Abstract

Pemberian ekstrak pepaya dan ekstrak nanas pada pakan buatan lobster air tawar (Cherax quadricarinatus) diharapkan dapat meningkatkan pemanfaatan protein pakan dan pertumbuhan lobster air tawar.  Penelitian ini bertujuan untuk mengkaji pengaruh penambahan ekstrak pepaya dan nanas terhadap tingkat pemanfaatan protein pakan serta keterkaitan dengan nilai efisiensi pemanfaatan pakan, protein efisiensi rasio, laju pertumbuhan relatif, dan kelulushidupan.  Serta mengetahui dosis terbaik dari penambahan kombinasi ekstrak pepaya dan ekstrak nanas terhadap pertumbuhan lobster air tawar.  Lobster uji yang digunakan adalah dengan ukuran 1,5-2 cm dengan kepadatan 100 lobster/m3.  Frekuensi pemberian pakan masing-masing 2 kali sehari, menggunakan metode at satiation.  Penelitian ini menggunakan rancangan acak lengkap dengan 5 perlakuan dan 3 ulangan yaitu pakan buatan dengan penambahan ekstrak pepaya dan nanas dengan perbandingan sebesar 100:0; 75:25; 50:50; 25:75; 0:100% untuk perlakuan A, B, C, D dan E.  Hasil penelitian menunjukan bahwa perlakuan dengan menggunakan perbandingan 50:50% treatment C memberikan pengaruh tertinggi (P<0,05) terhadap nilai EPP, PER dan RGR yaitu masing-masing sebesar EPP 45,91±4,86, PER 1,15±0,12 dan RGR 0,79±0,06 dan kelulushidupan (SR) memberikan pengaruh yang sama (P>0,05) yaitu SR 95,83%.  Berdasarkan hasil penelitian dapat disimpulkan bahwa ekstrak pepaya dan nanas dengan perbandingan yang sama dalam pakan mampu meningkatkan nilai EPP, PER dan RGR pada lobster air tawar.  Papaya and pineapple extracts on the artificial diets freshwater lobster (Cherax quadricarinatus) were expected to be able to improve the dietary protein utilization and growth of lobster.  This study aimed to determine the effects of various combinations of the papaya and pineapple exstracts to utilization of dietary protein, growth, and survivors of the lobster.  Determine the best dose of the addition of a combination of papaya and pineapple extracts on the growth of lobster.  The trial lobster used was 1,5-2 cm with its density of 100 lobster/m3.  The feed frequency applied was 2 times a day and was at satiation method.  This study used a completely randomized design with 5 treatments and 3 replicates.  They were practical diets with the ratio of papaya and pineapple extracts addition in the diet 100:0; 75:25; 50:50; 25:75; 0:100% for treatment A, B, C, D and E respectively.  The data showed that the trial diet with ratio of 50:50%, that was treatment C, resulted on the highest effect (P<0,05) on the values of EPP (e.g. 45,91±4,86), PER (e.g. 1,15±0,12) and RGR (e.g. 0,79±0,06). Survival rate (SR) resulted on similar effect (P>0,05), that were SR 95,83%.  It was concluded that the addition of extract papaya and pineapple with similar ratio onto feed increased the values of EPP, PER and RGR of the freshwater lobster.

