Abstract

Advancement in technology helps the development of hobbies such as listening to music and playing games, but in reality, both hobbies done simultaneously is rarely met, because of that, a program was developed to help in combining both hobbies into one activity with the help of Unity game engine while using widely known OGG audio file format to generate a level for a platforming game.Genetic algorithm was used as a method to deliver a process of developing level with hopes that the level structure matches the difficulty chosen by user, while also reducing the probability of a same level appearing twice, increasing game repetitiveness and minimalizing bore level.Penggunaan Audio Spectrum dan Genetic Algorithm Untuk Obstacle Generation Game Platforming Berbasis Musik

Abstract

Teaching and learning process are growing over time and technology behind it are growing too so that the process of learning with online media or often referred to as e-learning where provided media that can be accessed via the internet. This phenomenon is interesting to examine because some e-learning systems that exist today are not yet fully secure, in the sense that it is still easy to be disseminated without any copyright and not used wisely. The purpose of this research is to produce an application that can be used as a media for e-learning of streaming audio and video without storing the file on local cache device so that the file residing in e-learning media cannot be disseminated and be used wisely. As a research methodology using deductive qualitative method, data collective process is done by literature study, interview, and observation. After the data collected, will result e-learning software based on website and mobile that can be used to stream media files without downloading it. The result of this test and analyze shown that streaming with RTSP protocol is can be used into e-learning software with a limited users.

Abstract

In modern times, humans have been helped by many technological developments. One such field is the goods delivery field, called the Vehicle Routing Problem (VRP). Vehicle Routing Problem is a matter of where there is a freight fleet that has to deliver a certain amount of goods to various customers. The solution sought is the shortest route the fleet can take.,Hybrid Ant Colony Optimization (HACO)is an algorithm that is inspired from the foraging behaviour of ant species, that is one of the result of  development for Ant Colony Optimization. HACO has been published by Q. Ding et. al in 2012 to solve Vehicle Routing Problem with Time Windows. However, in that published journal, there were vagueness in some points like process time and memory usage. Therefore in this journal there is a need to review the performance of HACO to solve VRPTW, which will be done using unity. In this thesis is also discussed some development of HACO which are expected to fix and improve the result of HACO.

Decision-making system is one way to achieve a certain goal to be achieved. Decision-making system can be done through the process of data collection, and with consideration of determining the decision. In determining this decision required a method to overcome the problem, namely by using the method of Simple Additive Weighting (SAW).Based on the results of bakers, 60% of respondents rated well in appraisal of apps, 40% of respondents rated very well in assessing the ease of use of the application, 50% of respondents rated good in assessing the completeness of information, 50% of respondents rated good in assessing conformity in needs, 40% respondents rate good in assessing the resulting report, 50% of respondents rate good in assessing the overall application.

Abstract

There are many disturbance that may occur during the learning process, both internal and external disturbances. Internal disturbance that may occur is the inactivity of a microphone or speakers in the classroom, the phone that accidentally sounds from students or lecturers also become an internal disturbance that may occur. On the other hand, external disturbances that may occur in the classroom are noise or out-of-class activities or there is a vehicle noise disturbing the tranquility. Another problem is when students are left behind in material explanations. Many students are also reluctant to re-ask the lesson that is left to the teacher who then even ask his own friends rather than the lecturers, thus disrupting the concentration of other students.To resolve the issue, an application that replicates the SmartHear application is created. This application can help lecturers and students to improve the quality of understanding during the learning process. The SmartHear app can also help students to record ongoing streaming sessions.Testing is done by trying various Android devices to deliver streaming and receive streaming results. Each android device with the API above 19 already meets the standards in order to run the application but there are other factors such as the size of random access memory (RAM) and the type of processor. This application is also created with a version that will process voice input with generalized maximum a posteriori spectral amplitude (GMAPA) algorithm, but this algorithm can not be processed properly in Android devices due to the lack of computing capabilities that can be done in android devices.

Abstract

Server room is room which is store server, networking hardware, etc. A server room must have standard security which is can protect devices like temperature of server room, humidity server room, fire, access to the entry of people who are considered less responsible.Lack of control and monitoring of room temperature and humidity are common. This is due to lack of supervision or control of the staff or admin of the server room. If the temperature and humidity of the server room is uncontrolled then hardware inside the room can be broke or the performance of the server devices can be decrease. Often the security of the server room from the reach of less responsible people is also under-scrutiny. So sometimes there are people who can enter into the server room without knowing the intent and its purpose.The solution to this problem is to use a room monitoring application, which can be used to control and monitor temperature and humidity in the server room, so that the temperature and humidity of the server room can be maintained. This app can also prevent unauthenticated people from entering the server room.
