Abstract

The background to this research is the importance of finding an integration pattern between the project learning model and Ethno-STEM based inquiry to explain scientific knowledge regarding the aroma of herbal tea.  The fundamental research objective is to design an integration pattern for the project and Ethno-STEM learning model and reconstruct scientific knowledge based on public knowledge of the aromatic volatile compounds of Indonesian and world herbal teas. This research method and approach is mixed research. This qualitative approach is to find the integration of the project learning model and Ethno-STEM (Ethno-STEM PjLM) and its syntax. A quantitative approach regarding analyzing tea aroma volatile compounds using an Arduino gas sensor: research data from literature studies, interviews, reconstruction, and data on identifying volatile compounds in the aroma of herbal tea analyzed descriptively, qualitatively, and quantitatively. The results of the research concluded: (1) the reconstruction and integration pattern between PjLM Ethno-STEM is an integrated pattern with SUDARMIN syntax, (2) the reconstruction of scientific knowledge based on public knowledge regarding the process of isolation, extraction, and bioactivity of secondary metabolites, (3) herbal tea aroma volatiles compounds are identified by Arduino sensor: carbon dioxide, methane, propane, butane, acetone, alcohol, and ester, (4) the implementation of Ethno-STEM PjLM received a positive response from students.

The instruments used were questionnaires and interviews which were conducted a feasibility test before being used. The strategy employed was sequential explanatory by collecting and analyzing quantitative data followed by qualitative data. The articles of the participants were still unassigned and submitted from July to August 2020. The number of participants was 85 consisting of 78 lecturers, 4 students, and 3 teachers. The research results from questionnaire analysis were; the participants’ intention of visiting the JPII website as 53% to cite articles, the benefit that obtained was 69% getting references, the most interesting part of 62% was the results and discussion, the substance primacy of 35% was in the discussion section, and participants find it easiest to find novelties in the discussion section of 53%. The interview results with 79 participants (93%) stated that they had gained knowledge about international standard articles that had these characteristics; interesting topics, strong gap analysis, methods that are detailed and have novelty, and discussion that has a clear novelty.

Abstract

Corrosion can also be defined as the forced destruction of metal by the surrounding medium which is usually a liquid (corrosive agent). Corrosion prevention processes can be carried out, including by coating the metal surface, cathodic protection, adding corrosion inhibitors and so on. Several types of inhibitors that have been widely used in industrial applications are synthetic chemical inhibitors. However, the compounds of inhibitors are environmentally unfriendly, toxic and expensive. To overcome this problem, it is necessary to develop an environmentally friendly alternative corrosion inhibitor or better known as a green inhibitor. This research aims to test the effectiveness of using a combination of lime (Citrus aurantifolia.), Lerak (Sapindus rarak) and jasmine flower (Jasminum nudiflorum) extracts as an environmentally friendly corrosion inhibitor. The results obtained were inhibitors in the form of a combination which were added to the corrosive medium HCl which could reduce the rate of aluminum corrosion. This research also shows that time and concentration influence the corrosion rate. A higher concentration (200 ppm) has a greater inhibitory power than a concentration of 100 ppm. The best inhibitory power is found in 200 ppm inhibitor with a soaking time of 20 minutes

Abstract

This research is a classroom action research that aims to improve students' critical thinking skills through the application of the Discovery Learning learning model. This research was conducted in class VIII G of SMP Negeri 20 Semarang in the even semester of the 2022/2023 academic year with 32 students. This research was conducted in three cycles. Data obtained based on the results of observations and tests. Data collection was carried out using descriptive comparative statistical analysis. The research subjects were class VIII G with a total of 32 students. The results of the first cycle of research showed that the students' critical thinking skills were in the very high category 6.25%, the high category was 12.50%, the medium category was 62.50%, and the low category was 18.75%. In cycle II the increase was shown from the students' critical thinking skills in the very high category 40.62%, the high category 37.50%, the medium category 15.62%, the low category 6.25%, and the very low category did not exist. In cycle III the increase was shown from the students' critical thinking skills in the very high category 65.62%, the high category 28.12%, and the medium category 6.25%. The results showed that the Discovery learning model was proven to be able to improve students' critical thinking skills, where the indicator of the success of this study was an increase in the average value of mastery of critical thinking skills during learning in each cycle. Thus it can be concluded that the use of the Discovery Learning learning model can improve critical thinking skills which have an impact on improving student learning outcomes.

Abstract

The increasing demand for renewable energy necessitates sustainable alternatives such as biochar briquettes derived from agricultural waste. This study aims to optimize the production process and evaluate the physical, mechanical, and combustion properties of biochar briquettes made from corn residues, rice husks, and coconut shells. The methodology includes biomass carbonization, binder ratio optimization, and systematic testing of key quality parameters such as moisture content, density, ash content, and calorific value. Results indicate that an optimal biomass-to-binder ratio yields a high calorific value (7,192 kcal/kg) and low ash content (3.57%), enhancing combustion efficiency. Maintaining moisture content below 10% enhances ignition and prolongs burning time. These findings highlight biochar briquettes' role in carbon sequestration, biomass conversion, and sustainable waste management, supporting the circular economy and reducing environmental pollution. Biochar briquettes offer a clean, accessible energy solution, contributing to global energy security and climate change mitigation.

Abstract

This study aimed to determine the extent to which pre-service science teachers at four universities had mastered the TPACK components and the differences between universities. A comparative descriptive design and a quantitative research method were employed. Data were collected using a 68-item multiple-choice test based on the TPACK framework, which included the following seven core components: CK, PK, TK, PCK, TCK, TPK, and TPACK. The study used a purposive sampling technique, involving 243 pre-service science teachers from the four universities. Descriptive statistics, ANOVA, and the Post Hoc Tukey test were employed to analyze the data and identify significant differences among the universities. The results show that students generally have a 82.1% were categorized as Medium, 14.3% as High, and 3.6% as Low of TPACK proficiency, with none falling into the “Very High” or “Very Low” categories. Major differences were observed in CK, PK, PCK, and TCK, with University 1 attaining the highest overall TPACK scores (though CK was comparatively its weakest component) and University 2 scoring markedly lower. These findings suggest that teacher education programs should strengthen the balanced development of CK, PK, and TK within the curriculum and foster inter-university collaboration to close the TPACK mastery gap identified in this study.
