Abstract

The waste processing performance at the Integrated Waste Processing Center of Andalas University has experienced a decline; therefore, an evaluation and development of the waste processing system are needed. This research aims to analyze planning data for the waste processing system, including waste generation analysis, composition, recycling potential, and waste characteristics. Waste samples were taken from 48 campus facilities representing office activities, academic activities, student activities, and other activities. Waste generation, composition, and recycling potential analyses were conducted in the field using gravimetric methods, while characteristic analyses were performed in the laboratory.From the research results, planning data for the campus waste generation unit was obtained at 0.0592 kg/person/hour or 0.00163 kg/m²/hour, and in volume units, it was 0.5245 liters/person/hour or 0.02945 liters/m²/hour. The waste composition consisted of 49.61% easily decomposable waste, 38.22% recyclable waste, 1% hazardous waste (B3), and 16.21% residual waste. The potentially recyclable waste includes food waste, yard/wood waste, plastic, paper, glass, and metal, with an average potential of 89%. Waste characteristics include a specific gravity of 0.058, moisture content of 22.18%, volatile matter content of 59.95%, fixed carbon content of 12.09%, ash content of 5.79%, C/N ratio of 30.28, biodegradability of 54.06%, and a fly population of 2 flies/m².Campus waste has the potential to be processed through composting, Black Soldier Fly (BSF) bioconver sionand biodrying for easily decomposable waste, and it can be sold to the informal sector for recycling.

Abstract

The increasing demand for paper products over time has led to a corresponding increase in the amount of paper waste generated. Andalas University Campus endorses the recycling concept through the establishment of an Integrated Waste Management Center (PPST), which encompasses the Andalas Enviro Waste Bank (BSEA). This center is designed to oversee the management of dry waste that is suitable for sale, with the proceeds from such sales being directed to third parties. This study examines the optimization of paper waste utilization at the Andalas University Campus in Limau Manis, Padang. The study referenced data on the generation, composition, and recycling potential of paper waste from the Unand campus, as well as existing conditions of paper waste management at each source, obtained through the distribution of questionnaires and interviews. The results of the calculations demonstrate that the quantity of paper waste suitable for sale on the Unand campus is 779.82 kg/day. The BSEA is responsible for the collection of this waste through the waste bank system. The study was conducted by creating three scenarios for the management of paper waste: (I) direct sales of paper waste without processing; (II) processing of cardboard waste into egg containers and other types of paper waste into recycled paper; and (III) processing of HVS paper waste and selling other paper waste. The results of the assessment, conducted using incremental IRR analysis and scoring methods, indicated that scenario III was the optimal management scenario for optimizing the utilization of marketable paper waste at the Andalas University Limau Manis Campus from a technical and financial perspective.

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.
