120 IPTEK, The Journal for Technology and Science, Vol. 23, Number 3, August 2012 Modelling Ports Investment and Island Economic Growth Marcus Tukan 1 , Tri Achmadi 2 , Sjarief Wijaja 2 , and Udisubakti Ciptomulyono 3 AbstractThe port is a gateway region's economy. Investment performance is important that an effective and efficient port to ensure smooth supply chain needs of the region and promote economic growth. This study aims to model the port investment relationship with economic growth. Quantitative analysis and econometric modeling is used in statistical testing, studies typically classified in two areas, namely: the north and south islands of Maluku. The northern and southern regions and the increase in the loading dock term investment to drive economic growth, but the number of visits relation ship with economic growth negative influence. Keywordsharbor, investment, growth, econometric Abstrak—Pelabuhan merupakan gerbang perekonomian wilayah. Investasi menjadi penting kinerja pelabuhan yang efektif dan efisien dapat menjamin kelancaran rantai pasok kebutuhan wilayah dan mendorong pertumbuhan ekonomi. Kajian ini bertujuan memodelkan hubungan investasi pelabuhan dengan pertumbuhan ekonomi. Analisis kuantitatif dan pemodelan ekonometrika digunakan dalam pengujian statistik, kajian diklasifikasikan pada dua tipikal wilayah, yaitu: Utara dan Selatan kepulauan Maluku. Wilayah Utara dan wilayah Selatan peningkatan bongkar-muat dan investasi panjang dermaga dapat mendorong pertumbuhan ekonomi, tetapi hubungan jumlah kunjungan kapal dengan pertumbuhan ekonomi memberikan pengaruh yang negatif Kata kunci—pelabuhan, investasi, pertumbuhan, ekonometrika I. INTRODUCTION 7 aluku Islands as a province of the study is important and is intended to model the relationship between investment in the port with a typical island growth, needs to get massive length of the berth, and the growth of loading and unloading ships in an effort to boost economic growth to be achieved at a certain level. Diversity and difference in potential resources and the availability of infrastructure owned by their respective island territories, creating a link between the islands of the other islands in the region itself as well as regional and international [1], these interactions have an impact on economic growth in the region diseputarnya, and will provide an overview of different approaches to the development of each region and can be classified based on the economic hierarchy. The amount invested in the sector if the harbor is an important variable in terms of the parameters of the underlying infrastructure, among others: the size of the port [quay length (L), the width of the pier (B), the depth of the pool, and supporting facilities], optimal ship size [deadweight (DWT / GT), vessel length (LOA)], as well as ship traffic (call) in an effort to increase the role of optimizing the performance of the port to support the economic activity of the islands. Port infrastructure investment is believed to encourage the economic growth of a region. Infrastructure and Long Run Economic Growth concluded that the positive effects of investment in transport and communication to economic growth [2].

Indonesia. across sectors such that the infrastructure must be having a real effect on the performance of the transport network and changes in economic behavior [3]. Measuring the impact of infrastructure investment on the development of a State, [4], as well as the achievement of certain economic level is believed to promote the development of the transport system more effective and efficient [5]. The process of implementation of sustainable development policies and infrastructure development is one important dimension in strategic planning will ensure the development of the region and the socio- economic development of a country, [6]. The infrastructure of the port area where the focus of the supply chain is to find the most effective and efficient in implementing value-added, in order to obtain a solution the complex issues related to consumer demand, [7]. Use of Transport Modes relationship with Sectoral Economic Growth in East Java, which uses observational methods restropektif with cross- sectional times series, correlation analysis, index and index LQ Wilkirson found a strong relationship between transport and economic growth, [8]. In the islands for every increase of loading / unloading goods by 1%, ceteris paribus, to encourage the economic growth of 0413%, which is generally the Maluku region is dominated by the charge and the length of the loading dock at 1% can affect growth economics at 0.0150% [9]. Picture of the port as a gateway to the region's economy has become the slogan of many scientific discussions and written prologue scientific, as described in the theory Button explained that transportation has a positive impact on development and economic growth, and vice versa increased production of goods and services can be attributed directly to the improvement of transport [10]. Concepts that bridge the global prospective to calculate the effect of transportation investment on both the micro and macro level, where the economic model was M
