The practical application of waste recycling as feed supplement is potentially required by small-scale aquaculturist. Furthermore, some of the flour derived from waste sea urchin shells and in adopted in feed, including Deadema setosum were evaluated to estimate the effect on white shrimp Litopenaeus vannamei moulting. This research required the experimentation of four doses with triplicate supplementation (0, 2, 4, and 6 g 100 g-1 of feed) on shrimps four times daily (12% of body weight) for 35 days test period. The juvenile specimens, characterized by an initial weight of 1.61±0.11 g, were stocked at a density of 12 individuals in a 12 L aquarium. In addition, four compartments were created in each aquarium to facilitate progress observations. The proximate analysis results showed a 53.76±0.27% calcium content in the shell flour, which significantly increased (P0.05) after higher dose supplementation, in the sequential order 18.65±0.13%, 20.04±0.08%, 23.18±0.10%, and 25.04±0.11%. Moreover, the frequency and moulting interval with 4 g doses (16.59%±0.36% day-1 and 5.91±0.18 days-1) were significant (P0.05) and considered the best, compared to 0 g (10.48% ± 0.24% day-1 and 9.97±0.37 days-1), 2 g (13.49%±0.96% day-1 and 8.10±0.29 days-1), and 6 g (13.81%±0.24% day-1 and 7.90±0.06 days-1). In addition, the respective trend pattern for both parameters increased and decreased at 4 g and 6 g, correspondingly. The highest moulting intensity was also obtained with the 4 g doses, at a range of 4 to 6 times, while the lowest (0 g) varied from 3 to 4 times. These sea urchin shell flour was determined to have numerous practical applications as a feed supplement with proven ability to stimulate moulting in vannamei shrimp.Keywords:MoultingCalciumShellSea urchinFeed supplementationVannamei shrimp

White shrimp (Litopenaeus vannamei) cultivation activities have developed rapidly in Indonesia. White shrimp aquaculture which is carried out intensively with high stocking densities has caused several problems, such as low survival and suboptimal growth. This study aimed to increase the growth, feed conversion, and survival of white shrimp through a combination of probiotics (Lactobacillus sp.) + turmeric flour (Curcuma longa) in feed. The method used in this study was Completely Randomized Design (CRD) with four treatment levels and three replications. The results revealed a significant effect (P0.05) on the value of the daily growth rate (DGR), absolute growth rate (AGR), specific growth rate (SGR), survival rate (SR), feed conversion ratio (FCR), and feed efficiency (FE), but no significant effect (P0.05) on the value of the absolute length rate (ALR). Giving probiotics 10 ml+5 g turmeric flour/kg feed (treatment B) was the best treatment for white shrimp aquaculture, including DGR, AGR, ALR, LPS, SR, FCR, and FE values. Furthermore, the results also revealed that increasing the concentration of turmeric flour in the feed, was negatively correlated to the growth and survival of white shrimp.

Abstract. A meteorological prespective to analyze the Thunderstorm forecasting in Jakarta has been done. The principal indices to be adapted in a fishpond were also arranged in the study. Storms in Jakarta, so-called as Ordinary Cell Thunderstorms, are frequently arose in the afternoon, particularly during transition period on March-May and September-November in which many of them are triggered by different in surface heating. The latter emerged to an atmospheric instability and force the air parcel to rise through the atmosphere. RAOB was employed to the forecasting of Thunderstorm. A number of such indices as K and Showalter indices as well as CAPE are produced and applied to forecast the conditional instability of the troposphere. The result showed that the extension of inversion layer in ~500–300 hPa implied the shrink of humidity and might strength the convective instability. In addition, the higher amount of CAPE proved the maximum velocity of updraft which lead to a strong convection and vertical wind shear during Thunderstorm in Jakarta. On the other hand, based on the storm indices, three principal indices adapted in a fishpond were also arranged i.e. normal, moderate and risk condition.Keywords.

Post-larval snakehead (Channa striata) can be fed on live silkworms (Tubifex sp.), artificial feed and a combination of both as a source of nutrients. The availability of live silkworms depends on the yield in nature. Meanwhile, dried silkworms are available in the market. Therefore, the study to evaluate feeding combinations of dried silkworms and artificial feed for the rearing of post-larvae snakehead was conducted from October to December 2020 in Serang District, Indonesia. The treatments were combinations of dried silkworm and artificial feed at a ratio of 100:0%, 75:25%, 50:50%, 25:75%, and 0:100%, respectively. After being adapted to experimental conditions, post-larvae of snakehead (0.40±0.02 g) were randomly stocked in 15 happas of 50x70x75 cm in dimension size each at a rate of 25 post-larvae and fed on tested diet according to the treatments at 5% of biomass a day, divided into three times for 40 days of experimental periods. The post-larvae of snakehead performed the best growth at the contribution of dried silkworm at 100 – 25%, the best feed conversion and protein efficiency ratio at 100 – 50% and 50%, respectively and the best survival at 50 – 0%. It could be suggested that feeding dried silkworm and artificial feed at a 50:50 ratio, respectively, during post-larvae snakehead rearing.Keywords:Channa striata Feeding combination Nutrient sourcesPost-larvae rearing
