The aim of this study was to examine the effect of vitamin E on gonad maturation and determining the best doses in improving gonad maturation in nilem fish. In this study used a flockof fishbrood which is never experienced spawning. There are 4 doses of vitamin E which used in this research following by 0, 125, 250, and 375 mg/kg. The results showed that fortifiedof vitamin E which were in feed significantly affected to the percentage of gonad development, gonadosomatic index (GSI), hepatosomatic index (IHS), fecundity, the diameter of eggs, and the percentage of egg maturity at P<0.05. The result showed that the best dose of vitamin E to reach gonad maturity was 375 mg kg-1 with six weeks maintenance. The percentage of gonad maturity was 100%, IGS was 11.50%, IHS was 0.34%, fecundity was 23.484 eggs/individual, the diameters of the eggs were 0.31 mm, and the percentage of mature eggs was 64.44%. These results supported the potential of feed additives such as vitamin E plays a critical role in enhancing gonad maturation in nilem fish thereby providing methods to improve fish reproduction
Kabupaten Sumba Timur merupakan salah satu daerah dengan sumber daya perikanan yang melimpah, namun saat ini belum terdapat data jumlah konsumsi dan asupan gizi ikan masyarakat pesisir. Tujuan penelitian adalah mengetahui profil konsumsi ikan, angka konsumsi ikan, dan status asupan gizi ikan masyarakat pesisir di Kabupaten Sumba Timur. Penelitian ini dilakukan pada bulan Mei—Juni 2020, di sepuluh desa dan dua kelurahan pesisir. Jumlah responden yang dilibatkan adalah 347 orang, yang dipilih menggunakan metode slovin dengan kriteria usia responden 18—60 tahun dan memiliki preferensi tentang ikan. Pengambilan data profil konsumsi ikan dilakukan dengan wawancara, sedangkan angka konsumsi ikan dan status asupan gizi ikan harian menggunakan instrumen food frequency questionnaires. Data hasil penelitian dianalisis deskriptif dan analisis regresi linier tunggal untuk mengetahui hubungan karakteristik keluarga terhadap jumlah konsumsi ikan (kg/kapita/bulan). Hasil penelitian menunjukkan mayoritas masyarakat pesisir berpendidikan Sekolah Menengah Pertama (SMP) dan bermatapencaharian nelayan. Masyarakat pesisir sebanyak 56,80% mengkonsumsi ikan 2—5 kg/kapita/bulan dan 43,20% mengkonsumsi ikan > 5 kg/kapita/bulan. Angka konsumsi ikan masyarakat pesisir berdasarkan usia dan jenis kelamin adalah 45,62—48,00 kg/kapita/tahun atau setara dengan 118,37—133,45 gram/kapita/hari. Angka konsumsi ini masih rendah dibandingkan target konsumsi ikan nasional tahun 2020, yakni 56,39 kg/kapita/tahun. Kontribusi angka konsumsi ikan terhadap rata-rata status asupan gizi ikan masyarakat pesisir adalah protein 7,53 (gram/kapita/hari), lemak 1,08 (gram/kapita/hari), dan energi 107 (kkal/kapita/hari). Khusus pada status kecukupan protein ikan harian belum memenuhi standar asupan gizi hewani ikan, yakni minimal jumlah asupannya harus mencapai 18,53 gram/kapita/hari. Oleh sebab itu, perlu dilakukan strategi untuk membudayakan konsumsi ikan pada masyarakat melalui sosialisasi, edukasi, dan diversifikasi produk perikanan.Title: Fish Consumption Analysis of East Sumba Coastal CommunitiesEast Sumba Regency is one of the areas with abundant fishery resources. Currently, there is no data on fish consumption and nutritional intake in coastal communities. The purpose of the study was to find the profile of fish consumption, the number of fish consumption, and the nutritional status of fish in coastal communities in East Sumba Regency. This research was conducted in May—June 2020 in ten and two coastal villages. The number of respondents involved was 347. The number of respondents was determined using the Slovin approach with the criteria of the respondent’s age being 18—60 years and having a preference for fish. Data collection on fish consumption profiles was conducted by interview, while fish consumption figures and daily fish nutritional status used the food frequency questionnaire instrument. The research data were analyzed descriptive and single linear regression analysis to decide the relationship of family characteristics to fish consumption (kg/capita/month). The study results show that most coastal communities have a junior high school education, earning a livelihood from fishermen. Coastal communities 56.80% consume fish 2—5 kg/capita/month and 43.20% consume fish >5 kg/capita/month. The fish consumption rate of coastal communities based on age and gender is 45.62—48.00 kg/capita/year or equal to 118.37—133.45 grams/capita/day. This consumption figure is still low compared to the national fish consumption target in 2020, which is 56.39 kg/capita/year. The contribution of fish consumption figures to the average nutritional status of fish in coastal communities is protein 7.53 (grams/capita/day), fat 1.08 (grams/capita/day), and energy 107 (kcal/capita/day). In particular, the daily fish protein adequacy status does not meet the standard of fish animal nutrition intake, namely the smallest amount of intake must reach 18.53 grams/capita/day. Therefore, a strategy is needed to cultivate fish consumption in the community through socialization, education, and diversification of fisheries products.
