Metode simpleks primal dengan variabel dibatasi

ABSTRAK Dalam kejadian khusus, masalah program linier biasanya menggunakan variabel yang dibatasi. Variabel x. dibatasi dari bawah dengan Z. dan dari atas dengan u.. Jika vektor-vektor batas bawah dan batas atas masing-masing ditunjukkan dengan I dan u, maka masalah program linier dikatakan program linier dengan variabel dibatasi. Jika diselesaikan dengan eara biasa dengan menambahkan variabel slack maka persamaan kendala bertambah dari m menjadi m4-2n dan banyaknya variabel bertambah Bari n menjadi 3n. Dalam metode simpleks pertidaksamaan 15x5u dipecahkan secara iniplisit sehingga pada awalnya layak untuk diselesaikan menggunakan metode simpleks (biasa). Dalam pembahasiiifnIideSimpleks dengan variabel dibatasi digunakan untuk memecahkan masalah program linier melalui penyelesaian primalnya

A Sustainable Supply Chain Model of Relationship Between Wood Supplier and Furniture Industry in Indonesia

Wooden furniture industry is an important industry sector in Indonesia, because many people\u27s welfare relyon this industry sector and the industry has a big social and environmental impacts. Many wooden furnitureindustries in Indonesia, especially in Central Java Province face problems related to the sustainability. The relationbetween wood suppliers and furniture industry is studied in this paper. A sustainable supply chain management (s-SCM) model is proposed as an approach for solutions for the problems. The approach is chosen due to the characteristics of the problems that related to economic, social, and environmental problems. This aim of this paper is to determine how much supply teak wood must be provided by PP to satisfy furniture industry demand, how much production capacity that must be increased and how large forest area that must be planted in order to achieve environmental and social goals without sacrificing economical goals much. Goal programming (GP) is chosen for solving the problems, because the goals are to maximize the total benefit,minimize the total loss and anticipate the conflicts between goals. Numerical trial based on observation in teak wooden furniture industry in Central Java was used to illustrate our findings. Using pareto efficient principle, the model can satisfy all goals that need to be achieved. Numerical results can be used by decision makers in teak wood industry to analyze the trade-off among several set of alternative solutions

Designing Information System To Support Business Process Improvement In A Small-Mid Size Bottled Drinking Water Industry

Due to inefficiencies of the business processes in small-mid size of bottled drinking water industries, it is necessary to improve them. The improvements are carried out in business processes of production, warehouse, delivery, marketing, and finance departments. The main causes of the inefficiencies are the inefficiencies of the business process itself and that the business processes of those departments were not integrated. This paper is concerned with designing information system to support for the integration of those departments. First, we mapped the business process of each department using flow diagram. Then analyze the inefficiencies of each department. Next, we redesign the business processes and standardize them. The next step is integrating the business processes by designing the information system. We design the information system modular. The modules are marketing module, production module, logistic module and finance module. Data Flow Diagram (DFD) is used to model the system. Relational database management system (RDBMS) is used to design the database. User interfaces are built to ease in using the program application. The outputs of the information system are reports and documents in monitor screen view and in printing. The validation showed that the information system designed can support the business process improvements. Keywords: business process improvement, integration, information system, small-mid size of bottled drinking water industr

Diversity analysis of mangosteen (Garcinia mangostana) irradiated by gamma-ray based on morphological and anatomical characteristics

Tujuan penelitian ini adalah meningkatkan keragaman genetik manggis (Garcinia mangostana L.) yang diiradiasi dengan sinar gamma dosis 0 Gy, 20 Gy, 25 Gy, 30 Gy, 35 Gy dan 40 Gy. Bahan tanaman yang digunakan adalah biji yang dikumpulkan dari Kampung Cegal, Desa Karacak, Kecamatan Leuwiliang, Kabupaten Bogor, Jawa Barat. Data dihasilkan dari karakteristik morfologi dan anatomi. Hasil penelitian menunjukkan bahwa peningkatan dosis sinar gamma dapat menghambat pertumbuhan benih, sehingga membutuhkan waktu lebih lama untuk tumbuh dan menurunkan viabilitas benih. Secara morfologi, hal itu juga menurunkan tinggi tanaman, diameter batang, ukuran daun, dan jumlah daun. Secara anatomi, kepadatan stomata berkorelasi positif dengan tinggi tanaman dengan nilai korelasi adalah 90% dan 74%. Iradiasi sinar gamma dapat meningkatkan keragaman morfologi hingga 30%. Pemotongan benih setelah iradiasi dapat meningkatkan keragaman dan tingkat kelangsungan hidup manggis. Kata kunci: Garcinia mangostana, sinar gamma, keragaman genetik

Reformulating the Contract Formats of Islamic Financial Institutions in Indonesia Toward Maqâshid Al-Syarî'ah-Based Contracts

This research aims to reveal the legal facts regarding the substance of the contract clauses in Islamic financial institutions such as Islamic banking, shariah pawn-shop, and takâful (sharia insurance) which show the nuance of capitalistic con-tract clauses. Based on the purpose of this paper, the scope of this study is limited to the normative contracts in several Islamic financial institutions in order to ref-lect the purity of the sharia norms as well as to produce a format of sharia contract that puts forward maqâshid al-syarî'ah as the basic orientation. To sharpen the analysis framework, this study applies normative legal method with a con-ceptual approach. It is found that several contracts in Islamic financial insti-tutions use money as the object of the agreement (contract). Of course, if it goes uncontrolled, it could potentially trap other parties in the contracts into the prac-tice usury (ribâ). In conclusion, it is necessary to reformulate the contract format of the Islamic financial institutions in order to make it in line with the maqâshid al-syarî'ah so that it could benefit the costumers of the sharia economy.Copyright (c) 2016 by KARSA.
