To overcome this problem the drug sales information system is a solution to the drug sales process, and uses the Click to Chat API Whatsapp to facilitate sending messages to drug suppliers. To obtain the data needed during the study, the author uses several method including: interviews, observation, and literature studies. The data obtained then analyzes using the Waterfall method. The results of this study conducted on testing sales applications that have been designed can help to facilitate managers in the sales process that can be accessed online so that it can work effectively and efficiently. With the Click to Chat feature Whatsapp can facilitate messages to drug suppliers according to the contact you want to reach. The results of this study are expected to be useful in the future.</em></p> 2021-11-05T00:00:00+07:00 Copyright (c) 2019 JUSS (Jurnal Sains dan Sistem Informasi) https://online-journal.unja.ac.id/JUSS/article/view/8449 Prediksi Indeks Harga Saham Gabungan (IHSG) Menggunakan Algoritma Autoregressive Integrated Moving Average (ARIMA) 2019-12-31T15:59:01+07:00 Ulfa Khaira ulfa.ilkom@gmail.com Pradita Eko Prasetyo Utomo pradita.eko@unja.ac.id Tri Suratno trie123@gmail.com Pikir Claudia Septiani Gulo pikirclaudia33@gmail.com <p><em>There are various types of investment </em><em>in Indonesia, one of which is the Indeks Harga Saham Gabungan (IHSG) or in English it is called the Indonesia Composite Index, ICI, or IDX Composite.

This study aims to predict the price of the IHSG </em><em>with data mining techniques using an algorithm that can be used as a reference for investors when making an investment.

Aspects that need to be considered in hotspots to make users feel comfortable is security then at the provider side, the aspect that needs to be considered is the regulation of bandwidth allocation to optimize the data transfer speeds that the network and to prevent the possibility of dense network traffic. RADIUS server is one type of server that can be used at hotspots to secure hotspots because it supports various types of encryption. In this study, optimization of the settings for hotspot network bandwidth is optimized by integrating the RADIUS server with RouterOS. Bandwidth allocation management is done by determining the active time of a user account and set quotas hotspot uploads and downloads for the account. The results obtained from this study indicate that when a hotspot user account has passed the active time or has passed the upload quota and the download given, the account will be deleted from the list of hotspot user accounts or disabled.</em></p> 2021-11-05T00:00:00+07:00 Copyright (c) 2019 JUSS (Jurnal Sains dan Sistem Informasi) https://online-journal.unja.ac.id/JUSS/article/view/8409 Korelasi Antara Fixation Eye Tracking Metric dengan Performance Measurement Usability Testing 2019-12-31T15:59:02+07:00 Yogie Ajie Purnomo yogiaji130297@gmail.com Tri Suratno trie123@gmail.com Mauladi Mauladi mauladi@unja.ac.id <p><em>Not all websites have fulfilled basic principles such as accessible and easy to use (usa</em><em>ble</em><em>).

This model is the most widely applied and found on e-commerce sites in Indonesia. The Customer-To Customer (C2C) market is currently still dominant in Indonesia's online retail market. Data collected from Euromonitor estimates that the C2C market contributed 3% of the retail market in Indonesia in 2017, while the B2C market contributed 1.7%. One text mining analysis is that sentiment analysis can be applied to companies that issue a product or service and provide services to receive opinions (feedback) from consumers for the product. Sentiment analysis is applied to classify positive, negative, and neutral feedback from consumers so as to speed up and simplify the company's task to review their product deficiencies. The researcher conducted further analysis on Bukalapak user reviews to find out how user comments or opinions were on Bukalapak using the TF-IDF Algorithm method. And it can be concluded that based on customer review reviews in Bukalapak have a good rating or perception of this Vans shoe product. Can be seen from the results of Sentiments, Sentiment Visualization and WordCloud Visualization which shows that positive reviews have a higher frequency of 70%.</em></p> <p><em>&nbsp;</em></p> 2021-11-05T00:00:00+07:00 Copyright (c) 2019 JUSS (Jurnal Sains dan Sistem Informasi)
