Ruminant animals was a group of mammals that chew the cud or eat the food there was swallowed. In Sumbawa district, there was 10 ruminant livestock diseases that are often infected by anthrax, brucellosis, snoring or septichaemia epizootica (SE), mucus or bovine epheral fever (BEF), surra worm or thelazia, scabies and abdominal bloating. One of the obstacles in order to increase the productivity of livestock was the existence of various diseases there was any effect on the life of livestock. This system aimed to make it easier for farmers to obtained information about diseases in their animals System tested methods used to test this system was black box testing, system accuracy tested with expert, questionnaire and precision and recall accuracy tested, black box test results show all existing functions was running well. testing between the system with the expert obtained an accuracy of 93% ,. Testing questionnaire got result of conformity assessment system to user requirement or breeder with answer agreed equal to 62.68%. The testing of precision and recall obtained the result of precision testing of 95.5% and recall of 8.3%, So it can be concluded that this system was in accordance with the needs of users.

â€ Perkembangan teknologi informasi dan sistem informasi yang demikian pesat di era sekarang ini telah membuat hampir semua aspek kehidupan tidak dapat terhindar dari penggunaan perangkat komputer. Praktek Kerja Lapangan (PKL) merupakan salah satu mata kuliah yang wajib ditempuh oleh seluruh mahasiswa Program Studi Teknik Informatika (PSTI) Fakultas Teknik Universitas Mataram. Proses administrasi PKL pada PSTI secara manual, mulai dari proses pengajuan PKL, pengajuan dosen pembimbing sampai pendaftar seminar PKL. Untuk penulis memandang perlu adanya suatu sistem informasi Praktek Kerja Lapangan pada Program Studi Teknik Informatika Universitas Mataram dengan tujuan untuk memudahkan pelaksanaan PKL pada Program Studi Teknik Informatika. Metode yang digunakan dalam membangun sistem informasi ini adalah metode extreme programming di mana dalam metode ini menekankan pengembangan sistem dalam skala waktu yang singkat, produktivitas, fleksibilitas dan kerja sama tim. Pengembangan dengan extreme programming menggunakan model iterasi dalam proses pengerjaannya yang meliputi proses planning, design, coding dan testing. Dalam proses testing penulis menggunakan model User Acceptance Test yang merupakan suatu proses uji untuk memenuhi sistem yang dikembangkan dapat diterima oleh pengguna. Berdasarkan hasil uji yang dilakukan pada sistem informasi PKL yang dibuat dengan metode User Acceptance Test yang diujikan pada 5 (lima) responden yang terdiri dosen, ketua program studi, staf program studi, mahasiswa dan kepala lab dapat disimpulkan bahwa fitur-fitur pada sistem tersebut telah memenuhi kebutuhan sistem yang diusulkan.

Alphanumeric writing ability is the main provision for children to be able to understand the subjects given in school. One alternative to help increase children's interest and ability in learning to write Alphanumeric is to use learning media in the form of software. This study is to create an application that presents Alphanumeric writing learning that is intentionally packaged in the form of a game in order to increase the learning interest of pre-school age children. In this study used the method of recognition of character letters made by the player. In character recognition, the application will record the handwriting that the user has created on the board provided. The handwriting will then be used at the image processing stage that uses Tesseract as the recognition engine. And from the results of the trials, pre-school children easily manage it.

This entitled of research "Expert System Diagnosis Eye Diseases Using MethodCertainty Factor Based Android" is proposed due to the increased spread eye diseases thatis leads to blindness in Indonesia it is happened because of the limited facilities of eyehealth services in health centers and hospitals, as well as lack of eye doctor who canexamine the eye, making eye left untreated and can cause serious damage to the eye.Therefore, many people are already suffering from the early symptoms of blindnessletting untreated without properly treatment. The purpose of this study is to develop anexpert system that is capable of providing information about eye diseases along withsuggested solutions of the disease suffered by imitating the analysis of an eye doctor.The system is built using certainty factor method which is an algorithm that isimprove the uncertainty idea of an expert. This method is used to describe the level ofconfidence of experts on issues being addressed. This system is built by Ionic frameworkfor Android applications with PHP, HTML5 and AngularJS.The system is able to provide information about eye diseases through the processof diagnosis, that can be used for early treatment of eye diseases. The whole function ofthis expert system application already worked properly without any mistakes. Anddiagnostics accuracy rate of the system is 75% in the diagnosis process of 15 diseases and52 symptoms.

The most widely circulated standard WLAN network in the market today is IEEE 802.11n. To build a more practical WLAN network using UR and WDS techniques. This study aims to measure and analyze the effect of the number of clients and distance to the quality of WLAN networks using UR and WDS techniques with parameters of bandwidth, jitter, and packet loss. The results of data analysis are known that the more clients and the further distance the transmission can reduce the quality of UR and WDS networks. The best network quality is generated UR network at 7.5 m distance with bandwidth average of 11934.7035 Kbps, jitter average 2,3563135 ms, and packet loss average 1.90% compared to WDS network with average bandwidth 3846.9135 Kbps, average jitter 9.496095 ms, and packet loss average 5.23%. The worst quality network produced by WDS network at 30 m distance with bandwidth average of 898.32735 Kbps, jitter average of 37.32591 ms, and the average packet loss of 47.10% compared to UR network with an average bandwidth of 8859,797 Kbps, the average jitter 13.082195 ms, and the average packet loss of 19.24%. The overall result of the measurement is known that UR technique is superior to WDS in building a WLAN network.
