Abstract

Test of English for International Communication (TOEIC) is a compulsory subject taught to all students regardless their chosen concentration. The subject covering the consecutive two semesters at Institut Bisnis dan Teknologi Bina Sarana Global has been given for the past five years. Nevertheless, the students’ achievement is still considered low, where the average scores for both mid and final semester paper-test based haven’t met the expected target. TOEIC itself tests students’ ability to comprehend reading texts encompassing grammar, sentence structure and vocabulary. This becomes a challenge since the majority of students have below average English competence. In contrast, their access to technology is deemed adequate, thus, its implementation towards learning can be a contributing factor to a better learning outcome by providing engagement with the technology itself. In line with the development of technology and to accommodate students’ learning needs with various motivation and abilities, a scheme for developing learning materials through a web design was proposed. The researchers used SLDC for the design method, focusing on prototyping model through phases from generating users’ needs, designing prototype using figma application, putting into trials and practices to conducting evaluation. As for the application, a PHP programming language with Codeigniter 4, programming MySQL as a database system, Bootsrap for website outlook, Black Box Testing with Equivalence Partitions Technique and Beta Testing through questionnaire become the framework for the proposed design. After the implementation was completed, a good result with a percentage of 71% for the usability of the application was shown and that students achieved better scores in the given practice tests.

Abstract

The Caringin Banten Mosque is a historic relic that must be preserved and introduced to the public, but the condition of the historic mosque in Banten is no longer visible, therefore digitalization is needed so that people can know the historical events of the mosque. The technology that can be used to digitize the mosque building is Virtual Reality, which is a technology that allows users to see and interact with an environment that is simulated by a computer, so that users feel they are in that environment. Virtual Reality can be applied to various devices, one of which is currently widely used, namely Android. The purpose of this research is to produce a Virtual Reality application for the Caringin Banten Mosque based on an Android smartphone, with the hope of making it easier for the public to know and learn about the historical heritage of the Caringin Banten Mosque. This research method uses the Waterfall model from the SDLC. The stages are divided into 6 namely: System modeling, Software requirements analysis, Design, Coding, Testing and Maintenance. The author uses Blender software to create three-dimensional objects, then uses Unity software to create virtual reality applications. Based on testing, the application can run smoothly on the author's Android device. However, when tested by 10 (ten) people, the application still has some shortcomings. However, the application was successful in introducing the Caringin Banten Mosque to users.

Abstract

In this increasingly advanced era, Information Technology (IT) is unavoidable. Everyone is competing to find innovations that can improve their performance. Private Universities (PTS) in Indonesia are no exception. An educational institution's attendance list is the primary reference in monitoring student activities. Although this sector is critical, traditional data collection is still taking place. As a result, many problems arise, such as data loss, long charging times, long queues, overcrowding, and even affects student concentration. ITS NU Kalimantan is one of several private universities in Central Kalimantan and is still relatively new. Student attendance applications are designed and developed for more mature data collection to avoid problems that arise later. This study offers the use of web android-based technology equipped with a QR code feature. Based on the questionnaire results conducted on 45 respondents who used the UAT model, the perceived usefulness aspect was 82%, the perceived ease of use aspect was 84%, the perceived user acceptance aspect was 82%, and the average rating produced was 83%. This percentage shows that users respond positively to this attendance system.

Abstract

In this research, a system has been designed that aims to prevent water wastage every time you fill a water reservoir. The design of the system is in the form of filling and monitoring automatic water reservoirs that go through 5 stages, namely tool prototype design, prototype making, making a series of tools, measuring and analyzing data. This tool utilizes the HC-SR04 sensor which will detect the water level in the water reservoir if the water level is 1-23 cm then the water reservoir is filled automatically and when the sensor distance from the water is 20 cm then the water reservoir will not be refilled. In designing this system using a NodeMCU ESP8266 microcontroller and the MQTT protocol which will run the control process on the system and process input data from sensors. The output will be displayed on the LCD (Liquid Crystal Display), MQTT Dash and Node-Red Dashboard in the form of the water level in the reservoir. The added relay functions as an automatic switch when turning off and turning on the water flowing in the reservoir. This can reduce the use of water as a medium for ablution that is wasted so that it becomes more effective and efficient.

Abstract

The data on heart disease patients obtained from the Ministry of Health of the Republic of Indonesia in 2020 explains that heart disease has increased every year and ranks as the highest cause of death in Indonesia, especially at productive ages. If people with heart disease are not treated properly, then in their effective period a patient can experience death more quickly. Thus, a predictive model that is able to help medical personnel solve health problems is built. This study employed the Random Forest and Decision Tree algorithm classification process by processing cardiac patient data to create a predictive model and based on the data obtained, showing that the data on heart disease was not balanced. Thus, to overcome the imbalance, an oversampling technique was carried out using ADASYN and SMOTE. This study proved that the performance of the ADASYN and SMOTE oversampling techniques on the C45 algorithm and the Random Forest Classifier had a significant effect on the prediction results. The usage of oversampling techniques to analyze data aims to handle unbalanced datasets, and the confusion matrix is used for testing Precision, Recall, and F1-SCORE, as well as Accuracy. Based on the results of research that has been carried out with the K-Fold 10 testing technique and oversampling technique, SMOTE + RF is one of the best oversampling techniques which has a greater Accuracy of 93.58% compared to Random Forest without SMOTE of 90.51% and SMOTE + ADASYN of 93.55%. The application of the SMOTE technique was proven to be able to overcome the problem of data imbalance and get better classification results than the application of the ADASYN technique.

Abstract

The development of technology in recent years has been very rapid, there are still many people who use short message technology, but the security aspect is not guaranteed. People who exchange information are at risk of having information content theft during the delivery process, for that it is necessary to encrypt messages before sending and decrypt them to be read so that they are not easily misused by unauthorized people. With Rivest Cipher 6 and Blowfish cryptographic algorithms, this model is a symmetric key algorithm in the form of a block cipher that can answer message security. This method is suitable for maintaining message security. In this paper, a number of aspects of cryptography will be discussed as well as the basic concepts of cryptography. The purpose of the application is designed to be able to implement the Rivest Ciper 6 and Blowfish algorithms. Rivest Chiper 6 and Blowfish algorithms implemented on android smartphones can encrypt messages before they are sent and decrypt messages when they are received, by using two message security encryption options, users can distinguish the results of the two algorithms and become more secure. In the encryption and decryption process, a key is needed to scramble and restore the contents of the message. The key is obtained when the sender and recipient met previously can also send the key through the application, but the key sent will be immediately deleted by the application so that others do not know the key to open the message.

Abstract

Vaccination is the administration of vaccines to a living being to stimulate the formation of an immune system against a virus, while mass vaccination is the simultaneous administration of vaccines to a group in the form of organizations, companies, or the wider community to create herd immunity. However, with the limited number of vaccines available, it is not possible to carry out a thorough vaccination of a group with a very large number of members. It requires determining in advance who will be prioritized for the vaccine. The purpose of this study is to build a system that can automatically determine vaccination priorities to be more effective and efficient by implementing a decision support system using the Analytical Hierarchy Process (AHP) method and the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS). The result of this study is the formation of a Web-based decision support system application that produces the output of alternative ranking sequences as objects that will be prioritized for vaccines based on calculations against predetermined criteria.
