“…Penelitian ini bertujuan menganalisis kinerja zat warna alami senyawa antosianin selada laut melalui celah energi optiknya. Selada laut dipilih karena belum pernah dilakukan penelitian sebelumnya dan terdapat kandungan senyawa antosianin [14]. Selain itu selada laut sangat mudah ditemukan di Indonesia khususnya di Pulau Bali.…”

The optical energy gap of anthocyanin compounds from sea lettuce extract (Ulva lactuca L.) has been calculated using the Tauc plot method. Sea lettuce plants taken at Sanur Beach Bali. The sea lettuce was dried then mashed and extracted for 24 hours, the last being macerated through three cycles. The extraction results are then evaporated to obtain a thick extract solution. Extracted and evaporated-extraction samples were characterized by UV-Vis in the wavelength range of 200-800 nm. From the characterization results, it was found that the absorption of anthocyanin compounds for the extracted samples was at a wavelength of 268 and 412 nm. Meanwhile, for the extraction-evaporation sample, the absorption is at a wavelength of 286.5 and 408 nm. By using the Tauc plot method, the optical energy gap values ??for the extracted and extraction-evaporated samples were 2.69 and 2.54 eV, respectively. Therefore, anthocyanin compounds from both extracted and evaporation-extracted samples qualify as dye sensitized solar cells (DSSC) for TiO2 semiconductors.

“…Selain itu, ekstrak Ulva lactuca juga meningkatkan aktivitas enzim antioksidan dan mengurangi peradangan pada ikan (Akbary & Aminikhoei, 2018;Domínguez & Loret, 2019;Mahasu et al, 2016;Nurfadillah et al, 2021;Tong et al, 2020). Selain kandungan polisakarida, Ulva lactuca juga mengandung berbagai senyawa fitokimia seperti polifenol, flavonoid, dan karotenoid, yang memiliki aktivitas antioksidan dan anti-inflamasi yang kuat (Windyaswari et al, 2019).…”

Produk perikanan makin meningkat dari tahun ke tahun. Namun, seperti kegiatan pertanian lainnya, akuakultur juga dihadapkan pada berbagai tantangan, termasuk munculnya penyakit dan stres yang dapat menurunkan kualitas dan kuantitas produksi (Walker & Winton, 2010). Sebagai respons, beberapa pembudi daya mungkin telah mengandalkan penggunaan bahan kimia seperti antibiotik, hormon pertumbuhan, dan pestisida untuk meningkatkan produktivitas serta mengendalikan penyakit pada ikan budi daya.

“…The extract produced will increase if the boiling time is longer; therefore, the amount of rosmarinic acid will be affected, too. However, the longer the boiling time, the longer the plant will experience contact with hot temperatures, which can cause compound degradation and reduced compound stability, so the levels of extracted secondary metabolites will decrease [17][18][19]. The reason for choosing this boiling method is because of the polarity of rosmarinic acid, which is polar and can dissolve in water because it has one carboxylic group and four hydroxyl group.…”

Objective: Determine the best time to boil cat whiskers by observing the impact of boiling time on the quantities of rosmarinic acid in cat whiskers. Methods: For the extraction process, water is boiled for 10, 20, and 30 min at 90 degrees Celsius. High-Performance Liquid Chromatography (HPLC) was used to measure the quantities of rosmarinic acid and validate the analytical procedures in terms of accuracy, precision, linearity, and specificity. The one-way ANOVA test and Duncan's test were used to analyse the data; a p-value of 0.05 was used to indicate a statistically significant difference. Results: The lowest quantities of rosmarinic acid were found in the study's results during a shorter boiling duration of 10 min, or 2.07% w/w. The highest concentrations of rosmarinic acid were found after a prolonged boiling period of 20 min, at 2.32 % w/w. Meanwhile, rosmarinic acid levels dropped to 2.15 % w/w after a 30 min overboiling period. Rosmarinic acid levels from the three boiling durations differed significantly, according to statistical analysis (p=0.000; p<0.05). Conclusion: It was determined that 20 min was the ideal boiling duration for extracting rosmarinic acid from purple cat whiskers.
