Abstract. Cokrowati N, Risjani Y, Firdaus M, Andayani S. 2021. Accelerated growth of Kappaphycus alvarezii using Sargassum aquifolium extract and its anatomical characteristics. Biodiversitas 22: 5195-5202. Cultivation of Kappaphycus alvarezii seaweed has been carried out in Ekas Bay of Jerowaru Sub-district, East Lombok, West Nusa Tenggara, Indonesia but its production has decreased in the last three years due to its slow growth. In 2014, seaweed production was 1,882,875.50 tons and in 2017 it was 1,037,000 tons. Efforts are needed to increase growth by providing growth triggers from marine natural ingredients, namely Sargassum aquifolium. These brown algae can be found in the waters of Ekas Bay, the numbers are abundant and untapped. The purpose of this study was to analyze the growth of K. alvarezii given S. aquifolium extract. This research was conducted in the waters of Ekas Bay. The method used is experimental. The experimental design used was a completely randomized design with different treatments of K. alvarezii soaking time using S. aquifolium extract. The results showed that the growth of K. alvarezii given S. aquifolium extract increased and was significantly different between treatments. The highest absolute weight was 479 g in treatment A (soaking for 2 hours) and the lowest absolute weight was 181.25 g in treatment K (control). The highest growth rate occurred on the 18th day, namely 9.24% and the lowest was in the K treatment (control) which was 1.3%.

ABSTRACT The aim of this study was to analyze the potential use of açaí seeds as an alternative ingredient in the feed of slow-growth broilers until 28 days of age. We carried out a bromatological analysis of fractions of the açaí fruit. The açaí seed without mesocarp was the best choice for formulation of the açaí seed bran (ASB), which was evaluated in terms of bird performance and economic viability of the supplemented feed. A total of 416 male chicks of the French Red-Naked Neck lineage were used in a completely randomized design with four treatments (0, 2, 6 and 10% inclusion of ASBin the feed) with eight replicates each. The results indicated that ASB can be included in proportions of up to 10% in the diet of slow growth broilers at early development stage without impairing performance. The 10% inclusion level also was economically equal to the control treatment, representing a viable alternative for broiler production, with potential for reduction of the negative impacts generated by açaí residue in the environment.

One of the difficulties of producing native species seedlings is slow growth. The objective of this study was to evaluate the initial development of Amburana cearensis (Allem.) A. C. Smith in relation to the concentration decomposed buriti stem substratum and nitrogen doses. A completely randomized design was used in a factorial arrangement of 3 × 5 (proportions of decomposed buriti stem × nitrogen doses), with six replicates. The treatments were formulated substrates comprised of decomposed buriti stem manually mixed with soil (Dystrophic Yellow Latosol) in three proportions (0, 25 and 50%) and five nitrogen doses (0, 100, 200, 300 and 400 mg dm-3) applied in treatments. There was no significant interaction between the DRM and ND factors. However, there was an isolated effect for the following variables: Plant height (PH), stem diameter (SD), leaf number (LN), leaf area (LA), dry mass of the aerial part (DMA) and root length (RL). The best concentrations of the substrate for the variables PH, LA and DMA were 25% and 50%, whereas for SD, LN and RL, the best result was 50%. ND and other variables had good responses under recommended doses ranging from a minimum of 264.82 mg dm-3, observed in DMA, and a maximum of 400 mg dm-3, observed in RL. Both factors positively the quality of umburana seedlings.
