Abstract

Kartu identitas atau identification card menjadi pendukung utama dalam gate system. Penelitian ini bertujuan untuk menerapkan smart card pada smart gate di kalangan civitas akademika sebagai pengguna. Sistem ini menggunakan Near Field Communication (NFC) smart card jenis MIFARE sebagai identitas untuk identifikasi dan otentikasi. Proses baca / tulis dikonfigurasi dimana blok data dapat dibaca dengan menggunakan software yang telah dirancang dengan menggunakan aplikasi Visual Basic 2010. Proses penulisan data pada NFC tag melalui komunikasi serial dimana data informasi digabungkan menjadi 1 line informasi yang telah melalui tahapan enkripsi kemudian dialokasikan dalam bentuk array kedalam blok data yang telah ditentukan dalam penelitian ini yakni blok data 9,10,11 dan 13 dengan total data 64 Byte. Keamanan informasi pada NFC tag dilakukan dengan enkripsi metode Caesar Chiper dan rotate letter. Waktu yang dibutuhkan dalam melakukan pembacaan informasi dari database ke NFC tag tanpa adanya penghalang yakni waktu tercepat 1.49 detik dan terlama 2.26 detik dengan rata-rata waktu proses 1.84 detik, sedangkan untuk pengujian dengan menggunakan penghalang diperoleh waktu tercepat 1.53 detik dan waktu terlama 2.21 detik dengan rata-rata waktu proses 1.83 detik. Hal ini menandakan waktu yang digunakan dalam proses penulisan informasi efisien dan tidak terpengaruh oleh adanya penghalang. Hasil penelitian menunjukkan bahwa dengan adanya proses enkripsi informasi pada NFC tag hanya dapat dibaca melalui aplikasi Visual Basic yang telah dirancang dan dilengkapi dengan sistem enkripsi dan dekripsi.

Abstract

One of the main components of wind power plants that can be developed is the Permanent Magnet Synchronous Generator (PMSG). In this research, PMSG design will be carried out using Finite element method software with Geometry Variations of Permanent Magnet Synchronous Generator with a combination of 12 8-pole slots which will then be modeled on Finite element method software. In one variation of this generator geometry has been successfully created with good efficiency. This model will argue for the specifications of variations 1, 2 and 3 and are analyzed by comparison test scenarios and loading with load R. The generator with a no-load test simulation produces between variations in variation 1 of 10.93 volts, variation 2 of 12.67 volts, variation 3 of 13.77 volts. When testing load with load resulted in an efficiency of variation 1 of 20.5%, variation 2 of 19.6%, and variation 3 of 33.4%.

Abstract

One of the renewable energy that is growing rapidly in the world today is wind energy. Wind energy is a very flexible energy. The wind potential of the Torea Fakfak Airport area, West Papua is quite strong considering that planes often fail to take off due to strong winds, wind measurement data collection is located in a coastal area, so this study aims to evaluate the potential of wind energy in the Torea Fakfak area as an alternative renewable energy source. This study involves analyzing wind speed data for one month using an anemometer measuring device installed in a strategic location, this measurement was only carried out at a height of 2 meters. The results show that the average wind speed in the area reaches 2.6 m/s. The electrical energy power obtained in these conditions is 79.77517 watts or in 24 hours the power generated is around 1,914.60 watts. The power generated is not large but the energy can be optimized for the needs of public facilities such as street lights and also the needs of equipment such as TVs, laptops, small refrigerators and others Keywords: Wind Potential, Electrical Energy, Wind Speed, Sea Breeze.
