Abstract

ABSTRAKPertumbuhan post larva udang vaname (Litopenaeus vannamei) sangat dipengaruhi oleh kualitas pakan, salah satunya kadar protein. Kekurangan kadar protein dapat menghambat pertumbuhan. Sebaliknya, jika berlebihan dapat meningkatkan energi untuk katabolisme protein yang salah satu hasilnya berupa nitrogen yang akan dikeluarkan dalam bentuk amoniak melalui ginjal. Penelitian ini bertujuan untuk mengetahui kadar protein pakan yang optimal terhadap pertumbuhan berat mutlak udang vaname umur PL8-PL21 di bak-bak percobaan. Penelitian ini menggunakan metode eksperimental dengan 5 perlakuan dan 5 perulangan. Lima perlakuan tersebut, yaitu perlakuan A ; pakan komersial berkadar protein 25%, B ; pakan komersial berkadar protein 30%, C ; pakan komersial beradar protein 35%, D ; pakan komersial berkadar protein 40%, dan E ; pakan komersial berkadar protein 45%. Hewan ujinya berupa udang vaname (Litopenaeus vannamei) umur PL8dengan berat rata-rata 0.0012 gr/ekor. Jumlah padat tebar 1 ekor/liter. Hasil penelitian menunjukkan perlakuan C menghasilkan pertumbuhan tertinggi dengan rata-rata 0.073 gr/ekor. Data kualitas air diperoleh suhu air berkisar 27,40-27,42oC, derajat keasaman 7,71-7,72 dan oksigen terlarut bekisar 6,18-6,19 ppm.Kata Kunci: kadar protein, pakan komersial, pertumbuhan berat mutlak, udang vaname (Litopenaeus vannamei) umur PL8-PL21.ABSTRACTThe growth of vannamei shrimp (Litopenaeus vannamei) postlarvae is significantly influenced by the quality of the feed, one of which is protein content. A deficiency in protein levels can inhibit growth. Conversely, if excessive can increase energy for protein catabolism, one of the results is in the form of nitrogen which will be excreted in the form of ammonia through the kidneys. This study aims to determine the optimal feed protein content for absolute weight growth of PL8-PL21 vannamei shrimp in experimental tub. This study used an experimental method with 5 treatments and 5 repetitions. The five treatments, namely treatment A ; commercial feed with 25% protein, B ; commercial feed with 30% protein, C ; commercial feed containing 35% protein, D ; commercial feed with 40% protein, and E ; commercial feed with 45% protein content. The test animals were vannamei shrimp (Litopenaeus vannamei) PL8 age with an average weight of 0.0012 g/head. Total stocking density of 1 head/litre. The results showed that treatment C produced the highest growth with an average of 0.073 g/head. Water quality data obtained water temperature ranged from 27.40-27.42oC, acidity degree 7.71-7.72, and dissolved oxygen ranged from 6.18-6.19 ppm.Key words: protein content, commercial feed, absolute weight growth, vaname shrimp (Litopenaeus vannamei) PL8-PL21 age

Abstract

ABSTRAKIkan maskoki termasuk ikan hias dengan banyak penggemar karena strain yang beragam. Jenis parasit yang sering menyerang ikan air tawar adalah Trichodina sp. Dactylogyrus sp. Gyrodactylus sp. Ichtyopthirius mulrifilis sp. Lernaea sp. Argulus sp. dan Myxobolus sp. Kelebihan biji pepaya sebagai obat adalah tidak menimbulkan efek samping, mudah didapat dan harga terjangkau. Pemanfaatan biji pepaya yaitu dengan membuat perasan biji pepaya karena mudah, murah dan cepat. Biji pepaya mengandung alkaloid karpain yang bersifat sebagai insektisida nabati. Perlakuan yang digunakan dalam penelitian ini dimana Argulus yang menempel dengan persentase paling sedikit dan ikan dapat bertahan hidup dengan metode dipping perasan biji papaya. Metode pengambilan data yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap (RAL) dengan 4 perlakuan : A Media uji tanpa perasan biji papaya konsentrasi 0 ml/l air, B Media uji dengan perasan biji pepaya konsentrasi 20 ml/l air, C Media uji dengan perasan biji pepaya konsentrasi 40 ml/l air, D Media uji dengan perasan biji pepaya konsentrasi 60 ml/l air. Perlakuan D dosis yang paling baik diantara perlakuan lainnya karena karpain bekerja menekan sistem saraf pusat. Karpain memiliki aktivitas menekan Central Nervous system dengan mengikat ion Na+ pada saraf. Ion Na+ berfungsi mengantarkan impuls saraf hingga terjadi aksi. Saraf Argulus berhubungan dengan sucker yang berfungsi untuk menempel. Saraf yang ditekan tidak dapat mengantar impuls saraf sampai ke sucker mengakibatkan Argulus tidak dapat menginfestasi ikan maskoki. Perasan biji papaya dengan konsentrasi berbeda berpengaruh sangat nyata terhadap parasit Argulus, Pemeberian 60 ml/l (perlakuan D) dapat menekan Argulus yang sangat tinggi yaitu 30,56%, Pemeberian 40 ml/l (perlakuan C) dapat menekan Argulus yaitu 25% Pemeberian 20 ml/l (perlakuan B) dapat menekan Argulus yaitu 11,11% Pemeberian 0 ml (perlakuan A) tidak dapat menekan pertumbuhan Argulus atau sama halnya 0%.Kata kunci: Perasan Biji Pepaya, Obat Herbal, Parasit Argulus indicus, Ikan Maskoki Carassius auratusABSRACTGoldfish are ornamental fish with many fans because of their diverse strains. The type of parasite that often attacks freshwater fish is Trichodina sp. Dactylogyrus sp. Gyrodactylus sp. Ichtyopthirius mulrifilis sp. Lernaea sp. Argulus sp. and Myxobolus sp. The advantages of papaya seeds as medicine are that they do not cause side effects, are easy to obtain and are affordable. The use of papaya seeds is by making papaya seed juice because it is easy, cheap and fast. Papaya seeds contain carpain alkaloids which act as a botanical insecticide. The treatment used in this research was that Argulus was attached in the smallest percentage and the fish could survive using the papaya seed juice dipping method. The data collection method used in this research was a Completely Randomized Design (CRD) with 4 treatments: A Test media without papaya seed juice with a concentration of 0 ml/l water, B Test media with papaya seed juice with a concentration of 20 ml/l water, C Test media with papaya seed juice with a concentration of 40 ml/l water, D Test media with papaya seed juice with a concentration of 60 ml/l water. Treatment D is the best dose among other treatments because carpain works to suppress the central nervous system. Karpain has the activity of suppressing the Central Nervous system by binding Na+ ions to the nerves. Na+ ions function to deliver nerve impulses until action occurs. The Argulus nerve is connected to the sucker which functions to attach. The compressed nerve cannot transmit nerve impulses to the sucker, resulting in Argulus being unable to infest the goldfish. Papaya seed juice with different concentrations has a very significant effect on Argulus parasites. Giving 60 ml/l (treatment D) can suppress Argulus which is very high, namely 30.56%, giving 40 ml/l (treatment C) can suppress Argulus, namely 25%. 20 ml/l (treatment B) can suppress Argulus, namely 11.11%. Giving 0 ml (treatment A) cannot suppress the growth of Argulus or the same as 0%.Keywords: Papaya Seed Juice, Herbal Medicine, Argulus indicus Parasite, Goldfish Carassius auratus
