Distribution center has an important role in an industry's supply chain management to facilitate logistics management requirements so that the product distribution process becomes smooth and fast. The purpose of this study is to determine the best location that can be used in determining the location of the distribution cente in pharmaceutical industry.  This research uses the center of gravity method to calculate optimal location that will be considered. From the results of this study, the calculation using the Center of Gravity method found that the location of the selected distribution center was at the coordinates (-6.257108; 106.7315), the settlement area of the village of Jurangmangu Timur. The available area according to warehousing rules does not allow the construction of the distribution center in residential area of Jurangmangu Bintaro village, empty area is available around 4 KM west of T8 Pakulonan Alam Tangerang Selatan, this area provides warehousing by offering a combined trading center, office and integrated food and beverage plaza with shelter have advantages as distribution center. The new proposed distribution center location is located 14 KM south and 13 KM from the north of the available warehouse, the new suggested location is closer to and located between current distribution locations.

Pengukuran massa banyak dilakukan menggunakan timbangan konvensional, tetapi sistem ini memiliki kelemahan diantaranya adalah keakuratanya rendah dan kurang efisien waktu kerja.  Hal ini dikarenakan harus  memindahkan tembakau dari timbangan manual menuju alat press tembakau dengan tempat kerja yang terpisah. Penelitian ini bertujuan untuk merancang dan membuat sistem kontrol penimbangan tembakau menggunakan sensor  load cell. Metodologi yang digunakan dalam perancangan dan pembuatan sistem penimbangan tembakau dengan sistem kendali Arduino Uno, pertama adalah. proses perancangan, gambar desain sistem kontrol, diagram blok sistem kontrol, pembuatan dan pengujian. Hasil penelitian adalah telah dibuat sistem penimbangan tembakau dengan keakurasian tinggi, presentase ketelitian dari timbangan adalah 99,8 %._Kata kunci:  timbangan, loadcell, arduino Uno
