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

Fly ash and bottom ash (FABA) in Sawahlunto City are backfilling materials for former mining areas. The FABA dumping is estimated to hurt groundwater. This study aims to analyze the concentration of Pb metal in groundwater and its distribution using response surface methodology. This study is a quantitative experimental field research using Response Surface Methodology (RSM). The research subjects involved were groundwater samples from four different points around the fly ash and bottom ash (FABA) dumping location in Sawahlunto City. The data collection method was carried out by taking groundwater samples three times consecutively with a three-week interval, following the procedures of SNI 6989.58: 2008 and SNI 6989-84: 2019. Data analysis methods included ANOVA and RSM tests in the SAS platform. The research findings showed that the groundwater at the study location did not meet drinking water quality with a Pb concentration of 0.144 mg/L exceeding the quality standard (0.01 mg/L). The accumulation of FABA in former mining areas pollutes groundwater with Pb parameters. The distribution pattern of Pb decreases with increasing distance and increases with increasing time. Therefore, the government needs to re-evaluate the implementation of FABA utilization as a filling material for former mining areas. The implications of this study indicate the need to re-evaluate the practice of FABA disposal in mine pits, as improper waste disposal will negatively impact groundwater quality.

Abstract

Reaktor Upflow Anaerobic Sludge Blanket (UASB) merupakan teknologi pengolahan air limbah dengan metode anaerobik yang telah diakui manfaatnya. Kelebihan reaktor UASB dibandingkan dengan metode anaerobik dan aerobik yang lain adalah pemanfaatan energi yang rendah dan ramah lingkungan, kebutuhan ruang yang minimal, dan biaya operasional serta pemeliharaan yang rendah. Beberapa parameter utama yang mempengaruhi proses pengolahan UASB antara lain parameter suhu, Hydraulic Retention Time (HRT), Organic Loading Rate (OLR), pH, granulasi, dan mixing. Salah satu produksi biogas yang dihasilkan dari pengolahan air limbah dengan reaktor UASB adalah hidrogen. Langkah-langkah posttreatment setelah pengolahan dengan reaktor UASB merupakan hal yang perlu diperhatikan agar kualitas efflluen yang dihasilkan sesuai dengan standar yang berlaku.

Abstract

This study evaluates the efficiency of water usage in the Department of Environmental Engineering at Universitas Andalas (Unand) by analyzing water consumption volume, identifying potential leaks, and comparing the findings with applicable standards for laboratories and offices. A 1.5-inch water meter was installed at the outlet of the rooftop reservoir on the 4th floor to measure water usage volume, and manual attendance devices were used to record the number of water users in the office and laboratory. Leakage testing was performed using the step test method, where water flow was stopped for 16 hours overnight to monitor changes in the water meter readings, with results indicating no leakage. The study found that the highest water consumption was 39.66 L/person/day in the laboratory and 55.06 L/person/day in the office. Water consumption in laboratories was found to be 100-200 L/person/day according to the standard, while water use in offices slightly exceeds the Indonesian National Standard (SNI) 03-7065-2005 of 50 L/person/day. The study recommends implementing water conservation technologies, such as automatic faucets and dual-flush toilet systems, to reduce water consumption and enhance water efficiency.

Abstract

The growth of illegal shrimp ponds in Batang Anai, Padang Pariaman Regency has been very widespread recently. This is because the advantages of shrimp cultivation include fast growth, high survival rate, high shrimp appetite, greater resistance to disease attacks and relatively short rearing time, namely 90-100 days per cycle. As shrimp cultivation develops in this area, environmental pollution problems arise. Of course, this is contrary to Law number 36 of 2009 concerning Health, Article 4 and Article 6 states that everyone has the right to health and everyone has the right to a healthy environment for achieving a level of health. Based on preliminary interviews with the community around the shrimp ponds, it was stated that the existence of illegal shrimp ponds does not take into account the impact on the environment, and even disturbs the community. Meanwhile, there is no action by the district or local government to control or manage the impacts, so various efforts are needed to restore optimal health status for the surrounding community.
