Blue swimming crab (Portunus pelagicus) is a sea crab that is widely found in Indonesian waters. One of the determinants of the success of crab cultivation is the availability of quality seeds. Howewer, blue swimming crab hatchery is currently experiencing problems, namely unstable seed availiability due to high mortality and growth at the larvae stage. This research aims to evaluate the effect of various colors of rearing basins of feeding rate and survival rate of blue swimming crab larvae (P. pelagicus) in zoea stage. The larvae for the study was zoea-1 stage with a stocking density of 50 ind/L. The basins used in this study was a round plastic basin with a volume of 40 L filled with 30 L of media water. The feed used was rotifer and artemia nauplius. The method used was a completely randomized design consist of 4 treatments and 3 replications. The treatments that were the use black, green, blue, and red basins colors. The results of the analysis of variance showed that the color of the basins had a significant effect on the feeding rate (p < 0,05) and very significant on survival rate (p < 0,01) for small blue swimming crab larvae were produced in black basins 90.14 and 16.60%.

This research aims was to determine the effect of bokashi dose on plant height, number of tillers, percentage of stems, fresh production, and dry matter production and also to determine the optimum dose of bokashi to obtain the best results on growth and production at the first harvest of dwarf elephant grass. This research was conducted in March 2020 - July 2020 in Sidodadi Asri village, Jati Agung district, South Lampung regency. This research used a Completely Randomized Design (CRD) with 4 levels of treatment, namely P0 (control); P1 (bokashi dosage 30 tons/ha); P2 (bokashi dosage 40 tons/ha); and P3 (bokashi dosage 50 tons/ha). Each experimental treatment unit has plot measuring 2x2 m2. Each trial unit was repeated 3 times, so there were 12 trial units. The data were analyzed by variations analyzed at 5% and or 1% level, after that it was followed by orthogonal polynomial test. The results showed that the dose of bokashi had a significant effect (P<0,05) on plant height, fresh production, and dry production, but had no significant effect (P>0,05) on number of tillers, and percentage of stems. The effect of bokashi fertilizer on plant height was obtained by using the optimum bokashi dose of 36.73 tons/ha and the equation was = 60,13 + 35,38x - 6.62x2 [0 ; 50 ton/Ha] (P<0,01). The optimum dose was not obtained for the number of tillers, percentage of stems, fresh production, and dry production.

Starfruit contains active ingredients such as flavonoids, phenols, antioxidants and vitamin C so that it can be used as an immunostimulant in catfish farming activities. Motile Aeromonas Septicemia (MAS) is one of the obstacles that can cause catfish farming losses. This study aims to determine the effect of differences in timing of feeding containing starfruit juice to protect catfish from MAS disease. The study was designed using a completely randomized design (CRD) consisting of 6 treatments (P) in the form of feeding duration containing starfruit for 7 days (P1), 14 days (P2), 21 days (P3), 28 days (P4). and 35 days (P5) and control of feeding without star fruit juice (P0). The research was carried out at the Aquaculture Laboratory, Sriwijya University. The dose of star fruit juice mixed in the feed is 300 mL.Kg-1 while the catfish used is 8-12 cm in size. The challenge test used Aeromonas hydrophilla bacteria with a density of 108 CFU.mL-1 which was injected as much as 0.5 mL.tail-1 intramuscularly. The results showed that administration containing starfruit juice for 28 days provided the best protection. Based on the hematological test the day before and before infection, the delta decreased the hematocrit by 3% and the delta decreased the erythrocyte count by 3,103 cells.mL-1. In addition, live feed after infection was 100%, prevalence was 17.78% and there was no effect of giving starfruit juice on growth and feed efficiency.

The purpose of this research was to determine the effect of ratio of moringa leaves juice with pineapple juice and the best percentage of arabic gum on the quality of jelly candy. This research was using completely randomized design with two factors, i.e. : ratio of moringa leaves juice with pineapple juice (K): (100%:0% ; 75%:25% ; 50%:50% ; 25%:75% ; 0%:100%) and arabic gum percentage (G): (1,0% ; 1,5% ; 2,0%). Parameters analyzed were moisture content, ash content, vitamin C content, total soluble solid, total acid, lightness value (L*), hedonic organoleptic values of colour, flavour, taste, texture and score organoleptic values of colour and texture. The results showed that the ratio of of moringa leaves juice with pineapple juice had highly significant effect on ash content, vitamin C content, total acid, lightness value, hedonic organoleptic test of colour, flavour, taste and score organoleptic value of colour. The ratio of  moringa leaves juice with pineapple juice (25%:75%) and 2,0% arabic gum percentage produces the best quality of jelly candy based on hedonic organoleptic values of colour, flavour, taste, texture and score organoleptic values of colour and texture.

Dryland area in Indonesia reaches 108.8 millions ha (69.4%) of the total dry land with the potential to expand the area of food crops reaching 7.1 million ha, which is dominated by ultisol and oxisol soil types. Plant constraint cultivation on ultisol soil types is the acidic soil pH with high Al and Fe levels. One of the efforts that can be made to cultivate plants on ultisol soil is the selection of plants that are tolerant of Fe stress. This study aimed to determine a tolerance level and F6 red rice lines that were tolerant of iron (Fe) stress in ultisol soils. The experimental design used was factorial Completely Randomized Design (CRD) consisting of 2 factors, the first factor consisted of 12 treatments (10 test lines and 2 comparison varieties) and the second factor  was iron stress with concentrations (0 ppm and 551,55 ppm). The stress was applied after 3 WAP. The stress resistance test to iron (Fe) should that all lines of red rice F6 on ultisol soils have a score of 1 which indicates the stress tolerance of Fe at a concentration of 551,55 ppm Fe. The 23A-56-30-25-12 and 23A-56-30-25-13 lines were the best lines that were tolerant of 551,55 ppm iron (Fe) stress with the highest growth and yield. The lines tested can be developed on ultisol soils because they are tolerant of Fe.
