The main focus for the determining potential recipients of education assistance funds is the accuracy of targeting the recipients. Many students with middle to lower economic status are the main reason for delaying the payment of sharia obligations. 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. Thus, the results of research that have been carried out using the TOPSIS method in determining prospective recipients of student educational assistance funds based on the criteria determined by the results of the preference value A1 with a value of 1 ranking 1, A2 with a value of 0.7913 ranking 2, A3 with a value of 0.6125 ranking 3.</em></p> Moh Mufarijul Hammi Latipah Achmad Muchayan Copyright (c) 2022 Antivirus : Jurnal Ilmiah Teknik Informatika 2022-09-09 2022-09-09 16 2 108 121 10.35457/antivirus.v16i2.2281 TOURISM BUS INCOME PREDICTION USING THE LEAST SQUARE METHOD <p>Tourism is one of the fields in Indonesia that is engaged in serving foreign tourists and domestic tourists who visit tourist objects in Indonesia.

The problem that occurs is the uneven distribution of air and soil temperature and humidity in all greenhouse areas which will ultimately affect plant growth in that area. This can be overcome by adding smart devices to the greenhouse</em><strong>. </strong><em>Analysis of temperature and humidity in the greenhouse aims to maximize the microclimate for plant growth. 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. Then an analysis of environmental conditions is carried out by adding sensors and adding sprayers and fans connected to sensors measuring soil and air temperature and humidity. 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. Optimization can be done even better if you pay attention to the needs of plants based on the type of plant being cultivated.</em></p> Kurnia Paranita Kartika Rianti Yogi Prastyo Copyright (c) 2022 Antivirus : Jurnal Ilmiah Teknik Informatika 2022-11-24 2022-11-24 16 2 200 210 10.35457/antivirus.v16i2.2512 DESIGN SYSTEM MONITORING FOR ASSISTANCE FUND FOR FARMERS USING WATERFALL AND MODELLING VIEW CONTROLLER (MVC) <p><em>Design is important in the process of developing a system. With the design process, we can design the needs of a system according to the specifications of the user's needs. The result of design process will later be used as a guideline in the system implementation stages. The problem raised in this study is the process of monitoring aid funds for farmer groups in Bojonegoro District. 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. For the system development process use the waterfall development method. The waterfall approach was chosen because the waterfall method is carried out in stages and has good system development documents at each stage. With the waterfall method, the design process can be carried out in-depth because there is no overlap with other processes. The results of this study are in the form of design artifacts which include use case diagrams, activity diagrams, system architecture, class diagrams, database design, and interface design.</em></p> Fawwaz Ali Akbar Budi Nugroho Annisaa Sri Indrawanti Copyright (c) 2022 Antivirus : Jurnal Ilmiah Teknik Informatika 2022-11-24 2022-11-24 16 2 211 222 10.35457/antivirus.v16i2.2489 FINGER GESTURE RECOGNITION TO CONTROL VOLUME ON COMPUTER USING OPENCV AND MEDIAPIPE LIBRARY <p><em>Gesture recognition is a part of artificial intelligence in the field of computer vision. With gesture recognition, the computer is able to understand the movements captured on the camera/webcam. The benefits of gesture recognition are many, one of which is what researchers are doing regarding hand-tracking gesture recognition of the human right-hand finger to adjust the volume control on a computer or laptop. 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. This process uses the OpenCV Library and MediaPipe because they are capable of multiprocessing with real-time data, so the gesture identification process is faster and more accurate. When the camera/webcam captures the frame of the movement of the human's right-hand finger gesture, an augmentation process is carried out and the provision of keypoint localization landmarks is carried out for each knuckle. In this study, only the fingertip landmarks and index finger landmarks were recognized. Machine learning will perform calculations from the distance between the tip of the thumb and the tip of the forefinger which is used to determine changes in the volume of the sound. From the test results of nine trials with different finger poses, 88.89% was obtained. One of the test results failed to read finger movement gestures, due to the landmark position of the tip of the index finger which was closed with the other fingers.</em></p> Saiful Nur Budiman Sri Lestanti Suji Marselius Evvandri Rahma Kartika Putri Copyright (c) 2022 Antivirus : Jurnal Ilmiah Teknik Informatika 2022-11-25 2022-11-25 16 2 223 232 10.35457/antivirus.v16i2.2508
