Abstract

Competition, which becomes more widespread, complex, and intense, drives companies to must be able to see the various opportunities that exist and to identify strategies for creating customer satisfaction. As an example of a company must be able to produce products with good quality, reasonable price, facilities, and companies are able to create a positive image in the eyes of consumers. This strategy is quite important in facing the competitive level of competition with rival firms. This research is aimed to analysis simultaneously or partially positive effect of the facilities, prices and corporate image on customer satisfaction, as well as analyzing the most dominant variable in effecting bookstore customer satisfaction. Data used in this research are primary data from Tmbookstore customer in Cianjur city, West Java Indonesia, which were collected from respondents using valid and reliable questionnaire. A total of 100 respondents were selected from Tmbookstore visitors by accidental sampling. Data were analyzed using multiple regression analysis. Results of the research indicate that product, price, location, and simultaneously affect to bookstore consumer satisfaction. Partially, only two of the three variables that affect bookstore consumer satisfaction namely price and company image. Image of the company is the most a dominant impact on bookstore customer satisfaction.

Abstract

Abstract: Linear programming is mathematical method to resolve problems of allocating limited resources to achieve destination like to maximize profits and minimize costs. One of the methods to resolve linear programming problems is simplex method maximum. This research takes into the production of Flat Panel Monitor of four sizes and will point more products that contribute the main function of profit. Methodology for the optimization of the profit of LCDs manufacturing company, the linear programming and sensitivity analysis methods were applied. The four constraints of the LCDs production planning are (1) acquire of line space for production, (2) the assembly of products, (3) quality control and assurance hours (4) and packaging of material. Results in all three scenarios that the total profit is optimum and increases from scenario 1 to scenario 3. The difference between the profit of scenario 1 and scenario 2 is $ 257625, and gap between scenario 2 and scenario 3 is $ 171750. It can be concluded that the three scenarios for the production of the LCDs present the varying consequence of the maximum profit for the company. However, the third scenario is the most optimal solution for the maximization of the objective function. Keywords: Linear Programming, Simplex Method, Production Planning, Profit Optimization

Abstract

Besarnya ongkos transportasi dapat menurunkan maksimasi profit sehingga biaya distribusi perlu ditekan. Salah satu cara untuk menekan biaya transportasi tersebut adalah dengan menggunakan model masalah transportasi dengan mencari solusi layak awal. Salah satu metode untuk mencari solusi layak awal adalah dengan Best Candidates Method (BCM). Pada BCM, kandidat dipilih dengan memilih dua unit ongkos terkecil untuk tiap-tiap baris, kemudian kandidat-kandidat tersebut disusun sehingga membentuk kombinasi-kombinasi yang menghasilkan total biaya terkecil. Best Candidate Method menghasilkan solusi layak awal dengan total ongkos terkecil dengan cara membandingkan total ongkos antara kombinasi yang satu dengan kombinasi lainnya. Pada contoh kasus yang dipelajari, contoh kasus pertama yaitu distribusi pupuk berbentuk model masalah transportasi tidak seimbang dengan total supply sebesar 51 ton pupuk dan demand sebesar 52 ton pupuk. Hasil akhir yang diperoleh yaitu solusi layak awal dengan total cost terkecil adalah $1005. Sedangkan contoh kasus kedua yaitu distribusi air minum berbentuk masalah transportasi seimbang dengan total supply sama dengan total demand yaitu sebesar 12 kilo liter dengan hasil akhir yang diperoleh yaitu solusi layak awal dengan total cost terkecil adalah sebesar $23.Kata kunci : Best Candidates Method, Solusi Layak Awal, Masalah Transportasi, Model Masalah Transportasi tidak Seimbang, Model Masalah Transportasi Seimbang.

Abstract

Pada penelitian ini akan disajikan model untuk memecahkan masalah transportasi satu kendaraan dan masalah transportasi dua kendaraan. Pada model ini biaya transportasi bisa bervariasi disebabkan oleh kapasitas kendaraan dari masing-masing masalah serta kuantitas dari jenis transportasi. Algoritma untuk menentukan solusi layak awal akan membantu dalam pencarian solusi layak awal dari kedua masalah tersebut, sehingga dapat diketahui mana biaya transportasi yang lebih minimum. Dimulai dari mendiagnosis masalah, membuat matriks transportasi, mengalokasikan barang dari sumber ke tujuan menggunakan metode sudut barat laut, mencari biaya unit transportasi, sampai akhirnya menemukan solusi layak awal. Perbandingan akan menunjukan berapa jenis kendaraan yang lebih efektif untuk digunakan dalam pendistribusian barang. Dari melihat total biaya transportasi dari kedua contoh kasus diketahui bahwa dengan metode transportasi dua kendaraan total biaya transportasi adalah 92 satuan biaya sedangkan dengan metode transportasi satu kendaraan total biaya trasnportasi adalah 641 satuan biaya untuk kendaraan jenis kesatu dan 1255 satuan biaya untuk kendaraan jenis kedua. Sehingga penentuan biaya transportasi dengan metode transportasi dua kendaraan jauh lebih kecil dibandingkan dengan menggunakan metode transportasi satu kendaraan.

Abstract

HIV (Human Immunodeficiency Virus) adalah virus penyebab penyakit AIDS (Acquired Immunodeficiency Syndrome) yang ditemukan di bali pada tahun 1987, kasus HIV dan AIDS menyebar hampir di seluruh provinsi Indonesia dan mengalami peningkatan jumlah penderita setiap tahunnya. Pada paper ini dibahas model matematika untuk penyebaran penyakit HIV-AIDS [1]. Model merupakan sistem dinamik non linier tiga dimensi yang menggambarkan Interaksi tiga populasi yaitu Susceptible, Infected, dan AIDS Cases. Analisis kestabilan dari titik kesetimbangan endemik menggunakan metode Kriteria Routh Hurwitz. Bilangan reproduksi dasar digunakan untuk menganalisis keendemikan penyakit HIV-AIDS yang diperoleh menggunakan next generation matrix [2]. Hasil analisis memberikan informasi bahwa semakin besar nilai bilangan reproduksi dasar maka penyebaran penyakit HIV-AIDS di dalam suatu populasi akan semakin cepat dan dalam waktu yang lama penyakit tersebut akan tetap ada. Berdasarkan analisis sensitivitas diketahui parameter-parameter yang berpengaruh terhadap bilangan reproduksi dasar yaitu tingkat kontak Susceptible dengan Infected, peluang sukses terjadinya transmisi virus HIV dari Infected ke Susceptible, tingkat kontak Susceptible dengan AIDS Cases, peluang sukses terjadinya transmisi virus HIV dari AIDS Cases ke Susceptible, tingkat kematian yang disebabkan oleh penyakit AIDS, dan tingkat penjangkitan virus HIV.
