Abstract

This study proposes improving the performance of a fixed-axis multistage Savonius wind turbine by integrating a sixbladed guide vane. Guide vanes aim to direct the incoming wind towards the blades of the Savonius wind turbine so that it can increase the performance value of the turbine itself. There are two methods, the first method is computational fluid dynamics (CFD) simulation to evaluate the best performance guide vane angle variations. The second method is implementing real conditions using 3 m/s until 4.2 m/s wind speed. The implementation of the guide vane to the wind turbine will consider four (4) variants of angles (0°, 20°, 40°, and 60°). The purpose of testing with four kinds of guide vane angles is to find out which guide vane angle can provide the best results among other guide vane angles. This research proposed the initial design of the guide vane addition to the multistage Savonius wind turbine with a fixed rotary axis. From the CFD simulation, the implementation of a guide vane can improve the performance of the multistage Savonius wind turbine with a fixed rotary axis. On the other hand, for the proposed initial design in this research, the 20° angle of guide vane gives the best result compared to the 0°, 40°, 60°, and without guide vane.

Abstract

SMA Harapan Kasih merupakan salah satu SMA yang berlokasi di kota Bandung yang sangat peduli dengan literasi di bidang komputer untuk para siswanya. Saat ini SMA Harapan kasih memiliki keterbatasan dalam pengembangan kemampuan komputer bagi para siswanya di bidang desain 3D dikarenakan tidak adanya peralatan dan tenaga pengajar di bidang tersebut. Pelatihan ini bertujuan untuk meningkatkan keterampilan desain 3D siswa SMA Harapan Kasih Bandung melalui penggunaan perangkat lunak ThingkerCAD dan printer 3D. Metode pelatihan melibatkan sesi teori dan praktik yang diikuti oleh 60 siswa dari berbagai kelas. Hasil evaluasi menunjukkan peningkatan signifikan dalam kemampuan siswa dalam mendesain dan mencetak model 3D. Pelatihan ini tidak hanya meningkatkan keterampilan teknis tetapi juga memotivasi siswa untuk lebih mendalami teknologi desain 3D.   Harapan Kasih High School is one of the high schools located in Bandung that is very concerned with computer literacy for its students. Currently, SMA Harapan Kasih has limitations in developing computer skills for its students in the field of 3D design due to the lack of equipment and teaching staff in this field. This training aims to improve the 3D design skills of SMA Harapan Kasih Bandung students through the use of ThingkerCAD software and 3D printers. The training method involves theory and practice sessions attended by 60 students from various classes. The evaluation results showed a significant increase in students' abilities in designing and printing 3D models. This training not only improves technical skills but also motivates students to further explore 3D design technology.

Abstract

Augmented Reality (AR) technology has the ability to dramatically change business and education through greater efficiency, competitiveness, and client services. By offering interactive guides, contextual learning modules, and virtual lab tours, AR can increase the efficacy of learning in a database laboratory. Furthermore, gamified learning possibilities and real-time collaboration tools in AR have the potential to boost student comprehension and engagement, especially for new and prospective students. Expanding its application, augmented reality can significantly affect global trade. A PwC estimate suggests that productivity increases in AR might increase global GDP by $1.5 trillion by 2030. Businesses who employ AR for remote assistance and training have seen up to 40% boosts in productivity, according to Deloitte's research. Furthermore, according to MarketsandMarkets, AR boosts competitiveness by providing immersive customer experiences that raise customer happiness and engagement. These results show how AR is transforming a number of industries

Abstract

The information system in the form of part-time job vacancies in the scope of study programme X is one of the containers that is needed both from employers (lecturers) and job seekers (students). The information system regarding part-time work in study programme X is able to provide convenience for employers in finding workers who are in accordance with what they need and also provide opportunities in the form of experience for job seekers in study programme X. This research work begins with a system design design with predetermined limits based on observations of the X study programme which is used as a benchmark. The development of this information system is determined using the prototype development method because of the short development time and must be able to be used while the development itself takes place. After obtaining the limitations from the observation results, a database system design will be carried out for the purposes of this research information system application which will be applied to the system. The next step is the information system design process which is broken down into two parts, namely the front-end and back-end parts. For testing this information system itself using the black box testing method with the main target, namely the original user as the respondent

Abstract

Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan literasi teknologi siswa SMA dalam bidang telepresence. Telepresence merupakan teknologi penting di era digital karena untuk meningkatkan koneksi antara manusia yang berjarak jauh. Pemahaman terhadap teknologi telepresence sangat penting dan relevan saat ini. Hal ini mengingat peranannya yang terus berkembang dalam bidang pendidikan, kesehatan, industri, hingga komunikasi global. Kegiatan ini melibatkan siswa kelas XI IPA dan XI IPS di SMA Harapan Kasih Bandung, dengan total peserta pengabdian sebanyak 34 siswa. Materi yang diberikan mencakup pengertian telepresence, contoh implementasi dalam kehidupan sehari-hari, serta penjelasan konsep dan implementasinya. Evaluasi hasil pengabdian dilakukan dengan cara memberikan pretest dan post-test yang berfungsi untuk mengukur peningkatan pemahaman peserta pengabdian. Hasil pretest menunjukkan bahwa hanya 5 dari 34 siswa (15%) yang memahami konsep dasar telepresence, dan 9 siswa (26%) dapat menjawab soal dengan benar. Setelah sesi pembelajaran, hasil post-test meningkat secara signifikan: 29 siswa (85%) memahami konsep telepresence, dan 27 siswa (79%) mampu menjawab soal-soal teknis dengan benar. Selain terjadi peningkatan pengetahuan pada siswa, tetapi terjadi juga peningkatan minat siswa terhadap teknologi telepresence.
