Judul: Development of semi dynamic cropping calendar for Indramayu using Pacific sea surface temperature
Abstrak: Agriculture is a very important sector in Indramayu’s economy. Approximately 53.52% of Indramayu residents are involved in agriculture. Indramayu has 119.752 Ha (58% of the total area) cultivated as rice fields which generates the majority of the district’s income. Most of the farmers use a traditional cropping method called Pranata Mangsa, which is based on periodic natural events and Primbon, but not climate variability. Climate variability has become a major obstacle to achieving a successful harvest, because it can affect the timing of planting and length of the growing season, which leads to drought and flood vulnerability. The planting date and growing season can be predicted using monthly sea surface temperature (SST) anomalies in Nino 3.4. The August SST anomalies can describe the planting date better than the growing season, which are demonstrated best in Lohbener with R-Sq = 45% with forecast skill reach = 84% and 92% for advanced and delayed planting date. Knowing the planting date and growing season length produces a more efficient cropping calendar, which includes details such as when to prepare the land, plant seeds, and harvest. This cropping calendar is expected to reduce the impacts of climate variability by providing a more efficient cropping pattern and avoiding potential harvest failures.

Judul: Pengelolaan risiko iklim pada sistem usaha tani berbasis padi melalui pemanfaatan kalender tanam dinamik
Abstrak: El-Nino events can lead to decreased production of rice, due to the addition of the planting area is experiencing drought and loss yield. Early withdrawal of the rainy season could lead to the resignation of a second crop. This second crop is susceptible to drought. Therefore, the scheduling of planting taking into account the possibility of extreme climate events are contained within a planting calendar is one solution. Research preparation of the planting calendar has been started since 2007 (Las et al, 2007) by the Ministry of Agriculture. Output produced in the early years, a map of the plant which is divided into four scenarios, using historical data. On the other hand, Boer et al (2007) also researched the planting calendar with use decision and bayesian network. However, the resulting decision regarding just planting time only. Therefore, to develop a planting calendar that has been generated, the research done by adding the decision issued by measuring the utility function as an approach, in addition to overcome the problem of drought due to improper planting time. This study aimed to look for alternative cropping patterns ideal economically advantageous in terms of a combination of rice cultivation (planting time, fertilizer, irrigation, varieties) on a farm in a particular season, which gives the maximum production with minimal loss rate.

Judul: Leukemia pada kucing
Abstrak: Leukemia pada kucing adalah suatu penyakit yang sangat patogen, disebabkan oleh sejenis virus. Virus ini dikenal sebagai Feline Leukemia Virus atau FeLV. FeLV ini oleh beberapa ahli dikatakan hanya bersifat ganas pada hewan kucing. Penularannya bisa secara horizontal maupun congenital. Kucing pada semua tingkat umur dapat terserang oleh FeLV ini. Khusus pada bentuk "thymic leukemia", virus ini hanya menyerang anak-anak kucing berumur diba- wah 1 tahun. Kucing-kucing liar atau yang tidak terpeli- hara jarang sekali terinfeksi FeLV. Selain dari serangan virus FeLV itu sendiri, maka penyakit leukemia ini bisa disebabkan oleh beberapa fak- tor yang sudah ada dalam tubuh hewan dan sangat menunjang perkembangan penyakit ini, yaitu antara lain tumor, agen toksik, cedera oleh kecelakaan dan gangguan hemopoiesis. FeLV menyerang sel-sel darah dalam tubuh hewan se- hingga pembentukan darah berjalan tidak normal. Terlihat sel-sel darah yang belum dewasa sudah beredar dalam sir- kulasi darah. Bentuk dan jumlahnya tidak lagi seimbang dalam tubuh hewan kucing tersebut. Gejala klinis antara lain kekurusan, ikterus, anemia, lemah, anoreksia, dyspnoe, sulit menelan, batuk, dan membran mukosa pucat. Selain itu kelenjar pertahanan tubuh juga membengkak, kemudian terjadi hepatomegali, spleenomegali dan pembengkakan pada ginjal. Terbentuk massa tumor pada beberapa tempat. Secara biopsy pada sumsum tulang akan terlihat be- berapa perubahan. Sumsum tulang berwarna merah tua atau abu-abu. Konsistensinya lunak dan terdapat banyak sekali memproduksi sel darah putih. Melalui gambaran darah leukemia ini lebih mudah didiagnosa. Jumlah retikulosit rendah sekali. PCV 8-15%, hemoglobin menurun, sel darah putih (WBC) meningkat, lim- fosit meningkat, Alfaglobulin juga ada peningkatan, dan banyak eosinofil yang belum dewasa beredar dalam darah…dst
