Peralatan elektronik hampir tidak dapat lepas dari kehidupan manusia untuk meningkatkan kemudahan dan kenyamanan dalam pemenuhan kebutuhannya. Aktifitas sehari-hari banyak dilakukan melalui smartphone sebagai alat yang hampir selalu dalam genggaman. Saat ini banyak alat elektronik yang dikendalikan hanya dengan menekan tombol remote. Perkembangan teknologi microcontroller seperti Arduino dapat diintegrasikan dengan alat yang lain, bukan hanya dengan robot saja. Penelitian ini membuat smartphone terhubung dengan mikrokontroler arduino yang digunakan sebagai pengendali alat elektronik. Obyek yang digunakan adalah mobil remote control mainan (RC Car). Metode penelitian yang dilakukan adalah studi literatur dan experiment. Arduino diprogram menggunakan bahasa C untuk menjalankan motor supaya bergerak sesuai dengan data masukan yang dikirimkan melalui Android. Penelitian ini menghasilkan prototype model sebuah alat elektronik yang dikendalikan dengan smartphone Android melalui koneksi bluetooth. Hasil pengujian menunjukkan bahwa kecepatan pairing Android-Arduino lebih dipengaruhi versi android dibandingkan hardware yang terpasang. Jarak antara Arduino-Android tidak berpengaruh besar terhadap kecepatanproses pairing.Electronic equipment can hardly be separated from human life is being used to improve the ease and comfort in the fulfillment of their needs. Daily activities mostly done via smartphone as a device that is nearly always in hand. Today, many electronic devices are controlled simply by pressing the remote button. Technological developments such as the Arduino microcontroller can be integrated with other tools, not only with robots. The objective of this research is to make a smartphone connected to Arduino microcontroller as the electronic appliance controller. Object that was used is a car remote control toys (RC Car). The research method conducted was literature study and experiment. Arduino was programmed using C language to run the motor to move according to the input data that was sent through the android. This research resulted in prototype model of an electronic device that is controlled by android smartphone via a Bluetooth connection. Test results showed that the speed of pairing Android-Arduino was influenced more by the android version than the installed hardware. The distance between the Arduino-Android did not greatly affect the speed of the pairing process.
The community has widely used the IoT tool because it makes it easy for users in various sectors. The implementation of IoT does not only require connectivity and devices but also requires a server. Servers that are accessed by many devices will have more and more computing processes on the server. The computing process on the server requires a high-performance but small-sized server device that is easy to connect with other devices. Raspberry Pi, known as an IoT server, is a computer with a small size, cheap, and very energy efficient. The parallel machine was built based on Raspberry Pi using parallel computing technology to have high performance. Nowadays, one of the parallel computing tools is Apache Hadoop. This research using clusters method with four pieces of Raspberry Pi with parallel computing technology using Apache Hadoop tools. Testing is done using Siege tools. The number of requests that used to test web server performance in this research was 10, 50, 100, and 150. The most optimal results are on requests by 50 with an increase of about 260% from a single node to cluster in the measurement of transactions, transaction rates, and throughput. Testing with 150 requests can only increase by 50% to 60%.
Magelang Regency's Dusun Dlinggo, Ngadirejo Village, Tegalrejo District, has become a center for traditional Eid cakes, namely semprong. The month of Ramadan sees the highest demand, with no more orders being taken even in the middle of the month. This community service aims to empower MSMEs by increasing demand for semprong cakes throughout the year through digital marketing and online sales. Through training and assistance in product design, packaging, and management of e-commerce websites and social media, the community is actively involved in the implementation of program. In comparison with before program, the results of measuring partner knowledge of digital marketing increased by 49%.
E-learning is pervasive in higher education, serving as a handy training option in today's hectic culture. Despite being a widespread phenomenon in both study and practice, e-learning is still far from being utilized successfully in any setting. This is due to a lack of study of the learners' point of view as well as insufficient thinking on the ramifications for the teachers. The first part of this research is a survey of university students' opinions and experiences with e-learning. The findings are both unexpected and expected: first, despite seeing e-learning as a promising future trend, students are still unsure of what it means and have only a limited understanding of its capabilities. Second, despite widespread adoption, there is still a sizable minority of students who have never used e-learning and are uninterested in doing so. Third, while e-learning appears to have more benefits than drawbacks, there are still many areas where it may be improved to make it truly effective. We offer some managerial implications for instructors and educational organizations based on these findings.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
