Abstract

Research has been conducted to analyze the content of heavy metals (Pb, Cd, Mn) in lipstick circulating in Batusangkar Market. Samples are lipsticks that are registered and not registered with BPOM with various brands, colors and prices sold in the batusangkar market and totaling 10 samples. The sample was destroyed using a mixture of nitric acid and hydrogen peroxide. Furthermore, the content of Pb, Cd and Mn was measured using Atomic Absorption Spectrophotometry (AAS). Based on the results of the analysis, the Pb content in the sample ranged from -6.875 mg/kg to 2.0305 mg/kg, Cd content 0.18 mg/kg to 0.52 mg/kmg/kg, Mn content -4.60 mg/kg up to 149.59 mg/kg. Lead was found in 4 out of 10 lipstick samples, heavy metal Cd was found in all lipstick samples and manganese was found in 8 out of 10 lipstick samples. Based on these results, it can be concluded that the heavy metal content in the electrical sample is below the specified limit so that it meets the requirements of the Regulation of the Head of the POM No. 17 of 2014 concerning requirements for microbial and heavy metal contamination in cosmetics.

Abstract

This study aims to improve the learning outcomes of students using the video of the stop motion animation as an offiler learning media in the reciprocal teaching learning model on chemical bond material in SMA Negeri 4 Ambon. This research is quantitative research. The sample in this study is class X IPA-2 with the number of students as many as 30 people. This study lasted for 3 meetings on chemical ties, technique of data collection in this study included test techniques, LKS, observation using cognitive aspect sheets, observation sheet of affective aspects (attitude) and observation sheet of psychomotor aspects (skills). The Pretest is given treatment to measure students’ initial understanding while, the posttest is given to measure students’ final understanding after being given treatment. From the results of data analysis obtained showing the learning outcomes of class X IPA-2 students have achieved minimum completeness criteria (KKM), with the final value obtained is the excellent qualification of 1 student (3.3%), qualification of both 4 students (13.3%), qualification is quite 23 students (76.7%) and qualifying 2 less than 6 students (6.7%). The results of research data analysis through N-Gain calculations showed an increase in student learning outcomes obtained by 7 students (23.3%) in high categories and 23 students (76.7%) in medium category, for the average results of N-Gain scores all students obtained by 0.68 which are in medium category. From the results obtained all students meet the assessment criteria despite being in different qualifications. The results showed an increase in the use of the learning method of animation video stop motion can improve student learning outcomes.

Abstract

Salah satu penyebab pencemaran lingkungan oleh merkuri adalah pembuangan tailing pengolahan emas yang diolah secara amalgamasi. Perairan Desa Batuboy Teluk Kayeli merupakan salah satu perairan yang diduga telah mengalami pencemaran logam berat. Tujuan penelitian ini adalah untuk mengetahui kandungan merkuri dan ukuran partikel dari sedimen di Desa Batuboy, Pulau Buru. Manfaat dari penelitian ini adalah untuk memberi bukti dan informasi ilmiah bagi masyarakat desa Batuboy tentang kandungan merkuri dalam sedimen. Ukuran butir sedimen diukur dengan menggunakan Sieve Shaker dan sampel dianalisis dengan menggunakan Mercury Analyzer. Hasil penelitian menunjukan bahwa ukuran butir partikel sedimen adalah gravel berkisar antara 2.29-5.90%, pasir 95.48-97.25%, dan lumpur 0.82-7.23%. Kadar merkuri (Hg) pada sedimen di semua sampel menunjukkan bahwa kandungan merkuri (Hg) pada sedimen di Desa Batuboy belum melewati ambang batas yang ditetapkan oleh US EPA sebesar 0,2 mg/kg.

Abstract

The purpose of this study was to determine the application of science process skills to improving student learning outcomes on the concept of electrolyte and nonelectrolyte solutions for class X SMA Negeri 26 Central Maluku and to determine student responses to learning by using the laboratory. The type of research used is descriptive quantitative research design with one group pretest-posttest design. The research sample was 25 students of class X MIA-1 SMA Negeri 26 Maluku Tengah. Data was collected using test instruments and non-test instruments. The results showed that all students (100%) had reached the KKM. To find out the increase in student learning outcomes, it is calculated using the normalized gain formula (n-gain) where 8 students (32%) are in high qualification and 17 students (68%) are in medium qualification, with an average value of n-gain of 0.7 with a percentage of 70%. For student responses to learning by utilizing laboratories in the form of practicum activities, 17 students (68%) were in the strongly agree qualification, 8 students (32%) were in the agree qualification. Thus the application of science process skills and the use of laboratories has a positive effect on improving learning outcomes.

Abstract

This study aims to determine the increase in students' science process skills by applying an ethnoscience-based inquiry learning model to colloid system material from a public high school in West Seram. The type of research used is descriptive-quantitative. The sample used in this research was 30 students in class XI IPA. Data collection techniques in this study were test techniques in the form of a pre-test and a post-test. The results showed that the application of the ethnoscience-based inquiry learning model succeeded in improving students' science process skills, with an increased score calculated based on the results: the average value before learning was 26.29 and increased after learning with an average value of 80.50. The average value of N-gain is 0.74, indicating an increase in students' science process skills in the high category. Encouraging chemistry teachers to explore other ethnosciences to teach colloid systems is necessary.

Abstract

Palmyra palm is a species of palmae that grows a lot on Kisar Island where all parts of the plant can be utilized. However, the palmyra palm fruit shell has not been used and that is only thrown away. In this study, palmyra palm fruit shell were made as activated carbon and were characterized using XRD to determine the crystallinity properties of the palmyra palm fruit shell activated carbon and adsorption test was carried out to determine the capacity and efficiency of activated carbon adsorption to methyl red dye. The production of palmyra palm fruit shell activated carbon is carried out through the carbonization stage at 300°C for 1 hour, and followed by chemical activation using H3PO4 10% solution for 24 hours. The results of the analysis using XRD showed that the activated carbon of the palmyra palm fruit shell formed peaks with the highest intensity at diffraction angles of 2θ = 26.5241° and 27.6274° with d-spacing values ​​(Å) = 3.36059 and 3.22884, which are characteristic peaks of carbon and are amorphous. The adsorption of methyl red 20 ppm use batch method, with various contact times of 5, 10, 15, 20, 25, and 30 minutes. The results of showed that on 15 minutes was the optimal time, with 0.25 gram mass of the adsorbent and the adsorption capacity and adsorption efficiency was 0.87 mg/g and 44.3%, respectively.
