Sweet Potato Leaves

In aquaculture, fish health problems are often encountered which can lead to failure in cultivation activities. One of the efforts to overcome the problem of disease in cultivation is done by providing immunostimulants. Sweet potato leaves (Ipomoea batatas) are plants that have a short harvest period, cheap and rich in vitamins and antioxidants so that it can be used as a source of immunstimulants. This research was conducted to determine the effect of adding sweet potato leaves (Ipomea batats) to tilapia (Oreochromis niloticus) feed on total leukocytes, phagocytic activity, hematocrit, and survival rate. The study was conducted by experimental method using a completely randomized design, with 4 treatment doses of sweet potato (Ipomoea batatas) used were 0%, 5%, 10% and 15%, which were formulated in fish feed and each treatment was repeated 3 times.. The results showed that giving 10% of sweet potato (Ipomea batatas) leaves in feed had a significant effect on the non-specific immune system of tilapia, which could increase the highest total leukocyte value by 6600 mm3 but did not have a significant effect on the phagocytosis index. 96.3%, 31% hematocrit with 93% survival.

White sweet potato starch (Ipomea batatas L.) and avocado seed starch (Parsea americana Mill) derived from local plants have the potential to be developed as agricultural products. Starch is a hydrocolloid compound as a potential local resource to be utilized. Glycerol function as an anti-freezing which is hygroscopic. This study aims to determine the ratio of white sweet potato starch with avocado seed starch and the concentration of glycerol for making edible film. This study was an experiment using a completely randimized factorial design with 2 (two) main factor consisting of a comparison of white sweet potato starch and avocado seed with 3 levels: P1 = 35%:65%., P2=50%:50%., P3=65%:35% and glycerol concentration with 3 levels: G1=1%., G2=2%., G3=3%. The best result reasearch were content of 23.03% (tratment P1G1), solubility of 55.57% (treatment P3G2)., swelling test of 9.83% (treatment P2g3)., elongation of 8.18% (treatment P3G2)

Delonix regia is commonly called Flamboyant or flame of the forest. The seeds were fermented, boiled, sundried and then ground into powdered meal. 40% crude protein based test diets containing Delonix regia seed meal D0 = 0%; D15 = 15%; D20 = 20% and D25 = 25% inclusion levels respectively were prepared. Red tilapia (Oreochromis niloticus) fingerlings of 6 weeks old were acclimatized for two weeks and then stocked in 12 hapas at 15 fish per hapa measuring 0.6 m × 1.2 m × 0.7 m placed in a concrete tank. Each diet was assigned to fish in a separate hapa in triplicate and administered at 3% fish body weight per day for 16 weeks. Fish weight and length were taken initially, bi-weekly and terminally. Water quality was monitored weekly. Number of fish at the end was recorded and survival rate, growth, feed utilization, fillet yield and blood parameters were determined. The data were subjected to the analysis of variance and mean separation (P= 0.05). Survival rate was highest in fish raised on D20 and least in D25 without any significant difference across the range. Mean growth performances, feed utilization indices and fillet yield were generally congruent between D20 and D25 with varying degrees of significant difference to other feeds. Results of blood assay did not depict harmful effects of the test diets indicating that the fish enjoyed some good measures of health. The gross performance of fish on D20 was optimal. It was therefore concluded that 20% dietary inclusion level of fermented, cooked and dried flamboyant seed was the best for the red tilapia (Oreochromis niloticus) post fingerlings.
