Wasted sweet potato peel waste is a classic problem in Indonesia, therefore the use of sweet potato peel as biomass for bio-battery production can be used as a solution to this problem. This study aimed to determine the benefits of sweet potato peels and orange solution as biomass for bio-battery production. The main novelties in this study are (1) Used sweet potato peels as bio-battery Material that have never been used in previous studies. (2) Used sweet potato peel as fixed variable and lime juice as independent variable, and (3) Tested the sweet potato peel and lime juice pasta into the clock. This method is done by smoothing the skin of the sweet potato with the addition of 40 mL of lime solution to form a paste. The lime solution used in this study was 0; 5; 10; 15%. Then measure the voltage of the bio-battery and test the wall clock with the bio-battery. The experimental results showed that the sweet potato peel paste with a lime solution produced the same voltage as an ordinary battery at a concentration of 10% with a value of 1.47 V. The bio-battery with the highest concentration variation is not necessarily the best, that's because the pH value affects the current and voltage. The conclusion of this research is that sweet potato peel and lime solution can be used as electrolytes in bio-battery production with optimal variation of 5 and 10%. This study demonstrates the utilization of sweet potato peel waste as an alternative biomass for bio-battery production.

The ability of students to learn mathematics, especially in solving mathematical problems, is quite low. The pandemic conditions forced distance learning so that it hampered the improvement of students' ability to solve mathematical problems and non-mathematical problems. Innovation in learning is needed to help students to always be motivated in learning mathematics. This study aims to determine how much benefit the YouTube platform is as a distance learning medium to improve students' ability to solve problems mathematically. This activity method uses a quantitative approach with the target of grade 5 elementary school students. The results showed that the post-test average of students was 83.4%, an increase of 25.9% from the pre-test results which only reached 57.5%. This shows that videos uploaded to the YouTube platform can be an effective and innovative way to improve the mathematical problem-solving abilities of elementary school students.

Literacy is a language skill possessed by someone in communicating. Literacy habituation needs to be done from an early age because it will make children accustomed to literacy which will also be able to cultivate their imagination. At this time, many parties apply literacy to early childhood with an inappropriate process, some children are required to be able to read and write in a method that requires children to think hard. By using picture storybook media, it will foster children's literacy skills. In this quantitative method, the authors take samples from several children with observational data collection techniques, namely interviews and questionnaires. The results of data collection stated that eight out of ten children succeeded in following the literacy habits that the authors applied. Therefore, literacy is very important to be applied to early childhood so that children can have the ability to communicate effectively that can develop their potential and participate in community life in the future.

The COVID-19 pandemic has had a major impact on education in Indonesia. Various efforts were made to attract students' interest in learning, one of the efforts made by the teacher was a learning video with the aim that students were able to understand the lesson well. The purpose of this study was to determine the effectiveness of the Youtube application as a means of learning sports for junior high school students during the pandemic. The results of this activity data show 52% of the students' basic volleyball knowledge pretest results were obtained. However, after giving the material with Youtube videos, the post-test results of knowledge increased to 84% so that learning through Youtube videos can improve student literacy. Therefore, there is a need for variations in learning methods during this pandemic which are expected to be able to improve the literacy quality of students.
