Abstract

West Java is one of the areas in Indonesia with high rainfall. One of the causes of frequent flooding in the DKI Jakarta area is due to receiving water from the West Java area. The method used in this study is the Association Rule using the Apriori algorithm and FP-Growth. Association rule is a rule in data mining in determining all association rules that meet the minimum support (minsup) and minimum confidence (minconf) requirements in a dataset. In this study, the minimum support used is 5 and the minimum confidence is 0.9. The purpose of this study was to obtain a pattern of rainfall intensity that often occurs every month in the measurement station areas. The measurement stations in the West Java region are the Citeko Meteorological Station, the Penggung Meteorological Post, the Kertajati Meteorological Station, the Bogor Climatology Station, and the Bandung Geophysics Station. The results of this study indicate that in April, May, June, October, and November there is no pattern of rain intensity that occurs between the measurement station areas. Heavy, very heavy, and extreme rains are very rare. In July, August, and September, most areas do not experience rain.

Abstract

The agricultural census dissemination website is one of the media created by BPS to publish the results of agricultural censuses in Indonesia. The last update of the agricultural census dissemination website was carried out in 2013 so that an update was needed related to the usefulness of the system and other features that were considered less relevant to the times. The website redesign process uses a user-centered design (UCD) approach with evaluation using a system usability scale (SUS) questionnaire. The initial evaluation questionnaire was distributed to 50 respondents consisting of various user groups, namely the ST secretariat, BPS employees, lecturers, students, and the general public. The purpose of this study is to determine the redesign and evaluation of the website interface for the dissemination of the agricultural census. Based on the initial evaluation, the SUS score obtained was 60.05 points. After the redesign, the final results of the evaluation obtained showed that the design of the solution resulting from the redesign of the system using the UCD approach was better than the initial design of the system.
