Penelitian ini bertujuan untuk mengetahui apakah ada perbedaan rata-rata durasi molting lobster dengan pemberian pakan tanpa Dicalsium Phosphate (DCP) dibandingkan dengan pakan yang diberi tambahan Dicalsium Phosphate (DCP). Penelitian dilaksanakan pada bulan Januari - Februari selama 40 hari di CV. Cova Akuakultur. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan dua perlakuan dan 5 kali ulangan, yaitu A (pakan pellet kontrol), B (penambahan dicalsium phosphate 4%). Parameter yang diiuji adalah durasi molting lobster air tawar. Kualitas air meliputi suhu, pH, dan DO. Analisis data menggunakan Independent Sample T Test dengan tingkat kepercayaan 95%, menunjukkan bahwa perlakuan pemberian pakan tanpa Dicalsium Phosphate (DCP) dibandingkan dengan pakan yang diberi tambahan Dicalsium Phosphate (DCP) berbeda (P>0,05). Suplementasi dicalsium phosphate pada pakan berpengaruh terhadap durasi molting lobster air tawar Cherax quadricarinatus.
The objective of this study is to ascertain whether there is a discrepancy in the mean duration of lobster molting when fed a diet devoid of Dicalsium Phosphate (DCP) as opposed to a diet fortified with Dicalsium Phosphate (DCP). The research was conducted over the course of 40 days in January and February at CV. Cova Aquaculture. The present study employed a completely randomized design (CRD), encompassing two distinct treatments and five replicates. Treatment A (corresponded to the control feed) and B (involved the incorporation of 4% dicalsium phosphate). The parameter that was subjected to testing was the duration of crayfish molting. The quality of water is determined by various parameters, including temperature, pH level, and dissolved oxygen (DO) concentration. The application of an independent sample t-test with a 95% confidence level revealed that the treatment involving the absence of dicalsium phosphate (DCP) in feed, in comparison to the presence of DCP in feed, exhibited a discrepancy (P > 0.05). The impact of dicalsium phosphate supplementation in feed on the duration of molting in crayfish Cherax quadricarinatus has been a subject of considerable interest.
