Judul: Pemetaan  Sawah  Baku  Kabupaten  Subang  bagian  Barat dengan Citra Satelit ALOS.
Abstrak: Baseline rice field mapping is a mapping operation with wall to wall coverage characteristic, multi-purpose and cartographic base construction. This activity is suitable for tandem operation for routine updating of rural areal topographic map, in the rice production centre region to optimized cost. BIMAS- 21 is the first systematic method for baseline rice field mapping in Indonesia which adapt this approach. This research used ALOS PRISM and ALOS PALSAR imageries of Kabupaten Subang which ware recorded in 2007. Detailed analysis using ALOS PRISM was executed in Kecamatan Ciasem, and concentrated to the three villages: Desa Ciasembaru, Desa Ciasemtengah, and Desa Ciasemhilir. The processing of ALOS PRISM images were targeted to baseline rice field mapping, whereas the processing of ALOS PALSAR imageries were directed for plant growth monitoring, including rice phenology and planting progress acreage.

Judul: Analisis Penutupan Lahan Sawah Kecamatan Dramaga, Kabupaten Bogor, Propinsi Jawa Barat, dengan Citra Satelit Alos/Palsar
Abstrak: Pemetaan penutup lahan sawah di Kecamatan Dramaga, Kabupaten Bogor, Provinsi Jawa Barat merupakan upaya untuk menyajikan informasi luas produksi padi di area yang bukan menjadi pusat produksi padi. Hal ini disebabkan produksi padi di wilayah ini, tidak bisa dilepas peranannya dalam produksi padi untuk wilayah Pulau Jawa. Analisis polSAR diawali dengan mereduksi speckle pada citra polarisasi HH dan HV. Filter Lee berhasil mereduksi speckle, sehingga dihasilkan citra polarisasi terfilter Lee yang mampu menampilkan objek pembatas pada sawah (diperkirakan galangan sawah) secara jelas. Hasil analisis Digital Number (DN) pada citra polarisasi tersebut menunjukkan susunan citra RGB terbaik adalah citra polarisasi HH terfilter Lee, citra polarisasi HV terfilter Lee, dan citra sintetik masing-masing pada lapisan Red, Green, dan Blue. Pengamatan bentuk pola dan posisi distibusi grafik nilai intensitas piksel-piksel pada Horizontal Profile dari citra sintetik merupakan kunci menemukan citra sintetik HV/HH sebagai citra sintetik yang paling tepat untuk menghasilkan citra RGB terbaik tersebut. Sehingga citra RGB terbaik yang terpilih adalah citra RGB HH-HV-(HV/HH). Pengamatan nilai intensitas piksel dari citra RGB berhasil mengidentifikasi hamburan balik pada sawah 3 fase yaitu sawah fase awal tanam, sawah fase vegetatif, dan sawah fase generatif.

Judul: The Effects of Hypothyroidism in the Fertility of Male Rats
Abstrak: Thyroid hormones are involved in the development and maintenance of virtually all tissues. The purpose of the study is to understand effects of the neonatal hypothyroidism in the fertility of male rats. Recent studies with juvenile rats indicate that changes in thyroid function early in life have a major impact on the endocrine and/or paracrine factors regulating testicular growth and function. However, one should keep in mind that hypothyroidism is a complex hormonal dysfunction rather than a single hormonal defect. Hypothyroidism has been also shown to reduce the secretion of GnRH (gonadotropins releasing hormone), LH (Luteinizing Hormone), FSH (Follicle Stimulating Hormone), GH (Growth Hormone) and testicular testosterone in rats. Therefore, many of the testicular changes observed in prolonged hypothyroidism could result in some degree of diminished levels of the aforementioned hormones. The transient neonatal hypothyroidism model results in the unnatural testicular development and in sperm production in neonates hence resulting in decreased fertility upon puberty.
