Judul: Correlation Between Somatic Cell Count and Composition of Sapera Goat Milk
Abstrak: Kualitas dari susu kambing dapat dipengaruhi oleh jumlah sel somatik (JSS). Penelitian bertujuan mengetahui pengaruh JSS terhadap komposisi susu kambing Sapera yang dibudidayakan di Balai Penelitian Ternak Ciawi Bogor. Sampel susu diambil dari delapan ekor kambing Sapera setiap pekan selama tiga pekan. Pemeriksaan dilakukan untuk mengetahui kandungan lemak, berat jenis (BJ), laktosa, protein dan bahan kering tanpa lemak (BKTL) menggunakan milk analyzer, sedangkan pada parameter bahan kering (BK) dilakukan akumulasi jumlah lemak dengan BKTL serta menghitung JSS dengan metode Breed. Data sampel yang didapat, dibagi menjadi 2 kelompok yakni sampel dengan JSS ≤ 1 x 106 sel/ml (kelompok JSS rendah) dan ≥ 1 x 106 sel/ml (kelompok JSS tinggi). Selanjutnya, komposisi antar dua kelompok yang didapat dianalisis menggunakan T-test serta dilakukan analisis korelasi Pearson antara JSS dengan komposisi susu. Hasil menunjukkan perbedaan sangat nyata pada lemak, BJ, laktosa, protein, BKTL dan BK antara kelompok JSS tinggi dan kelompok JSS rendah (P<0,01), sedangkan pada hasil korelasi memperlihatkan JSS memiliki korelasi positif terhadap lemak dan BK serta berkorelasi negatif dengan BJ, laktosa, protein dan BKTL. JSS tinggi menyebabkan penurunan sintesis laktosa dan proteolisis, sehingga menurunkan angka BJ, prosentase kadar protein, laktosa, BKTL dan menaikkan prosentase kadar lemak dan BK., Goat milk quality could be affected by somatic cell count (SCC). Purpose of study was to determine the affect of SCC toward the composition of Sapera goat’s milk which bred in Balai Penelitian Ternak Ciawi Bogor. Samples were taken from eight Sapera goats once every week for three weeks. The SCC calculation used Breed method and milk analyzer was used to examine and determine Sapera goat milk’s fat content, density, lactose, protein and solid non-fat (SNF). Fat and SNF was adding up to count total solid parameter. Data samples then divided in two groups which are sample SCC ≤ 1 x 106 cell/ml (low SCC group) and ≥ 1 x 106 cell/ml (high SCC group). Based on the obtained data, composition between two groups has been analyzed using T-test and correlation between SCC and milk content also has been analyzed using Pearson correlation. Result showed that there was significant distinction between fat, density, lactose, protein, SNF and solid in low SCC group and high SCC group (P<0,01), as the correlation result showed that SCC obtained positive correlation toward fat and solid but had negative correlation toward density, lactose, protein and SNF. High SCC content could reducing lactose synthesis and proteolisis as it reducing density, percentage of protein, lactose, and SNF, also increasing percentage of fat and solid.

Judul: Status of Microb and Somatic Cell Count of Quaternary Milk  from Cijeruk Farm, Bogor and Pondok Ranggon, East Jakarta
Abstrak: Peternakan sapi perah di Kecamatan Cijeruk termasuk salah satu daerah di dataran tinggi dengan jumlah pasokan susu terbanyak di Bogor, sedangkan salah satu peternakan di dataran rendah dengan produksi susu tertinggi berada di Pondok Ranggon, DKI Jakarta. Perbedaan ketinggian lokasi serta kondisi lingkungan di sekitar peternakan dapat mempengaruhi produktivitas sapi perah. Penelitian ini bertujuan mengetahui perbedaan kualitas mikrob dan jumlah sel somatik susu dari peternakan di dataran rendah dan dataran tinggi. Variabel yang diamati dalam penelitian ini adalah Angka Lempeng Total (ALT) mikrob, jumlah Staphylococcus aureus, dan jumlah sel somatik (JSS). Pengujian mikrob dilakukan dengan metode hitung cawan dan penghutungan JSS menggunakan metode Breed. Data yang diperoleh dianalisis secara statistik dengan uji Mann-Whitney U dan Chi-square. Hasil penelitian ini menunjukkan ALT mikrob, jumlah S. aureus, dan JSS pada peternakan Pondok Ranggon lebih tinggi dibandingkan dengan peternakan Cijeruk. Rata-rata ALT mikrob, jumlah S. aureus, dan JSS pada peternakan Cijeruk berturut turut adalah 1,6 x 104 ± 1,5 x 104 koloni/ml, 1,3 x 103 ± 4,2 x 103 koloni/ml, dan 1.795.000,0 ± 1.838.791,4 sel/ml. Rata-rata ALT mikrob, jumlah S. aureus, dan JSS pada peternakan Pondok Ranggon berturut-turut adalah 3,5 x 105 ± 1,0 6 x 10 koloni/ml, 1,7 x 105 ± 6,3 x 104 koloni/ml dan 3.032.222,2 ± 4.348.654,1 sel/ml. Penelitian ini menunjukkan terdapat hubungan antara ketinggian wilayah peternakan dengan S. aureus (P< 0,05). Status mikrob dan jumlah sel somatik dipengaruhi oleh perbedaan daerah peternakan dengan pola pemeliharaan dan keadaan lingkungan yang berbeda., The difference in height of the rearing area and the different conditions of the two areas can affect the productivity of dairy cattle. This research aimed to determine differences in microbial quality and the somatic cell count from farms in the lowlands and highlands. The variables observed in this study were the microbial total plate count (TPC), the number of Staphylococcus aureus, and somatic cell count (SCC). Microbial testing was carried out using the plate count method and the somatic cells count used the Breed method. The data obtained was analyzed statistically using Mann-Whitney U and chi-square. The results of this study showed that TPC, S. aureus, and SCC of Milk from Pondok Ranggon were higher than in Cijeruk. The average of TPC, S. aureus, and SCC in Cijeruk were 1,6 x 104 ± 1,5 x 104 colonies/ml, 1,3 x 103 ± 4,2 x 103 colonies/ ml, and 1.795.000,0 ± 1.838.791,4 cells/ml respectively. The average of TPC, S. aureus, and SCC on the Pondok Ranggon were 3,5 x 105 ± 1,06 x 106 colonies/ml, 1,7 x 105 ± 6,3 x 104 colonies/ml and 3.032.222,2 ± 4.348.654,1 cells/ml respectively. This research showed that the height of the rearing area have relationship with S. aureus (P< 0,05). Microbial status and the somatic cell count are influenced by differences in livestock areas with different maintenance patterns and environmental conditions.

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.
