Abstract

The current state of the Covid-19 pandemic has had an impact on various ongoing activities, including learning activities. Currently, the government provides a policy to organize learning from home, known as Learning From Home (BDR). Learning From Home in its implementation requires the support of mobile devices. It is a challenge for both teachers and students to master technology in learning in these conditions. In addition, teachers must also be able to carry out the teaching and learning process or provide assessments/evaluations to students face-to-face (done online). The research objective is to determine the use of alternative assessment-based portfolios in biology learning. The authors want to introduce web-based portfolios as alternative assessments in biology learning in this study. Alternative assessments can support students to understand biology lessons with the task of making lab reports, making herbariums, drawing, writing widespread scientific reports, etc. These are collected in the form of website links. The research method used is a literature study that the author has carried out. The results obtained are using a web-based portfolio as an alternative assessment in biology learning, which is still not widely applied even though this assessment is very efficient to apply in biology learning during the Covid-19 pandemic. This research concludes that every lesson that has been carried out certainly needs to be assessed on student learning outcomes in following each lesson that has been followed. In this case, an alternative web-based portfolio assessment is one of the solutions to evaluate the performance and work of students so that all activities carried out can be rewarded with value.                 Keywords: Biology Alternative Assessment, Web Based Portofolio

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
