In 2010, 51% of 39 million blindness are caused by cataract. In 2013, there are 1.8% of 1.027.763 Indonesian people who suffered from cataract. Half of them are not treated yet due to their ignorance on the cataract disease. Therefore, in this research, we tried to build a system that can detect early cataract disease as the ophthalmologist would do. The system will use C4.5 algorithm that receives 150 training data set as an input, resulting in a set of rules which can be used as decision factors. To test the system, k-fold cross validation technique is been used with k equals to 10. From the analysis result, the accuracy of the system is 93.2% to detect cataract disease and 80.5% to detect the type of cataract disease one might suffered. Index terms-C4.5 algorithm, cataract, k-fold cross validation, machine learning

Penerapan Metode Certainty Factor dalam Sistem Pakar Pendeteksi Resiko Osteoporosis dan Osteoarthritis Stephanie Halim; Seng Hansun

Osteoporosis is commonly referred to “thinning” and osteoarthritis referred to “calcification”, but people giving wrong action treatment of these two diseases. Therefore, the aim of this study is to develop an android-based application to identify the risk of osteoporosis and osteoarthritis. To identify that risk was processed using certainty factor method. Certainty factor method related about event based on facts, which the source of those facts are from expert and assumed with a value, called certainty factor. From the testing result, the accuracy of this expert system is about 80%. Index Terms - Certainty factor, disease diagnose, expert system, osteoarthritis, osteoporosis

Food is something that can not be separated from the life of every human being. Its variation makes a lot of people interested in tasting many types of food, even they have not known yet. The detail information of restaurants, especially their location could be a problem. So, the restaurants recommendation website is made to help them. The recommendations are given by the Squeezer algorithm using the user’s input as references. The accuracy of the given recommendations are determined from the amount and consistency of the user at the time of selecting the item. The Term Frequency Ranking is used as a searching feature to display the search results in ordered manner by their relevancy rank. Experiment result shows that the Term Frequency Ranking gives high value of Recall, 1, and 0.46 for the Precision value. Index Terms—Recommended System, Squeezer, Term Frequency Ranking, Website.

Implementasi Audio Steganografi menggunakan 4th LSB dan Advanced Encryption Standard pada Windows Phone M. Chaeril Maricar; Seng Hansun

Securing data during transmission become one of the problem in technology, those data can be intercepted and read by others. One preventive action to overcome this is by using steganography. This thesis implements an audio steganography using Windows Phone. Combination of Advanced Encryption Standard to secure data and Audio Wave Steganography which embedded data inside 4th LSB layer, resulting in increased safety and robustness against noise addition compared to 1st LSB. Index Terms—Advanced Encryption Standard, Audio Steganography, Audio Wave Steganography, Least Significant Bit, Windows Phone.

Pengembangan Aplikasi Pendukung Keputusan Pemilihan Program Studi dengan Metode Fuzzy Logic (Studi Kasus: Universitas Multimedia Nusantara) Joko Haryanto; Seng Hansun
Ultima Computing : Jurnal Sistem Komputer Vol 7 No 1 (2015): Ultima Computing : Jurnal Sistem Komputer
Publisher : Faculty of Engineering and Informatics, Universitas Multimedia Nusantara

This paper describes the development of decision support system application to assist students who want to enter college so that no one choose the majors incorrectly. This application uses fuzzy logic method because fuzzy logic is very flexible in data which are vague and can be represented as a linguistic variable. The purpose of this application is to assist students to choose available majors at University Multimedia Nusantara which are appropriate with his/her capabilities. This application accepts five kinds of input values i.e. Mathematics, Indonesian, English, Physics, and TIK. Received input will be processed by the calculation of the system for decision-making and the application will generate output that shows how great a match for each majors. With this application, prospective students can find out where the majors that match his/her capabilities. This application has ninety nine percentage of match result accuracy. Index Terms—fuzzy logic, decision support system, UMN, selection of major

Optimasi Pencarian Kata pada Aplikasi Penerjemah Bahasa Mandarin – Indonesia Berbasis Android dengan Algoritma Levenshtein Distance Peggy Peggy; Seng Hansun

In the Chinese-Indonesian language translator application on electronic device, such as Android, input is all about pinyin. Sometimes, some errors could occured. User can not find the word which he is searching for. These errors can increase the number of processing time. A solution to solve these errors is performing optimization on the application, i.e. by providing some alternative approaches word which typed by user. Application will sort alternative words according to the smallest distance to the largest distance. Then, application will display alternative words order from top priority which has the smallest distance, to low priority which has the largest distance. In brief, translator application with optimization is useful to shorten processing time of translating from Chinese to Indonesian by providing alternative words. Optimization is done with Levenshtein Distance algorithm. Levenshtein Distance algorithm will calculate the difference between the distance of the word user typed among alternative words. Index Terms─Android, Chinese, Indonesian, Levenshtein Distance, optimization, translator application

A Data mining is the activity that includes the collection, the use of historical data to discover regularity, patterns and relationship in a large data set. The usefulness of data mining is to specify a pattern to be found in the data mining task. The presences of data mining is motivated by the problem of data explosion which had been experienced lately these day where many organization or company collect so many years of data (purchasing data, sales data, damage data item, transaction data, and so on). In this paper data mining methods been used to analyze the damage data of finished products, with the goal of producing a pattern of the damage product. Based on the pattern from product’s damage, can be see and the aspects that affect to the damaged product. The purpose of this study is to show information about the relationship of damage data of finished goods using C4.5 algorithms in PT. Kayu Lapis Asli Murni, and display results in the form of a decision tree mining. Index Terms—data mining, C4.5 algorithms, decision tree, damage data of finished products, PT. Kayu Lapis Asli Murni
