Abstract

Abstract - Hand gesture interaction is the most relevant approach when interacting in augmented reality. This approach is natural, simple, inexpensive and accurate. The research has three goals that are: to apply the concept of epipolar geometry for geometric of stereo vision, to calculate accuracy of the projective reconstruction method and to make a model for hand gesture interaction in augmented reality. Hand gesture interaction in augmented reality is affected by the accuracy of feature point detection. In this experiment, the percentage of sum of difference from feature point detection is about 3% while the percentage of sum of difference from feature point reconstruction is about 93%. Based on this experiment, the most accurate interaction is obtained from the combination of the sub-pixel feature point detection and the optimal triangulation algorithm. The interaction can be run in real-time by 2.6 fps.

Abstract

The understanding of the Indonesian people about the importance of abundant raw materials is very lacking, this is evidenced by the many understandings that mocaf (cassava flour) is a raw material that cannot be processed properly and attractively so that it does not become a trend. Indonesia is one of the countries producing cassava although cassava is not a staple food. People need to know and understand the extent to which cassava can be processed into cassava flour, and cassava flour into bread. This study designs and builds applications that are educational to provide understanding to the community, especially for school-age children, considering that the main education is when compulsory children are elementary, middle and high school. In this study the Game Development Life Cyle (GDLC) method is used which consists of the stages of initiation, pre production, production, testing. In this study playtesting evaluation was carried out for 20 respondents with a play time of 10-15 minutes, covering aspects of concentration in addition to functional testing. Concentration aspects are valued at 4,15.

Abstract

Object detection based on digital image processing on vehicles is very important for establishing monitoring system or as alternative method to collect statistic data to make efficient traffic engineering decision. A vehicle counter program based on traffic video feed for specific type of vehicle using Haar Cascade Classifier was made as the output of this research. Firstly, Haar-like feature was used to present visual shape of vehicle, and AdaBoost machine learning algorithm was also employed to make a strong classifier by combining specific classifier into a cascade filter to quickly remove background regions of an image. At the testing section, the output was tested over 8 realistic video data and achieved high accuracy. The result was set 1 as the biggest value for recall and precision, 0.986 as the average value for recall and 0.978 as the average value for precision.

Abstract

Malang Waste Bank, or commonly called Bank Sampah Malang (BSM), is a legal entity of incorporated cooperatives built by the Malang municipal government serving as a container of waste management, especially dry waste. During this time, the customer service process conducted in BSM has been not optimal, especially its online service. Some services have been accessible online through website but the information is limited only to the list of prices and types of waste received by BSM. While other necessary information needed by the customers such as balance checking, garbage collection schedule checking, and information about the types of saving managed by BSM has not been covered by the existing online system yet. This research has built an online customer service system based on mobile applications and SMS gateways for BSM. The purpose of the system is to facilitate the customers of BSM to obtain information about the garbage bank, especially for customers having high mobility. Interviews and observation are used as the method of the analysis of the system requirements. Meanwhile, the applications such as MySQL database, Web service, PHP CodeIgniter, SMS Gateway and Android as a language programming are used to develop the system. This system integrates android applications with web based applications by using web service. This system is made so that customers get better service. Evaluation results show the system that has been built has been successfully tested.

Abstract

Penelitian ini bertujuan untuk mengetahui lingkungan kerja pada industri kecil kerajinan Batik Sidomukti Kabupaten Magetan, untuk mengetahui kinerja karyawan pada industri kecil kerajinan batik Sidomukti Kabupaten Magetan. dan untuk mengetahui seberapa besar pengaruh antara lingkungan kerja terhadap kinerja karyawan pada industri kecil kerajinan Batik Sidomukti Desa Sidomukti Kecamatan Plaosan Kabupaten Magetan. Penentuan sampel di dalam penelitian ini menggunakan sampel bertujuan yaitu karyawan industri kecil kerajinan Batik Sidomukti yang berjumlah 35 karyawan. Pengumpulan data menggunakan metode kuesioner dan dokumentasi. Dalam menganalisis data pada penelitian menggunakan uji korelasi produk momen, uji F, dan uji t. Lingkungan kerja memiliki nilai rata-rata sebesar 47,63 dengan nilai maksimum 50, nilai minimum 40, standar deviasi 2,860, median 49,00, dan modus sebesar 5. Dari hasil deskripsi variabel lingkungan kerja diketahui bahwa responden cenderung setuju terhadap lingkungan kerja yang baik, karena lingkungan kerja yang baik dan kondusif dapat meningkatkan kinerja karyawannya dalam proses produksi yang telah dibebankan oleh perusahaan.  kinerja karyawan memiliki rata-rata sebesar 48,66, dengan nilai maksimum 50, nilai minimum 44, standar deviasi 1.804, median 49,00 dan modus sebesar 50.

Abstract

Pertumbuhan bisnis properti di Indonesia setiap tahun mengalami peningkatan, namun tidak banyak pihak pengembang properti di Indonesia yang memanfaatkan teknologi Augmented Reality (AR) sebagai media promosi untuk memasarkan produk, rata-rata masih menggunakan brosur. Penelitian tentang katalog penjualan rumah menggunakan AR juga bukan hal baru, ada beberapa penelitian sejenis yang sudah pernah dilakukan sebelumnya, namun dikonsentrasikan pada pendeteksian marker untuk menampilkan model 3D baik menggunakan marker khusus atau brosur yang dijadikan sebagai marker. Marker yang berhasil dideteksi menampilkan objek denah dan bentuk rumah 3D. Penelitian ini fokus pada pembuatan katalog penjualan rumah menggunakan teknologi AR dengan menambahkan  fitur yang belum ada pada penelitian sebelumnya. Beberapa fitur yang ditambahkan adalah mengubah warna cat dinding, pintu dan jendela pada model rumah 3D, sehingga pengguna dapat mengubah warna sesuai dengan warna yang disediakan. Katalog penjualan rumah menggunakan teknologi AR yang dikembangkan berjalan pada platform android mobile dan dibuat menggunakan aplikasi Unity. Metode yang digunakan pada penelitian ini adalah SDLC Waterfall. Hasil pengujian menunjukkan bahwa aplikasi dapat berjalan sesuai dengan yang direncanakan khususnya fitur-fitur yang ditambahkan seperti fitur untuk mengganti warna cat dinding, pintu dan jendela pada objek rumah 3D dapat dijalankan dengan baik.

Abstract

This research proposes the three dimensional (3D) interaction on the augmented reality (AR) environment based on interposition. Interposition is captured from the intersection of reconstruction points. That points should be increased to generate accurate interposition. The optimal triangulation is used to increase the performance for reconstructing 3D. This method is applied to Logitech camera (passive stereo) and Kinect camera (active stereo) to analyze the result of reconstruction. Based on the calibration testing, optimal triangulation gives a significant deference accuration on both of Logitech and Kinect cameras. On the passive stereo, accurate interaction is generated by combining subpixel detection and the optimal triangulation algorithm, while on the active stereo, the accuration of depth image can be improved by just applying the optimal triangulation algorithm.
