Benefit–Cost Analysis of Maintenance Decision Support System

The procurement process became one of the important aspects for PT. PLN (Persero) to operate the company. One way to meet these needs is through the project tender. The tender process aims to get high-grade materials with the lowest prices that meet the criteria of efficiency PT. PLN (Persero). In order to simplify the bidding process required a decision support system. The method used in this system is Benefit Cost Ratio (BCR). Input in this application are the documents and the tender offer price from bidders with complete tender documents that have been validated by prospective bidders and then selected by the tender committee to make an assessment and validation winner. The output of this process is the winner of the tender project based on calculations Benefit Cost Ratio (BCR). Therefore, the method Benefit Cost Ratio (BCR) can be used as a decision support system to determine the winner of the project tender.

The implementation of decision support system will be applied to support the regional investment of West Sumatera by providing a feasibility study analysis; exclusively the aspects of economic and financial criteria. This research was carried out in West Sumatera Regional Investment Coordinating Board as the authorities of regional investment licensing and controlling. The first step in designing a decision support system is conducting Pre – Study. It consists of literature study and pre–design study related to field of study. Next step is using Unified Modeling Language (UML) method to provide, represent and visualize the system. The basic model of financial feasibility study is implemented by using the predetermined assumption as the scope of the best system performance. The system design which is implemented uses the Web and GIS concept. Otherwise, the expected result from the research is the application is able to calculate the basic data from financial feasibility aspect into needed information in order to analyze the feasibility of any investments. The result should be converted into Net Present Value, Benefit Cost Ratio, Internal Rate of Returns, and Payback Period value. The last step of the research is verification and validation in order to make sure the ability of application accommodating the pre -design system requirements. The result of verification and validation is able to accommodate the pre -designsystem requirements conclusively.Keywords: Feasibility, Financial, Investment, Decision Support System, GISAbstrakPerancangan Sistem Penujang Keputusan (SPK) ini dilakukan dalam upaya mendukung promosi investasi daerah dengan menyediakan sebuah aplikasi yang dapat membantu memberikan penilaian terhadap kelayakan sebuah investasi yang dilihat dari sisi ekonomi finansialnya. Penelitian ini di lakukan di BKPMP (Badan Kordinasi Penanaman Modal Provinsi Sumatera Barat) sebagai pihak berwenang dalam menentukan perizinan dan pengawasan investasi provinsi. Tahapan awal adalah dengan melakukan studi pendahuluan terhadap kajian bidang terkait. Tahap selanjutnya dengan menggunakan metode UML (Unified Modelling Language) yang memberikan gambaran visual dari sistem yang dirancang. Implementasi nyata dari sistem dengan menetapkan model dasar (modelbase) kelayakan finansial standar dengan beberapa asumsi sebagai ruang lingkup perancangan aplikasi. Perancangan aplikasi dilakukan dengan mengintegrasikan konsep Web dan GIS. Kemampuan aplikasi dalam menyediakan hasil pengolahan data-data dasar yang dibutuhkan pada sebuah kelayakan finansial dan mengkonversinya kedalam kriteria kelayakan investasi seperti Net Present Value, Benefit Cost Ratio, Internal Rate of Returns, dan Payback Period. Setelah dilakukan tahap perancangan aplikasi, maka dilakukan verifikasi dan validasi terhadap aplikasi yang dirancang. Hal ini ditujukan agar dapat dilihat apakah aplikasi telah mampu mengakomodasi setiap fungsi yang ada pada rancangan awal. Dari hasil verifikasi dan validasi telah dapat disimpulkan bahwa aplikasi ini dapat berjalan sesuai dengan harapan.Kata kunci: Kelayakan, Finansial, Investasi, Sistem Penunjang Keputusan, GIS
