<![CDATA[The purpose of this study was to determine the validity and effectiveness of visual flash media card on the material living creatures interaction with the environment that will be developed. Research development refers to the steps of learning development model of Plomp which consists of five stages: stage a preliminary investigation (preliminary investigation), stage design (design), the realization phase of construction (realization of construction), the stage of the test, evaluation and revision (test, evaluation and revition) and the implementation phase (implementation). The resulting product is a visual media flash card. The research instrumen used is divided into two, namely the validity of the instrumen that includes sheets of flash card validation visual media and the effectiveness of the instrumen includes questionnaire responses of learners and the learning outcomes test. Subjects in this study are students of class VII SMP Negeri 1 Palangga the academic year 2015/2016 as many as 43 people. Data collection techniques used were questionnaires and learning outcomes test. Analysis validation of visual media flash card by two validators were obtained an average yield of 4, which means valid. Based on the analysis of questionnaire responses of learners with a result 86% of students stated that visual media flash card either once used in the learning process. Based on the test of learning outcomes of students grade VII obtained results that 40 students achieve mastery value of 70 with a percentage 93%. Based on the result it can be concluded that the visual media flash card effective to be used in science learning for material interaction between living creatures with their environment.]]>

<![CDATA[The paper of this research is to discuss SITR mathematical model for the Spread of tuberculosis disease. Thedata used is secondary data of tuberculosis patients obtained from Public Health Office of South Sulawesi Province in 2015. The discussion starts from constructing an SITR mathematical model of tuberculosis disease, determining the equilibrium point, thenlook ing for stability analysis of equilibrium point, determining the basic reproduction value (Ro), mak ing model simulation, and interpreting them. In this paper we obtained an SITR mathematical model for tuberculosis, disease-free and endemic equilibriumpoints of the SITR model, the global stability of disease-free and endemic equilibrium from the SITR model with the basic reproduction value Ro = 1,04336331 indicates that tuberculosis disease is endemic.]]>

<![CDATA[P. xylostella is an important pest on cabbage plants in Merauke Regency because it can cause serious damage to cabbage plants at the start of planting. Severe attacks can damage the growing points of the cabbage plants, preventing the plants from forming heads. This study aims to determine the population and intensity of attack of P. xylostella on cabbage plants in Merauke Regency. The research was carried out in Tanah Miring District and Merauke District, Merauke Regency, Papua Province in September-December 2020. Observations were made on cabbage plantations that were two weeks old after being 2 transplanted from the nursery, then 10 plots were determined. Observations were made six times in the morning with one week intervals. The highest population average of 1.11 individuals was found in 6 WAP and the lowest population was in 1 MST of 0.11 individuals. The highest average damage was found at the 6 MST observation time of 59.17%, while the light damage was found at 1 MST of 8.33%. This shows that the low population of P. xylostella can cause damage to up to 8.33% of cabbage plants. The percentage of attack by P. Xylostella on cabbage in Tanah Miring District was 43.7%, while in Merauke District it was 15.5%. The high attack in Tanah Miring District is due to the availability of host plants throughout the growing season.]]>

<![CDATA[According to Purwanto (2018), research instruments are tools used to collect data in research. The purpose of this study was to test a valid, consistent and reliable critical thinking instrument. In this study, critical thinking consists of five constructs, namely: (1) giving a simple explanation; (2) developing basic skills; (3) summarizing; (4) giving a more detailed explanation; and (5) deciding on the next strategy. The study was designed as a survey research with 50 respondents, consisting of 3 experts/lecturers, 5 teachers and 42 students selected through stratified and random sampling techniques. Data were analyzed using SPSS Version 23.00 for Windows to test internal consistency using Cronbach Alpha. The results showed that all items in the questionnaire were valid and reliable. The average Cronbach alpha reliability score is high (0.897 > 0.6) and each statement has a high score (0.784 to 0.890). Therefore, these figures indicate that this study has developed a critical thinking instrument.]]>

<![CDATA[The aim of this research was to know the difference of ethanol extract and extract of ethyl acetate of pepper leaf (Piper nigrum L) to antimicrobial activity of Staphylococcua aureus, Escherichia coli and Candida albicans. The maceration method has been used to extract the pepper leaf by using two solvents ie 70% ethanol and ethyl acetate. The extract results were then tested for antimicrobial activity. The result of pepper ethanol extract obtainedby the higher yield was 24,64% compared with ethyl acetate extract 9,18%. Leaf pepper ethanol extract had higher antimicrobial activity than pepper acetate leaves extract against Staphylococcua aureus, and Escherichia coli but did not inhibit Candida albicans fungi at concentration of 10%]]>
