Judul: Effectiveness of Eel Seed (Glass Eel) Fishing Gears at the Cimandiri River Sukabumi Estuary
Abstrak: Currently, eel seed farming still depends on the availability of natural catches of the glass eel. The Cimandiri river estuary is one of the potential glass eel fishing grounds in the Sukabumi Regency. This study aims to estimate the effectiveness of glass eel fishing gear at the Cimandiri River Estuary bycatch and measure water parameters at the research site. Field surveys and laboratory measurements were carried out for this study. The data were analyzed using descriptive, productivity, and effectiveness of the fishing gears (lift nets and push nets) and the analysis of the main target and bycatch of the gears. This study showed that water temperature, salinity, and pH in the Cimandiri River Estuary were suitable for the glass eel: a temperature of 28-30 C, a salinity of 0-4 PSU, and pH of about 6-7. The productivity value of the lift net was 33.22 g/hour, while the push net was 46.03 g/hour. The catches consisted of 92.58% main catch and 7.42% bycatch. The effectiveness value of the lift net was 91.76% for the main catch and 8.24% for the bycatch, while the pus net was 93.40% for the main catch and 6.60% for the bycatch. Thus, one could conclude that the fishing gears of the push net are more effective than the lift net to catch the glass eels.

Judul: Water Quality of Glass Eel Habitat (Anguilla spp.) at the  Cikaso River Estuary, Sukabumi West Java
Abstrak: Kondisi kualitas air menjadi sangat penting dalam menopang kelimpahan glass eel di muara Sungai Cikaso. Penelitian ini bertujuan untuk menganalisis kualitas air habitat dan kondisi biologis glass eel di muara Sungai Cikaso, Sukabumi, Jawa Barat. Pengambilan sampel dilakukan di muara Sungai Cikaso, Jawa Barat dalam kurun waktu Februari hingga Juni 2021. Penelitian ini menggunakan metode Principal Component Analysis dan Water Quality Index untuk menjelaskan karakteristik habitat glass eel. Glass eel yang tertangkap terdiri atas tiga jenis yakni Anguilla bicolor bicolor, Anguilla nebulosa, dan Anguilla marmorata. Anguilla bicolor bicolor merupakan jenis glass eel yang paling banyak tertangkap. Glass eel memiliki panjang total berkisar 43-73 mm. Glass eel yang ditangkap memiliki pola pertumbuhan alometrik negative dengan nilai faktor kondisi sebesar 0,7624-1,0302. Estimasi populasi glass eel yang diperoleh secara keseluruhan sebanyak 13.348.267 individu dan biomassa 1685,46 kg. Nilai WQI yang didapatkan termasuk kategori sangat baik dengan nilai sebesar 91. Kualitas air habitat muara Sungai Cikaso sangat mendukung kehidupan glass eel berdasarkan nilai Water Quality Index dan kondisi biologis glass eel., Water quality conditions become very important in sustaining the abundance of glass eels at the Cikaso River estuary. This study aimed to analyze the water quality of habitats and biological conditions of glass eels at the Cikaso River estuary, Sukabumi, West Java. Sampling was conducted at the Cikaso River estuary, West Java in the period February to June 2021. The study used the Principal Component Analysis and Water Quality Index methods to explain the characteristics of glass eel habitats. Glass eels are caught consisting of three species include Anguilla bicolor bicolor, Anguilla nebulosa, and Anguilla marmorata. Anguilla bicolor bicolor is the most common type of glass eel caught. Glass eels have a total length ranging from 43-73 mm. The captured glass eel has a negative alometric growth pattern with a condition factor value of 0.7624-1.0302. The estimated population of glass eels obtained as a whole is 13,348,267 individuals and biomass of 1685.46 kg. The WQI value obtained belongs to the category was very good with a value of 91. Water quality of the Cikaso River estuary habitat strongly supports glass eel life based on water quality index values and biological conditions of glass eels.

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.
