Abstract

This research aims to provide a comprehensive understanding of the photosynthesis process in plants and how environmental factors such as light can be manipulated to optimize plant productivity. The research method used is a qualitative method with four different treatments. The first treatment involves placing Hydrilla plants and water in the sun. The second treatment involved Hydrilla plants and water placed in a dark room. The third treatment used Hydrilla plants and water placed under LED lights. The fourth treatment used Hydrilla plants and water under incandescent light. The results show that the light reaction will affect the rate of photosynthesis. This research uses Hydrilla verticillata plants, water, LED lights and incandescent lights as the main ingredients. The tools used include a glass funnel, 500 cc glass beaker, wire hook, thread, light fitting and test tube.

Abstract

Non-vascular plants, such as mosses (Bryophyta), are commonly found on land. The class of plants known as tuberous plants, or plants that do not have true roots, stems, or leaves as well as xylem and phloem vessels, includes moss plants. Knowing the diversity of moss plants in Namorambe Sub-district is the purpose of this research. On May 9, 2024, this research was conducted by walking around the Namorambe area to look for moss plants that might be there. This research methodology is qualitative, using descriptive and exploratory techniques. This research used observation, documentation, and literature study as data collection methods. Direct investigation into the Namorambe area was used to make observations to identify moss plants. The three species identified based on the results of the identification of leaf mosses around Namorambe Sub-district were Hyophila sp., Pogonatum cirrhatum, and Barbula indica. Leaf mosses were made near people's work areas and were made on tree bark and stone substrates

Abstract

The purpose of this study was to find out how far UINSU biology tadris students know scientific journal articles, and see how far UINSU biology tadris students understand scientific journal article writing. The research method used in this study was descriptive qualitative. The population in this study were UINSU biology students. And the samples in this study were UINSU biology students class 2019-2022, namely 40 students who were still actively studying. The data collection technique used is the survey method. The sampling technique used in this study was random sampling. The data analysis technique was then processed using a descriptive analysis method to find out the results of a questionnaire conducted on Tadris Biology UINSU students class of 2019-2022. The results of this study are based on informants namely students that many students have made scientific journal articles and that means that many students understand scientific journal articles, both in terms of searching for scientific journal articles, understanding scientific journal articles and even making articles. scientific journals. But behind that there are also students, especially in the class of 2022, who still produce few scientific journal articles, and sometimes it's even difficult to find and understand them.
