Municipal solid waste (MSW) generated by the dwellers of the City of Bandung which amounted to 7500 m3 per day is big deal of a problem for the Government of the City since MSW treatment and management is carried out by the Government business branch (PD Kebersihan). The Government has decided to implement waste to energy (WTE) incineration for MSW treatment three years ago. The realization, however, was nowhere to be seen. One of the reasons that the realization is halted is due to the objection by residents in the neighbourhood of the planned WTE plant site. This paper aims to systematically and objectively assist and support the decision makers in the Government in selecting the most appropriate MSW treatment technology and management for the City via implementation of sound multi criteria decision analysis (MCDA) tools available. Herein, the MSW treatment technology and management regarded as alternatives are open dumping landfill, sanitary landfill, power generation from biogas via anaerobic digestion, power generation via gasification, composting, and waste to energy (WTE) incineration. Moreover, aspects of technology, social, economy, and environment are considered as criteria for selecting the most suitable MSW treatment technology and management. Several well established MCDA tools such as AHP, ELECTRE II, PROMETHEEII, and TOPSIS are applied. Each of the MCDA tool has its own merits and drawbacks which will be investigated in this paper. In addition, sensitivity analyses were carried out in order to investigate the robustness of the methods. Among all MCDA tools mentioned, TOPSIS is the simplest to be used for it does not need much intervention from the decision maker, and yet yields comparable results with others.

Development of Industry-Oriented Master Degree Program in Mechanical Engineering at Institut Teknologi Bandung: lessons learned 2

The Mechanical Engineering Department at Institut Teknologi Bandung (ITB) was established in 1941 during the Dutch colonial rule as the first mechanical engineering program in Indonesia. The Master's Degree program in mechanical engineering was added to the Study Program much later in 1987. Both programs (Sarjana and Master's Degree Programs) have been awarded an 'A' grade from the Indonesian National Accreditation Board/Badan Akreditasi Nasional (BAN). However, over the years participation in the Master's Degree program has been low, with an average of less than 20 students per year. The stringent application requirements to enter the program and the lucrative salary packages offered by the industries might be the most common reasons why people refrain from pursuing a Master's Degree that requires them to spend a 1.5 to 3 years of study time. Since 2008, two new approaches have been introduced into the Master's Degree program. First, the Fasttrack Program, which allows high-achieving students to accomplish both the Sarjana and Master's Degree programs in 5 years. The other is called Credit Earning Activity (CEA), which allows industrial employees to attend the Master's Degree program without having to retire or take a leave from their work. This paper discusses the experiences and lessons learned from 25 years of administering the Master's Degree Program in Mechanical Engineering at ITB. Several efforts have been made to improve the quality of the program.
