Abstract

This study examined the removal of nitrate from wastewater using column adsorption method with variations in the ratio of biochar and polyurethane foam, as well as variations in flow rate. The results showed that the highest adsorption capacity was obtained at a flow rate of 30 mL/min compared to other flow rate variations. At that flow rate, the nitrate sorption capacity reached 4.10 mg/g with biochar, 0.20 mg/g using biochar : polyurethane foam (1 : 1) media, and 13.12 mg/g using biochar : polyurethane foam (2 : 1) media. The biochar : polyurethane foam (2 : 1) media showed the highest nitrate adsorption capacity, which was caused by an increase in the contact time of the flow in the media due to more polyurethane foam volume. This study concludes that sufficient contact time between the contaminant and the adsorption media in the column is a key factor for nitrate removal optimization in addition to the adsorbent material used.Keywords: Adsorption, Biochar, Polyurethane foam, Nitrate ABSTRAKPenelitian ini mengkaji penyisihan nitrat dari limbah cair menggunakan metode adsorpsi kolom dengan variasi rasio biochar dan busa poliuretan, serta variasi laju alir. Hasil penelitian menunjukkan kapasitas adsorpsi tertinggi diperoleh pada laju alir 30 mL/menit dibandingkan variasi laju alir lainnya. Pada laju alir tersebut, kapasitas sadorpsi nitrat mencapai 4,10 mg/g dengan biochar, 0,20 mg/g menggunakan media biochar : busa poliuretan (1 : 1), dan 13,12 mg/g menggunakan media biochar : busa poliuretan (2 : 1). Media biochar : busa poliuretan (2 : 1) menunjukkan kapasitas adsorpsi nitrat paling tinggi, yang disebabkan oleh peningkatan waktu kontak aliran dalam media akibat kandungan busa poliuretan yang lebih banyak. Penelitian ini menyimpulkan bahwa waktu kontak yang cukup antara kontaminan dan media adsorpsi dalam kolom merupakan faktor kunci untuk optimasi penyisihan nitrat selain material adsorben yang dipakai.Kata kunci: Adsorpsi, Biochar, Busa poliuretan, Nitrat

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

Water is a very important component for all life on earth. Iron is a heavy metal, and levels can be dangerous if they exceed threshold levels. Preliminary tests show that Fe in well water is 1.66 mg/l. This study aims to analyze the effectiveness of removal of iron (Fe) contained in well water using a combination of zeolite – pumice adsorbent media. One method that can be used to set aside iron (Fe) parameters in well water is the adsorption method. The adsorption process was carried out continuously with downflow for 150 minutes with sampling every 30 minutes for analysis with a Hach DR 1900 series spectrophotometer. Based on the results of the FTIR characterization analysis of zeolite adsorbents it was indicated that the functional groups were O–H hydroxy stretching vibrations, O-H bending vibrations, stretching vibrations. asymmetric Si-O-Si or Al-O-Al and symmetrical stretching vibration Si-O-Si or Al-O-Al. While the pumice adsorbent before and after being activated, there was a shift in wave numbers with the same functional groups, namely the O-H, C=O, Si-O and Al/Si-O bond groups. Of the five treatments, it is known that treatment V (ZEO30-AP70) is the most effective treatment in reducing Fe levels in well water with a removal efficiency of 98% in the 90th minute and the suitable isotherm model is the Langmuir isotherm with a maximum adsorption capacity of 0, 000739809 mg/g.

Abstract

Final Disposal Sites (landfills) serve as the endpoint in the municipal solid waste management system, functioning as the final destination for our daily waste. Currently, Indonesia is experiencing a waste crisis due to the continuously increasing volume of waste generation, which leads to the rapid overfilling of landfill sites. One of the potential solutions for utilizing landfill waste is the production of Refuse-Derived Fuel (RDF), an alternative fuel derived from solid waste. However, waste that has been buried in landfills generally contains high moisture content, rendering it unsuitable for immediate RDF application. The calorific value of RDF depends greatly on its moisture content, with higher moisture levels resulting in lower energy output. Therefore, a pre-treatment process in the form of drying is necessary to reduce moisture content and optimize the fuel quality of RDF. This study applies the Solar Greenhouse Biodrying (SGB) method as a waste drying technology that combines heat from solar radiation with biological heat generated during aerobic degradation. This method was selected due to its suitability to Indonesia’s tropical climate and its potential for large-scale application without requiring high external energy input. The waste material used in this study was obtained from landfill waste excavated at a depth of 3 meters, with an estimated age of approximately 9 years. In this study, a mixture of fresh waste and excavated landfill waste was dried using various composition ratios: 1:0 (control), 1:1, 1:2, 1:3, and 1:4. The results show that the SGB method effectively reduced moisture content by 27–62.2% and increased the calorific value to a range of 7.5–14 MJ/kg. The waste composition ratio significantly influenced moisture reduction, with the most optimal result found at a 1:2 ratio, which provided the best balance between drying efficiency and energy enhancement. These findings indicate that the SGB method is an effective alternative for waste drying prior to further utilization as RDF.

Abstract

Analisis dan pemetaan tingkat kebisingan dilakukan pada Kampus Universitas Sumatera Utara (USU). Pengukuran kebisingan dilakukan pada 19 titik yang mewakili hari kerja dan hari libur dengan menggunakan Sound Level Meter (SLM). Penelitian ini bertujuan untuk menganalisis tingkat kebisingan, pemetaan pola sebaran tingkat kebisingan serta menentukan upaya pengendalian yang dapat dilakukan. Hasil pengukuran menunjukkan bahwa nilai kebisingan pada Kampus USU menunjukkan nilai 30,98 – 76,54 dB(A). Jika dibandingkan dengan baku mutu, tingkat kebisingan Kampus USU telah melebihi batas kebisingan kawasan institusi pendidikan, yaitu 58 dB(A). Peta pola sebaran tingkat kebisingan menunjukkan bahwa kebisingan di Kampus USU didominasi oleh zona merah. Zona merah menunjukkan bahwa intensitas kebisingan Kampus USU cukup tinggi. Upaya pengendalian kebisingan yang direncanakan adalah pemasangan media penghantar berupa pemasangan pagar batako dan penanaman tanaman yang dapat mereduksi kebisingan hingga 25 dB(A).
