Abstract

Machine learning methods are used to detect elderly accidents while image processing is used to support machine learning performance so that detection performance can be better. This study used two methods used simultaneously, namely GLCM and ANN. The study consisted of preparation of human gesture datasets, preprocessing stage, application of GLCM, analysis of feature extraction results, classification using ANN and analysis of motion class detection results. Overall, the GLCM method with homogeneity parameters and ANN as a classifier obtained an accuracy of 24.32%. The GLCM method with contrast parameters and ANN as a classifier gets an accuracy of 99.84%. The GLCM method with mean parameters and ANN as the classifier gets an accuracy of 99.99%. The GLCM method with dissimilarity parameters and ANN as a classifier to classify hand movement images gets the best accuracy of 100%.

Abstract

By leveraging spatial data, new approaches to vessel traffic safety risk assessment can be developed, enabling a better understanding of vessel trajectories and improving overall maritime safety in congested and hazardous aquatic environments. This study aims to design an application for monitoring ship movement traffic in marine waters by applying the Haversine Formula algorithm. This method is used for calculating the distance between the nearest ports from the position of the ship, this aims to facilitate decision making in case of emergencies. From the experimental results, the comparison of values with Google Maps gets an average of 10.3 with the smallest difference of 2 and the largest 34, this still indicates that the calculation of the estimated distance of the ship to the nearest port using the haversine formula in the ship traffic monitoring dashboard system has slightly better accuracy than using the Google Maps application. The design of the system prototype has been successfully carried out based on the design of use case diagrams, activity diagrams, and class diagrams as well as the design of the interface display, has modules including; traffic module, ship module, voyage module, history module, port module.

Abstract

Software product development not only focuses on features but also usability aspects. User experience is very important in the evaluation of reusability to understand the user's interaction with the product or system. Reusability factors include user satisfaction, efficiency, and effectiveness to achieve specific goals. The main purpose of this study is to evaluate the usability aspect of online ticket booking applications. This evaluation process is important to identify development and improvements to user views and application usage satisfaction. In this study, the object studied was an online travel booking application in Indonesia. The research instrument uses a quantitative and qualitative mixed-method approach. For the quantitative approach, the System Usability Scale (SUS) is used and as a basis for a qualitative approach, the D&M IS Success Model approach is used. Based on the evaluation results, there are several points that should be improved including the interface design should be simple, the reduction in the size of memory used by applications, features to communicate with customer service easily, data integration, and time notifications to complete payments.

Abstract

Di era teknologi saat ini, salah satu media sosial yang banyak digunakan dalam berinteraksi dan memberikan opini, pengaduan masyarakat, serta saran adalah Twitter. Dalam bidang pemerintahan, tweet yang mengandung opini atau pengaduan masyarakat terhadap suatu layanan atau program organisasi dapat digunakan sebagai umpan balik untuk memperbaiki atau meningkatkan kualitas layanan. Penelitian ini berfokus pada klasifikasi tweet untuk membedakan tweet yang tergolong pengaduan masyarakat atau non-pengaduan masyarakat dengan menerapkan algoritma pemelajaran mesin yaitu logistic regression (LR). Tahap dari penelitian ini antara lain crawling dan labeling dataset, pre-processing, pemodelan menggunakan classifier logistic regression, serta evaluasi kinerja classifier. Tahapan dalam penelitian ini seperti preprocessing, klasifikasi dan evaluasi dilakukan menggunakan bahasa pemrograman Python dengan bantuan scikit-learn library. Berdasarkan hasil eksperimen, model penelitian dengan menggunakan fitur ekstraksi CountVectorizer mencapai kinerja yang lebih baik daripada TfidfVectorizer. Eksperimen dengan menggunakan ekstraksi fitur TfidfVectorizer mencapai akurasi 92% (F1 score: 0.9181, precision: 0.9191 recall: 0.9181, kappa: 0.8363) sedangkan menggunakan akurasi CountVectorizer mencapai 94% (F1 score: 0.9355, precision: 0.9406, recall: 0.9356, kappa: 0.8715).

Abstract

Teknologi informasi dapat menjadi media pemanfaatan tanaman etnofitomedisin dan membantu menyebarkan kembali pengetahuan masyarakat tentang etnofitomedisin untuk meningkatkan kekebalan tubuh dan mencegah penyakit. Melalui pengembangan aplikasi manajemen data, hal ini akan membantu dalam melestarikan pengetahuan etnofitomedisin, mengidentifikasi spesies tanaman etnofitomedisin dengan sifat obat, mendokumentasikan penggunaan tamanan etnofitomedisin, dan memahami lokasi sebaran tanaman. Dalam penelitian ini, aplikasi dibangun dengan menggunakan pendekatan Web Information System Development Methodology (WISDM). Aplikasi ini memungkinkan administrator dapat mengelola seluruh data sedangkan contributor hanya memiliki akses untuk mengelola data plant utilization, data knowledge source dan data literatur. Aktor pengunjung hanya dapat melakukan pencarian konten dan melihat konten. Selanjutnya dibahas mengenai hasil tahapan human-computer interface untuk model aplikasi etnofitomedika. Ada enam perancangan human-computer interface yang utama pada model aplikasi antara lain halaman antarmuka beranda, halaman antarmuka hasil pencarian, halaman antarmuka detail berdasarkan tanaman, halaman antarmuka detail berdasarkan penyakit, halaman antarmuka detail berdasarkan etnis dan halaman back-end

Abstract

In digital business, companies must be able to survive to attract the attention of consumers. One way is to think about how to increase the factors supporting buying interest such as application quality, brand image, price, trust, value, and so forth in order to application can be used by the public continuously. This study aims to determine how the influence of brand image, price, trust and value of consumer perceptions of increased purchase intention for online transportation service provider applications. This research is quantitative research by processing data using SmartPLS. Data collection was carried out by using a questionnaire method which is distributed to users of transportation service providers for two months with a total of 983 collected data. The results showed that the value has the greatest influence on purchase intention with a t-value of 11.619. Furthermore, trust also has an influence on purchase intention with a t-value of 5.628. Brand image also has the influence of purchase intention with a score of 5.253. Price lacks the influence of purchase intention (purchase intention) with a score of 0.749. Customers do not think about prices because there are no significant differences between other online transportation service providers and tend to be cheaper than offline transportation services.
