Abstract

The Fuzzy Logic concept was first introduced by Prof. Lotfi Zadeh from the University of California at Berkeley in 1965, and presented not as a control methodology, but as a way of processing data by allowing the use of partial set membership compared to the crisp set membership or non-membership. Along with the development of computer technology, the concept of fuzzy logic is increasingly needed by people, because this concept is able to provide information needed in the decision making process. This study aims to analyze and design intelligent systems to monitor the health development of inpatients. The method used is the Fuzzy Logic method. This method will predict the level (degree) of health of each patient based on the amount of drug use and the durationof diagnosis process. The tools used to analyze and design the system are Unified Modeling Language. The results of this research are monitoring the health development of patients using the Fuzzy Logic method.

Abstract

SMA Padamu Negeri Medan adalah sekolah yang memiliki dua jurusan yaitu IPA dan IPS. Proses pembelajaran masih bersifat konvensional, bahwa proses belajar mengajar antara siswa dengan guru hanya dilakukan dengan terjadinya pertemuan antara siswa dengan guru di dalam kelas. Jika guru yang bersangkutan tidak hadir dan waktu pembelajaran yang dibatasi pihak sekolah, maka secara otomatis proses pembelajaran pun akan terhambat. Berbagai konsep dan teknik baru dalam pengajaran telah banyak dikembangkan untuk menggantikan metode tradisional yang hanya mengandalkan pada metode pengajaran satu arah di kelas. Salah satu metode pengajaran yang sedang berkembang di masa sekarang adalah e-learning. E-learning dapat membantu parapengajar dalam mendistribusikan bahan ajar mereka tanpa harus berada di kelas dengan menggunakan internet, hal ini dapat memaksimalkan waktu pembelajaran di kelas yang terbatas. Pengembangan sistem informasi dalam pembuatan perangkat lunak menggunakan metode Waterfall dan dalam pembuatan perangkat lunak ini menggunakan PHP sebagai bahasa script yang digunakan untuk membuat halaman website dan MySQL sebagai database tempat penyimpanan data. Dengan adanya e-learning ini dapat membantu proses belajar mengajar agar lebih optimal. Memudahkan para guru untuk dapat mendistribusikan materi pelajaran untuk siswa/i di SMA Padamu Negeri Medan dan juga siswa/i dapat dengan mudah mendapat materi pelajaran. Website e-learning ini dapat dijadikan media diskusi tambahan untuk membahas materi pelajaran yang belum tuntas serta dapat mengerjakan soal-soal ujian berupa pilihan ganda dan mengumpulkan tugas-tugas yang di berikan oleh guru.

Abstract

Kebutuhan masyarakat secara umum akan sebuah hiburan saat ini sangatlah tinggi, salah satu media hiburan yang terpopuler ialah televisi. Namun televise konvensional sudah tidak lagi mampu mengimbangi tingkat mobilitas masyarakat yang semakin meningkat. Selain televisi, kebutuhan masyarakat akan penggunaan internet juga cukup tinggi. Memang sudah ada saluran televisi online yang disediakan tetapi permasalahan yang ditimbulkan ada pada kecepatan karena TV online diakses melalui web dan resource pada web. Terdapat juga iklan pada web, content web dan juga pengaruh jaringan serta web yang pada dasarnya tidak khusus untuk TV online, sehingga membuat TV online menjadi sangat lambat. Untuk mengatasi hal tersebut dirancang sebuah sistem yang bias menyediakan saluran TV online dengan menggunakan fasilitas internet tanpa perlu adanya banner ataupun konten lain seperti halnya pada website TV online. Siaran yang tergambar kemudian disiarkan ke jaringan lokal menggunakan aplikasi Visual Basic .NET 2010. Dengan adanya server televise streaming yang dapat diaplikasikan untuk broadcasting televise sendiri dalam suatu jaringan computer lokal, diharapkan mampu menjawab permasalahan yang dihadapi para pengguna khususnya dalam kemudahan menikmati siaran televisi

Abstract

Sundanese are tribes from West Java and Banten that use their own local language known as Sundanese. The large number of local residents who still use Sundanese in communicating daily is an obstacle in increasing tourist visits to the area. Then a translator is needed which can be used as a liaison between tourists and local residents so that there is no miscommunication between the two. But the increasing number of tourists, there is a lack of the number of translators needed, so it needs to be made a translator application by utilizing the development of computer technology. The application developed is an Indonesian-Sundanese to translate in the form of words using the IDA* algorithm. This algorithm is an A* algorithm whose depth is limited to each search iteration. Although the time complexity is higher than that of the A* algorithm, the IDA* algorithm does not require as much memory as needed by the A* algorithm. Then the IDA* algorithm is used in this study. The results of this study indicate that the IDA* algorithm can be implemented to convert translate words in Indonesian and Sundanese based on the estimation value of the smallest total cost of each word stored in the database, where the word that has the smallest total cost estimationcan be selected as a result of the translation.
