Abstract

SMA Global Prima Medan memiliki klub robotik, namun masih menghadapi keterbatasan sumber daya manusia yang berkompeten untuk memberikan pelatihan merakit robot. Permasalahan ini berdampak pada minimnya pemahaman siswa terkait komponen elektronik, bahasa pemrograman, dan keterampilan merakit robot. Kegiatan pengabdian masyarakat ini bertujuan untuk meningkatkan kemampuan siswa dalam bidang robotik melalui pelatihan perakitan Robot Line Follower. Mitra dalam kegiatan ini adalah 80 siswa SMA Global Prima Medan. Metode pelaksanaan menggunakan pendekatan partisipatif dengan tiga tahapan utama, yaitu penentuan materi dan komponen, pelaksanaan pelatihan, serta evaluasi pemahaman siswa. Hasil kegiatan menunjukkan bahwa siswa memperoleh peningkatan signifikan dalam pemahaman komponen (95%), keterampilan merakit robot (80%), serta cara kerja sensor infrared (80%), meskipun pemahaman bahasa pemrograman C++ masih rendah (20%). Evaluasi pelaksanaan pelatihan juga memperlihatkan tingkat kepuasan yang sangat tinggi, baik terhadap pemateri, instruktur, maupun fasilitas yang digunakan. Kegiatan ini membuktikan bahwa pelatihan robotik mampu menumbuhkan antusiasme siswa serta memberikan kontribusi nyata dalam memperkuat keterampilan teknologi di tingkat SMA.

Abstract

The wireless solar power transfer (WSPT) system is impacted by solar radiation that arrives on the surface of the solar module. The objective of the research is to evaluate the performance of the WSPT system under a shadowing situation. The method of this research is that the solar module and WSPT are modeled and simulated using MATLAB SIMULINK. Three solar modules with different degrees of solar irradiation are subjected to it. The research results indicate that to meet the system frequency of 50 Hz and match the frequency of both coils, the inductance of the transmitter and receiver coils, which is 0.1689 H, should be connected in parallel to a capacitor of 60 µF. It shows that the three solar modules connected in series have an output voltage of 177 V. It shows that the WSPT system and solar modules' performance are impacted by the shadowing situation. Higher shadowing levels will lessen the amount of sunlight that reaches the solar modules' surface. It implies that both the WSPT system's performance and that of the solar modules will decline concurrently.

Abstract

Pests are a major challenge for rice farmers because they can reduce the quality of the harvest. Manual pest control which is still widely used tends to be less effective and requires large costs and energy. With the advancement of technology, there is a more effective innovative solution, namely Node MCU-based devices that utilize renewable energy, such as solar cells. This device is able to repel pests automatically and is environmentally friendly, making it a more modern and sustainable alternative. This study aims to design a Node MCU-based rice pest repellent system with energy from solar cells. The results of this study showed that the tool ran smoothly, indicated by the absence of errors when turning on the tool, and had 2 failures during the command execution process from 20 tool trials, therefore the percentage of resistance to malfunction of 90% was obtained from the number of failed trials multiplied by 100, and the results multiplied by the total number of trials. It can be concluded that the tool functioned normally during the trial in the rice field area.

Abstract

Watering the Garden by Using Solar Cells. Guided by Zahir Zainuddin and Adriani. Solar Cells are devices composed of semiconductor materials that can convert sunlight into electricity directly. Often also used the term photovoltaic or photovoltaic. In this design, the automatic garden watering using solar cells requires timer equipment, BCU, rain sensor, relay, battery/battery, and inverter. The purpose of this design is to know the performance of plant watering design by using solar cells as a source of stress and to know the control system and rain sensor in maximum watering of plants so that later can be applied to the next design and society. Garden Water Purification Test Using an Unsaturated Solar Cell on 31 December 2017 produced a Voltage of up to 18 volts with 1.5 ampere Current, and on 14 December 2017 made a Voltage of up to 17.5 volts with 1.4 ampere Flow. At the time, the load voltage issued by the battery of 11.5 V and issued a current of 5.73 A, and the voltage released by the inverter was 214 V and issued a current of 1.05 A. While the middle of the operation is also measured, the voltage is discharged by an 11.80 V battery with a current of 7.80 A and an output voltage of an inverter of 221 V and an output current of 0.81A.

