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: Prediksi Potensi Cadangan Airtanah Menggunakan Persamaan Darcy di Kota Tangerang Selatan, Provinsi Banten
Abstrak: Water is very important for human beings. Sources of freshwater that can be used is only 3% of the total water availability on earth. One of fresh water’s sources that can be used is groundwater. The objective of this study was to determine the capacity of groundwater storages (discharge) in aquifers at South Tangerang city using the Darcy equation. The method of research was include several stages, such as the preparation phase, data collection, data processing, data analysis, and presentation of results. Data were obtained from geoelectric measurements using Schlumberger software, and were used to analyse the type and depth of rock layers. Beside, the data were also used to determined the position of confined and unconfined aquifer. The flownet of confined and unconfined aquifer indicated the scheme of groundwater’s flow and was used to decide the cross section of the flow. Darcy equation required another parameter called hydraulic conductivity. In this research, the aquifer was dominated by sand, so the hydraulic conductivity for sand (12 m/day) was used in calculation. As the result groundwater storages on unconfined aquifer was 3551,50 m3/day, while on confined aquifer was 16864.11 m3/day.

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.
