Abstract

This study aimed to investigate the effects of storage time and dilution of black liquor (BL) from Acacia mangium kraft pulping on the characteristics of isolated Lignin. Lignin isolation was carried out by 1 and 2 steps of isolation using HCL 1M to precipitate Lignin, diluted before isolation. Isolated Lignin was analyzed for its acid-soluble Lignin (ASL), insoluble acid lignin (AIL), functional groups by FTIR, solubility in dioxane and NaOH and thermal properties. The effect of BL storage time was also evaluated on the characteristics of the Lignin produced. The results suggest that the longer BL is stored, the higher the lignin yield. When compared to the isolation approach without dilution, the dilution process produced a higher yield and ash content up to 84% and 21%, respectively. Without dilution, the AIL isolated was lower than the dilution during BL storage. The longer the storage duration, the higher the lignin purity. Compared to two-step lignin isolation, dilution treatment in single-step isolation improves yield and purity. The thermal stability of lignin isolation without dilution (184 ⁰C and 167 ⁰C for 1 and 2 steps, respectively) was higher than that of isolated Lignin with dilution (154.8 ⁰C and 160.9 ⁰C for 1 and 2 steps, respectively), according to thermal study. Both lignin isolates with and without dilution have comparable functional groups, as shown by FTIR spectra. Due to the high yield and purity of isolated Lignin, BL dilution could be a viable alternative in lignin isolation from BL. Moreover, the properties of isolated Lignin are also influenced by BL storage.

Abstract

Propolis is a resinous material that bees gather from specific plant exudate streams and utilize to build hives, caulk or seal crevices, create funnels for bees to enter, store honey and pollen, maintain a warm environment, and function as a natural antibacterial. One type of propolis from the Meliponini Tribe, Propolis Homotrigona Apicalis, is made from resin of the damar tree. This research aims to present scientific data on the effects of propolis as an antibacterial in the human gastrointestinal system. The parameters examined included qualitative phytochemical activity, Porphyromonas sp, Steptococcus sp, and Eschericia sp activity as measured by the minimum inhibitory concentration (MIC) using the agar well method on Mueller Hiton Agar (MHA) media, as well as testing for antibacterial potency and comparing its activity to that of a positive chloramphenicol control. Using the cold maceration technique, 96% EtOH solvent was used to extract propolis over the course of three 24-hour periods. Alkaloids, flavonoids, triterpenoids, and carbohydrates were all active, according to the findings of phytochemical tests. According to the findings of the activity test, Porphyromonas sp, Steptococcus sp, and Eschericia sp all exhibited antibacterial activity. Propolis Homotrigona Apicalis has the potential to be utilized as a treatment that treats diarhea, gum inflammation, and bad breath since it has antibacterial action in these areas as well as a healthy digestive system.
