College student activities are created and organized by them through College Student Organizations and student activity units. The implementation of college student organization activities at Madura University has several obstacles. These obstacles generally occur because the service process is still manual and has not been recorded digitally. This makes it difficult for student coaches to find data on student organization activities and student activity units. With this information system, management data, activity proposals, accountability reports, student funds and documentation of activities organized by student organizations will be recorded digitally. The results of the User Acceptance Test on 40 student organization administrators presented the percentage of responses related to user satisfaction was 73.25% based on the score interpretation criteria on the Likert scale. This presented that the response related to user satisfaction with the system built is strong and according to needs.

However, in reality preparations for the selection of prospective recipients of student aid funds are still being carried out with the criteria and readiness for what the status is. The problem is not right on target for the recipient. So, it is necessary to design a Decision Support System (DSS) to run this program as well as possible. This research uses a type of research model, namely Multi Criteria Decision Making (MCDM) which prioritizes assessment based on the desired criteria. The assessment criteria include: the income of the guardian of the santri in one month, the burden of family costs in one month, the number of relatives, and the length of time in line. To determine the weighting of the criteria using the Technique for Others Reference by Similarity to Ideal Solution (TOPSIS) method.

In order to tackle congregational issues with attendance, this research was done in order to design and develop an Android-based church attendance application. This system was designed and developed using the RAD (Rapid Application Development) methodology. The author created the program "Android-Based Attendance Application for the Indonesian Christian Church Gading Serpong" based on an examination of the attendance procedure for the congregation that meets at GKI Gading Serpong. Making this application is in line with the research's goals to reduce the need for actual church cards, solve the issue of lost or damaged church cards, make it simpler for the congregation to view the schedule of events, and assist in reminding the congregation about future events. The number of Paths with the results of calculations using the formula is produced using whitebox testing, and the results are the same. This can be interpreted that there is no error code contained in the program. The results of the interviews were taken from 20 people who filled out the questionnaire. From these respondents, 93% answered yes or agreed that this application could be used properly. Based on the results of these respondents, that respondents can feel the benefits of this application in minimizing the loss or damage of church cards and getting information they can use this application to carry out attendance, view activity schedules, and receive notifications about activities.</em></p> 2022-11-01T06:03:29+00:00 Copyright (c) 2022 Antivirus : Jurnal Ilmiah Teknik Informatika https://ejournal.unisbablitar.ac.id/index.php/antivirus/article/view/2425 WEB BASED APPLICATION DESIGN IN UNIRA CLINIC FOR SERVICE OPTIMIZATION 2022-11-25T07:24:58+00:00 Abd.

The analysis was carried out by measuring the conditions of temperature, air humidity and soil moisture without using automatic environmental temperature and humidity control devices.

In this study used temperature and humidity sensors </em><em>air DHT11, soil moisture sensor YL 69. The sensor is connected to the Arduino UNO microcontroller to carry out commands to the sprayer and fan. Before designing an automation system, an analysis is carried out on the range of fans and sprayers used. From the analysis carried out, the greenhouse area is divided into 8 measurement lines. Based on the research that has been done, it can be concluded that by using automatic temperature and humidity control devices for air and soil, the distribution of temperature and humidity becomes more pronounced, the resulting microclimate can support plant growth. Before the automation, the distribution of the greenhouse microclimate was not evenly distributed at every point and every time, whereas after the automation, the distribution became even.

Government assistance funds for agriculture are distrbuted from the District Agriculture and Food Security Service to Farmer Groups. Then, the Farmers Group will distribute the funds to the farmers. The distribution of funds from Farmer Groups to farmers has the potential for fraud. This is due to the lack of monitoring by the local government in the process of distribution funds from Farmer Groups to farmers. From the description of the problem of distribution funds by farmer groups, it is necessary to design a system for the distribution and use of aid funds for farmer groups.

Based on this background, this research is intended to apply machine learning developed from the OpenCV and MediaPipe libraries to carry out the process of training and testing finger gestures as gestures to control one of the functions in Windows, one of which is volume control.
