Abstract

Along with technological advances in the digital era like today, which is growing faster, it has an impact on many fields. One field that has used a lot of technological developments is the CPNS Test which is based on the CAT (Computer Assisted Test) and uses many a lot of laptop/computer devices to support the implementation of the test. The many uses of computers, especially during the recruitment test, influence the quality of electrical power due to the typical character of the PC/laptop load, which is a non-linear single-phase load which results in neutral currents or currents containing harmonics. This is because the load on the pc/laptop has electronic components such as semiconductors where there is a switching process that creates an impure sinusoidal wave that causes harmonics. In the case study, the implementation of the CPNS CAT with the use of PC/laptop devices will certainly cause a fairly high THD and affect the electric current/power source. The thing that needs to be considered with a high THD and the supply of electricity from the generator is the effect on the performance of the generator and the influence of the generator’s lifetime. Briefly, the loading of the data is to reduce the derating generator set by 6,717 kVa so that the safe loading is 23.28 kVa with a maximum capacity of 30 kVa generator. Synchronous generator loading is recommended at 81% of its nominal value with a current THD of 50%.

Abstract

UMKM Hasanudin, yang berdiri sejak tahun 2013 dan telah berkembang menjadi tujuan Kuliner dan istirahat sejenak bagi warga malang, terutama karyawan dan pelajar. UMKM ini menjadi mitra utama dalam proyek pengabdian ini yang bertujuan untuk meningkatkan konektivitas dan mobilitas di lokasi tersebut. Proyek ini fokus pada instalasi PLTS off grid dengan sistem PLTS Foldable untuk mengatasi tantangan keterbatasan akses listrik, terutama di lokasi UMKM. Keterbatasan sumber energi dikarenakan daya listrik terpasang sebesar 900kwh. Kebutuhan daya tersebut hanya dapat memenuhi kebutuhan UMKM saja, sedangkan kebutuhan pelanggan untuk charging HP dan Laptop sering kali membuat trip sumber listrik UMKM. Dengan menyediakan fasilitas pengisian daya yang handal untuk perangkat elektronik seperti ponsel dan laptop, proyek ini memungkinkan pengunjung untuk tetap terhubung dan berkomunikasi selama berada di kawasan. Penerapan charging station portabel ini menyediakan solusi praktis dan efisien, meningkatkan kenyamanan pengunjung dengan memastikan mereka dapat tetap terhubung selama berada di kawasan. Pemanfaatan Charging Station portable juga termasuk dalam salah satu Langkah hilirisasi produk penelitian mahasiswa Jurusan Teknik Elektro yang berupa Pembangkit Listrik Tenaga Surya Portable.
