Abstract

ABSTRAKIkan mas adalah salah satu ikan air tawar yang bersifat herbivor. Pakan sebagai sumber nutrien dalam pembesaran ikan mas umumnya terbuat dari beberapa campuran bahan baku nabati. Penggunaan bahan baku nabati tanpa pengolahan dapat menurunkan pertumbuhan ikan karena kandungan serat dan zat antinutrisnya yang relatif tinggi. Cairan rumen sapi merupakan salah satu bahan kaya akan enzim dan mikroorganisme yang berperan dalam menurunkan serat kasar dan zat antinutrisi pada bahan nabati pakan. Penelitian ini bertujuan untuk mendapatkan dosis cairan rumen sapi yang tepat sebagai bahan fermentasi pada seluruh bahan nabati pakan dalam meningkatkan pertumbuhan dan kelangsungan hidup benih ikan mas. Penelitian didesain menggunakan rancangan acak lengkap. Perlakuan yang diujikan yakni dosis penggunaan cairan rumen sapi (0%, 25%, 50% dan 75% dari bobot bahan nabati pakan). Hasil analisis menunjukkan bahwa penggunaan cairan rumen sapi sebagai bahan fermentasi bahan nabati dalam pembuatan pakan memberikan pengaruh nyata (p0,05) terhadap laju pertumbuhan spesifik harian (LSPH), pertambahan bobot individu (PBI), rasio konversi pakan (RKP). LSPH dan PBI tertinggi serta RKP terendah diperoleh pada perlakuan dosis cairan rumen sapi 75% per bobot sampel bahan nabati yakni secara berurut sebesar 2,87 % hari-1, 1,18 g dan 1,77. Kelangsungan hidup selama pemeliharaan untuk semua perlakuan berkisar antara 66,67-80,0%. Kualitas air selama pemeliharaan meliputi pH (5,8-8,1), suhu (28-30 ºC), oksigen terlarut (5,0-6,8 ppm), dan amonia  (0,05-0,01 ppm) masih dalam kategori sesuai untuk pemeliharaan benih ikan mas. Dosis penggunaan cairan rumen sapi sebagai bahan fermentasi bahan baku nabati pakan yang memberikan nilai terbaik diperoleh pada perlakuan D (75% cairan rumen sapi).Kata Kunci: Bahan baku pakan, Kelangsungan hidup, Rasio konversi pakanABSTRACTThe carp (Cyprinus carpio) is a herbivorous freshwater fish. Feed as a source of nutrients in carp grow-out is generally made from a mixture of plant-based ingredients. The use of unprocessed plant materials can inhibit fish growth due to the relatively high fiber and anti-nutrient content. Bovine rumen fluid is rich in enzymes and microorganisms that can reduce crude fiber and anti-nutrient content in plant-based feed ingredients. This study aimed to determine the best dose of bovine rumen fluid used as a plant-based feed ingredient fermentation agent in terms of improving the growth and survival of carp fry. The study used a complete randomized design. The treatments trialed were various doses of bovine rumen fluid (0%, 25%, 50% and 75% of plant-based feed ingredients by weight). The results showed that using bovine rumen liquid to induce fermentation of plant-based feed ingredients during feed manufacturing had a significant effect (p0.05) on specific growth rate (SGR), individual weight gain (IWG), and feed conversion ratio (FCR). The highest SGR and IWG and the lowest FCR (2.87% day-1, 1.18 g and 1.77, respectively) were obtained under the bovine rumen fluid dose of 75% plant-based ingredient weight. Across all treatments, survival rate during the study period ranged from 66.67-80.0%. Water quality remained within suitable ranges for carp fry rearing, as follows: pH (5.8-8.1), temperature (28-30ºC), dissolved oxygen (5.0-6.8 ppm), and ammonia (0.05-0.01 ppm). The dosage of bovine rumen fluid that provided the best results when used as a fermentation agent for plant-based ingredients in carp fry feed was treatment D (75% bovine rumen fluid by weight).Key words: Feed ingredients, Survival, Feed conversion ratio.

