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

This study aims to calculate the quantity of used wudhu wastewater at the Nurul Ilmi Mosque, Universitas Andalas, test the effectiveness of filtration in removing TSS and COD, and evaluate its potential use as non-potable water. Quantity measurements were carried out on Monday, Friday, and Sunday with triplicate tests. Filtration used a continuous PVC reactor (capacity 2.54 L) with an influent discharge of 2 gpm and 4 gpm. The filtration media consisted of activated carbon, zeolite sand, and silica sand. The results showed that the highest volume of used ablution water was on Friday at 35.865 ± 9.67 L/sec. TSS and COD removal at a discharge of 2 gpm and 4 gpm were 74.03% ± 2.98 and 76.19% ± 3.37, and 70.01% ± 2.98 and 70.01% ± 0.00, respectively. The 2 gpm discharge showed the best removal results, although the COD value did not meet the Quality Standards of PP No. 22 of 2021 (class 2). The t-test showed that the variation in discharge did not have a significant effect on the removal of TSS and COD (p>0.05). With its potential for utilization, it is recommended to extend the residence time at a discharge of 2 gpm so that COD meets the quality standards, so that used ablution water can be used as non-potable water.

Abstract

This study analyzes the potential to reuse AC condensate water in Andalas University. The research was conducted in the Rectorate Building, the Civil Engineering Department, and the Environmental Engineering Department. AC condensate water sampling was conducted in 8 locations from the Rectorate, Civil Engineering, and Environmental Engineering office buildings. The parameters analyzed were pH, DO, Turbidity, COD, Metals, E.coli, and Total Coliform. Water quality was compared with the Minister of Health Regulation Number 2 of 2023, World Health Organization (WHO) for Drinking Water Quality Standards and Government Regulation Number 22 of 2021 concerning implementing Environmental Protection and Management. The results of water quality testing show that in addition to the parameters of pH, DO, Turbidity, COD, and Metals that have met the quality standards, the levels of iron (Fe), COD, and Total Coliform exceed the quality standards of the Minister of Health Regulation Number 2 of 2023. Used AC water is not recommended for consumption as drinking water. However, condensate AC water can be used for several activities, such as watering plants, cleaning floors and specific areas, and flushing toilets. The AC condensate water characterization results show that iron (Fe), COD, and Total Coliform parameters exceed the quality standards for drinking water requirements. AC condensate water is not recommended for consumption as drinking water without prior treatment. Used AC water can be utilized for several activities, such as watering plants, cleaning the floor, and cleaning the toilet. Keyword: condensate water; office building; potential; water source

Abstract

Pengolahan sampah makanan belum dilakukan di Pusat Pengolahan Sampah Terpadu (PPST) Kampus Universitas Andalas Limau Manis. Untuk itu dilakukan kajian terhadap pengolahan sampah makanan menggunakan Larva BSF dari aspek teknis, ekonomi dan lingkungan. Kajian aspek teknis dilakukan dengan menganalisis timbulan, komposisi, karakteristik sampah makanan yang berasal dari kantin dan Instalasi Gizi Rumah Sakit Universitas Andalas serta menganalisis kebutuhan lahan dan fasilitas. Kajian aspek ekonomi dilakukan dengan menghitung biaya investasi dan operasional, biaya pendapatan dari penjualan produk dan menganalisis kelayakan investasi. Kajian aspek lingkungan dilakukan dengan penilaian dampak lingkungan yang dilakukan responden yang terdiri dari tenaga peneliti dan praktisi dalam pengolahan sampah makanan dengan Larva BSF. Dari hasil kajian aspek teknis, ekonomi dan lingkungan diperoleh pengolahan sampah makanan menggunakan Larva BSF layak diterapkan di PPST Universitas Andalas dengan kapasitas pengolahan sebesar 112 kg/h dan kebutuhan lahan 9 m2. Biaya investasi yang dibutuhkan sebesar Rp13.117.000 dengan biaya operasional Rp38.006.400. Pendapatan dari penjualan produk diperkirakan sebesar Rp62.186.880. Hasil kelayakan investasi diperoleh nilai NPV Rp88.739.978, BCR 1,512, IRR 183%, dan PP 1 tahun 6 bulan.  Dari kuisioner diperoleh penilaian untuk dampak positif lebih besar dibandingkan penilaian untuk dampak negatif. Untuk itu direkomendasikan adanya kegiatan pemilahan sampah makanan di sumber, penyediaan parasarana dan sarana, peningkatan kadar air sampah makanan serta kerjasama dalam pemasaran produk yang dihasilkan.

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

Perguruan tinggi sebagai pusat aktivitas akademik dengan populasi padat penghuni menghasilkan volume air limbah domestik yang signifikan. Limbah cair dari kantin, laboratorium, asrama, dan fasilitas kampus lainnya berpotensi mencemari lingkungan jika tidak dikelola secara optimal.  Penelitian ini merancang sistem pengolahan air limbah domestik di Kampus X Padang menggunakan teknologi upflow filter septic tank. Perancangan sistem dilakukan mengacu kepada SNI 2398:2017. Sistem yang dirancang mampu mengolah debit total air limbah sebesar 26,45 m3/hari yang terdiri dari 70% greywater dan 30% blackwater. Unit pengolahan utama meliputi grease trap berkapasitas 0,0162 m³ dengan efisiensi penyisihan minyak dan lemak mencapai 95%, tangki septik berukuran 23,637 m³ dengan waktu tinggal 3 hari, serta upflow filter seluas 8,82 m².  Sistem ini mampu menyisihkan parameter pencemar mencapai: BOD 55,8%, COD 58,6%, TSS 87,8%, amonia 75,1%, dan total coliform hingga 100%. Selanjutnya, unit pengolahan disinfeksi dengan kaporit 65% (0,326 kg/hari), dapat menghilangkan total coliform hingga nol. Implementasi sistem ini diharapkan dapat menjadi solusi berkelanjutan untuk pengelolaan air limbah di perguruan tinggi.
