Abstract

The purpose of this study was to determine the effect of the frequency of artificial feeding Hi-Pro-Vite 781N-1 on the effective growth of goldfish (Cyprinus carpio) in Timor Leste, Timor. The study used a complete randomized design (CRD) with 3 treatments and 3 replications, in which the conditions of the test unit are carried out according to randomization for all test units. The results of the research conducted for eight weeks (56 days) regarding the frequency for artificial feeding hi-pro-vite 780N-1 were: water temperature, water oxygen, sin water, and total dissolved solids (TDS) of 42.4 ppm, and the results of water quality measurements once a week in the morning (08.00 WIB), on average (20.00 htl) and in the afternoon (05.00) for 8 weeks (58 days). The results obtained during the research week (65 days) fresh at water temperature with a value of 20.2 oC with water oxygen 2.89 pmm, water content 8.3 pmm and TDS 42.4 pmm are indeed a good tolerance for the growth of carp fry (Cyprinus caprio). The behavioral impact of feeding frequency on carp growth and health is explored to refine feeding practices that promote well-being alongside growth. The findings could benefit feed manufacturers and aquaculture stakeholders by informing product development and feeding strategies tailored to maximize growth in carp, contributing to sustainable aquaculture practices. This study offers practical guidance for optimizing feeding practices to enhance growth efficiency, which is crucial for improving fish yield and farm productivity.

Abstract

Silkworm (Tubifex sp.) is one of the natural feeds that has high nutritional value and is used for fish farming. This study aims to determine the effect of the use of different types of feed on the growth of silkworms. The method used in this study is experimental with a complete random design (CRM) consisting of three treatments and one for control, test materials: tofu pulp, chicken manure, sawnut vegetable waste, plantain peel, rice field mud, Em4 and combined according to the research plan. The observed parameters include absolute biomass of the population and individual increase of the population. The results of the study showed that the treatment of each A: 1733 ind/m2 with 34.67 g/m2, B: 2067 ind/m2 with 41.33 g/m2 ,C: 3400 ind/m2 with 68.67 g/m2  and Control (K): 1567 ind/m2 with 31.33 g/m2, counting from the statistical data of the ANOVA Table shows that the Fcout is larger than the Ftable 0.05 and 0.01, which means that the difference is very noticeable with the follow-up test of Smallest Real Difference Test, Treatment C is larger, treatment B, A, K (control) treatment B is larger, treatment A and K (control) while treatment A and K (control) are not significantly different. This means that the type of feed used in treatment C has a significant influence on the increase in population biomass and the increase in the number of silkworm populations compared to others. These results can be further tested with different materials or different containers.

Abstract

Penelitian ini dilakukan dengan tujuan untuk mengetahui pengaruh perbedaan konsentrasi peremdaman hormon metil testosteron terhadap nisbah kelamin ikan nila Oreochromis niloticus, GIFT). Penelitian dilaksanakan di Balai Benih ikan nila GIFT (Genetically Improvement Farmed Tilapia) Dusun Desa Talimoro, Timor Leste. Metode yang digunakan dalam penelitian ini adalah eksperimental/percobaan. Rancangan penelitian ini adalah rancangan acak lengkap (RAL). Hasil persentase jenis kelamin jantan yang terbentuk diantaranya, pada perlakuan P1 sebesar 88,3%, perlakuan P2 sebesar 95%, P3 sebesar 86,7%. Perlakuan yang tidak menggunakan hormon (kontrol) P0 persentase jenis kelamin ikan jantan lebih rendah yaitu 68,3%. Berdasarkan hasil penelitian yang telah dilakukan dapat disimpulkan bahwa teknik pengalihan kelamin (sex reversal) ke arah kelamin jantan berhasil dilakukan dengan menggunakan hormon metil testosteron melalui perendaman dengan konsentrasi yang berbeda. Perlakuan (P2) dengan pemberian konsentrasi hormon 10 mg/4 liter air cukup efektif untuk memproduksi populasi jantan dengan tingkat keberhasilan mencapai 95%. Kemudian diikuti oleh perlakuan (P1) sebesar 88,3% dan perlakuan (P3) sebesar 86,7 % walaupun berdasarkan uji BNT taraf 5% di antara ketiganya tidak beda nyata.
