Supplier selection is multicriteria problem, since for selecting the supplier who will become partner, decision maker must consider many criteria to measure supplier performance. One of the models that is used to measure supplier performance is Supplier Performance Rating used in Kingston-Warren Corporation. The key aspects related to that model are Quality, Cost and Delivery. One of tools that used by decision maker to select supplier is making a computer system that can interact with decision maker. The system is called Decision Support System (DSS) for supplier selection. The process of supplier selection uses Analytical Hierarchy Process (AHP) model. AHP model conduct supplier selection by making paired matrix comparison from defined criterion. Result of AHP model calculation is in the form of priority value, so that the highest priority value produced by the model is used by decision maker to choose the best candidate supplier.

Short Message Service (SMS) still has security problems with attempts to steal messages, intercept messages, hijack messages by parties who are not responsible for obtaining information. Cryptography is the science of maintaining the confidentiality of information from aspects that can threaten information security with certain mathematical algorithms and techniques. The Luc algorithm is a public key cryptographic algorithm that was developed using the lucas function. This study aims to implement the Luc algorithm on an Android-based SMS security application in the National Narcotics Agency of Central Sulawesi Province to maintain privacy in communication between the sender and recipient of the message. This application was created using an Android studio developer with the Java programming language. Based on the results of the first test for a sample of plain messages in the word KOTA PALU that uses public key 13 produces the message cipher P=Se!CQa. The second test result for the message sample on the word KOTA PALU that uses public key 29 generates the AD*`_$(NQ cipher message

ABSTRAKPenyakit lambung merupakan penyakit yang tidak bisa dianggap remeh, karena jika dibiarkan terus menerus dapat mengakibatkan penyakit yang lain muncul dan bisa juga menyebabkan kematian jika tidak segera ditangani. Penyakit lambung dapat disebabkan oleh pola makan yang tidak sesuai, beban pikiran dan juga infeksi yang disebabkan oleh bakteri. Dengan adanya permasalahan tersebut maka penelitian ini hanya dapat memberikan diagnosis penyakit lambung yaitu Gastritis, Dispepsia, dan Gerd. Gejala yang diberikan ke dalam sistem berdasarkan gejala dari dokter umum.Penelitian ini bertujuan untuk membuat sistem pakar diagnosa penyakit lambung menggunakan metode Case Based Reasoning (CBR), dimana dapat membantu para penderita lambung dalam mendiagnosa penyakit yang menyerang lambung, dengan menggunakan metode Case Based Reasoning (CBR). CBR dikembangkan dari sistem pembelajaran berbasis kesamaan (similarity) dan dengan perhitungan Certainty Factor.Berdasarkan pengujian dan analisis sistem pakar diagnosa penyakit lambung menggunakan metode Case Based Reasoning (CBR) berbasis Web, mampu mendiagnosis 3 penyakit lambung (Gastritis, Dispepsia, dan GERD) dengan perhitungan nilai kepastian menggunakan metode certainty factor dan perhitungan kemiripan dengan metode Case Based Reasoning (CBR).

Penelitian ini bertujuan untuk membangun sebuah sistem yang dapat memberikan informasi lokasi ATM di Kota Palu, dan sekaligus memberikan petunjuk jalur terpendek dengan menggunakan algoritma Ant Colony Optimization (ACO) system (ACS), yang merupakan variasi algoritma Ant Colony Optimization (ACO), dalam mencari makanan setiap setiap semut akan berusaha mencari jalur terpendek dari sarang ke tempat makanan. Kemudian semut tersebut akan meninggalkan pheromone di jalur yang dilaluinya .Pada proses awal algoritma ini adalah menginisialisasi penggunaan parameter yang tepat sesuai kasus yang akan diselesaikan .Pada proses ini semut akan memilihmelakukan eksploitasi atau eksplorasi rute yang akan di kunjungi. Eksploitasi berarti semut hanya akan mengunjungi ruas-ruas simpul yang memiliki pheromone yang tinggi dengan bobot jarak yang kecil sedangkan eksporasi berarti semut bias saja mengunjungi ruas ruas simpul yang memiliki pheromone yang rendah dengan bobot jarak besar. Proses perhitungan ACO di implementasikan ke dalam sistem yangtelah di buat menggunakan aplikasi Android studio versi 3.3 dengan memanfaatkan prosedur algoritma ACO, penelitian ini menggunakan data sebanyak 60 lokasi ATM dikota Palu

The problem of determining distribution routes can be categorized as Traveling Salesman Problem (TSP). TSP is a search for a sequence of locations where a salesman travels from the initial location to a list of locations which must be passed. Each location can only be visited once and ends at the initial location of departure. This study aims to resolve the problem of determining the distribution route for mineral water products at PT. Anugerah Wina Sentosa by implementing the Ant Colony System (ACS) algorithm to conduct route searches. The ACS algorithm is an algorithm adopted from the behavior of ants to determine the shortest route from the nest to the food source. Based on the research, the results of the ACS algorithm show that the greater the case to be resolved will affect the system execution time but still can produce the best distance route. The success of this algorithm is influenced by the determination of the value of the ACS parameter, namely Î², qo, q, Î±, ð™, the number of ants and the number of ant cycles determined by analyzing the TSP case to be resolved.
