Abstract

Yulis’s home industry is one of the Small and Medium Bussiness (UKM) on Palembang city. Yulis’s home industry produces bolu kukus, kue lapis, kue pare, kumbu kacang, srikaya, and wajik. Most of cakes that will be produced by Yuli is still based on the cake sale on the last day, so that the profit is still not optimal condition. This research aims to create preemptive priority additive approach to Fuzzy Goal Programming Probabilistic (PFGP) model with Pareto distribution for maximize profits, minimize the production of perishable cake, and maximize best sellers cake. The results are obtained maximum profit is Rp. 8.488.569 on a week , the amount of perishable cake is 1,295 pieces on a week, and optimal production for best seller cake as much as 8,489 pieces on a week.

Abstract

The aim of this research is to know factors having an influence by significant to Entrepreneurship Intention of students in Faculty of Mathematics and Natural Sciences of Sriwijaya University. There used a Structural Equation Models (SEM) analysis method, because variables in this research in the form of laten variable and causal relationship between a set of variables nor modestly, there is direct and indirectly relationship. The result show that family environment give a part important in forming Entrepreneurship intention student, and so Personal attitude give biggest direct influence to Entrepreneurship Intention of student equal to 0,52 with t-test statistical value equal to 6,82.

Abstract

Waste management in the district Kertapati done by the private sector and government. The authorities responsible for waste management is Palembang City Sanitation Department (DKKP). Waste is transported from the area TPS (Transit Depo) to landfill Sukawinatan use two types of vehicles, namely dump trucks and armroll. Analyzed the optimal number of vehicles ritase waste carrier with the highest amount of waste as a goal. The total time of transport, the maximum capacity of conveyance and the maximum amount of waste that must be transported as an integer linear programming constraints. Completion of linear models using methods Branch and Bound. Volume of waste in Lambung 87 is 7630 kg, the optimal use of dumb truck with 2 ritase carriage. Volume of waste in the Lambung 42 as much as 8850 kg, optimal use armroll with 3 ritase carriage. The amount of waste in the Lambung 69 as much as 7770 kg, more optimal use of dumb truck with 2 ritase carriage.

Abstract

Penelitian ini bertujuan untuk menentukan jumlah optimal kendaraan pengangkut sampah menggunakan model goal programming (GP) dengan pendekatan fuzzy. Jumlah minimum sisa sampah yang tidak terangkut dan muatan kosong kendaraan sebagai goal. Jumlah sampah yang harus diangkut, jumlah ketersediaan kendaraan pengangkut, dan jumlah area layanan dinyatakan dalam bentuk Triangular Fuzzy Number (TFN) dan merupakan kendala pada model fuzzy goal programming (FGP). Model FGP diubah ke bentuk deterministik menggunakan teknik program fuzzy. Dipertimbangkan dua jenis kendaraaan yaitu dumb truck dan armroll. Diberikan contoh perhitungan untuk kecamatan Kalidoni kota Palembang. TFN jumlah sampah adalah (58100, 58150, 58300), TFN jumlah dump truck (190,190,193), TFN jumlah armroll (21,21,22), TFN jumlah minimal wilayah layanan (4,5,5). Diperoleh solusi optimal dengan derajat keanggotaan 0,8 untuk mengangkut sampah sebanyak 58150 kg diperlukan kendaraan jenis dump truck sebanyak 1 kendaraan dan jenis armroll sebanyak 18 kendaraan. Terdapat sisa sampah yang tidak terangkut sebanyak 140 kg.

Abstract

Waste management in the district Kertapati done by the private sector and government. The authorities responsible for waste management is Palembang City Sanitation Department (DKKP). Waste is transported from the area TPS (Transit Depo) to landfill Sukawinatan use two types of vehicles, namely dump trucks and armroll. Analyzed optimality waste carrier vehicles with a total transport time constraints, the maximum capacity of conveyance and the maximum amount of waste that must be transported using integer programming binary 0 and 1. Integer programming binary 0 and 1 problem solved by the Branch and Bound Method. The maximum amount of waste that must be transported to the Lambung 87 is 7330 kg, Lambung 42 as much as 8850 kg and the Lambung 69 as much as 7770 kg. Dump truck and armroll are  vehicles optimized for use on Lambung 42, 87 and 69.
