Analysis of the usage of the android-based scantling calculation application for wooden ship construction for survey activity based on BKI vol vii 2013 rules

Abstract

In survey activities at wooden shipyards, surveyors often find scantling calculations not comply with the regulations. Because the use of technology has not yet developed, based on traditional technology development so that the weakness occurs in the design and construction. The survey system for scantling calculation is yet manually, surveyors write actual results and carry documents in paper form which is less efficient. Designing media in the form of android application for calculating wooden ship scantling based on BKI Volume VII 2013 rules concerning ‘Rules for Small Vessel Up to 24 M’ is needed. The initial step of a design application is creating database structure that normalization BKI table become a system, then, making a mock up for display. After that, create functional as back end system that is processing database and front end that is screen display, and the last step is creating system for reporting result. This application accessed by input the actual data of wood type, mechanical properties and main dimension on each form, then the application will display the results of BKI calculations. The surveyor fills actual data of scantling in column and gives mark if the results comply and will gives a note if not complied then insert a photo to prove. The PELRA ship with length overall (LOA) of 17.65 meters used as the research object. The questionnaire is applied to know response of user about the application. The results, a total percentage is 75.6% to average total score is 37.8 which shows that the application very helpful to assist survey activities. The conclusion, the use of android application for scantling calculation of wooden ship construction is needed because more practical and can accessed anywhere compared to manual survey systems, more efficient in terms of time, and more safety for data storage of report.
