The Indonesian government is currently implementing two types of curriculums, namely the 2013 curriculum and the ‘Merdeka belajar’ curriculum which has been implemented for 2 years. Both of these differently named curriculums run together at different academic grades throughout Indonesia. Although they have different names, both curriculums have similarities in the application of their learning process, which is inquiry-based learning. Teachers can apply inquiry-based learning based on the guidelines specified in the curriculum or implement other inquiry-based learning methods, one of which is Wenning's levels of inquiry. This study aims to develop and strengthens the understanding of basic concepts in biology based on the student experience. This study investigates the impact of discovery learning on the development and strengthening of understanding basic concepts in biology, based on the experiences of students. The research aimed to explore the effectiveness of a discovery learning approach in enhancing students' comprehension and retention of fundamental biological principles. This study emphasizes the value of discovery learning as a powerful pedagogical approach for facilitating students' comprehension and mastery of basic concepts in biology. After carrying out the learning process with discovery learning steps, students get reinforcement of the basic concepts of the food digestive system and make it easier for students to carry out the next stage of inquiry.

This study aims to determine the differences between male and female students’s problem solving abilities in environmental change topic based on ESD. This study used pre-experimental method with one group pretest – post test design. This study located at MA Darul Muqorrobin with subjects 30 students of class X who selected using a purposive sampling technique. Generally, female students’s problem solving ability is higher than male student’s, with a final value of 77.7 for male students and 82.3 for female students. Male students have an average total score higher than female students on the problem understanding indicator, namely 7.7 for male students and 7.4 for female students. In the problem-solving design indicator, female students have a higher average total score than male students, namely 6.1 for male students and 6.5 for female students. Female students have an average total score higher than male students on the indicator of carrying out problem solving, namely 5.8 for male students and 6.4 for female students. In the indicators evaluating problem solving, female students have an average total score higher than male students, namely 5.3 for male students and 5.9 for female students. The high female students’s problem solving ability due to the structure of woman’s corpus collasum which thicker than the men’s. Testosterone hormone causes men prefer learning that hands-on. The preoptic region in the men’s hypothalamus is larger than women’s so men can understand problem better than women. The interpretation of the N-Gain value is sufficient, so the learning of environmental change topic based on ESD is effective to improve problem solving ability in both students.

The Laboratory is a room or places equipped with tools and materials suitable for teaching science or implementing science practicum. Laboratory management in terms of organizational structure, activities, and facilities needs to be evaluated to increase awareness of the effectiveness of science learning and increase laboratory safety to the optimum level. This paper aims to determine 1) Standard Operating Procedures and 2) Obstacles in school SOP management. The research method used was descriptive exploratory. The data were collected by conducting interviews, observation, and documentation. The data analysis technique was carried out in descriptive qualitative. The results showed that the Biology Laboratory preparation at three Bantul Regency schools already had a Standard Operating Procedure (SOP). However, some schools have not fulfilled the SOP properly. Of the three schools observed in school C, there is no SOP for storing tools and practicum materials. School B SOP that has not been posted in the open, SOP for occupational health and safety, SOP for procurement of tools or practicum materials, and SOP for purchasing chemicals. School A does not have SOP posted in the open, SOP for storing tools or practicum materials, and procurement of tools or materials.

Paracetamol metabolism takes place in the liver mediated by CYP450 enzymes and generates NAPQI radicals. The NAPQI radical is highly electrophilic to hepatocyte biomolecules and is therefore capable of inducing liver damage. Laban tree bark (V. pubescens) methanol extract is known to contain antioxidant compounds of flavonoids, saponins, and tannins with an IC50 value of 19.83 g/ml. This study aims to determine the optimal dose of extract that can improve the liver microanatomy of mice induced by toxic dose of paracetamol (TDP). This study used 30 male Swiss strain mice with a body weight of 20-30 g. The treatments given consisted of negative control (paracetamol 105 mg kg-1), positive control (vitamin E 46.8 mg kg-1), and laban extract at a dose of 75; 150; 300; 600 mg kg-1 BW. Liver microanatomy parameters measured included hepatocyte diameter (19.50±0.21 µm), sinusoids (4.39±0.23 µm), and central vein (36.84 ± 1.79 µm). Data were analyzed using one-way ANOVA and Duncan's Multiple Range Test further test was then presented in the form of mean ± standard deviation. The results showed that extract at a dose of 600 mg kg-1 had hepatocyte, sinusoid, and central vein diameters that were not significantly different (p>0.05) with vitamin E.

Tree Species Diversity at Kebon Rojo, Blitar City. Kebon Rojo is one of the open green spaces in Blitar City. This area has a variety of vegetation, one of which is trees. Diversity of tree species in this area has not been recorded. This study aims to determine the diversity of tree species at Kebon Rojo. The method used is the Je method by recording and documenting the diversity of trees in this area. The level of diversity was calculated using the Shannon Wiener index. The results of this study revealed that there were 322 trees belonging to 26 families, 36 species. The Shannon Wiener Diversity Index is 3.5. This value indicates the diversity of tree species at Kebon Rojo is high

Achieving at least some level of explainability requires complex analyses for many machine learning systems, such as common black-box models. We recently proposed a new rule-based learning system, SupRB, to construct compact, interpretable and transparent models by utilizing separate optimizers for the model selection tasks concerning rule discovery and rule set composition.This allows users to specifically tailor their model structure to fulfil use-case specific explainability requirements. From an optimization perspective, this allows us to define clearer goals and we find that -- in contrast to many state of the art systems -- this allows us to keep rule fitnesses independent. In this paper we investigate this system's performance thoroughly on a set of regression problems and compare it against XCSF, a prominent rule-based learning system. We find the overall results of SupRB's evaluation comparable to XCSF's while allowing easier control of model structure and showing a substantially smaller sensitivity to random seeds and data splits. This increased control can aid in subsequently providing explanations for both training and final structure of the model.

We continue the study of Genetic Algorithms (GA) on combinatorial optimization problems where the candidate solutions need to satisfy a balancedness constraint. It has been observed that the reduction of the search space size granted by ad-hoc crossover and mutation operators does not usually translate to a substantial improvement of the GA performances. There is still no clear explanation of this phenomenon, although it is suspected that a balanced representation might yield a more irregular fitness landscape, where it could be more difficult for GA to converge to a global optimum. In this paper, we investigate this issue by adding a local search step to a GA with balanced operators, and use it to evolve highly nonlinear balanced Boolean functions. In particular, we organize our experiments around two research questions, namely if local search (1) improves the convergence speed of GA, and (2) decreases the population diversity. Surprisingly, while our results answer affirmatively the first question, they also show that adding local search actually increases the diversity among the individuals in the population. We link these findings to some recent results on fitness landscape analysis for problems on Boolean functions.
