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

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

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

Abstract

E-learning merupakan suatu jenis media untuk melakukan proses belajar mengajar secara mandiri yang memungkinkan tersampaikan bahan ajar ke mahasiswa melalui media jaringan komputer atau internet. E-learning semakin banyak digunakan oleh lembaga pendidikan karena mempermudah para pengguna untuk dapat mengakses dimanapun dan kapanpun tanpa adanya pembatasan ruang dan waktu sehingga mahasiswa dapat dengan leluasa memperoleh materi-materi kuliah yang ditempuh. Tetapi  untuk  e-learning yang  berbasis  web  ini dirasa  masih  banyak  yang  kekurangan  sehingga  dirasa  sangat  sulit digunakan atau tidak menarik penggunanya dan tidak dipakai secara efektif dan efisien sebagaimana mestinya. Hal ini dikarenakan usability pada web tidak diperhatikan sehingga hubungan interaksi antara manusia yang merupakan salah satu faktor penting dalam sebuah sistem terabaikan. Usabilitas terdiri dari learnability (mudah dipelajari), efficiency (efisien), memorability (kemudahan dalam mengingat), errors (pencegahan kesalahan), dan satisfaction (kepuasan pengguna). Penelitian ini bertujuan untuk mengukur seberapa tinggi tingkat usabilitas yang telah ada pada sistem dan bagaimana respon pengguna terhadap web e-learning tersebut. Hasil penelitian adalah tingkat usability dari website e-learning sehingga dapat mengetahui kriteria apa saja yang belum diperbaiki sebagai dasar pengembangan user interface dari e-learning tersebut.

Abstract

This research develops a decision support system for the selection of outstanding students by combining AHP and TOPSIS methods. AHP method was used because it could be implemented to this data and do the priority ranking process for each criterion based on pairwise comparison matrix. The TOPSIS method was used because the concept of the chosen alternative does not only have the shortest distance from the positive ideal solution, but also has the longest distance from the negative ideal solution. The purpose of this study was finding out the workings of the TOPSIS method and the AHP-TOPSIS combination method, as well as to find out the comparison of the best methods between TOPSIS and the combination method of AHP-TOPSIS in the selection of outstanding students. The concept of TOPSIS is simple and easy to understand and has the ability to measure decision alternatives while AHP is not chosen because the AHP method is widely used in the case of criteria weighting and priority determination of each criterion. However, if the two methods were combined the results will be better because in AHP there is an eigenvector concept which is used to do the priority ranking process for each criterion based on pairwise comparison matrix, then the results of the weighting criteria are processed by the TOPSIS method for ranking process. The application of the TOPSIS method on the selection of outstanding students can be analyzed with the results of the presentation using Hamming Distance incompatibility is 93%. Meanwhile, the application of the AHP-TOPSIS combination method gets the presentation results using Hamming Distance incompatibility is 91%. Based on these results in this study it can be concluded that the AHP-TOPSIS combination method is better than the TOPSIS method.
