Critical thinking skills are an important competency in learning biology, especially in biodiversity materials that require analysis, reasoning, and decision-making. This study aims to determine the influence of the Guided Discovery Learning learning model on the critical thinking ability of grade X students at SMA Negeri 2 Tondano. The method used was a quasi-experimental study with a pretest-posttest control group design. The sample consisted of two classes, namely the control class that was taught using the conventional model and the experimental class that received treatment with the Guided Discovery Learning model. Data were collected through pretest and posttest written tests, and analyzed using normality, homogeneity, and t-test. The results showed that there was a significant difference between the learning outcomes of students in the experimental class and the control class. The average posttest score of the experimental class was 81 higher than the control class of 63.5. In addition, the Tcal value of 4.65 is greater than the Ttable of 2.02 at a significance level of 0.05, which shows that the Guided Discovery Learning model has a positive influence on improving students' critical thinking skills. This result is also strengthened by a decrease in standard deviation which shows an equal distribution of understanding between students. This research contributes to the development of active learning strategies in biology education and suggests the application of this model to improve higher-level thinking skills. This model is also relevant applied to other topics in order to strengthen discovery-based learning and collaboration.

Low motivation to learn and limited conceptual understanding are significant challenges in learning biology at the junior high school level, especially in abstract material on the classification of living things. This study aims to analyze the influence of the use of animated videos on student learning motivation and learning outcomes. A quantitative approach with a pre-experimental design of one group pre-test and post-test was used in this study. The research sample consisted of 25 students in grade VIII of SMP Negeri 2 East Likupang. Data was collected through observation sheets to assess learning motivation and pre-test and post-test tests to evaluate learning outcomes. The results of the observation showed that the average motivation of students reached 86.32% in the outstanding category. The average pre-test score of 59.57 increased to 81.09 on the post-test, indicating a significant improvement in concept comprehension. The t-test corroborates these findings with a significant value at a 95% confidence level. These results show that animated videos can present a visualization of complex concepts in an engaging and contextual way, thereby increasing students' focus, active participation, and absorption of the material. In addition, the use of this media also supports the development of students' collaborative skills and critical thinking. This research confirms that animated videos are a strategic alternative in effective science learning, especially in school environments with limitations of conventional visual media. It is suggested that the application of this media be expanded to various materials and levels of education.

This study aims to evaluate the effectiveness of the JAS (Exploration of the Surrounding Environment) approach and the STAD (Student Teams Achievement Division) type of Cooperative Learning Model in improving students' learning outcomes in biology subjects. The results of the study indicate that in Cycle I, out of a total of 15 students, 10 students had not yet met the Minimum Mastery Criteria (MMC), with a percentage of 66.67%. In Cycle II, only 2 out of 15 students had not reached the MMC, representing 13.34%, while the remaining 13 students achieved the MMC, accounting for 86.66%. These findings demonstrate an improvement in student learning outcomes following the implementation of the applied learning models. The conclusion of this study contributes to the development of more effective instructional methods to enhance student achievement and provides insights for educators in designing instruction that aligns with students' needs and interests.

Rifani Chatrin Liwutang. 18 502 003. Effectiveness of PGPB (Plant Growth Promoting Bacteria) from the roots of the Putri Malu (Mimosa pudica) plant on the chlorophyll content and stomata of cayenne pepper (Capsicum frutescens). Thesis. Biology Study Program, Faculty of Mathematics, Natural and Earth Sciences, Manado State University in Tondano. 2024. Dr. Aser Yalindua, MP as supervisor I and Danny Christian Posumah, S.Si, M.Si as supervisor II. Cayenne pepper (Capsicum frutescens) is one of the vegetable commodities that people really need as an ingredient to add flavor to food. Problems often faced by chili farmers include the availability of fertilizer and the presence of pest plants for cultivated plants which affect plant productivity. The aim of this research is to determine the effect of giving PGPB (Plant Growth Promoting Bacteria) from the roots of the putrimalu plant on the chlorophyll content and stomata of cayenne pepper leaves. This research was carried out at the Biology Department Laboratory, FMIPAK, Manado State University. This research used a Completely Randomized Design with five PGPB treatments, namely; P0= Control, P1= 10 ml, P2= 20 ml, P3=30 ml and P4=40 ml in three replications. The data was analyzed using Oneway Anova and continued with the Post Hoc LSD (Least Significant Difference) test at a confidence level of 95%. The results of this research show that PGPB treatment can increase plant growth such as plant height, number of leaves and root volume.

Paddy rice is the main food crop in Indonesia because rice is the primary food source of the Indonesian people. However, it faces obstacles caused, among others, by the presence of nuisance plants, namely weeds, that can reduce the quantity and quality of harvest or production. This study examines the value of the dominant Number of weed populations in rice field cultivation. The research method used was weed observation with analysis of the chief number value, using the square of a sample plot measuring 50 cm x 50 cm, randomly placed on the experimental land. The dominant number value analysis was carried out four times at the beginning of the study as an initial vegetation analysis, 21 DAP observations, 45 DAP observations, and 60 DAP observations. The results showed that the weed species with the highest Dominant Number Value at initial words in paddy fields were Paspalum disticum, Fibristylis litoralis, Marsilea crenata, Cyperus iria, and Ludwigia octovalvis; weed species with the highest Dominant Number Value at 21 DAP observations were P. disticum, Echinochloa crusgalli, F. litoralis, M. crenata, and Leersia hexandra; The weed species with the highest Dominant Number Value at 45 DAP observations were P. disticum, F. litoralis, C. iria, E. crusgalli, and Leersia hexandra and the weed species with the highest Dominant Number Values at 60 DAP observations were E. crusgalli, P. disticum, F. litoralis, Scirpus juncoides, and S. juncoides

The Yaki monkey (Macaca nigra) is a critically endangered endemic species of North Sulawesi and is listed in Appendix II of CITES as well as in-situ conservation at the Tangkoko Conservation Forest Management Union (KPHK Tangkoko). The public's knowledge of the conservation of M. nigra is a key factor inining the sustainability of this species. The aim of this research is to find out the level of public awareness about conservation of M. nigra. This research uses descriptive methods. Data collection is done with a questionnaire with scored using the Guttman scale. The results of this study show that the majority of the level of knowledge in the community in the buffer zone KPHK Tangkoko belongs to a level of good, sufficient, and insufficient to the conservation status of m. nigra. Respondents who have good knowledge are all respondents in the Batu Putih Bawah villages and Duasudara villages. While the majority of the population in the Kasawari villages (63%) and the Pinangunian villages (68%) have sufficient knowledge about the conservation status of the M. nigra while almost half of the Kasawari villages (37%) and Pinangunian villages (32%) have insufficient knowledge.
