Abstract

Di dalam kehidupan sehari-hari, penentuan klasifikasi ukuran pakaian biasanya dilakukan dengan mencoba-coba pakaian terlebih dahulu sehingga membutuhkan waktu yang lebih lama. Dalam makalah ini, kita ingin membangun sistem untuk mengidentifikasi ukuran tubuh manusia dengan kamera. Selanjutnya dilakukan klasifikasi ukuran pakaian secara otomatis berdasarkan ukuran tubuh tersebut. Pendekatan yang diajukan untuk memecahkan hal ini adalah dengan metode body measurement dan Fuzzy Logic dengan menggunakan Kinect sebagai sensor. Metode body measurement digunakan untuk mengukur ukuran anggota tubuh manusia berdasarkan citra yang berasal dari sensor Kinect. Fuzzy Logic digunakan untuk menentukan klasifikasi ukuran pakaian berdasarkan hasil pengukuran yang diperoleh. Sistem pengukuran dak klasifikasi ini dapat mempermudah penentuan klasifikasi ukuran pakaian yang pas. Hasil dari penelitian ini menunjukkan bahwa sistem klasifikasi yang dibangun dapat menentukan ukuran pakaian dengan False Match Rate (FMR) sekitar 2.69%.

Abstract

Penelitian ini menjelaskan mengenai model komplementer SEIQRS-V (Susceptible - Exposed - Infectious - Quarantined - Recovered - Vaccinated) yang digunakan untuk menganalisis kondisi jaringan di setiap waktu. Dengan menerjemahkan model komplementer menjadi sistem persamaan differensial, dapat diperoleh kondisi jaringan di setiap waktu dengan menggunakan metode numerik Runge-Kutta Fehlberg dan metode numerik Adam Bashforth Orde 3 yang diimplementasikan ke dalam aplikasi untuk analisis kondisi dan kestabilan jaringan komputer. Aplikasi analisis ini dibuat untuk menampilkan jumlah komputer pada setiap kelompok dalam bentuk tabel, grafik dua dimensi, maupun grafik tiga dimensi. Dengan menggunakan metode numerik yang diimplementasikan pada aplikasi ini, diharapkan pengguna dapat mensimulasikan kondisi jaringan komputer yang ada.

Abstract

Information Technology does help people to get information promptly anytime and anywhere. Unfortunately, the information gathered from the Internet does not always come out positive. Some information can be destructive, such as porn images. To mitigate this problem, the study aims to create a desktop application that could detect parts of human body which can be expanded in the future to become an image filter application for pornography. The detection methodology in this study is Viola-Jones method which provides a complete framework for extracting and recognizing image features. A combination of Viola-Jones method with Haar-like features, integral image, boosting algorithm, and cascade classifier provide a robust detector for the application. First, several parts of the human body are chosen to be detected as the data training using the Viola-Jones method. Then, another set of images (similar body parts but different images) are run through the application to be recognized. The result shows 86.25% of successful detection. The failures are identified and show that the inputted data are completely different with the data training.

Abstract

Nowadays, one of industrial main problems is the flexibility of machines to be customized since they are designed based on certain standard. This research develops software for CNC (Computer Numerically Controlled) machine in order to execute the Newton Interpolation using Python. The platform used in the CNC machine is EMC (Enhanced Machine Control) and GUI (Graphical User Interface) AXIS on the operating system Linux Ubuntu. The Newton interpolation is used to create a curve based on several point determined by user. By converting this curve into G-Code, which could be read by CNC machine, the machine can move according to curve designed by user. This research is an initial study to customize the CNC machine and will continue to fulfill the user needs. This research obtained a program that is able to run well up to 4 input pairs. The higher number inputs will cause the oscillation in the interpolation curve.

Abstract

This research focused on the social communication process for increasing tolerance and harmonization of inter-religious communities in Indonesia. This research method used the case study design. Research data of this case study were collected through observations and in-depth interviews. The results indicate that the process of social communication between religions takes place dynamically in the community. It involves mutual interactions and respect for each other according to social norms and values adopted by the local community. By interacting and respecting each other, the social life of the community can be maintained to be harmonious, safe, comfortable, full of tolerance and harmony, and coexist in religious, cultural, ethnic, racial, and ethnic diversity. Based on research findings, all can be done through the social communication process for increasing tolerance and harmonization of social life among religious communities in Indonesia that the process of social communication is directly referred to as traditional and conventional communication.
