Abstract

Lithium ions (3)  is a particle that has a single electron and is formed because lithium metal loses 2 of its 3 valence electrons. Probability is the square modulus of a wave function. Electron probability is a description of the discovery of electrons in space. This study aims to determine the probability value of electron momentum of Lithium ion (3). This type of research is non-experimental research in the form of developing existing theories with theoretical research methods. When viewed from the main orbital quantum value, the greater the probability value or the easier the electron is found at a larger quantum number. When viewed from the level of the probability interval, the greater the probability interval, the greater the main quantum value. In accordance with the theory which states that the large main quantum number n and orbital quantum l result in the probability value of Lithium ions getting bigger.

Abstract

Various compounds and extracts obtained from a wide variety of plants can be employed as natural antioxidants in cosmetics applications. Patchouli oil (Pogostemon cablin Benth.) and drumstick oil (Moringa oleifera) have the ability to fight free radicals and keep skin hydrated, making them excellent candidates for usage as an active component in cosmetic goods like body cream. This research aims to determine the physical quality of a body cream formulation by subjecting it to an accelerated stability test technique for seven cycles. The preparation was evaluated in each cycle, and the results were analyzed using student's t-test. The evaluation results of body cream preparation showed that there was no significant difference (p>0.05) in the preparation during each cycle. As a result, the formulation of the body cream remained stable throughout the storage term of at least six months, which indicates that it can be utilized for an entire year when kept at room temperature. After two weeks of application on dry skin, it was demonstrated that the formulation had the capacity to increase the amount of moisture contained in the skin (from 30% to 60%). In conclusion, the formulation is potentially produced as commercial cosmetic product in the future.

Abstract

This study was designed to identify and describe students’ metacognitive thinking process in solving compound polarity based on academic ability level. Two hundred and eighty-four high school students in Indonesia participated in the study. Students are classified into high, middle and low academic ability groups based on field notes, student academic data, compound polarity problem-solving test (CPPST) scores and teacher suggestions. Six selected students from each group were designated as research subjects and then interviewed in depth to explore their metacognitive thinking processes. CPPST answer sheets and interview transcripts were analyzed using summative content analysis and tested for validity by data triangulation. The results showed that the students with high and medium academic ability level carry out metacognitive thinking processes in the dimensions of planning, monitoring and reflection in solving compound polarity problems, where the metacognitive thinking processes of students with high academic ability are more varied than students with middle academic ability. Students with low academic ability only carry out the dimensions of planning and monitoring. Therefore, teachers need to train students' metacognitive skills in solving problems and get used to applying metacognitively in each given problem solving so that students are trained to solve problems systematically, carefully and thoroughly, and manage time properly in order to obtain the expected learning achievement.

Abstract

The high burden of final waste management causes pollution due to the low contribution of prevention at the source. The composition of Indonesia's food waste reaches 40.62%. Proper food waste management has become a challenge because the habit of segregation at the household level is still low. Home-composting is an option for management from sources with technology that is easy to operate, but its use still needs to be improved. This study looks at the factors influencing people's behaviour in composting-based household food waste management. The objective of this study is to analyze the variables of attitudes, subjective norms, and behavioural control, which affect behaviour in home-composting activities, using the theory of planned behaviour model. A quantitative approache with multiple regression analysis was used in the study. Subjective norms and behavioural control significantly (p < 0.05) influence home-composting behaviour, while attitudes (p > 0.05) do not influence home-composting.

Abstract

Catfish (Clarias sp.) is one of the many fishery biota that has animal protein which is much loved by Indonesian people. One way to develop environmentally friendly catfish cultivation is through the implementation of an aquaponic biofilter system. This research aims to analyze physical, chemical, and biological water quality parameters in catfish cultivation with and without aquaponics, to obtain a description of the non-specific immune system which is analyzed from the conditions of phagocytic activity of catfish cultivated with and without aquaponics. The method used is by taking samples ten times per week by taking water quality parameters as well as blood samples of catfish raised in ponds with and without aquaponics. The analysis used is the unpaired T-test. Based on the results obtained, it was concluded that all parameters showed that the aquaponic cultivation media was better compared to those without aquaponics.

Abstract

Teachers should have different knowledge types including technological, pedagogical, and content to realize effective learning in the digital era. Technological Pedagogical and Content Knowledge (TPCK) is a framework that explains these knowledge types and the interactions between them. It is considered to enable chemistry teachers’ multifaceted teaching. Coping, for this reason, a study to examine chemistry teachers’ level of TPCK is needed. This paper reports the level of chemistry teacher’s TPCK and their perception in terms of teaching stage, gender, and age. The study involved fifty-three students of chemistry education in a public university in Indonesia. A quantitative method was applied to explore their perspective on TPCK. Data were collected through surveys and interviews. The findings showed that the majority of chemistry teachers’ TPCK skills are currently good. They integrate technology into their teaching while conducting online learning due to the COVID-19 pandemic. In terms of teaching stage, age, and gender, provide deep insight into seven indicators of TPCK. However, some indicators still need to be improved, so a TPCK training program for individuals or centralized individuals should be added to the chemistry department program.

Abstract

The purpose of this study was to investigate the impact of using the Problem-Based Learning (PBL) model on learning outcomes in Webbed integrated learning at elementary schools. Webbed integrated learning is an approach that integrates multiple subjects into a single learning theme, while PBL is a learning method that emphasizes real-world problem-solving within the learning context. The research employed an experimental design with a Post-test Only Control Group Design. The sample consisted of third-grade students in Gugus VI, Kuranji District, Padang City, with two groups: an experimental group comprising 20 students and a control group comprising 20 students. The experimental group implemented the PBL model in Webbed integrated learning, while the control group used conventional learning in Webbed integrated learning. Learning outcome data were obtained through written tests that covered cognitive and affective aspects of integrated learning. Data analysis was conducted using an independent t-test to compare the learning outcomes between the experimental and control groups. The results showed a significant difference in the average learning outcomes of Webbed-integrated learning using the PBL model compared to the average learning outcomes of Webbed-integrated learning using conventional learning based on the results of the independent sample t-test, which yielded a sig value of 0.00 < 0.05 and a t-value > t-table with a t-value of 5.463 and a t-table value of 2.024. Therefore, it can be concluded that the use of the PBL model has an impact on learning outcomes in Webbed integrated learning.
