Abstract

This study aims to utilize sweet lime leaves, which are only waste that has no value, where sweet lime leaves are one of the ingredients that contain essential oils. Apart from the skin, it turns out that this sweet lime leaf can also be extracted using the Microwave Hydrodistillation (MHD) method. This study uses three variables: the F/S ratios used were 0.375 g/mL, 0.5g/mL, and 0.65 g/mL, the powers used were 150 watts, 300 watts, and 450 watts, and the times used were 30, 60, and 90 minutes. The extraction method uses fresh ingredients with a solvent volume of 200 ml. The test carried out is the GC-MS test. The results of the test method and the purpose of this study were to determine the limonene content in the extraction of sweet lime leaves using the MHD method with variations in ratio, power, and time. The optimum yield of essential oils is at a power of 300 W, 90 minutes, and a ratio of 0.625, with a yield of 0.373%. The most significant components produced in the MHD method of extracting citrus leaves were Germacrene D 29.51%, Alpha-Copaene 18.47%, CIS-CAROPHYLNE 15.42%, 9-Eicosene (E) 8.58% and Limonene 5.51%.

Abstract

This research evaluated the Effect of Hydraulic Residence Time and Organic Loading Rate in a Microalgal Membrane Bioreactor for Wastewater Treatment. One method of treating industrial wastewater combines an anoxic procedure with a Moving Bed Biofilm Reactor (MBBR). In this study, process engineering is combined with microalgae to boost dissolved oxygen levels and counteract the rise in sludge. This study combines process engineering with microalgae to mitigate growing sludge and enhance wastewater quality as measured by dissolved oxygen levels. MLSS 1000 mg/L, Chlorella vulgaris microalgae 106 L, and 1.75 kg of urea and TSP were the microalgae concentrations utilized. The quality of industrial wastewater is positively impacted by adding microalgae in the MBBR process. The quality of industrial wastewater is positively affected by adding microalgae in the MBBR process. Adding microalgae caused the dissolved oxygen level to rise over the minimal threshold. Additionally, when wastewater is being treated, microalgae might lessen the chance of increasing sludge in the MBBR.
