Judul: Analisis Kesetimbangan Air di Daerah Aliran Sungai Brantas, Jawa Timur
Abstrak: The principle of water balance is the relationship between total water inflow and water outflow that can occur in a watershed (DAS). The objectives of this study were to analyze the water balance based on capacity of ground water reservoir in the Brantas watershed and to solve deficit and surplus water problemes in the Brantas watershed. The result showed that groundwater storage in June until September was deficit because from June until September was the dry season periode. That is because the flow of water entering the soil layer will be the base flow (base flow), and the streams that will fill the river network system. The flow of water entering the river during the dry season in small quantities, so there is drought in the dry season. Efforts to do is to recharge wells made in order to increase the amount of water that entered and stored in the soil. Efforts to do is to recharge wells made in order to increase the amount of water that entered and stored in the soil.

Judul: Analysis of water balance and aridity index in catchment and irrigation area of Jatiluhur Reservoir
Abstrak: One of the functions of Jatiluhur Reservoir is to supply irrigation water for 264.000 ha of agricultural land in Pantura, West Java. Most of the farmlands in these area had water deficit during dry season. The purpose of this study were to analyze the water balance and aridity index in catchment and irrigation area of Jatiluhur reservoir, to calculate crop water requirements, irrigation water requirements and efficiency of irrigation channels on farms in the region Pantura West Java, and also to identify and mapping the areas that should receive high priority irrigation water supply. Water balance analysis using Thornthwaite- Mather method was done to obtain water resource potential representation of upstream Citarum watersheed, that hystorically had higher rainfall than its downstream. Irrigation water requirement was calculated by Penman – Monteith method of water balance analysis, using CropWat for Windows version 8.0 software. The result of rainfall analysis showed that dry season in Pantura was occured from April until November (eight months), and wet season was occured from December until March (four months). The result of water balance analysis showed that soils in this region experienced water deficit during April to December. Analysis of aridity index showed that the coastal region Pantura experienced severe drought from June to October, with August as the peak. Water balance of Citarum river and Jatiluhur reservoir indicated that irrigation water demand for agricultural land in Pantura could not fulfilled only by Citarum River, so it need subvention from local resource. Moreover, calculation using CropWat for Windows showed that water requirement for all agricultural land in Pantura was 3.797,7 million m3/year, while data from PJT II showed that the average of irrigation water supply for this area was 5.519,6 million m3/year. It indicated that efficiency of the irrigation Jatiluhur channels was about 68,8%.

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.
