Judul: Pengembangan Model Penduga Hujan Bulanan Menggunakan Data Satelit TRMM pada Tiga Pola Hujan di Indonesia
Abstrak: Rainfall is one of the atmosphere parameters which is quite difficult to predict because of its very high variability on space and time. The recent development of rainfall observation technology nowadays is using rainfall satellite. This satellite has near real time rainfall monitoring, wide coverage and fast access. In this study, climatological analysis of rainfall pattern, statistical analysis to evaluate and validate TRMM data using selected ground stations and TRMM data, development of correction factor for TRMM data and monthly rainfall prediction using ARIMA model, have been done in three regions with different rainfall pattern. Those areas are monsoonal pattern in Lampung, East Java and Kalimantan Selatan; equatorial pattern in North Sumatera and West Kalimantan; and local pattern in Maluku. The validation analysis showed very high correlation with the gauge data for monsoonal pattern area (>0.80), high correlation for equatorial (>0.60) and local pattern area (>0.75). Each pattern area has a correction equation. In general, the error of corrected TRMM data decreased for monsoonal, equatorial and local pattern. The model of monthly rainfall prediction has been developed for corrected TRMM data with 95% level significance. The verification of model showed high coefficient correlation (r) in local pattern and monsoonal pattern, but lower on equatorial pattern.

Judul: Validasi Data Curah Hujan Global Satellite Mapping of Precipitation (GSMaP) pada Tiga Pola Hujan di Indonesia.
Abstrak: Keterbatasan data observasi seperti data tidak cukup panjang, tidak lengkap/kosong, dan sebaran stasiun yang kurang merata menyebabkan analisis dan prediksi hujan sulit dilakukan. Salah satu cara untuk mengatasi keterbatasan tersebut adalah penggunaan data satelit seperti GSMaP, namun data satelit harus divalidasi sebelum digunakan. Penelitian ini bertujuan untuk memvalidasi data hujan GSMaP terhadap data observasi pada tiga pola hujan di Indonesia. Melalui analisis data time series diketahui data hujan GSMaP cenderung memiliki nilai yang lebih kecil dibandingkan data observasi, namun memiliki pola data yang hampir sama pada ketiga pola hujan. Selain itu, GSMaP juga mampu menduga hari hujan dengan cukup baik. Berdasarkan karakteristik spasial dan temporal, data GSMaP memiliki kemiripan dengan observasi pada mode 1 dan 2. Sedangkan berdasarkan analisis skala waktu, data GSMaP memiliki variabilitas iklim yang dimiliki data observasi pada ketiga pola hujan. Berdasarkan karakteristik spasial, temporal dan skala waktu, data GSMaP dapat digunakan untuk analisis variabilitas iklim yang terjadi di daerah tropis seperti monsun, ITCZ, dan MJO.

Judul: Pengaruh Penambahan Bio Adenosin Tri Phosphat terhadap Profil Kinetik dan Efektivitas Enrofloksasin dalam Mengatasi Coxiella burnetii
Abstrak: Coxiella burnetii belongs to rickettsia group living obligate intracellularly and as the agent of zoonosis Q fever. Enrofloxacine is an antibiotic in quinolon group used to treat infection of C. burnetii in chicken, goat, calve, pig, dog, cat, and horse. From ruminant practical experience, enrofloxacine if be combined with BioATP can enhance the enrofloxacine activity. Research for the effectivity of enrofloxacine and BioATP to treat C. burnetii has never been carried out. Enrofloxacine pharmacokinetic study was carried out by using simental beef as an experimental animals. The effectivity of BioATP supplementation on enrofloxacine activity to treat C. burnetii was tested by using Vero cell tissue culture. The results showed that combination of enrofloxacine and BioATP increased kinetic profile of enrofloxacine in term of onset, duration, pharmacology intensity, and bioavailaibility. Enrofloxacine had activity to treat C. burnetii with value of minimal inhibitory concentration (MIC) at 1-2 ppm and value of minimal bactericidal concentration at 4 ppm. Supplementation of BioATP improved the effectivity of enrofloxacine in treating C. burnetii.
