Model Dinamika Sistem Pasokan dan Distribusi pada Gangguan Pendistribusian BBM PT. Pertamina Padang
Get PDFThis paper discusses supply and distribution Bahan Bakar Minyak (BBM) system at PERTAMINA Padang to look a performancy system that disturbance of distribution like replacement Automatic Circuit Breaker (ACB). The replacement of ACB processes about 12 hours and causes the distributing activity of BBM to Stasiun Pengisian Bahan Bakar Umum (SPBU) has to be stopped. It makes impact toward the work ability of supplying and distributing system. Therefore, a planning model which is able to see the impact of ACB replacement toward system behavior of supplying and distributing is needed. Purpose of the modelling is to study the behavioral effects of variable in supply and distribution system using causal loop diagram and stock flow diagram. Result of this diagram has built simulation model to analyze performance system. Verification testing done by the method of checking the level and flow and testing of the coding. Validation of the model while the testing is done by operational graphics and the variability parameter sensitivity analysis. The model was designed and carried out the design of simulated scenarios to determine a strategy for decision-makers to look at the performance of BBM supply and distribution system.

Get PDFSmall and medium enterprises in Indonesia gave big contributions to create job opportunities for community and increased Gross Domestic Product. Unfortunately, the current SMEs did not get any respect from the government. This is evidenced by many problems that happened with SMEs in Indonesia. Agency Statistic Center conducted survey in 2009 and 2010 and identified causes of the problems are availability of raw materials, financial problem, marketing, fuel or energy, transportation, skills, payment and many others. Formulation of the problems is how to design indicators of innovation that can be used to make policy strategies to solve the problems. The objective of research is to recommend some innovation indicators for spare part in Padang and use the indicators to make innovation policies. Method to determine the ability innovation of spare parts industries is Quality Function Deployment (QFD). The first stage is identify consumer needs. Consumer needs obtained from literatures and interviewed of stakeholders. Then, calculated based on customer importance ratings to obtain critical and non critical indicators. Indicators will be presented into the House of Quality (HOQ). The results of HOQ are determined some strategies by using SWOT analysis. This research result obtained 25 innovation indicators of technology that is divided into three aspects such as technology aspects, design and product quality aspects. Strategy formulation from SWOT analysis result some strategies with 4 categories and among of them are SO strategy (4 strategies), WO strategy (5 strategies), ST strategy (4 strategies), and WT strategy (3 strategies). Besides that, strategy architecture will present strategy implementation for 10 years and completed with some people that have participation to make this strategy implementation successful

Investigation of Lower Limb Fatigue on Two Standing Posture
Get PDFThe purpose of this study was to investigate the different effect from the two standing posture on lower limb fatigue and discomfort. Sixteen subjects (eight females and eight males), aged between 23-29 years, participated in the experiment. They performed a sorting task in front of a grading table by picking and placing objects for 90 minutes in two posture (1) standing and (2) standing using a footrest. Muscle activity was recorded with surface EMG through disposable electrodes. The result shows that standing for ninety minutes developed fatigue in lower limb muscles and back muscles that lead to low back pain. Standing using a footrest result proper posture for prolonged standing period and reduce force at the back. It also results less fatigue and reduce the %MVC of EMG. So, it is recommended to attach a footrest in standing workstation to reduce the fatigue and discomfort

Analisis Penerimaan dan Pengeluaran Barang Umum Non Curah Pada Gudang Perbekalan PT. Semen Padang
Get PDFInventory has its advantages and disadvantages. The advantage of this inventory is to beable to anticipate the urgent needs of the company, meet the demand from users. But thisstock has a loss, which can increase the costs to be incurred by the company so as to reducethe advantage held by the company. The more the amount of inventory in warehouse, themore the cost of inventory that must be removed and inventory turnover (ITO) whichproduced the lower. One way to do inventory control is to determine the optimal orderquantity. The method used to determine the optimal number of reservations is to use theEOQ method by considering the amount of safety stock and reorder point when done. Basedon the calculations have been performed for the optimal order quantity are 2,019 bottles ofoxygen, welding wirerod is 14,795 stems, and 185 stem of pipe metal. By doing of EOQ toinventory control obtained by the method of ITO increases the weld wire and pipe metalfrom 0.0392 to 1.1010 at the welding wire and from 0.2949 to 0.8627 on a pipe metal.However, the oxygen has decreased from 1.9238 to 1.6094 so that it can be concluded thatthe EOQ method can not be applied to the oxygen, but can be applied to the weldingwire and pipe metal
