Ship waiting time is one issue that is always getting serious attention in every country. Marine transportation became the main made of transportation in trade. Nearly 90% of foreign trade is done by sea. Freight carried by sea to be very efficient due to large carring capacity and this the role of the port as a place where ships can carry out loading and unloading of goods becomes an important means of supporting adequate facilities and infrastructure. If the performance of the port is not optimal, it will have a direct impact on the service so that it will cause new problems, namely the ship’s waiting time gets higher, so that it  willlead to high costs, which have a direct impact on the price of goods on the market. This research has objective to know analysis the influence of factor ship scheduling, pilotage, and loading and unloading productivity to the waiting time. This research was conducted at the Port of Sei Kolak Kijang as a sample. The data collection done was through a method of observation, the literature study, interview, documentatuion and the questionnaires. Techique the analysis used is linear regression multiple with program assitance SPSS V.20. Based on the results of research and analysis produced equation: Y = 15.326 - 0,220 X1 - 0,178 X2 – 0,308 X3 + µ. Where the decision variable of waiting time (Y), ship scheduling (X1), pilotage (X2), loading and unloading productivity (X3) tested using t test show that the three independent variables significantly influence passenger decision as dependent variable.

Traditional wooden motorboats are ships that are built traditionally based on the experience of the builder without a basic design process like modern ships. The sizes of traditional wooden ships are usually small and are mostly used as fishing vessels, passenger ships and inter-island cargo ships, especially in eastern Indonesia. Traditional wooden motor boats have become a means of local transportation to serve shipping needs in the regions and as a means of local transportation. Sailing certainly has various problems which can be caused by weather factors, the condition of shipping lanes, other ships, and things beyond human capabilities, which can cause shipping disruptions and even cause emergencies. Emergency means a situation outside normal conditions that occurs on board a ship which has a tendency to endanger human life, property, objects and the environment where the ship is located. One way to anticipate emergency events is to provide safety equipment. IMO (International Marine Organization) as a maritime world organization issued SOLAS (Safety of Life at Sea) which contains provisions regarding what safety equipment is on board ships such as Life Jackets, Ring Buoys and Fire Extinguisher. However, in fact, fulfilling the safety equipment requires independent costs from traditional motorboat owners so there is a priority in fulfilling the safety equipment. Based on the results of the Analytical Hierarchy Process calculations in priority fulfillment of safety equipment with the final result of 36.6% Life Jacket, 30.8% Ring Buoy and 33.6% Fire Extinguisher. With these results, ship owners can determine their priorities in anticipating future emergencies
