Pengaruh Limbah Cair Pabrik Kelapa Sawit Terhadap Kandungan Protein, Karbohidrat, Dan Bioetanol Pada Lemna Perpusilla Di Science Techno Park Kecamatan Siak Hulu Kabupaten Kampar Riau

Liquid waste from palm oil mills has a fairly high nutrient content and can be used as organic fertilizer for the growth of Lemna perpusilla. Lemna perpusilla known as aquatic weed with its proximate content can be considered as bioethanol. To determine the effect of utilizing palm oil mill liquid waste on the proximate and bioethanol content of Lemna perpusilla, a study was conducted from February-May 2024. This study used a Completely Randomized Design (CRD) with 4 treatments, P0 (without waste), P1 (15% waste), P2 (25% waste), and P3 (35% waste) with 3 replications so that a total of 12 experimental units. Parameters measured during the study included the biomass of Lemna perpusilla, temperature, and pH, which were monitored over a 15-day period at 3-day intervals. Nitrate and phosphate concentrations were measured at the beginning and end of the study. Proximate analysis (protein, carbohydrate, and moisture content) and bioethanol measurements were carried out on the two best-performing treatments of Lemna perpusilla. The results showed biomass ranging from 10,00-31,45 g, nitrate concentration from 1,252-0,208 mg/L, phosphate concentration from 1,297-0,317 mg/L, temperature ranging from 29-30°C, and pH ranging from 6-9. The data indicated that the application of palm oil mill effluent affected the biomass of Lemna perpusilla, with the best result observed in treatment P1. Protein content ranged from 2,89-3,83%, carbohydrate content from 7,18-7,74%, and ethanol content from 19,20-20,00%. Based on its ethanol content, Lemna perpusilla is not considered a viable source for bioethanol fuel production.
