“…dry leaf do not shrink but only rolling (flexible) and dry leaf shrinks, rolls and brittle. Since the environment impact of waste and waste management of indutries and its area in Indonesia have been informed in many reseach studies [14][15][16][17][18][19][20]. In this reserach, the waste of patchouli leaf is not include in the consideration or mesaurement.…”

The aim of research is to design the model of rendement rate by considering the criteria of patchouli leaf and designing a good supplier selection model to maximize the company profit by considering the acceptance of the patchouli oil rendement rate. The selection of suppliers discussed is to consider the quantity of goods offered by suppliers, demand, budget and acceptance limitation of rendement rate. To overcome these limitations, it is necessary to develop a supplier selection model that takes into consideration the quantity limitation of goods offered by the supplier and the acceptance of the rendement rate by using Linear Programming (LP) method. The result of the research shows that the determination model of the rendement rate developed to determine the percentage of Rendement Rate (RR) of each raw material supplied by the supplier so that the company can know the quality of patchouli leaf based on the type of patchouli leaf. The analysis result of numerical sample calculation shows that the selected supplier is not a supplier with good patchouli leaf criteria, the analysis result of parameter changes in oil demand and budget indicate that when oil demand is increased over the benchmark data, the model output is insensitive, but when demand is lowered below the benchmark data, the model output looks sensitive.

“…If the water is polluted, and has a pH value below normal due to contamination from waste produced by industries, households and transportation, the water becomes unfit for consumption by local people [5,8] especially according to the open space to reduce pollution [9]. In the other hand, some studies have been reported regarding to these urban pollution and surrounding it in separated research [10][11][12][13][14][15]. Since the environments are growing so fast, the studies have to do regularly to examine the effect of population and industries to the acidity of water.…”

“…There are several important factors that determine the quality of the water in all regions in Indonesia this, factors such as acidity (pH), electrical conductivity (EC), total dissolved solid (TDS), and temperature of water [1][2][3][4][5]. Many pollution data have been reported in some journals, especially in the area surrounding the capital city, Jakarta [6][7][8][9][10][11][12][13][14][15]. In addition, the social welfare and the limitation of open space have been studied in Cibubur, close to Jakarta, with the support of the Ministry of Young and Sport Of Republic Indonesia [16][17][18].…”
