Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh pemberian jenis pakan yang berbeda terhadap pertumbuhan dan kelangsungan hidup benih ikan gurame (Osphronemus gouramy). Penelitian ini menggunakan metode eksperimen. Rancangan yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 3 ulangan. Hasil penelitian menunjukkan bahwa pertumbuhan mutlak panjang dan berat tertinggi ditunjukkan pada perlakuan B (F-888) berturut-turut sebesar 1.5 cm dan 1.3 g, disusul perlakuan A (F-999) berturut-turut sebesar 1.3 cm dan 1.1 g, disusul perlakuan C (IL 18 SP+1) berturut-turut sebesar 1 cm dan 0.8 g dan terendah pada perlakuan D (IL 28 K) berturut-turut sebesar 0.8 cm dan 0.6 g. Kelangsungan hidup benih ikan gurame selama penelitian menunjukkan perlakuan A sebesar 72.91% perlakuan B dan C sebesar 75% dan 68.75% sedangkan perlakuan D 77.08%. Hasil penelitian dilanjutkan dengan Uji Beda Nyata Terkecil (BNT) dengan tingkat kepercayaan 99%. This study aims to determine the effect of different types of feed on the growth and survival of gouramy seeds. This research is using experimental method. The design used was a completely randomized design (CRD) with 4 treatments and 3 replications. The results showed that the absolute highest growth in length and weight was shown in treatment B (F-888) respectively of 1.5 cm and 1.3 g, followed by treatment A (F-999) respectively of 1.3 cm and 1.1 g, followed by treatment C (IL 18 SP + 1) respectively of 1 cm and 0.8 g and the lowest in treatment D (IL 28 K) were 0.8 cm and 0.6 g, respectively. The survival of gouramy seeds during the study showed treatment A was 72.91% treatment B and C were 75% and 68.75% while treatment D was 77.08%. The results of the study continued with the Least Significant Difference Test (LSD) with a confidence level of 99%.

Abstract

Penelitian ini bertujuan untuk mengetahui umur simpan ikan julung-julung (Hemirhampus affinis) asap tumbuk halus pada kemasan polietilen dan kemasan semi aluminium foil. Ikan julung-julung asap kemudian ditumbuk halus dan dikemas dan disimpan pada suhu 25oC, 30oC dan 35oC. Laju perubahan kapang dihitung dengan menggunakan persamaan Arrhenius danpenentuan umur simpan ditentukan berdasarkan persamaan ordo nol. Umur simpan ikan julung-julung asap tumbuk halus pada kemasan polietilen lebih bertahan pada suhu ruang yaitu 37,6 hari. Sedangkan kemasan semi aluminium foil dapat lebih mempertahankan umur simpan pada suhu yang lebih tinggi dan pada suhu ruang hanya mampu bertahan hingga 42,43 hari. The aim of this study was to determine the shelf life of finely-ground-smoked finfish (Hemirhampus affinis) on polyethylene and semi-aluminum foil packagings. Smoked fish are then finely ground and packaged and stored at 25oC, 30oC and 35oC. The rate of change in molds is calculated using the Arrhenius equation and the shelf life is determined based on the zero order equation. The shelf life of finely-ground-smoked finfish in polyethylene packaging is better at room temperature is 37.6 days. While the semi-aluminum foil packaging can better maintain shelf life at higher temperatures and at room temperature can only last up to 42.43 days.

Keywords: shelf life; finfish; Hemirhampus affinis; finely-ground-smoked; polyethylene; semi-aluminum foil; packaging; mold.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh pemberian pakan buatan berbahan limbah kepala udang dengan dosis berbeda terhadap pertumbuhan dan sintasan benih ikan gurame (Osphronemus gouramy). Penelitian ini menggunakan metode eksperimen, dengan Rancangan Acak Lengkap (RAL) 4 perlakuan dan 3 ulangan. Hasil penelitian menunjukkan bahwa pertumbuhan panjang sebesar 0.17 cm dan pertambahan berat sebesar 0,12 gram pada semua perlakuan. Sintasan benih ikan gurame selama penelitian yaitu 65,42%. Hasil analisis sidik ragam panjang dan berat benih ikan gurame menunjukan bahwa dosis pakan yang berbeda tidak memberikan pengaruh nyata dengan nilai F Hitung panjang dan berat sebesar 0.3773 dan 0 sedangkan nilai F tabel (0,01) sebesar 7.59. This study aims to determine the effect of artificial feeding made from shrimp head (waste) at different dosages on the growth and survival of gouramy (Osphronemus gouramy) seeds. This study used an experimental method, with a Completely Randomized Design (CRD) of 4 treatments and 3 replications. The results showed that the growth of length is uniformly 0.17 cm and weight gain was 0.12 grams in all treatments. The survival rate of gouramy seeds during the study was 65.42%. The results of analysis of variance in length and weight of gouramy seeds showed that different dosages of feed did not have a real effect with F calculated value for length and weight of 0.3773 and 0, while the F table value (0.01) is 7.59. Katakunci: pakan buatan; pertumbuhan; sintasan; benih; gurami; Osphronemus gouramy. Keywords: artificial feed; growth; survivality; seed; gouramy; Osphronemus gouramy.
