Abstract

Tahapan pembangunan perangkat lunak atau lebih dikenal dengan istilah SDLC (Software Development Life Cycle) memiliki beberapa tahapan termasuk tahapan analisis. Dalam tahap analisis pemodelan ke dalam bentuk diagram biasanya dilakukan secara mendalam untuk memodelkan masalah yang dihadapi. UML merupakan bahasa de facto dalam pemodelan kebutuhan perangkat lunak berorientasi objek. Aplikasi pemodelan yang berkembang mayoritas lebih ditujukan untuk dunia industri serta memerlukan instalasi dan lisensi yang terbatas. Penelitian ini mengembangkan sebuah aplikasi pemodelan kebutuhan perangkat lunak khususnya pemodelan class diagram. Aplikasi dikembangkan berbasis web, sehingga tidak perlu ada instalasi dan tidak perlu membayar lisensi. Fitur yang dikembangkan yakni pengenalan notasi-notasi class diagram beserta  penjelasannya. Aplikasi juga menyediakan area kerja untuk menggambarkan diagram beserta fitur cetak hasil diagram yang telah dibuat. Aplikasi dikembangkan menggunakan metode pengembangan prototyping, sehingga didapatkan prototipe aplikasi. Prototipe aplikasi dapat terus dikembangkan sehingga mendapat hasil yang maksimal. Hasil pengujian fungsionalitas menggunakan metode pengujian black box didapatkan bahwa 100% fungsi berjalan dengan baik. Sedangkan pengujian user acceptance dengan tiga parameter didapatkan bahwa 92% responden setuju bahwa aplikasi memiliki kinerja yang baik, 90% responden setuju aplikasi mudah digunakan dan 89% responden puas terhadap aplikasi yang dibangun.

Abstract

Penelitian ini membahas masalah ketidakseimbangan data dalam klasifikasi risiko stroke, di mana kasus non-stroke secara signifikan lebih rendah daripada kasus stroke. Ketidakseimbangan kelas cenderung menimbulkan bias terhadap kelas mayoritas, yang menyebabkan berkurangnya efektivitas klasifikasi. Untuk mengatasi hal ini, SMOTE (Synthetic Minority Over-sampling Technique) digunakan untuk mengatasi ketidakseimbangan kelas dalam dataset dan algoritma K-Nearest Neighbor (KNN) digunakan untuk klasifikasi. Dataset mengalami preprocessing, aplikasi SMOTE, dan algoritma KNN dilatih dan dievaluasi menggunakan metrik standar termasuk akurasi, presisi, recall, dan F1-score. Penerapan SMOTE bersama dengan KNN menghasilkan peningkatan yang signifikan dalam hasil klasifikasi, mencapai akurasi 91,87%, presisi 94,27%, recall 89,20%, dan F1-score 91,66%. Temuan ini menegaskan bahwa pendekatan yang diimplementasikan berkinerja baik dalam mendeteksi risiko stroke meskipun ada set data yang tidak seimbang. Tujuan dari penelitian ini adalah untuk menginformasikan kemajuan teknologi deteksi dini stroke yang lebih kuat dan mendukung peningkatan dalam penyediaan layanan kesehatan.

Abstract

UPT Puskesmas Tirto is a public health center located in the West Pekalongan sub-district that provides maternal and child health poly services.  This poly provides educational services related to the problem of stunting in children through Posyandu activities. However, providing educational services is less effective and efficient because some parents do not have much time to attend counseling so information is not conveyed properly. This research aims to optimize the provision of educational services to parents, prospective mothers, and young women through the use of information technology by developing a website-based stunting prevention educational media service using the ReactJs framework. The development process of this research is carried out by prototyping method. Based on the results of testing using the Blackbox method, it shows that the main features such as nutrition check services, consultation services with Puskesmas nutritionists, and literacy services in the form of articles in the application can run well according to their functions in providing stunting prevention information with 100% results.

Abstract

Car rental has become one of the most profitable industries, as cars have become an essential means of transportation for various societal needs, such as family activities and work. Many car rental companies still rely on conventional methods for promotions and reservations. There is one car rental place whose rental and promotion system still uses WhatsApp chat and telephone or comes directly to the rental. A website-shaped system is crucial as a company platform to showcase available vehicles, enable online transactions for rentals, and facilitate easy and convenient payments. The development of this website involves prototyping with PHP and MySQL programming languages, and the payment system incorporates the Midtrans payment gateway. The system is tested using Blackbox and User Acceptance Testing (UAT). This website's development aims to simplify the booking process for customers and enhance the company's ability to manage vehicle data and payments efficiently. Following the system's construction, testing is conducted, with the results of the UAT indicating a user satisfaction score of 90.8%. Based on the evaluation, the majority of users strongly agree with the developed application.

Abstract

Digitalization drives business service optimization through more efficient and interactive systems. E-catalogs enable structured product information delivery but still have limitations in product search and customer interaction, which rely heavily on administrators. This study proposes the integration of a decision tree-based chatbot in a web-based e-catalog to enhance service efficiency and user experience. The prototyping method was implemented through four stages: requirement identification via interviews and observations, system design involving user interface and chatbot interaction flow, web-based implementation, and testing using Black-box Testing for functionality evaluation and the System Usability Scale (SUS) to measure user satisfaction. The results indicate that the system improves product search and ordering efficiency, with the chatbot providing automatic recommendations and reducing the workload of administrators. All system features functioned properly, and the SUS evaluation yielded an average score of 87.2. It is reflecting a high level of user satisfaction. The integration of chatbots in e-catalogs has proven to enhance service efficiency and customer interaction and can be applied to other SMEs facing challenges in digital promotion and order management.
