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: Teknik Penyisipan Informasi pada Fitur Poligon Peta Vektor Menggunakan Reversible Watermarking
Abstrak: Digital vector maps have high precision. Unfortunatelly, watermarking in digital maps usually cause distortion. This study uses a reversible watermarking technique to overcome this issue. The purpose of this study is to apply a reversible watermarking technique to insert some information into digital maps with the ability to restore the map coordinates prior to insertion. In this study, the file used as the insertion media is a 2D digital map coordinate data in shapefiles and images is used as a the watermark. Reversible watermarking process is done on a vector map with polygon features and each insertion process is only performed on a polygon feature. Features that can be inserted should have larger number of vertices than the number of watermark bits. In this study, the watermark is obtained from the MD5 hash function so that the watermark is fixed at 128 bits. The study shows that information can be inserted to the map and that the coordinates can be restored to the initial coordinates. The quality of the map after the insertion shows a low distortion as reflected by the very small RMSE value.

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
