Judul: Fish hold design of live fish carrier based on technique, risk mitigation and fish survival aspects
Abstrak: The continuity of humpback grouper (Cromileptes altivelis) culture activity is influenced by availability of juvenile in lot of number in the right time, right size, and right quality. A certain method and transportation moda is needed due to a long distance between location of hatchery and rearing (growing) location in order to maintain high survival ratio. Nowadays, closed system method is applied for transporting juvenile of hunchback grouper with total length of less than 8 cm. In this method, the juveniles are put into the plastic bag with sea water and oxygen of certain composition before transported by land, sea or air transportation moda. By using this method some limitations appear such as, amount of fish juveniles and time needed for transportation. The objectives of this research are: 1) to determine the risk level of life fish carrier with ‘opened system’ to mortality ratio of fish juvenile with total length (TL) 5 – 7 cm and its risk source, 2) to determine the risk mitigation steps that can reduce level of fish juveniles mortality and 3) to determine the design of life fish carrier that can transport fish juveniles, especially the design related to existence of fish juveniles in the fish hold during transportation. Literatures review, laboratory experiments simulations, and numerical analysis methods have been applied in this research. An asessment to open system life fish carrier transporting juvenile with 5 – 7 cm TL was carried out. In general, this kind of carrier was used to transport juvenile of minimum 16 cm TL. Transporting juvenile with 5 – 7 cm TL by using open system carrier indicates high risk. A risk mitigation attempt was done by designing a fish hold equipped with resirculation water system and optimizing the amount of juveniles that could be transported in the fish hold. The result of this mitigation process showed that fish hold with keel damper constructed at the inner wall was able to reduce free surface effect during ship rolling and to maintain the ship stability toward free surface effect occured during rolling. Besides, keel damper gives positive effect in increasing oxygen concentration in the fish hold during rolling event. Another result showed that the use of combination between recirculation and aeration shows a good perfomance to maintain sea water quality in the fish hold. A certain amount of juveniles that were put in the fish hold model for simulation of the designed system resulted in the stability of seawater quality in the fish hold during the experiment and 100% survival ratio of juvenile at the end of 48 hours experiment. Based on the above result, recomended transportation moda for fish juvenile with 5 – 7 cm TL in large amount with long sailing time and high survival ratio is closed system of life fish carrier equipped with keel damper and combination system of resirculation and aeration in the fish hold with fish juvenile density depend on the oxygen consumption rate for each individual fish juvenile.

Judul: Addition of Bandotan Leaf Extract (Ageratum conyzoides) to Closed System Transportation of Padang Strain Gourami (Osphronemus goramy)
Abstrak: Kegiatan transportasi ikan hidup pada kegiatan budidaya penting untuk diperhatikan karena berkaitan erat dengan kondisi ikan saat transportasi dan pasca transportasi, sehingga berakibat pada meningkatnya biaya pemeliharaan. Penelitian ini bertujuan menganalisis pengaruh penambahan ekstrak daun bandotan (Ageratum conyzoides) pada transportasi sistem tertutup ikan gurami strain padang (Osphronemus goramy) yang ditransportasikan selama 48 jam terhadap kualitas air, kelulushidupan, respon stres, pertumbuhan ikan pasca transportasi, dan analisis keuntungan. Rancangan penelitian yang digunakan yaitu rancangan acak lengkap (RAL) dengan 4 perlakuan dan 3 ulangan. Perlakuan terdiri dari kontrol dengan kode G1, penambahan esktrak sebanyak 0,2 ml L-1 dengan kode G2, penambahan ekstrak sebanyak 0,4 ml L-1 dengan kode G3, penambahan ekstrak sebanyak 0,6 ml L-1 dengan kode G4. Parameter yang diukur pada penelitian ini yaitu tingkat kelangsungan hidup (TKH), laju pertumbuhan harian (LPH), laju pertumbuhan spesifik (LPS), rasio konversi pakan (RKP), parameter kualitas air (fisika dan kimia), parameter respon stres ikan (kadar hemoglobin, kadar glukosa darah, kadar kolesterol, pH darah, pH daging, tingkat konsumsi oksigen, dan histologi insang. Hasil uji statisik ANOVA menunjukkan penambahan ekstrak daun bandotan terhadap media air transportasi, dan tingkat kelangsungan hidup berbeda nyata (P<0,05). Penambahan ekstrak dengan dosis 0,4 ml L-1 pada media air transportasi yang berisi ikan gurami padang dengan panjang tubuh rata 10,24±0,30 cm dan bobot rata-rata 16,50±0,19 g meningkatkan kelulushidupan sebesar 100% dibanding tanpa penambahan ekstrak dan memiliki nilai keuntungan paling tinggi dibanding perlakuan lainnya., Live fish transportation activities in aquaculture activities are important to consider because they are closely related to the condition of the fish during transportation and post-transportation, resulting in increased maintenance costs. This study aims to analyze the effect of the addition of bandotan leaf extract (Ageratum conyzoides) in closed system transportation of padang strain gourami (Osphronemus goramy) transported for 48 hours on water quality, survival, stress response, post-transport fish growth, and profit analysis. The research design used was a complete randomized design (CRD) with 4 treatments and 3 replicates. The treatments consisted of control with code G1, the addition of extract as much as 0.2 ml L-1 with code G2, the addition of extract as much as 0.4 ml L-1 with code G3, the addition of extract as much as 0.6 ml L-1 with code G4. Parameters measured in this study were survival rate (SR), daily growth rate (ADG), specific growth rate (SGR), feed conversion ratio (FCR), water quality parameters (physical and chemical), fish stress response parameters (hemoglobin levels, blood glucose levels, cholesterol levels, blood pH, meat pH, oxygen consumption rate, and gill histology. The results of ANOVA static test showed the addition of bandotan leaf extract to the transportation water media, and the survival rate was significantly different (P<0,05). The addition of the extract at a dose of 0.4 ml L-1 to the transportation water medium containing Padang gourami with an average body length of 10.24 ± 0.30 cm and an average weight of 16.50 ± 0.19 g increased the survival rate by 100% compared to without the addition of the extract and had the highest profit value compared to other treatments.
