Konsep pengelolaan sampah telah lama berubah dari pemusnahan atau pembuangan menjadi pemanfaatan. Namun konsep ini belum diikuti dengan langkah nyata oleh pemerintah. Kepedulian terhadap kelestarian lingkungan telah mendorong beberapa kelompok masyarakat, lembaga atau institusi untuk bergerak aktif dalam pemanfaatan sampah. Universitas Andalas sebagai lembaga pendidikan tinggi terkemuka di Pulau Sumatera sudah saatnya mengambil peran aktif dalam melakukan pengelolaan sampah yang berwawasan lingkungan. Timbulan sampah yang cukup besar yaitu 28 m3/hari pada tahun 2012, yang diproyeksikan akan menjadi 34 m3/hari atau 9 ton/hari pada tahun 2017, menawarkan potensi cukup besar untuk dimanfaatkan. Pada tahun proyeksi 2017 dari total timbulan sampah, 26,6 % (2,4 ton/h) adalah sampah makanan, 9,8 % (0,9 ton/h) adalah sampah penyapuan taman/jalan, 30,0 % (2,7 ton/h) adalah sampah plastik, 25,3 % (2,3 ton/h) adalah sampah kertas, 1,5 % (0,1 ton/h) adalah sampah kaleng, logam dan besi dan 6,9 % (0,6 ton/h) adalah sampah lain-lain (tekstil, karet, kayu, kaca dll). Dari total sampah makanan dan penyapuan halaman/jalan, 33,7 % berpotensi untuk menghasilkan kompos sekitar 1,2 ton/hari, 2,1 % (0,2 ton/h) dapat dimanfaatkan untuk proses biogas dan sisanya 0,5 % (0,05 ton/h) ditimbun di TPA. Sampah plastik dan kertas sebesar 55,3 % dapat dimanfaatkan kembali atau dijual ke PT. Semen Padang sebagai tambahan bahan bakar unit kiln. Dari 1,5 % sampah kaleng, logam dan besi, 1,3 % dapat dimanfaatkan kembali atau dijual ke pihak ketiga sedangkan sisanya yang hanya sebesar 0,02 ton/h dibuang ke TPA Air Dingin. Selanjutnya, sisa timbulan sampah sebesar 6,9 % yang berupa sampah tekstil, karet, kayu, kaca dan lain-lain dapat dimanfaatkan sebagai bahan bakar alternatif pada kiln PT. Semen Padang. Jika konsep ini dapat dilaksanakan, maka Universitas Andalas dianggap mampu melakukan pemanfaatan sampah hingga 99,3 %. Kata kunci: Pemanfaatan sampah, kelestarian lingkungan, pengelolaan sampah yang berwawasan lingkunganABSTRACTManagement of solid waste has been changed from dumping to utilization. However, this concept is not fully applied yet by the government. Environmental sustainability awareness has been stimulating some community groups and institutions to actively involve in waste utilization. Andalas University as a leading higher education institution in Sumatera Island must give active contributions in solid waste management for environmental sustainability. Solid waste generation of 28 m3/day, which is projected to be 34 m3/day or 9 ton/day in 2017, offers huge enough potency for utilization. From the total solid waste generation in 2017, 26.6 % (2.4 ton/day) is food waste, 9.8 % (0.9 ton/day) is garden/road waste, 30.0 % (2.7 ton/day) is plastic waste, 25.3 % (2.3 ton/day) is paper waste, 1.5 % (0.1 ton/day) can, metal and iron waste and 6.9 % (0.6 ton/day) is micellaneous waste (textile, rubber, wood, glass etc). 33.7 % of food waste and garden/road waste may be recycled to compost around 1.2 ton/day, 2.1 % (0.2 ton/day) may be utilized for biogas and the rest 0.5 % (0.05 ton/day) is sent to TPA Air Dingin. Plastic waste and paper wich is 55.5 %, may be used for additional fuel for kiln unit of PT. Semen Padang. From 1.5 % can, metal and iron waste, 1.3 % may be reused or sold to third party while the reset (only 0.02 ton/day) must be disposed to TPA Air Dingin. Furthermore, the rest of waste generation account for 6.9 % composed of textile, rubber, kayu, kaca dll may be used as alternative fuel for kiln PT.Semen Padang. If this concept is practiced, then the Andalas University is considered capable of utilizing their waste up to 99.3 %.Keyword: Utilization solid waste, environmental sustainability, management of solid waste

