Abstract

One of the sea potentials in Aceh is seaweed. Seaweed contains secondary metabolites and antioxidants that are very well consumed because it can act as an antidote/protector from the free radicals. This study aimed to determine the secondary metabolite content and antioxidant activity of seaweed in Aceh.The seaweed that has been macerated then screened for phytochemicals and tested for antioxidant activity by using the DPPH method. The seaweed species found were Gracillaria verrucosa, Sargassum sp., and Chaetomorpha antennina. The results of this study indicated that Gracillaria verrucosa, Sargassum sp., and Chaetomorpha antennina seaweeds were contained by alkaloids and steroids. Flavonoid and saponins were only detected in the types of seaweed Gracillaria verrucosa and Sargassum sp. It was also found that the higher the concentration of the extract, the higher the percentage of IC50 against free radicals. The Sargassum sp. has a stable percentage of inhibition at a 2-10 ppm concentration, so it is recommended in this study to be considered cultivated in Aceh.

Abstract

Online learning requires students to be more independent in learning. For example, chemistry learning tends to contain abstract concepts (very theoretical), so it requires a more detailed description and explanation. To help solve this problem, we need a media that can make it easier for students to learn during online learning. The purpose of this study was to determine student perceptions or responses to learning using teaching videos. The method used in this research is descriptive quantitative, which will produce a description of quantitative data related to student perceptions of the results of the Cronbach Alfa test. The instruments in this study were questionnaires, and learning outcomes test questions. The sample consisted of 102 students. Before being used, video-based learning media with the help of a pen tablet were validated by media and material experts, both in terms of construction and concepts contained in the learning media. The validation results obtained an average value of 0.91 which means it is very valid. Further analysis using reliability showed the Cronbach Alfa coefficients were 0.88, respectively; 0.92; 0.93 consecutively for aspects of knowledge, media and convenience. In order to be accepted by the media as learning media, it is necessary to look at student responses to aspects of knowledge (P) where the average value is 3.96 which is classified as good, media (M) 4.02 and convenience (K) 3.81 are also included in good category.

Abstract

Molasses fermentation from molasses has been studied as an alternative to renewable energy. The goal of this research was to determine molasses fermentation as an alternative to renewable energy. The goal of this research was to monitor the alcohol concentration and pH levels during the fermentation process. This study employed a completely randomized design (CRD) method with two components. Factor A is the amount of time required for aeration. Molasses dilution is factor B. Factor A was tested across four different time periods: 24, 48, 72, and 96 hours. Factor B was tested using three different ratios: 1: 1.5, 1: 2, and 1: 2.5. The calculations of alcohol content FcalcP = 74.35> Ftable (11; 36; 0.05) = 2.07 and Ftable (11; 36; 0.01) = 2.79 revealed that components A and B had a significant impact on the final alcohol content. The BNJ 1% was calculated to be 0.63. This demonstrates that A4B3 is the most effective treatment. FcalcP = 2.85> Ftable (11; 36; 0.05) = 2.07 and Ftable (11; 36; 0.01) = 2.79, indicating that factors A and B have a highly substantial effect on acidity (pH). The BNJ 5% was obtained at a value of 0.61. This also demonstrates the optimal acidity conditions in A4B3 therapy. Based on these findings, it is clear that aeration for 96 hours and dilution with a 1: 2.5 ratio produce the greatest outcomes and the maximum alcohol content. At a pH of 4.45, the average bioethanol content is 6.31%.

Abstract

The development of virtual laboratory(VL) has been widely used in secondary school teaching, notably science education. However, the development of VLspecifically for university-level education remains quite limited. In addition, in some practical disciplines, such as membrane-based separation chemistry, both lecturers and students face restrictions in equipment and resources. As a result, the goal of this study is to develop a VL for membrane synthesis practicum utilizing the phase inversion approach that can also be utilized in separation chemical practicum. In addition, the researchers assessed the amount of legitimacy and user response to VL media, specifically among students. This work follows research and development based on ADDIE (Analysis, Design, Development, Implementation, and Evaluation) framework. The first phase is begun with an analysis (via interviews) to investigate the lecturers issues and needs. Consequently, the analysis confirmed that the development of VL in separation chemistry is very essential. The researchers used feedback from the lecturer during the design stage, namely while gathering the material and presentation of VL to create the storyboard. Then, three experts confirmed the draft created during the development stage, declaring it highly validwith a proportion more than 85%. Face validity and construct validity took major revision to achieve 100% of highly valid. Following the revision steps of draft I (initial version) based on the validation results, draft II (revised version) was created for restricted testing with users (students), and the results revealed a very good response, with more than 90% of students providing feedback ranging from agree to highly agree. Their responses represent the impact received from VL, particularly in digital literacy, building critical and creative thinking, and learning flexibility. Some suggestions for enhancement, particularly the usage of foreign languages in VL, will be considered in the final stage. Thus, the VL can be recommended for use in membrane synthesis experiments in the separation chemistry course.
