<![CDATA[The use of plastic is still favored by most people today, which has increased the amount of plastic waste. One of the bacteria that can carry out plastic bioremediation is found in mangrove ecosystems. The existence of the mangrove ecosystem is found on Sine Tulungagung Beach, but there has never been further exploration regarding the presence of plastic-degrading bacteria. This research was conducted to explore the presence of potential plastic-degrading bacteria in the mangrove area of the Sine Tulungagung coast. This study used a descriptive-qualitative method that began with planting plastic samples in mangrove deposits, followed by taking bacterial samples from the mangrove area of Sine Beach, Tulungagung. 21 bacteria were isolated from the exploration and tested for their ability to reduce the weight of the plastic. Bacteria with the ability to decompose plastic were then identified using morphological (color, shape, edges, elevation, and size) and biochemical (gram staining and catalase enzyme) tests. It was found that the highest plastic weight reduction was 6.97%, with the most characteristics in the form of coccus and gram-negative bacteria.]]>

<![CDATA[Colony counter tools are used to count bacterial colonies. The high price constraint makes manual calculation the preferred alternative. In this study, Innovations were made to the SI PINTER tool by replacing the power source with a battery and using digital prayer beads connected to a marker to display the results on the screen. The purpose of this study was to develop the SI PINTER tool as a microbiology laboratory support to improve the accuracy of bacterial colony counts. Standardization of the SI PINTER tool is done by comparing the results of calculations using a conventional Colony Counter and without using equipment (manual) to get accurate results of the number of bacterial colonies. This research method is quasi-experimental and the data was analyzed by One Way ANOVA test. The results of the One Way ANOVA statistical test showed a p-value = 0.996 > 0.05, indicating that there was no significant difference between the results of the number of bacterial colonies using conventional Colony Counter, SI PINTER and manual calculations. The SI PINTER tool can be used according to its function as a microbial colony counter and has portable capabilities because it only relies on electrical energy from batteries]]>

<![CDATA[This study utilized a quasi-experimental research design in the form of a pretest-posttest control group. It aimed to examine the impact of textbooks assisted by quartet cards on science literacy skills and student learning motivation. The research sampling was conducted through a simple random technique, selecting XI MIPA 5 class as the treatment group and XI MIPA 3 as the control group. Data was collected using multiple-choice tests to measure science literacy skills and questionnaires to assess student learning motivation. The descriptive and inferential analyses were conducted, employing non-parametric tests (Mann-Whitney) as the data analysis technique in this study. The results of the descriptive analysis illustrated that students taught with textbooks assisted by quartet cards exhibited science literacy skills in the medium category, while their learning motivation was rated as very high. Based on the results of the inferential analysis, a significant difference was observed in the science literacy skills and learning motivation between students using textbooks assisted by quartet cards in the treatment class and those in the control class. The mean rank number in the treatment class consistently exceeded that of the control class in Biology at SMA Negeri 1 Wonomulyo. One limitation of the research is the shortage of quartet cards available for the learning process, which resulted in students taking turns rather than playing simultaneously. To address this, the teacher should prepare additional sets of cards, each accommodating four students, and effectively allocate time during the process of playing cards and answering questions in the textbooks. This will ensure that the learning process runs efficiently and effectively.]]>
