KKP. Ikan ini sangat digemari masyarakat karena memiliki cita rasa yang khas, kandungan protein tinggi, dan dapat dikonsumsi segar serta bahan olahan. Berdasarkan informasi pasar tahun 2012 bahwa nilai ekonomis ikan patin relatif tinggi, harga telur Rp5 sampai Rp7/butir, harga benih 0,75 inci Rp60/ekor, dan harga benih ukuran 1 PENDAHULUAN ABSTRACTCatfish hatchery requires technology and engineering to maximize the development and growth of fish. In this research the hormone thyroxine (T4), recombinant growth hormone (G) and mix of thyroxine and growth hormones (GT) were administered by immersion to enhance the development and growth of stripped catfish larvae. Research was using completely randomized design, with four treatments and five replications; A, control; B, thyroxine hormone ( The size of liver cell and cytoplasm of treated larvae were larger than the control. Behavior of fish in the treatments B and C showed more active than the treatments A and D. Thus, combination of thyroxine and recombinant growth hormone treatment (C) has an efficient of yolk utilization, and higher in development and growth of stripped catfish larvae.Keywords: thyroxine, growth hormone, yolk absorption, growth, stripped catfish ABSTRAKPembenihan ikan patin membutuhkan teknologi dan rekayasa untuk memaksimumkan perkembangan, dan pertumbuhan ikan. Pada penelitian ini dilakukan pemberian hormon tiroksin (T4), hormon pertumbuhan rekombinan (G) serta hormon gabungan antara hormon tiroksin dan hormon pertumbuhan (GT) melalui perendaman untuk memacu perkembangan dan pertumbuhan larva ikan patin siam. Penelitian menggunakan rancangan acak lengkap, dengan empat perlakuan dan lima kali ulangan; A, kontrol; B, hormon tiroksin (T4) 0,1 mg/L; C, T4 dan G (GT) (0,1 mg/L dan 10 mg/L); dan D, G 10 mg/L. Perendaman dilakukan selama satu jam. Hasil penelitian menunjukkan bahwa laju penyerapan kuning telur pada jam ke-16 setelah perendaman lebih cepat (P<0,05) pada perlakuan B (96,98%) dibandingkan dengan perlakuan A (18,54%), C (20,59%), dan D (32,90%). Pertumbuhan larva yang diberi perlakuan B (24,85 mm) dan C (24,00 mm) lebih tinggi (P<0,05) dibandingkan dengan perlakuan A (21,71 mm) dan D (23,18 mm). Tingkat kelangsungan hidup antarperlakuan tidak berbeda (P>0,05). Ukuran sel dan sitoplasma hati ikan perlakuan relatif lebih besar dibandingkan kontrol. Tingkah laku ikan pada perlakuan B dan C lebih aktif dibandingkan perlakuan A dan D. Dengan demikian kombinasi hormon tiroksin dan hormon pertumbuhan rekombinan secara bersama (C) memiliki efisiensi pemanfaatan kuning telur, perkembangan, dan pertumbuhan lebih tinggi pada larva ikan patin.Kata kunci: tiroksin, hormon pertumbuhan, penyerapan kuning telur, pertumbuhan, ikan patin siam
Dietary adherence is one of the requirements in chronic disease management, which the success of hypertension management may correlate with the social support perceived by the patients. The study aimed to identify the relationship between social support and dietary adherence among patients with hypertension in Primary Health Centre, Tangerang. The study was a descriptive correlational, cross-sectional study, in which 120 respondents were recruited by using purposive sampling. Multidimensional Perceived of Social Support (MSPSS) and Dietary Adherence questionnaire was used based upon validity and reliability to measure social support and adherence. Pearson Product-Moment Correlation Coefficient was used to examine the relationship between social support and dietary adherence. The analysis result indicated that respondents who reported low support were 51 respondents (42.5%), and low dietary adherence was 53 respondents (44.2%). The analysis results showed there was a significant positive relationship between social support and dietary adherence among patients with hypertension, in which the power of correlation was moderate (r = 0.49, p < 0.05). Patients with hypertension who perceived higher social support more likely to adhere to the dietary of hypertension. The result suggests that health care providers need to facilitate support from friends, family, and significant others of the patients to achieve optimum dietary adherence.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
