Abstract

The Moringa plant, a tropical species, exhibits prolific growth and is abundantly present in Indonesia and other tropical regions worldwide. An extended lifespan, continuous flowering, and a high tolerance for elevated temperatures characterize it. Utilizing its components, including leaves, bark, seeds, and roots, this multifaceted plant is renowned for its therapeutic properties. The plant's antioxidants and various nutrients, including vitamins and minerals (iron, magnesium, vitamin B6, vitamin B2, vitamin C, and vitamin A), have led to studies on the plant's potential health benefits. In order to develop the local economy in Ulakan village, Padang Pariaman Regency, Moringa plants were processed by using the plant leaves to manufacture herbal tea, which can then be sold. This community service program was significant given the widespread presence and ease of cultivation of Moringa plants within the local region. The program involved the planning and selection of the activity site, the implementation of training sessions, and the assessment of the program's outcomes. The result of this community engagement initiative was the demonstrated interest of many participants in producing Moringa leaf tea.

Abstract

Peat water is one of the surface water sources that is difficult to utilize because it has poor quality with high Organic content (Humic Acid and Fulvic Acid), and Inorganic such as Iron. The application of the Advanced Oxidation Process (AOP) method using an ozone generator can be used in the degradation of peat water, to obtain effective degradation results, a ZnO/Zeolite catalyst is added. This study aims to determine the effect of ZnO/Zeolite catalyst utilization on peat water degradation by Ozonolysis method on Fe, COD, BOD, Nitrite, and Nitrate levels, and TSS values. The parameters tested included determining the optimum conditions for peat water degradation on Fe. The results obtained from the degradation process with ozone is for 15 minutes using ZnO/Zeolite as much as 0.2 grams, peat water sample volume of 20 mL. After the degradation process was carried out at optimum conditions, the Fe content was found to be 0.11 mg/L. The results of the test parameters were within the limits of the quality standards used. Based on these data, it can be said that the decrease in Fe metal concentration values in peat water by ozonolysis is more effective with the addition of ZnO/zeolite catalyst at optimum conditions.

Abstract

Vegetables are food commodities widely consumed by the public due to their high nutritional content. Chili (Capsicum annuum L.), green beans (Phaseolus vulgaris L.), and Chinese cabbage (Brassica pekinensia L.) are among the vegetables that can be processed into various delicious dishes or consumed fresh as raw vegetables. To obtain healthy and high-quality vegetable crops, pesticides are commonly used to control pests that may damage the plants. One of the widely used pesticides is chlorpyrifos, which can leave residues that may pose both acute and chronic health risks. Therefore, it is necessary to analyze the levels of chlorpyrifos pesticide residues in vegetables. The residue levels were determined using a UV-Vis spectrophotometer at a wavelength of 230 nm with dichloromethane as the solvent, while qualitative analysis was performed using HPLC by comparing the retention times of standard solutions and vegetable samples. In this study, washing treatments were applied to the vegetables using dichloromethane, distilled water, well water, and tap water (PDAM) to evaluate the effect of washing on pesticide residue levels. The concentrations of pesticide residues in unwashed vegetables were chili (2.6680 ± 0.0214 mg/kg), green beans (2.4658 ± 0.0193 mg/kg), and Chinese cabbage (2.7950 ± 0.0379 mg/kg). The washing process was carried out three times for each solvent. After three washings using dichloromethane and distilled water, pesticide residues were no longer detected, whereas washing with tap water (PDAM) and well water still left residues, although at levels much lower than the Maximum Residue Limit (MRL). The health risk assessment showed that the aHQ and cHQ values were < 1, indicating that consumption within the recommended limits of these samples does not pose health risks, either in the short term or long term. This study provides important information that repeated washing is necessary to effectively reduce pesticide residue levels in vegetables before consumption.
