This study aimed to determine the effect of immersion of hybrid duck eggs using guava leaf extract at different concentrations on embryo mortality, hatchability, and saleable duck. The research was conducted in March - April 2020. Guava leaf extract was made at the Animal Production and Reproduction Laboratory, Department of Animal Husbandry, Faculty of Agriculture, University of Lampung. The dyeing and hatching treatments were carried out in Hajimena Village, Natar District, South Lampung. This study used a completely randomized design (CRD) with four treatments, namely without immersing guava leaf extract (P0), immersing with guava leaf extract concentrations of 10% (P1), 20% (P2), and 30% (P3). The results showed that the percentage of embryo mortality without dyeing and immersing guava leaf extract concentrations of 10, 20, and 30% were 40.00%, 24.00%, 16.00%, and 28.00%, respectively. Hatchability of hybrid duck eggs in the treatment without immersion and immersion in guava leaf extract concentrations of 10, 20, and 30% were 60.00, 76.00, 84.00, and 72%, respectively. Saleable duck duck eggs without immersion 93.34% and immersion in guava leaf extract with concentrations of 10, 20, and 30% respectively were 100.00%. It was concluded that immersion of hybrid duck eggs using guava leaf extract at concentrations of 10.00, 20.00, and 30.00% decreased the percentage of mortality, increased hatchability, and increased the salable duck.

Guava leaves can be used as a natural preservative in quail carcass because they contain antimicrobial compounds such as flavonoid and tannin. This study studied the effect of using guava leaves infusion on quail carcass on the total bacteria, Enterobacteriaceae, and early spoilage.  The research used an experimental method with a completely randomized design, 3 treatments of guava leaves infusion concentration, namely P1 = 25%, P2 = 50%. And P3 = 75%, each treatment was repeated 6 times.  The application of infusion to quail carcass was carried out by immersion for 15 minutes.  Data were analyzed using ANOVA and Turkey’s test.  The results showed that the total bacteria and Enterobacteriaceae before immersion were 3.80 x 107 cfu/g and 1.90 x 104 cfu/g, respectively.  Soaking quail carcass in guava leaves infusion was able to reduce the total bacteria and Enterobacteriaceae to 72.15% and 78.50%, respectively.  The early spoilage was inversely proportional to the total bacteria and Enterobacteriaceae resulted in longer shelf life.

Fish is kinds of food that easy to spoil. High protein content in fish makes the food is a good medium for microorganisms. People commonly buy fish for consumption, however, not all fish are consumed at the same time. Fishes were stored in freezer for several days or preserved with additional chemical preservation. The use of organic preservatives have no harm. This paper discussed guava (Psidium guajava L) leave as natural fish preservation. The objectives were to analyze the potency of the leaves as a natural preservation for mackerel fish (Rastrelliger sp.). Fime parameters used to determine the fish quality as follows : gills, eye, texture, odour and mucilage. The treatments were leaf methanolic extract with doses 0, 20, 40, 60 and 80%. Data were taken on from 1 to 5 days after storage. The results showed that (i) Fish quality was decline and start to depraved at 2 day storage, especially at control treatment (0% extract). Treatment at doses 60 and 80%, the fish quality were still relatively good over 3 days storage. Even though the fish samples have been starting spoilage, those fishes were still available to be consumed. At the same time, with the other treatment, the fish samples have been spoiled and no more available to be consumed. However, at 5th day of storage, all samples at all treatments were spoiled. Overall results, it can be concluded that extract of guava leaves can be has as fish preservativedosage

Mojosari x Alabio (MA) ducks have several advantages including higher egg productivity, early age of egg laying, faster growth, better production consistency, compared to its parents. The bay plant is scientifically named Latin Eugenia polyantha Wight. Bay leaves contain phenolic compounds, saponins, alkaloids, flavonoids and steroids. This study aims to determine the effect of giving bay leaf extract in drinking water on the percentage of giblet and mojosari alabio duck digestive apparatus.  The research was carried out in the cages of the Animal Husbandry Study Program, Faculty of Agriculture, University of Djuanda, Bogor, from March to May 2019. The cattle used in this study were 100 mojosari alabio (MA) ducks aged 1 day which were kept until one week old (adaptation period).  This study uses a completely randomized design (CRD) consisting of 5 replications and each repetition consists of 5 ducks. The treatments in this study consisted of 4 treatments: R0 = 0% bay leaf extract (control), R1 = 4% bay leaf extract, R2 = 8% bay leaf extract, R3 = 12% bay leaf extract.  The data obtained were analyzed using the Analysis of variance (ANOVA), the results data were significantly different (P <0.05) followed by the Duncan test. The variables observed in this study were: giblet weight and digestive organ weight. The results showed that giving of bay leaf extract had no significant effect (P <0.05) on the observation variables. The conclusion of this study is the provision of bay leaf extract in drinking water up to the level of 12% has an impact on the percentage of gizzard and pancreas at the age of 6 weeks. At the age of 8 weeks no effect on the percentage of giblets and the percentage of digestive organs of mojosari alabio ducks. It is recommended to give bay leaves in the form of flour with a level higher than 12%.Keywords: bay leaf extract, mojosari alabio duck, giblet percentage, digestive organ percentage.

The aim of this research was to evaluate the effects on the growth of Staphylococcus Aureus bacteria in vitro of antibacterial activity of guayava leaf extract (Psidium guajava L.) and guavava leaf extract impact on the growth of staphylococcus Aureus bacteria at different laboratory concentrations. In this experiment, S. Aureus bacteria are being treated to guava leaf extract to identify the lowest inhibitory power for well techniques, and the results have been recorded. The Guava leaf extract (Psidium Guajava L) against Staphylococcus aureus was found to have an inhibitory zone diameter of mm in the absence of tetracycline, and DMSO as a negative control. Findings were observed using the disk diffusion technique or paper disc with concentrations of 1 percent, 3 percent, 5 percent, and 7 percent. Saponins, saponins, alkaloids, and flavonoids found in guava leaves are responsible for their antibacterial effects. Saponins have the potential to disturb the integrity of bacterial cell membranes. This results in bacterial cell membrane destruction, releasing essential components from the cell

<h1>Spodoptera litura F. is one of the important pests in Horticulture commodities which can cause damage 80% and up to 100%. Karamunting (Melastome malabathricum) is a wild plant that grows in Tarakan City. This plant is known to contain secondary metabolites which are thought to have the potential to control pests. This study aims to determine the potential of Karamunting extract as a botanical insecticide material to control armyworms. This study uses a completely randomized design (CRD) method with 1 treatment factor, namely the concentration of Karamunting leaf extract. Potential extracts as botanical insecticides were tested by dye method using 4 concentrations, namely 0 (control); 500; 1000; 2000; 4000; and 8000 ppm. The results showed that Karamunting leaf extract was able to control armyworm pests. Giving extracts of 8000 ppm (P5) in feed caused the highest decrease in eating activity up to 41,2%, larval mortality up to 85%, and the highest mortality rate after 7 days of observation. Decreased feeding activity and larval mortality were thought to be influenced by the presence of phenol compounds, fatty acids, terpenoids, sterols and alkaloids identified in the extract. Thus, Karamunting leaf extract has the potential to be developed as an active ingredient in botanical insecticides to control armyworm.<strong></strong></h1>
