The existing stock is not in accordance with the needs of consumers, the distribution of drugs that are less needed in the stock will cause losses because the drug has expired due to too long stored in the warehouse. Another problem is that obat cannot predict drugs that are needed a lot, to overcome these problems needed a prediction system. These problems can be solved by the decision tree method for the prediction of drug supplies. The concept of the Decision Tree Algorithm is to convert data into decision trees and decision rules. System development with Waterfall model, using PHP programming language, My SQL database, system design using object oriented approach, system testing using Black Box for functionality test, validity testing with rapid miner tools. The result of the development of the system is a prediction of drug sales at pharmacies. The result of black-box testing is that all developed systems work properly. The results of the validity test by comparing the old system with the new system with the rapid miner, using 30 transaction samples the accuracy is 89% which means the system has good performance.</p> 2022-07-01T00:00:00+00:00 ##submission.copyrightStatement## Sistem Pendukung Keputusan Pemilihan Supplier Pada PT. Avo Innovation Technology Dengan Metode Simple Addivite Weighting (SAW) 2022-10-20T07:32:22+00:00 Ahmad Ramadhan Supatman Supatman <p>Subjective decision making can lead to errors in supplier selection. In the selection of suppliers, the OEM (Original Equipment Manufacturing) Department has difficulty in choosing suppliers, because many suppliers have submitted offers of cooperation. Therefore, we need a supplier selection decision support system so that the OEM department can determine the appropriate supplier in purchasing products, services and materials. This decision support system uses the SAW (Simple Additive Weighting) method where this method is used to overcome existing problems, because there are many alternatives and criteria that must be considered in supplier selection such as legality, quality management, production capacity, production quality and innovation. From the tests carried out by comparison through Microsoft Excel and the web-based SAW program at PT Avo Innovation Technology using 13 data suppliers to test system performance. It was concluded from the test that the percentage of system performance was 100%, so that this system could be implemented in the company.</p> 2022-07-01T00:00:00+00:00 ##submission.copyrightStatement## Sistem Pendukung Keputusan Penentuan Tunjangan Pegawai Dengan Metode SAW Studi Kasus ( PT Pos Yogyakarta) 2022-10-20T07:35:52+00:00 Fitriana Rukhiyati <p class="Abstract"><span lang="IN" style="font-size: 11.0pt;">At this time, companies need to think about how to improve employee performance in the midst of today's competition.

Certain agencies and fields want all processes in their offices to be fast and practical, as well as acceptance of internships or practical work. Usually, students who are in their 7th semester are required to take practical work courses or internships. the registration process is not short and time-consuming. Starting from students who apply for internships in the Study Program section, students receive a cover letter for practical work which will be brought to the destination agency. Students will bring a cover letter to the institution they are going to and wait for days or even weeks to find out whether their internship application is accepted or not. This makes students have to go back and forth to check whether the practical job application is accepted or not. This complicated and inefficient application process prompted us to develop an internship registration information system to address this problem. Our research uses the Software Development Life Cycle (SLDC) method or the so-called waterfall model. The system created and developed is websie-based using HTML, MySQL database, PHP programming language and Visual Studio Code as text editor. With this system, it is hoped that it will make it easier for companies or general sub-sectional agencies to notify the practice of accepting internships will be accepted or not.</p> <p>Keywords: Information System, Internship, Waterfall, Website</p> 2022-07-05T07:51:29+00:00 ##submission.copyrightStatement## Perancangan Sistem Pakar Diagnosa Penyakit Otitis Menggunakan Metode Forward Chaining Dan Certainty Factor 2022-07-12T07:54:01+00:00 Muhammad Jufri Deosa Putra Caniago <p><em>The ear is the five senses and is the external organ that most often interacts with external objects, the most common disturbance in the ear organs is an infection in the ear called otitis, otitis is an inflammation that causes an infection in the ear.

Among them are children who play as they please, cannot sit still and listen, like to annoy their friends and make it difficult to concentrate. Diagnosis of hyperactivity or ADHD is usually done by an expert or psychologist. But actually teachers or parents can make early detection of the possibility of ADHD in children by observing children's behavior at school or at home from the way they communicate, interact socially with their peers, and the child's imagination ability. The expert system is a solution to assist teachers and parents in early detection of possible ADHD. The expert system is designed based on responsive web by utilizing the forward chaining method as an inference engine.

In this study, the author tries to provide a network security system solution using Packet Filter Firewall with the router in bridge mode and compares network security systems in other research journals. From the results of the comparison, several series of network security protections are produced, namely changing the proxy to bridge mode, IP address protection, content protection with mangle, Mikrotik device protection, traceroute protection, port scanner protection, Bogon IP protection, and Bruteforce FTP protection. After conducting a series of tests from the results of the network protection setup using the Mikrotik RB 750 in bridge mode, the authors conclude that not all packets that pass through the bridge firewall device can be filtered.

This flood can be happened in flood vulnerable area, can cause disadvantage on the area. Flood can be happened cause high volume of water in river or lake, where the dam or irrigation can no longer accommodate the volume of water. The main causes of flooding are waterways that are blocked by al lot of garbage dumped carelessly by the community, illegal logging which can trigger flooding. Based on these problems, the researchers focus on the water level which during the rainy season. Therefore, the researchers made&nbsp; an IoT based flood detection system using two microcontrollers&nbsp; ultrasonic sensor and water level sensor as a measure of the water leve. </em><em>The IoT-based ultrasonic sensor functions to send water level data which will be displayed by LCD, Blynk Notifications on android smartphones and also Buzzer alarms, and the Water level sensor serves to provide an alarm signal to the buzzer if water has touched the sensor. With the two flood detection tools, it will provide information faster, if the ultrasonic sensor has a signal problem, the water level sensor will give a warning in the form of an alarm on the buzzer when the water touches the sensor. The trial results of this prototype design have worked well to send alarms or signals with notifications on the Blynk application as a flood warning to the public.</em></p> 2022-08-08T02:00:12+00:00 ##submission.copyrightStatement##
