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: Determination of The Rice Cropping Calendar based on ENSO (El Niño Southern Oscillation) and IOD (Indian Ocean Dipole) phenomena in Monsoon and Equatorial Regions.
Abstrak: Increasing fluctuation and more frequent climate anomaly in the last decade due to ENSO and IOD phenomena has severe implications on food crops. Therefore, a sound planting season adaptation strategy is needed in the efforts to enhance sustainable food security. Research has been conducted in West Java (Monsoon rainfall pattern) and West Sumatera (Equatorial rainfall pattern)province. Analysis of the correlation between ENSO and the IOD with rainfall has been carried out to find the relationship between ENSO and the IOD with rainfall in the period from December to February, March to May, June to August, and September to November. Water Satisfaction Index and irrigation rice-field water balance was used to obtain optimal planting time. Artificial Neural Network was used to rainfall prediction for improvement of cropping pattern planning. Interviews with farmers to study the adaptation measures of farmers against the impact of drought. The spatial distribution of partial correlations between rainfalls with ENSO and IOD over West Sumatera and West Java indicated a significant impact on rainfall anomalies along the period of September – November. The ENSO and IOD events had a wider impact in West Java, which was known as a monsoon rainfall pattern especially over northern part of West Java. On the other hand, there was only a little impact of the ENSO and IOD on rainfall anomalies in the south-western West Sumatera. In the period of June-November the impact to rice- field in West Sumatera was only about 20% while, the impact in West Java could reach up to 80%. In the region affected by strong ENSO and IOD like Indramayu, impact of ENSO and IOD has delayed the peak of early planting by more than 6 dekads. The peak of early planting occurred in November III/ December I could reach up 30% due to ENSO and 35% due to IOD. The period-stratified ENSO variability had delayed planting time by 2 to 5 dekads in monsoon rainfall pattern (West Java) and 1 dekads in equatorial pattern (West Sumatera). Meanwhile, the period-stratified IOD variability in West Sumatera and West Java had delayed planting time by 1 to 2 dekads. Result of the prediction showed that the period of September 2010 to February 2011 was above normal. Wet conditions resulted in the potential of planting time 1 dekads earlier on rain-fed land and 2 dekads earlier on irrigated land than in normal conditions. Adaptation by farmers to climate anomalies was more apparent in a monsoon rainfall pattern area with various efforts in the utilization of water resources, i.e. pumping technology, the adjustment of planting time by 2-3 dekads and changing crop rotation from paddy-paddy-palawija into paddy-palawija.

Judul: Telaah Histopatologi Urolithiasis Pada Kucing
Abstrak: Urolithiasis adalah suatu keadaan dimana ditemukannya batu di dalam saluran urinaria. Batu tersebut dibentuk dalam pelvis ginjal dan bergerak turun sepanjang ureter kemudian masuk ke dalam vesika urinaria dan uretra. Penulisan ini bertujuan untuk mempelajari lebih dalam secara histopatologi tentang kasus kematian seekor kucing dengan urolithiasis yang dinekropsi di Laboratorium Patologi FKH-IPB. Pemeriksaan patologi anatomi menemukan adanya fokal atelektasis paru, dilatasi ventrikel kiri jantung, hidrothoraks, hidroasites, ginjal pueat dan batu-batu berbagai ukuran dengan diameter 0,1-0,5 em pada vesika urinaria yang berdarah. Pada pengamatan histopatologi menunjukkan pembendungan semua organ, nephritis interstitialis kronis disertai bentukan mikrokista dan endapan mineral pada lumen tubuli dan sistitis nekrotik disertai pendarahan yang meluas. Pemeriksaan pada organ paru-paru ditemukan lumen alveolus sebagian mengempis dan sebagian lagi meluas. Dinding alveol menebal akibat adanya akumulasi eritrosit. Sedikit koloni bakteri tampak dalam lumen usus, bercampur dengan epitel usus yang terlepas di ujung viii. Hati mengalami pembendungan, ruangan sinusoid tampak meluas. Beberapa megakariosit tampak di dalam pulpa merah yang menunjukkan adanya aktivitas hematopoetis. Organ jantung tidak menunjukkan adanya perubahan histopatologi yang spesifik.
