<![CDATA[Education is a long term investment of human resources which has strategic values for the continuity of human civilization in the world. The teaching and learning process is a core of the overall learning process. The critical thingking skills is one of the main problems in learning because the domination of teachers who given less access for students to develop independently through their own findings and thingking process. The low learning outcomes also becomes a complex problem to date because the learning process is still center on the teacher; thus, students become passive. Teachers prefer to apply lecture method because it does not need tools and practice materials and only explain the concept continued in the textbook. The students are not being given the method which centered on the students. The study aims at examining (i) the critical thingking skills of students who have extrovert and introvert personalities at SMAN (public senior high schools) in Makassar city, (ii) the Biology learning outcomes of students who have extrovert and introvert personalities at SMAN in Makassar city, (iii) the difference of critical thingking skills between extrovert personality students and introvert personality students at SMAN in Makassar city, and (iv) the difference of biology learning outcomes between extrovert personality students and introvert personality students at SMAN in Makassar city. The study was ex-post facto. Data were collected by employing personality questionnaire, critical thingking skill test, and documentation of learning outcomes scores. The results of the study reveal that (i) the critical thingking skills of extrovert personality students are in well delevop category and the introvert personality students are in well develop category as well, (ii) the Biology learning outcomes of extrovert personality students are in high category and the introvert personality students are in high category as well, (iii) there is a difference of critical thingking skills between extrovert personality students and introvert personality students, and (iv) there is no difference of Biology learning outcomes between extrovert personality students and introvert personality students. Keywords: Critical Thingking Skills, Biology Learning Outcomes, Extrovert Personality and Introvert Personality]]>

<![CDATA[lotong is a sediment of dirty sap obtained from a sugar factory's sap purification process. The continuous accumulation of waste can cause environmental pollution. Blotong waste has the potential to be used as organic fertilizer using the vermicomposting method (composting with the help of earthworms). Blotong contains nitrogen, P2O5, humic acid, and other nutrients that can be used to fertilize and improve the structure of the soil. This study aims to determine the effect of the type of worm on the speed of decomposition of blotong waste and to determine the quality of vermicompost according to SNI 261-2019 regarding the specification of solid organic fertilizer. This study was structured using a one-factor completely randomized design (CRD) with three replications conducted in series. The series of observations were 2 MSP, 3 MSP, and 4 MSP (Week After Giving). The research factor was the type of worm consisting of Eisenia foetida (C1), Eudrilus eugeniae (C2), and Lumbricus sp. (C3). This research is destructive (not returned for further observations). The results showed that the compost with Eisenia foetida had a better content, namely C-organic (35.84%), pH (7.26), N-total (2.36%), and C/N ratio (15.19). The highest increase in worm mass was found in the type of worm Eisenia foetida, which had an increase of 7.11 g. Based on these results, sugarcane waste fertilizer meets the requirements of SNI No. 261/2019.]]>

<![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.]]>
