Abstract

The Effluent Treatment Plant (ETP) at PT. Wilmar Nabati Indonesia (PT. WINA) processes wastewater from crude oil (CPO) production activities, as well as serving as a domestic office, workshop, security, quality control, and Niagara equipment washing facility. ETP PT. WINA has a processing capacity of 382 m3 per day. The processing unit at ETP PT. Wilmar Nabati Indonesia is made up of a carrier channel, fat trap, Niagara, ceramic reservoir, equalization tank, chemical reactor alum, cavitation air floatation (CAF) machine, accident tank, filter press, sequencing batch reactor (SBR), reservoir tank, sand filter, oil removal, and carbon filter. The objectives of this research are to evaluate the operation and maintenance of ETP PT. WINA in accordance with the Minister of Environment of the Republic of Indonesia's regulation No. 5 of 2014, as well as to investigate the potential use of sludge from ETP PT. WINA processing that is safe to use and does not have a negative impact on the environment or human health. Operations and maintenance at PT. WINA are addressed by SOP-WINA-ETP-13-001 to SOP-WINA-ETP-010. The quality of wastewater treatment at PT. WINA's ETP has met the quality standards established by the Minister of Environment's Regulation No. 5 of 2014 Attachment XXI concerning Wastewater Quality Standards for the Cooking Oil Industry, and the effluent of PT. WINA's ETP is suitable for discharge into water bodies, namely the sea. Although the ETP effluent has met the quality standards and is suitable for discharge into water bodies, the sludge produced from PT.

Abstract

Universitas Andalas Water Treatment Plant (WTP Unand) is a water treatment plant that serves the drinking water needs of Universitas Andalas with a 90 L/second capacity. WTP Unand has been operating for decades so it is necessary to evaluate the performance and operation of the drinking water treatment system to ensure the quantity and quality of the treated water. This study aims to measure the performance of the Unand WTP unit, analyze the quality of production water produced based on Permenkes No.2/2023 standards for drinking water quality parameters, and analyze the design of the Unand WTP at development discharge. The future flow rate is determined based on the Master Plan of Universitas Andalas in 2030. Based on the analysis of current water demand (year 2023), the flow rate distributed is insufficient. Of the existing water treatment units in WTP Unand, only the Slow Sand Filter (SSF) unit meets the design criteria of the Indonesian National Standard (SNI) 3981: 2008, while the WTP package unit and the Rapid Sand Filter (SPC) unit do not meet the design criteria according to SNI 6774: 2008 at existing and future flow rates. The water quality analysis of WTP Unand found that Total Dissolved Solid (TDS), turbidity, and Total Coliform parameters did not meet the quality standards. The omission of coagulation and disinfection is one of the reasons why some water quality parameters are not compliant. Evaluation of the design criteria of the WTP unit at an increased discharge of 32 L/sec was not fulfilled, so further resizing and redesign of the treatment unit were required.Keywords: Drinking Water Quality, Evaluation, Performance, Water Treatment Plant (WTP) ABSTRAKInstalasi Pengolahan Air Universitas Andalas (IPA Unand) merupakan instalasi pengolahan air yang melayani kebutuhan air bersih Universitas Andalas dengan kapasitas 90 L/detik. IPA Unand sudah beroperasi beberapa dekade sehingga perlu dilakukannya evaluasi kinerja serta operasional sistem pengolahan air minum untuk menjamin kuantitas dan kualitas air yang diolah. Penelitian ini bertujuan mengukur kinerja unit IPA Unand, analisis kualitas air produksi yang dihasilkan berdasarkan standar Permenkes No.2/2023 untuk parameter kualitas air minum dan analisis desain IPA Unand pada debit pengembangan. Debit pengembangan ditentukan berdasarkan Master Plan Universitas Andalas di tahun 2030. Berdasarkan analisis kebutuhan air Universitas Andalas eksisting, debit aliran air yang didistribusikan masih tidak mencukupi kebutuhan. Dari unit-unit pengolahan air yang ada di IPA Unand, hanya unit Saringan Pasir Lambat (SPL) yang memenuhi kriteria desain SNI 3981:2008, sementara pada unit paket IPA dan pada unit Saringan Pasir Cepat (SPC) tidak memenuhi kriteria disain menurut SNI 6774:2008 pada debit eksisting maupun pengembangan. Hasil analisis kualitas air pengolahan IPA Unand ditemukan parameter Total Dissolved Solid (TDS), kekeruhan, dan Total Coliform tidak memenuhi baku mutu. Tidak dilakukannya koagulasi dan desinfeksi merupakan salah satu alasan mengapa beberapa parameter kualitas air tidak memenuhi syarat. Evaluasi kriteria desain unit IPA pada peningkatan debit sebesar 32 L/detik tidak terpenuhi, sehingga diperlukan perubahan dimensi dan desain ulang unit pengolahan lebih lanjut.Kata kunci: Evaluasi, Kinerja, Kualitas Air Minum, Instalasi Pengolahan Air (IPA)

