VANET network is one network that can be used to communicate between one vehicle and another vehicle. With the existence of the VANET network, it is expected to be able to improve the safety of drivers on the highway. One of the uses of the AOMDV routing protocol is that it can be used to help the performance of the VANET network, the AOMDV routing protocol. AOMDV routing protocol in conducting route search there are two working mechanisms namely route discovery and route maintenance. The route selection process in the AOMDV routing protocol is to consider the number of hops contained in the AOMDV routing protocol, so that the possibility of a broken link, therefore the need for the application of the method in conducting this research. The ant algorithm is one method that can optimize the process of finding a route in the AOMDV routing protocol. The ant algorithm in carrying out the route search is by calculating the distance between nodes. In the ant algorithm, the route selection is based on the most powerful pheromones, so the route chosen is no longer based on the number of hops. From the results of trials that have been carried out on the AOMDV routing protocol using the ant algorithm can improve the performance of the test throughput parameters of 9.7649 Kbps and the performance of the Packet Delivery Ratio of 11.2838%. Whereas the average end to end delay parameter can reduce the delay by 13.3093ms</em></p> Ni Desak Ketut Pujika Dewi Andy Hidayat Jatmika Ariyan Zubaidi ##submission.copyrightStatement## 2020-09-29 2020-09-29 2 2 162 172 10.29303/jtika.v2i2.97 Klasifikasi Kain Songket Lombok Berdasarkan Fitur GLCM dan Moment Invariant Dengan Teknik Pengklasifikasian Linear Discriminant Analysis (LDA) http://jtika.if.unram.ac.id/index.php/JTIKA/article/view/98 <p><em>Songket is one of Indonesia's cultural heritage that is still present today. One of the most famous songket woven fabrics is the Lombok songket. Lombok songket has diverse, unique, and beautiful motifs. However public knowledge of Lombok songket motifs is still minimal and the difference between one motif with another is still unknown. The lack of digitalized data collection is one reason for this. Therefore, we need a system that can classify the Lombok songket automatically. In this study, a system was developed based on texture features and shape features using Linear Discriminant Analysis (LDA). The GLCM method is used in the texture feature extraction process and the Invariant Moment method is used in the feature extraction process. The total data used in this study is 1000 images from 10 Lombok songket motifs which are divided into training data and test data. The highest accuracy is obtained on the Invariant Moment and GLCM feature with an image resolution of 300x300 pixels using the most effective feature that is equal to 96.67%.</em></p> Nurhalimah Nurhalimah I Gede Pasek Suta Wijaya Fitri Bimantoro ##submission.copyrightStatement## 2020-09-29 2020-09-29 2 2 173 183 10.29303/jtika.v2i2.98 Implementasi Fuzzy Tsukamoto dan IoT Pada Sistem Pendukung Keputusan Tingkat Kepadatan Lahan Parkir http://jtika.if.unram.ac.id/index.php/JTIKA/article/view/100 <p><em>Parking lots are a common thing in everyday life. The problem of parking lot's density can be a problem for managers of a place. So to overcome the problem that can occur, this study aims to design a decision support system (DSS) to determine the density of parking lots by applying the concept of IoT and Tsukamoto's fuzzy method. IoT is used to automate data retrieval to create fuzzy rule patterns. In the Tsukamoto method, each rule is represented by IF-THEN. The method for system design in this study includes the design of hardware and software. In this design, data retrieval uses an ultrasonic sensor HC-SR04 and is processed with the IoT concept using Arduino UNO and ESP8266 microcontrollers. The sensor is placed on the exit and entry path of the vehicle on the parking lot to detect vehicles entering and exiting. The parking lot used in this study is miniature. Vehicle data is processed using Tsukamoto's fuzzy logic to determine parking density decisions. Data variables used are time, duration, and density of parking lots. DSS is designed using the Laravel framework. Based on the test results, it is known that IoT devices can perform their functions properly. DSS that is made in the form of a website can also function well. The results are based on error testing, obtained error for determining the parking density level is 7,68%.</em></p> Indraning Tyas Adhitria I Gde Putu Wirarama Wedashwara Wirawan Ahmad Zafrullah Mardiansyah ##submission.copyrightStatement## 2020-09-29 2020-09-29 2 2 184 195 10.29303/jtika.v2i2.100 Implementasi Metode Simple Additive Weighting (SAW) dalam Sistem Pendukung Keputusan Penentuan Penerima Bantuan Korban Bencana Alam Gempa (Studi Kasus : BPBD Lombok Barat) http://jtika.if.unram.ac.id/index.php/JTIKA/article/view/101 <p>Bencana alam gempa merupakan salah satu bencana alam yang mengakibatkan kerugian materi maupun non materi bagi daerah dan masyarakat yang terdampak.
