Abstract

AbstrakPenelitian ini bertujuan untuk mengetahui tingkat pertumbuhan ikan bawal yang diberi perlakuan cahaya pada malam hari. Metode yang digunakan pada penelitian ini adalah metode eksperimental dengan 4 perlakuan dan 3 ulangan. Pada setiap perlakuan dengan waktu pencahayaan selama P1=12 jam, P2=16 jam, P3=20 jam, dan P4=24 jam. Hasil dari perlakuan tersebut berpengaruh nyata terhadap laju pertumbuhan, bobot mutlak, panjang mutlak, dan rasio konversi pakan (FCR). Sedangkan pada sintasan tidak memiliki perbedaan yang signifikan. Laju pertumbuhan harian tertinggi terdapat pada P4 sebesar 5,30%, sedangkan laju pertumbuhan yang terendah terdapat pada P1 sebesar 4,47%. Berat mutlak tertinggi didapat pada P4 sebesar 25,40 gr, sedangkan berat mutlak terendah pada P1 sebesar 17,91 gr. Selanjutnya pada parameter panjang mutlak yang tertinggi juga pada P4 sebesar 4,66 cm, sedangkan yang terendah pada perlakuan P1 sebesar 3,66 cm. Pada rasio konversi pakan memiliki nilai tertinggi pada P1 sebesar 1,69±0,02  dan  terendah pada P2 sebesar 1,45±0,12. Dari hasil perekayasaan dengan waktu pencahayaan pada lingkungan budidaya, semakin lama waktu pencahayaan yang diberikan maka pertumbuhan yang dihasilkan memiliki kategori semakin baik.Kata kunci: ikan bawal; lampu pijar; pertumbuhan; rekayasa cahayaAbstractThis study aims to determine the growth rate of pomfret, which is treated with light at night. The method used in this study is an experimental method with 4 treatments and 3 replications. At each treatment with lighting times for P1 = 12 hours, P2 = 16 hours, P3 = 20 hours, and P4 = 24 hours. The results of these treatments significantly influence the growth rate, absolute weight, absolute length, and feed conversion ratio (FCR), whereas the survival does not have a significant difference. The highest daily growth rate is in P4 of 5.30%, while the lowest growth rate is at P1 of 4.47%. The highest total weight in P4 of 25,40 gr, while the lowest total weight at P1 is 17.91 gr. Furthermore, the highest absolute parameter is P4 of 4.66 cm, while the lowest in the first step is 3.66 cm. The feed conversion ratio has the highest value at P1 at 1.69 ± 0.02 and the lowest at P2 at 1.45 ± 0.12. From the results of engineering with the lighting time in the aquaculture environment, the longer the lighting time is given, the better the resulting growth has been.Keywords: pomfret; incandescent bulbs; growth; light modification

Abstract

The recirculation system in the maintenance of tortoise will affect several water quality parameters, also known as water quality dynamics. Water quality such as temperature, DO, pH, turbidity, nitrate, nitrite, alkalinity, total hardness, TAN are parameters that are directly related to the physiological system of fish. The purpose of this study was to see the effect of various recirculation systems on water quality dynamics. This study used an experimental method with a completely randomized design (CRD) consisting of 4 treatments and 3 replications and fish were kept for 20 days. The results obtained during the research include physical and chemical parameters. The temperature was between 24.5Co-27.6Co, the highest temperature measured in the current recirculation system treatment, the degree of acidity (pH) the average pH value ranged from 6.10-7.42. The value of nitrite ranged from 0.041-0.083 mg/L. Nitrate values ranged on average from 4.40 to 5.32. The average alkalinity value ranges from 44.02 to 77.30 alkalinity has a large effect on pH. Ammonia is produced from the excretory activity of fish, the average value of ammonia is 0.05 - 0.2 mg/L. In this study, the highest survival rate was found in the current recirculation treatment with a survival rate of 99%, and the lowest survival value was found in the non-recirculating treatment with a value of 53.5%. In this study, water quality is very influential on the survival of the jungle fish.Keywords: water quality; jurung fish; maintenance; recirculation; Dynamics system

Abstract

In Aceh Province, tiger prawns (Penaeus monodon) are one of the main commodities of farmers for cultivation. Feed is one of the factors that can support the development of tiger prawn culture. The quality feed is feed that contains essential nutrients in sufficient quantities, one of which is protein. This study aims to determine the effect of commercial feed with different protein content on the growth and survival of tiger prawn fry. This study used a completely randomized design (CRD) method consisting of 3 treatments and 4 repetitions, namely P1 (using 40% protein feed), P2 (using 35% protein feed), and P3 (using 26% protein feed). The results showed that commercial feed with different protein content had an effect on active weight growth and feed conversion ratio, but had no effect on tiger prawn survival. Furthermore, the best protein content for the growth and survival of tiger prawn was obtained, namely 40%.Keywords: commercial feed; growth; protein; survival rate; tiger prawn.

Abstract

The male Betta fish is said to be special because it has a unique body shape and beautiful colours, so it is very popular among people who love ornamental fish. This research aims to analyze the effectiveness of giving goat testicle flour on sex reversal in betta fish. The research design carried out was a Completely Randomized Design (CRD). consisting of 4 treatments with 3 repetitions. During the 60-day rearing period, silkworms and artemia were given food. The results of the study showed that the effect on goat testicles had a significant effect on the male sex ratio and survival of betta fish, with a male sex ratio value of 74.92% and survival of 97.77%. Water quality during the research supports the male sex ratio and the survival of betta fish.Keywords: Betta Fish; Goat Testicular Meal; Male Sex Ratio, Sex Reversal; Survival
