Image enhancement (IE) is very important in the field where visual appearance of an image is the main. Image enhancement is the process of improving the image in such a way that the resulting or output image is more suitable than the original image for specific task. With the help of image enhancement process the quality of image can be improved to get good quality images so that they can be clear for human perception or for the further analysis done by machines.Image enhancement method enhances the quality, visual appearance, improves clarity of images, removes blurring and noise, increases contrast and reveals details. The aim of this paper is to study and determine limitations of the existing IE techniques. This paper will provide an overview of different IE techniques commonly used. We Applied DWT on original RGB image then we applied FHE (Fuzzy Histogram Equalization) after DWT we have done the wavelet shrinkage on Three bands (LH, HL, HH). After that we fuse the shrinkage image and FHE image together and we get the enhance image.

Dengan berkembangnya teknologi informasi, sering sekali terjadi penyelewengan dokumen terutama pada dokumen-dokumen cetak. Dokumen merupakan salah satu data yang sangat penting, karena dokumen merupakan sumber informasi yang diperlukan oleh suatu instansi, organisasi, negara, maupun individu. Tanpa dokumen, maka seseorang akan kehilangan data-data yang diperlukan untuk kegiatan di masa yang akan datang. Pemalsuan dokumen sangat mudah dilakukan dengan cara meniru bentuk serta isi dari suatu dokumen. Penelitian sebelumnya pernah dilakukan, namun dalam objek yang berbeda. Pemalsuan dokumen dapat diatasi dengan menggunakan Quick Response (QR) Code. QR Code mampu menyimpan semua jenis data, seperti data angka/numerik, alphanumeric, biner, kanji/kana. Selain itu QR Code memiliki tampilan yang lebih kecil daripada barcode. Untuk dapat membuat QR Code suatu dokumen maka dibuatlah sebuah aplikasi yaitu aplikasi Validasi Dokumen. Aplikasi Validasi Dokumen dirancang dengan menggunakan metode waterfall serta menggunakan perancangan Unified Modelling Language (UML). Bahasa pemrograman yang digunakan yaitu bahasa pemrograman PHP: Hypertext Preprocessor (PHP) dengan database MySQL. Sebelum QR Code dibuat, terlebih dahulu data dokumen dienkripsi dan kemudian dijadikan QR Code. Hasil pemindaian QR Code berupa Uniform Resource Locator (URL) yang mengarah pada data dokumen. Ketika URL dijalankan pada web browser, sistem melakukan deskripsi pada URL, kemudian dicocokkan dengan database, dan selanjutnya ditampilkan ke web browser. Hasil akhir aplikasi Validasi Dokumen berupa QR Code yang digunakan untuk menyimpan URL yang  menunjukkan bahwa dokumen memang benar-banar dokumen yang resmi (bukan ilegal) dari suatu instansi. Pada uji coba penelitian ini juga dilakukan perbandingan kinerja dengan 3 aplikasi yang sejenis, 3 aplikasi pembanding tersebut dipilih karena memiliki hasil visual QR Code yang hampir mirip, namun jika dilakukan scanning memiliki hasil yang berbeda, karena fiturnya juga berbeda. Berdasarkan hasil pengujian dengan 3 pembanding aplikasi yang sejenis, dengan menggunakan aplikasi yang diusulkan dalam penelitian ini, pemalsuan dokumen dapat dihindari dengan menggunakan aplikasi Validasi Dokumen selama tidak ada ikut campur orang dalam (superadmin/admin) dalam melakukan praktik pemalsuan dokumen. Pada penelitian selanjutnya dapat dilakukan perbaikan kelemahan aplikasi ini, yaitu agar tidak menampilkan URL, namun hasil pemindai QR Code, langsung dapat menampilkan detail isi dokumen.

Business Card is the most efficient, effective and appropriate tool for every business men no matter they are owners, employees, more over marketers to provide information about their businesses. Unfortunately, it is very difficult to bring and manage business card in large numbers also to remember the face of the business card owner. A Business Card application need to be built to solve all those issues mentioned above. The Application or software must be run in media which can be accessed anywhere and anytime such as smart phone. Kuartu is as business card application run in mobile devices. Kuartu is developed using object base modeling for mobile sub system. The platform of the mobile sub system is android, as it is the most widely used platform in the world. The Kuartu application utilizing NFC and QR Code technology to support the business card information exchange and the Chatting feature for communication. Based on the experiment and test using black box methodology, it can be concluded that Kuartu application makes business card owner to communicate each other easily, business card always carried, easy to manage the cards and information of the business card owner can be easily obtained. Index Terms— Business Card, Android, Kuartu, NFC, QrCode, Chatting.

Abstract Sediment cores were collected in Lake St. Clair in 1985 and in the St. Clair River in 1986 to investigate the horizontal and vertical distribution and association of Hg in the sediments. A layer of recent sediment up to about 35 cm thick was differentiated by the geochemical composition and visual appearance from the underlying glacial-lacustrine deposits. The concentration of Hg in the surficial sediments in Lake St. Clair was lower in 1985 (<0.025 to 1.200 µg/g) than that found in 1974 (<0.20 to 3.00 µg/g). Up to 8.30 µg/g of Hg were found in the sediments collected from the nearshore area at Sarnia, Ontario, in the St. Clair River in 1986. The concentrations of Hg ranged from 5.05 to 16.00 µg/g in different sand-sized fractions (0.063 to 0.350 mm) of the sediment. The concentration of Hg was 17.80 µg/g in the silt-clay size fraction (<0.063 mm). No relationship was found between the concentration of organic matter and Hg, and the concentration of silica and Hg in the St. Clair River sediments. The results indicated a relationship of Hg with particles of different mineralogical composition. Up to 3.72 µg/g Hg was found in the surface sediment in Chenal Ecarte. The greatest concentration of Hg (13.15 µg/g) existed in the 0.350 mm particle size fraction, which consisted mainly of small pieces of decaying wood. A good relationship was found between the concentration of Hg and organic matter in the sediment at this area.
