Judul: Penerapan teknik watermarking untuk penandaan hak cipta pada peta vektor dengan format DXF
Abstrak: Drawing Interchange Format (DXF) is one of the general file in the field of the vector image commonly used for making maps. The DXF format is a tagged data representation of all the information contained in an AutoCAD drawing (DWG) file. Tagged data means that each data element in the watermark is preceded by an integer number called the group code. The study was carried out because there is still no tools of labeling the copyright on digital mapping using DXF file. This study aims to generate an application for copyright labeling on vector map with DXF format that can be applied to any types of spatial objects in the map. The technique used is changing the code inside the vector image. The insertion of the watermark is done by utilizing ENTITIES section by multiplying objects for sets of binary values. The results showed that the image after the watermarking insertion process is the same as the original vector image. Embedded watermark is resistant to rotation and scaling, however it has the possibility of one-third to be broken in the attack on specific object. This study has successfully implemented watermarking technique for copyright labeling on the vector map with DXF format.

Judul: Perbandingan Teknik Watermark CDMA dalam Domain Spasial dan Domain Wavelet pada Citra Digital
Abstrak: Presentation of data and information has been progressing quite rapidly, so data and information has been widely presented in digital format. Problems began to emerge as widespread digital data need to be protected. This is related to ownership, copyright, or authenticity issues. This study tries to provide solutions to these problems by applying the digital watermarking with Code Division Multiple Access (CDMA) technique. This technique uses a digital image composed of a cover image and two types of watermark (initial and copyright). There are two stages in this research, the first is trying to insert two types of watermark on the cover image in two different domains, namely spatial domain and wavelet domain. Once inserted, the watermark is extracted back to be compared with the original watermark. The second is attempting to insert an initial watermark on the cover image in two different domains, then giving some distortion of the image to be tested for resistance. After that, the watermark is extracted again. From the experiment results, it is known that wavelet domain CDMA is superior in terms of quality of the extracted watermark, processing time, and resistance to distortion (JPEG compression and gamma correction). While CDMA coding spatial domain is simpler and has a resistance to gamma correction only.

Judul: Patologi Dan Patogenesa Pneumonia Mycoplasma Pada Babi
Abstrak: Pneumonia Mycoplasma adalah bentuk pneumonia paling sering dan umum diantara bentuk pneumonia lainnya pada babi, disebabkan oleh Mycoplasma hyopneumoniae (M. suipneu- moniae). Penyakit menyebar hampir di seluruh dunia dan merupakan penyebab kerugian ekonomi tertinggi diantara pe- nyakit babi lainnya (Macpherson dan Hodges, 1985). Penularan dari hewan satu ke hewan lain melalui udara yang tercemar M. hyopneumoniae atau kontak langsung dengan ekskresi alat respirasi hewan penderita. Induk semang ala- mi sampai sekarang yang diketahui adalah babi. Anak babi sering terinfeksi dari induknya. Oleh karena itu infeksi selalu timbul dari satu generasi ke generasi berikutnya, sehingga apabila M. hyopneumoniae sudah menyerang suatu populasi cenderung bersifat endemik. Gejala klinis Pneumonia Mycoplasma Pada Babi atau "Mycoplasmal Pneumonia Of Swine" (MPS) adalah batuk kering, nafsu makan turun, hambatan pertumbuhan dengan morbiditas tinggi tetapi mortalitasnya rendah. Limfonodus bronchial dan mediastinal bengkak dan oedem. Kerugian ekonomi beru- pa penurunan rasio konversi makanan dan bobot badan, serta umur untuk siap dipotong rata-rata 2-3 minggu lebih lama dari biasanya (Baskerville, 1981). Lesio-lesio paru-paru paling sering ditemukan di lobus cardiacus dan lobus apicalis berupa daerah konsolidasi merah muda keabu-abuan yang dipisahkan secara jelas dari bagian paru-paru sehat. Komplikasi dengan infeksi sekunder bakteri, cacing paru-paru dan virus memperparah lesio- lesio sebelumnya. Pengobatan infeksi Mycoplasma hyopneumoniae sulit menghilangkan agen penyakitnya. Meskipun begitu obat yang dapat diberikan bersama makanan, minuman atau injeksi da- pat mengurangi keparahan lesio-lesio yang timbul. Vaksinasi yang pernah dilakukan sampai saat ini tidak memuaskan…dst
