“…Peta Kecamatan Mustikasari maka penelitian terhadap kualitas air tanah ini dilakukan dua wilayah yang berbeda secara rutin dengan jangka waktu yang sama. Banyak data-data hasil penelitian kualitas air di Bekasi yang telah dilaporkan sebelumnya (Astuti, 2015, Izzati et al, 2016b. Tujuan Penelitian ini adalah Untuk melihat dan membandingkan kualitas air tanah di daerah yang memiliki sumber pencemar yang berbeda dan air sesuai wilayah tersebut.…”

Tujuan penelitian ini adalah untuk mengetahui pencemaran air berdasarkan beberapa parameter kadar pH, TDS (Total Dissolve Solid), EC (electrical Conductivity), dan temperature air dari dua sumber mata air, yaitu satu lokasi di daerah Industri dan dua di daerah pemukiman penduduk dengan metode pengambilan sampel air secara rutin setiap hari selama dua bulan. Dengan hasil rata-rata untuk air tanah industri adalah : pH 8.19, TDS 194.50ppm, EC 378.75µs, dan temperatur 26.61oC. Sedangkan untuk daerah pemukiman adalah : pH 8.08, TDS 265.36ppm, EC 435.18µs, dan temperature 25.46oC. Berdasarkan data diatas dapat disimpulkan bahwa kualitas air di Pemukiman dan di Kawasan industri masih layak untuk dikonsumsi. Hal ini mengacu pada Peraturan Menteri Kesehatan Republik Indonesia No. 32 Tahun 2017.

“…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.

“…Because the industrial environment is growing so fast, research should be done regularly to check the industry's impact on water quality [3][4][5][6]. Bogor areas is close to Jakarta, which has many pollution studies [7][8][9][10][11][12][13][14][15], Bogor itself has been studied for the open space and pollution [9,16,17]. The open space research was supported by the study of social welfare and young generation under the Ministry of Young and Sport Of Republic Indonesia [18][19][20].…”
