Decision support systems are intended to be a tool for decision makers to expand their capabilities, but not to replace their judgment. This RTLH (Unfit for Living House) assistance must be right on target for poor people who meet the criteria as requirements for receiving RTLH assistance, so that residents who are unable to receive RTLH assistance can receive the assistance. In its implementation, the underprivileged population who is entitled to receive assistance unfit for habitation is determined by the Social Service (Dinsos). One of the methods in decision support is the Simple Multi Attribute Rating Technique (SMART) method or commonly abbreviated as the SMART method. The SMART method is a method that has minimum calculations and is very simple, but objective on the results of decision support. From research conducted using the SMART method, it was found that R9 with a final optimization value of 0.725 became the recipient of uninhabitable housing assistance from 10 alternative data on uninhabitable houses analyzed.</em></p> 2021-05-29T00:00:00+07:00 Copyright (c) 2021 JUKI : Jurnal Komputer dan Informatika https://ioinformatic.org/index.php/JUKI/article/view/40 Memprediksi Jumlah Siswa Baru Menggunakan Metode Backpropagation (STUDI KASUS: SMK HARAPAN BANGSA KUALA) 2021-06-03T18:08:37+07:00 Kris Jayanti krisj8106@gmail.com Katen Lumbanbatu katenlumbanbatu@gmail.com Suci Ramadani suciramadani@gmail.com <p><em>Artificial Neural Network (ANN) and time series data can be used for forecasting methods well. Artificial Neural Network is a method whose working principle is adapted from a mathematical model in humans or biological nerves. Neural networks are characterized by; (1) the pattern of connections between neurons (called architecture), (2) determining the weight of the connection (called training or learning), and (3) the activation function. The research objective was to obtain the best artificial neural network architecture, comparing the two methods of Backpropogation Neural Networks with the Radial Base Function Artificial Neural Network (RBF) method. This research is a research using real data (true experimental). This research was conducted at SMK Harapan Bangsa Kuala, which was obtained from 2015 to 2019. The results showed that for one iteration using the backpropagation method the result was 0,378197657 with a squared error 0.143033468, then the results achieved were not in accordance with the target.</em></p> 2021-05-29T00:00:00+07:00 Copyright (c) 2021 JUKI : Jurnal Komputer dan Informatika https://ioinformatic.org/index.php/JUKI/article/view/41 Sistem Pendukung Keputusan Menentukan Status Karyawan Kontrak Sales Promotion Girl Menjadi Karyawan Tetap dengan Metode Simple Additive Weighting 2021-06-03T18:17:33+07:00 Rudi Hartoyo rudihartoyo91@gmail.com <p><em>In selecting and determining contract employees such as Sales Promotion Girl (SPG) to become permanent employees in a company, it still seems inaccurate, because the assessment and calculation of the results of the test are done manually, so there is a possibility of errors in providing the final results of the selection. Therefore, a Decision Support System was designed that could determine SPG contract employees to become permanent employees who could assist the company in selecting the right employees. Decision Support Systems are part of a computer-based information system that is commonly used to support decision making in an organization or company. This decision support system is designed using the Simple Additive Weighting (SAW) method to calculate the results in determining SPG contract employees to become permanent employees. So, in the process of selecting SPG contract employees to become permanent employees using a decision support system using the SAW method can be done easily and precisely, because it is calculated by a computer system.</em></p> 2021-05-29T00:00:00+07:00 Copyright (c) 2021 JUKI : Jurnal Komputer dan Informatika https://ioinformatic.org/index.php/JUKI/article/view/38 Perancangan Aplikasi Kompresi File Audio dengan Algoritma Aritmetic Coding 2021-05-29T17:12:18+07:00 Nurasyiah nurasyiah1211@gmail.com Information exchange nowadays requires speed in sending information. The speed of this transmission depends on the size of the information. One solution to the above problem is compression. There are lots of data compression methods available today, but in this thesis we will discuss the working principles of the Arithmetic Coding algorithm with an implementation using Visual Basic 6.0. This algorithm performance analysis aims to determine the performance of this algorithm in * .MP3 and * .WAV audio files. In this system there are compression and decompression stages. The compression stage aims to compress the audio file size, while the decompression stage aims to restore the audio file size to its original size. 2021-05-29T00:00:00+07:00 Copyright (c) 2021 https://creativecommons.org/licenses/by-nc-sa/4.0/ https://ioinformatic.org/index.php/JUKI/article/view/43 Sistem Pendukung Keputusan Pembagian Kelas Unggulan Siswa Baru Menggunakan Metode Promethee Pada STM Raksana Medan 2021-06-03T18:04:37+07:00 Junaidi junaidi.budidarma@gmail.com <p><em>Education has a very decisive role, not only for the development and manifestation of individuals but also for the development of a nation and a state. The progress of a culture depends on how that culture recognizes, appreciates, and uses its human resources. This is closely related to the quality of education provided to members of the community. The word decision means choice, namely the choice of two or more possibilities. Decision making is hardly a choice between right and wrong but what often happens is a choice between "almost right" and "maybe wrong". Decision making in an organization is the result of a continuous process of communication and participation from the entire organization. The results of these decisions can be statements that are agreed between alternatives or between procedures to achieve certain goals. However, to be able to determine the best decision, there are several methods that can be used to build a decision support system, one of which is Promethee. The promethee method is included in the Multi Criteria Decision Making (MCDM) group solving or multiple criteria decision making which is a discipline that is very important in making decisions on a problem that has more than one criterion (multicriteria).</em></p> 2021-05-29T00:00:00+07:00 Copyright (c) 2021 JUKI : Jurnal Komputer dan Informatika
