Judul: Pemanfaatan luaran RegCM3 untuk kajian dampak perubahan iklim terhadap perubahan waktu dan pola tanam padi di Jawa Barat
Abstrak: Climate change could be indicated by the shifting in the patterns of climate variables, such as air temperature and rainfall in the long term. The changes of those two variables could affect water balance, which will impact agricultural management systems, especially related to planting time and cropping patterns. This research aims to study future climate change projections and their impact on the changing of planting time and cropping patterns in West Java. The analysis is based on the Thornhtwaite Mather water balance model calculated by using climate data from the output of regional climate model, namely RegCM3. The RegCM3 output shows a rainfall decrease in West Java ranging from 4.53% to 8.16%. The changes of rainfall pattern in the future are projected to increase during wet seasons and will decrease during transitional and dry seasons, with shorter rainfall peak of wet seasons and longer peak of dry seasons. The temperature in West Java is also projected to change in the future showed by a very significant increase compared to the reference period. Based on the observational data, the temperature trends in the region has showed an increase, ranging from 0.0174 °C/year to 0.0216 °C/year during 1985-1999 periods. Water balance are analyzed on three different areas in West Java based on the rainfall patterns defined by cluster analysis (cluster C1, C2, and C3). C1 rainfall pattern is a region with low rainfall, C2 with medium rainfall, and C3 with high rainfall. Based on the calculation of water balance in the future under SRES A1B scenario, it is shown that the planting time will be potentially delayed from 40 to 51 days especially in C1 and C2 regions, while there is no change of planting time in C3 region. In addition, the cropping pattern will also change in the future due to the change in water balance. Initial determination of growing season will experience a setback, which ranges from one to two of ten days period in C1 and C2 region with cropping patterns changing from paddy-paddy-fallow to paddy-fallow-fallow in C2 region.

Judul: Proyeksi Klasifikasi Iklim Oldeman Pulau Jawa berdasarkan Skenario Perubahan Iklim
Abstrak: Dampak perubahan iklim di masa depan mengancam Pulau Jawa sebagai sentra produksi padi dan menjadi tantangan dalam pemenuhan kebutuhan pangan di masa depan. Perubahan iklim akan berdampak pada perubahan zona agroklimat dan pola tanam tanaman pangan di Pulau Jawa. Tujuan penelitian ini yaitu menganalisis perubahan distribusi bulan basah dan bulan kering Pulau Jawa di masa depan dengan proyeksi perubahan iklim berdasarkan klasifikasi iklim Oldeman dan menganalisis hubungan perubahan zona agroklimat dengan pergeseran awal musim di Pulau Jawa. Data yang digunakan yaitu data curah hujan bulanan periode current (1971–2000), future (2030-an dan 2050-an), dan data prakiraan awal musim hujan dan kemarau luaran BMKG. Hasil penelitian menunjukkan, proyeksi iklim Oldeman tahun 2030-an dan 2050-an mempunyai pola distribusi yang mirip dengan periode 1971–2000 yaitu daerah terbasah tersebar di bagian barat dan selatan sedangkan daerah terkering tersebar di bagian tengah, timur dan utara Pulau Jawa. Sebagian besar daerah di Pulau Jawa dalam empat tahun terakhir cenderung mengalami pergeseran awal musim kemarau dan hujan yang mundur dari normalnya (rata-rata tahun 1981–2010). Prakiraan periode musim kemarau cenderung lebih panjang dan periode musim hujan cenderung lebih pendek sesuai dengan sebaran tipe iklim di masa depan. Proyeksi dengan skenario RCP4.5 dan RCP8.5 untuk periode tahun 2030-an maupun 2050-an memiliki sebaran tipe iklim kering (D dan E) yang lebih luas dibandingkan tahun 1971–2000 sedangkan tipe iklim basah (A) terlihat sebarannya semakin mengecil.

Judul: Studi Kasus Liver Neoplasia pada Anjing Shih Tzu
Abstrak: Liver neoplasia is the excessive and uncontrolled replication of hepatocytes that forms nodules visible in ultrasonography. The purpose of this study is to study and discuss the characteristic, diagnosis and treatment of liver neoplasm through the interpretation of ultrasonography and hematology in a Shih Tzu dog. Ultrasonography is conducted with a Chison Q8 ultrasound machine with a 5 to 7 MHz frequency convex probe on lateral recumbency. The blood cells, liver enzymes and nodules sizes were the main parameters in this study. The results in the period of three years from 2021 to 2023 were interpreted and supported with secondary data sources. The Shih Tzu dog is 14 years old in the year 2023 with a body weight of 5.21kg. No obvious clinical signs were observed during previous examinations. However, lethargy, vomiting and anorexia were recorded in its latest examination. Thrombocytosis, granulocytosis, high liver enzymes and hypoglycemia, which are some of the neoplastic clinical manifestations were also presented by this patient. Besides, liver neoplasm, spleen neoplasm and biliary sludge were the sonogram findings of this patient. The liver and spleen neoplasm was observed stable, while the biliary sludge volume fluctuated. The treatment strategy recorded is Ondansetron, Samylin®, Ornipural and Ursodeoxycholic acid.
