Abstract

Industry is one of the economic sectors that plays a role in processing environmental resources into products with higher utility values. This process includes design activities, industrial engineering, and service provision. Matra Abadi Workshop, a manufacturing industry that in its operations produces harmonic currents in the electric power system network, especially in low-order harmonics such as 3rd, 5th, 7th, 9th, and 11th. To reduce the negative impact of harmonics on the power system, the use of passive harmonic filters is required. Among the types of filters used, single tuned filters are a common choice because of their simple construction and effectiveness in reducing certain order harmonics that exceed the IEEE 512–2014 standard limits. This study discusses the implementation of both types of filters in a manufacturing industry environment. The harmonic reduction process is carried out through filter design and testing using Matlab/Simulink software-based simulations. The simulation results show that after the application of passive filters, the harmonic current levels in all load configurations were successfully suppressed to within the IEEE 512–2014 standard limits. The reduction in Total Harmonic Distortion (THDi) after the application of the single tuned filter was recorded in the range of 17.86% to 11.06%. In addition, there was an increase in the power factor from 0.68 before the filter was installed to 0.91 after the installation, which indicates an improvement in the overall power system performance.

Abstract

This research aims to create a learning multimedia application that can be used by students in learning. The method used is development research from Jan Van De Akker with formative evaluation from Martin Tessmer. The research stage consists of four stages, namely the preliminary research stage, prototype, summative evaluation, and systematic reflection and documentation. Based on user assessment, the learning multimedia is practical to use with a practicality level of 83% and is included in the good category. The effectiveness of multimedia at the summative evaluation stage is based on the post-test results. The results of the student posttest stated that 9 out of 12 students scored ≥75, meaning that 75% of the participants passed and this multimedia is effective. The results showed that the learning multimedia application can improve the higher-order thinking skills of students.

Abstract

Kegiatan pengabdian kepada masyarakat ini dilaksanakan di Desa Sampali, Kecamatan Percut Sei Tuan, Kabupaten Deli Serdang, dengan tujuan meningkatkan produktivitas dan nilai ekonomi pisang Cavendish melalui penerapan teknologi kultur jaringan. Latar belakang kegiatan ini berangkat dari kondisi petani lokal yang masih mengandalkan metode budidaya konvensional dengan bibit yang tidak seragam dan rentan penyakit, sehingga produktivitas dan kualitas hasil panen rendah. Metode pelaksanaan menggunakan pendekatan Participatory Rural Appraisal (PRA) yang menekankan keterlibatan aktif petani dalam seluruh proses, meliputi tahap persiapan, pelatihan, implementasi, serta monitoring dan evaluasi. Pelatihan yang diberikan mencakup pembuatan bibit unggul berbasis kultur jaringan, pengelolaan hama terpadu, pengemasan produk, dan strategi pemasaran digital. Hasil kegiatan menunjukkan peningkatan signifikan dalam aspek pengetahuan dan keterampilan petani, dengan rata-rata peningkatan pemahaman mencapai 85%. Bibit hasil kultur jaringan menunjukkan tingkat keberhasilan tumbuh sebesar 92% di lapangan, sementara produktivitas lahan meningkat hingga 32% dibandingkan metode sebelumnya. Selain itu, pendapatan petani meningkat sebesar 22% berkat optimalisasi hasil panen dan diversifikasi produk olahan pisang. Kegiatan ini juga memperkuat jejaring kerja sama antara kelompok tani, koperasi desa, dan pelaku usaha lokal. Secara keseluruhan, penerapan teknologi kultur jaringan terbukti efektif dalam meningkatkan efisiensi produksi, kemandirian petani, dan keberlanjutan ekonomi lokal di Desa Sampali.

Abstract

This study is dedicated to the creation of geometry transformation learning media through the utilization of Mobile-Based App Inventor and a subsequent comprehensive evaluation of its influence on student academic performance. The research adopts a meticulously structured Research and Development (R&D) methodology, encompassing critical stages such as analysis, design, development, implementation, and evaluation. The culmination of this research journey unveils compelling evidence that underscores the transformative potential of the developed learning media. Through quantitative and qualitative assessments, this study unearths a significant enhancement in students' grasp of the intricate concepts inherent to geometry transformation. The outcomes of this research illuminate the pivotal role of technology, particularly the Mobile-Based App Inventor, in shaping contemporary pedagogical landscapes. The learning media serves as a testament to the symbiotic relationship between innovation and education, offering an engaging and effective resource to empower students in their quest for mathematical proficiency and analytical prowess.
