PENGEMBANGAN PERANGKAT OTOMASI MITER GATE PADA SALURAN IRIGASI DENGAN TEKNOLOGI PUSH NOTIFICATIONS

Pintu air Leonardo da Vinci Miter Gate memiliki desain yang dianggap efektif menahan air. Adanya perkembangan teknologi yang sangat pesat menjadikan push technology mudah diterapkan dalam sistem yang terintegrasi dengan internet. Penelitian ini bertujuan untuk mengembangkan perangkat otomasi pintu air irigasi menggunakan model Leonardo da Vinci Miter Gate dan pengiriman informasi melalui push technology. Penelitian ini dilakukan melalui lima tahapan yaitu: studi literatur, rancangan fungsional, rancangan struktural, analisis teknik, dan pengujian sistem otomasi dengan menggunakan Arduino UNO, Sensor ultrasonic HC-SR04, Motor Servo dan Router sebagai perangkat utama dalam penelitian ini. Penelitian ini menggunakan metode rekayasa dan menghasilkan purwarupa saluran irigasi dan pintu air model Leonardo da Vinci Miter Gate dan integrasi dengan perangkat otomasi berhasil menghasilkan informasi yang dapat dibaca pengguna melalui layer LCD ataupun melalui smartphone. Temuan dari hasil pengujian adalah terjadinya kebocoran pada pintu sebesar 5-8% dari debit inlet. Pada rancangan fungsional sensor, aktuator dan pemantauan data ketinggian muka air berjalan sesuai dengan skrip yang ditulis dan menghasilkan rata-rata penerimaan notifikasi selama 3 detik setelah pengiriman informasi. Kata Kunci: Arduino UNO. Leonardo Da Vinci, miter gate, push notification

Trend Analysis of Technologies Supporting the Availability of Online Content: From Keyword-Based Search to the Semantic Web

The era of Web 1.0 implied the connection of web-based documents via links, which enabled search engines to scan for information and guarantee the search and availability of webpages. Web 2.0 represented the next evolutionary stage. Known as the collaborative web, the emphasis in this case was on the establishment of services and content by the community. Search options were complemented with labelling and frequently undesirable clickstream analysis coupled with push technology-supported information provision. The semantic web is a revolutionary development, which, in addition to processing information by humans, assures the readability of datasets by machines and facilitates communication between devices. In order to promote data and information processing by machines, the semantic web relies on a special ontology allocating the respective meaning to the given data along with relying on the global indexing and naming schemes of the web. Several ontologies emerged with differing basic guidelines while displaying compatibility to the RDF standard ranging from the more semantic description of bibliographical data in libraries to the description of information gained from social networks and human conversations. While Web 3.0 is often used interchangeably with the semantic web, the former one with its intelligent server function exceeds the semantic web. We have to ask ourselves, however, whether we can rely on the accuracy of the obtained data, and we must explore what progress have libraries – expected to increase reliability – made regarding the implementation of semantic data storage.
