Abstract

The skin of the thorny palm has been empirically recognized by some people as a traditional medicine for beauty, antimicrobial, and antidiabetic. Compounds that act as treatment in the skin of the thorny palm is flavonoids. The study aims to determine the total flavonoid of the thorny palm rind extract based on differences in the drying of simplicia. The simplicia drying method used was oven-dry, direct sunlight, indirect sunlight, and air dry and fresh samples as control. Extraction using the maceration method with ethanol p.a. solvent. Determination of total flavonoid levels from the extract of thorny palm rind using the UV-Vis spectrophotometric method with quercetin standard solution. The qualitative test results showed that the skin of the thorny palm contains flavonoids after the addition of 1% AlCl3. The total flavonoid content in the fresh sample was 0.00342%, direct sunlight was 0.00350%, oven-dry was 0.00340%, dry air was 0.00357%, and indirect sunlight was 0.00361%. Therefore, it can be concluded that the highest flavonoid content in the extract of thorny palm rind is found in the indirect sun drying method.

Abstract

One of the sea potentials in Aceh is seaweed. Seaweed contains secondary metabolites and antioxidants that are very well consumed because it can act as an antidote/protector from the free radicals. This study aimed to determine the secondary metabolite content and antioxidant activity of seaweed in Aceh.The seaweed that has been macerated then screened for phytochemicals and tested for antioxidant activity by using the DPPH method. The seaweed species found were Gracillaria verrucosa, Sargassum sp., and Chaetomorpha antennina. The results of this study indicated that Gracillaria verrucosa, Sargassum sp., and Chaetomorpha antennina seaweeds were contained by alkaloids and steroids. Flavonoid and saponins were only detected in the types of seaweed Gracillaria verrucosa and Sargassum sp. It was also found that the higher the concentration of the extract, the higher the percentage of IC50 against free radicals. The Sargassum sp. has a stable percentage of inhibition at a 2-10 ppm concentration, so it is recommended in this study to be considered cultivated in Aceh.

Abstract

Students with high self-efficacy mean having high motivation, awareness and self-regulation so that it is expected to have a positive effect on learning outcomes including numeracy skills, self-efficacy can be influenced by internal factors such as gender. This study aims to analyze differences in self-efficacy students' and numeracy literacy skills based on gender, the relationship between self-efficacy and students' numeracy literacy skills based on gender and the effect of  self-efficacy on students' numeracy literacy skills. The method used is descriptive method. The sample of this study was 88 students consisting of 44 male students and 44 female students of VIII SMP from four schools in North Aceh and Lhokseumawe who were participants in the 2021 national assessment. Data collection used questionnaire instrument self-efficacy containing 45 statement items and 36 numeracy literacy questions that are already valid and in accordance with the AN question grid. The results showed that the significance value was 0.288 > 0.005 indicating that there was no significant difference between the self-efficacy of male and female students, (2) the significance value was 0.652 > 0.05, meaning that there was no significant difference between literacy abilities numeracy men and female (3) self-efficacy and literacy numeracy students have a relationship with the degree of correlation is high and positively related (4) the coefficient of determination (R2) of 0.489 explains that the influence of self-efficacy with literacy numeracy student is 48.9%.

Abstract

This study aims to describe 1) the validity, reliability, and distribution of research instrument data; 2) students' perceptions of the ability to understand chemical concepts in online learning based on indicators of stimulus, response, and evaluation of learning outcomes. Descriptive quantitative research method, data collection on 19 SMAITA students was selected by purposive sampling. Perception data was obtained through a questionnaire in the form of a google form containing 3 indicators and post-test data in the form of UTS scores. The results showed that the questionnaire instrument was valid and reliable as evidenced by the corrected item-total correlation of 9 statements, each of which had a value of more than 0.3 and a reliability value of 0.722 and the data were normally distributed. Perceptions of the ability to understand chemical concepts in online learning based on stimulus indicators 39.5% agree, 11.85% strongly agree and 47.32% are neutral. Perception-based on response indicators 63.17% agree 5.3% strongly agree. And Perception based on evaluation indicators 81.6% agree 13.15% strongly agree. The majority of students actively ask questions when there are unclear questions, can better understand the material after having discussions, become more confident when answering UTS questions, feel suitable for online chemistry learning during the pandemic but online learning is not accompanied by other media such as youtube which is less attractive. The results of this study can be used as a scientific reference for the online learning process.

Abstract

The use of local culture in the community can be used as a source of learning science in schools. This is one of the characteristics of the 2013 curriculum. However, the availability of local culture-oriented or ethnoscience-oriented chemistry books is not yet available in several schools in Pekalongan. This research aims to develop an ethnoscience-oriented chemical enrichment book by raising the typical food culture of Pekalongan. This research uses the Research and Development (R & D) method and the ADDIE (Analyze, Design, Development, Implement, and Evaluate) model. Data collection techniques use interviews, validation, and questionnaires. The results of data validation processing used the Guttman scale, and the response data used a Likert scale. This study produced an ethnoscience-oriented chemical enrichment book by raising the typical food culture of Pekalongan consisting of 5 special food items and 7 chemical materials and validation by 4 validators with a percentage of 100% from material experts and 93.33% from media experts. In addition, the responses of teachers and students of SMA Islam YMI and SMA PGRI 2 Kajen were obtained with an average percentage of 90.25% from teachers and 88.54% from students. Thus, this book is included in the very good category and is suitable for use as additional chemical teaching materials. Keywords: enrichment book; ethnoscience; typical Pekalongan food

Abstract

This research is entitled "Study of Organic and Anorganic Waste Processing at the Unit Bank Sampah of Badan Usaha Milik Gampong (BUMG) Blang Krueng". One of the environmental problems that still need to be resolved is the waste problem. In general, people immediately throw away or burn garbage without considering the causes and effects that will arise after that. So, one of the waste management methods is organic and inorganic based waste management as practiced by the Waste Bank unit at BUMG Blang Krueng. The formulation of the problem in this study is how to manage organic and inorganic waste in the BUMG Blang Krueng Unit Bank Sampah. This research is a field study research. This is a type of qualitative research using the method of observation, interview and documentation in data collection. Data analysis was carried out descriptively from the results of observational data and documentation obtained. Based on the results of the study, it was found that the BUMG Blang Krueng Unit Bank Sampah had processed organic waste with a composting system so that compost and liquid fertilizers were obtained, as well as inorganic fertilizer processing and recycled materials such as plastic ore and other selling value materials were obtained. Keywords: 1. Processing 2, Organic Waste 3. Inorganic Waste
