IOSR Journal of usiness and Management (IOSR-JM) e-issn: X, p-issn: Volume 19, Issue 6. Ver. V (June 2017), PP R Implementation in Waste Management at PT. PJ UP Muara Tawar Miradha Herdini Widiatmi 1, Syaiful Amin 1, Ridho Prima Oktansyah 1, Awang Asmoro 1, Kevin Sanjoyo Gunawan 2, Totok R. iyanto 2* 1 PT. PJ UP Muara Tawar, Muara Tawar, Indonesia 2 Engineering Physics Department, Institut Teknologi Sepuluh Nopember (ITS), Surabaya, Indonesia. Abstract: The waste problem are also an important issue for PT. PJ UP Muara Tawar power plant. The waste can contaminate the rain and river water, then flow to the sea. As we know, the power plant condenser utilize sea water as cooling fulid. The sea water will flow through pump and filter. The waste contamined in water sea has posibility to clog the intake of filter. As point of view from management of PT. PJ UP Muara Tawar, the sea water pollution due to solid waste can affect the operation and maintenance of power plant, meanwhile, it can impact to the society health awareness. Hence, this program is very important to the company and society and it is in line with Sustainable Development Goals (SDGs) i.e. clean water and proper sanitation . This program was initiated by PT. PJ UP Muara Tawar and it is perfomed by employment with the main objective improve clean environmental and society healthy. Waste reduction is done by reduce the use of objects that can generate waste, waste disposal according to type, and advanced processing of waste such as composting. This program have been succesfull implemented. From this program the amount of solid waste are reduced. waste are reduced by 0.8 ton in 2013, 511 ton in 2014, 401 ton in 2015 and 271 ton in Inorganic waste are reduced 19 ton in 2013, 529 ton in 2014, 418 ton in 2015 and 279 ton in Keywords: inorganic waste, health, non-hazardous, non-toxic, organic waste I. Introduction Solid waste/garbage problems in ekasi District are still an unresolved problem. The waste increase over the time due to increase in population and human activities [1]. Waste processing requires some facilities [2]. However, the capacity of processing facilities less than waste volume. In order to overcome this matter, some people in Segarajaya Village area, especially at Kampung Mandalajaya, Kampung Paljaya, and Kampung Kaliadem burn the waste. This solution increase air pollution [3]. The waste problems also an important issue for PT. PJ UP Muara Tawar power plant due to contamination in rain and river then flow to the sea. As we know, the power plant condenser utilize sea water as cooling fluid. The sea water will flow through pump and filter, and the waste contained in sea water has possibility to clog the intake of filter. As point of view from management of PT. PJ UP Muara Tawar, the sea water pollution due to solid waste can affect the operation and maintenance of power plant, meanwhile, it can impact to the society health awareness. Hence, this program is very important to the company and society and it is in line with Sustainable Development Goals (SDGs) i.e. clean water and proper sanitation [4]. This program was initiated by PT. PJ UP Muara Tawar and it is performed by employment with the main objective to improve clean environmental and society healthy [5]. Waste reduction was carried out by reducing the goods that can produce waste, waste classification, and advanced processing of waste such as composting. y this program, it is expected that nonhazardous and non-toxic solid waste can be reduced. II. Theory Waste management can be carried out through reuse, reducing, and recycle (3R) the waste. Reuse is utilization of waste for the same or other functions while reduce is the effort of reducing waste by decreasing goods consumption, and recycle is reprocessing the waste for other purposes [6]. Sources of waste can vary from households, markets, stalls, offices, public buildings, and industries. ased on their chemical composition, the waste is divided into organic waste and inorganic waste. Research on solid waste in Indonesia shows that 80% waste is organic waste, and it is estimated that 78% of the waste can be reused [7]. Waste management is all the plans and actions to reuse, reduce and recycle the waste before final disposal [8]. This includes collection, transport, treatment and disposal of waste as well as monitoring and regulation. It also encompasses the legal and regulatory framework that relates to waste management including guidance on recycling etc. DOI: /487X Page III. Method The integrated waste processing program requires several resources, including human worker as garbage collector and administrator. Another resource is the facilities for garbage collection, sorting, washing and pressing, such as carts, trash cans, scales, etc. The program is performed by the following stages: 1. Waste disposal according to its type. y this stages it easier to select the waste that it can be processed or not. Fig. 1. shows garbage bins with 4 type of waste i.e. paper waste, battery, metal, and other waste. Figure 1. Garbage ins by Type of Garbage 2. Processed waste is plastic and paper waste. Unprocessed waste will be collected and sent to the landfills by district government. 3. Plastic waste will be washed in the tub to remove dirt and put into the washing machine for further cleaning process. 4. Paper waste are collected to change with new paper. y this program it is expected that paper waste will be reduced. Fig. 2. shows the collected waste paper in Muara Tawar office room. Figure 2. Water Reuse in Muara Tawar Office 5. waste are processed to make a compos. There are composting facility in Muara Tawar. Figure 3 shows the composting facility in Muara Tawar. Figure 3. Composting Facilities in Muara Tawar DOI: /487X Page IV. Discussion In implementation of the program, it show that non-hazardous and nontoxic waste can be reduced. The practice of waste reduction by reducing the use of paper shows a good result. Table 1. shows inorganic and organic waste before implementation of waste processing in period. It shows the use of paper is reduced per year. Table 1.

Paper Waste Reduction and Utilization Graphic Reduce and utilization of waste from implementation of this program is shown in Table 2 and Table 3. Table 2. shows the waste reduction has been increase per year. It is shown that reduction of waste program successfully implemented. From 2013 to 2014, the waste reduction is increase ton of waste per year. From 2014 to 2015, the waste reduction is increase ton of waste per year. Table 2.

It is shows that the waste are reduced by implementation of this program. In 2013, before utilization and reduction of waste, total of waste sent to landfill are 1570 ton. After implementation of program, the total waste sent to landfill are reduced to 1551 ton. In 2014, before utilization and reduction of waste, total of waste sent to landfill are 2136 ton. After implementation of program, the total waste sent to landfill are reduced to 1607 ton. In 2015, before utilization and reduction of waste program, total of waste sent to landfill are 2045 ton. After implementation of program, the total waste sent to landfill are reduced to 1627 ton. Therefore, implementation of this program are successful. Table 4.
