Abstract

ABSTRACT: The present study aimed to determine the effect of different pH level on the density of Skeletonema costatum. A completely randomized design (CRD) consisting of four treatments with 4 replications, including pH 5, pH 6, pH 7 (Control), and pH 8 was applied. Skeletonema costatum density rate and water quality were measured for data collection. A One-Way ANOVA was performed for statiscal analysis and analyzed descriptively. The results showed that the highest Skeletonema costatum density was obtained at pH 8 (26,667 cells/ml), then pH 7 (13,333 cells/ml), pH 6 (11,000 cells/ml) and the lowest Skeletonema costatum density was found at pH 5 (10,000 cells/ml). Statistically, the pH had a significant effect on the density of Skeletonema costatum (p <0.05). this finding suggests that the optimal pH level for rearing was pH 8. ABSTRAK: Penelitian ini bertujuan untuk mengetahui pengaruh perbedaan pH terhadap kepadatan fitoplankton Skeletonema costatum. Metode yang digunakan Rancangan Acak Lengkap (RAL) yang terdiri dari empat perlakuan yaitu pH 5, pH 6, pH 7 (Kontrol), dan pH 8. Tiap perlakuan dilakukan tiga kali pengulangan sehingga diperoleh 12 unit percobaan. Parameter yang di uji meliputi laju Kepadatan Skeletonema costatum dan kualitas air. Analisis data menggunakan one way ANOVA untuk melihat signifikasi pengaruh perlakuan terhadap Kepadatan Skeletonema costatum dan hasil uji Kepadatan Skeletonema costatum di analisis secara deskriptif. Hasil penelitian ini memunjukkan kepadatan Skeletonema costatum tertinggi diperoleh pada pH 8 (26.667 sel/ml), kemudian pH 7 (13.333 sel/ml), pH 6 (11.000 sel/ml) dan Kepadatan Skeletonema costatum terendah pada pH 5 (10.000 sel/ml). Berdasarkan uji Anova, pH memberikan pengaruh nyata terhadap Kepadatan Skeletonema costatum (p<0,05) dengan perlakuan terbaik yakni pH 8.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh lama waktu pengkayaan HUFA (W-3 Highly Unsatured Fatty Acid) pada nauplius artemia terhadap perkembangan larva kepiting bakau (Scylla tranquebarica). Metode Penelitian ini didesain dengan menggunakan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan masing-masing 3 kali ulangan sehingga dibutuhkan wadah sebanyak 12 unit dengan perlakuan: A) Nauplius artemia diperkaya dengan HUFA selama 1 jam (Kontrol), B) Nauplius Artemia diperkaya dengan HUFA selama 3 jam, C) Nauplius artemia diperkaya dengan HUFA selama 6 jam D) Nauplius Artemia diperkaya dengan HUFA selama 9 jam. Hasil penelitian menunjukkan bahwa efek perbedaan lama waktu pengkayaan HUFA pada Nauplius artemia terhadap perkembangan larva kepiting bakau (Scylla tranquebarica) tidak berpengaruh nyata (P>0,05). Jumlah larva kepting bakau yang bertahan sangat sedikit pada perlakuan lama waktu pengkayaan HUFA pada nauplius artemia. ABSTRACT The present study aimed to determine the effect of the length of time enrichment of HUFA (W-3 Highly Unsaturated Fatty Acid) in Artemia nauplius on the development of mangrove crab (Scylla tranquebarica) larvae. A completely randomized design with 4 treatments with 3 replications were applied for experimental design, with the following treatments: (A) Nauplius artemia enriched with HUFA for 1 hour; (B) Nauplius Artemia enriched with HUFA for 3 hours; (C) Nauplius artemia was enriched with HUFA for 6 hours. (D) Nauplius Artemia was enriched with HUFA for 9 hours. The results indicated that the effect of differences in the length of time for HUFA enrichment in Nauplius artemia on the development of mud crab (Scylla tranquebarica) larvae showed no significant effect (P>0.05). Only a few mangrove crab larvae survived during treatment of HUFA enrichment time in Artemia nauplius.
