Abstract

This study aimed to demonstrate simple classroom experiments by evaluating the phytochemical components of the extracts of weed (Eleusine indica). The purpose of this study is also to contribute effective use of natural resources in the locality by transforming traditional knowledge to the scientific way of using the medicinal plant to be used as raw materials in pharmaceutical industries. The weed was air-dried for ten days. It was then pulverized using an electric blender. The mixtures were allowed to stand for seventy-two hours to extract the bioactive components of the weed. The experiment used chloroform (polar) in extracting the secondary metabolites present in the weed.   The mixtures were then filtered with a cheese cloth and concentrated in direct heat using a hot plate. The extract was placed in a beaker and was labelled as chloroform extract. The bottle was covered tightly to prevent evaporation of the solvent. The Phytochemical components present in the weed extracts were alkaloids, flavonoids, carbohydrates, diterpenes, and saponins. This study is expected to be one of the teaching model (since the experiments are simple). This study also is expected to identify the phytochemical components of weed, identify the phytochemical components of weed, and contribute to the effective use of natural resources.

Abstract

Choosing a senior high school strand is one of the most challenging decisions that junior high school students will have to face. The study aimed to help students decide on their future senior high school strand by knowing the factors’ influence levels and their relationship with their decision. The survey was conducted online (Grade 9 and Grade 10 students) using the total sampling method. We employed a self-made questionnaire that went through content validation using Aiken’s V formula. Descriptive statistics were then used to analyze and interpret the results of the study. In the survey’s results, 2.3% of the students chose GAS as their senior high school strand, 15.9% chose HUMSS, and 73.9% chose STEM, leaving the ABM strand with 8%. The personal interest factor had the highest level of influence among the factors, with a mean of 4.21, followed by job opportunities with a mean of 4.17, socioeconomic status with a mean of 3.89, parents with a mean of 3.63, and academic performance with a mean of 3.38. However, in terms of the factors’ significant relationships with the senior high school strands, socioeconomic status, parents, job opportunities, and personal interests were found to have no significant influence when deciding, and academic performance is the only factor that has a significant influence on the students’ preferred strand. As a result, the null hypothesis of the study is accepted because only one out of five factors were found to have a significant relationship when deciding on a senior high school strand.
