Abstract

Research on the growth potential of the Cempaka Kuning plant (Michelia champaca L) using several sizes of stem cuttings, the aim is to determine the growth potential of the Cempaka Kuning plant using several sizes and shapes of stem cuttings. This research is located in LA Garden Gampong Pango Raya, Ulee Kareng District, Banda Aceh. The parameters observed in this study were the emergence of shoots. The results showed that the Cempaka Kuning plant had a diameterof 0.5 and 1 with the highest number of shoots produced in the D2P1 treatment combination with an average value of 5.5 and the lowest number of shoots wasproduced in the D2P3 combination with an average value of 1.75.

Abstract

Barangan banana (Musa acuminata) belongs to Musaceae family which has hig economic value and has the potential as a commercial material and food diversification. One of the diseases of Barangan banana (Musa acuminata) which causes quite high damage is Fusarium sp. wilt disease. and anthracnose disease Colletotrichum sp. This study aims to control Fusarium sp. and Colletotrichum sp. using ecoenzymes in this study ecoenzymes were made from fruit peel waste which was fermented for three months. Testing the activity of controlling Fusarium sp. and Colletotrichum sp. using the diffusion method. Ecoenzymes phytochemical test results contained alkaloids and saponins. Ecoenzymes at concentrations of 10% - 40% showed strong and very strong activity against Fusarium sp. while Colletotrichum sp. 20% concentration shows very strong activity.

Abstract

Leachate is a liquid containing hazardous materials such as metal Iron (Fe). One method that can be used to reduce Fe levels in leachate is using the bioremediation method. This study aimed to determine the absorption ability of Pseudomonas aeruginosa bacteria in remediating Fe as well as the physical and chemical characteristics of leachate such as COD, TSS, and pH before and after using P. aeruginosa. This study used an experimental method of four treatments and three replications. The concentration of bacteria used was 108 CFU/ml with ex-situ contact times of 0, 10, 20, and 30 hours. The results showed that the highest decrease in Fe, COD, TSS, and pH occurred at 30 hours. The Fe value can be reduced to 4.45 mg/L with an absorption effectiveness of 38.19%; the initial COD value of 1.432 mg/L decreased to 1.301 mg/L. In addition, the TSS value decreased to 213 mg/L from the initial level of 223 mg/L and the highest pH decreased, namely 9.6 to 8.1. The uptake of P. aeruginosa bacteria is good in reducing acceptable levels of Fe and pH.

Abstract

Thermophilic bacteria are a group of bacteria that grow at a temperature range of 45oC to 80oC and have the potential to produce cellulase enzymes. The tourist area of Ie Suum, Aceh Besar District is one of the hot springs in Aceh. This study aims to observe the morphological characteristics, cellulase enzyme potential and activity test in producing cellulase enzymes from thermophilic bacteria found in Ie Suum. The method of isolating thermophilic bacteria uses the pour plate method and testing the cellulase enzyme activity using the DNS (3,5-dinitrosalicylic Acid) method. 15 isolates were obtained, namely 13 Gram positive and 2 Gram negative, 2 genera were obtained, namely the genus Bacillus sp. and the genus Pseudomonas sp. Based on the potential of the cellulase enzyme, the 15 isolates showed the largest clear zone diameter, namely isolate TS6 3,67 cm, isolate TS7 2,33 cm, and isolate TS10 4,00 cm. The results of measuring enzyme activity using the DNS method obtained isolates TS6 4,7 x 10-3 U/mL, isolates TS7 4,4 x 10-3 U/mL, and isolates TS10 5,5 x 10-3 U/mL.

Abstract

Shallot (Allium ascalonicum L.) is a horticultural commodity that has high economic value and is needed every day by the community. Attack by pets and pathogens on shallot cultivation cause a decrease in crop productivity. The pathogen that often attacks shallot plants is Fusariumsp. and Alternaria sp. This study aims to obtain endophytic fungi from shallot leaves that can control Fusarium sp. and Alternaria sp. The endophytic fungus isolation method uses healthy shallot leek samples while the pathogen isolation uses unhealthy leaves. The antagonism potency test was conducted using the dual culture method with an incubation time of 7 days at 25-30oC. Based on the results of the study, there were 4 isolates of endophytic fungi on shallot leaves, namely EA1 isolates (Aspergillus niger), EA2 isolates, EA3 isolates (Clasdoporium sp.) and EA4 isolates (Phyllosticta sp.). The results of the antagonist test showed that the endophytic fungus EA1 was able to inhibit the fungus Fusarium sp. and Alternaria sp. maximally (strong) with an average value of Fusarium sp. of 62.72% while Alternaria sp. 67.83 %. The endophytic fungus EA2 was also able to inhibit both of these pathogens but it was moderately categorized with an average value of Fusarium sp. 52.11 % and Alternaria sp. 53.28%. The mechanisms of inhibition are competition and hyperparasitism.

Abstract

Snacks in the environment around the school freely are a problem that is very risky for biological pollution such as the occurrence of worms due to the presence of bacteria in food which disturbs health a lot. This research was conducted to find out how many snacks containing Rhodamine B are in the lives of elementary school children. Based on the results of the study it was found that only 5 samples showed dark red and purplish colors so that out of 20 samples there were only 5 positive rhodamine B and 15 negative rhodamine B

Abstract

Mahogany seeds contain bioactive compounds such as alkaloids, steroids, saponins, and flavonoids. Flavonoids are useful for reducing fat deposits and cholesterol levels in the blood vessels, while saponins are useful for preventing fat accumulation, improving blood sugar levels, helping increase the immune system. Many people experience unhealthy lifestyle changes, caused by excessive consumption of high-cholesterol foods, irregular eating patterns, and low consumption of fruits and vegetables, which have the potential to cause obesity/obesity. In this study, using mahogany fruit as a weight loss tea (diet). This study applies research with a quantitative approach. The type of research used is experimental. The sample measurement uses the BMI (Body Mass Index) system where to measure the body mass index it can be measured by weight (Kilograms) and height (meters) of the sample. In this study, a sample of UIN ArRaniry students aged around 21 years was used. The results of consuming diet tea for 3 consecutive weeks experienced a weight loss of approximately 1 kilogram per week. Where diet tea is drunk 2 times a day, in the morning and evening. Diet tea is brewed by taking ½ tablespoon of diet tea and brewing it with 200 ml of warm water. The results showed that mahogany seeds processed into tea were effective in losing weight after being consumed for 3 weeks in a row with a decrease of approximately 1 kilogram per day. week, because the mahogany seeds contain bioactive compounds such as alkaloids, steroids, saponins, and flavonoids. Flavonoids are useful for reducing fat deposits and cholesterol levels in the blood vessels. While saponins are useful for preventing fat accumulation, improving blood sugar levels, helping increase the immune system, and slowing the blood clotting process.
