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

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

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.

Abstract

Aquilaria malaccensis Lamk., one of tree species producing agarwood, has been utilized by the people of Southeast Asia (particularly Indonesia and Malaysia) as a component in traditional medicine due to their phytochemical constituents. This study was carried out to assess acute toxicity of oral administration of ethanolic extract of A.malaccensis (EEAM) using female Wistar rats as model animal. Procedure in accordance with OECD Guidelines for the Testing of Chemicals Test No. 423 with administration dose of 2000 mg/kg bw (single-dose). Parameters observed including signs of toxicity, body weight, body temperature, hematological profile (complete blood count), as well as evaluation of liver function (ALT and bilirubin) and renal function (BUN and creatinine). Data were analyzed statistically based on one-way ANOVA (ɑ=0.05) continued with Duncan's post hoc test (ɑ=0.05) and visualized as line charts. Results showed that neither mortality nor sublethal effects were recorded during 14 days of the experiment. The chart exhibited that the group received EEAM demonstrated a comparable trend to the control group for all parameters. Therefore, it can be concluded that EEAM is safe or no-observed-adverse-effect-level (NOAEL) for single-dose oral administration at the dose of 2000 mg/kg bw. If standardized following the Globally Harmonized System of Classification and Labeling of Chemicals (GHS), EEAM is classified in Category 5 (LD50 > 2000 mg/kg bw). Based on this finding, we will continue to conduct further study to assess the repeated-dose acute oral toxicity of EEAM (subacute period)

Abstract

Catfish (Clarias sp.) aquaculture is a promising sector with high economic potential in Indonesia. However, challenges related to production efficiency and environmental sustainability often hinder its growth. This study investigates the design and implementation of a biofloc system aimed at enhancing catfish (Clarias sp.) aquaculture in Gampong Mata Ie, Montasik, Aceh Besar, Indonesia. The biofloc technology presents a promising solution to the challenges of production efficiency and environmental sustainability in catfish farming by optimizing water quality and maximizing feed utilization through efficient nitrogen cycling. Employing both qualitative and quantitative methodologies, the research involved a comprehensive site survey to assess initial conditions and specific requirements of local catfish farming. The biofloc system design encompassed material selection, pond configuration, and technical parameters such as aeration, water circulation, and organic carbon supplementation. Implementation results demonstrated significant improvements in water quality, with ammonia and nitrite levels maintained within safe limits. Additionally, catfish growth was optimized, evidenced by lower feed conversion ratios, indicating enhanced feed efficiency. From a zoological perspective, the biofloc system provides an environment that closely mimics natural conditions, supporting the welfare of catfish. Ecologically, this technology mitigates negative environmental impacts by minimizing waste and water usage. The application of biofloc technology in Gampong Mata Ie underscores its potential to not only enhance production outcomes but also contribute to local economic and environmental sustainability. This research concludes that the biofloc system design and implementation represent an effective and sustainable strategy for catfish farming, offering significant benefits from both zoological and ecological perspectives. It is anticipated that these findings will serve as a reference for catfish farming developers in similar regions and promote the broader adoption of biofloc technology in the Indonesian aquaculture industry.
