<![CDATA[This study was conducted to create and validate the instruments test of prechemistry teacher’s knowledge about health and safety work in laboratory. This instrument will be used to obtain information about prechemistry teacher’s knowledge about health and safety work in laboratory. This research has been conducted using Research and Development (R & D) design that was developed by adopting 4D development model consisting of 4 stages: define, design, develop and dissemination. However, this research only reached the develop stage. Data analysis was performed to test the validity and reliability of the tests. Data processing was performed using IBM-SPSS 20 software. The results of this study showed that the test was valid and was feasible to implement based on the CVI value of 0.847. The reliability test of prechemistry teacher’s knowledge about health and safety work in laboratory was obtained at 0.766, its mean that the reliability of the tests was classified as in high category. Thus this instrument can be used to determine the level of prechemistry teacher’s knowledge about health and safety work in laboratory. Although there are some parts of the instrument need to be revised again. Keywords : instrument, healthy and safety work, laboratory, reliability, validity]]>

<![CDATA[Abstract This research aimed at knowing whether there was a correlation between students’ learning style and their learning achievement. It was a correlational research. Collecting the data was done through learning style questionnaire, cognitive learning achievement test, and documentation. The subjects of this research were the students at Senior High School of Tri Bhakti Pekanbaru, and the object was the correlation between students’ learning style and their learning achievement on Chemical Equilibrium lesson. The samples were the eleventh-grade students of Natural Science that were 40 students. Total sampling technique was used in this research. The data were processed and analyzed by using Pearson product moment correlational test formula. Based on the research findings and data analyses, Sig. (2-tailed) score between students’ learning style and their learning achievement was 0.001 and it was lower than 0.05 (0.001<0.05), it meant that there was a positive correlation between students’ learning style and their learning achievement. The score of robserved of the correlation between students’ learning style and their learning achievement was 0.498 and it was higher than rtable 0.312 at 5% significant level (0.498>0.312), so it could be concluded that Ha was accepted and H0 was rejected (there was a correlation between students’ learning style and their learning achievement). The majority of the students had visual learning style type with 58% percentage, the percentage of students having auditory learning style was 27%, and the percentage of students having kinesthetic learning style was 15%. If these results were interpreted to the guideline table, the score 0.498 was between 0.40 and 0.70, and it meant that the correlation between students’ learning style and their learning achievement was medium or enough.]]>

<![CDATA[It was a quasi-experimental research with pretest and posttest design, and it was conducted to two classes—experimental and control groups. This research was instigated by the low of student chemistry learning achievement at the eleventh grade of Natural Science of State Senior High School 5 Pekanbaru. This research aimed at knowing the effect of implementing Guided Inquiry learning model with module toward student learning achievement on Reaction Rate lesson at the eleventh grade of Natural Science of State Senior High School 5 Pekanbaru. The samples were two the eleventh-grade classes of Natural Science having the same homogeneity level. The eleventh-grade students of Natural Science 5 were the experimental group and the students of Natural Science 2 were the control group. Simple random sampling technique was used in this research. The techniques of collecting the data were interview, preliminary data test that was homogeneity test, final data tests that were pretest and posttest, and documentation. The analysis results showed that the posttest mean score of the experimental group was 85.63 and the control group was 78.75. Final data analysis that t-test was used showed that the score of tobserved 3.08 was higher than ttable 2.00 at 5% significant level, so H0 was rejected and Ha was accepted. It meant that there was an effect of implementing Guided Inquiry learning model with module toward student learning achievement on Reaction Rate lesson at the eleventh grade of Natural Science of State Senior High School 5 Pekanbaru, and the coefficient of effect was 14%]]>

<![CDATA[Vitamin C is one of the vitamins that the body needs to increase immunity in warding off all forms of disease. One of the fruits that contain vitamin C is srikaya fruit. Srikaya fruit is a plant belonging to the genus Annona originating from the tropics. Srikaya fruit is analyzed for its vitamin C content in order to increase the immunity of the community during the COVID-19 pandemic. The method used is a laboratory experiment with the iodometric method. The result is that srikaya fruit contains a fairly high amount of vitamin C, with the average vitamin C levels in the srikaya fruit sample being 2.58%, 2.503% and 2.66%, respectively, while the average vitamin C content in the srikaya fruit sample is 2.581%. And during this pandemic, we should consume a lot of food and fruit with vitamin C to increase the body's immunity, so that it can be developed to the next stage of further and more effective research.]]>

<![CDATA[Basil is known to contain chemical flavonoids, namely orientin and vicenin where these two compounds can protect the body from the effects of radiation.The purpose of this study was to determine the toxicity of the ethanol extract of basil leaves (Ocimum Scantum Linn). Artemia salina Leach larvae using the Brine Shrimp lethality Test (BSLT) method. This study used 3 concentrations, each of which was carried out in triples. The concentrations are 1000 ppm, 100 ppm, 10 ppm. 90 Artemia salina Leach larvae were used. Then observations were made for 24 hours. Then counted the number of shrimp larvae that died after 24 hours. The results were calculated by probit analysis and calculated LC50, obtained LC50 = 21.0523 ppm. So it can be concluded that basil leaves have toxic potential. Because the value of LC50 < 1000 ppm.]]>
