Abstract

Arduino devices with ATmega328 microprocessors and NRF24 radio modules can be used as a wireless chat communication devices. Data communication by NRF24 is generally unencrypted, so chat communication is not secure. There are various encryption algorithms that can be used, but not all encryption algorithms are suitable for ATmega328 because of limitations. ATmega328 microprocessor has very limited computational capability, making it less suitable if the encryption process is performed using an algorithm with a high level of computational complexity. Vernam Cipher is an algorithm that uses simple calculations with XOR. Three-Pass Protocol is a simple data transmission protocol that can be used to secure the distribution of encryption keys. In this study, the Vernam Cipher algorithm and Three-Pass Protocol are combined to secure chat data. Chat data that can be secured in this study are text, images, video and audio. From the test results of 10 times on sending chat data, obtained test results with 100% percentage that the system can secure chat data. From the test results, the average time for the encryption process 16 character strings with the Vernam Cipher algorithm on the ATmega328 is 1.9 millisecond.

Abstract

A cluster computer is a type of parallel or distributed processing system that consists of a collection of stand-alone computers that are connected and work together as one integrated resource (Morrrison, 2003). Cluster computers can be implemented for specific purposes, and using parallel processing methods such as MPI4PY (Message Passing Interface for Python) MPI4PY is used to execute parallel programs into subtasks, then send them to the cluster nodes for processing. This research focuses on designing, implementing, and knowing the performance produced by computer clusters using raspberry pi 3. To find out the resulting performance, a scheme is tested using a master node without a slave, one slave master node, two slave master nodes, and a master node. three slaves. The monitoring process is carried out using ganglia to determine the size of cluster resource usage. The monitoring results show the highest memory usages of 818.8M in 109 iterations of testing the master node and 2 slave nodes. The highest loads/process was 14.1 in 109 iterations of testing using only the master node. The highest CPU usages were 32.7% in iteration 109 tests the master node and 2 slave nodes.

Abstract

Apple fruit is one of the many types of fruit that has many benefits including preventing disease, nourishing the body and can lose weight. In general, some apple sellers are still unable to distinguish in the selection of apples with the right maturity level, while the human accuracy is not all the same. Everyone has different perceptions in making assessments. Also not everyone has a sharp sense of vision to color. Therefore, a study was made on a system that can classify the level of maturity of apples using the naive Bayes method. This method is a method that is quite good in classifying because the classes to be used are predetermined. In this study, the apple used was Rome Beauty. The level of maturity based on color and weight can be divided into three, namely raw green and ripe reddish yellow and foul yellow cloudy. The sensor readings are processed on the Arduino Uno microcontroller. The results obtained from this study are the level of accuracy on the load cell weight sensor of 96.09% and the level of accuracy on the color sensor of 96.67%. Also obtained the level of accuracy of the calculation of the naive Bayes classification of 100% and the system execution time with an average of 0.725 seconds.

Abstract

The writer research is focused on the topic of moving block signalling system in the railways system. Where this system is proposed to be applied outside of an urban city or a sterilized railways network from it's surrounding. The writer intended to enhanced the already existing research based on the RFID which can provided the necessary information for tracking the position of a train and at the same time calculate the speed of that train so it can be sent to the control center with MQTT protocol. The prototype of this control center itself is designed to be a MQTT broker and scaled down system of the operation control center (OCC). The control center can receive information about the surrounding railway tracks environment with the wayside unit which has been designed to sense an object with an infrared sensor and detecting the vibration of the train by using an accelerometer sensor. This research can provide a prospect for an integrated sensing system about it surrounding environments to be implemented in the signalling aspect of a train. Because the main reason that the moving block signalling system can't be implemented in the rural or suburban area is due to the railway tracks is still intersect with the main road or doesn't have a wall to limit the activities in the tracks area. After finishing this research, the writer can conclude that this prototype of moving block signalling system can be implemented in a smaller scale with a delay around 0.4 - 1.1 second for each received and sended information by the system in the same 802.11 network and access point. This value can provide a glimpse to scale this research in the near future so it can be adjusted to each perspective railway tracks environment.

