This study aimed to evaluate potential biogas production from Ludwigia hyssopifolia (water primrose) and examine the effect of alkaline pretreatment on samples through biogas production efficiencies. The research was carried out for 45 days of operation from anaerobic mono-digestion of water primrose by using a batch experiment. Pretreatment was applied for substrate using sodium hydroxide (NaOH) solution (w/v) at different concentrations (0, 1, 2, 3, and 4%) with 10% of total solids (TS) based on dry matter. The scanning electron microscopy (SEM) images were captured to investigate the characteristics of the raw material and pretreated biomass. The results showed that the treatment with 2% NaOH has the highest performance in biogas yield (8072.00 mL) and methane content (64.72%). Notably, the increase (3, 4%) or decreasing (0, 1%) NaOH concentration in treating water primrose did not achieve a significant improvement. Further investigation in the power potential of produced biogas was calculated, and the result was 22,382.19 W/m³ power. Consequently, the feasibility of the alkaline pretreatment method for biogas production and achievable potential for energy efficiency indicates that water primrose is appropriate agro-weed biomass for bioenergy applications.

这项研究旨在评估潜在的Ludwigia hyssopifolia沼气生产（月见草水）并通过沼气生产效率检查碱性预处理对样品的影响。使用分批实验，从厌氧消化月见草的整个过程中进行了45天的研究。使用不同浓度（0、1、2、3和4％）的氢氧化钠（NaOH）溶液（w / v）对基质进行预处理，以干物质计占总固体（TS）的10％。捕获扫描电子显微镜（SEM）图像以研究原材料和预处理过的生物质的特性。结果表明，用2％NaOH处理的沼气产量（8072.00 mL）和甲烷含量（64.72％）最高。值得注意的是，在处理水樱草花中增加（3，4％）或减少（0，1％）NaOH浓度并没有取得明显的改善。³电源。因此，碱性预处理方法用于沼气生产的可行性和可实现的能源效率潜力表明，报春水是适合生物能源应用的农用杂草生物质。
