Abstract

Disease THT (Telinga, Hidung dan Tenggorokan) is a public health problem, because it often occurs without knowing the season. This disease can affect various ages. This expert system development process is done using backward chaining inference engine where the search process starts from the facts to further toward a conclusion. In addition serves to lighten the work of doctors, expert systems developed will also be very beneficial to the general public in accessing information about THT diseases such as diagnosis and therapy. With this application will help users and THT physicians in performingservice and access to information related to the diagnosis of THT diseases

Abstract

The expert system is an artificial intelligence, expert systems is a program to store and process knowledge for a particular area, that's why they were able to answer questions and solve problems, according to the consensus of the experts. Backward Chainning models in reverse of the hypothesis, a potential or conclusion which must be proved by the facts that support the hypothesis.Backward Chainning also well described in the form of reasoning began with the goal to the subgoal reach the goal of understanding means fulfilling subgoal. Decision tree is the result of a tracking process that can be used to explain the answer to the question of questions. Chainning Backward algorithm uses primary data structure in the formation of the decision tree. In the knowledge base necessary rules which will be stored in the database. For the rules on the formation of the expert system can be made based on the facts mentioned above. To rule pin test rules that generate multimeter to measure the use of transistors is right and wrong. Read the scale rule is a rule of the final results of the test transistors are good, leaking or broken so it can not be used anymore

Abstract

A quiz application that has element of Mobile Learning (M-Learning) in the Smartphone can certainly provide an attractive entertainment to the users, and can provide instructional media to add knowledge. Quiz is a form of game or mind in which the players (as individuals or in teams) attempt toanswer questions correctly to achieve the goal in learning. In this application, the users will be asked some questions about general knowledge, so the users are forced to think in answering the questions.The method used in the design of this application is the Linear Congruential Generator (LCG) method and the String Matching (SM) method, in which the LCG method functions to randomize question on the application, while the SM method functions to match the selected answer "true and false".

Abstract

Knowledge of skin disease in cattle in the community in an effort to identify early disease to make their own decisions is still low. Dependence on knowledge Veterinarian for detecting cow skin disease remains a top priority, especially for cattle farmers in Rokan Hulu in an effort to determine a skin disease that threatens their cow. So the cost to society is quite expensive and also seen from time highly inefficient. Therefore, the use of media consulting expert system-based computer that uses factsand reasoning techniques in solving the problems of the dairy farmers in Rokan Hulu can be solved by the method of Forward Chaining. Application Expert System produces output in the form of an application program or tool that can be used to diagnose the possibility of skin disease in cattle based on symptoms entered by the user and the application is using a technique or method trace forward (forward chaining) to make sense of cow skin diseases. Testing of the system shows that the system isable to perform diagnostics cow skin diseases based on symptoms suffered. This application was built using Microsoft programming language Visual Basic 6.0 and its data processing applications with Microsoft Access 2003

Abstract

Nomor Unik Pendidik dan Tenaga Kependidikan (NUPTK) merupakan data penting bagi Departemen Pendidikan Nasional. NUPTK terdiri dari 16 angka yang bersifat tetap karena NUPTK yang dimiliki seorang Pendidik dan Tenaga Kependidikan (PTK) tidak akan berubah meskipun yang bersangkutan telah berpindah tempat mengajar atau terjadi perubahan data periwayatan. Pada program sertifikasi, PTK diwajibkan mengumpulkan data diri berupa Nomor Identitas (ID), kepemilikan NUPTK, tingkat pendidikan, usia, masa kerja, golongan guru dan jenissertifikasi. Dari data-data ini, akan ditentukan seseorang lulus atau tidak dalam sertifikasi guru.Dalam menentukan kelulusan, dibuatlah suatu syarat-syarat tertentu yang menjadi acuan penilaian. Tetapi diperlukan suatu syarat yang menjadi prioritas utama penetapan kelulusan sertifikasi guru. Algoritma C4.5 adalah merupakan salah satu algoritma dalam teknik klasifikasidata yang menghasilkan satu pohon keputusan. Dari pohon keputusan yang dihasilkan maka akan terdapat beberapa rule atau pengetahuan untuk suatu kasus. Teknik klasifikasi yang akan digunakan adalah Decision tree, yaitu algoritma C4.5. Dengan implementasi Algoritma C4.5dapat membantu pihak pengambil keputusan/kebijakan dalam menentukan calon sertifikasi guru layak atau dipertimbangkan untuk mengikuti Pendidikan Profesi Guru Dalam Jabatan (PPGJ).

Abstract

Weighted Product merupakan salah satu metode yang digunakan dalam menyelesaikan masalah FADM (Fuzzy Multi Atribute Decision Making). Weighted Product memerlukan proses normalisasi karena mengalikan hasil penilaian setiap attribute, hasil perkalian belum bermakna jikabelum dibandingkan dengan nilai standar. Bobot untuk attribute berfungsi sebagai pangkat positif dalam proses perkalian, sementara bobot biaya berfungsi sebagai pangkat negatif. Tahapan yang dilakukan dalam proses Metode Weighted product adalah dengan cara menggunakan perkalian untuk setiap rating kecocokan kriteria dan memangkatkan rating setiap kriteria dengan bobot kriteria yang bersangkutan. Metode ini digunakan untuk mencari alternatif terbaik dari sekian alternatif yang adadengan bobot yang terbaik. Dari penyelesaian tesis ini penulis melakukan penelitian dengan cara bagaimana menyeleksi calon nasabah dalam pemberian kredit modal usaha pada Bank Danamon Simpan Pinjam Ujung sesuai kriteria yang telah ditetapkan.

Abstract

PT. POI merupakan salah satu produsen obat besar di Indonesia. Walaupun perusahaan besar, namun sistem informasi penggajian karyawan masih dilakukan dengan cara manual, pemasukan data dilakukan satu persatu dari lembaran-lembaran kertas. Demikian pula penghitungan atau kalkulasi bulanan, terutama penghitungan pesangon karyawan yang keluar dan penghitungan hutang progressive karyawan masih dilakukan dengan cara menggunakan kalkulator. Sehingga dalam penghitungan dengan jumlah yang besar akan berdampak pada ketidakakuratan data dan tidak efisiensinya waktu karyawan serta pemborosan pengeluaran perusahaan. Agar semua masalah diatas dapat terpecahkan maka diperlukan sistem informasi penggajian yang baik, agar informasi yang dihasilkan akan akurat, tepat dan cepat diperlukannya penggunaan jaringan yang ada untuk mengirimkan file dari bagian lain kedalam bagian penggajian. Dengan penggunaan jaringan pada proses penghitungan pada bagian penggajian, maka jaringan yang ada pada perusahaan dapat lebih dioptimalkan penggunaannya.
