Abstract

One of the criteria in applying mobile navigation is the ability of mobile device to continuously monitor point of access from user, but in monitoring the point or the object always changes due to the movement of user. The changes occurring are known as split nodes. There is a method used to manage split nodes that is KNN search, but the performance is still not satisfactory. Another proposed method is the Voronoi Continuous K Nearest Neighbor (VCKNN) algorithm that uses the Voronoi diagram to help manage split nodes. The use of the VCKNN algorithm is supported by Dijkstra's algorithm in searching for split nodes within the Voronoi polygon. In this research will be done comparison between VCKNN and Dijkstra algorithm in managing split nodes. This is done to get algorithms that have the best performance in managing data on segmentation, runtime and split nodes. This research will take a study area of ​​Malang Raya. Selection of Malang Raya as a study area due to unstructured road network structure neat, so it can know the performance of the proposed algorithm. From this research, the results obtained using VCKNN algorithm occurs the performance improvement compared to Dijkstra's algorithm. Increased performance occurs due to the decrease in the number of split nodes produced. The decrease of split nodes that occur using the VCKNN algorithm based on the use of administrative boundaries sub-district as the interest point resulted in the decrease of split nodes by 92.4%. With the result of this research for Malang Raya road network condition, VCKNN algorithm yield satisfying result.

Abstract

The interest of Indonesians in having dog as pets is high. Dogs become favorite pets because dogs have funny and adorable habits. In addition, taking care of dogs is quite easy. Prevention and detection of diseases that infect dogs is necessary, so the infected dogs can be taken care of immediately to prevent transmission of the disease to other dogs and to human. Diagnosing the diseases could be a bit difficult sometimes because some diseases have similar symptoms. Another problem is that there are not many veterinary clinics that open for 24 hours so it would be difficult for dog owners if they found out that their dog was sick outside of the clinics' working hours. The system of dog diseases diagnosis is made to assist veterinarians in diagnosing dog diseases, in addition the system is expected to assist the community in making an initial diagnosis of their dogs. This system is Android-based and applies the method of Naive Bayes and Certainty Factor. The Naive Bayes method is used to classify dog diseases based on the usual pattern of symptoms, while the Certainty Factor method is used to determine the value of certainty of classification results from the Naive Bayes method. Based on the accuracy test that was done for five times, the average accuracy value obtained was 97.2%.
