Judul: Parameter Dinamika Populasi Ikan Cakalang (Katsuwonus pelamis Linnaeus, 1758) yang Didaratkan di PPS Cilacap, Provinsi Jawa Tengah.
Abstrak: Skipjack tuna (Katsuwonus pelamis) is a large pelagic fish that have important economic value in the Indian Ocean and also as a dominant fish landed in PPS Cilacap, Central Java. The aim of this research is to determine the population dynamics parameter of skipjack tuna in the Indian Ocean. This research was in December 2014 until March 2015. The data analysis conducted are sex ratios, gonad maturity, first lenght maturity, length frequency distribution and age, lenght and weight relationship, growth parameters, exploitation rate, and the surplus production model. The results shown growth of skipjack tuna move slow (K = 0,3). Lenght infinity (L∞) of skipjack tuna is 992,6303 mm, the exploitation rate is 0,93 and called as overexploited. Maximum sutainable yield (MSY) is about 3354,3 ton per year and optimum effort amount is 1700 trip per year. Management efforts to control fishing effort and restrictions of the fishing season.

Judul: Analisis Bioekonomi Sumber Daya Ikan Cakalang (Katsuwonus pelamis Linnaeus, 1758) di PPN Palabuhanratu, Provinsi Jawa Barat.
Abstrak: Bioeconomic analysis of skipjack tuna (Katsuwonus pelamis) was conducted to determine appropriate and sustainable fisheries resources management. This research was located in PPN Palabuhanratu, ProvinsiJawa Barat. In this research sampling was conducted four times during from December 2014 to March 2015. Data that was collected such as skipjack tuna’s length and weight, interview data, and statistical catch data of skipjack tuna. The aim of this research is to study skipjack tuna bioeconomic and sustainable yield. Exploitation rate with Ford Walford method is 0,6 per year. Surplus production model and bioconomic optimal effort of skipjack tuna is 317 trip per year with maximum sustainable yield 821 ton per year. Skipjack tuna fisheries resources utilization in this year can be estimated experience underfishing caused by some year before the utilization was overfishing. The appropriate policy that can be implied is limiting fish catch corresponding to Total Allowable Catch as big as 656 ton per year.

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.
