Study of waste management towards sustainable green campus in Universitas Gadjah Mada

Waste management is a part of the green campus achievement program. Universitas Gadjah Mada has a Standard Operating Procedure for managing produced waste. Waste produced by each building or work unit is temporarily accommodated in the waste depot before dumped into the landfill. This research aims to study the waste management system in UGM, in accordance with the concept of a green campus. The concept of green campus to improve the efficiency of waste management needs to be supported by various parties. The success of the green campus program relies on an integrated approach, a sustainable implementation that involves stakeholders of the university. In actualizing the concept of a green campus, the university has its own waste processing system. The organic produced waste is processed into compost, while plastic waste is converted into alternative fuel. Overall, the waste management system that UGM owns is ineffective and inefficient, it was proved by the fact that there is still much waste dumped into the landfill. UGM provides a laboratory that is specialized to process waste that is produced by UGM. It is planned to be able to reduce the amount of waste that is dumped into the landfill. According to the results, vermicomposting technology, the manufacture of liquid fertilizer from leachate, and the manufacture of the composite from a mixture of leaves and paper were offered as solutions.

The effect of spatial configuration in the thermal area of Fort Oranje public space in Ternate City

Crowded city will be impact to the temperature of urban areas. This condition is commonly known as the urban heat island effect. It’s impact to the activity that happened in the urban space. Recently, Fort Oranje (urban space/square) that has history value has been revitalized as an urban public space that is crowd visited by Ternate’s people. Therefore, the thermal comfort becomes an important thing and that is available to the users. The research is aim to know the influence of space configuration change to the aspect of thermal comfort in the urban public space. The method that is used in this research is empirical measurement and simulation method using Envi-MET software. This method is used to simulate the condition of thermal area in Fort Oranje. The result of this research showed that space configuration that change before and after the development of Ternate waterfront city impact to the thermal conditions in Fort Oranje public space.
