Palmaria palmata contains phytochemicals with potential antioxidant properties, such as polyphenols and mycosporins (MAAs). Phycoerythrin and phycocyanin are pigments found in the red algae species Palmaria palmata. It is believed that P. palmata derived silver nanoparticles have excellent antioxidant activity. This study aims to determine the morphological, metabolite profile and antioxidant activity of silver nanoparticle compounds synthesised using P. palmata. The green synthesis of silver nanoparticles was performed using P. palmata as a bioreductant. The morphological characteristics observed were the size and shape of the particles, which were observed using the particle size analyser (PSA) and scanning electron microscopy (SEM). Biochemical characteristics studied were secondary metabolite profiles and antioxidant activity of silver nanoparticle compounds using P. palmata. The metabolite profile was tested using High-Performance Liquid Chromatography (HPLC). The antioxidant activity was tested using the 1,1-diphenyl-2-picrylhydrazyl (DPPH) method with ascorbic acid as the positive control. The study showed that P. palmata AgNPs are spherical, with a size of 185.5 nm. P. palmata AgNP contains phenolic group metabolites of gallic acid at a retention time of 2.74 minutes with a peak height of 89.248 mAu and a relative peak area of 98.73%. The antioxidant activity of AgNP synthesised using P. palmata possesses an IC50 value of 17.113 ± 1.584 ppm, indicating a more robust antioxidant activity compared to the extract of P. palmata, which had an IC50 value of 33.875 ± 11.238 ppm.

This research aims to find out about Hidayatul Mubtadi'in the Islamic boarding school in South Lampung management information system. The availability of a good information system will greatly support educational activities in an institution. The significant developments in information technology have led to fundamental changes, including a large positive impact on increasing productivity and policy formulation of government institutions. A management information system is a system used to present information to support operations, management, and decision-making within an organization. This research employs a survey research method. The data consists of primary data obtained from the head of the Islamic boarding school, the foundation's secretary, teachers, and staff. Meanwhile, secondary data refers to supporting tools or documents related to the research object, such as documents, vision, mission statements, etc. Data collection methods used in this research include observation, interviews, and documentation, and involve data collection, data reduction, data presentation, and conclusion.
