Judul: Evaluasi Skenario Ketersediaan Air Terhadap Potensi Produksi Padi Saat Fenomena El-Nino Southern Oscillation (ENSO). Studi Kasus: Kabupaten Subang.
Abstrak: Fenomena ENSO besar pengaruhnya terhadap penurunan hasil padi sawah di Indonesia. Sehingga dapat berdampak kepada ketahanan pangan di Indonesia. Penelitian ini bertujuan untuk melihat potensi hasil padi berdasarkan tanggal tanam yang sesuai untuk mendapatkan hasil yang optimum saat terjadinya fenomena ENSO. Dengan menggunakan model simulasi Aquacrop. Data masukkan terdiri dari data iklim harian 30 tahun (1986-2015), data profil tanah, data karakteristik tanaman padi, serta data management pengairan irigasi. Simulasi dilakukan menururt waktu tanam dari Januari sampai Desember dengan selang tanam 10 harian. Berdasarkan survei permasalahan iklim utama yang dihadapi petani adalah kekeringan. Hasil simulasi menunjukkan opsi untuk mengatasi kekeringan dengan pengaturan irigasi yang efisien. Secara umum waktu tanam padi sawah irigasi utuk penanaman musim hujan (Oktober-Maret) dapat mencapai 6 ton/ha berbeda pada penanaman musim kemarau hanya berkisar 4 ton/ha pada kondisi normal. Sedangkan pada saat terjadi EL Nino penanaman pada musim hujan tidak berpengaruh terhadap hasil produksi tetapi berpengaruh saat memasuki musim kemarau dengan produksi hanya mencapai 3 ton/ha. Saat La Nina memberikan hasil produksi yang sama dengan kondisi normal tetapi pada bulan bulan tertentu menghasilkan produksi diatas rata-rata. Sedangkan pada sawah tadah hujan penanaman pada musim hujan mencapai 6 ton/ha, pada musim kering mecapai 1 ton/ha pada tahun normal. Pada saat terjadi El Nino hasil produksi saat musim hujan dan kemarau adalah 5 ton/ha dan 0 ton/ha. Sedangkan pada kondisi La Nina hasil produksi sama dengan kondisi normal.

Judul: Analisis Dampak ENSO (El-Nino Southern Oscillation) Terhadap Tingkat Kekeringan Untuk Tanaman Pangan dan Palawija (Studi Kasus : Sulawesi Selatan)
Abstrak: Climate and weather variability is a condition of long-term climate change is marked by fluctuations and deviations from normal conditions. One reason is the ENSO (El-Nino Southern Oscillation) which affects the drought. This research was conducted with the aim to determine and analyze the level of drought in South Sulawesi due to the influence of ENSO and compare the production of food crops and crops in a normal year and ENSO. Drought index is calculated based on the Palmer method by using rainfall data, air temperature and soil humidity as inputs. Based on the drought index calculated using the Palmer method, areas with monsoon rain patterns have a range of values between -22.71 to dryness 18.23, equatorial patterns ranged from -4.03 to 5.07, and the local patterns ranged from -8.57 to 10.07. Verification test results of the drought index of crop production data show that each ENSO event is always followed by a decline in rice production, especially of rice fields. As for crops, crop production generally tended to increase in every ENSO event because most crops are plants that are resistant to drought, particularly local varieties that have adapted well to its environment. Thus, the influence of ENSO drought can affect the production of food crops and crops.

Judul: Studi Histopatologi Organ Hati Hamster (Mesocricetus auratus) yang Diinfeksi Coxiella burnetii
Abstrak: Coxiella burnetii (C. burnetii) is a bacterial like organism that causes Query fever. The aim of this study was to describe the liver histopathology of hamsters after infected by C. burnetii intraperitoneally. Hamster were divided into two groups. All hamster liver were collected for histopathological examination using hematoxylin-eosin staining (HE) and immunohistochemical staining (IHC). HE staining results in hamsters group I which were injected with C. burnetii’s antigen showed 3 out of 4 has granuloma which are typical of C. burnetii infection. All hamsters group II which were injected with hamsters group I’s spleen extracts showed granuloma in microscopic observation. IHC staining revealed all hamsters liver has positive result. Beside granuloma lesion, all hamster’s liver show acute hepatitis symptoms. The microscopic lesion of acute hepatitis showed the inflammatory cell accumulated in liver perifer, degeneration of hepatocytes cells, activation of lymphoid follicles, as well as congestion in small and large blood vessels.
