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.

In theory of language and automata explain about abstract machine which in there is finite state automata which can be implemented into vending machine. Vending machine for a city like Jakarta is not a difficult subject to find it. Operational way is already widely known procedures, but about how it works in the machine, still not many know it, through this simulation is expected the user also better understand it.Abstrak-Pada teori bahasa dan automata menjelaskan tentang mesin-mesin abstrak yang mana didalamnya terdapat finite state automata yang bisa diimplementasikan kedalam vending machine. Vending machine untuk kota seperti Jakarta sudah bukan perihal sulit untuk menemukannya. Cara kerja secara operasional sudah banyak diketahui prosedurnya, namun perihal bagaimana cara kerjanya didalam mesin tersebut, masih belum banyak yang mengetahuinya, melalui simulasi ini diharapkan pengguna juga lebih paham akan hal itu. Kata Kunci : Vending Machine, Simulasi, Finite State, Bahasa dan Automata.

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

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.

ABSTRAKEdukasi tuntunan shalat maghrib dengan mengedepankan multimedia termasuk gambar dan suara dapat mempengaruhi minat belajar anak-anak sehingga lebih mudah memahami gerakan dan bacaan shalat maghrib. Teknologi Berbasis Android Mixed Reality merupakan gabungan dari Augmented Reality dan Virtual Reality menjadi salah satu solusi yang mampu memenuhi kebutuhan multimedia tersebut karena terdapat unsur gambar, suara, serta objek 3 dimensi yang terlihat semi-nyata sehingga menambah daya tarik serta pengalaman menyenangkan bagi pengguna. Penggunaan aplikasi mixed reality membutuhkan bantuan perangkat keras VR Box agar mendapatkan pengalaman realitas yang maksimal. Perancangan aplikasi Mixed Reality menggunakan analisis algoritma Fast Corner Detection, algoritma ini penulis gunakan karena mampu mengidentifikasi sudut citra secara akurat, dan algoritma Lucas Kanade karena dapat mengidentifikasi transformasi citra secara efektif. Dengan adanya teknologi mixed reality ini pengguna bisa mengenal gerakan dasar serta bacaan shalat maghrib dari mulai niat hingga salam. Pengujian aplikasi menggunakan tiga device smartphone android, pada rentang sudut 20 o -90 o objek 3 dimensi muncul karena marker dapat terdeteksi oleh kamera. Rata-rata objek 3 dimensi ditampilkan dengan waktu 1 detik jika cahaya pada marker terang.

Augmented Reality is a technology on 2-dimensional and 3-dimensional virtual objects that are combined into the real environment that is around us. With the ability of Augmented Reality that is able to change the atmosphere of children’s learning that can be used as a medium of learning in the introduction of mammals for kindergarten children. This AR can provide interesting facilities such as displaying 3-dimensional objects of these mammals along with animal sounds and animations using Smartphones, so that children can interact and be more creative in recognizing these mammals, because children experience their golden age at the age of 4 to 7 years which is a time when children begin to receive stimuli, so that children will be faster to receive and catch on learning from the introduction of these mammals by using Augmented Reality Technology. The results of testing on the Vuforia plugin and making the AR application on Unity can provide a good information result, where the use of AR can bring up mammalian objects by pointing the Smartphone at the marker, so that all mammals can be recognized properly. This shows that children’s interest around 85% in terms of UI/UX appearance, and 70% of children have no problems in running the Mammal Animal AR application
