Abstract

A new variant of the SARS-CoV-2 virus (i.e., B.1.1.7) has been found in Indonesia. The lack of information regarding this new variant may cause public concern. This literature aimed to provide knowledge regarding variant B.1.1.7, sourced from the following databases: Science Direct, PubMed, Semantic Scholar, and Google Scholar. This literature described the chronology of the discovery of variant B.1.1.7, all occurred mutations (especially in spike proteins), and the impact of these mutations on virus characteristics. This paper also explained the effectiveness of the vaccines circulating worldwide and the development efforts that had been carried out. Besides that, the latest information on surveillance efforts to improve the efficiency of virus detection and prevent the spread of the SARS-CoV-2 virus, either variant B.1.1.7 or other variants, was also reported.

Abstract

Each processing palm fresh fruit bunches (FFB) into Crude Palm Oil (CPO) will produce solid and liquid waste. One of the forms of liquid waste produced is Palm Oil Mill Effluent (POME). POME waste can cause problems for the environment because it has physical characteristics of dark brown color, high density, rich in organic matter, and bad smell. The POME waste color is thought to come from melanoidin, a biopolymer pigment produced by the Maillard reaction of coconut processing. Apart from melanoidin, phenolic components are detected in POME waste, where this group of compounds is toxic. Several studies have shown that Lactobacillus plantarum can reduce the color of POME by 75%. The decolorization process is thought to involve an enzyme as a waste color-changing agent. However, the efficiency associated with these events has not been further investigated. There are three main methods of melanoidin degradation, such as biological, physicochemical, and enzymatic. This study uses the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyzes) approach in creating a short, concise, and clear summary through various references.
