Abstract

Penelitian ini bertujuan untuk merancang data logger, yaitu sebuah perangkat yang dapat mengukur, menghitung dan menyimpan data tenaga listrik yang dihasilkan oleh panel surya secara terus menerus dalam jangka waktu tertentu. Data diperoleh dari hasil pengukuran tegangan dan arus listrik pada panel surya. Tegangan dan arus  listrik ini ditangkap oleh sensor, kemudian diolah menggunakan microcontroller. Selanjutnya data disimpan dalam media penyimpan berupa SD/MMC card yang dapat diunduh dan dianalisa lebih lanjut menggunakan personal computer, sehingga dapat diketahui nilai energi listrik. Dari percobaan yang dilakukan, ternyata data logger dapat bekerja dengan cukup baik. Dari hasil pencatatan didapatkan bahwa nilai tegangan mempunyai penyimpangannya 4.49 %, sedang untuk nilai arus listrik penyimpangannya 2.45 %. Nilai tegangan yang didapatkan relatif besar bila dibandingkan dengan pengukuran dengan menggunakan peralatan ukur yang presisi, Besarnya kesalahan ini antara lain disebabkan penggunaan komponen resistor pembagi tegangan yang memiliki toleransi yang besar. Dengan menggunakan resistor metal film yang mempunyai toleransi lebih kecil, nilai tegangan yang didapatkan akan lebih presisi.Kata kunci : data logger, microcontroller, listrik tenaga surya

Abstract

Axle counter is a railway detection equipment producing wave frequencies to count the number of axles passing over the track. The existence of a mismatch between the initial and final count numbers usually leads to a red signal and this can prevent the formation of a travel route. The components of axle counter are often damaged by lightning strikes both directly and through the distribution of excessive currents due to a poor grounding system. However, these excessive currents can be safely grounded without damaging the components through the application of a good grounding system. Therefore, this research aimed to plan an effective grounding system to anticipate the incidents using the Wenner method. Some requirements such as soil type, depth, and electrode rod diameter were used in the process to determine the appropriate resistance value. The design was made based on the simulations that closely resembled real field conditions using Aspix software and grounding resistance values were also measured directly on the field to determine the discrepancies between the planning and actual conditions.
