Abstract

CV. ABC is one of company that offers services on package delivery. Based on observation wasconducted during the months of January up to August in 200x was found tardiness around 2.5% average per month.The type of delivery service that having the highest level of tardiness is the ONS (Overnight Service). This research is aim to design a model of performance measurement and to compile system proposal of supply chain to minimize the tardiness of ONS’s system in CV. ABC. The model was developed from previous result such as Bowersox & Closs (1996), Simchi-Levi et. al. (2000) dan Beamon (2004) that are performance measure model by involving the four measurement variables: delivery to commit date, order fulfillment leadtime, response time, and make time. The result of the data analysis describes that the actual performance of the four variables still in below the target. Therefore, it is suggested to conduct a restructurization to redesign the ONS system itself. Proposal of designing based on Beamon theory to develop operation improvement. The processing time during the packages stay in ABC's branch of Solo needs a very long duration passing by the definite target, so it is recommended: 1). to eliminate the uneffective process, 2). to merge the processes that are possible to be handled together, 3). to use better facility to shorten the length of the process, and 4). to apply a new documentation system.

Abstract

A company or business entity is required to perform the activities effectively and efficiently. The economic condition of the enterprise develop rapidly between companies or business entities get stiff competition. In the face of competition, companies need planning and cost control, especially in distribution transport logistics. One way that can do is to reduce operating costs, especially in terms of logistic distribution, logistic distribution costs which are rarely considered. The study was conducted at the home industry manufacturing know Sentra Industry Tahu, Mojosongo RW 03, Surakarta. The problem that occurs is unoptimalization product distribution that due to limited fleet which causes inefficient distribution activities in terms of time and cost. Of the issues raised, there are vehicles used alternative is to use motorcycles and cars, both for new vehicles and used vehicles. To find an alternative use can be done by calculating the net persent value and payback period. Based on the calculation of NPV and PBP is known that the chosen alternative is to increase the company's investment in the form of the addition of used cars as a consistent supporter of logistic distribution with the NPV was Rp. 426.548.000,00 and the return on investment amounted was for 3 months 17 days

Abstract

CV. Kembar Jaya is a metal casting manufacturing company which applies Make to Order (MTO) system. It,s characteristic of scheduling is dynamic batch on flow shop production system. This scheduling method has risen the tardiness of order completion and high level of pouring scrap. To solve this problem, a rescheduling procedure which able to increase the system’s performance is needed. To increase the system performance, a development of batch dynamic scheduling algorithm has been done to minimize the mean tardiness and total pouring scrap. The algorithm consists of setting molding area initialization and five sub algorithms. Sub algorithm of sorting order and determinating batch size will sort and breakdown the order into batches. Sub algorithm of molding area repairing will determine molding area allocation for batches. To prevent the drop temperature, sub algorithm of determination pouring time will identify the pouring temperature for batches. Sub algorithm of batch scheduling will schedule batch to work station. Then sub algorithm of rescheduling will accommodate the dynamic environment when order was inserted. Mean tardiness from the scheduling algorithm application is 7.39 hours or minimize mean tardiness until 65.72 %, from the current scheduling algorithm. Application of the scheduling algorithm can reduce total pouring scrap into 0 kg or 100 %.

Abstract

In Surakarta and its surroundings (Solo Raya), there exists more than 400 Small-Medium Enterprises (SMEs) that produce finished products of rattan. Due to the high procurement cost as total operational cost of raw rattan distribution network from the sources, e.g. Borneo and Celebes to the rattan industries, the competitiveness of their products is lower than products from other countries. Therefore, to overcome the problem, those costs should be reduced for example by aggregating the demand of rattan industries. This police needs to be supported by the warehouse for storing and distributing raw rattan. Hence, this research aims to develop a facility location-allocation model so that total supply chain costs, including raw rattan procurement costs as well as facilities opening and closing costs can be minimized. The location-allocation model will be presented in a mixed integer non-linear programming model and solved using MS-Excel Solver. The results are number and location of the warehouse along with the raw rattan allocation in the warehouse to ensure raw rattan supply for rattan industries.

Abstract

This paper develops a vehicle routing problem (VRP) model for determining the routes in urea fertilizer distribution from a depot to retailers. The distribution is done in work days which uses trucks, each truck can serve more than one route (multiple trips), and each retailer has a time window. The vehicle routing model is built in a mixed integer linear programming (MILP) and the objective function is minimizing total transportation cost. The distances from the distributor to retailers and inter-retailers do not use Euclidian approach but the road network on a digital map in order to make the route solution is more realistic. Historical distribution data was used to test the model. The result shows that the model can minimize the cost about 2.28% which is compared to the original routes.

Abstract

In general, small-scale vegetable farmers experience problems in improving the safety and quality of vegetables for supplying high-class consumers in modern retailers. Farmer Group and/or Cooperative (FGC) should be able to assist its members to meet the relevant provisions of modern retail on product specifications, delivery terms, and internal business requirements. This study proposed an agri-food supply chain (ASC) model that involves the corporate social responsibility (CSR) activities to enhance the business skills of the FGC as supplier of modern retailer. Multi-objective optimization programming is developed to determine the amount and timing of supply, level of farmers training skills, quality improvement target, and the CSR total cost. The results show that the proposed model can be used to determine the priority of programs in order to empower farmers' groups as modern retail suppliers.
