Abstract

The purpose of this research is to know to know the influence of stator coil shape to performance (induced voltage and output power) of single phase axial flux permanent magnet generator. The method used is an experimental method. The population in this study is a unit of single phase axial flux permanent magnet generator. The sample in this study is the stator coil. Experiments were carried out by testing the performance of a single-phase axial flux permanent magnet generator in each variation the number of coil windings which had the 90 turns, 120 turns, and 350 turns. Experiments were carried out with no -load testing and with a resitive load that used 30 Watt incandescent lamps. The conclusion of this study shows that there is an influence from the number of coil windings on the performance (induced voltage and output power) of the generator. From three variations of the stator coil that used as sample, the highest performance is shown by the single phase axial flux permanent magnet generator which used the highest number of coil stator turns. The more number of turns, the better the performance of a single-phase axial flux permanent magnet generator.

Abstract

The purpose of this research is to know the influence of NdFeB permanent magnet dimensions and the distance of air gap on performance of single phase axial flux permanent magnet generator. In this research using quantitative approach with experimental method. Research subjects used, namely permanent magnetic generator axial flux with two rotor samples that have different magnetic dimensions and conducted air gap variation. The research data was collected by testing without load and testing with electrical load, to know the performance values of the generator in the form of induction voltage and electric power. The results showed that the induction voltage and electric power were affected by the magnetic dimensions and the distance of the air gap. These results indicate that the rotor with a magnetic surface area of 0.0058 m2 and 0.0034 m2 produces an induced voltage of 91.7 and 27.1 V, as well as a power of 14 and 2.8 W. Whereas, for variations in the air gap with the rotor magnetic surface area 0.0058 m2 and varied 2; 3; 4; 5; and 6 mm produces an induced voltage of 91.7; 89.0; 86.5; 80.2; and 68.5 V, and power of 14; 12; 10.9; 10.5; and 8.8 W. Thus, the use of a magnet ic dimension that is larger and in accordance with the size of the coil, as well as the use of a small air gap distance will result in a better induction voltage value. Abstrak Tujuan dari penelitian ini adalah untuk mengetahui pengaruh dimensi magnet permanen NdFeB dan jarak celah udara terhadap kinerja generator magnet permanen fluks aksial satu fasa. Pada penelitian ini menggunakan pendekatan kuantitatif dengan metode eksperimen. Subjek penelitian yang digunakan, yaitu generator magnet permanen fluks aksial dengan dua sampel rotor yang memiliki dimensi magnet berbeda dan dilakukan variasi celah udara. Pengumpulan data penelitian dilakukan dengan pengujian tanpa beban dan pengujian dengan beban listrik, untuk mengetahui nilai-nilai kinerja generator berupa tegangan induksi dan daya listriknya. Hasil penelitian menunjukkan bahwa tegangan induksi dan daya listrik dipengaruh oleh dimensi magnet dan jarak celah udara. Hasil tersebut menunjukkan bahwa pada rotor dengan luas permukaan magnet 0,0058 m2 dan 0,0034 m2 menghasilkan tegangan induksi sebesar 91,7 dan 27,1 V, serta daya sebesar 14 dan 2,8 W. Sedangkan, pada variasi celah udara dengan rotor luas permukaan magnet 0,0058 m2 dan divariasi 2; 3; 4; 5; dan 6 mm menghasilkan tegangan induksi sebesar 91.7; 89.0; 86.5; 80.2; dan 68.5 V, serta daya sebe sar 14; 12; 10,9; 10,5; dan 8,8 W. Maka, penggunaan dimensi magnet yang lebih besar dan sesuai dengan ukuran kumparan, serta penggunaan jarak celah udara yang kecil akan menghasilkan nilai tegangan induksi yang lebih baik.

Abstract

The purpose of this study is to determine the suitability of lightning protection system in University State of Jakarta campus A sector C with PUIPP 1983, the minister of labor legislation of the republic of Indonesia PER.02/MEN/1989, and SNI 03-7015-2004, based the importance of the lightning protector system. Method that used is evaluation description method. In collecting data, the main components of the lightning rod installation are observed, measuring earth resistance, and conducting connectivity tests if the channeling down is not visible, the data can then be processed mathematically which then compares the results with PUIPP 1983, regulation of the minister of labor of the Republic of Indonesia PER. 02 / MEN / 1989, and SNI 03-7015- 2004. Results of evaluation lightning protector system research showed that only Ki Hajar Dewantara building that obey with PUIPP 1983, the minister of labor legislation of the republic of Indonesia 02/MEN/1989, and SNI 03-7015-2004. The other buildings not obey with PUIPP 1983, the minister of labor legislation of the republic of Indonesia PER.02/MEN/1989, and SNI 03-7015-2004, caused main 195nticipat of lightning protection in these building is lost, broken, or the plan of lightning protector not macht with protection area needed. In other case few buildings of unj kampus A sector C that unprotected, the buildings are DE, E, F, L, L5 and K FIS. This things must be 195nticipate with add one active lightning protector at K FIS building with minimum radius 107,47m. Of course with notes to evaluate periodically especially if there is construction in the building on radius protection lightning protection system enhancements. Abstrak Tujuan penelitian ini adalah untuk mengetahui kesesuaian sistem penangkal petir Universitas Negeri Jakarta kampus A sektor C dengan PUIPP 1983, peraturan menteri tenaga kerja Republik Indonesia PER.02/MEN/1989, dan SNI 03-7015-2004, didasari pada pentingnya sistem penangkal petir. Metode yang digunakan adalah metode evaluasi deskriptif. Pada pengumpulan data, dilakukan observasi komponen utama instalasi penangkal petir, mengukur tahanan pentanahan, dan melakukan uji konektivitas apabila penyalur turun tidak terlihat, data yang di dapat lalu diolah secara matematis yang kemudian dibandingkan hasilnya dengan PUIPP 1983, peraturan menteri tenaga kerja Republik Indonesia PER.02/MEN/1989, dan SNI 03-7015-2004. Hasil penelitian evaluasi sistem penangkal petir eksternal menunjukkan hanya satu gedung pada UNJ kampus A sektor C instalasinya telah memenuhi dan sesuai dengan PUIPP 1983, peraturan menteri tenaga kerja Republik Indonesia PER.02/MEN/1989, dan SNI 03-7015-2004. Sedangkan, gedung lainnya belum memenuhi PUIPP 1983, peraturan menteri tenaga kerja Republik Indonesia PER.02/MEN/1989, dan SNI 03-7015-2004, hal ini dikarenakan pada gedung lainnya banyaknya komponen instalasi penangkal petir yang sudah tidak lengkap, rusak, serta perencanaan instalasi yang tidak sesuai dengan kebutuhan gedung. Selain itu terdapat beberapa wilayah UNJ kampus A sektor C yang belum terlindungi, diantaranya adalah Gedung DE, E, F, L, L5 dan K FIS. Hal ini dapat diantisipasi dengan menambah penangkal petir jenis aktif diatas gedung K FIS dengan radius minimal 107,47m. Tentunya dengan catatan melakukan evaluasi secara berkala, terlebih apabila terdapat pembangunan pada gedung yang berada pada radius perlindungan sistem penangkal petir tambahan.
