Determination of damage and losses after natural disasters is carried out to determine the type of damage and the amount of loss after natural disasters that must be borne by the government. In order for the type of damage and the magnitude of the loss after natural disasters according to the data in the field, a study is carried out that implements the Decision Support System (DSS) with the Weighted Product (WP) method. The results obtained are tests of pattern data which are calculated using Weighted Product (WP) compared to 3 different test data, namely using damage and loss data after the natural disaster in East Java in 2010, 2011. The results of the 3 test data used the first amount of 373 data, which produces precision 56.50%, recall 50.50%, accuracy 53.30%, and f-measure 39.10%. For the second data using the data 77, which produces precision 52.80%, recall 36.30%, accuracy 43.02%, and f-measure 36.30%. And for the third data using data from data 24, which produces 50% precision, 50% recall, 50% accuracy, and 50% f-measure. From the 3 types of test data used can be concluded that the Weighted Product (WP) method has a high level of precision, f-measure, recall, and accuracy if the amount of data used is increasing.

The boarding school information system is a system that provides information to support the operational, management, and decision making functions of an organization. Information sources within the information system that support day-to-day management operations such as transaction processing, status clarification, and so on. Boarding school information systems generally consist of a variety of systems, including welfare systems, management, premises, procedures and policies, and staffing. With a variety of systems in a boarding school information system, it is necessary to integrate between systems that aim to avoid data duplication in each system and increase system flexibility which can be achieved by utilizing web service technology. The purpose of this study is to design a web service on boarding school information systems that conform to 52 boarding school minimum standards set by the Welsh Assembly Government. The results of the development of an information system web service design is to map class diagrams that will be made on the web service design. AbstrakSistem informasi boarding school merupakan sistem yang menyediakan informasi untuk mendukung kegiatan operasional, manajemen, dan fungsi pengambilan keputusan dari suatu organisasi. Sumber informasi yang ada di dalam sistem informasi tersebut yang mendukung operasi manajemen sehari-hari seperti pengolahan transaksi, penjelasan status, dan lain sebagainya. Sistem informasi boarding school secara umum terdiri dari berbagai macam sistem, diantaranya seperti sistem kesejahteraan, manajemen, premis, prosedur dan kebijakan, serta staffing. Dengan adanya berbagai system dalam sebuah sistem informasi boarding school, maka perlu adanya integrasi antar sistem yang bertujuan untuk menghindari adanya duplikasi data di setiap sistem dan meningkatkan fleksibilitas sistem yang mana hal itu bisa dicapai dengan memanfaatkan teknologi web service. Tujuan penelitian ini adalah merancang web service pada sistem informasi boarding school yang sesuai dengan Standar 52 standar minimum boarding school yang telah ditetapkan Oleh Welsh Assembly Goverment. Hasil pengembangan rancangan web service sistem informasi yaitu dengan memetakan class diagram yang akan dibuat pada perancangan web service.
