Abstract

Energi  listrik  merupakan  kebutuhan  pokok  yang  sangat  penting  bagi  kehidupan  manusia,  dimana  semua  aktifitas manusia  berhubungan  dengan  energi  listrik.  Listrik sebagai sumber kehidupan masyarakat  selain  berfungsi  sebagai  penerangan,  juga  berfungsi  sebagai  energi  dalam  mengembangkan  segala  usaha  dan aktifitas sehari-hari. Pada beberapa daerah di Indonesia masih ada kawasan yang belum mendapatkan energi listrik seperti di Kelurahan Batu Gadang Kecamatan Lubuk Kilangan Kota Padang khususnya pada kawasan Ngalau Baribuik. Melihat kondisi di sekitar Ngalau Baribuik, masih ada potensi untuk membangun PLTMH sekitar 5KW. Artikel ini membahas mengenai pembangunan PLTMH yang dimulai dari studi kelayakan, detail engineering design, pembuatan turbin, pengerjaan sipil dan elektrikan. Metode yang digunakan dalam pembangunan system kelistrikan di Ngalau Baribuik dengan menerapkan metoda ilmiah

Abstract

Perkampungan Ngalau Bribuik terletak di kelurahan Batu Gadang Kecamatan Lubuk Kilangan Kota Padang. Pada daerah ini terdapat lebih dari 24 kepala keluarga yang sampai saat ini masih belum menikmati energi listrik dari PLN. Upaya memenuhi kebutuhan terhadap energi listrik, masyarakat memanfaatkan Pembangkit Listrik Mikro Hidro dengan kapasitas terpasang 10 Kw. Namun kapasitas ini masih belum bisa memenuhi kebutuhan masyarakat sehingga banyak keluarga yang belum menikmati energy listrik. Dari hasil survey yang dilakukan, instalasi listrik terpasang di rumah warga juga masih bisa dikatakan belum layak pakai. Menyikapi hal tersebut, upaya yang dilakukan oleh Tim pengabdi adalah dengan melakukan kajian secara menyeluruh terhadap instalasi terpasang di rumah warga untuk melihat kelayakannya. Berdasarkan hasil kajian yang dilakukan, tim pengabdi melakukan perbaikan dan penggantian komponen instalasi listrik serta penataan ulang kembali instalasi yang ada di rumah warga. Selain dari itu, tim pengabdi juga melakukan pemasangan instalasi baru pada beberapa rumah warga di Perkampungan Ngalau Baribuik.

Abstract

The Project Based Learning (PjBL) model is a learning strategy where students work on projects that help solve community/environmental problems. The ability to think at a higher level is a life skill that students must develop to face the challenges of life in the 21st century. One of the abilities at a high level is the ability to think creatively. The aim of this research is to analyze the effect of project-based learning on creative thinking skills. This research method is meta-analysis using a sample of 16 articles from various article sources. The research was conducted using quantitative methods using the OpenMEE application as a measure of effect size. The results of the meta-analysis show that the application of the PjBL model significantly influences students' creative thinking abilities as seen from various subjects and levels of education, from elementary school to college. The average effect size results are in the very high category, which means that the application of the PjBL model in learning influences creative thinking abilities

Abstract

Education at the high school (SMA) and vocational school (SMK) levels faces challenges in preparing creative and competent students. To address these challenges, a combination of technology is needed in the fields of science, mathematics, and engineering. A study on the implementation of STEM (Science, Technology, Engineering, and Mathematics) in learning in Indonesia. To test its effectiveness, a meta-analysis was conducted which included 25 articles published between 2018 and 2023. The findings showed that STEM learning has a significant role in improving student learning outcomes with an overall effect size of 6,89. Based on the data analysis of the application of the STEM approach, it can develop the ability to solve problems rationally, conduct research, question, collaborate, criticize, analyze and can also improve the ability to access information, adapt to change, make decisions, produce, be responsible, show curiosity, interact in a social and cultural context, and develop leadership and entrepreneurship traits in students. The STEM approach provides a solid foundation for developing a variety of skills and attitudes that are important in facing the challenges and demands of the modern world of students.

Abstract

This research revolves around the challenges faced by students in aligning their career orientation with demands and changes, as many traditional jobs are threatened by AI technology. The aim of this study is to identify trends in the transformation of students' career orientation in the era of Artificial Intelligence (AI), map the career challenges for students in the AI era, analyze the skills and competencies required, and assess the role of educational institutions in supporting this career transformation. The research method applied in this study is a systematic literature review. The initial stages involve collecting literature sources from scholarly databases and proceeding with a screening process to select literature relevant to the research focus. Finally, in-depth analysis of selected literature is conducted to identify patterns, trends, and key points related to the research topic. The results of the study describe that the development of AI technology has a significant impact on students' career orientation in higher education. Furthermore, students also face career challenges such as competition with technology, uncertainty about future employment, and skills gaps. To address these challenges, students need to develop technical AI skills, ethical AI understanding, problem-solving abilities, and continuous learning skills to succeed in the AI job market. On the other hand, higher education institutions should play a proactive role in addressing these challenges by developing relevant curricula, organizing training sessions, collaborating with industries, and enhancing AI learning facilities. Further research is suggested to focus on the implementation of these strategies in the specific context of higher education institutions and evaluate their impact on student career preparedness in the evolving AI era.

Abstract

Sektor energi sangat berpengaruh terhadap aktifitas masyarakat seperti kegiatan rumah tangga, sosial budaya, industri, perdangan, dll. Pada tahun 2021, meskipun rasio elektrifikasi Provinsi Sumatera Barat sudah mencapai 98.81%, penyediaan energi listrik tetap menjadi salah satu prioritas pembangunan. Sebenarnya Indonesia memiliki potensi cadangan energi baru terbarukan yang besar seperti radiasi matahari, energi angin, energi air, biomassa, dll. Namun pengembangan teknologi pembangkit energi baru terbarukan belum maksimal karena tingginya biaya investasi dan perawatan. Penelitian ini bertujuan untuk melakukan rancang bangun sebuah pembangkit listrik tenaga piko hidro. Berdasarkan hasil analisis karakteristik aliran dan kondisi lapangan jenis turbin air yang sesuai untuk head dan debit yang rendah adalah turbin aliran silang (cross flow). Pembangkit Listrik Piko Hidro ini diharapkan mampu memenuhi kebutuhan energi bagi beberapa kepala keluarga sehingga dapat meningkatkan produktifitas kerja, tingkat pendapatan dan kesehjateraan warga pada daerah pedalaman.

Abstract

Motor induksi satu-fasa digunakan dalam banyak aplikasi rumah tangga dan industri. Namun, ada tantangan tersendiri dalam mengoperasikan motor induksi satu-fasa. Salah satu persoalan yang muncul adalah besarnya arus stator pada saat pengasutan. Dalam artikel ini, metode pengasutan motor induksi satu-fasa yang menggunakan metode tahanan biner disajikan. Selain itu, karakteristik motor induksi seperti tegangan, arus, kecepatan, dan suhu dipantau melalui antarmuka visual studio. Beberapa komponen penting digunakan dalam sistem ini, seperti sensor tegangan ZMPT101B, sensor suhu DS18B20, sensor kecepatan FC-33, sensor arus ACS712, bluetooth HC-05, lima relay, dan empat resistor 15 Ω. Hasil eksperimen yang menunjukkan bahwa metode tahanan biner efektif dalam mengurangi arus asut motor induksi. Suatu antarmuka yang dikembangkan dapat memantau karakteristik motor induksi.
