Abstract

Insulation materials that commonly used in air insulation, which, is operated at high voltage, are the porcelain, glass, and polymer materials. One of the insulating polymer materials that are used is epoxy resin because it has several advantages compared to that. However, this insulation material has a degradation of the surface due to environmental and cause insulation coated with dirt and chemicals in the long time.  This research was conducted on resin epoxy by comparison of MPDA, DGEBA, and filler (stone and silane) with a percentage value of 10%; 20%; 30%; 40% and 50%, sample size 120 x 50mm. Poly Ethylene is mixed as a compatibilzer of composite materials.Research was done in laboratory according to standard IEC 587: 1984. In this study, the effect of variation in stoichiometry to the hydrophobic contact angle value, leakage current waveforms, and surface degradation caused by erosion and tracking processes and tracking time were analyzed. From the results of the research, it was obtained that the epoxy resin that was used in this research are categorized as partially wetted. The increase concentration of silane and silica stone as filler caused the increase in contact angle which meant the increase in surface insulation resistance, so that leakage currents flew on the surface not easily and slow down the aging or the degradation decreasing on the surface of insulating material. The concentration value of comapatibilizer material that had the optimal performance was 4%.

Abstract

Rancang bangun robot pemadam api yang juga dapat mengikuti jejak menggunakan micro chip ATMega8535, dengan spesifikasi robot menggunakan foto dioda delapan buah sebagai sensorpelacak jejak sehingga robot lebih baik untuk kemungkinan keluar dari garis yang telah ditentukan, sensor jarak sebagai alat navigasi robot agar tidak menabrak, sensor api untukmendeksi api yang memungkinkan sensor ini bisa diganti-ganti sesuai dengan kebutuhan bisa dengan UVtron, LM35, LDR, atau foto dioda. Sensor mendeteksi adanya sumber api danmengaktifkan alat pemadam, penulis memasang fan sebagai pemadam apinya.Dilengkapi dengan LCD untuk memonitor progress kerja robot yang sekaligus untuk mengubah program robot secara langsung dengan bantuan empat tombol yang difungsikan sebagai menuatau cancel, ok atau start, up dan down. Program yang dapat dirubah melalui robot adalah kecepatan, pengambilan data sensor terhadap dasar putih sebagai kalibrasi, mencoba fungsi kerja robot dengan demo (maju, mundur, belok kanan, belok kiri). Juga dapat merubah program robot sesuai dengan program pilihan yang sebelumnya telah dimasukkan dalam menu utama robot tanpa menggunakan PC..Kata Kunci: robot, pemadam api, pelacak jejak, ATMega8535
