Abstract

Kabuyutan Ciburuy pada mulanya merupakan suatu tempat berkumpulnya para cedikiawan dan pelajar untuk berbagi berbagai ilmu pengetahuan dan kebijaksanaan pada kejayaan jaman pemerintahan Sunda, sekitar abad XIV sampai XVI. Setelah masuknya pemerintahan Mataram Islam ke wilayah Jawa Barat dan diterapkannya politik etis kolonial Belanda pada awal abad XX, aksara Sunda kuno dan kegiatan mandala perlahan-lahan mulai punah. Namun berbagai upaya telah dilakukan untuk melestarikan cagar budaya Sunda kuno tersebut. Makalah ini memaparkan rancang bangun aplikasi mandala sebagai inovasi baru dalam melestarikan cagar budaya di Kabuyutan Ciburuy. Dengan adanya aplikasi ini, upaya revitalisasi dari fungsi Kabuyutan Ciburuy sebagai lembaga pendidikan formal jaman kerajaan di Sunda dapat diaktifkan kembali. Aplikasi Mandala dikembangkan dengan pendekatan user centered design untuk memastikan keberdayagunaan aplikasi. Beberapa fitur yang disematkan ke dalam aplikasi mandala adalah visualisasi naskah Sunda kuno, transliterasi, terjemahan, galeri, dan hasil riset terkait Kabuyutan Ciburuy. Selanjutnya, fitur permainan dengan tema kesundaan ditambahkan untuk meningkatkan ketertarikan masyarakat untuk belajar budaya Sunda dengan lebih menarik dan menyenangkan. Metode pararel disain dan pengujian usabilitas terhadap dua kelompok telah dilakukan dan  menunjukan hasil bahwa tingkat learnability sebesar 81,34 % dan satisfaction sebesar 77,67%.

Abstract

The variety of image quality of old Sundanese documents can be a real challenge for the process of text line segmentation. This paper describes the results of the investigation of two text line segmentation methods against several collections of Sunda document images, ie projection profile method and Seam Carving method. The deep investigation is done on handwritten documents written on lontar and paper media. The comparative experimental study was used as an investigative methodology in this study. Both methods is tested their performance capability on colored images and binary images using the evaluation matrix provided in handwriting segmentation competition ICDAR 2013. Experimental results show that projection profile method can work optimally on binary image and the type of writing is relatively horizontal. While the Seam Carving method is able to segment the lines in a non-linear manner and produce performance above 80%. With the added of binarization process in the pre-processing stage, the performance of Seam Carving method can increase up to 99% and the number of segmented lines is close to the number of groundtruth lines.

Abstract

Makalah ini memaparkan percobaan evaluasi komprehensif terhadap aplikasi virtual reality (VR) bertipe semi-immersive dari sisi heuristik disain antarmuka aplikasi, peningkatan kemampuan kognitif, dan peningkatan motivasi belajar ketika aplikasi digunakan dalam proses pembelajaran. Evaluasi terhadap disain antarmuka VR ini menggunakan metode heuristik yang diusulkan oleh Sutcliffe, yaitu sebanyak dua belas prinsip. Selain faktor usabilitas, evaluasi heuristik ini mampu memberikan panduan evaluasi dengan memperhitungkan faktor keberadaan pengguna ketika berada dalam lingkungan maya. Hasil proses inspeksi evaluasi heuristik ini adalah penggabungan nilai evaluasi dari tiga orang penilai. Hasil evaluasi menunjukan bahwa secara heuristik aplikasi BIOTALAUT VR sudah merepresentasikan kondisi lingkungan bawah laut dengan baik. Namun ada beberapa fitur disain yang perlu diperbaiki, yaitu interaksi antar objek, grafik objek 3D biota dan fungsi kontrol. Sedangkan, proses evaluasi dari segi peningkatan kemampuan kognitif diimplementasikan pada 30 siswa tingkat sekolah menengah pertama melalui kegiatan pretes dan postes kemudian dianalisa secara statistik. Selain pretes dan postes, siswa juga mengisi kuisioner untuk mengetahui tingkat motivasi belajar setelah menggunakan aplikasi. Kemudian, setelah aplikasi digunakan pada proses pembelajaran, terdapat perbedaan kemampuan kognitif yang signifikan ke arah positif dengan nilai sig-value sebesar 0.448 dan peningkatan motivasi dilihat dari nilai rata-rata central tendency sebesar 4.49. Adapun hasil evaluasi ini dapat digunakan sebagai bahan pertimbangan dalam pengembangan aplikasi selanjutnya khususnya dari sudut pandang disain antarmuka aplikasi maupun dari konteks pembelajarannya. Selain itu, kejadian munculnya gejala cybersickness pada pengguna juga ditelaah dan dilaporkan dalam penelitian ini. Adapun posisi gerakan pengguna saat menjalankan aplikasi VR dan perangkat keras yang dipakai menjadi aspek utama yang menyebabkan cybersickness tersebut.Kata Kunci: cybersickness, evaluasi usabilitas heuristik, , kemampuan kognitif, motivasi belajar, virtual reality

