Judul: Model skema pembayaran jasa lingkungan dalam pengelolaan daerah aliran sungai (studi kasus di sub DAS Citanduy Hulu dan sub DAS Ciseel)
Abstrak: This study suggests an alternative solution to solve degradation in Subwatershed Citanduy Hulu and Sub-watershed Ciseel using Payment Environmental Services (PES) model. It is an instrument of economic policy based on economic incentives. PES is established between the owner or manager of the land on the upstream with water users both for commercial and non commercial purposes on the middle as well as the downstream. Conditions and characteristics of the watershed are different from one to another, therefore in order to apply PES an appropriate model is required. The purpose of this study is to design a PES model in Sub-watershed Citanduy Hulu and Sub-watershed Ciseel, includes an analysis of the typology of the watershed, watershed characteristics analysis, economic valuation and institutional analysis. The typology of watershed is used to determine which regions are eligible for the implementation of PES. Soil Water Assessment Tool (SWAT) is applied to determine such regions. The analysis showed that there are 7 (seven) Subwatershed in the area of Citanduy watershed, namely: Sub-watershed Citanduy Hulu, Cijolang, Cimuntur, Ciseel, Cikawung, Citanduy Tengah and Citanduy Hilir. Among those sub-watersheds, only Sub-watershed Citanduy Hulu and Subwatershed Ciseel are qualified because of their potential for environmental services, environmental service providers, resource management, and institutional environment. The watershed characteristics is used as the basis for determining the scope of the PES model. From SWAT analysis results in flow of water in the upstream Sub-watershed Citanduy Hulu, which is about 11,4% is the flow of surface (surface flow) and 88.6% lateral and groundwater flow, while in the middle-end of about 5,5% is the surface flow and 94,5% lateral and ground water flow. This condition shows that from the aspect of availability of Sub-watershed Citanduy Hulu currently still in safe condition, both the dry and rainy season. Nevertheless, in order of quantity, quality and continuity of water can remain assured, it is need to rehabilitate the land cover with the erosion rate is relatively moderate and severe area of 1.574 Ha and maintain existing wetland and gardens. For Sub-watershed Ciseel water flow composition in the upper and middledownstream almost equal, is about 46% came from surface flow and 54% of the lateral and groundwater flow. This condition shows that from the aspect of availability of Sub-watershed Ciseel still depends on the season, it is necessary to rehabilitation and conservation of land cover with moderate and severe area of 1.402 Ha and improve wetland and gardens conditions. This indicates that the water catchment area in each unit of land significant role in providing groundwater recharge...dst

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: Infeksi Virus Parainfluenza Pada Anjing
Abstrak: Virus parainfluenza anjing termasuk famili Paramyxoviridae, berbentuk pleomorf dengan ukuran bervariasi (bergaris tengah antara 100-500 nm), berpembungkus peka ether, berisi genom RNA dan secara serologis mempunyai kesamaan dengan virus SV-5 kera; dikenak sebagai salah satu kausa penting dari sindrom "kennel cough". Infeksinya dapat mengenai anjing semua umur yang belum pernah terinfeksi atau mendapatkan vaksinasi mengakibatkan gejala klinis ringan yang terbatas pada traktus respirasi atu infeksi yang secara klinis tidak memperlihatkan gejala nyata. Gejala klinis yang nampak setelah masa inkubasi (1-5 hari) terlewati berupa batuk yang tidak berat selama beberapa hari, berbagai tingkat tonsilitis dan pharyngitis dan kadang-kadang ditemukan kenaikan temperatur rektal antara 1-2 derajat C dari temperatur normal rat-rata. Anjing terinfeksi mengandung virus pada traktus respirasi bagian atas dan bawah serta limfonoduli sampai hari ke 9 setelah infeksi. Penyebaran virus antar anjing terjadi secara aerogen.
