The selection of quality gemstones requires a special ability to select and assess the quality of gemstones to be traded. The diversity of types of gemstones and consumers becomes an obstacle in itself when the knowledge and ability of individuals to analyze the quality of gemstones is minimal. The decision-making method used is Fuzzy Analytical Hierarchy Process (F-AHP) method which is widely used in various sectors. F-AHP is easy to adapt to many decision issues; the research proposes a decision-making system using the F-AHP algorithm to analyze the quality of gemstones. The results obtained with the use of F-AHP model in the selection of quality gemstones show the highest quality of gemstones of all stones compared, Rubi 1, with a weight value of 0.152942.
Everyday busy making plant owners leave their plants, this causes their plants to wither or die, in this study aims to build a smart watering system for plants using the Blynk smartphone application that has been integrated with the Arduino Uno R3 mikrocontroller because it is connected through software Arduino IDE program input to run as desired an which is equipped with a Relay 5V tool deliver voltage, and Aquarium Pumps so that water can flow to plants. Then for Thingspeak it self, it useful to display the moisture value in the soil that will be displayed on the web that has been connected with the Arduino Uno R3. Soil Moisture Sensor to let you know if the soil content is below 400 then the soil is most moist and if the soil above 900 the soil status dry, trough this Smartphone can water the plants with time or use the on / off button that is already available in the Blynk Smartphone app view
Museum Fatahillah dan Museum Wayang merupakan Museum Sejarah yang berada dikawasan kota tua Jakarta. Namun masalah yang terjadi saat ini adalah kurangnya media untuk mengenalkan kembali sejarah dan pengetahuan berdirinya Museum Fatahillah dan Museum Wayang Maka pada penelitian ini, dirancanglah sebuah aplikasi Augmented Reality berbasis Android sebagai media informasi menggunakan metode markerless 3D Object Tracking. Aplikasi Augmented Reality museum ini menyediakan ftur- fitur yang dapat menarik pengguna dalam mencari informasi. Hasil yang didapatkan pada penelitian ini yaitu berupa sebuah 3D object dengan tambahan informasi berupa teks dan video Animasi, yang bertujuan sebagai salah satu pembelajaran alternativ berbasis teknologi.
Education in children is not only learning from books, with the development of educational technology it can be done using technological equipment such as computers, smartphones, or gadgets. The use of the Augmented reality application can be used as an example in learning in early childhood by introducing land animals in 3D. This study aims to provide education, especially to children, about the introduction of land animals by utilizing augmented reality technology. This research uses a marker-based tracking method and a fast corner detection algorithm. The results of the study resulted in an application that contained the introduction of land animals consisting of dogs, horses, kangaroos, cats, wolves, elephants, deer, camels, giraffes, and cows. Brief information about each animal, designed to be as attractive as possible for children. Applications can run on the Android operating system.Keywords:Augmented reality, 3D Objects, Marker Based, Fast corner detection.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
