Abstract

Penentuan sister city berdasarkan indikator pengeluaran pola konsumsi masyarakat dapat memberikan gambaran yang akurat tentang karakteristik kesamaan ekonomi antar wilayah. Penelitian ini memanfaatkan data hasil survei sosial ekonomi nasional untuk memilih sister city bagi Kabupaten/Kota tanpa Survei Biaya Hidup (SBH) di Jawa Barat. Kemiripan antar wilayah didasarkan pada tujuh area pengeluaran konsumsi, yaitu kelompok makanan, perumahan dan fasilitas rumah tangga, aneka barang dan jasa, sandang, barang tahan lama, barang tidak tahan lama dan keperluan pesta/upacara. Ukuran kedekatan yang digunakan adalah jarak Euclidean dengan standardisasi data berbasis peringkat fraksional terkoreksi. Pendekatan metode tersebut menghasilkan delapan sister city bagi tujuh belas Kabupaten/Kota non-SBH di Jawa Barat. Kabupaten Bandung sister city bagi Kabupaten Sukabumi, Tasikmalaya, dan Bandung Barat. Kabupaten Cianjur, Garut, Kuningan, Cirebon dan Kota Banjar menempatkan Kabupaten Majalengka sebagai sister city. Kabupaten Subang, Bogor, Kota Bandung dan Depok, secara berurutan sister city bagi Kabupaten Indramayu, Bekasi, Kota Sumedang dan Cimahi. Kota Cirebon sister city bagi Kabupaten Bogor dan Karawang, dan Kota Tasikmalaya sister city bagi Kabupaten Ciamis, Purwakarta, dan Pangandaran

Abstract

Skincare products are beauty care products used to prevent, improve, and treat skin problems such as acne, acne scars, blemishes, or to brighten the skin, treat dark skin, delay aging, or brighten the skin. The purpose of this study was to determine consumer preferences for purchasing skincare products based on three main characteristics, namely product origin (local or international), product benefits (brightening, moisturizing, anti-aging), and price. Data were analyzed using a conjoint analysis approach to determine consumer preferences in choosing skincare products. The results of the analysis showed that the products most preferred by consumers were local products that were useful for brightening the skin, with prices below fifty thousand. The majority of respondents were women who lived on the island of Java, with an average age of 23 years 9 months and were students. They purchased skincare products once every one to two months. Based on the model obtained, it shows that the benefits and origin of the product are more considered than the price.
