Abstract

Intermediate Bulk Container (IBC) is a type of tank used in packaging, shipping & storage efficiently and safely applied to various types of chemical industries made from liquid. However, with a high number of uses and the price of this IBC tank is relatively expensive creating new high cost for industry. IBC with strong and durable material characteristics, has potential to improve its usage. To gain efficiency and positive effects on the environment, the concept of Reduce, Reuse, and Recycle (3R) is the method used by PT DC Cilegon. The purpose of this study is to analyze the reuse of IBC tanks so that the level of efficiency can be expressed in numbers. The data used is the use of IBC in Delivery Note letters for the period of September 2022 to January 2023. The result are 284 IBC was delivered and reused with a ratio of 2.39 times per IBC. Its mean that PT DC Cilegon was increasing efficiency of IBC usage 23,67%. This is the application of the concept of green industry (Green Manufacturing) with focus on Green Supply Chain which has positive impact for environment. Keywords: IBC, Reduce Reuse Recycle (3R), Efficiency, Green Manufacturing, Green Supply Chain.

Abstract

Pompa meningkatkan tekanan fluida. Ada tiga jenis: positive displacement, dynamic (kinetic), dan special effect. Kavitasi adalah penyebab performansi pompa menurun, terutama pada pompa sentrifugal.   Dalam proses pengolahan minyak mentah, kinerja pompa memiliki peranan penting guna menyalurkan minyak mentah maupun produk ke tangki-tangki penampungan di PT XYZ Refinery Unit VI Balongan. Maka perlunya dilakukan analisis peforma pada pompa 42-P-301 A tandhem seal setelah di aligment pada area Oil Movement. Metode yang digunakan dalam analisis performance pompa 42-P-301 A adalah menggunakan proses perhitungan peritungan actual untuk membuktikan efisiensi. Data untuk riset diperoleh dari data sheet dan log sheet pompa 42-P-301A, termasuk Kapasitas/Debit (Q), Suction Pressure (Ps), Discharge Pressure (Pd), Differential Head (H), Daya Poros Pompa saat kapasitas maksimal (P), NPSHr, Diameter Sunction (ds) dan Diameter Discharge (dd). Didapatkan data parameter unjuk kerja dari pompa 42-P-301 A pada bulan Juni didapatkan Head Suction 9,624 m, Head Discharge 49,98 m, Head pompa 42,18 m, Daya pompa 967,45 watt, Daya fluida 781,64 watt, Efisiensi pompa 80,79%, NPSHa 9,19 m, dan Juli Head Suction 10,154 m, Head Discharge 43,98 m, Head pompa 43,10 m, Daya pompa 967,45 watt, Daya fluida 789,68 watt, Efisiensi pompa 82,55% dan NPSHa 9,06 m.

Abstract

This study aims to determine whether pull-up training has a significant effect on the volleyball smash performance of students participating in the extracurricular volleyball program at SMA Negeri 1 Sungai Pinang. The research employed an experimental (quantitative) method with a pre-experimental design, specifically the one-group pretest-posttest design. The population consisted of 12 male students who were active members of the school's volleyball extracurricular activity. The sampling technique used was total sampling. The data collection techniques employed in this study included observation, testing, and documentation. The data analysis technique employed in this study utilized inferential statistics, specifically the Paired Sample t-test, which SPSS assisted. The results of the Paired Sample t-test analysis showed a t-count value of -8.424 with degrees of freedom (df) = 11, and N-1 and a significance value (p-value) of 0.001. The significance value (p-value) is 0.001, which is smaller than 0.05 (0.001 < 0.05). This means that H0 is rejected, and Ha is accepted. Therefore, pull-up training has a significant effect on improving smash performance in volleyball among students participating in the extracurricular program at SMA Negeri 1 Sungai Pinang.
