Abstract

Message Queuing Telemetry Transport for Sensor Networks (MQTT-SN) is a publish-subscribe communication protocol for Wireless Sensor Networks (WSN), which developed to guarantee the needed of publish-subscribe protocol which can be applied for sensor networks which doesn't have network interface. However, MQTT-SN has a weakness because by default MQTT-SN sends plaintext in transmission process, it proves that MQTT-SN don't guarantee security aspect of confidentiality. Security mechanism is needed to ensure confidentiality of MQTT-SN especially in its use as a communication protocol in healthcare system, because in health sector data confidentiality is important. Security mechanism to ensure MQTT-SN confidentiality has been conducted using Advanced Encryption Standard 128 (AES128), which is a conventional cryptographic algorithm with high computational process which not appropriate with WSN characteristics, in addition computational defects has been found in all types of AES, so an alternative algorithm is needed to replace AES. This research provides an alternative solution by applying end-to-end security mechanisms for publishers and subscribers using lightweight stream cipher Grain-128 on prototype electrocardiogram monitoring system based on MQTT-SN. The results showed that, this security mechanism successfully secured electrocardiogram data transmitted on MQTT-SN protocol from confidentiality. Grain-128 performs better than AES128 based on encryption time and memory usage.

Abstract

Ineffective waste management is believed to be the reason of the piling amount of waste in landfill. There should be sorting mechanism from the source of waste before being transported to TPA. Offices are of the areas which produce waste similar to household waste and must carry out waste sorting process. Actually, there have been trash cans provided for different waste type. However, people tend to be ignorant of this and keep on throwing waste not in the right container. Thus, the trash can method is rendered ineffective. This study attempted to create a prototype of trash can that classifies office waste in the form of plastic bottles, cans, and paper. The system then automatically places those waste based on their category container. To perform its job of classifying, the deep learning Xception architecture method is used, applied to the system processor, namely the NVIDIA Jetson Nano. This system produces output, namely the movement of the sorting arm. The sorting arm moves to the left if the classification results are plastic bottles waste, it moves to the right for cans waste, and it stays in the middle for paper waste. For testing the classification of waste objects in the system, the accuracy result obtained 91.67% and the average computation time for classification was 0.06385 second. An integration testing was also carried out on the system which resulted in an accuracy of 97.22%.

Abstract

At the beginning of 2020, the Covid-19 pandemic had a detrimental impact on many parties. The tourism sector is one of the sectors that have been disadvantaged by the arrival of Covid-19. Since the presence of Covid-19, many tourist attractions have been closed due to government regulations to limit people from doing activities outside. This has resulted in considerable losses for the owners of tourist attractions due to the reduced number of visitors since the pandemic, one of which is the Lahor tourist spot. Visitors to Lahor's tourist attractions are increasingly deserted and have experienced a decline in turnover of more than 50%. With the hope of helping tourism managers in re-promoting Lahor tourist attractions, the author designed a user experience application for promoting Lahor tourist attractions during the pandemic using the design thinking method so that people can travel virtually at Lahor tourist attractions and visit them in person in the future. The author uses the design thinking method because based on existing research, design thinking is able to produce innovative solutions to problems. This study provides the final result in the form of a high-fidelity prototype. This test uses usability testing to test aspects of effectiveness, aspects of efficiency, and aspects of user satisfaction. From the results of the tests carried out, the design of this application solution got a score of 99% effectiveness aspect, 0.0868 goals/sec efficiency aspect, and 91% user satisfaction aspect. Based on the results of the System Usability Scale, the design solution for the Visit Lahor application is in the Grade A category, adjective rating excellent, and in the acceptable category.

Abstract

In field of information technology education, provisioning virtual lab is very important to provide practical experience to learners. This has made many universities develop their own virtual labs. However, in practice, each university can have limited or excess of resources. This makes the existing virtual lab run inefficiently. This research proposes the implementation of virtual lab based on multi-cluster container technology with Kubernetes orchestrator to create virtual lab system that allows universities to share resources. The implementation of the virtual lab system is carried out by implementing three main components: orchestrator cluster, university cluster, the Rancher multi-cluster management platform as the university cluster controller. The functional evaluation results in adding new university clusters, displaying university clusters information, running container applications, exposing application within the cluster to outside of the cluster, adding new users, managing access rights of these users, and manages the resource usage of the running container are all well-functioning. The non-functional test results shows that the system can handle requests from 1000 users simultaneously with 32.84% CPU and 77.60% Memory utilization. Meanwhile, when handling 10000 users, the system can handle 79.5% of the total requests with 83.18% CPU and 77.06% Memory utilization. From the test results, the system in this study is proven to have good scalability to handle access by many learners and can be a solution for a container-based virtual lab system.

Abstract

One of the successes in cultivating BSF (Black Soldier Fly) maggots is influenced by the quality of the environment that must remain ideal, namely temperature and humidity. But this is still rarely known so that it is one of the factors causing the failure to cultivate BSF maggots. Therefore, the monitoring and control system on the BSF maggot cage can be a solution to this problem. The telegram application serves as a media viewer of the designed system. Monitoring serves to get the latest information about the temperature and humidity in the BSF maggot cage, while the control system is designed to determine the active actuator according to the conditions in the BSF maggot cage to remain ideal using the fuzzy logic Mamdani method. From the test results it is concluded that the system can work according to its functions. Telegram bots can provide feedback according to commands sent by users with a response time of 2 seconds. The accuracy of the DHT22 sensor in temperature sensing is 99.16% while the accuracy in humidity sensing is 95.31%. The implementation of fuzzy logic in the system can make the quality of the BSF maggot environment remain ideal and can determine the active actuator according to the conditions on the BSF maggot cage with accuracy to the lamp defuzzification output of 99.89% and the accuracy to the mist maker and fan defuzzification output of 98.66%.

Abstract

Video games that are played online require a gaming device to be linked to the internet in order to function. Online games that may be played on a mobile device are among the most accessible. In digital games, the display—also known as the game interface—allows players to interact with the game. The interface of the game contains every sign, text, image, and hint. The developer must assess the produced interface in order to obtain a nice interface. Cognitive walkthrough is one of the analytical techniques that may be used to assess the usability of the user interface. Three versions of Cognitive Walkthrough are available The cognitive idea that the individual doing the evaluation must possess is highlighted in the first version. Because it is extremely complicated and time-consuming, the second version can be viewed as a failure. Preparation, analysis, and follow-up are the three stages in the third iteration of Cognitive Walkthrough. Both of the respondents—two individuals—had never played the mobile phone game. The respondents' findings will then be tabulated and presented in a table with an explanation to help with a more in-depth understanding. The responses included individuals in elementary school, junior high school, high school, college, and even those who were already employed.
