly alternative coagulant to reduce turbidity in tofu wastewater. Bittern was activated using three types of strong bases Ca(OH)₂, KOH, and NaOH with dosage variations of 40,50,60 mL and concentrations of 4%,6%,8%. The results showed that all activators enhanced the coagulation performance of bittern, with varying effectiveness under each treatment. NaOH provided the best result at a dosage of 50 mL and a concentration of 4%, achieving a turbidity removal efficiency of 95%. KOH reached optimal performance at 50 mL and 6%, with a turbidity removal efficiency of 93%, while Ca(OH)₂ achieved 85% efficiency at 50 mL and 6%. Overall, this study demonstrates that NaOH-activated bittern is an effective alternative coagulant with potential for sustainable application in tofu wastewater treatment.
