Abstract

Lack of motivation and student involvement in the learning process is a challenge in education today. This problem can be solved by e-learning method which combines forms of learning with communication, technology, motivation, effectiveness and efficiency. E-learning, online and digital based learning media, allows students to study anywhere at any time. Basically e-learning is only used for storing teaching materials. This kind of e-learning cannot motivate the learning process, to increase learning motivation, e-learning development must be carried out. The proposed solution is to expand the Learning Management System (LMS) in web-based e-learning by developing and adding several additional features to improve the effectiveness and quality of learning. This web-based e-learning adds to the features of lecturers and students in terms of communication and discussion, providing subject matter, assigning and collecting assignments online, providing information about values and campus activities, and also announcements too. With a design model that is easily accessible and not boring. To support this thesis, the method of data collection is done by observation, interviews, and literature study. This writing aims to develop a learning management system that can be accessed via internet, fully managed by administrators, used by lecturers, and also students. So that learning becomes precise, fast, and accurate.

Abstract

Pada saat tidur hormone pertumbuhan diproduksi oleh tubuh bayi tiga kali lebih banyakdibandingkan saat bayi terbangun. Karena saat tidur pertumbuhan otak bayi mencapai puncaknya, makatidur nyenyak sangat penting bagi pertumbuhan bayi. Dengan jumlah responded 285 bayi. Diperoleh data51,3% bayi mengalami gangguan tidur, 42% bayi tidur malam kurang dari 9 jam. Alat monitoring inidigunakan untuk memantau bayi yang sedang tidur dengan memanfaatkan sensor Load Cell untukmendeteksi keberadaan bayi dan sensor suara untuk mendeteksi tangisan bayi, Node MCU ESP 8266sebagai pusat kendalinya dan platform IoT Blynk sebagai antarmuka pengguna yang terhubung ke jaringaninternet. Alat monitoring bayi saat tidur berbasis IoT dengan mikrokontroler Node MCU ESP 8266 telatselesai dibangun dan dapat bekerja dengan baik untuk memantau keberadaan bayi dan mendeteksi 2kgmaka alat akan mengirimkan notifikasi “Bayi Tidak Di Tempat” dan Ketika berat terdeteksi 2kg makaalat akan mengirimkan notifikasi “Bayi Tidur”. Sensor suara dapat mendeteksi sumber suara dengan jarak0 – 50 cm. Ketika sumber suara berjarak 0 – 50 cm maka alat akan mengirimkan notifikasi “Bayi Menangis”dan Ketika jarak sumber suara 50 cm maka suara tidak akan terdeteksi dan alat tidak mengirimkannotifikasi apapun ke aplikasi Blynk.

Abstract

Micro, Small, and Medium Enterprises (MSMEs) are the main drivers of Indonesia's economic growth, but many face challenges in adopting digital technology. This study aims to develop and evaluate the impact of the BERKEMBANG.ID digital platform in enhancing the capacity of MSMEs in Depok City, in line with achieving Sustainable Development Goal (SDG) 8. Using a mixed-methods approach, the study involves 100 MSMEs with a focus on three main indicators: digital knowledge (human resources), operational efficiency, and sales performance. The results show a significant improvement in MSMEs' capacity after using the BERKEMBANG.ID platform. Digital literacy among MSMEs increased from 40% to 75%, operational efficiency rose from 45% to 80%, and sales performance increased from 50% to 85%. These improvements were supported by the platform’s features, such as digital training modules, analytical dashboards, and marketing tools, which effectively addressed key challenges faced by MSMEs, including limited digital skills and market access. This study highlights the transformative role of digital platforms in empowering MSMEs and the importance of tailored digital solutions to meet their specific needs. By enhancing digital technology adoption, BERKEMBANG.ID not only improves MSME performance but also supports inclusive and sustainable economic growth. Future research could focus on replicating this platform in other regions and integrating advanced analytics to optimize its impact.

Abstract

Piezoelectric energy harvesters (PEHs) have attracted considerable attention as an alternative approach for converting ambient mechanical energy into electrical power, particularly under low-speed wind conditions. In this study, the performance of a micro-windmill-driven piezoelectric wind energy harvesting system is experimentally investigated with emphasis on the effects of wind speed and mechanical configuration ratios. Experiments were conducted in a controlled wind tunnel environment at wind speeds of 6, 7, and 8 m/s to represent low to moderate airflow conditions commonly encountered in practical applications. Three mechanical configuration ratios, namely 1:3, 1:2, and 1:1, were evaluated to assess their influence on the dynamic response and electrical output of the piezoelectric element. The alternating voltage generated by the piezoelectric harvester was rectified, and the output voltage–time characteristics were recorded over a 60 s testing period using a data acquisition system. The experimental results demonstrate that increasing wind speed significantly improves both the voltage rise rate and the achievable steady-state voltage for all tested configurations, indicating enhanced mechanical excitation and energy conversion efficiency at higher airflow velocities. Among the configurations examined, the 1:1 ratio consistently exhibits the highest output voltage and the fastest response, particularly at wind speeds of 7 and 8 m/s, suggesting an optimal mechanical–electrical coupling. The 1:2 configuration shows comparable performance at lower wind speeds, while the 1:3 configuration produces substantially lower voltage output throughout the test duration, reflecting reduced energy transfer effectiveness. Overall, the findings highlight the importance of mechanical configuration and wind speed in determining the performance of piezoelectric wind energy harvesters. The results provide useful design guidelines for optimizing PEH systems intended for self-powered sensors and other low-power electronic applications operating in low-speed wind environments.
