Abstract

Turn over ratio (TOR) is the ratio between expenditure/usage/sales to inventory. The higher TOR means the faster inventory turnover, which also means that the utilization of investment is higher or more efficient. The lower TOR means that capital turnover or investment is slower and less efficient. The purpose of this research was to determine the performance of the inventory of production machinery spare parts in the warehouse through the inventory turnover ratio. This research uses quantitative analysis. There are 435 types of spare parts in the warehouse, but only 63 types were used during the observation period. The result showed that the performance of spare parts inventory had various inventory turn over ratio, which ranged from 0.01 – 48.00 times during the period January, 1st – June, 15th 2018 or ranged 0.03 – 100.70 cycle per year. While the storage time of spare parts inventory ranged 2.98 – 11.368.50 days.

Abstract

The problem that often occur in the inbound process in the warehouse are process of unloading and late document making process and error in the process of inputting data in a computerized system. This ptoblem cannot be solved carefully is the root cause is not analyzed. The purpose of this research is to find out the deviations that occur in the inbound process, the root cause of the problem and solution. This research was conducted on February 22nd, 2018 – May 22nd, 2018 at a logistic company in Bekasi. Data analysis was processed by Deming’s View Process System concept, the 5W + 1H principle and the Five Whys Analysis. The result show that the root causes of problem are: 1) the supervisor and the assistant manager less supervision on the workers in the inbound section; 2) the supplier does not check the document when it will deliver the cargo; and 3) the workers have never been rewarded for their work. The solution is: 1) the supervisor and the assistant manager must supervise the workers in inbound section continuously; 2) the supplier must check the cargo and documents before being delivered the warehouse; and 3) the company must give a reward to the worker’s performance.

Abstract

This research discusses the use of Value Stream Mapping (VSM) to analyze waste in the process of sending Purchase Order (PO) and Goods Received Note (GRN) documents. The purpose of this research is to determine the existence of waste in the flow of the document delivery process and make improvements to the things that cause the waste. This research was conducted on April 2nd - July 14th, 2018 at a distribution company located in Kabupaten Bekasi, West Java. The object of research is focused on the process of sending PO and GRN documents to vendor in the Department of Transportation and Distribution. Data gatering was carried out through observation of object and interview with sources, namely parties related to the object of research. The data analysis method used was VSM analysis with the following steps: 1) making Current State Mapping; 2) calculation of Process Cycle Efficiency (PCE); 3) making Process Activity Mapping (PAM); and 4) making Future State Mapping. The result showed that there were waste activities, ie excess processing, waiting and motion. The proposed improvement concept were: 1) reducing the approval process time; 2) create a procurement checkpoint; 3) eliminates the waiting time for the confirmation process; 4) eliminating waiting time for approval process; 5) eliminating approval; 6) eliminates the process of waiting for delivery of documents to vendors; and 7) establish a FIFO system for document delivery to vendor.

Abstract

This research discusses controlling the gap of Actual Processing Time and Ideal Processing Time in a palm oil mill (PKS). The purpose is to find out how the gap of the two processing times for palm oil in the PKS and how the losses experienced by the company with these conditions. This research uses the individual moving range (I-MR) Chart method. The test is carried out first with the MR-Chart, and will be revised if there is an out-of-control condition. Next will be testing the condition of the time gap with the x-Chart. In the event of an out-of-control condition, a process capability measurement (Cp) will be carried out. The result showed that the PKS studied had poor gap processing time, although the gap that occurred were still within reasonable limits in accordance with the performance of the PKS. However, this condition still results in considerable losses for the company because it has to incur more operational costs than it should.