Abstract

Penelitian ini berisikan tentang sistem deteksi wajah pada gambar yang terdiri dari berbagai posisi wajah pada sekumpulan orang. Metode yang digunakan adalah Kanade- Lucas-Tomasi dan Viola-Jones. Metode Viola-Jones memiliki tingkat keakuratan cukup tinggi, di atas 90%. Metode Kanade- Lucas-Tomasi juga memiliki tingkat keakuratan yang baik, namun membutuhkan waktu lebih lama untuk mendeteksi wajah dibandingkan metode Viola-Jones. Deteksi wajah diperlukan untuk mengetahui jumlah orang dalam sebuah kerumunan, karena bagian kepala biasanya terlihat dalam kerumunan yang penuh sesak. Data penelitian didapat dari hasil foto kegiatan di lab, kegiatan mahasiswa yang sedang ujian, dan kegiatan mahasiswa di kelas. Tujuan dari penelitian ini adalah untuk menentukan sudut yang masih bisa dianggap sebagai wajah dengan menggunakan metode Viola-Jones dan Kanade-Lucas- Tomasi.

Abstract

The technology development allows people to more easily communicate and convey information. The current communication media can facilitate its users to send and receive digital data, such as text, sound or digital image. But in terms of security, communications media not always ensure the confidentiality and authentication of data traffic. Most people rely solely on the security provided by the communications media providers in securing their data, which is essentially still inadequate. This paper presents the development of a data security framework by applying the principles of cryptography and digital signatures, such as authenticity, integrity, and data confidentiality. The application is designed using the SHA-256 algorithm as digital signature, AES algorithm as file encryption, and RSA algorithm as asymmetric key in digital file distribution and signature. Then, several simulation testing was performed to ensure the robustness of the framework. Furthermore, we also evaluated the speed of framework based on CPU and memory capacity. Based on the experiment, our proposed framework can be a reliable solution for securing data in data transaction

Abstract

Flooding is a natural disaster that often occurs, it is not surprising that floods are one of the problems that must be resolved in various countries, one of which is Indonesia. Flood is very detrimental to the public because the impact could be the loss of material and non-material. A flood protection system is needed and must be managed properly. This aims in management of flood protection systems often requires efficient cost control strategies that are the lowest possible long-term costs, but still meets the flood protection standards imposed by regulators in all plans. In this paper a flood protection strategy is modeled using Adjustable Robust Optimization. In this approach, there are two kinds of variables that must be decided, i.e., adjustable and non-adjustable variables. A numerical simulation is presented using Scilab Software. Keywords: Flood Protection Strategy, Uncertainty, Adjustable Robust Optimization, Scilab Software.
