Judul: Eutrophication of Two Sand Pit lake in Cikahuripan Village Cianjur
Abstrak: Sandpit lake is an artificial water bodies with small size filled with water because it has penetrated the underground water channels. As a new water body it has the potential to be exploited but without proper management, the usability of this sandpit lake can be short due to eutrophication process. The aims of this research were to describe eutrophication level and to analysis the trophic status of two sandpit lake in Cikahuripan Village wich is Situ no 5 and Situ no 6. The methodology of this research is descriptive analysis with sampling in Mei and July 2010. TRIX calculation results show the trophic status of both sandpit lake has been eutrofik that indicates eutrophication processes take place very quickly. This is supported by the parameters of physics, chemistry and biology both sandpit lake that characterized by high nutrients and productivity as well as the lack of brightness. Although there were observed that sandpit lake is still relatively new waters, but based on trophic status indicates eutrophication process has been going very quickly as a result of anthropogenic activities

Judul: Trophic States of Situ Patenggang, Bandung Regency, West Java
Abstrak: Situ Patenggang is managed as a recreation area in the form of Natural Tourism Park. Human activities around it can provide organic and inorganic materials which cause changes in lake’s trophic states. Utilization potential of water bodies can be measured by trophic state level that consider the presence of nutrients and phytoplankton. This study aims to determine the trophic states of Situ Patenggang, Bandung Regency, West Java. Sampling of water and phytoplankton were conducted at Situ Patenggang with four observation stations for three times of collections. Trophic index (TRIX) approach is used to analyzed the trophic state of Situ Patenggang. Concentration of total phosphate ranged from 0.20 – 0.64 mg/L. Dissolved inorganic nitrogen concentration ranged from 0.20 – 0.64 mg/L. Chlorophyll-a concentration ranged from 10.08 – 33.83 µg/L. Trophic states of Situ Patenggang is classified as eutrophic waters with values ranging from 4.25-6.54 according to the TRIX approach. These information can be used to anticipate trophic level increase for sustainable utilization of Situ Patenggang’s ecosystem., Situ Patenggang dikelola sebagai tempat rekreasi berupa Taman Wisata Alam Situ Patenggang. Aktivitas masyarakat di sekitar perairan dapat memberikan masukan bahan organik dan anorganik yang berpotensi meningkatkan kesuburan perairan. Tingkat kesuburan perairan erat kaitanya dengan potensi pemanfaatan perairan yang ditinjau dari keberadaan unsur hara dan kelimpahan fitoplankton. Penelitian ini bertujuan menentukan status kesuburan perairan Situ Patenggang, Kabupaten Bandung, Jawa Barat. Pengambilan contoh air dan fitoplankton dilakukan pada empat stasiun pengamatan selama tiga kali waktu pengambilan. Status kesuburan perairan dianalisis menggunakan pendekatan trophic index (TRIX). Konsentrasi fosfat total berkisar antara 0,04 – 0,19 mg/L. Konsentrasi nitrogen anorganik terlarut berkisar antara 0,20 – 0,64 mg/L. Konsentrasi klorofil-a berkisar antara 10,08 – 33,83 µg/L. Status kesuburan perairan Situ Patenggang berdasarkan pendekatan TRIX secara umum tergolong ke dalam perairan eutrofik dengan nilai berkisar antara 4,25 – 6,54. Hasil penelitian ini dapat digunakan sebagai informasi pendukung bagi pengelola dalam mengantisipasi terjadinya peningkatan status kesuburan perairan guna pemanfaatan perairan Situ Patenggang yang lebih optimal dan berkelanjutan.

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.
