Abstract

Science process skills are one of the components of psychomotor competence, these skills can support student activities to acquire knowledge. In learning activities having science process skills is something that is very important for students. This study aims to measure and find out the concept of applying and understanding science process skills in the science learning process, especially in food testing practicum. This type of research on food test material is qualitative descriptive research. The research was conducted on class VIII students of SMP Muhammadiyah Al-Kautsar PK Kartasura Sukoharjo. In this study, there were two data that were examined, namely the first data from the results of student science process skills observations. The research was conducted through three stages, namely pre-survey, implementation, and drawing conclusions. The second data collection was based on the teacher's knowledge of science process skills and the approach to the science teaching process by using interview techniques with science subject teachers in schools. The data obtained from the research were analyzed using quantitative and qualitative methods. The data shows that the overall understanding and application of students' science process skills based on the results of observations shows a good category, namely 76.3%. The conclusion drawn is that the science process skills approach to SMP Muhammadiyah Al-Kautsar PK students is in a good category. Based on the results of interviews with science teachers, the results show that so far, the lecture method is the method most often encountered and implemented by teachers in learning science. In fact, the implementation of science practicum is very important. In the practicum method, it is hoped that students will be able to interact directly with objects as well as be able to empower various competencies, especially being able to develop science process skills

Abstract

Malnutrition is the primary cause of morbidity and mortality in children. The term of malnutrition includes a state of undernutrition and overnutrition, that is caused by consumption of food that is lacking, poor absorption, or excessive loss of nutrients. To assess the nutritional status of children age 4-6 years old in local village, Bali. This research was a cross-sectional descriptive study with 60 subject which were kindergarten students in Bali and with 60 respondents which were the mother of the subjects. The data collecting technique of this research was purposive sampling, with using questionnaire for respondents and direct measurement for the subjects. Most of the respondents were in normal category based on anthropometry index. We also found the prevalence of over nutrition were higher than undernutrition. Undernutrition status was found more in children with less nutrient intake, normal nutrition status was found more in children with good nutrition intake, while over nutrition status was more dominant in children with high nutrition intake. Most of research subjects which are children age 4-6 years old in local village Bali are on normal category of nutritional status. This result are expected to be a basis in anticipation of further research and for making public health programs

Abstract

The Covid-19 pandemic has caused students to experience learning loss or a slowdown in student learning development in literacy, numeracy, and science. Another pandemic's impact is changing students' behavior and emotions, such as difficulty concentrating during online learning, sensitivity, anxiety, and other excessive worries. In order to overcome learning problems, one strategy from the government is releasing Kurikulum Merdeka, which focuses on Project-based learning. Several studies discussed the difficulties of project learning from the teacher's view, but no data explicitly discusses students' difficulty in implementing project learning. This research aims to identify the challenges and obstacles experienced by students when carrying out project learning. Furthermore, this research is grounded research used as reflection material for teachers in planning and improving the quality of project-based learning. The Project Learning Experience questionnaire was distributed to seven high schools in Kota Bandung, and 592 responses were recorded. From the data findings, students faced challenges in collaborative activities; contributions, time management, problem-solving, teamwork, and investigation techniques due to a lack of self-regulation. Theoretical contributions and implications for educational practices are discussed

Abstract

Thermostable amylase plays a role in the industrial sector because it is resistant to high temperatures, has high enzyme activity in various parameters and is economical in production costs. The thermostable amylase used in industry is stable and thermo activity. Bacteria that produce thermostable amylase can come from hot springs with temperatures above 80°C, such as Semurup hot springs, Kerinci, Jambi province, Indonesia. Semurup hot spring (Jambi) has a temperature of 82°C and a pH of 8.6. This causes variations in the content of organic, inorganic, and mineral compounds in the Semurup hot springs. The varied mineral content causes thermophilic bacteria to survive and the genetic diversity of thermophilic bacteria varies. This study aimed to molecularly identify thermostable amylase-producing thermophilic bacteria by analyzing the 16sRNA gene. Identification of bacteria was carried out by analyzing the 16S rRNA gene of thermophilic bacteria, such as DNA Isolation, DNA Amplification, 16S rRNA Gene Analysis, Alignment, and Phylogenetic Tree. There were 4 different bases between the bacterial isolates MGH3 and Bacillus licheniformis ATCC 14580, namely bases no. 87, 120, 967, and 1374. The difference of 4 bases in the two bacterial isolates already shows that the two isolates have a close kinship. So, most likely the MGH3 bacterial isolate is Bacillus licheniformis strain MGH3.

Abstract

The Indonesian region is affected by the monsoon system, which leads to a rainy season in December-March and a dry season in June-September. Global warming caused by human activities is increasing the risk of extreme climate events like floods, droughts, etc. The study aims to analyze the trends and correlations of extreme temperatures in the South Sumatra coastal area and its relationship with the DMI and Nino 3.4 indices. The four-stage research methodology includes data collection, extreme temperature index calculation, trend detection and correlation analysis with ENSO. Results indicate that the region has seen a rise in temperature, with hot day/night temperatures increasing by 0.26-0.29°C per decade and cold day/night temperatures by 2-3°C per 100-1000 years. A strong correlation was found between the DMI index and daily maximum/minimum temperatures, as well as between the Nino 3.4 index and the Diurnal Temperature Range (DTR). The study projects that nighttime temperatures will increase faster than daytime temperatures in the future, with a proportional correlation between the Nino 3.4 index and extreme temperatures
