Abstract

One of Rawa Besar Small Lake’s roles for the surrounding community is as a fishing spot. Locals would often go fishing at the edges of the small lake. The ability of a lake to provide fishes to catch is partly due to the availability of food in the ecosystem, most importantly the microalgae community as the main producer in the freshwater food web. This concept is used in aquaculture as a way to obtain a more sustainable ingredient for feedant. Microalgae are used for aquaculture feedant due to its nutritional value. However, it is important to assess the safety and suitability of microalgae used for feedant due to the difference in toxicity and nutritional value of various microalgae species. Observation of the water samples taken from Rawa Besar Small Lake shown that potential microalgae species like Kirchneriella and Arthrospira lives in Rawa Besar Small Lake. However, toxic microalgae species like Planktothrix has been found in said water sample as well. Isolation of potential species is necessary in order to produce a healthy feedant for aquaculture out of Rawa Besar Small Lake’s microalgae community

The instrument was developed by the researcher to assess students’ computational thinking in Grade Eleventh in high school on heat and transfer topics under STEM Quartet Integrated Learning. The type of the instrument is a multiple choice with multiple-choice reasoning. This test consists of 13 questions to measure five concepts of Computational Thinking which are abstraction, decomposition, algorithm, evaluation, and generalization. The test was tried out on 120 students (87 female and 33 male aged 16-18 years old) in West Java and Banten. The item of the questions on the test was analyzed using Winstep 5.3.2.0. The reliability of the Instrument can be shown at the Cronbach’s alpha, Item Reliability, Person Reliability, Item Separation, and Person Separation. The result shows that Cronbach’s alpha (KR-20) is 0.75 which means the instrument has high reliability. The value of the item reliability is 0.95 and person reliability is 0.72. This means that although the consistency of student in answering questions is sufficient, the instrument has high reliability. The values of the item and person separation are 1.61 and 4.43 which means that the instrument has great separation. The validity of the instrument can be seen in unidimensionality and item fit order. The unidimensionality shows that the value of Raw Variance Explain by Measure is 32.8%, the Unexplained variance 1-5 contrast is below 15% and the eigenvalues are also below 3%. Overall, 8 of 13 items of the test meet 3 criteria of the item fit order, then 5 items have 2 of 3 criteria of the item fit order. We can conclude that this Instrument is reliable and valid. Then, the instrument can be used to measure students’ computational thinking on heat and transfer topics

Abstract

The COVID-19 outbreak had transformed the chemistry learning from physical class to online class. The alteration in class method could be challenging for several instructors, particularly those who were not aided with technological advancements and adequate training. One of the challenges was the selection of software and tools used in online lectures as well as online experiments class. Herein, we present a systematic literature review with the PRISMA model from two databases regarding the software and tools many researchers used in chemistry learning during COVID-19 pandemic. The particular steps of laboratory activities and students’ perspectives towards these learning tools were also incorporated in the results and discussion. At the end of the review, we provide the promising directions of learning tools for future chemistry learning too
