Abstract

Alkaloid compounds are active secondary metabolite compounds produced by plants. These alkaloid compounds provide extraordinary health benefits for humans because alkaloid compounds are efficacious as antidiarrheal, anti-microbial, anti-diabetic, anti-microbial, and anti-malarial. The purpose of this literature review is to describe plants that produce alkaloid compounds as secondary metabolites and their bioactivity as antimicrobials. This literature-based study was systematically carried out to gather, evaluate, and synthesize research results concerning the antibacterial properties of alkaloids and other natural secondary metabolites from plants. The analysis focused on publications from 2015 to 2025, sourced through a structured search in the Medline database using PubMed and Google Scholar. The results of this literature review explain that there are many plants that produce alkaloid compounds as their secondary metabolites. Alkaloid compounds in each plant have the same bioactivity both as anti-fungal and anti-fungal. Alkaloids in their bioactivity will interfere with and damage cell formation in microbes so that microbial growth will be inhibited.

Abstract

Science process skills (SPS) are essential competencies in chemistry learning that support development of scientific thinking and evidence-based problem solving. This study aimed to analyze differences in students' SPS based on gender in chemistry learning at a public senior high schools in Samarinda. The study used a retrospective comparative quantitative approach. The SPS data were collected by using documentation technique involving 65 SPS of eleventh grade students (31 males and 34 females) who programmed chemistry subject. SPS data were analyzed descriptively and inferentially using the Mann-Whitney U test (α = 0.05). The results showed that there was no significant difference in overall SPS between male and female students (p = 0.333) and in most indicators (p > 0.05), except for the observation indicator (p = 0.004), with female students having a slightly higher descriptive mean. These findings confirm that mastery of SPS is more influenced by the quality of the learning process than by gender factors, thus contributing empirically to the application of inclusive science learning oriented towards scientific activities.
