In recent years, various optimization models related to waste collection system

have been proposed, ranging from the classical mathematical models up to the

latest technology applications that are integrated with real time data. Geographical

Information System is used in studies on waste collection optimization. This

thesis proposed the use of Geographical Information Systems (GIS) modelling

software to optimise the location of containers used for the paper and plastic

waste and describes a method to find the best waste collection route in Pondok

Pinang, Kebayoran Lama District, South Jakarta. The results of study showed that

the spatial analysis model which combines the range of influence grid mapping

with road network system can be used to find the optimum number and location of

containers for plastic and paper collection systems in Pondok Pinang. The

optimization of waste collection route can be modeled through a modified concept

of network analysis by combining and converting the parameters of the waste

characteristic and transportation system into the time dimension which is used as a

impedance factor. In addition, the weighting parameter analysis can be used as an

alternative method to determine the impedance in the routing model."

"Pertumbuhan jumlah volume sampah pada TPA Bantar Gebang cukup pesat, sehingga lambat laun beberapa lahan akan di non-aktifkan akibat kapasitas yang sudah maksimal. Berdasarakan hal tersebut, lahan tersebut akan ditutup dan masih menjadi lahan kosong yang seharusnya dapat dijadikan tempat yang mendukung infrasturktur. Namun, untuk melakukan pembangunan pada lahan tersebut diperlukan data-data mengenai material yang mendukung. Di indonesia, data mengenai timbunan sampah, khususnya data geoteknik, masih sangat kurang. Oleh sebab itu diperlukan pengujian yang berdasarkan pada pengujian dibidang geoteknik. Pengujian geoteknik yang akan dilakukan adalah pengujian dengan menggunakan sampel artifisial dengan menggunakan alat uji triaxial.Pengujian triaxial dilakukan dengan memadatkan sampel terlebih dahulu dengan menggunakan tiga variasi energi pemadatan modified proctor untuk mendapatkan kuat geser dari sampah. Hasil yang diperoleh menunjukkan bahwa semakin besar energi pemadatan yang diberikan, maka akan semakin besar nilai parameter yang diperoleh. Dari hasil parameter yang diperoleh dilakukan pemodelan menggunakan slope/w untuk melakukan validasi terhadap parameter yang diperoleh. Hasil yang diperoleh menunjukkan bahwa nilai parameter masih belum sesuai dengan kondisi eksisting.

Increasing number of waste volumes in Bantar Gebang landfill nowdays increase rapidly, because of that some of the field will be disabled/deactivated as a result of the field have reach a maximum capacity. Based on that situation, the land will be closed and become an empty land that can be used as a productive land that could support the infrastructure development. However, to develop something on that land required data about the material that could supports the construction. In Indonesia, we still have not much data about the landfill waste, especially for geotechnical data. Therefore, the tests based on geotechnical field is required to collect the support data. Geotechnical test that will be done by using artificial samples with the triaxial test equipment.

Triaxial testing conducted by compressing the sample by using three variations of modified proctor compaction energy to get the number of the shear strength of waste. The results obtained showed that the greater the compaction efforts is given, greater the parameter values ​​obtained. From the results of the parameter we obtained, we make a model by using software slope/w to validate the parameters obtained. The results showed that the value of the parameter is still not in accordance with the existing condition."

"Based on the information technology rapid improvement, it can be predicted that computer waste generation in Indonesia is quite high. Compare to individual users, corporate users do easily change their old devices with the latest ones. Thus this research is focused on corporate users, in this case PT. Bank Rakyat Indonesia, Tbk. (BRI). To provide the best service to the clients, IT equipments are the first preference to process and store data. However IT equipment ?computer desktop, used in this research- has such a short life-span, 5 years maximum. The need for the latest and highly improved devices is backed up by the sufficient fund hence BRI is potential enough to cause the increasing of computer waste generation. Waste minimization by 3R must be conducted, since computer waste contains of many hazardous substances that can cause environmental pollution and give horrible impact to human. On the other hand, waste minimization through computer waste recycling cause negative impact to the worker and people live nearby the recycling site. So that this research is dedicated to reach the objectives, which are: 1). to identify the life cycle of BRI?s computer, 2). to identify the BRI?s potential of computer waste generation, 3). to provide an analysis on the advantages and the disadvantages of computer refurbishment and computer waste recycling. To methods used for achieving first objective are partially life cycle assessment and interviews to BRI logistics staff. The next objective is reached through inventory analysis and impact analysis. For the last objective, the methods used are improvement analysis and interviews to BRI staffs, collector, recyclers and staff of Environmental Ministry. All objectives previously analyzed through literature reviews.The research found that since 2007 BRI has no longer used their own computers, but rented computers instead, therefore the life cycle of BRI computer is described within two parts. First, the life cycle of BRI computers, started from the use by BRI and the computers will be released through public sale to the society/collectors before the scrap computers find their final destination to the recyclers. In each step of xii the way, there will be waste generated. Second is the life cycle of rented computers. It begins from the vendors and then to BRI, next if the computers are no longer used the vendors possibly sell, rent out or sale them to public. The potential waste generated from BRI?s computers is approximately 925.7 tons of solid waste, contains of hazardous substances. The numbers were calculated based on BRI assets. Based on 5-year hardware lifespan, estimated potential waste generated would be 329 tons of solid waste in 2008 from 12.667 PCs, 180 tons from 6.948 PCs in 2009, 68 tons from 2.647 PCs in 2010, 49 tons from 1.892 PCs in 2011. BRI computers would reach to an end on 2012 by generating 32 tons of solid waste from 1.227 PCs. Potential solid waste generate by rented computers is estimated 54,6 tons/yr. Computer waste generated by public sale of scrap computers from 2005 to 2007 is about 103 tons. The effort to minimize impacts to the environment is waste minimization, refurbishment and recycling. The refurbishment on used corporate computers is slightly possible since the used computers sold are already in totally unusable.Despite the business and job opportunity given by computer waste recycling, there are also some obstacles in the process, which are: insufficient technology, no regulation and monitoring, no coordination; and high operational cost. The suggestions given are: 1). Use the rented computers wisely, 2). Polluters pay principle must be considered to be applied 3). It needs a good design on computer waste management, such as waste exchange that provides informations, accommodates the legal procedures and transportation. During the recycling operation, there must be adequate monitoring, to make sure the residual waste is handled and to monitor the worker health. To minimize the waste from the source (producers), it is suggested that BRI keeps being commited using ecolabel rented computers, so it will give pressure to the producers to manufacture green products."
