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

In this paper, we consider a joint economic lot size (JELS) model consisting of single vendor single buyerwith single product. We intend to study the impact of defective items and controllable production rate onthe model. The demand in buyer side is assumed to be stochastic. The delivery of lot from vendor to buyer is conducted under equal size shipment and the lead time is assumed to be constant. The defective items founded by the inspector in buyer side are carried in buyerâ€™s storage until the next shipment and will be returned to the vendor. The goal of the proposed model is to determine optimal delivery frequency, review period and production rate by minimizing the joint total cost. A sensitivity analysis is performed to show the impact of the changes of the decision variables on modelâ€™s behavior. The result from the sensitivity analysis shows that the joint total cost is sensitive to the changes of defect rate, demand uncertainty and demand rate.Â

There are three aspects of competitive strategy that can be applied by manufacturing companies: quality, cost, anddelivery time. Actually, it is hard to produce high quality poducts in low manufacturing cost and on time delivery. Hence, a process selection is needed to integrated the three aspects above in order to meet a customer requirement. This research develops a process selection model to minimize manufacturing cost, quality loss cost, and lateness cost considering component spesification, delivery time, production capacity, and customer order. A numerical example is given to show the application of the model using an assembly product that consists of three components. Three machines are used to produce all of the components. Each machine has different characteristic in manufacturing cost, tolerances, and processing time. Total cost that used to produce 100 unit assembly product is Rp5.390.970,00.

Mayoritas masyarakat di Pulau Jawa menggunakan genteng sebagai atap bangunan. Genteng yang beredar di pasar, sebagian besar dari IKM yang belum memenuhi standar kualitas sesuai SNI 03-2095-1998. Untuk meningkatkan kualitas genteng supaya memenuhi SNI 03-2095-1998 dilakukan pendekatan eksperimen proses pembuatan genteng. Ekperimen dilakukan pada komposisi bahan baku pembuat genteng. Bahan baku utama adalah tanah liat, sedangkan bahan baku lain adalah serbuk kaca dan abu sisa pembakaran kayu. Pemanfaatan bahan ini sebagai usaha untuk memanfaatkan limbah lingkungan. Strategi eksperimen dilaksanakan untuk mendapat komposisi bahan yang menghasilkan kualitas genteng yang sesuai SNI 03-2095-1998. Eksperimen dilaksanakan dengan melibatkan pembuat genteng, sehingga hasil optimal dapat diterapkan dalam industri pembuatan genteng. Kualitas yang diukur adalah kekuatan tekan dan penyerapan air. Hasil eksperimen menunjukan bahwa kekuatan tekan adalah 371,72 Kgf dan penyerapan air adalah 0,16%. Hasil optimal ini sudah memenuhi syarat kualitas genteng menurut SNI 03-2095-1998.

Model Penentuan Nilai Target Functional Requirement Berbasis Utilitas Cucuk Nur Rosyidi

In a product design and development process, a designer faces a problem to decide functional requirement (FR) target values. That decision is made under a risk since it is conducted in the early design phase using incomplete information. Utility function can be used to reflect the decision maker attitude towards the risk in making such decision. In this research, we develop a utility-based model to determine FR target values using quadratic utility function and information from Quality Function Deployment (QFD). A pencil design is used as a numerical example using quadratic utility function for each FR. The model can be applied for balancing customer and designer interest in determining FR target values.

Intense competition among companies encourages them to provide the best quality of products in competitive price. It is important for company to manage supply chain properly in order to achieve that. Selecting the best reliable supplier is the key to reduce purchasing cost, increase customer satisfaction and improve the competitive ability. In this study, we develop an order allocation model in multi echelon environment which includes supplier, manufacturer, and retailer. We consider transportation alternatives for the shipment from supplier to manufacturer and also the shipment from manufacturer to retailer. This model allows lateral transshipment between retailers. A Mixed Integer Linear Programming (MILP) is used to model the system. Sensitivity analysis is conducted at the end of the research. The result shows that the retailer demand, lead time, material variable price are sensitive to the objective function while the transportation costs from supplier to manufacturer, from manufacturer to retailers, and between retailers are not sensitive to the objective function. Retailer demand parameter is also sensitive to all decision variables. The transportation cost from supplier to manufacturer, material prices, and lead time are sensitive to the order allocation from manufacturer to supplier, while transportation cost from manufacturer to retailers and transportation cost between retailers are sensitive to the allocation of product sent from the manufacturer to retailers and the allocation of product sent between retailers.

In a manufacturing company, manufacturing costs, or component prices, and tolerance will affect the price and the quality of a product. Companies must produce high-quality products with low manufacturing costs in order to keep their products competitive in the market; however, it is difficult to produce a high-quality product with a low manufacturing cost. Companies have difficulties in determining the components to be produced using their own manufacturing facilities (make) or outsourced to their suppliers (buy). Hence, a make or buy analysis is needed to minimize the manufacturing costs and quality loss and to determine the optimum alternative regarding make or buy decisions. This paper discusses an optimization model of a make or buy analysis for a manufacturing company in order to minimize the manufacturing costs and the quality loss in terms of manufacturer and customer quality loss. A numerical example is provided to show the application of the model using a simple assembly product consisting of three components. There are two machines that can be used to produce the components and three alternatives of suppliers to fulfill the order. Each machine and supplier have different characteristics in terms of manufacturing costs and its tolerance.

UD Mella Kreasi merupakan Industri Kecil Menengah (IKM) Furniture dan Handycraft, berlokasi di Serenan Klaten. Pihak manajemen UD Mella kreasi memaparkan masalah berkaitan dengan pengelolaan persediaan bahan baku, yaitu sistem pengelolaan yang kurang terstruktur, pencatatan manual yang rawan hilang, hingga beban kerja karyawan di UD Mella Kreasi yang terindikasi kurang seimbang di area produksi dan gudang. Digitalisasi sistem persediaan berpotensi menjadi alternatif solusi untuk mendukung UD Mella Kreasi. Sistem persediaan yang akan diimplementasikan di UD Mella Kreasi adalah aplikasi AirTable cloud, yaitu software open-source yang potensial dipergunakan sebagai sistem pencatatan persediaan berbasis cloud computing. Aplikasi ini tidak berbayar, tidak memerlukan investasi hardware memori, dan penggunaannya cukup sederhana sehingga sumber daya manusia di UD Mella Kreasi cukup mampu mengoperasionalkannya. Implementasi diawali dengan sosialisasi, pelatihan dan pendampingan. Setelah kurang lebih tiga bulan diimplementasikan, proses di gudang bahan baku dapat lebih teratasi oleh administrasi UD Mella Kreasi, sehingga lebih terstruktur, dan karyawan produksi tidak perlu lagi diperbantukan di gudang persediaan untuk menata, mencari, dan menstrukturkan kayu, rotan, dan bahan baku furniture yang lain.
