Judul: Kajian Myelositomatosis pada Ayam Kampung Betina.
Abstrak: Kejadian berbagai jenis tumor atau neoplasia pernah dilaporkan pada unggas, baik yang telah mengalami domestikasi maupun unggas liar. Salah satunya adalah myelositomatosis yang disebabkan oleh Avian Leukosis Virus subgroup I. Tujuan dari studi kasus ini untuk melihat keberadaan sel myelosit pada sumsum tulang sebagai tempat pembentukan sel-sel darah dan ovarium sebagai media penularan secara vertikal dari induk ke anak. Spesimen dalam studi ini berjumlah 10 ekor ayam yang berumur 4-6 bulan. Hasil pengamatan menunjukkan adanya kelompok-kelompok sel myelosit dalam jumlah beragam pada sumsum tulang dan ditemukannya kelompok sel myelosit pada 9 ovarium. Walaupun sampai saat ini belum ada kajian khusus mengenai histologi ayam kampung namun hasil pengamatan secara histopatologi menunjukkan adanya indikasi ayam terkena myelositomatosis.

Judul: Kajian myelositomatosis pada ayam broiler sebagai imunosupresor
Abstrak: Myelocytomatosis or myeloid leucosis (ML) is a kind of neoplastic disease caused by Avian leucosis virus subtype J (ALV–J) infection, which often found in chickens worldwide. Myelocytomatosis in chickens cause reduced productivity and increased mortality in flocks. The aim of this study was to make pathological assessment of ML occurred in a broiler farm. Increased mortality with breathing difficulty (dyspnoea) were noted in broiler flocks aging 7 and 14 days. Afterwards necropsy was performed and organs were sampled for histopathological examinations. All organs were embedded in paraffin, sectioned at 5 μm, and stained with hematoxylin and eosin (for morphology), periodic acid–Schiff for carbohydrates, and Masson trichrome for collagens. Histopathological findings of ML included scattered myeloid cells depositions in the interstitium and perivascular area of kidney, liver, lung, and heart. Additionally, high percentage (>70%) of myeloid cells were found in the bone marrow. In addition to ML in various organs, there were invasive granulomatous pneumonia comprises of poorly demarcated fibrous bands, and septate fungal hyphae which consistent with the morphology of Aspergillus spp. Myelocytomatosis were also detected in the breeder flocks aging 29 weeks, notably in liver and ovaries. These findings suggest that vertical ML transmission may cause immunosupression which lead to invasive granulomatous lesion. Invasive granulomatous pneumonia with ML has never been documented in poultry.

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.
