Abstract

The activity of using mercury in gold mining in Alue Baro Village, Meukek District is carried out freely so that it has a negative impact on the environment and the health of the miners. This study aims to determine the level of mercury in the hair of artisanal gold miners in Alue Baro village by referring to the reference that has been set by WHO. The data sample collection was carried out by taking 6 hair samples from the Alue Baro village gold miners who were selected with various types of work, namely gold processing, waste processing and waste waste until the time of the interview with a minimum working period of 1 year with sample codes R1, R2, R3, R4, R5 and R6 as control samples. The six samples were analyzed using Atomic Absorption Spectrophotometry equipped with a Mercury Analyzer which showed results, respectively, 1.01; 2.38; 1.65; 1.35; 1.66; and 0.64 ppm. The results of this study indicate that all hair samples have mercury levels above the mercury threshold that has been set by WHO, namely 1 ppm. High levels of mercury in hair samples were analyzed on exposure to mercury. Further research was conducted to analyze other metals contained in the hair of gold miners in Alue Baro village

Abstract

Experiments are an important part of the chemistry curriculum. An indicator in the form of a synthesis indicator is commonly used in acid-base materials experiments. The usage of synthetic indicators can result in waste that is both environmentally harmful and costly. The butterfly pea flower is one of the plants that contains anthocyanins, which have the potential to be used as an alternative indication of natural acids and bases. The study aims to determine the acid and base material curriculum and competency indicators, as well as the potential of butterfly pea flower extract as a substitute for synthesis indicators and the practicality of butterfly pea flower extract as a chemical experimental design in SMA/MA. This study employs a descriptive qualitative research method that includes literature review, observation, experimentation, and interviewing. The results showed that the relationship between acid-base materials and experiments was the determination of natural materials as acid-base indicators, the pH of the solution, the identification of acid-base properties, and acid-base titration. The butterfly pea flower indicator was produced from maceration extraction using 96% ethanol as the solvent. The butterfly pea flower indicator gives pink color at pH 1-2, reddish purple at pH 3, light purple at pH 4-5, turquoise at pH 6, bluish green at pH 7, light blue at pH 8-9, green at pH 10, yellowish green at pH 11, greenish yellow at pH 12-13, and yellow at pH 14. The titration step showed that butterfly pea flower indicators could replace synthetic indicators, namely phenolphthalein and methyl orange. Based on the analysis, the butterfly pea flower indicator can be used as an alternative indicator in acid base titration and an alternative experimental design in schools.

Abstract

Measuring the ability of teachers is part of the evaluation in the national education system. The development of the instrument in the form of essay questions has become an alternative because the instrument is considered to have better authenticity than the form of multiple choice questions. The implications of using the essay instrument were scored consistency and efficient resources. The purpose of this study was to examine the inter-rater reliability between the automated essay scoring system and human raters in measuring teachers’ knowledge using the essay instrument. The research was conducted randomly with 200 junior high school science teachers. The quantitative method design was applied to investigate the intra-class correlation coefficient (ICC) and Pearson's correlation (r) as indicators of the ability of automated essay scoring (UKARA) that had been used. The main data in this study were test answers from participants in the form of limited essay answers that have been distributed online. The inter-rater reliability coefficient between the UKARA and the human rater in this study was in the high category (more than 0.7) for all items or means that the score given by UKARA has a strong correlation with the score given by human rater. These results mean that UKARA has adequate capability as an automated essay scoring system on the measurement of science teacher knowledge.

