Judul: Penentuan Sebaran Akuifer Dengan Metode Tahanan Jenis (Resistivity Method) Di Kota Tangerang Selatan, Provinsi Banten
Abstrak: Water is a basic requirement for humans being. The population growth can result a higher water demand. Surface water quality is declining due to human activities that make the usage of groundwater increased. The excessive exploration of groundwater can result soil subsidence, it is necessary to study the characteristics of groundwater. This study aimed to identify the lithology of soil, the position and thickness of aquifer, and to analyze aquifer distribution at the research area. The resistivity method was used to to identivity the lithology of soil. Analysis results showed that the depth of unconfined aquifer at the research area was 3,00-44,73 m below soil surface with a thickness of 2-12 m. Litology of soil was a clay and tufaan sand. The depth of confined aquifer was 80-130 m below soil surface with a thickness of more than 75 m. Groundwater flow patterns at the research location headed toward the north.

Judul: Sebaran TDS, DHL, Penurunan Muka Airtanah dan Prediksi Intrusi Air Laut di Kota Tangerang Selatan
Abstrak: The overuse of groundwater with the management of water sources that ignores the environment can decrease the quantity and quality of groundwater. In the area of South Tangerang City, groundwater quality degradation is caused by the dynamics of development South Tangerang City towards the profile of Metropolitan City. The purpose of this research is to make the water quality zone map based on DHL and TDS parameter, zone map based on decrease of groundwater level and predict the occurrence of seawater intrusion in the South Tangerang City. The research method used is to identify the quality groundwater and a decrease of groundwater level from water analysis using Kepmen ESDM Nomor 1451.K/10/MEM/2000 and make the distribution of water quality and a decrease of groundwater level using the software Surfer 9 and ArcView GIS 3.2, and predict patterns spread of seawater intrusion from water quality analysis using the regression equation. From the identification result and analysis of water quality, South Tangerang City is categorized as a safe zone. Safe zone is the area that meets one of decrease criteria on groundwater quality which are characterized by the increase of TDS that is less than 1,000 mg/l or less than 1,000 DHL μmhos/cm.

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.