Abstract

Tujuan Pengabdian kepada Masyarakat ini adalah untuk menaikkan pendapatan masyarakat Kec.Pagar Merbau Kabupaten Deli serdang. Kreatifitas dan inovasi yang erat kaitannya dengan teknik sipil perlu selalu dikembangkan terus untuk memenuhi. Dengan Batu bata yang kuat dan mampu menahan beban menjadi komponen yang penting dalam pembangunan. Batu bata konvensional yang ada sekarang adalah Batu bata yang masih berwarna merah. Itupun batu bata tersebut tidak tahan, untuk itu tim pengabdian akan membuat suatu inovasi baru yaitu dengan membuat batu bata berwarna yang anti jamur, hal ini agar masyarakat sekitar bisa memproduksinya dan juga menjualnya ke pasaran sehingga halnya otomatis dapat menaikkan pendapatan masyarakat sekita Kec,Pagar Merbau Kabupaten Deli Serdang. Hal yang sebenarnya dapat dilakukan adalah dengan mencampur pewarna ke dalam batu bata , sehingga batu bata yang sudah dibakar nanti akan menimbulkan warna baru, sesuai dengan pewarna yang akan digunakan dan juga pembakarannya harus lebih lama yaitu selama 12 jam sehingga akan lebih tahan nantinya batu bata warna yang dihasilkan. Dan hal ini sudah diuji selama 6 bulan untuk membandingkan batu bata biasa yang dibakar selama 8 jam dengan batu bata warna yang lebih estetik dengan pembakaran 12 jam dan mendapatkan hasil yang lebih kuat dan tidak berubah bentuk maupun warna yaitu dengan batu bata warna yang anti jamur dan tidak berlumut.

Abstract

The advancement of telemedicine and robotic surgery has led to increased interest in haptic feedback systems, which enhance the surgeon's ability to perform remote procedures. Haptic technology provides tactile sensations, allowing surgeons to feel the instruments' interactions with tissues, thus improving precision and control during surgery. This research aims to implement haptic feedback in robotic surgical systems, evaluating its impact on surgical performance and user experience during remote operations. The study seeks to determine whether incorporating haptic feedback can enhance the effectiveness and safety of robotic-assisted surgeries. A mixed-methods approach was employed, combining hardware development of a robotic surgical system with haptic feedback integration. Surgeons participated in controlled experiments to perform simulated surgical tasks with and without haptic feedback. Performance metrics, including task completion time, accuracy, and user satisfaction, were assessed. The implementation of haptic feedback resulted in a 30% reduction in task completion time and a 25% improvement in accuracy compared to non-haptic conditions. Surgeons reported higher satisfaction levels and increased confidence in performing procedures with the haptic-enabled system. The findings indicate that integrating haptic feedback into robotic surgical systems significantly enhances surgical performance and user experience. This research contributes to the growing body of knowledge in robotic surgery, demonstrating the potential of haptic technology to improve outcomes in remote surgical procedures.

Abstract

Teachers play a pivotal role in educating the nation, yet their financial well-being is often overlooked due to low financial literacy. Limited salaries are frequently consumed by immediate spending needs without planning for the future, leaving teachers vulnerable to fraudulent investment schemes or illegal online loans. This community service initiative aims to enhance teachers' financial literacy by introducing smart salary management strategies and future-oriented investment options. The program partnered with teachers from the Citra Mandiri Foundation School in Deli Serdang. The methodology employed included a preliminary survey, a workshop session, a personal budgeting simulation, and a final evaluation. Results indicated an improvement in participants' financial understanding following the training. Teachers are now able to create monthly budget allocations using sound financial formulas and understand legal investment instruments regulated by the Financial Services Authority (OJK). The initiative concludes that periodic financial education is crucial for fostering financial stability and professional peace of mind among educators.
