The intensity of light will affect the physiological processes of the plant. When the light intensity is high, the leaf cells will be smaller, the amount of chlorophyll is less, and the thylakoids in the leaves clump so that this can affect the growth of mung bean plants. In order to compare the growth in a bright environment with the growth of green beans in a dark environment, this research on the advantages of the influence of sunlight on the germination process of green beans was conducted. Plants must have access to light in order to complete the process of photosynthesis. Because light interferes with the function of the growth hormone (auxin), plants that receive more light from the environment experience growth inhibition, resulting in shorter stems than plants that receive less light.

The epidermis is the layer of cells on the outside and covers the surface of
leaves, flowers, fruits, seeds, stems and roots. The function of the epidermis is
to protect the internal organs of the plant. Based on its function, the epidermis
can develop and undergo modifications like stomata and trichomes. This
research was conducted with the aim of identifying one of the epidermal
derivatives in plants from the Asteridae subclass. In this study, the method used
to observe epidermal cells was the Halsil descriptive method obtained based on
research the form of the epidermis on some leaves of the Asteridae subclass,
including the frangipani plant (Plumeria) which has stomata of the parasitic
type. Furthermore, eggplant (Solanum melongena) has non-glandular type
trichomes. After that, the cayenne pepper (Capsicum sp) had anisocytic type of
stomata. Then the tomato plant (Lypersicum esculentum) has anomocytic type
of stomata. In addition to the derived form of the epidermis on the leaves, there
are stomata, trichomes, bulforms, lithocyte cells and myrosin. Furthermore, in
the stem there are silica cells and cork cells. Then at the root there are root
hairs and velamen. Derivatives of the epidermis, Stomata, Trichomes.

Birds have ecological, economic, and socio-cultural roles. Birdwatching is use of birds for tourism by seeing or hearing bird directly in nature. The GGPNP has potential for developed as a birdwatching destination. The research aims to identify the bird diversity and their distribution for the development of birdwatching at the Situgunung Resort and the Cimungkad Resort, GGPNP. The research was conducted in April-June 2022 in seven tracks using the IPA method. Qualitative data analysis was carried out on the bird status, while quantitative data analysis was carried out for diversity index, evenness index, and encounter opportunities. The bird diversity found was 50 species from 23 families and seven orders spread over seven observation tracks. Thirteen bird species are protected, three species are the CITES Appendix II, and two species are the IUCN Red List. The most common bird species were found on the Orchid Tourism Track while the least were found on the Cimungkad Tourism Track. Natural forest habitats support a wider variety of birds than any other habitat. The diversity index and evenness index are the high category. Most of the bird species fall into the category of very hard to find. All tracks have the potential to be developed as birdwatching routes.

The problem of this research is the implementation of learning that is still conventional, minimal variations in learning models, causing students to become bored and low learning outcomes. One of the problem solving is done through the use of the scramble learning model assisted by poster media. The aim of this study was to determine the effect of the poster-assisted scramble learning model on student learning outcomes at Andaluri Waingapu Catholic Middle School. This type of research is a quasi-experimental research design using nonequivalent control group design, with a quantitative approach. The research sample was 28 VIIIa students as the control class and 28 VIIIc students as the experimental class. Data collection techniques pretest, posttest, interviews. The results showed that the average value of the experimental class was 78.93, which was greater than that of the control class, 63.21. The results of the paired sample t test posttest data for the experimental class obtained a sig (2-tailed) value of 0.000 <0.05, concluding that the scramble learning model assisted by poster media had an effect on student learning outcomes in class VIII on the material Structure and Function of Plants at Andaluri Catholic Middle School Waingapu.

The phenotype of a living thing is determined by the DNA sequence inherited from the male and female parents. The phenotype of a cross on sweet potato (Ipomoea batatas) cannot be predicted using Mendel's Law rules because the dominance/recessive trait in the parents is not known, as a result of self sterility. This study aims to describe the morphological structure of tubers and leaves resulting from natural crosses of Asesi Antin 1 and Beta 2 sweet potatoes. The study was conducted in an observational non-experimental manner on plants resulting from natural crosses of sweet potato Antin 1 with Beta 2 assesion. All seeds resulting from the crosses were germinated in soil : sand media with a ratio of 3: 1. Furthermore, the growing sprouts were planted in plastic pots with a diameter of 30 cm with a medium consisting of soil: sand: compost = 3: 2: 1,then harvested after 7 months of age. The tuber morphological structures observed were shape tuber character, skin color predominant, and tuber flesh predominant color characters, while the leaf morphological structures observed were circumscriptio, margo folii, number of lobus, and the leaf vein color. The number of seedlings that managed to grow to maturity was 10 plants and had a variety of tuber and leaf morphological structures

One plant did tubers, and the other 9 plants produced of tubers.The morphological characteristics of the tubers and leaves of all individuals were as follows: 1) tuber shape characters, rounded, oblong and obovate for 1 plant each, long irregular, long oblong and ovate for 2 plants each; 2) the dominant color of tuber skin, 1 plant was purple, 5 plants were cream, and 3 plants were red; 3) the dominant color characters of tuber flesh were purple and white-purple each 3 plants, 2 plants were yellow-white and 1 plant was yellow; 4) the character of circumscriptio of triangular leaves is 3 plants and the cordatus leaves is 7 plants; 5) the character of the margo folii, 3 plants are palmati fidus, 5 plants are palmati partitus and 1 plant is palmati lobus; 6) the character of the number of lobes, 3 lobes is 3 plants, 5 lobes is 5 plants, 4 and 7 lobes is 1 plant each; and 7) the character of the vein of leave, green veins is 8 plants, purple and purple at the base only is 1 plant each.

The use of multimedia microbiology teaching materials integrated with STEM to empower students' critical thinking and communication skills has not been carried out optimally. The aim of the study was to determine the effect of STEM (M-STEM) integrated multimedia microbiology teaching materials on students' critical thinking and communication skills. The study method is quasi-experimental through a non-equivalent control group design pretest-posttest research design. The independent variable of the study is M-STEM microbiology teaching materials, and the dependent variable of the study is students' critical thinking and communication skills. The research sample was students from the Biology Education Study Program at IKIP Budi Utomo who were taking a Microbiology course. Class A is the research experimental class and class B is the control class. The research instrument was a multiple-choice type test for pretest and posttest questions. The research data are pre-test and post-test scores from the experimental class and control class which will be tested for prerequisites (normality and homogeneity) first and then will be tested with the ANAKOVA test with SPSS. The results of this study indicate that there is an effect of STEM (M-STEM) integrated multimedia microbiology teaching materials on students' critical thinking skills (sig<0.05) and student communication (sig<0.05). The research concludes that multimedia-integrated STEM (M-STEM) microbiology teaching materials have a positive effect on students' critical thinking skills and communication.
