Abstract

This research was development research that aimed to develop and produce a Statistics textbook model that supported with ICT and portfolio based assessment. This book was designed to improve students ability in communication and mathematical connections. There were three stages in this research i.e. define, design, and develop. The textbooks consisted of 10 chapters which each chapter contains introduction, core materials and include examples and exercises. The textbook developed phase begins with the early stages of designed the book (draft 1) which then validated by experts. Revision of draft 1 produced draft 2 which then limited test for readability test book. Furthermore, revision of draft 2 produced textbook draft 3 which simulated on a small sample to produced a valid model textbook. The data were analyzed with descriptive statistics. The analysis showed that the Statistics textbook model that supported with ICT and portfolio based assessment valid and fill up the criteria of practicality.

Abstract

Technological development is growing rapidly among with the increasing of human needs especially in mobile technology where the technology that often be used is android. The existence of this android facilitates the user in access of information. This android can be used for healthy needs, for example is detecting dental disease. One of the branches of computer science that can help society in detecting dental disease is expert system. In this research, making expert system to diagnosis dental disease by using certainty factor method. Dental disease diagnosis application can diagnose the patient based on griping of the patient about dental disease so it can be obtained diseases possibility of the patient itself. This application is an expert system application that operates on android platform. Furthermore, in the measurement accuracy of the system test performed by 20 patients, there were 19 cases of corresponding and 1 cases that do not fit. So, from system testing performed by 20 patients resulted in a 95% accuracy rate.

Abstract

Saat ini, pengembangan e-learning berbasis web menjadi tren dalam dunia pendidikan. Oleh karena itu, dalam penelitian ini penulis mengembangkan E-Stats berbasis web bidang ilmu statistik yang secara khusus dikembangkan di Universitas Negeri Semarang (UNNES). E-Stats menyediakan layanan akses artikel, jurnal dan materi tentang statistik. Artikel dan abstrak jurnal statistik dapat diakses oleh umum. Sedangkan jika menjadi member memiliki prevelege untuk mendownload jurnal dan materi yang sudah di-upload. Bagi member dapat mendaftar melalui form registrasi yang disediakan di halaman registrasi web. Desain E-Stats melalui tahap prototype (analisis, perancangan, desain sistem, ERD dan desain skema database), pemrograman, pengujian dan pemeliharaan. Melalui E-Stats, pembelajaran statistika dapat diakses online tanpa batas ruang dan waktu.

Abstract

Issue handling of inadvertence situations in the decision-making process of recruiting new employees at PT. Warta Media Nusantara that use criteria value of interviews, field test, a psychological test and medical check-up requires Multi Attribute Decision Making (MADM) as an auxiliary method of decision-making on the prospective eligible employee to be accepted in the company. There are various MADM methods, such as Simple Additive Weighting (SAW) method and Weighted Product (WP) method. Both of these methods are known as the most common method used in handling MADM issues, so in this study both methods are applied to the DSS and analyzed the differences in terms of obtained results and the execution time required for each method. The results of the study of the application of SAW and WP methods in the recruitment of new employees DSS there are some differences in the results of the candidates rank order and the differences in execution time of each method. The differences in rank order of these methods are due to the effects of alternative values, weighting criteria, and the calculation method. WP method is able to provide more rigorous result than SAW method, while the difference in execution time of SAW and WP methods explains that the execution time of SAW method relatively quick because SAW calculation method has a simpler process than the process of WP calculation methods
