Abstract

In Indonesia, there are three industrial sectors with the largest number of Small Medium Enterprises (SMEs) from 2010 to 2014: food, clothing, and wood. Klastik Footwear is one of the SMEs in Indonesia that focuses on the footwear industry, especially women's shoes. Klastik Footwear brings classic and ethnic themes to its products. In order to be well received by the market, Klastik Footwear wants to identify potential consumer groups formed from market segmentation and assess the preferences of each group on Klastik Footwear products. In this study, the choice based conjoint analysis method is used to determine potential consumer preferences for Klastik Footwear products. From the results of the conjoint analysis, the importance and part-worth level of each attribute will be known. Next, a cluster and market simulator analysis is performed to see the profile of the formed segments. The results showed that there are 3 groups of potential consumers. After conducting market simulation on the three groups, it is predicted that the most ordered Klastik Footwear products by consumers are Galuh, Ara, Srikandi, and Gendhis 2 (in group 1); Brastagi, Telaga, and Gendhis 2 (in group 2); and Rinjani, Galuh, and Soko (in group 3).

Abstract

Model lokasi spasial adalah model dalam bidang ekonomi yang digunakan untuk menggambarkan kompetisi monopolistik di mana pelanggan memiliki preferensi terhadap merek sebuah produk dan lokasi tokonya. Model ini pertama kali diusulkan pada tahun 1929 yang umumnya disebut sebagai Hotelling’s linear city model. Model tersebut memberikan kontribusi yang sangat besar di bidang ekonomi dan teori permainan (Game Theory). Banyak penelitian terkini yang dikembangkan dari model linear city tersebut. Aplikasinya sendiri bisa dalam berbagai bidang mulai dari facility location hingga pricing decision. Kasus nyatanya di Indonesia adalah persaingan antara Alfamart dan Indomaret. Hal ini dapat terlihat dari lokasi toko dan harga mereka yang sangat bersaing. Untuk menarik lebih banyak pelanggan, selain berperang dari segi harga dan  lokasi toko, Alfamart dan Indomaret juga berperang dalam segi diskon (rebate war). Akan tetapi, penelitian mengenai Hotelling’s linear city model yang memepertimbangkan rebate war ini belum banyak dilakukan. Oleh sebab itu, pada penelitian ini kami mengusulkan sebukah model Hotelling’s linear city model dengan melibatkan factor diskon (rebate). Pada penelitian ini, kami mengusulkan sebuah persemaan untuk menghitung nilai diskon terbaik. Penelitian ini juga disetai dengan beberapa percobaan numerik, insight serta diskusi dari model yang diusulkan.

Abstract

In accordance with Hottelling's Law, strategic location is a significant factor to ensure the success of a business, thus two businesses which sell the same product tend to choose a closed location. The real practice of this concept is seen in the competition of two big retailers which often open their shop nearby. However, in such competition, the location factor is merely not sufficient. It is necessary to consider other factors such as price and rebate or discount types given to their customers. This paper, particularly, aims to see the customers' preferences towards given attributes i.e. price, location, and discount types. The data is collected bymeans of a survey with non-probability sampling that is judgmental sampling. The respondents are people reside in Surabaya, Sidoarjo, and nearby whose age between 15-45 years and having various profession. The data is then processed with conjoint analysis by which is used as a basisto reconstruct a demand model considering the customer's preferences. The result shows that the attribute which is most considerable by respondents is the discount types, herein is a bundling product that comprises various products. This attribute has a preference level at 54.53%. The second prioritized attribute is the retailer location with a preference level at 24.28%. This means that a closer retailer is the most preferable by the respondent. Meanwhile, price is the last attribute considered by the respondent in choosing the retailer with a preference level at 21.28%. Thus, a respondent tends to pick a cheaper product after considering its discount type and the distance of retailer.
