<![CDATA[Sclerotium rolfsii is a fungus that has a wide range of host and high pathogenicity that can cause stem rot, root rot, and wilt in plants. Diseases caused by S. rolfsii can be overcome by using synthetic or chemical fungicides. The use of synthetic or chemical fungicides on an ongoing basis can have a negative impact on human health. Natural pesticides derived from plant leaf extracts are explored to treat plant diseases. One of them is Hyptis suaveolens (L.) Poit. The compounds contained in this plant are alkaloids, flavonoids, tannins, and suaveolic acid. This study aims to examine the effect of H. suaveolens (L.) Poit. extract and the most effective concentration in inhibiting the growth of S. rolfsii. H. suaveolens (L.) Poit. leaf extract was prepared by maceration method using 96% ethanol. The leaf extract solution was evaporated using a vacuum rotary evaporator. The concentration used is 0% (control), 5%, 10%, 15%, and 20% with 4 repetitions. The data obtained were analyzed using one way ANOVA and Duncan test. The results showed that H. suaveolens (L.) Poit. leaf extract could inhibit the growth of S. rolfsii and the most effective concentration was at concentration 15% with 56% inhibition percentage.]]>

<![CDATA[Catfish (Clarias gariepinus L.) is a type of consumption fish from fresh water with elongated body and slippery skin. Efforts to increase catfish cultivation are characterized by high stocking density followed by increased use of artificial feed that is rich in protein. Catfish disease is one of the problems that are often encountered in the effort to enlarge catfish. Therefore, an alternative cure is used with areca leaf liquid fermentation (Areca cathecu L.) and surian leaves (Toona sinensis ROXB.). This study was an experimental study, using a factorial complete randomized design consisting of two factors, namely the dosing factor (A) and the length of the observation day (B). Each treatment was repeated 6 times. The data of this study were analyzed using Analysis Of Variants (ANOVA), the results were significantly different continued using the DNMRT advanced test with a level of 5%. Based on the research conducted, it can be concluded that the use of areca leaf (Areca cathecu L.) and surian leaf (Toona sinensis ROXB.) liquid fermentation influences the wound healing in catfish (Clarias gariepinus Var.) and the most optimal dose to assist the healing process is at a dose of 15 ml.]]>

<![CDATA[Betta fish (Betta splendens Regan.) Is an ornamental fish that has high economic value because of the beauty of color and its fighting instincts. . However, fans of ornamental fish prefer male fish than females because male fish have better and more attractive aesthetic and color values and have higher profits. There are two non-parasitic diseases that commonly attack Betta fish, namely bite the tail and bruising. During this time the treatment used always uses chemicals such as PK solutions, methylene blue and melachite green. The use of chemicals does not always have a positive effect but can also have a negative impact on non-targeted organisms. Another effort taken to treat this disease is to use natural ingredients, namely by using fermented liquids from areca leaves and surian leaves. Medicinal plants or plants can be obtained by fermentation. Areca leaves and surian leaves are capable of producing secretions of secretive drugs. The test results of organic compounds of fermented liquid areca leaves and surian leaves containing antibiotics and other organic compounds that work synergistically accelerate healing and relieve pain or pain due to injury to the culture. This study was an experimental study, using a factorial complete randomized design consisting of two factors, namely the dosing factor (A) and the length of the observation day (B). Each treatment was repeated 6 times. Data were analyzed using Analysis Of Variants (ANOVA), the results were significantly different followed by continued testing of DNMRT level of 5%. Based on the research conducted, it can be concluded that the administration of fermented areca leaves (Areca catechu L.) and surian leaves (Toona sinensis ROXB.) Affects wound healing in Betta fish (Betta splendens Regan.) And the fastest treatment to help wound healing process that is on treatment A3 with a dose of 15 ml. ]]>
