Conjunctivitis is inflammation in the conjunctiva, with clinical signs of exudation, cellular infiltration, and vascular dilatation. In adults, Staphylococcus species are the most common pathogenic bacteria resulting in bacterial conjunctivitis. Previous studies in vitro, explaining that mulberry leaf extract can inhibit the growth of S. aureus bacteria. The purpose of this study was to investigate the effect of mulberry leaf ethanol extract (Morus alba L.) on wistar mice conjunctivitis model by S. aureus. This type of research is true experimental with pretest-posttest control group design. The 24-wistar mice were adapted for 7 days. On day 8, a conjunctivitis induction was performed with 1.5 x 108 CFU / ml of S. aureus at 1 drop every 10 minutes for 1 hour (left 3 days) until conjunctivitis . On day 12 until day 19 (7 days), given mulberry leaf extract 45%, 55%, 65% and 75%. The results of TPC S. aureus logarithm on MSA medium of the 11th (pretest) day conjunctival swab and the 17th day (posttest) of rat adaptation were K (-) (5.70 and 4.07); K (+) (5.78 and 3.31); P1 (5.65 and 3.78); P2 (5.63 and 3.82); P3 (5.84 and 3.74); and P4 (5.69 and 3.63), with the posttest group there was improvement in conjunctivitis symptoms rather than the pretest group. The result of One Way Way Anova data analysis showed significant result at pretest p = 0,002 and posttest p = 0,046 (p <0,05) and paired t-test got significant result p = 0,000 (p <0,05). From this study it can be concluded that mulberry leaf extract (Morus alba L.) has the effect of decreasing the number of colonies of S. aureus bacteria and improving symptoms of conjunctivitis.

This study used 1,500 quail hatch eggs with a male and female parent ratio of 1: 4. This study used a Completely Randomized Design (CRD) method, with five treatments and three replications each repetition consisting of 100 quail eggs with 10-gram weight. The treatments used were: T0 (control treatment), T1 (commercial disinfectant), T2 (noni leaf extract 10%), T3 (noni leaf extract 20%) and T4 (noni leaf extract 30%). The results of variance showed the average percentage of hatchability produced during the study, namely T0 (85%), T1 (83%), T2 (86%), T3 (84%), and T4 (93%). Furthermore, the average weight of hatchability produced, namely T0 (6.67 grams), T1 (6.76 grams, T2 (6.89 grams), T3 (6.84 grams) and T4 (6.89 grams). Overall administration of noni leaf extract had no significant effect (P> 0.05) on the percentage of hatchability and DOQ hatching weight of the quail.

Mulberry Leaf Extract

Mulberry (Morus alba L.), and above all the extract from the leaves of this plant, is a natural medicine that has been used in traditional medicine for hundreds of years. Mulberry leaves contains polyphenol compounds: flavonoids, coumarins, numerous phenolic acids, as well as terpenes and steroids. The antioxidant effect of these compounds may be beneficial to the fat fraction of meat products, thereby increasing their functional qualities. The aim of the study was to evaluate the effectiveness of the use of mulberry water leaf extract, as an additive limiting adverse fat changes and affecting the functionality in model liver pâtés. Pork pâtés were prepared by replacing 20% of animal fat with rapeseed oil (RO), and water extract of mulberry leaves was added in the proportion of 0.2%, 0.6% and 1.0%. It has been shown that the addition of mulberry leaf extract delayed the appearance of primary and secondary fat oxidation products. The most effective antioxidant effect during 15-day storage was observed in the sample with the addition of 0.6% and 1.0% water mulberry leaf extract. These samples also showed inhibiting activity against angiotensin-converting enzymes and cholinesterase’s. During storage, the tested pâtés had a high sensory quality with unchanged microbiological quality. Mulberry leaf extract can be an interesting addition to the production of fat meat products, delaying adverse changes in the lipid fraction and increasing the functionality of products.

In terms of control, various natural chemical compounds derived from plants can be used. Like papaya and soursop leaves, the formulation of the problem is whether the combination of soursop leaf extract and papaya leaf extract is effective in controlling S. litura pests and what is the most effective extract concentration. This study used a completely randomized design (RBD) with 5 treatments and 5 replications. Observation variables included symptoms, morphological changes and mortality, the results were analyzed by Analysis of Variance (ANOVA) followed by the Least Significant Difference (LSD) 5% test. The initial symptoms that were seen one day after application of the combination were morphological changes in the test larvae. Such as damage to the body of the larva, change in color, then the larva's body shrinks, when touched the larvae easily fall. The highest mortality was found at the extract concentration of 20% with a mortality rate of 64.79% on the second day. The results showed that the high mortality rate was closely related to the high toxicity contained in the 20% extract concentration. It was concluded that the results of the effectiveness test of the combination of papaya leaf extract and soursop leaf extract were effective. Suggestions for the use of natural materials that are easily available can be used as an alternative to control pests that are environmentally friendly. Furthermore, it is suggested that if you want to increase mortality, you can try increasing the extract concentration.

Cataract is a degenerative disease and one of the leading causes of blindness in Indonesia and in the world. Free radical formation leads to pathological reactions in the lens that can induce lipid peroxidation that produces malondialdehyde (MDA). Mulberry leaf (Morus alba L.) is one of the plants rich in antioxidants. The purpose of this study was to determine the effect and effective dose of mulberry leaf extract on MDA content of eye lens in rats cataract model. This study is true experimental with posttest only control group design. This study used 7 groups, each 5 tails. Normal control groups were not treated. The negative control group induced sodium selenite 25 μmol / kgBW and was given 0.1% HPMC eye drops. The treatment group induced sodium selenite 25 μmol / kgBB and given 0.05%, 0.1%, 0.2%, 0.3% and 0.4% mulberry leaf extract for 14 days. Measurement of MDA lens concentration are using MDA-TBA method. Data analyzed by using one way Anova test showed significant result with value p = 0,000 (p <0,05). Based on the results of this study it can be concluded that mulberry leaf extract has an effect on decreasing MDA lens in rats cataract model. Among the concentrations used, the concentrations that showed the lowest decrease in MDA concentration were 0.4%.Keywords: cataract, sodium selenite, malondialdehid, Morus alba L
