Abstract

Traveling is one of the needs of everyone to relax the mind from the busyness that is lived every day. One of the cities in East Java which is a prima donna for traveling is Malang. The city has approximately 43 tourist destinations. Usually, tourists who want to visit not only one place, but several places. generate assistance in deciding which destinations to visit first in order for their trip to be effective. The shortest search process in this study uses the A-Star Algorithm, one of the BFS algorithms which in the process really considers the heuristic value. The process of testing the shortest route is done by selecting a starting point, then selecting several tourist locations. Next, the shortest route will be searched using the A-star algorithm at each destination, then which destination will be visited first. And so on until the final destination. The effectiveness of the route which involves comparison with the route presented by google maps. Based on the results of 30 experiments on several comprehensive destinations, it was found that the average route search using the A-Star algorithm was 44.17% shorter than that presented on google maps. This is due to the uniqueness of the algorithm in which there is a heuristic value and selection for each destination so as to make the route more effective.

Abstract

Lightning is an inescapable natural occurrence in the Earth’s atmosphere. Lightning is extremely harmful since the energy released can reach up to three million volts. Lightning strikes are difficult to forecast in terms of time, position, and intensity, therefore they may result in physical losses as they often result in fatalities. One method that can be used to identify an area and time that is prone to lightning is the clustering technique. The clustering approach utilized in this study is the ST-DBSCAN algorithm (Spatio Temporal-Density Based Spatial Clustering Application with Noise), which groups data based on spatial and temporal aspects. The dataset used in this study is lightning spots in Malang City from 1 January to 31 December 2022, with a total of 16,800 data. The most accurate analysis findings revealed four clusters and 26 contained noise, giving a Silhouette Coefficient value of 0.104 which employs parameters such as spatial distance (Eps1 = 0.2), temporal distance (Eps2 = 7), and minimum parts of spots within the group (MinPts = 7). Lightning strikes in Malang City in 2022 are anticipated to be frequently encountered between January and July in the first cluster, totaling 13.337 spots and the least occurred in August with 110 spots.

Abstract

Hypertension is one of the leading causes of death worldwide. This disease is often referred to as the silent killer because it can lead to death without noticeable symptoms, leaving those affected unaware of their condition. Therefore, early detection and management of hypertension are crucial. This research aims to obtain the classification of hypertension using the Support Vector Machine (SVM) method by utilizing various attributes such as age, smoking habits, lifestyle, blood pressure, and hypertension diagnosis, as well as determining the accuracy level of hypertension classification results using the SVM method. The SVM method is trained with various kernel parameters and hyperparameters to find the best model. The research findings indicate that the best model for classifying hypertension using the SVM method employs the RBF kernel with parameters = 100 and  (gamma) = 0,1, achieving an accuracy of 97.15%. This demonstrates that the SVM method is capable of classifying hypertension very well and significantly contributes to the early detection and management of hypertension.

Abstract

Forest fires are a serious problem that almost always occur in Indonesia every dry season. In 2019 and 2023, many forest fires occurred, especially in Gambus land, due to the prolonged El-Nino phenomenon. This has a negative impact on the economy, social and environment. Therefore, clustering is an important effort to find out the location of areas where forest fires occur. Clustering is a technique used in data mining which works by searching and grouping data that has the same characteristics between one data and other data obtained. This research aims to determine the results of clustering of hotspot distribution patterns in forest fires in Indonesia using the ST-DBSCAN method. The ST-DBSCAN method is a clustering method used to group data using spatial and temporal parameters. The results of this research produced five clusters, noise of 31, and silhouette coefficient of 0.401 with optimal parameters, there are Eps1 = 0.3, Eps2 = 7, and MinPts = 14.

Abstract

Speech recognition is a process of voice identification using specific parameters taken by the sound catcher. The development of technology gave rise to an event that requires a calculation model on a computer system in speech recognition to be useful in science. One of the computer systems is the Backpropagation Artificial Neural Network (JST). This research uses the Backpropagation method in human speech recognition with the aim of knowing the architecture model and the level of accuracy obtained. Linear Predictive Coding (LPC) is used for voice feature extraction. Voice features in the time domain are converted into the frequency domain using Fast Fourier Transform (FFT). The voice data was divided into 80% training data and 20% testing data. A suitable JST architecture model is selected through training by calculating the optimal weights and biases to recognize the voice patterns well. The best architecture model found was 64-15-1-1. The model was tested using test data to test its ability to recognize voice patterns. Evaluation was done using K-Fold Cross Validation to measure the accuracy of the model. The accuracy value against the training data is 0.95, while against the testing data is 0.088886. The JST architecture model is very good at recognizing voices in training data, but less good in testing. Hopefully, this method can help in the research process related to recognition.

Abstract

PT Citra Akes Indonusa is a company that operates on the expertise of information technology services in Banten Province. One of the services provided by the company requires the construction of a Base Transceiver Station (BTS) tower. The tower requires maintenance if there is damage to the network signal. As a result, the shortest route is needed to make it easier for employees to reach the tower location to be more effective. There are eight BTS tower locations in Tangerang Regency and three BTS tower locations in Tangerang City. The process of finding the shortest route in this study uses the Floyd Warshall algorithm, which is unique in finding the shortest route by comparing each edge of all edges that are passed. The process of testing the shortest route is done by selecting the starting point, then selecting several BTS tower locations. Next, the shortest route will be searched using the Floyd Warshall algorithm from each point of destination for the BTS tower location, then the BTS tower location will be selected first and so on until the last destination. The effectiveness of this shortest route search involves a comparison of the routes presented by Google Maps. Based on the results of 30 randomized trials on BTS tower locations, the average shortest route effectiveness was 25.54% compared to the route generated by Google Maps. This is due to the selection at each BTS tower destination location so as to make the route more effective.
