21st century learning has had a huge impact on students and teachers. Students must be guided to be able to think critically to overcome various kinds of problems that occur. Furthermore, teachers as education play an important role in honing problem solving skills in their students. The problem solving learning model is a learning model that directs students to solve problems in the learning process. In addition, the problem solving learning model is not fully capable of being applied by science teachers. Although, in the 2013 curriculum in Indonesia a teacher is required to be able to apply the problem solving model in conducting science learning. Not only that, the limited experience of teachers in applying variations of these learning models is still the main obstacle in learning science. So, teachers in Indonesia must have extensive experience in adopting problem solving learning models. This study aims to determine the effectiveness of the problem solving learning model in learning science in Indonesia. This research is a kind of meta-analysis research. The research sample came from analyzing national and international journals published from 2010-2022. The selection of data used as samples was carried out very strictly and thoroughly. Searching for this research sample through Google Scholar, Eric, Hindawi, Sage, Springer, Proquest, IEEE, DOAJ, and Wiley. The sample selection technique is a purposive sampling technique. In this technique, the data that is used as a sample must have a relationship with the research variable. In searching for sample keywords, namely problem solving learning models in learning science (Biology, Chemistry and Physics) in various schools in Indonesia. Data analysis is descriptive statistical analysis with the OpenMEE application. Data analysis was performed by calculating effect size, standard deviation (SD), average value (mean), and N-gain. The results of this study concluded that the application of the problem solving learning model was very effective in learning science in Indonesia. This learning model is able to increase student learning outcomes with an average score of 86 students in the experimental class and 65.5 in the control class, the effect size value is 1.39 in the high category and N-Gain is 0.55.

This study discusses the meaning contained in the logo of the Province of Gorontalo in semiotic analysis. Logo is the identity of an institution that represents the history and culture of the institution while semiotics is the science of reading signs both verbally and visually, visual forms make the vision and mission as well as identity reflected in a logo. Just like the regional logo of Gorontalo Province which has various meanings of signs and symbols that reflect the area, for example, the Padi and cotton symbols are inspired by the city government logo which means depicting prosperity and others. There is also an oval pattern in the logo taken from the eggs of the Maleo bird, which is endemic to Gorontalo. There is the fort of Otana and pictures of books taken from our philosophy "adat based on sara', sara' based on the book of Allah. The purpose of the study was to describe and analyze what the meaning of the symbols in the logo of the Gorontalo Province were. The research used semiotic analysis of Charles Sanders Peirce. Semiotics departed from three main elements, which Peirce called the triangle theory of meaning, namely: signs, objects, and interpretants. The meaning of the logo can be studied scientifically with semiotic theory. In Peirce's study, symbols are divided into 3 categories: icons, indexes, and symbols. To analyze the meaning of symbols, Peirce uses 3 semiotic terms: representamen which is a symbol, semiotic object which is a real object of symbol reference, and interpretant which states the relationship between representamen and semiotic objects. Benefits of this research To add scientific insight in the field of linguistics, especially to the use of semiotic theory and to find out creative strategies in promotional activities of a government institution so that they can build a brand in the eyes of the public. The results of this study determine the meaning of the signs on the regional symbols of Gorontalo province. The output of this research is a scientific paper published in an accredited national journal.This study discusses the meaning contained in the logo of the Province of Gorontalo in semiotic analysis.

Science and technology will facilitate human work. However, on the other hand it will increase competition. In facing intense competition, it is necessary to have competent human resources. Students are expected to be academically prepared, in the form of knowledge and skill readiness to face increasingly fierce competition. One way to see student competence is to look at learning outcomes that can be represented by the exam scores taken. The midterm exam (UTS) is a form of exam which is an assessment component. By knowing the UTS scores, the lecturer knows the distribution of students in terms of academic competence. For this reason, it is necessary to group (clustering) using the k-means algorithm as a consideration for lecturers in forming student study groups based on UTS value clusters.
