Abstract

One phase in database design for developing a software is a database design, this phase created based on conceptual and relational models. The process that is quite difficult is when mapping databases. When user requirement changed, it will have an impact on the design of the Database System that has been made before. In addition, a complex database structure, when experiencing changes will take a lot of time to be manually mapped. Based on these problems, A system was created to map the database model in the form of ERD so that it can be directly used on MySQL databases. With the goal to ease the mapping process, this system uses Chen's notation. This notation is the most used notation in the data modeling tool because it is easily read and interpreted. But this notation is rarely used by the ERD mapping application. This system uses seven steps of Entity Relationship diagram mapping so that it complies with the rules of Software Engineering. The system is made by web-based, using object-oriented programming, and using the Codeigniter framework. The system develop 16 requirement that has been tested using white-box and black-box testing in order to get best result in Chen's notation ER diagram mapping and the final testing results as expected, and compatibility testing got 95% valid result.

Abstract

6LoWPAN is a network technology that is proven for IoT environment to facilitate the transmission of data from sensor node to IoT middleware. The advantages of 6LoWPAN are it is suitable for low-power device and has high scalability because it is based on IPv6. But, there is a challenge in forming communication between node sensor and the IoT middleware in 6LoWPAN, i.e. node sensor can't find out the existence and the middleware address. Beside that, node sensor also can't self-configured it's IP address using the prefix that is provided by the middleware. These problems can be resolved with Neighbor Discovery Protocol (NDP), which can give node sensor the ability to automatically find out the middleware existence and address also can self-configured it's IP address. NDP can be applied with radvd program on the middleware side and ndisc6 program on the node sensor side. The result of this research are node sensor can find out the existence and the middleware address, automatic IP addressing in node sensor, discovery delay around 1ms , the number of exchanged NDP control message of each node is six, packet delivery ratio of CoAP and MQTT are 93% and 100%, and the maximum reachability range is 105m.

Abstract

Mobile Ad-Hoc Network (MANET) is a network technology that is composed of a collection of similar or different ad-hoc nodes that are connected using a wireless connection. MANET development is very likely to be applied to areas or conditions with minimal network infrastructure, such as disaster areas. Qualitative data analysis was performed on Dynamic MANET On-Demand (DYMO) and Cluster Based Routing Protocol (CBRP) performance by saving data from test results consisting of convergence, average throughput, average delay, average jitter, and package loss. From the results of the test analysis, the DYMO protocol has better results than the CBRP protocol based on the scheme of variations in the number of nodes. The average value of parameter throughput, average end to end delay, average jitter, and packet loss are 102.09 Kbps, 73.54 ms, 11.81 ms, and 1.79% respectively. In the wide variation scenario, DYMO is better seen from the average end to end delay, average jitter, and packet loss parameters with a value of 18.98 ms, 3.07 ms, and 0.35%. While the CBRP protocol is better of the average throughput with a value of 105.74 Kbps. In the data packet size variation scheme, the DYMO protocol is also known to be better seen from the average end to end delay, average jitter, and packet loss parameters with values of 32.86 ms, 8.44 ms, and 0.53%. While the CBRP protocol is better of the average throughput with a value of 104.86 Kbps. A better convergence value is obtained from the CBRP protocol with an average convergence time of 0.755375 seconds, but from the routing routing protocol level, the DYMO protocol is better than CBRP.

Abstract

Citrus plants are one of the important plants that get a special consideration by the Indonesian government. Based on research conducted by the Indonesian Ministry of Agriculture, citrus plants have rapid experienced development every year both in terms of the area of agricultural, the amount of production, and the increasing number of market demands. Even though the production of citrus plants continues to increase, in reality the citrus farmers have many obstacles in the field, one of which is the knowledge of diseases that exist in citrus plants, thereby reducing the productivity of the citrus fruit itself. Vize AI is a web service that provides an API for image recognition that can be trained to recognize and classify any kinds of images including a custom image. The author takes advantage of the opportunity to develop mobile-based applications with Android OS that can identify diseases from image of citrus leaves into 3 diseases, namely Downy Mildew, Cendawan Jelaga, and Citrus Vein Phloem Degeneration (CVPD) by using Vize AI. Applications that have been made by the author have some features that meet the user's need and implemented in Java programming language. After accuracy test is done, the results of the accuracy of this application in detecting citrus leaf's disease is highly accurate result with a percentage of 100% and accuracy of calculation of severity has an average accuracy of 65%. But these results still depend on the type of image quality itself.

Abstract

Alquran is Muslims holy book which have to be read by paying attention to its letters pronunciation. Because even a little mistake in pronunciation resulting in damage to the meaning of Alquran itself. The process of learning to read the Koran requires a guide to correct mistakes that might occur. However, due the limited of time, then there is also limited opportunity for someone to practice reading Koran with a guide. One solution that the author offers is through the media based on Android application to detect errors in reading the verses of Koran. In the development of the application, the Waterfall method was used which began with interviews with a mosque imam and 2 students. Then the application is designed with the Object Oriented Design method and implemented with the Object Oriented Programming method. The result of its implementation is that the application utilizes Speech Recognizer to translate user readings into Arabic text. While Levenstein Distance algoritm and Diff Match Patch Library handle the error detections in user's pronunciation. At the accuracy testing stage it was found that this application successfully completed 3 of the 4 test cases performed. While at the usability testing stage with the System Usability Scale method this application gets a score of 76 with a level of satisfaction B + or above average. The application must be further developed because the level of accuracy obtained is still too low.
