Abstract

The present for green campus in University of PGRI Semarang is not only emphasizing on greening the campus, but also green living lifestyle that is green in everyday life. The concept of recycling for garbage which commonly referred as the 3Rs (Reduce, Reuse, Recycle) is solution that can be considered, so that the economic value contained in garbage can be utilized. This study aims to analyze the volume and composition of waste from the existing condition of the operational techniques of waste management to optimize its development prospects through an action plan on the campus of the University of PGRI 3, Bendan Duwur Semarang. Data collection methods used were interview, observation and simple random sampling. The data is analyzed qualitative descriptively. The results showed that the calculation of the average volume of waste resulting from activities that occur on campus 3 Bendan Duwur UPGRIS is mostly obtained as much as 88% category leaves, twigs litter composition of 4.5%, 4.45% waste paper and plastic waste 2.51%. Largely organic waste, because at this location there are many teak trees. The amount of inorganic waste is very small because that place is not exclusively used for all lectures, but it mostly used for laboratory activities. From the analysis, it will be designed an action plan for waste management on campus 3 Bendan Duwur PGRI University, including the separation process waste from its source, measurement of waste generation and waste composition continuously, design of technology for the processing of organic waste appropriately therefore produce economic value product.Keyword : garbage, 3R, generation volume, the action plan.

Abstract

Plastic is materials for packaging that is widely used today, because it has many advantages such as tough, light, and stable enough. However, the plastic used mostly in market are synthetic polymers which is made from crude oil and is difficult to decompose in nature, therefore, it can be increased environmental pollution, especially makes several waste in soil. One of many alternatives for recycling process is to convert waste plastics into fuel oil as for alternative energy source. This recycling process is referred to as tertiary recycling. Several studies aim to determine the characteristic of fuel oil from LDPE and PVC plastics that are applied to engine, so that can substitute a premium or diesel fuel used previously. Research methodology generally include two phases, namely the process of thermal (thermal cracking) and the addition of catalysts (catalytic cracking). The primary outcome of the studies are the optimal methods in fuel manufacture with raw materials LDPE and PVC plastic types with homogeneous catalysts based on modified natural zeolites with Ni and Cr for cracking waste plastics.Keywords: LDPE, PVC, Thermal, Catalytic, Cracking.
