Judul: Peran pembayaran jasa lingkungan (PJL) hutan terhadap sifat hidrologi lahan di DAS Cidanau, Banten
Abstrak: Payment for Environmental Services (PES) in Cidanau watershed is the payment for environmental services of Forest Ecosystem to control the water yield in Cidanau watershed. This PES is driven by issue of water yield decreasing, suggested due to forest encroachment of Rawa Danau. The role of PES for water yield control is approached through its role for the soil hydraulic properties. The research aim to analyze the difference of soil hydraulic properties managed with and without PES incentives. The research includes analysis of land use changes, infiltration rate and soil hydraulic properties of land with and without PES, and simulation of water flow as the response of rainfall. Implementation of PES in Cidanau watershed is able to maintain the good condition of forest. Soil hydraulic properties of land with PES is relatively better. The infiltration rate of land with PES is higher than without PES. Gravitational and available water is higher in land of without PES whereas the soil hydraulic condactivity is higher in land of with PES. Kostiakov and Horton models both are able to predict the rate of infiltration. Kostiakov is better than Horton model relatively. Log Normal Kosugi model was able to predict a soil-water retension curve and unsaturated hydraulic conductivity. One dimensional vertical flow simulation shown the higher flow in land with PES than without PES.

Judul: Dampak Pembayaran Jasa Lingkungan Daerah Aliran Sungai Cidanau Terhadap Sosial Ekonomi Masyarakat Desa Citaman, Serang
Abstrak: Payment for environmental services (PES) is a social institution that organizes the relationship between Citaman Village’s farmers as a provider of environmental services, and PT. KTI as the payer of environmental services.The objectives of this study are to analyze the impact of PES on the socio-economic conditions of the Citaman’s farmers, and to analyze benefits that received by the payer of environmental service i.e. PT KTI. The results show that, first, PES creates positive impact to the socio-economic conditions ofCitaman’s farmers, such aspositive engagement of the farmers community to the PJL scheme, active participation of the Forest’s Farmer Group, increase farmer incomes, creates newlivelihood formations,as well asincentives received by the farmers. Second, so far, from the ecological point of view, PES has not able to provide benefits for payer of the environmental servicse, particularly seeing from the water continuation and fluctuation. However, it is expected that the payer could gained the ecological benefits of PES if the schemecould work in a more longer and vast area than present.

Judul: Infeksin virus rota pada anak babi
Abstrak: Virus Rota sudah lama diduga sebagai salah satu penyebab diare pada anak babi yang baru dilahirkan. Hal ini diperkuat dengan berhasilnya Mebus dan kawan-kawan mengidentifikasi virus Rota pada kejadian diare yang ter jadi pada anak sapi yang baru dilahirkan. Infeksi virus Rota merupakan hal yang serius, kejadian yang mewabah pernah dilaporkan di Amerika Serikat, Inggris, Kanada dan Australia. Sedangkan kejadian di Indonesia yang dihubungkan dengan infeksi virus Rota belum dilaporkan. Virus Rota termasuk keluarga Reo viridea. Sesuai dengan namanya, virus Rota menyerupai roda (Rota = Wheel), mengandung asam nukleat (nucleid acid) yang berupa asam nukleat ribo (ribo nucleid acid, RNA) dan berserabut ganda (double stranded), tidak mempunyai selubung (envelop atau peplos). Hewan rentan adalah hewan yang berumur sangat muda. Selain menyerang babi, dapat pula menyerang sapi, domba, rusa, anjing, kucing, tikus, kelinci, unggas dan manusia. ...
