Abstract

Robotics technology has progressed rapidly since its debut in 1922, evolving from simple programmable automation to highly sophisticated systems. This study employs a hybrid methodology, combining qualitative analysis of key robotic components manipulators, controllers, end effectors, and geometric configurations with quantitative comparison of performance metrics to classify robots according to their technological level (low-tech versus high tech). The findings show clear distinctions across these levels. Low-tech robots typically achieve positioning accuracy of about 0.025 mm and rely mainly on single electric motor actuation, making them suitable for simple, repetitive tasks. In contrast, high-tech robots can perform complex operations with positioning accuracy of up to 3 mm, integrating multiple actuation systems such as electric, pneumatic, and hydraulic mechanisms for enhanced flexibility and control. Moreover, high-tech robots exhibit greater manipulative capabilities and advanced control systems that enable multi axis and adaptive operations not feasible for low-tech counterparts. These results demonstrate how the technological level directly shapes a robot’s precision, actuation complexity, and functional range, providing a clear framework for selecting appropriate robotic solutions in both industrial and research settings.

Abstract

E-commerce telah berkembang pesat, dengan visualisasi produk dan kecerdasan buatan (AI) menjadi faktor kunci dalam meningkatkan pengalaman pengguna dan membantu pengambilan keputusan pembelian. Penelitian ini bertujuan merancang dan mengembangkan aplikasi web Virtual Try-On untuk produk busana, di mana pengguna dapat melihat pakaian dalam bentuk model 3D interaktif serta memanfaatkan fitur chatbot AI untuk rekomendasi fashion. Aplikasi dibangun menggunakan framework React.js di sisi frontend dan Three.js untuk merender model 3D pakaian yang dapat diunggah (upload) ke sistem. Fitur 3D memungkinkan pengguna memutar, memperbesar, dan melihat pakaian dari berbagai sudut seolah-olah mencobanya secara virtual, memberikan gambaran yang lebih nyata dibanding foto 2D. Selain itu, diintegrasikan AI “Gemini” sebagai virtual stylist – berupa chatbot interaktif yang dapat menjawab pertanyaan seputar produk dan memberikan saran outfit personal. Metodologi penelitian meliputi analisis kebutuhan, perancangan UI/UX, implementasi sistem, serta pengujian fungsional (black-box) dan uji coba pengguna. Hasil implementasi menunjukkan platform e- commerce dengan fitur try-on 3D dan chatbot AI dapat berjalan dengan baik. Pengguna dapat berinteraksi dengan model 3D secara lancar dan mendapatkan rekomendasi fashion secara real-time. Fitur-fitur ini terbukti meningkatkan pemahaman pengguna teqrhadap produk sekaligus memberikan dukungan keputusan yang lebih akurat melalui teknologi AI. Pengujian menunjukkan seluruh fungsionalitas utama sudah sesuai kebutuhan, dan umpan balik pengguna awal mengindikasikan pengalaman belanja yang lebih interaktif, informatif, dan percaya diri dengan adanya visualisasi 3D dan asisten virtual.

Abstract

Public attention toward the Free Nutritious Meal Program (Program Makan Bergizi Gratis/MBG) has increased following mass food poisoning incidents in various regions. Data from the National Nutrition Agency (Badan Gizi Nasional/ BGN) up to September 2025 recorded 6,517 affected students, while the Indonesian Education Monitoring Network (Jaringan Pemantau Pendidikan Indonesia/JPPI) reported 11,566 victims as of October 12, 2025. This situation triggered widespread discussion on social media, with YouTube serving as the main platform for public opinion. The large number of unstructured comments rendered manual analysis ineffective, necessitating the use of automated analytical methods. This study aimed to analyze public sentiment toward the MBG program and compare the performances of the Support Vector Machine (SVM) and Random Forest algorithms. This study adopts a quantitative approach using 7,522 YouTube comments as the initial dataset, which are processed through data collection, text preprocessing, data labeling, and TF-IDF feature extraction stages. Subsequently, the SVM and Random Forest models were trained and tested to classify sentiments into positive, negative, and neutral categories. The model performance was evaluated using Accuracy, Precision, Recall, and F1-Score metrics. After the preprocessing stage, the number of data points used in the sentiment analysis decreased compared to the initial dataset. This reduction resulted from data filtering, in which irrelevant, duplicate, or sentiment-unclear data were removed from the dataset. The final cleaned dataset consisted of 7,030 YouTube comments regarding the Free Nutritious Meal Program (MBG). The results show that public opinion is dominated by neutral sentiment (77.17% or 5,425 data points), followed by negative sentiment (15.21% or 1,069 data points), which proportionally exceeds positive sentiment (7.62% or 536 data points). In the modeling stage, the Support Vector Machine (SVM) algorithm proved to be more robust and effective in handling imbalanced data than Random Forest. However, the Random Forest achieved a slightly higher accuracy (83.42% compared to 82.71%).
