Abstract

Abstract. The objective of present study was to evaluate the possibility of  papaya’s latex (Carica papaya) as anti stress or larvaside for tiger shrimp (Panaeus monodon) post larvae Pl 14-30 during transportation. The tiger shrimp post larvae was collected from BBAP Ujung Batee, Aceh Besar on September, 2012. Reseach method used the completely random design with two factors, density of post larvae with three treatments (1000; 1500 dan 2000 ind/l) and concentration of papaya’s latex with four treatments (0; 100; 200 dan 300 ppm) and three replications for each treatments. The effect of papaya’s latex on tiger shrimp post larvae was observed by calculating the percentage of post larvae’s survival rate. The calculation was only done after twelve hours of transportation, due to the everage of survival rate percentage of post larvae on all levels of density was less than 50%.  The ANOVA test showed that  the density and the concentration factors gave significance effect on survival rate of tiger shrimp post larvae (P0,05). The results showed that survival rate of tiger shrimp post larvae (PL 14-30) were decreased with increasing of larvae density and concentration of papaya’s latex.  However, Duncan’s test showed that the highest survival rate was obtained at 1.000 ind/l  and 0 ppm of papaya’s latex. Hence, the effect of papaya’s latex concentration treatments in this study was larvaside on tiger shrimp post larvae.Key words: Closed transportation system, dissolved oxygen, enzyme papain, tiger shrimp post larvae.

Abstract

The objective of this research was to determine the effect and the optimum concentration of Avicennia leaf extracts on prevalence, hatching rate and hatching time of common carp eggs (Cyprinus carpio) that infected by Saprolegnia sp. The research was conducted at Balai Benih Ikan (BBI) Lukup Badak, Aceh Tengah District in June 2016. The completely randomized design was used as statistical analysis method in this study with five treatments and 4 replications. The fertilized eggs of common carp were infected by Saporolegnia sp. then treated by immersing in the extract. The treatments were the different concentrations of extract, namely; 0, 5, 10, 15 and 20 ppm. The result of ANOVA test showed that the extract Avecenia leaf extracts gave the significant effect on the prevalence, hatching rate and hatching time of common carp eggs (P0.05). The best results for all parameters were recorded at the concentration of 10 ppm. Therefore, it is concluded that the optimum concentration is 10 ppm. Penelitian ini bertujuan untuk mengetahui pengaruh dan konsentrasi optimum ekstrak daun Avicennia marina terhadap prevalensi, daya tetas serta waktu tetas telur ikan mas (Cyprinus carpio) yang terinfeksi Saprolegnia sp. Penelitian dilakukan di Balai Benih Ikan (BBI) Lukup Badak, Kab. Aceh Tengah pada bulan Juni 2016. Analisis statistik menggunakan metode Rancangan Acak Lengkap (RAL) dengan 5 taraf perlakuan dan 4 kali ulangan. Sampel yang digunakan adalah telur ikan mas yang telah terbuahi dan terinfeksi dengan jamur Saprolegnia sp. kemudian direndam dengan ekstrak. Perlakuan yang dilakukan meliputi perlakuan konsentrasi ekstrak yaitu: 0, 5, 10, 15, 20 ppm. Hasil uji ANOVA menunjukkan bahwa ekstrak daun Avicennia marina berpengaruh nyata (P0,05) terhadap prevalensi serangan jamur, daya tetas serta waktu tetas telur ikan mas. Nilai terbaik untuk semua parameter yang diukur ditemukan pada konsentrasi 10 ppm ekstrak. Oleh karena itu disimpulkan bahwa konsentrasi yang optimum untuk telur ikan mas adalah 10 ppm.

Abstract

This study aimed to determine the optimal concentration of Moringa oleifera leaf extract as an antibacterial agent on Litopenaeus vannamei larvae that are infected by Vibrio sp.. It was conducted in 15 March - 15 April 2019 at PT. Global Gain Superior Seeds, Pantai Cermin, North Sumatera. The research used a completely randomized design (CRD) method with five treatments and four replications. The shrimps infected by Vibrio sp. were immersed into M. oleifera leaf extract in various concentration of (A) 0 ppm, (B) 400 ppm, (C) 600 ppm, (D) 800 ppm, and (E) 1000 ppm for ±15 minutes. The size of shrimp used was post-larvae 8 (length of 3.5-5 mm/ind). The best performance results of vannamei shrimps were obtained in treatment E (1000 ppm), namely length growth of 16.75 ± 1.16 cm, weight growth of 0.92 ± 0.89 g and survival rate of 91±7.87%.Keywords:Moringa oleiferaVibrio sp.Immersion

Abstract

Abstract. This study examined the selectivity of ethyl acetate extract of putat air (Barringtonia racemosa) in controlling Pomacea canaliculata compared to local catfish (Clarias batrachus). Five concentration of putat air (25, 50, 100, 200, and 400 ppm) with triplicate were tested in this study. The powder of putat air kernel was extracted through increasing the polarity of solvent, i.e. dichloromethane, ethyl acetate, and methanol. The mortality data were analyzed using Trimmed Spearman Karber (TSK) program version 1.5. The selectivity value was calculated based on LC50 values obtained from TSK. The results showed that (1) LC50 values of putat air's kernel extract of putat air to P. canaliculata and C. batrachus were 25.00 and 87.06 ppm, respectively, (2) the selectivity value of putat air's kernel extract as molluscicide of P. canaliculata was 3.48. Key words: Pomacea canaliculata, local catfish (Clarias batrachus), putat air (Barringtonia racemosa).

Abstract

Abstract. The objective of this research was to study the influence of salinity and buoyancy on hatchability of milkfish eggs (Chanos-chanos). The completely random design was used this study. Two factors i.e. salinity and buoyancy were tested where the salinity with three levels oncentration; 16, 23 and 30 ppt, while the buoyancy with three egg buoyancy categories i.e. floating, drifting and sinking with three replicates respectively. The result showed that the hatchability of floating eggs in tested salinities were 76,7% ; 78,75% ; 91,7%, for 16, 23 and 30 ppt, respectively. Then drifting eggs were 65,3%; 67,0%; 77,0% and sinking eggs were 54,0% ; 55,3% ; 65,0% for 16, 23 and 30 ppt, respectively. In generally, the hatchability was increased with increasing of salinity. In addition, the hatchability of the floating eggs was higher than the sinking eggs. Keyword: Salinity, buoyancy, hatchability, milkfish.
