Abstract

The consequence of super intensive shrimp farming is an increase in aquaculture waste and disease transmission. Vibrio sp. Bacteria is a disease-causing agent in shrimp larvae when the shrimp is in a state of stress and weakness, and can cause death. The application of probiotics, namely beneficial microorganisms can degrade organic matter, reduce disease, and help accelerate the process of nutrient cycles as a consequence of super intensive shrimp farming. Commercial probiotics currently available are a mixture of several types of beneficial microorganisms, namely Bacillus sp., Pseudomonas sp., Nitrosomonas sp., Aerobacter sp., and Nitrobacter sp. The purpose of this study was to evaluate the use of probiotics with different time intervals to produce a decrease in the population of Vibrio sp. The research method applied was the treatment of commercial probiotics at different intervals of three, five, and seven days and without the administration of probiotics as controls. Furthermore, the bacterial population was calculated by total plate count (TPC). The results showed that the administration of probiotics had a significant effect on the decrease in the population of Vibrio sp. Provision of probiotics three days apart showed a decrease in the number of bacterial populations that were significantly different from the controls, but the same as the administration of intervals of five and seven days. The decrease in the number of bacterial populations in the treatment interval of three, five, and seven days in a row is 0.05 x , 0.41 x , and 0.61 x  CFU / ml. This study recommends that the use of commercial probiotics intervals of seven days for super intensive vaname shrimp farming. The use of probiotics for three days indicates an impact on the increase in expenditure costs for probiotics. Commercial probiotic studies modified with natural microorganisms are thought to be able to streamline the operational costs of shrimp farming.Keywords: Vibrio sp. bacteria, probiotics, vaname shrimp, super intensive cultivation

Abstract

 Penelitian bertujuan untuk mengidentifikasi ektoparasit pada ikan mas koi (Cyrinus carpio) di Makassar. Penelitiandilakukan dengan pengambilan sampel sebanyak tiga kali di bulan April hingga Mei 2017. Sampel ikandimasukkan ke dalam kantong plastik yang telah diisi dengan oksigen. Jumlah sampel adalah 45 ikan denganpanjang 5,5-11,8 cm dan berat 5,12 – 13,2 g. Identifikasi parasit dan penghitungan jumlah parasit dilakukan diLaboratorium Parasit dan Penyakit Ikan, Departemen Perikanan, Fakultas Ilmu Kelautan dan PerikananUniversitas Hasanuddin. Data dianlaisis secara deskriptif. Serangan ektoparasit menyerang ikan koi di bagianinsang yakni 34,21%, sirip dorsal 34,21%, dan pada mukus mengandung 31,58%.Kata kunci : ektoparasit, identifikasi, ikan koi

Abstract

Penelitian ini bertujuan untuk menganalisis prevalensi serangan epifit Neosiphonia sp. pada rumput laut (Kappaphycus alvarezii) varietas coklat dan hijau. Penelitian ini dilaksanakan pada bulan Maret sampai dengan bulan April 2016 di Perairan Desa Punaga, Kecamatan Mangarabombang, Kabupaten Takalar. Tanaman uji yang digunakan adalah rumput laut jenis K. alvarezii varietas coklat dan hijau yang diperoleh dari Perairan Desa Punaga, Kecamatan Mangarabombang, Kabupaten Takalar. Rancangan penelitian yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan 2 perlakuan yaitu rumput laut varietas coklat dan hijau, dan 5 kali ulangan yaitu 5 kali pengamatan mulai pada awal tanam umur 1 hari, umur 10 hari, umur 20 hari, umur 30 hari dan umur 45 hari saat panen. Data hasil penelitian dianalisis dengan uji statistik non parametrik Chi-Square menggunakan SPSS 15. Hasil analisis statistik Chi-Square menunjukkan bahwa prevalensi serangan epifit Neosiphonia sp. pada rumput laut K. alvarezii varietas coklat dan hijau tidak terdapat perbedaan yang signifikan pada lima kali pengamatan.Kata kunci: Epifit Neosiphonia sp., prevalensi, rumput laut Kappaphycus alvarezii, varietas coklat dan hijau.
