Penelitian ini bertujuan untuk membahas analisis tata letak fasilitas display retail fashion pada PT. Kindo Ritel Prima (Pointbreak Store). Analisis ini dilakukan menggunakan pendekatan Metode Activity Relationship Chart (ARC) dimana ada 2 tahapan yaitu ARD dan ADD. Dari 9 departemen terdapat 4 departemen yang mengalami perubahan sehingga menjadi alternatif untuk perbaikan. Departemen (1) space area kasir mengalami perubahan yang diletakkan di tengah berdekatan dengan area gudang dan vitting room agar memudahkan dalam pengawasan semua aliran proses jual beli. Departemen (2) area gudang mengalami perubahan yaitu penggabungan antara 2 gudang menjadi 1 bertujuan untuk pengelompokan stock gudang dan memudahkan dalam proses penyusunan serta pengambilan barang. Departemen (3) vitting room mengalami perubahan ukuran yang sedikit lebih besar untuk membuat pelanggan lebih nyaman dan juga penyatuan dalam 1 area agar tidak membingungkan pelanggan dalam mencari kamar pas untuk mencoba produk. Pada space area layout awal mempunyai ukuran luas 50.14 m², setelah perbaikan layout alternatif ukuran luas space area menjadi 46.5 m². Maka ada space area yang dapat di minimalisirsebesar luas 3.64 m².

Tata letak adalah suatu cara dalam mewujudkan pengaturan fasilitas supaya optimal yang bertujuan dalam meminimalkan biaya produksi dan meningkatkan produktivitas. Tata letak yang tidak tepat seperti jarak gudang ke mesin cetak yang terlalu jauh akan berdampak pada pemborosan waktu proses produksi. Penelitian ini bertujuan untuk mereview tata letak percetakaan koran PT Sumsel Media Grafika dengan pendekatan metode activity relationship chart (ARC), dimana di dalam ARC terdapat 2 tahap yaitu ARD dan AAD.  Hasil penelitian didapatkan hasil bahwa dari 10 departemen terdapat 4 departemen yang mengalami perubahan sehingga menjadi prioritas perbaikan, sehingga layout awal  yang semula menggunakan area 750 m2 menjadi 450 m2 jika menggunakan layout alternatif. Sehingga area sisa seluas 300 m2 dapat disewakan.

Abstract—This study aimed to determine the optimum concentration of natural coagulant from chitosan to reduce the concentration of TSS in the skin cracker industrial liquid waste. The test was carried out by mixing chitosan powder which had been dissolved in 1% acetic acid. The treatment was carried out with variations in coagulant concentrations of: 100, 150, 200 and 250 mg/L added to several samples, namely the initial TSS concentration of liquid waste obtained from the initial measurement of liquid waste taken at 3 positions of waste disposal sites, namely 500, 570 and 650 mg/L. The results showed that the TSS concentration of 500 mg/L and the addition of 100 mg/L coagulant produced a concentration of 110, 150 mg/L coagulant produced 65 mg/L, 200 mg/L coagulant produced 90 mg/L, 250 mg/L coagulant reached 110 mg /l. At a TSS concentration of 570 mg/L, add 100 mg/L to 122 mg/L, coagulant 150 to 68 mg/L, coagulant 200 mg/L to 89 mg/L, coagulant 250 mg/L to 95 mg/L. TSS concentration of 650 mg/L was added 100 mg/L to 130 mg/L, coagulant 150 mg/L to 76 mg/L, coagulant 200 mg/L to 90 mg/L and coagulant 250 mg/L to 111. Conclusions from the study This shows that the most optimum reduction of TSS concentration is the addition of 150 mg/L of chitosan coagulant which can reduce the concentration of TSS in the skin cracker industrial waste water by 88.3%

PT. Y is a company engaged in the processing of fresh palm fruit bunches into Crude Palm Oil (CPO), and has a production capacity of 30 tonnes/hour. The CPO production system generally goes through a long process and there are several processes that are not optimal. One of the processes is pressing, where this process experiences a lot of oil loss. Oil loss experienced at PT. Y of 6.28 to 6.32 percent of total production. Therefore, it is important to identify the causes of oil loss in the pressing process so that it becomes a preventive measure and can reduce the percentage of oil loss during the production process. The purpose of this research is to identify the factors that cause CPO oil loss and to recommend solutions to minimize CPO oil loss in screw press machines using fishbone diagrams. A fishbone diagram is used to identify the root causes of problems in a process. The cause of the problem is often caused by five elements, namely Man, Method, Machine, Material, and Environment. Fishbone diagram is useful for finding the factors that cause a problem. The results obtained from the fishbone diagram are several factors that cause oil loss in the pressing process or in the screw press machine including machine factors, raw materials, humans, and method factors. Recommendations that can be implemented by companies include routine maintenance of screw press machines, both corrective maintenance and preventive maintenance, it is necessary to control the quality of fresh fruit bunches from the beginning of harvest until the fruit reaches the loading ramp station, and this requires training so that operators can better understand how to machine operation.
