Abstract

Abstract Indonesia is an archipelago that is rich in diversity of flora and fauna. One of these is a wealth of fauna species of sea turtles. All species of sea turtles in the world by the Convention on International Trade in Endangered Species of Wild Flora and Fauna (CITES) put in Appendix I as endangered and protected and not allowed to be traded. The purpose of this study was to determine effect the ratio of the depth from nest egg incubation and hatching percentage of green turtles (Chelonia mydas) nests at different depths in Sukamade, Betiri Meru National Park, Banyuwangi, East Java. The design of the study is a randomized block design (RGD). The groups as replicates for RGD, between groups or experimental material media are considered uniform. The results showed that the average incubation period was 58.87 +0.39 days, then the results were followed by Duncan's multiple range test, which showed that the highest yield obtained by the depth of 50 cm wasn't significantly different (p> 0.05) with depth of 30 cm and 70 cm. While the results obtained at the lowest depth of 90 cm was significantly different (p <0.05) with the other depth (30 cm, 50 cm and 70 cm). While the percentage of hatching success obtained in average hatching was 88.12 + 0.38%. The Duncan's multiple range test analysis, showed that at a depth of 70 cm were not significantly different (p <0.05) from depth of 50 cm, but 70 and 50 cm depth was significantly different (p> 0.05) from another depth. Whereas the lowest hatching results obtained on depth of 90 cm are significantly different (p> 0.05) from the other depth (30 cm, 50 cm and 70 cm). The conclusion of this study was different depth of green turtle nests affect the egg incubation period and the percentage of egg hatching success of green turtles.

Abstract

Abstract Kembung fish (Rastrelliger sp.) is a pelagic fish with high catching production volumes. The high catching volume require the fishermen and traders to maintain the quality of fish because fish is highly perishable product. Formalin abbuse as a substance to inhibit deterioration of fish induce natural substances exploration as formalin substitute in the field. One of these natural substances which widely cultivated in Indonesia is Kappaphycus alvarezii. This study aim to determine the effect of red algae (K.alvarezii) on the quality of kembung fish. The research method is experimental with a Completely Randomized Design (CRD). The treatment used is different soaking solution concentration, namely A (K.alvarezii 0%), B (K.alvarezii 25%), C (K.alvarezii 50%), D (K.alvarezii 75%) and E (formalin 1%) with four repetitions in each treatment. The primary parameters measured were the total bacterial count and organoleptic of kembung fish. The secondary parameters measured were pH of kembung fish meat. The data analyzed by Analysis of Variance (ANAVA) and the differences between treatments were determined by Duncan's Multiple Range Test. The results showed that the red algae (K.alvarezii) with concentrations 0%, 25%, 50% and 75% significantly (p<0,05) on the quality of kembung fish. K.alvarezii able to inhibit the bacterial growth, but the organoleptic value (visibility, odor and texture) is lower than formalin. Based on these results, further research is needed regarding the use of appropriate concentrations so that the quality of kembung fish maintained as before the treatment (either from the total bacterial count and organoleptic value).

Abstract

Abstract Vibrio harveyi is the most common pathogenic agent of Penaeus monodon and causing large economic losses to the shrimp farming industry. Antibiotic has been used as the diseases treatment, but it has been banned due to the side effects. This problem was required an alternative solution by using natural material, such as earthworm powder (L. rubellus). This research was conducted to know the bacterial growth inhibition V. harveyi by using earthworm powder (L. rubellus). The research method is experimental and data analysis done descriptively. Inhibition of V. harveyi growth was tested using disc diffusion method. Earthworm powder concentrations are 0, 25, 50, 75, 100 % (w/v) and chloramphenicol disc (30µg), each treatment was repeated three times. The main parameter observed was the size of diameter inhibition zone (mm) which formed around the disc paper after incubation within 24 hours. The data analysis was done descriptively by comparing sensitivity level each treatment. Results showed that earthworms powder (L. rubellus) from the lowest concentration (25% w/v) to the highest concentration (100% w / v) were not able to inhibit V. harveyi growth.

Abstract

Rumput laut dari kelompok Chlorophyta dan Rhodophyta banyak dimanfaatkan di Indonesia sebagai bahan pangan. Caulerpa racemosa, salah satu jenis Chlorophyta, mengandung senyawa bioaktif antioksidan dan antibakteri di antaranya terpenoid, polifenol, alkaloid, dan flavonoid. Tujuan penelitian untuk menentukan kondisi ekstraksi optimal (konsentrasi, rasio padatan:pelarut, dan lama waktu) C. racemosa menggunakan Deep Eutectic Solvents (DES) berdasarkan aktivitas antioksidan dan antibakteri. Penelitian ini menggunakan variabel bebas (konsentrasi DES 5, 10, 15%), padatan : pelarut (1:10, 1:15, 1:20) dan lama waktu maserasi (24, 48, 72 jam). Proses optimasi dilakukan menggunakan metode Response Surface Methodology (RSM) dengan rancangan Box–Behnken melalui perangkat lunak Design Expert versi 13. Aktivitas antioksidan ekstrak C. racemosa berkisar antara 28,46±0,067 hingga 50,50±0,067 mg TE/g DW. Konsentrasi pelarut DES dan waktu maserasi berpengaruh signifikan (p < 0,05), sedangkan rasio padatan terhadap pelarut tidak menunjukkan pengaruh signifikan (p > 0,05). Aktivitas antioksidan menurun pada 15% DES akibat perbedaan polaritas dan viskositas pelarut, sementara viskositas yang lebih rendah meningkatkan efisiensi ekstraksi. Kondisi optimum diperoleh pada 10% DES, rasio 1:20, dan waktu maserasi selama 72 jam.  Aktivitas antibakteri terhadap Vibrio harveyi (13 mm) dan Vibrio parahaemolyticus (14,8 mm) juga tertinggi pada kondisi tersebut, kemungkinan karena peningkatan ekstrak senyawa bioaktif. Hasil ini menunjukkan bahwa metode ekstraksi teroptimasi ini dapat direkomendasikan untuk pengembangan produk akuakultur dan pangan fungsional.

Abstract

Nannochloropsis oculata is a microalgae that acts as a natural food source in fisheries. The need for N. oculata can be met through progressive culture starting from laboratory scale culture to provide inoculant stock to mass culture using concrete tubs. The culture of N. oculata begins with the preparation and sterilization of culture media and equipment, fertilizer production, microalgae culture starting from the laboratory scale, intermediate scale, and mass scale, observing the density of microalgae and water quality. The lag phase of N. oculata occurs on the first and second days, the exponential growth phase lasts for four days, followed by a stationary phase that occurs on the seventh day. Peak population density of  N. oculata on all culture scales occurred on day 6 with culture density in glass containers 14.58x106 cells/mL, carboy culture 11.6x106 cells/mL, intermediate culture 5.1x106 cells/mL, and mass culture 9.85 x106 cells/mL. The growth rate of microalgae N. oculata from the beginning of growth to day 6 was highest on the intermediate scale. The size of the container and the different composition of fertilizer at each culture scale caused differences in the peak population density and growth rate of N. oculata. Production of  N. oculata can be carried out in bulk while still paying attention to every stage of culture preparation and microalgae culture activities as a standard operating procedure for microalgae culture to prevent contamination. Keywords: progressive culture, microalgae, Nannochloropsis oculata
