Abstract

Pintu air pada bendungan dapat digunakan untuk mengendalikan banjir. Banyak dijumpai pintu air pada bendungan di berbagai tempat masih dikendalikan secara manual. Namun saat ini cuaca yang tidak menentu, kadang panas kadang hujan lebat sehingga dapat menyebabkan  debit air pada bedungan sungai meningkat. Jika hal ini terjadi maka terpaksa pintu air harus dibuka dengan terburu-buru ketika volume air di bendungan tiba-tiba meluap sehingga harus dialirkan ke hilir secara mendadak yang bisa mengakibatkan banjir. Banyak kerugian yang di timbulkan akibat kejadian banjir tersebut, diantaranya yaitu kerugian material dan bahkan kemungkinan jatuhnya korban jiwa. Kejadian tersebut diharapkan bisa dihindari dengan menerapkan kendali pintu air otomatis berdasarkan debit air yang terdeteksi oleh sensor ultrasonik dengan memanfaatkan Nuvoton NUC140VE3CN dan dapat menampilkan berbagai keadaan  level ketinggian air dan  tanda peringatan .

Abstract

Demensia merupakan gangguan neurodegenerative yang terkait dengan penuan yang menyebabkan penurunan kemampuan kognitif manusia karena degenerasi struktur otak. Banyak cara untuk mendeteksi penderita demensia namun masih belum diketahui penyebabnya. Oleh karena itu data pasien yang berkaitan dengan data demografis ditambahkan selain data klinis. Sehingga terdapat banyak data yang diharapkan kemudian dapat digunakan untuk mengetahui penyebab penyakit demensia. Dengan banyak data yang ada akan lebih mudah pengelolaanya agar dapat diperoleh menjadi pengetahuan, menggunakan data mining. Pengelompokkan banyak data menggunakan K-Means Clustering. Banyak aplikasi computer untuk menerapkan metode data mining diantaranya RapidMiner dan Weka. 2 aplikasi ini akan dibandingkan untuk penerapan pengelompokan penderita dementia menggunakan K-Means Clustering. Hasil yang di dapat adalah memulai aplikasi Weka lebih mudah namun untuk visualisasi akan lebih baik menggunakan RapidMiner.

Abstract

Series of "Design of Microcontroller Based Digital Queue System AT89S51 "function to help create an atmosphere that is safe, comfortable and compliant at the time of the queue for a particular transaction. This tool is designed with the input of a switch, data processing using AT89S51 Microcontroller IC, and output display  and buzzer as an indicator seven-segment detecting the number of queues. This tool works by detecting a pressure switch input, then the microcontroller will process input into the input data which would then be used to perform the counting process and the results will be displayed on the seven-segment indicator with buzzer that sounds. Views on the seven segments of this function is to provide information to visitors (queue) that the numbers that appear in the seven-segment display shows the queue number that will make transactions.

Abstract

Along with the development of science and technology, has had a positive impact in the industrial world, especially in the utilization of the temperature measurement system that uses the principle of data acquisition. With the computer, then use the computer to control a temperature measurement system is now a practical and common. In industries that require extremely high temperatures on the production process, the temperature must be kept at certain temperatures. Therefore, this paper aims to facilitate the temperature control in an industry that requires high temperatures in its operations.At this writing, the series of temperature control systems can work well, although there are deviations from the value of the actual value. This is supported by the performance of each component in the system. If each component in the system can work in accordance with their respective functions, the system will have the reliability (reliability) in order to work properly.For ease in the observation, the authors use a table test. Table test was used to ascertain level deviations from the data obtained with actual data. Table testing can also be used as a way to process the data using least squares method, so it is easy in analyzing.At this writing, the authors analyze this control system with the way this system divides into several blocks of the circuit. From each of these circuit blocks will be determined the value of its output, so it can ascertain performance in each block. Obtaining the value of output is shown in the table experiments and processed using the least square method to determine the level of its deviation. Of this paper can then be developed into a more useful applications, such as incubators. Writing is very useful especially for students who want to deepen their computer system about temperature control system. And generally to the reader, either the hobbyist or a company or industry that uses a system of temperature control in process operations.

Abstract

Wireless Network or Wireless LAN is the networking technology that is not using thecable that can be found inside a computer network at the moment. These technologiesuse radio waves to make the interaction or communication between the computerunit. Wireless LAN is basically a radio device capable of connecting datacommunication between computers or a computer to a Local Area Network (LAN) orvice versa. The purpose of this paper is to use the wireless network can be built aLAN network without using cables that give the computer accessing the network.Access Point used as regulator of transmission between computers in a wirelessnetwork. Access Point acts like a HUB in a network that uses cables.
