Abstract

Penelitian membahas tentang evaluasi penerangan tempat parkir kawasan Candi Borobudur yang beralamat di Jalan Badrawati, Borobudur, Kecamatan Borobudur, Kabupaten Magelang, Jawa Tengah. Tujuan yang diharapkan dari evaluasi penerangan tempat parkir yaitu menghasilkan penerangan yang sesuai standar yang berlaku sehingga dapat memberikan keamanan dan kenyamanan pengunjung. Metode yang digunakan yaitu metode komparasi, membandingkan hasil pengukuran dengan SNI 7391:2008, dan memberikan rekomendasi sistem penerangan ketika hasil evaluasi belum sesuai dengan standar. Hasil evaluasi menunjukkan bahwa penerangan tempat parkir Candi Borobudur belum se suai SNI, sehingga perlu dilakukan perencanaan ulang. Perencanaan ulang penerangan merekomendasikan penambahan lampu penerangan yang mulanya 6 lampu penerangan menjadi 18 lampu penerangan. Perencanaan penerangan menggunakan lampu nikkon S2266 230 W dan lampu philips BVP651 385 W. Hasil perencanaan dengan mengambil sampel  zona A3 dengan nilai illuminasi 7 lux, setelah dilakukan perencanaan menjadi 16,6 lux sehingga penerangan sudah sesuai dengan SNI 7391:2008.

Abstract

Transformers are vital components in electrical power systems. However, they are also susceptible to various types of failures, including thermal and electrical faults caused by the formation of electromotive force, which, if left unaddressed, may result in degradation of the oil insulation. One effective approach to mitigate such issues is to conduct feasibility testing and oil analysis, commonly known as Dissolved Gas Analysis (DGA), which examines the condition of the insulating fluid within the transformer. In this study, gas concentration levels were identified as follows: C₂H₄ = 9 ppm, CH₄ = 4 ppm, and C₂H₂ = 11 ppm. These values were visualized using the Duval Triangle Method, an established technique for analyzing gas content by measuring the concentration of three primary gases: Methane (CH₄), Ethylene (C₂H₄), and Acetylene (C₂H₂), all of which dissolve in the transformer oil. The advantage of this method lies in its ability to serve as an early fault detection tool for transformer oil. The analysis results indicated an electrical fault categorized as a High Energy Discharge in zone D2, identified by a single plotted point where the three gas lines intersect on the triangle diagram. This type of discharge is predominantly associated with Acetylene gas (C₂H₂) and is typically triggered by intense internal arcing within the transformer. The interpretation was further implemented using an automated data plotting system in GNU Octave, serving as a Transformer Fault Detection tool and computational software that utilizes the C++ programming language for data processing and visualization.
