Abstract

Internet of Things (IoT) can be interpreted as a concept to connect "Things" or real objects in the world with the internet and sharing information. To share information between "Things" over the internet, Iot needs an ideal and efficient communication protocol in terms of resources when sending messages. One of the protocols considered to fit with IoT communication model is the Message Queuing Telemetry Transport (MQTT) protocol. In the MQTT protocol communication model, the broker has an important role in the success of the communication process that occurs. When the broker stops, the publisher and subscriber can't make the communication process and have to wait for the broker to be fixed. The solution of broker problem can be minimized by implementing failover between master and slave broker. Therefore, this study implements failover to improve the availability of services to brokers. Based on the test results, the system obtained an average downtime value of 24.3266 seconds from 5 tests. While on performance testing, the system gets an average latency value of 1.1763 seconds on the publisher side and 0.1157 seconds on the MQTT subscriber side. In packet loss testing, missing messages amount to 20 messages from 50 messages when implementing failoverl.

Abstract

Nutrition is a compound which important to human growth and their health. Nutrition consumption is really important that they can affect health if poorly managed. Unfortunately, there are still places which have poorly managed nutrition planning, which one of them is Orphanage. Improved Particle Swarm Optimization is an Evolutionary Algorithm which is based on nature folks of birds flying in group searching for new food points. This Algorithm have great ability to search local optimum solution and also global optimum solution. In this case, a list of foods menu will be represented by a Particles which consisting indexes of number represent menu. The result of our testing found that swarm size of 70 and combination of 2,0 for C1 and C2 is the best parameter for this problem. Although giving great solution based on Nutrition, this algorithm still offer total price above our limit value.

Abstract

The data transmission process in the technology sector is increasingly being applied wirelessly. A wireless data transmission architecture that is often implemented is called the Wireless Sensor Network (WSN). In solving certain problems, wireless data transmission is carried out continuously so that it requires large amounts of electricity. In addition, the mechanism for making alternative data transmission lines is needed when data transmission through the main line is experiencing problems. This mechanism is needed so that data transmission is not interrupted even though the main transmission line cannot be used. But solutions using these mechanisms have the consequence of increasing the required electrical power. Another solution offered in this study is to enable sleep mode with a low power node design so that power consumption is focused on the data transmission path that is being used. The design of this solution utilizes nRF24L01-based Atmega328P microcontroller which activates one of the transmission lines that are to be used and deactivates (sleep mode) on the transmission line that is not being used. According to the results of experiments that have been carried out, the average value of the electric current when applying sleep mode is 60.45182 mA and electrical power is 5.44 watts. This value is smaller than a system without sleep mode that requires 73.38182 electric current and 6.6 watts of electric power. This proves that the proposed method was successful in reducing electricity consumption.

Abstract

At Universitas Kanjuruhan Malang, the process of lecturer performance evaluation is related to the process of applying for promotion and lecturer certification. The current lecturer performance evaluation process uses an online assessment system, but has not been able to help lecturers more anticipate and measure the success rate in the process of applying for promotion and lecturer certification. In the old system the evaluation results file were still separated, making it difficult for the lecturer to use it for submission of promotions. Based on these problems, this research develops a lecturer performance evaluation system that accommodates the evaluation of lecturers evaluation results in the form of lecturer credits and can help lecturers to conduct simulations of evaluating the success of lecturer certification submissions and help lecturers to anticipate lecturers to submit lecturer promotions. In this research the requirement analysis process produced 37 functional requirement and 1 non-functional requirement involving 4 Actors, the design and implementation process produced architectural, components and interfaces designs with the results of code implementation, data implementation resulted in 8 data tables, and interface implementation. Implementation results were then tested with Whitebox testing using unit tests with 4 samples 100% valid and Blackbox testing using validation testing with 37 test cases 100% valid.

Abstract

Virtual Reality (VR) is a term in a 3D environment generated by a computer and has the ability to make users to be able to interact with alternative realities. To interact with virtual reality, users need devices that accommodate user interaction with the VR environment. A room scale VR device is capable of allowing users to interact more freely. VR devices that currently available in the market still require supporting external devices, resulting in a lack of device portability. Based on these problems, researchers developed a device based on head orientation and head position on a room scale. In the development of devices, testing is done to determine the performance of the device system. Testing of device systems involves the application of Mahony Filters as orientation filters. Tests are based on orientation data and position of user's head in a room. The testing of the device system obtains detection accuracy of head position data acquisition in a room area of ​​3.33m2 with an average deviation of 4.9cm from the range of actual space size and for the accuracy detection of orientation data by system, the average degree deviation is 2.59 degrees from the actual degree angle. In the classification of determining the heading by the system, that obtained success rate by 73.5%.

Abstract

House is a place to live in which isthe construction really needs special attention to make it a dream home. Building a house is not an easy matter for people in general, because building a house requires a lot of costs and needs to be considered. Likewise, the time needed to consider in building a house so that overtime does not occur which also results in over budget. The first problem that occurs is overbudget, namely the existence of an unexpected and excessive reporting expected by the person who is going to build a house and usually that person has previously done a budget calculation manually so that it can produce the results of the calculation manually and the funds actually processing the development process. The second problem that occurs is overtime, namely the existence of construction work time that is past the predetermined time. These problems are also interrelated because the craftsman cannot finish his work according to the desired target will result in overbudget. Likewise, a compilation of people need problems finding the location of the nearest building material store, this takes quite a long time just to find the material. This can also cause overtime because the builders can use 100m2 in a day because searching for the final material can only finish 75m2. To consider this problem the development of a system that aims to make it easier for someone to calculate the cost of building an Android-based home. The results from unit testing, integration testing, validation testing and accuray testing produce 100% valid.

Abstract

Artificial Intelligence in video games is made to offer a challenge for the players. However, most of the AI only use simple rules to decide where to move. Those simple rules are the distance between the other opponent's unit, attack range, unit's power, etc. This kind of behavior is usually predictable and tend to be exploited easily. Genetic algorithm is an algorithm that provides various solutions to a certain problem. Thus, in this research, we use a genetic algorithm to control the unit movements. The algorithm will evaluate various factors before it is going to decide on where to move. These factors are the potential damage, potential loss, the distance of each unit to the midpoint, and the distance to the enemy main headquarter. Based on the research result, we can conclude that using a genetic algorithm as an artificial intelligent agent prove that the movement pattern of the units are less predictable. Additionally, they will still try to satisfy the goal given to them.