Abstract

Descriptive research on the study of the scientific literacy profile of students and their learning at SMP Kota Banda Aceh, aims to examine the extent to which aspects of scientific literacy according to PISA 2018 are internalized in the junior high school science learning process. In addition, this study also examines its impact on students' scientific literacy. Research data to reveal the emergence of aspects of scientific literacy in planning learning, implementation of learning, and evaluation of learning for junior high school students in Banda Aceh on science subjects. collected through an instrument that refers to the 2015 Program for International Student Assessment (PISA) framework. The data collection technique was carried out through observation, surveys, and content analysis. The research participants involved 9 junior high schools from 9 sub-districts throughout the city of Banda Aceh, each sub-district selected 1 school. The total participants involved were 135 students. The results showed that for the Planning component, the Knowledge Aspect was presented at the largest 35.9% but the aspect that was dominated by the competence aspect for indicators explained the phenomenon scientifically. In the Implementation component, the largest 44.8% of the Knowledge Aspect is presented and it is also dominated by the knowledge aspect for the epistemic knowledge indicator. In the Evaluation component, the Context Aspect is presented at 41.2% which is dominated by the competence aspect for indicators of interpreting scientific data and evidence. The scientific literacy profile in answering the 2015 PISA questions only 1.48% of students were able to answer up to level 2. This shows that the scientific literacy profile of Banda Aceh Junior High School students is still relatively low. The practice of learning science does not contribute much to the achievement of scientific literacy for junior high school students in Banda Aceh

Abstract

Salinity is the amount of salt contained or dissolved in water or soil. Salinity can cause the change of physical characteristics of soil, especially in coastal area, that affects human daily activities, including agriculture. Baitussalam District (Kecamatan Baitussalam) is one of the districts that was hit most devastatingly by the Indian Ocean Tsunami 2004 as well as has large population with potential agricultural prospect in Aceh Besar Region (Kabupaten Aceh Besar). This research aims to identify the soil salinity level in the Baitussalam District. The sampling technique uses descriptive methodology with scalable quantitative approach in the chosen sampling areas. 26 sampling spots have been chosen according to mathematical calculation. Quantitative method is used to analyze the result in this research. Furthermore, conductivity measurement is done through induction electromagnetic method, using Geonics EM38 and to identify the soil salinity level, analysis of soil texture is conducted in the laboratory. As the result, the electrical conductivity measurement shows varying values. The minimum conductivity value is 0,004 dS/m, taken at spot T 004 in Lam Ujong Village (Desa Lam Ujong). Whereas the maximum conductivity value reaches 10,31 dS/m, taken at spot T 003 in Labuy Village. The soil salinity in the 26 sampling spots in Baitussalam District demonstrates an average level, with a value of ECa 2-4 dS/m. The result of this research is expected to be a parameter to control and develop the activities, especially for agricultural activities, in the coastal area in Aceh Besar Region, and in Baitussalam district in particular.

Abstract

A good understanding of the three levels of chemical representations is required to understand the concepts of chemical bonding. However, most students are difficult to understand chemical bonding topics due to the abstract concepts and the learning resources used don’t fully integrate the three levels of chemical representations. Therefore, learning resources that cover all of the chemical representations and visualize the abstract concepts are needed. The purpose of this study is to determine the level of validity and responses of teachers and students to the developed chemical bonding module based on multiple representations assisted by AR  technology. This type of research is research and development that refers to the ADDIE instructional design model. The instrument used in this research is the sheet of validity and the response questionnaire. The collected data were analyzed using percentage analysis techniques. The product of this research is a chemical bond module based on multiple representations and an augmented reality chemistry simulator of chemical bonding application. The results of the expert's validation show that the average percentage of content, media, and language validity respectively are 99, 95, and 97% with very valid criteria, so that it can be used in the learning process. In addition, teachers and students gave a very good response to the product with a percentage of 90 and 87% consecutively. These findings indicate that the modules assisted by AR technology could support the chemistry teachers to explain the chemical bonding topic and help students visualize the abstract concepts of chemical bonds

Abstract

Physics is a science that discusses every result of studying the answers to the question of causes, as well as natural phenomena that can occur. The most complex problem experienced by students is the lack of skills in solving physics problems for students. The low problem solving ability of students resulted in the ability to master the basic concepts of students. This study aimed to observe the escalation of problem solving skills after the implementation of the PIL learning model in physics at MAN 6 Aceh Besar. This research is included in the type of quasi-experimental research by designing a nonequivalent control group using 2 class samples as the experimental class and the control class. The population of this study was 64 students with 43 students participating in the study. Purposive sampling method was used in order to select the study sample. The collected data was analyzed using an independent-t test technique. This study observed that PIL learning models gave a positive impact to student autonomous learning and problem solving skills. The escalation of both variables was observed from the N-Gain score. On the problem solving skills, the control group reached 0.50 N-Gain score and the eksperimen group reached 0.79.
