Abstract

The aim of this research is to analyze the probability of customer to switch from one brand of motorcycle to another. In this research, Markov Chains is used to analyze the switching probability. This research begins with identification of the initial marketing variables. In order to analyze brand loyalty with Markov Chains, three types of motorcycle from economic under-bone class (110-115cc) have been selected namely Absolute Revo, Vega ZR, Smash Titan and other types outside the class are used as comparison. Mann Whitney U Test is used to examine whether there are differences on marketing variables between men and women when selecting their motorcycle. The result of this research shows that the most loyal customer is in the type of motorcycle outside the economic underbone class. The most affecting variables that determine the existing motorcycle preferences is the availability of spareparts and the number of authorized service center for Absolute Revo, comfortable while driving for Vega ZR, and reliability motorcycle engine for Smash Titan and other types. The most variables that determine switching to another type of motorcycle is the product innovation. The results of Mann Whitney U test show that there are significant differences in marketing variables between male and female in existing motorcycle preferences which are motorcycle design and engine specifications.

Abstract

In general, planning supply use the information from combination varying capacity and inventory to plan the aggregate rates of production by time period for groups of product. This research objective is PT. Tiga Pilar Sejahtera’s (TPS) that produces wafersticks. In the company sometimes occured the wafersticks product can be not fulfilled. This is happened because waferstick inventory unstable. This causes problems that PT. Tiga Pilar Sejahtera (TPS) was less capable to fulfill the market’s demands. To solve this PT TPS should be managing the working hours, workforces, production capacity and finished goods inventory, they are called aggregate planning. This research are determine safety stocks, planning supply and material inventory planning.Managing supply of waferstick product is started by forecast the demand. The forecast result is used to estimate safety stock of waferstick. Then the forecasting result and safety stock become of input Integer linier programming model to determine aggregate planning. The aggregate planning is used to find optomal lot size of waferstick raw material. Then lot sizing become input Planned Order Receipt in the Material Planning Requirements (MRP). Forecast method used to forecast the demand is decomposition, this method is he best method find estimation demand because it have more less MAD than the other. The determination of the safety stock is actually more accurate with the 90% by Romy & Yuli waferstick safety inventory is 1106 cartons and 2364 cartons for Pio. From aggregate planning there is back order in 13 th is 11 cartons. The planning cost for Romy & Yuli waferstick Rp 625.670.902,33 and Cost for Pio waferstick Rp 1.462.296.180,00. Waferstick material planning by optimal lot size between 695 kilograms up to 8487 kilograms by waferstick materials cost is Rp 6.315.520,00.

Abstract

Performance measurement is important to business organization both manufacturing or service industry, and education. Performance measurement considers all activities and satisfies stakeholder’s requirements. The aim of his research is to design performance measurement in a Department in X University using Integrated Performance Measurement Systems (IPMS) method. IPMS is a performance measurement method that considers stakeholder’s requirements and measure performance integrally. IPMS method generates Key Performance Indicators (KPI) from stakeholder’s requirements by four steps, that are; identification of stakeholder’s requirements, development of external monitor, objectives establishment, and identification of KPs. Each of KPI has difference significance to performancemeasurement system. The significance of each KPI is counted by Analytical Hierarchy Process (AHP). This research results 7 performance measurement perspectives that consist of 15 objectives. The objectives can be measured by 57 KPI (consist of 43 main KPI and 24 sub KPI)

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.
