Abstract

Wireless Local Area Network (WLAN) adalah salah satu solusi sangat efisien tetapi masih memiliki sedikit kelemahan, antara lain adalah keterbatasan area yang dapat di cover oleh access point. Antena payungbolic salah satu antena yang dapat digunakan untuk menangkap sinyal WLAN 2,4 GHz pada sisi penerima. Antena ini termasuk dalam kategori antena parabola yang terdiri dari reflektor, director dan feeder (fokus). Reflektor menggunakan payung bekas dan tangkai payung yang digunakan untuk penempatan feeder (fokus) dan director. Fokus menggunakan pipa paralon yang diberi foil (lapisan tembaga). Pada bagian fokus dipasang USB adapter yang berfungsi untuk menampung semua sinyal yang dipantulkan oleh reflektor kemudian dikirimkan ke komputer atau laptop melalui kabel penghubung. Antena ini bisa dibuat sendiri dengan biaya yang tidak terlalu mahal dibandingkan antena grid yang ada di pasaran. Untuk melihat kelayakan suatu alat maka perlu dilakukan perbandingan dengan peralatan yang ada dan memiliki data sheet standar. Maka dilakukan penelitian Analisa Receive Signal Strength Indicator (RSSI) antena eksternal payung bolic dengan Antena directional parabola. Metode penelitian yang digunakan adalah true eksperimen, yaitu melakukan percobaan pengukuran signal strength terhadap kedua antena pada lokasi yang sama, ketinggian, dan panjang kabel sama serta dipilih lokasi yang dapat menerapkan komunikasi Line Of Sight. Dari hasil signal strength terlihat jelas perbedaan antena payungbolic dengan antena directional parabola. Untuk melihat apakah perbedaan gain antena signifikan dianalisis dengan uji t. Dari uji t tersebut ternyata t hitung lebih kecil dari t tabel, sehingga didapat kesimpulan bahwa tidak ada perbedaan signal strength yang signifikan antara antena payungbolic dan directional parabola pada jarak ≤ 300 meter.

Abstract

The wokbolic antenna is used to capture the 2.4 GHz wireless LAN signal. The reflector is made of a frying pan. Focus on using a foil-lined paralon pipe. At the focus is given a USB adapter to capture the signal reflected by the reflector. To see the feasibility of a tool needs to be compared with equipment that has a standard data sheet. So a research was conducted by comparing the capture power of the wokbolic antenna with a directional parabolic antenna. The research method used is a real experimental method, namely an experimental signal strength measurement of both antennas at the same location, altitude under LOS conditions. From the results of experiments conducted at five distances: at a radius of 50 meters, 73 meters, 120 meters, 150 meters, and 290 meters. The farther the capture distance, the smaller the received signal, this happens to both antennas. After the data is obtained in the form of signal strength, then the antenna gain is calculated. The results of the antenna gain calculation show the difference between the gain of the wokbolic antenna and the directional satellite dish. To see if the difference in antenna gain is significant, it is analyzed by t-test. From the t test, it turns out that t count is greater than t table, it can be concluded that the difference in antenna gain is not significant.

Abstract

Siswa merupakan salah satu elemen kunci dalam sistem pendidikan, maka dari itu butuh petunjuk untuk dapat dinilai dengan baik. Peraturan disiplin siswa diharapkan dapat menjadi pedoman pelaksanaan seluruh kegiatan siswa sehari-hari baik di dalam maupun di luar sekolah. Penentuan siswa teladan diukur berdasarkan kriteria yang harus dimiliki oleh setiap siswa sesuai peraturan displin siswa yang diterapkan di sekolah. Di SMK Negeri 1 Lintau Buo penentuan siswa teladan masih dilakukan secara manual dan hasilnya belum objektif. Sehingga untuk hasil yang diperoleh terkadang penuh pro dan kontra. Data Mining digunakan untuk mempelajari data yang tersedia di bidang pendidikan dan menghasilkan pengetahuan tersembunyi. Metode klasifikasi seperti Algoritma C 4.5, diterapkan pada data pendidikan dengan memanfaatkan pengetahuan tersembunyi untuk memprediksi seluruh aspek kinerja siswa. Prediksi ini juga membantu dalam penentuan kriteria siswa teladan. Hasil prediksi tersebut juga untuk perbaikan kinerja siswa secara keseluruhan terutama dalam proses pembelajaran. Penelitian dilakukan terhadap siswa SMK Negeri 1 Lintau Buo sebanyak 75 data siswa yang memiliki peringkat kelas 1, 2 dan 3 disetiap kelas. Hasil yang diperoleh dari proses klasifikasi ini adalah kriteria terbaik untuk penentuan siswa teladan dengan node yang diperoleh yaitu, Prestasi Non Akademis, Kehadiran serta Kegiatan sosial. Keakuratan proses klasifikasi pada Data Training diperoleh sebesar 1.00, pada Data Testing1 diperoleh sebesar 0.90 serta pada Data Testing2 diperoleh sebesar 1.00.

Abstract

The purpose of this study was to determine the correlation between e-literacy and the behavior of searching for scientific information on the internet by students of the Payakumbuh High School of Technology. This research uses quantitative research methods. The variables of this study are: the independent variable is digital literacy (X) and the dependent variable is information retrieval behavior (Y) using the Simple Random Sampling Technique with a total of 221 students of the Payakumbuh High School of Technology. The results of the descriptive analysis test using the Mean and Grand Mean formulas obtained the results of digital literacy categorized as good with an average value of 3.23. Meanwhile, information seeking behavior is categorized as good with an average value of 3.21. Based on the product moment correlation test, the correlation coefficient between digital literacy variables (X) and information retrieval behavior (Y) was obtained at 0.824 at the coefficient interval between 0.80-1,000 indicating a very strong relationship, with a positive direction because the value of r indicates a positive number. . Furthermore, based on the results of a simple regression test for the X and Y variables, the equation Y = 18.010 + 1.438X and RSquare of 0.68 means that the relationship between digital literacy and information retrieval behavior is 68%. While other factors outside this study amounted to 32%. So it can be concluded that there is a correlation of e-literacy on the behavior of searching for scientific information on the internet by students of the Payakumbuh High School of Technology.

Abstract

Many libraries have developed services in information systems to facilitate library management. The purpose of this information system is to optimize the performance of library services. In Padang Ganting 1 Public Middle School, providing services for searching, borrowing, and returning books to the library is still manual, so it is necessary to develop an information system in the form of a library automation system. The information system is designed using a programming language, which is software that makes it easy to manage procedures or mechanisms in the library, such as borrowing, searching, returning, and developing, with an automated system. A library information system is available to assist in managing the library electronically so that it is easier for the library to record every data transaction contained in the library.

Abstract

Alumni are students who have completed the level of education with all the rules at a learning institution. So far, the alumni data collection at SMK Negeri 1 Batusangkar is still using the manual system. Therefore, a Web-Based Alumni Data Collection Application was built using the PHP programming language and database processing using Mysql and using the CodeIgniter framework. The purpose of this study is to analyze the performance and user satisfaction of this application. The method used in this study is a quantitative method using GTMetrix as software testing to analyze application performance and the PIECES evaluation model to analyze user satisfaction. Based on the measurement of application performance with GTMetrix, grade A is obtained, which means that the performance of the web application is good. Meanwhile, from the calculation of the level of user satisfaction, it is stated that of the six variables owned by the PIECES method, an average value of 4.26 is obtained which is in the range of 4.2 - 5.0 which means that the level of user satisfaction with this application is in the "very satisfied" category.
