Abstract

A multi-sensor system that runs simultaneously is a factor to be considered when building a multi-sensor system. In order for the system to run simultaneously required a system with a fast response. By applying multitasking then the system can execute more than one program simultaneously. RTOS (Real Time Operating System) is one method for multitasking application on embedded system. To implement RTOS into Arduino requires FreeRTOS library. Arduino Mega 2560 Microcontroller and HC-SR04 sensor module as much 8. Communication interface on this system using Parallel Bus Interface (PBI) to support performance in multisensor system running simultaneously. In the application of RTOS this system will be divided into 8 tasks. Each task will process each of the HC-SR04 sensor modules. From the results of performance testing HC-SR04 sensor module gain percentage error of 0% of all sensors. For testing the execution time stability of each task is 1ms on each task in 10 experiments. From the test results, the system that runs the RTOS running from the beginning of the program to the end requires a total time of 8.1332ms average while on systems that do not implement RTOS requires a total time average of 264ms. Each task has an execution time ranging from 1.005 to 1.583ms.

Abstract

The Message Queuing Telemetry Protocol (MQTT) protocol is one of the IoT protocol which has a mechanism based on topic-based publish-subscribed systems that have properties that are suitable to be implemented on devices that have limited resources. This is due to it has light-weight properties. MQTT is one of the protocols that is often used on IoT, but there are several weaknesses in the security issues. To ensure the data security an algorithm is needed to encrypt data. One of security algorithm for encrypting data is the Lightweight Stream Cipher for Power-constrained Devices (Lizard) algorithm. In the publisher section before the message is sent it will be encrypted (ciphertext). In broker the ciphertext will forward to the subscriber. In the subscriber, the message will be decrypted. Based on the test results, the Lizard algorithm implemented in the MQTT protocol successfully secure a system on NodeMCU device that take 1014419 microsecond.

Abstract

Automated source code evaluation system is a system used to examine a program, in fact its research has been around since 1965. As technology grows, more and more people use Docker to create this system. By using Docker, system will be isolated so it can make computer safe. That's why the automated evaluation system in this study uses Docker to make sure the computer is safe. Even though the system can run safely, there are still some problems occurred on the automated system. The problem is how to make the evaluation process efficient and less burdening the computer and how to speed up the evaluation process if there is a program that takes a long time to be evaluated. Therefore, this research will make a cluster of automated source code evaluation system. In this cluster, there will be two instances, a master that divides the task and slaves that run the evaluation. Master and slaves will be connected with RPC because master will only call a function on the slave. The division of tasks will use round-robin algorithm, where slaves will be selected interchangeably. The test results show that this cluster capable of evaluating programs and able to evaluate up to 104 programs at once. In addition, this cluster can also divide the task efficiently so it can reduce the burdens on the computer and speed up the evaluation if the program takes a long time to be evaluated.

Abstract

The growth of the gaming industry started from the development of 2-dimensional games. But in its development, 2-dimensional game began to lose with 3-dimensional game. While 2-dimensional games have the advantages i.e. the development cost is cheaper and the development time is shorter than the 3-dimensional game. Adding real-time dynamics lighting and soft shadow methods is expected to increase the value of the two-dimensional game itself. Therefore in this project is implemented by the method in 2-dimensional game environment with case study of Game Wipe-It-Off. Real-time dynamics lighting and soft shadow methods are implemented using OpenGL Graphic API, C ++ Language, and GLSL. From performance testing obtained information about frame rate, frame time, CPU usage, and memory usage in game using method and not using method has not significant difference. So it does not affect much the performance of the game. Therefore the use of such methods is highly recommended to add value of the game without having to sacrifice game performance. In addition, the implementation of the method there is no indication of a memory leak, where the use of memory has a stable value with the difference between the largest and the smallest memory usage is 790528 bytes.
