Abstract

Coronavirus disease 2019 or COVID-19 caused by SARS CoV 2 is a tragedy in the world of global health. Even the World Health Organization (WHO) has stated that the corona virus outbreak is a Public Health Emergency of International Concern (PHEIC) or an international public health emergency. Not only has an impact on health but this virus outbreak also has a major impact in various sectors such as disruption of the country's economy, obstruction of the teaching and learning process and so on. This impact is caused by the rapid spread of the virus. Therefore, the authors designed a monitoring and screening application for COVID-19 using certainty factor and forward chaining methods which aim to make it easier for people to monitor the spread of the COVID-19 virus in real time and be able to carry out early screening for COVID-19. Both of these methods produce a system diagnosis with the same results, that is, someone is indicated as SUSPECT COVID-19.

Abstract

Seiring dengan berkembangnya teknologi yang semakin pesat, pembuatan sistem informasi guna menunjang pekerjaan pun semakin diperlukan. Namun, dalam penerapannya tidak selalu memberikan manfaat yang optimal bagi penggunanya. Sehingga diperlukan evaluasi terhadap sistem informasi yang telah dibuat. Perancangan sistem pendukung keputusan yang memberikan kesimpulan berupa ”Puas” dan ”Tidak Puas” dapat dijadikan sebagai bahan evaluasi dan perbaikan. Penelitian ini bertujuan untuk membantu mengukur efektivitas sistem informasi melalui sistem pendukung keputusan yang menggunakan metode Naive Bayes Classifier. Metode tersebut dipilih karena mampu melakukan proses klasifikasi berdasarkan data terdahulu untuk memprediksi data mendatang. Dari hasil pengujian yang dilakukan menggunakan data latih sebanyak 100 data dan data uji sebanyak 55 data, nilai akurasinya sebesar 85.45% dan error sebesar 14.55%.

Abstract

The rose is a plant from the genus Rosa which has more than 100 species with various colors. In the process of selecting roses, you will find roses that are still fresh and wilted. With that, we can detect the wilting of the rose by applying the HSI and HSV methods to image processing applications, the data collection process, namely by making data preparations on the Kaggle dataset, then classifying and training the data using the HSI and HSV methods. Based on the classification results of a total of 820 images of rose images, a total of 757 images were tested using HSI and HSV. The values obtained were Range at HSI, H = 0–0.5, S = 0–1, and I = 0.5372549–1 in the Fresh category, while the category HSI wilt, H = 0–0.5, S = 0-1, I = 0.5620915–1. The HSV range values are in the Fresh category H = 0–0.5, S = 0-1, V = 0-1, and the Wilt category H = 0-0.5, S = 0-1, V = 0-1. Furthermore, the success rate for testing roses with HSI reached 92.3% where the data read correctly 757 and read incorrectly 63 out of 820 sample data of roses, while testing on HSV the success rate reached 93.2% where the data read correctly 765 and read incorrectly 55 out of 820 rose flower sample data. Based on the above results, detection of wilting roses using the HSV color space transformation method is the best in data testing.

Abstract

FSA abstract machine (Finite State Automata) is a machine that is only seen from logic and processes and can use various programming languages to make it. The FSA Abstract Engine is accepting and rejecting an input. FSA is divided into two namely, DFA (Deterministic Finite Automata) and NFA (Non-deterministic Finite Automata). This paper discusses the use of the FSA algorithm to create DFA and NFA abstract machines based on Android. By using an android-based FSA abstract engine application the user can determine the input results of the automata process accepted or rejected easily and accurately without having to do manual calculations.

Abstract

Monitoring systems are a rapidly increasing need in almost all lines of public, such as roads, parks, buildings, terminals and many places that have a monitoring system. Detection adapts learning of moving objects in video observation to obtain results such as the human sense of sight. By detecting objects in the monitoring system, we can determine the frame that shows the position of the moving object. The methods that can be used to de-tect objects are background subtraction and morphology, these methods are considered appro-priate to be implemented in the designed program. The research method used is divided into two stages, namely data collection to collect CCTV video samples and search for related research references. Then the stages that the program goes through include frame extraction, implemen-tation of background subtraction, conversion of grayscale images and converting them into bi-nary form, performing opening morphological operations, making masking and implementing them into video. From the test results the program has a success rate of 93.3% of the test with bright lighting and 83.3% of the test with dim lighting.

Abstract

In this increasingly modern era, technology has become a must in improving performance in every organization and various other activities. One example of the application of technology that will be explained in this research is the design of a web-based e-voting system in the election of Abang None Jakarta by inserting an E-KTP numbers to be able to cast a vote in the election. Previously, the selection of Abang None Jakarta still uses SMS voting system that is considered to be less effective because the use of credits is considered more wasteful than the use of internet quota. In developing this web-based e-voting system, the researcher uses the SDLC (System Development Life Cycle) method and the Caesar Cipher algorithm method for voter data security. Besides that, the Gateaway SMS system is used to prevent any voter who uses someone else's E-KTP before casting a vote in an election. The e-voting system is made using the PHP and Xampp programming languages as its database. The e-voting system is expected to be used in making a transparent decision, speeding up the voting counting process, saving costs and preventing fraud when implementing e-voting in the election of Abang None Jakarta. The results of research is proven successful in terms of both the use of the web to conduct the election and the use of security in encryption and decryption of user data.

Abstract

Currently, there are so many game engines that can be used to design and create games. One of them is Unity 3D. It is now a game engine widely used not only by a person to design or create games but also by some developers to produce games. Collision Detector Algorithm is a method of detecting reaction produced by a collision between two or more objects. The method is primarily used in the animation and game production. The researcher uses this method to design a driving simulation game, in which a player hitting obstacles that have been stacked on a track will experience reaction from one of the specified obstacles. From the results of this study, it can be concluded that the Fps obtained in this game reaches its best point at around 60 Frame Per Second and its worst point at around 24.6 Frame Per Second.
