Abstract

Education is an effort to change behavior which includes three aspects, namely, cognitive aspects, psychomotor aspects and affective aspects. The assessment instrument used can be an assessment rubric containing performance achievement categories.  In simple terms, a rubric is defined as an assessment reference that shows a number of criteria for displaying the process or results of students' work. The use of rubrics in assessment will provide a real picture of student abilities. This research is a qualitative descriptive type of research which aims to determine teachers' difficulties in preparing assessment rubrics. This research was carried out at SMP Negeri 3 Kolaka using the interview method with biology teachers at the school. Research results show that teachers do not experience difficulty in preparing assessment rubrics. Assessment rubrics really help teachers find out student learning outcomes. Keywords: Teacher Difficulty, Rubric, Biology Learning

Abstract

This research aims to determine the effect of giving POC to tofu waste production of cayenne pepper plants, as well as knowing the effective POC dose for cayenne pepper plants. This research was carried out from November 2022 to January 2023 and took place in Sea Village, Kolaka Regency. This type of research includes experimental research consisting of 5 treatments and 4 replications to obtain 20 polybags with a total of 20 research plants. The parameters observed were the number of fruits (fruit) and fruit weight (grams). The research results show that from the parametric test using analysis of variance (ANOVA), the parameter data value for the number of fruit is 0.082 and the weight of the fruit is 0.225; the significance value is more than 0.05, thus H0 is accepted and H1 is rejected. So it can be concluded that there is no significant effect of giving tofu waste POC on the production of cayenne pepper plants. Keywords: Cayenne Pepper Plants ( Capsicum frutescens L.), Tofu Waste POC, and Production

Abstract

Teaching aids are considered an important tool because they are used by educators in the delivery of education. The problem of facilities and infrastructure is considered an important issue in education, therefore it is necessary to update the existing facilities and infrastructure starting from updating school buildings to learning facilities. This research to determine the effectiveness of using teaching aids on the interest and learning outcomes of science in class VII students at Junior high school 9 Kendari. The type of research used is Quasi-Experimental Design research in the form of Non-Equivalent Control Class Design. Data collection methods are carried out through questionnaires and tests The population of this study was all seventh grade students of Junior high school 9 Kendari which amounted to 11 study class, with the research sample being class VII 10 which amounted to 27 students as the control class and class VII 8 which amounted to 30 students as the experimental class. Data analysis techniques used are descriptive and inferential data analysis techniques. From the research conducted related to the effectiveness of the use of diorama teaching aids obtained research results that in learning, there are differences in interest and learning outcomes between the control class that does not use teaching aids with experimental classes that use teaching aids. In addition, based on the N-gain test, the use of diorama teaching aids proved to be effective with the category of medium effectiveness level. Keywords: Effectiveness, Teaching Aids, Interest in Learning, Learning Outcomes, N-Gain

Abstract

The photosynthetic activity of chili (Capsicum annuum L.) leaves greatly influences sunlight radiation, the role of photosynthesis produces food that can help in plant growth and development. If a plant lacks light, it will not produce chlorophyll so it will be pale in color. Abnormalities in the photosynthesis process will also affect the formation of carbohydrate compounds in the leaves. The carbohydrate content of chili leaves plays an important role in the metabolism of chili plants. This research aims to determine the effect of solar radiation on the photosynthetic activity of chili leaves using the Sach test . This research method uses descriptive methods.  Sampling was carried out by purposive sampling and giving the chili leaves a closing and opening treatment using aluminum foil under direct sunlight. The data analysis technique used is a qualitative descriptive analysis model, where this model is included in the type of qualitative research which is described descriptively. The results of the research showed that the parts of the leaves that were exposed to sunlight produced more chlorophyll, the leaf color was darker green, and produced starch which was characterized by a blue-black or dark purple reaction when given an iodine solution. Meanwhile, the parts of the leaves that are not exposed to sunlight show less yield, the color of the leaves is paler or yellowish.Keywords:  Sollar Irradiation, Capsicum annuum, Chili Leaf, Photosynthesis

Abstract

Photosynthesis is the process of preparing organic substances H2O and CO2 into complex organic compounds that require light. Photosynthesis can only occur in plants that have chlorophyll, a pigment that functions as a catcher of sunlight energy which will later be converted into amylum. Amylum as a complex carbohydrate resulting from photosynthesis, plays an important role in various important physiological processes in the leaves. The purpose of this study was to determine the amylum content in tomato (Solanum lycopersicum) leaves. Qualitative descriptive method was carried out by referring to Sach's method by measuring the starch content of leaves using foil and betadine (Iodine) on tomato leaf samples. The results showed the presence of amylum in tomato leaves that were not covered with aluminum foil after being tested with Iodine solution. This is evidenced by the change in leaf color to blue-black on the surface of the leaves. While in tomato leaves covered with aluminum foil the color of the leaves turns pale and there are only a few blue-black spots, this indicates that leaves that are not exposed to direct sunlight and do not undergo photosynthesis normally have little amylum content in them. Keywords: Amylum, Solanum lycopersicum, Sach Test

Abstract

The tomato plant (Solanum lycopersicum) is native to the Americas, from the area around Mexico to Peru. Tomato stems, although not as hard as perennial plants, are quite strong. The color of the stem is green and is rectangular to round. The research method as well as analyzing the structure of tomato stems using descriptive methods. The research is descriptive analysis. Sampling was carried out at 16.00 WIB and only used one sample of tomato plant species and then made observations using a microscope with the help of section preparations. The data analysis technique used is a qualitative descriptive analysis model, where the model is included in the type of qualitative research described descriptively. The results showed that young tomato (Solanum lycopersicum) stems observed through a microscope with a magnification of 10x can be seen that only the epidermis, the cortex area (without being able to distinguish the tissue contained in the area), the transport tissue (without being able to know the location of xylem, phloem and other tissues) and the pith area where in this area the perenkim tissue is clearly visible.  Keywords:  Stem Anatomy, Solanum lycopersicum, Plant Tissue