Abstract

The waste of wealth that is owned by the desire to spend it on needs which causes the behavior of a consumptive lifestyle. (C. Lyons, 2004) argues that early education on money management and savings is beneficial for people who will form intelligence and intellectual characteristics in money management as an adult. Therefore, an effective way to avoid this behavior is to save money so that children can achieve financial success in the future. The existence of this problem encourages the author to realize a solution so that it can encourage children to save by making IoT (Internet of Things) -based piggy banks. This smart piggy bank can detect both types of money (metal and paper) by utilizing the TCS3200 sensor as an RGB color detector for money and a loadcell sensor as a sensor to weigh the weight of money. The infrared sensor is also used to detect objects entering from the piggy bank hole. The features used for this implementation will be classified using an Artificial Neural Network (ANN) classification algorithm. MQTT protocol is used to implement an IoT-based system to display the result of the classification from the system to an android application. The training data that used in the study were 96 data. The TCS3200 sensor tested has an accuracy rate of 93.93% and the loadcell HX71 sensor tested has an accuracy rate of 99.61%. Also, testing with the ANN method which was tested on 24 test data showed an accuracy rate of 91.7%. Meanwhile, the time test in determining the nominal class of 10 tests obtained an average value of 13,48 milliseconds.

Abstract

Tuning is the process of improving the performance of the database to achieve specific goals.. With the tuning process that is usually done by a database administrator still manually, the more time it takes for the database to be ready for use. For this reason, a system is designed to perform the automatic tuning of the database using the Nesterov accelerated gradient algorithm to change the value of the parameters that can improve database performance. The system is implemented in MariaDB database as the main database. Tests are carried out to change the previously set parameter values and the optimal parameter values are obtained after the 7th iteration. When testing the performance of the database with a large load, the database is able to significantly reduce the query time between before and after tuning. In the query load data of 1,000,000 database rows, there is a difference in the average execution time between before and after tuning with the Nesterov accelerated gradient algorithm of 1 minute 35 seconds. Whereas in the query load data 1,500,000 Row the average decrease in execution time is 14 minutes 26 seconds. From the test, it can also be concluded that the execution time is stable after the tuning process is carried out with the Nesterov Accelerated Gradient with the required execution time ranging from 24-45 seconds on testing load data of 1,000,000 rows and 75-120 seconds on testing load data of 1,500,000 rows.

Abstract

Vehicular Ad-Hoc Network (VANET) is a technology developed to provide communication services among vehicles. VANET aimed at improving road safety, necessary warning systems and so on. Before being able to communicate a very important process that must be done is the routing process. Routing process is a process to determine the path that will be passed by the information to be sent properly, efficiently, and precisely. The method to run this routing process is routing protocol. Based on several problems encountered in the urban environment, one of which is the clustering of vehicles caused by traffic light,a study is needed that examines the impact of movement flows and grouping of vehicles influenced by the presence of traffic light on the performance of routing protocol. Then a solution is needed, namely the implementation of a routing protocol that uses vehicle geographic information for the routing process, namely Greedy Perimeter Stateless Routing (GPSR) routing protocol. By using end-to-end delay, Packet Delivery Ratio, Overhead Routing, Normalized Routing Load and Convergence Time as test parameters. Based on the results from test parameters, scenario without traffic light has better results even though in Convergence time is still better if there is traffic light.

Abstract

Fault tolerance is the ability of the system to be able to continue running even when it is damaged. Fault tolerance has several types that are often used, in this study will be discussed about TMR (Triple Modular Redundancy). TMR is a hardware redundancy technique that duplicates 3 computing modules, and there will also be a voter polling the computational module. The voter's job is to see if any of the computing modules are damaged. However, in this study, the TMR voter will also be triplicated to reduce the possibility of a single point of failure, namely the event that the system cannot function if one of the modules is damaged, in this case is the voter. The device used as a computing module in this study is Arduino Uno, this study also uses the FC-37 rain sensor as an experimental sensor to retrieve the data. The result of this research is that the reliability value of the Triple Modular Redundancy system with Triplicated Voting is 98.49%, which is an increase compared to Triple Modular Redundancy with only 1 voter, which is 92.74%. The success rate of experiments conducted on Triple Modular Redundancy with Triplicated Voting also generally increased.
