Judul: GROWTH PERFORMANCE OF CATFISH (Clarias gariepinus) WITH ADDITION OF IRON (Fe) MINERALS IN FEED
Abstrak: Pengaruh penggunaan mikro mineral Fe (zat besi) pada pakan sangat mempengaruhi kinerja produksi pertumbuhan ikan lele (Clarias gariepinus). Penelitian ini bertujuan menentukan dosis yang tepat terkait penambahan zat besi (Fe) pada pakan yang mampu meningkatkan pertumbuhan ikan lele (Clarias gariepinus). Formulasi pakan dengan kadar Fe berbeda, sebagai perlakuan dalam penelitian ini, menggunakan lima perlakuan dengan masing-masing dosis 0, 15, 30, 60, dan 120 mg kg-1 yang diberikan pada benih ikan lele dengan bobot rata rata awal 9,49±0,01 g sebanyak 15 ekor/akuarium dengan ukuran 90x45x45 cm dan ketinggian air 30 cm. Setelah masa pemeliharaan selama 60 hari, persentase peningkatan bobot sebanyak 409,1% pada perlakuan Fe 30 mg kg-1 pakan, sedangkan pada perlakuan kontrol yang tidak dilakukan penambahan Fe pada pakan, mengalami peningkatan sebesar 309,1%. Hasil penelitian menunjukkan bahwa parameter kinerja pertumbuhan (biomassa akhir, bobot individu akhir, tingkat kelangsungan hidup, dan laju pertumbuhan spesifik) pada ikan lele yang diberi dosis Fe menunjukkan hasil yang berbeda nyata (p<0,05) terhadap ikan lele dengan perlakuan kontrol. Berdasarkan hasil dari penelitian ini penggunaan dosis terbaik terhadap penambahan Fe pada pakan yaitu 30 mg kg-1 pakan., The influence of micro mineral Fe (iron) usage in feed greatly affects the performance and growth of catfish (Clarias gariepinus). This study aims to determine the appropriate dosage of iron (Fe) supplementation in the feed that can enhance the growth of catfish (Clarias gariepinus). Feed formulations with different Fe levels were used as treatments in this research, consisting of five treatments with doses of 0, 15, 30, 60, and 120 mg kg-1, given to catfish juveniles with an average initial weight of 9.49±0.01 g, totaling 15 individuals per aquarium measuring 90x45x45 cm with a water height of 30 cm. After a 60-day rearing period, the percentage of weight gain was 409.1% in the treatment with 30 mg kg-1 Fe in the feed, while the control treatment without Fe supplementation in the feed experienced an increase of 309.1%. The research results indicate that growth performance parameters (final biomass, final individual weight, survival rate, and specific growth rate) in catfish given Fe doses show statistically significant differences (p<0.05) compared to the control treatment. Based on the findings of this study, the optimal dosage for Fe supplementation in the feed is 30 mg kg-1.

Abstrak: Penelitian ini bertujuan untuk mengevaluasi pengaruh suplementasi tepung daun kayu manis pada pakan terhadap kinerja pertumbuhan ikan lele (Clarias gariepinus). Penelitian menggunakan empat perlakuan yaitu penambahan tepung daun kayu manis sebanyak 0%, 0,5%, 1,0%, dan 1,5% pada pakan komersial. Ikan lele dipelihara dalam waring 1x1x1 m3 yang diletakkan di dalam kolam beton dengan padat tebar 20 ekor/waring selama 30 hari. Ikan lele diberi pakan secara at satiation. Hasil penelitian menunjukkan bahwa penambahan tepung daun kayu manis pada pakan tidak memengaruhi rasio konversi pakan, namun penambahan daun kayu manis 1,5% pada pakan dapat meningkatkan pertumbuhan ikan lele dan menurunkan kadar lemak dagingnya (P<0,05). Kesimpulan penelitian ini penambahan tepung daun kayu manis pada pakan berpengaruh terhadap kinerja pertumbuhan ikan lele (C. gariepinus)., This study aims to evaluate the effect of cinnamon leaf powder supplementation on feed on the growth performance of Clarias gariepinus catfish. The study used four treatments, namely the addition of cinnamon leaf flour as much as 0%, 0.5%, 1.0%, and 1.5% in commercial feed. The catfish were kept in a 1x1x1 m3 net placed in a concrete pond with a stocking density of 20 fish/net cage for 30 days. Catfish were fed at satiation. The results showed that the addition of cinnamon leaf powder to the feed did not affect the feed conversion ratio, but the addition of 1.5% cinnamon leaf to the feed increased the growth of catfish and reduced the fat of meat (P<0.05). So it can be concluded that the addition of cinnamon leaf powder to feed had a significant effect on the growth of Clarias gariepinus catfish.

Abstrak: Existing design of the telephone public network is susceptible to eavesdropping on its voice stream. Consequently, any wire taper can listen to supposedly private conversation. In order to prevent such eavesdropping, we propose a protocols and its implementation for end-to-end voice privacy authenticate as a service available for interested subscribers. Our protocols consist of customer enrollment system, customer authentication system and simulation voice privacy. Protocols that we made are adaptation from Sharif and Wijekesera journal with the title Providing Voice Privacy as a Service over the Public Telephone Network. The result of the process shows how the customer enrolls and how the system process the password, how the system authenticate customer simulate voice privacy.