Abstract

This study aims to analyze wastewater characteristics at Universitas Andalas Campus Limau Manis Padang encompassing physical, chemical, and biological attributes, while comparing them to established quality standards and estimating mass loading. Wastewater samples were collected from various sources, including domestic and specific wastewater. Sampling locations and times were chosen based on peak activity. Physical analysis revealed temperature ranging from 27.32 to 31.5°C and TSS concentrations from 130.00 to 580.00 mg/L. Chemical parameters displayed significant variation, with pH values between 2.27 and 9.70, BOD5 concentrations spanning 108.46 to 506.59 mg/L, COD levels from 162.70 to 1,428.00 mg/L, and oil and grease content from 0.20 to 84.31 mg/L. N-total ranged from 47.07 to 309.16 mg/L, sulfate from 72.70 to 1,480.00 mg/L, and phosphate from 1.14 to 98.15 mg/L. Biological attributes showed total coliform counts exceeding 10,000 colonies per 1,000 mL, all surpassing quality standards. Notably, the BOD5/COD ratio indicated low biodegradable quality (values <0.5) for certain wastewater sources. Greywater emerged as the primary pollutant, with substantial mass loadings. Eventually, this study underscores the vital need for wastewater treatment before environmental discharge.Keywords: Characteristics, Domestic Wastewater, Campus, Quality Standards, Hazardous Wastewate

Abstract

University students are key agents in promoting environmental sustainability, making it essential to assess their level of knowledge, attitudes, and actions regarding environmental awareness. This study aims to evaluate environmental awareness among university students through a structured questionnaire survey. The instrument was distributed to 71 students across different academic levels at a university in West Sumatra Province. The results indicate that while most students possess a basic understanding of environmental issues, their ability to analyze, synthesize, and evaluate such issues remains limited. In terms of attitudes, students generally demonstrate positive dispositions, although further development is needed to foster active participation and social responsibility. Regarding environmentally conscious actions, students have not yet consistently adopted sustainable behaviors, particularly at the level of habitual and innovative practices. Key behaviors that require improvement include waste separation, refusal to use plastic bags, the use of reusable food containers, and recycling practices. These findings highlight the need for more practical and reflective environmental education at the higher education level. Keyword: university students, knowledge, attitude, action, environment

Abstract

This research aims to analyze the potential of utilizing rainwater at the Rectorate Building of Universitas Andalas by examining both its quantity and quality, and by proposing an appropriate rainwater harvesting system (RWHS) design. The quantitative assessment employed 20 years (2003–2022) of maximum daily rainfall data collected from the Batu Busuak Station as the primary reference, supported by three additional stations. Based on a planned roof catchment area of 53.25 m², the calculated runoff discharge is 0.00013 m³/s, indicating that rainwater has considerable potential to serve as an alternative water source. The quality of rainwater shows that parameters such as temperature, dissolved oxygen (DO), chemical oxygen demand (COD), biochemical oxygen demand (BOD), turbidity, iron (Fe), and manganese (Mn) comply with the water quality standards set by the Regulation of the Minister of Health No. 2 of 2023 and Government Regulation No. 22 of 2021. However, the rainwater exhibits an acidic pH (4.14 ± 0.53) and elevated Escherichia coli levels (34.03 ± 41.86 MPN/100 mL), which exceed permissible limits and require treatment prior to use. The selection of suitable treatment technologies was conducted using the Simple Additive Weighting (SAW) method. The analysis showed that sand–calcite filtration system combined with chlorination as the most effective option, achieving a score of 95.90. This system is recommended for non-potable applications, specifically for toilet flushing, with an estimated water demand of 4.93 m³ and a ground tank capacity of 5 m³. The total estimated cost of the proposed RWHS is approximately IDR 26,258,000. Keyword: rainwater, rainwater quality, Log Pearson Type III, Simple Additive Weighting, Rainwater Harvesting System