Abstract

Kenaikan produksi budidaya di Indonesia diupayakan dengan memanfaatkan lahan secara optimal. Budidaya sistem tertutup akan memproduksi limbah dari hasil metabolisme yang secara berkelanjutan mencapai level yang beracun bagi ikan. Salah satu upaya untuk menanggulangi masalah tersebut yaitu pengelolaan lingkungan budidaya dengan sistem biofilter akuaponik. Tujuan dari penelitian ini adalah untuk mengetahui performa produksi seperti pertumbuhan, kelulushidupan ikan lele dumbo (Clarias gariepinus), pertumbuhan kangkung dan mengetahui efektivitas sistem biofilter akuaponik terhadap penurunan amonia. Penelitian dilakukan pada bulan Desember 2014–Maret 2015 di Laboratorium Budidaya Perairan, Universitas Diponegoro, Semarang. Variabel yang dikaji meliputi laju pertumbuhan spesifik (SGR) (%bobot/hari), biomassa mutlak (g), kelulushidupan (SR) (%), tingkat konsumsi pakan (g), rasio konversi pakan (FCR), efisiensi pemanfaatan pakan (%), efektivitas sistem biofilter akuaponik, rata-rata bobot kangkung (g) dan kualitas air. Penelitian menggunakan rancangan acak lengkap (RAL) dengan 2 perlakuan dan 3 ulangan, yaitu perlakuan A (sistem biofilter akuaponik) dan perlakuan B (sistem konvensional). Hasil penelitian menunjukkan bahwa sistem biofilter akuaponik dan sistem tanpa biofilter akuaponik (konvensional) berbeda sangat nyata (sign<0,01) terhadap SGR, biomassa mutlak (g), FCR dan efisiensi pemanfaatan pakan dan berbeda nyata (sign<0,05) terhadap SR dan tingkat konsumsi pakan. Sistem biofilter akuaponik memberikan hasil lebih baik dibandingkan dengan sistem konvensional. Hasil dari sistem biofilter akuaponik yaitu SGR 4,21±0,06 %bobot/hari, biomassa mutlak 29353,0±2417,58 g, SR 92,71±1,88 %, tingkat konsumsi pakan 36166,67±1527,52 g, FCR 1,15±0,02, efisiensi pemanfaatan pakan 81,07±3,30%. Kadar amonia dalam sistem ini masih dalam kisaran yang layak untuk pembesaran ikan lele dumbo hingga minggu ke 8. Berdasarkan hasil penelitian ini maka dapat disimpulkan bahwa sistem biofilter akuaponik dapat meningkatkan performa produksi ikan lele. The increase in aquaculture production in Indonesia pursued by utilizing land optimally. Closed system culture will produce waste from the metabolism which sustainably reach the level that are toxic to fish. One effort to overcome the problem that the environmental management of aquaculture with biofilter aquaponics system. This study was aimed to know the production performance such as growth, survival of african catfish (Clarias gariepinus), spinach water growth and to know the effectiveness of the biofilter aquaponics system to decrease ammonia. The study was conducted on December 2014-March 2015 in the Laboratory of Aquaculture, Diponegoro University, Semarang.Variables that were examined include the specific growth rate (SGR) (% weight / day), an absolute biomass (g), survival rate (SR) (%), the level of feed intake (g), feed conversion ratio (FCR), efficiency feed utilization (%), the effectiveness of the biofilter aquaponics system, the average weight of spinach water (g) and water quality. Research using a completely randomized design (CRD) with 2 treatments and 3 replications, namely treatment A (biofilter aquaponics system) and treatment B (conventional system).The results showed that the biofilter aquaponics system and the system without a biofilter aquaponics (conventional) highly significant different (sign <0.01) on SGR, an absolute biomass (g), FCR and feed utilization efficiency and significantly different (sign <0.05) on SR and the feed consumption rate. Biofilter aquaponics system gives better results than conventional systems. Results of aquaponics biofilter system that was SGR 4.21 ± 0.06% weight / day, an absolute biomass 29353.0 ± 2417.58 g, SR 92.71 ± 1.88%, the level of feed intake 1527.52 ± 36166.67 g, FCR 1.15 ± 0.02, 81.07 ± 3.30%  efficiency of feed utilization. Levels of ammonia in the system was still in a reasonable range for fish rearing african catfish until week 8. Based on these results it can be concluded that the biofilter aquaponics system can improve production performance of catfish.

Abstract

Marble Goby is a fresh water fish with high economic value. The marble goby grow-out business require fish seed  from various seedling Centres. To obtain such output require adequate seeds supply from many sources as well as appropriate transportation. The optimum density of Marble Goby seed in closed transportation is not yet known, therefore, a research on this issue is needed to ensure fish seed quality and survival rate.The aim of this study is to observe the effect of different densities on the survival rate of Marble Goby sized 100 g/ind. and to observe the best density during their transportation using 10 hour – closed system. This study applied a  complete random design method with 4 density treatments, which consist of 6 ind./L, 8 ind./L, 10 ind./L, and 12  ind./L. Each treatment was subject to three replications. Data used were survival rate, energy, activity, and water quality. The study found that different density resulted in significant effect (P < 0.01) on the survival of marble goby seeds. Survival rates of each treatment are as follows: (A) 100%, (B) 95.83%, (C) 93.33%, and (D) 80.56%.  Treatment B with density rate of 8 ind/L provided the most reliable density related to the transportation of marble goby using a 10 hour – closed system. Key words: marble goby, transportation, density, survival.
