Judul: Analisis Preferensi Konsumen dan Tingkat Kepuasan Terhadap Atribut Sayuran Organik
Abstrak: Sayuran organik merupakan sayuran yang dihasilkan dari proses bercocok tanam secara alami yang mengandalkan unsur-unsur alam sehingga produk yang dihasilkan tidak mengandung bahan kimia berbahaya. Sampai sejauh ini, umumnya sayuran organik lebih mudah ditemukan di kota-kota besar di Indonesia dan dipasarkan di pasar modern atau pasar swalayan tertentu. Hal tersebut disebabkan karena harga yang ditawarkan oleh produsen kepada konsumen untuk bisa mendapatkan sayuran organik relatif lebih mahal dari pada sayuran anorganik. Penelitian ini bertujuan untuk menganalisis karakteristik konsumen sayuran organik, preferensi konsumen sayuran organik, tingkat kepuasan konsumen terhadap atribut sayuran organik dan ketertarikan antara ketiganya. Metode pengumpulan data yang digunakan berupa teknik purposive sampling melalui penyebaran kuesioner kepada 140 responden. Sedangkan, metode pengolahan data yang digunakan dalam penelitian ini yaitu analisis deskriptif, analisis konjoin, Importance Performance Analysis (IPA), Customer Satisfaction Index (CSI) dan Chi Square. Hasil perhitungan preferensi konsumen dalam penelitian ini menunjukkan bahwa, kemasan merupakan indikator yang memiliki tingkat kepentingan tertinggi sebesar 28,99 persen. Berdasarkan hasil IPA, terdapat dua atribut yang memiliki prioritas utama untuk diperbaiki kinerjanya oleh Top Buah Segar Cibubur yaitu harga sayuran organik terjangkau dan potongan harga sayuran organik. Kemudian berdasarkan hasil perhitungan CSI didapatkan nilai sebesar 76,67 persen, dimana dari hasil perhitungan tersebut konsumen dinyatakan puas terhadap kinerja Top Buah Segar Cibubur. Uji Chi Square menunjukkan bahwa pada hasil karakteristik konsumen dengan preferensi konsumen didapatkan bahwa indikator jenis kelamin, usia, pekerjaan dan penerimaan memiliki keterkaitan dengan indikator harga pada preferensi, kemudian indikator pekerjaan memiliki keterkaitan dengan indikator label. Pada hasil karakteristik konsumen dengan kepuasan konsumen didapatkan bahwa status pernikahan memiliki keterkaitan dengan harga pada kepuasan, kemudian untuk pekerjaan memiliki keterkaitan dengan tempat. Pada hasil preferensi konsumen yang meliputi jenis sayuran, harga pada preferensi, kemasan dan label tidak memiliki keterkaitan dengan tingkat kepuasan konsumen yang meliputi produk, harga pada kepuasan, tempat dan promosi., Organic vegetables are vegetables produced by natural farming which depend on the elements so that products produced are devoid of chemical elements. Thus far, organic vegetables are easier to locate in major cities in Indonesia and mainly marketed in modern markets or supermarkets. It is caused by the price offered by producer to consumer to be able to get organik vegetables is relatively higher than inorganik vegetables. The study aims to analyze the characteristics of the consumer of organic vegetables, the consumer preferences for organic vegetables, the level of consumer satisfaction towards organic vegetables, and the correlation between those three variables. The data have been collected using purposive sampling technique through distribution of questionnaire to 140 respondents. Meanwhile, the data processing methods used in this research include descriptive analysis, conjoint analysis, Importance Performance Analysis (IPA), Customer Satisfaction Index (CSI), and chi square. Consumer preference calculations in this study indicate that packaging is an indicator with the highest levels of interest at 28,99 percent. According to IPA results, there are two attributes that have the highest priority for performance improvement by Top Buah Segar Cibubur which is the price of affordable organik vegetables and discounts on organic vegetables. According to CSI, the calculation results is 76,67 percent, which means the consumer was content with the performance

Judul: Approximation of the Median of Poisson Distribution Using the Relation of Poisson-Gamma Distribution
Abstrak: A major drawback of median is that median cannot usually be defined in closed form, even in the cases where their distribution functions are known. This study gives an approximation of the closed form for the median of the Poisson distribution by using the relation of Poisson-Gamma distribution. The approximation uses elementary techniques based on the monotonicity of certain sequences involving tail probabilities of the Poisson distribution and the Central Limit Theorem. Furthermore, a closed form expression for the mean absolute deviation 􀜧|􀜰􀰒 􀵆 􀜯􀝁􀝀􁈺􀜰􀰒􁈻| is also studied. The median is relevant because of the fact that it minimizes the mean absolute deviation of a Poisson random variable (􀜰􀰒􁈻 by considering median as central tendency.
