As an archipelagic country, Indonesia has stated that oceans are considered as connector, not as separator. Using that  concept,development of coastal and oceanic zone in Indonesia should involve interisland infrastructure development; it includes bridges, underwater canals, harbors as well as submarine cable and pipeline. Installation of submarine cable and pipeline is a high risk and high cost job that requires high accuracy and precise calculation. Therefore, it is necessary to have a good planning through optimization of submarine cable and pipeline route design. The optimal design of submarine cable and pipeline can be achieved by involving physical, environmental, socio-economical, laws and political factors in the analysis. Submarine cable network is needed for the distribution of electricity, telephone and internet between islands.

As the demand of information technology rise,as well as the growth of electricity needs,even for small islands though,the submarine cable installation work is growing intensively. Similarly, the underwater pipelines that are usually associated with the distribution of oil and gas, to distribute either some direct exploration results (e.g. crude oil) or some processing results. As an archipelagic country, Indonesia has a huge number of natural resources including oil and gas. It has numerous locations of petroleum exploitation which lies offshore, such as in the Makassar Strait, Strait of Karimata,South China Sea, Java Sea,Timor Sea and the Strait of Malacca.With such of facts,development of submarine pipelines to distribute the results of exploration and processing of oil and gas is absolutely necessary. One of standard for location criteria which can be traversed by paths or routes of submarine cable or pipeline is the American standard (ANSI) in its implementation. However, in determining the new location criteria are variables that must be taken into account without revealing the best value quantitively as the location of cable lines or underwater pipelines. The research is aimed to develop an optimization model for planning and design of submarine cable and pipeline. It was started with literature study related to considered factors in the route planning, identify and analyze some impacts to environmental and socio-economical factors due to installation of cable and pipeline.

IEEE Standard Nr.1120-2004 is used as a main documents for route planning.Field observations and measurements, interviews with some experts, collaboration with industrial stakeholders,development of numerical models, as well as spatial analysis using Geographic Information System (GIS) were carried out in this research.Twenty one variables (incl.physical and socio-economical variables) were identified for cable and pipeline design. Qualitative and quantitative analysis were carried out on the physical and the non-physical variables to have an optimum design of submarine cables and pipelines. To understand the characteristics of tidal currents and ocean in the study area and to determine the value of the maximum current in the planned route,numerical model approach was performed. Determination of the location and design of the submarine cables and pipelines was made with the classification of influencing variables, continued by weighting using Analytical Hierarchy Process (AHP) and at last the spatial analysis using the Simple Additive Weighting (SAW) in a GIS software. Table of list of variables,map of cable and pipeline design in Jakarta Bay and Cirebon Bay,as well as map of pre-lay survey result for actual submarine pipeline lying in Madura Strait were produced in this research. All of these effort were conducted in order not only to have a safe and lowest risk and cost in cable and pipeline lying,but also reducing negative impact of the installation.
