Abstract

Principal Component Analysis (PCA) adalah metode yang sangat populer untuk pengenalan wajah. PCA merupakan salah satu analisis peubah ganda yang bertujuan untuk mereduksi dimensi citra tanpa harus kehilangan informasi yang berarti. Prinsip dasar dari reduksi dimensi ruang eigen adalah mentransformasikan titik-titik pada ruang asal ke ruang baru yang dibentuk oleh sumbu-sumbu vektor eigen. PCA1D maupun PCA2D menggunakan vektor eigen (ciri) dari matriks koragam sumbu-sumbu pembangkit ruang asal. PCA2D merupakan metode varian dari PCA. PCA1D berbasis ruang vektor sedangkan PCA2D berbasis matriks. Penelitian ini akan memperbandingkan kedua metode tersebut dan menganalisa tingkat keberhasilan dan faktor-faktor penyebabnya.

Abstract

Mercu Buana University is a private university which consists of seven faculties. At the Faculty of Design and Creative Arts, Faculty of Communication Sciences and Faculty of Engineering, additional requirements are required for new student candidates, i.e. a color blindness free certificate. Color blindness is a vision disorder caused by the inability of the eye cone cells to perceive a certain spectrum of colors. There are many ways to test someone's color blindness, one of which is by using the Ishihara method. To obtain a color blindness free certificate, prospective students must visit a clinic or hospital, carry out the applicable color blind test procedure, then bring the results to campus. Based on these problems, the research was conducted with the aim of making a color blind test application that can issue a recommendation letter based on the test results of prospective new students. The system development method uses System Development Life Cycle. The results of the study were an android-based color blind test application that was able to detect color blindness using the Ishihara method and issued a recommendation letter based on the test results of prospective new students in the on-time application.

Abstract

The growth of online s in Indonesia is fast and is in great demand by many people from children to adults. Online s are very popular because of the PVP system (player vs. player) that let players can fight each other online. PVP s make their customers more competitive and makes players to play more intensively in order to get a higher level or ranking than other player. Playing intensively has an effect on the aggressiveness of players so that behavior makes it less respectful to other player such as issuing invective words to other players. Online s also have systems that are not suitable for kids such as microtransaction and gacha systems. this resulted in kids making transactions without the knowledge of their parents even spending up to tens millions rupiah. not to mention the gacha system, which is the purchase of items at. therefore the author wants to build a application with cooperative principles as a that deserves to be played by kids. In making this Astan Eva application using the MDLC method (Multimedia Development Life Cycle). MDLC has stages by Concept, Design, Material Collecting, Assembly, Testing, and Distribution.

Abstract

Unit Pengelola Terminal (UPT) Rawamangun yang berada di Jl. Perserikatan, Rawamangun, Pulogadung, Jakarta Timur, merupakan pangkalan dari berbagai jenis kendaraan umum. Dari mulai angkutan kota hingga bus antarkota. Banyak fasilitas umum yang disediakan untuk pengunjung dan calon penumpang bus. Diantaranya seperti ruang tunggu, arena makan, serta ruang menyusui. Dengan demikan diperlukan perawatan-perawan terhadap fasilitas umum yang ada agar tetap memiliki nilai guna. Namun untuk memperhatikan semua fasilitas umum yang ada akan memakan waktu jika hanya suatu organisasi saja yang melakukannya. Maka dari itu diperlukan suatu sistem informasi dimana bisa menjadi tempat pelaporan dari kerusakan fasilitas umum yang ada di terminal. Sehingga laporan tersebut bisa sampai pada pihak yang berwenang untuk langsung diperbaiki. Website ini  juga diharapkan lebih efisien karena bermanfaat untuk memudahkan masyarakat dalam berpartisipasi dengan melaporkan kerusakan yang ia temui, dengan adanya fitur-fitur serta konten yang membantu berbagi informasi antara masyarakat dengan pihak pengelola terminal.

Abstract

At present the company is always trying to replace the work done by humans, replaced by machines in order to improve the efficiency and quality of production. In other words, many companies automate their production. For example, production processes that were initially carried out manually as in the process of sorting their products. In the industry this process is done manually with human effort and requires a large amount of labor and makes the production process longer. To overcome this problem, companies that want more effective and efficient production processes to change production patterns by applying automation in their production systems. This is realized by the construction of a packing system for goods, where the system usually consists of goods distribution in the form of a mechanical conveyor system and packaging of goods. As in the case of items based on the color sorting system, you will need a tool that can automatically sort this product. This system consists of object sensors, color sensors, conveyor belts, and means of dividing goods. Mechanical systems are built using acrylic, plastic and PVC. The control system in this simulation uses the AT89s51 IC microcontroller.Keyword : Augmented Reality, Satya Negara Indonesia University, Virtual Reality, 3D

Abstract

In the digital image processing, many methods have been developed, the purpose of developing these methods is how computers can detect and recognize objects in an image with a precisely and process them in a relatively short time. Wheels are components that are always present in every vehicle, whether the vehicle is a bus, car or truck, it must have wheels with the same shape. If a wheel can be detected and recognized then the vehicle recognition and classification can be determined. This research focuses on capturing circle images, detecting wheel circles by applying Circle Hough Transformation (CHT). This transformation is able to recognize the object based on its boundaries and is resistant to noise. After obtaining the image of the circle, the next step is to classify it into Wheels and Non Wheels using the Support Vector Machine (SVM) method. The development of the wheel circle detection model on the side view image of this vehicle can be used as one of the first steps in research on wheel-based automatic vehicle recognition and classification systems.
