Abstract

As the primary health reference center, a hospital is required to provide excellent quality services to each patient. The impact of the extreme physical and mental workload cause negligence in activities. It affects the quality of services provided by medical personnel. This study investigated the level of mental workload and physical workload in medical staff in a hospital. This study was conducted at 15 units in the hospital. The mental workload was assessed using the NASA-TLX Questionnaire. The physical workload analysis was carried out with the Heart Rate reserve percentage of medical personnel. The results of this study show that the mental workload on nurses in the ICU is higher than the other units. Whereas the calculation of physical load using% HR reserve turns out the head of the nurse in-unit class 1 has the highest value compared to the others unit. The statistical analysis showed there was a difference in the general practitioner workload toward the Head of the Nursing.

Abstract

This research has a good to plan the product delivery schedule from central ware house to each ware house and from ware house to PT. Coca Cola outlet to minimize the holding number of product. To plan this schedule we implement DRP (Distribution Requirement Planning) method. With using the product demand data, lead time of delivery, holding cost and release cost, also BOD (Bill of Distribution). Then analysis them using DRP software to find the shipping schedule. After implementing DRP method PT. Coca Cola can decrease about RP 7.205.761.500,00 for 8 week.

Abstract

“One Way Convection” is a garment company which produces many kinds of t-shirt based on the customer’s order. In order to fulfill the order, the company applies role of First-Come First-Serve for scheduling the order production sequence. This role is often disadvantageous for the order with short process time because if it is dispatched after the order with long process time, then it will take longer in queue and causes the completion time of all order to be longer. This research aims to schedule t-shirt’s sequence operation in “One Way Convection” company by using Pour heuristic algorithm so that completion time becomes shorter and order fulfillment can be accomplished on-time. The steps in this methodology consist of collecting data, calculating standard time and total process time according to the order, scheduling using initial method proposed by company, scheduling using Pour heuristic algorithm, and comparing makespan of both approaches. According to the Pour Heuristic method, saving is obtained in makespan as 8.09 hours or 19.25% compared with initial method proposed by company.

Abstract

Pembangkit Listrik Tenaga Uap (PLTU) PT Indo Pusaka Berau is a PLN work unit that provides electricity to consumers. The problem of the company is the frequent damage to boiler engine components. The company uses corrective maintenance system. On the problem, it is necessary to develop a machine maintenance system with Reliability Centered Maintenance (RCM) approach. The objective of the study was to select a boiler system maintenance action based on the RCM method and component replacement interval to minimize Total Minimum Downtime (TMD). Results of data processing RCM method, component in category Condition Directed (CD) is El Bow component. Components in Time Directed category (TD) are gland seal steam and check valve. Components in the Time Directed category are calculated for component replacement intervals on TMD criteria. The calculation result from component replacement interval was obtained 37 days for gland seal steam component and 58 days for check valve component. The proposed treatment of RCM method can reduce downtime by 11.33% of the company's maintenance methods.

Abstract

Considering that raw material cost could reach 70% of product cost, supplier selection process was become important consideration to improve the efficiency of procurement department. The supplier selection process was multi-criteria problem involving qualitative and quantitative factors. UD Virgo Bersinar was one of fruit chips manufacturer located in Malang. The company often experienced shortage of jackfruits which interrupt production process. Thus, it was necessary to choose its supplier by considering company’s criteria and order allocation of selected supplier. This research would integrate supplier weight from Analytic Hierarchy Process and Preemptive Goal Programming model to determine priority of supplier and order quantity to the supplier. The model was formulated to achieve two objective functions, namely maximizing total value of purchasing and minimizing total cost of purchasing, by considering capacity of supplier and fulfillment of jackfruit. By running goal programming model, it was concluded that supplier from Semarang would supply 7.5 ton of jackfruit in November 2013-Januari 2014 and deficiency of needs would be supplied by supplier from Tajinan.

Abstract

Genetic Algorithm, Tabu Search, Simulated Annealing, and Ant Colony Optimization showed a good performance in solving vehicle routing problem. However, the generated solution of those algorithms was changeable regarding on the input parameter of each algorithm. CODEQ is a new, parameter free meta-heuristic algorithm that had been successfully used to solve constrained optimization problems, integer programming, and feed-forward neural network. The purpose of this research are improving CODEQ algorithm to solve vehicle routing problem and testing the performance of the improved algorithm. CODEQ algorithm is started with population initiation as initial solution, generated of mutant vector for each parent in every iteration, replacement of parent by mutant when fitness function value of mutant is better than parent’s, generated of new vector for each iteration based on opposition value or chaos principle, replacement of worst solution by new vector when fitness function value of new vector is better, iteration ceasing when stooping criterion is achieved, and sub-tour determination based on vehicle capacity constraint. The result showed that the average deviation of the best-known and the best-test value is 6.35%. Therefore, CODEQ algorithm is good in solving vehicle routing problem.

Abstract

Integrated production-distribution problem resolution using analytical model lacks of consideration of many uncertainties along supply chain line such as delays, queues, machine breakdown, vehicle malfunction, and environmental factor. By utilizing simulation as complex stochastic system modelling, this research aims to develop hybrid analytical-simulation approach to resolve integrated production-distribution model. Time capacity adjustment is required if production-distribution plan obtained from analytical model requires longer production and delivery time than available. The adjustment is using a procedure developed based on duration obtained from simulation model and is used to obtain adjusted time capacity. The implementation of hybrid method to resolve integrated production-distribution problem on two echelon supply chain with 2 factories and 5 DCs shows a feasible solution was obtained on the third iteration