Abstract

ABSTRAKKeberhasilan pertumbuhan anggur laut Caulerpa lentillifera yang dikultur bersama dengan udang windu ditentukan oleh posisi yang tepat untuk menerima nutrien secara maksimal. Penelitian ini bertujuan untuk mengevaluasi pertumbuhan anggur laut dan udang windu pada posisi tanam di dasar dan lepas dasar di dalam tambak tradisional masing-masing dengan 10 ulangan.. Hapa berukuran 1x1 m dan nampan 25x25 cm digunakan untuk memelihara kedua spesies ini. Selama masa pemeliharaan 35 hari, udang windu tidak diberi pakan buatan untuk mempertahankan tipikal tambak tradisional sebagai pemasok bahan pangan organik. Uji t independen mengindikasikan Laju Pertumbuhan Spesifik (LPS) anggur laut dan udang windu di dasar tambak (1,98 ± 0,32% dan 3,68±0,11% per hari) secara signifikan (p0.05) lebih tinggi dibandingkan lepas dasar (1,59±0,29% dan 3,50±0,31% per hari). Sementara itu, Efisiensi Reduksi Nutrien (ERN) dari Total Amonia Nitrogen (TAN) sebesar 38,53±4,48% yang mengindikasikan kemampuan C. lentillifera menyerap bahan anorganik. Studi menyimpulkan bahwa ko-kultur C. lentillifera dan udang windu memiliki efek sinergitas yang positif dan dapat dikembangkan di tambak tradisional. Untuk hasil yang lebih baik, disarankan C. lentillifera ditanam pada dasar tambak dan dikultur bersama dengan udang windu.Kata Kunci: anggur laut, ko-kultur, pertumbuhan, tambak tradisional, udang winduABSTRACTThe successful growth of sea grapes Caulerpa lentillifera co-cultured with tiger prawns is determined by the appropriate position to absorb maximum nutrients. This study aims to evaluate the growth of sea grapes and tiger shrimp in bottom and off-bottom planting position in traditional ponds with 10 replicates each.  Hapa 1x1 m and trays of 25x25 cm were used to rear these two species. During the 35-day rearing period, tiger shrimp were not artificially fed to maintain traditional ponds typical of organic food suppliers. The independent t-test indicated that the Specific Growth Rate (SGR) of sea grapes and tiger prawns at the bottom (1.98 ± 0.32% and 3.68 ± 0.11% day-1) were significantly (p0.05) higher than off the bottom (1.59±0.29% and 3.50±0.31% day-1). Meanwhile, the Nutrient Reduction Efficiency (ERN) of Total Ammonia Nitrogen (TAN) was 38.53 ± 4.48%, which indicated the ability of C. lentillifera to absorb inorganic materials. The study concluded that the co-culture of C. lentillifera and tiger shrimp had a positive synergistic effect and could be developed in traditional ponds. For better results, it is recommended to plant C. lentillifera at the bottom of the pond and co-culture with tiger shrimp.Keywords: co-culture, growth, tiger prawns, sea grapes, traditional pond

Abstract

ABSTRAK                                                           Telah dilakukan penelitian tentang peranan tanaman sebagai biofilter untuk menjaga kualitas air media. Penelitian ini dilakukan dengan beberapa rangkaian kerja yang dimulai pada bulan Juni - Agustus 2022 di UPT Laboratorium Terpadu Unkhair Kota Ternate. Penelitian ini dirancang dengan menggunakan Rancangan Acak Lengkap (RAL) yang terdiri 3 perlakuan dan 3 ulangan selama 60 hari. Pengukuran dilakukan terhadap suhu, salinitas, DO dan pH, amoniak, nitrat dan nitrit pada setiap minggu. Estimasi dilakukan terhadap efektifitas biofilter tanaman terhadap ammonia (N) dan fosfor (P) pada setiap perlakuan, pertumbuhan mutlak dan sintasan (SR) udang galah dan dianalisis menggunakan ANOVA dengan uji F pada taraf kepercayaan 95%. Uji Fisher (LSD) dilakukan apabila perlakuan berpengaruh nyata terhadap peubah yang diukur (P0.05). Hasil analisis memperlihatkan bahwa ketiga perlakuan tanaman tidak berbeda dalam menyerap N dari limbah budidaya udang galah. Sedangkan untuk penyerapan P dari ketiga perlakuan, jenis pakcoy menyerap paling efektif (0.725 mgL-1) dibandingkan dengan tanaman seledrei (0.540mgL-1) dan selada (0.186 mgL-1) (P0,05). Selain itu pula, konsentrasi ammonia selama penelitian cenderung menurun. Pertumbuhan mutlak dan laju pertumbuhan spesifik pada ketiga perlakuan tidak signifikan berpengaruh (P0,05), sedangkan sintasannya signifikan berpengaruh (P0,05). Meskipun demikian, ketiga tanaman dapat digunakan sebagai biofilter dalam system akuaponik.Kata kunci: Biofilter, tanaman, akuaponik, limbah, udang galahABSTRACTIt has been studied how plants can act as biofilters to preserve the standard of media water. The UPT Unkhair Integrated Laboratory in Ternate City will be the site of this research, with work series beginning in June 2022 and lasting through August 2022. Three treatments and three replications were used in this study's completely randomized design (CRD), which lasted for 60 days. Temperature, salinity, DO and pH, ammonia, nitrate, and nitrite were all measured on a weekly basis. ANOVA with the F test and a 95% confidence level were used to estimate the efficiency of the plant biofilter against ammonia (N) and phosphorus (P) in each treatment, absolute growth, and survival (SR) of gigantic prawns. When the treatment had a significant impact on the measured variables (P0.05), Fisher's test (LSD) was applied. The analysis's findings demonstrated that N absorption from the giant prawn industry's waste did not differ between the three plant treatments. Regarding the three treatments' P absorption, pakchoi (0.725 mgL-1) absorbed P more efficiently than celery (0.540 mgL-1) and lettuce (0.186 mgL-1) (P0.05). Additionally, there was a tendency for the study's ammonia concentration to decline. Survival had a significant influence (P0.05), although the absolute growth and specific growth rates of the three treatments did not (P0.05). However, all three plants can be utilized in aquaponic systems as biofilters.Keyword: Biofilter, plants, aquaponics, waste, giant prawns