Purpose The purpose of this study is to describe the efforts undertaken to convert the large university campus of Jordan University of Science and Technology (JUST) into a green, resource-efficient and low-carbon campus by following an action-oriented strategy. Sustainability features of the campus were discussed and benchmarked. Challenges were identified and remedial actions were proposed. Design/methodology/approach Taking 2015 as the baseline year, data on energy, water consumption and solid waste generation for the university campus were collected. Energy consumption for cooling, heating and transportation, besides electric power consumption, were reported, and the associated carbon dioxide (CO2) emissions were estimated. By calculating the full time equivalent of students and employees, carbon emission and water consumption per capita were calculated. A comparison with other universities worldwide was conducted. Findings Although located in a semiarid region with scarce water resources, JUST has set an example by greening its campus through an action-oriented approach. It was found that the per capita carbon emission for JUST campus was 1.33 ton of CO2 equivalent, which is less than the emissions from campuses of other universities worldwide. As for water, this study revealed that the daily per capita water consumption was about 56 L, which is approximately one-third of that for students in institutions in the USA. Furthermore, the findings of this study indicated that the average solid waste generation rate was 0.37 kg per student per day compared to 0.31 kg per capita per day when considering the university community (students and employees) collectively. These figures were less and thus compare favorably to the corresponding data for other universities in both developing and developed countries. Originality/value This research addresses the issue of greening JUST campus, which is one of the largest university campuses in the world. JUST campus is located in a semiarid, water-scarce country, which on its own poses a serious challenge. The originality and value of this study mainly stem from the facts that on the one hand, this is one of the unique and pioneering comprehensive studies of its type and, on the other hand, other universities with similar conditions can benefit from the findings of this research to meet the sustainability objectives on their campus operations.

A análise quantitativa da geração de resíduos sólidos no setor de refeições coletivas pode ser usada como indicativo de desperdício em uma Unidade de Alimentação e Nutrição (UAN), prevenindo perdas econômicas e reduzindo o impacto ambiental causado pelos resíduos. O estudo teve como objetivo quantificar a geração de resíduos sólidos em uma UAN inserida em uma empresa do ramo metalúrgico. Foram avaliados os resíduos sólidos durante cinco dias alternados, sendo um dia em cada semana. Para servir 1.407 refeições foram gerados 134.925 g de resíduos sólidos alimentares, resultando em um per capita de 95,89 g/pessoa e 27.114 g de resíduos sólidos não alimentares, per capita de 19,27 g/pessoa. Do total de resíduos, 32,17% foram gerados no pré-preparo; 21,21% foram gerados no resto ingestão; 19,21% foram de sobra suja; 18,80% foram de resíduos não alimentares e 7,90% referentes à sobra limpa. Conclui-se que a UAN apresentou uma quantidade de resíduos sólidos per capita inferior aos valores reportados pela literatura, porém o controle de desperdício deve ser aplicado, constantemente, para dar continuidade na redução do desperdício alimentar e na geração de resíduos. Palavras-chave: Resíduos Sólidos. Nutrição.

Effective solid waste management strategies are recognized as efforts to achieve campus sustainability. The university campus is currently considered the center of various activities involving students, lecturers, staff, and other parties contributing to the consumption pattern of energy, water, and other resources. This study aims to estimate the quantity and compositions of waste generated on the Universitas Diponegoro (UNDIP) campus, identify the causes of waste generation, evaluate the relationships between variables through statistical analysis, and recommend possible strategies to reduce solid waste generation. The results show that the simultaneous contribution of the student-gender ratio, student awareness level, administrative staff background, and green space amounted to 67.7% of the waste generation at UNDIP. Therefore, these four factors need to be a concern for campus authorities in their efforts to handle campus waste. Student awareness in particular was determined to be the only factor that significantly affects solid waste generation. UNDIP may implement proper environmental education through sustainability courses in each faculty to reduce solid waste in higher education institutions since it has the most significant impact. Outcomes of this study could be used as a reference to develop sustainable campus strategies, recycling plans, and comprehensive waste management in higher education.