Bonylip barb Osteochilus vittatus is a local fish species of significant economic value with vast potential in commercial freshwater fish culture. Traditional cultivation methods are currently employed depending on the seeds, although a low hatchery rate is assumed. The purpose of this study, therefore, was to determine the effect of dietary vitamin E on the quality of bonylip barb eggs, with the applied dosage of 0, 125, 250, and 375 mg/kg. Subsequent parameters measured include fecundity, drowned egg percentage, the chemical composition of eggs, and total energy retention. The results showed that several vitamin E doses significantly (P˂0.05) influenced these aforementioned constraints. Furthermore, the application of vitamin E at 375 mg/kg recorded the best dosage to improve egg quality. In addition, the fecundity was estimated at 23.484 grains, and sink egg percentage reached 92.66%, while protein and fat content were 21.43 mg/kg and 27.88%higher compared to the controlled sample. Therefore, It is concluded that the administration of vitamin E in the feed tends to increase egg quality of bonylip barb fish.
Pembuatan dasar bakso ikan selalu menggunakan tepung atau pati sebagai bahan pengikat. Tepung tapioka merupakan salah satu bahan pengikat yang digunakan untuk meningkatkan daya ikat air, akan tetapi mempunyai pengaruh yang kecil terhadap emulsifikasi dalam menghasikan kualitas bakso yang baik. Penambahan bubur rumput laut dalam pembuatan bakso ikan dapat memperbaiki kualitas produk karena sifat fungsional rumput laut sebagai emulsifier. Penggunaan rumput laut sebagai bahan tambahan dalam pembuatan bakso ikan dapat meningkatkan nilai gizi dan kandungan serat pada produk bakso. Penelitian ini bertujuan untuk mengkaji penambahan bubur rumput laut Eucheuma cottoni terhadap mutu bakso ikan kakap dan menentukan konsentrasi penambahan bubur rumput laut terbaik pada bakso ikan kakap. Metode penelitian yang digunakan adalah metode eksperimen dengan 15 panelis dan 4 perlakuan penambahan bubur rumput laut yakni 0%, 20%, 40%, 60%. Parameter yang diamati adalah uji organoleptik (rasa, aroma, dan kekenyalan) dan analisis kimiawi bakso ikan kakap. Hasil penelitian menunjukkan bahwa semua perlakuan bakso ikan dengan penambahan bubur rumput laut masih disukai oleh panelis. Namun, perlakuan penambahan bubur rumput laut sebesar 20 % merupakan perlakuan bakso ikan yang paling disukai oleh panelis dengan skor rasa 6.5 (sangat suka), aroma 7.5 (sangat suka), dan kekenyalan 4.6 (sangat kenyal). Selain itu, penambahan bubur rumput laut sebanyak 20 % menghasilkan kadar air sebesar 74.0 %, kadar abu 1.3%, kadar lemak 1.4%, dan kadar protein 12.7%. Bakso ikan kakap dengan penambahan bubur rumput laut telah memenuhi standar SNI 01-7266-2014.