Abstract

ABSTRAK Salah satu faktor penentu keberhasilan produksi Budidaya perikanan adalah suksesnya proses transportasi pengiriman ikan dari produsen ikan ke konsumen. Salah satu resiko terbesar dalam sistem transportasi ikan adalah terjadinya stres dan kematian sehingga dapat mengakibatkan kerugian secara ekonomi. Sistem transportasi benih ikan harus mempertimbangkan lama perjalanan, biaya dan keselamatan sampai di tempat tujuan. Resiko kematian ikan dalam transportasi benih dapat merugikan pihak produsen benih dan konsumen. Dalam kajian ini, kami telah melakukan ujicoba dan pengembangan penggunaan bahan kimia racikan sendiri dengan nama ‘propack’ untuk menjaga menjaga kualitas air tetap ideal sehingga ikan saat ditransportasikan dalam kantong plastik tidak mengalami stres dan kematian. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh penambahan tablet ‘Propack’ terhadap tingkat kelulushidupan benih yang ditransportasikan dalam waktu tertentu. Objek penelitian ini menggunakan ikan nila (Oreochromis niloticus) ukuran 3-5 cm. Rancangan Percobaan menggunakan 4 perlakuan dan 5 ulangan sebagai berikut P0 adalah media air hanya oksigen tanpa penambahan tablet” Propack”, sedangkan pada P1 media air dengan oksigen ditambahkan propack sebanyak 40 ppm, P2 media air dengan oksigen ditambahkan propack sebanyak 60 ppm, P3 media air dengan oksigen ditambahkan propack sebanyak 80 ppm. Hasil menunjukkan bahwa kualitas ikan setelah 12 jam perjalanan menunjukkan berbeda nyata dengan antara perlakuan P0 dan P1, P2 dan P3. Pada saat 21 jam P0 mengalami banyak kematian benih sedangkan P1, P2 dan P3 masih bertahan dan sedikit mengalami kematian ikan. Setelah 30 jam dilakukan perhitungan tingkat hidup benih menghasilkan P0(2%), P1(80,6%), P2(81,8%), dan P3(77,6%). Tingkat hidup benih kemudian diuji Anova taraf signifikasi 5% dihasilkan bahwa perlakuan P1, P2 dan P3 berbeda nyata dengan perlakuan P0. Dapat disimpulkan bahwa perlakuan pemberian bahan tablet ‘propack’ dengan dosis 40-60 ppm memberikan hasil tertinggi untuk tingkat hidup benih ikan nila yaitu 80,6% dan 81,8%. Berdasarkan hasil temuan ini, aplikasi tablet ‘propack’ terhadap media air ikan saat transportasi menjadi temuan baru yang bermanfaat dalam proses transportasi ikan nila (Oreochromis niloticus). Kata kunci: Transportasi, nila, propack, oksigen ABSTRACTOne of the determining factors for the success of aquaculture production is the successful process of transporting fish from fish producers to consumers. One of the biggest risks in the fish transportation system is the occurrence of stress and death which can result in economic losses. The fish seed transportation system must consider the length of the trip, costs and safety to the destination. The risk of fish mortality in seed transportation can be detrimental to both seed producers and consumers. In this study, we have conducted trials and developed the use of a self-concocted chemical called 'Propack' to maintain ideal water quality so that when fish are transported in plastic bags, they do not experience stress and death. The purpose of this study was to determine the effect of the addition of 'Propack' tablets on the survival rate of seeds transported at a certain time.The object of this study used tilapia (Oreochromis niloticus) with a size of 3-5 cm. The experiment used 4 treatments and 5 repetitions as follows: P0 is water media with only supplemental oxygen "Propack" tablets, while P1 water media with oxygen is added 40 ppm Propack, P2 water media with oxygen added 60 ppm propack, P3 water media with oxygen 80 ppm of oxygen was added by propack. The results showed that the quality of fish after 12 hours of travel was significantly different from that between treatments P0 and P1, P2 and P3. At 21 hours P0 experienced a lot of death of the fry while P1, P2 and P3 still survived and experienced a few fish deaths. After 30 hours, the survival rate of the seeds was calculated to produce P0(2%), P1(80,6%), P2(81,8%), and P3(77,6%). The seed level was then tested for a 5% ANOVA level of significance which resulted that the P1, P2 and P3 treatments were significantly different from the P0 treatments. It can be said that the administration of the 'propack' tablet material at a dose of 40-60 ppm gave the highest results for the survival rate of tilapia fish, namely 80.6% and 81.8%, respectively. Based on these findings, the application of 'propack' tablets to fish water media during transportation is a new finding that is useful in the transportation process of tilapia (Oreochromis niloticus).Keywords: Transportation, tilapia, propack, oxygen
