The large demand for cayenne pepper makes farmers need to make efforts to increase crop production by increasing the efficiency of using fertilizers. The alternative fertilizer comes from household waste, namely egg shells. This study aims to determine the effect of eggshell organic fertilizer on vegetative growth of cayenne pepper (Capsicum frutescens L.). The research method used was an experimental method using a completely randomized design (CRD) with 6 treatments and 5 replications. The treatments were P0 (control), P1, P2, P3, P4, and P5 respectively, the treatment of eggshell organic fertilizer with a dose of 0; 45; 60; 75; 90; and 105 g. The treatments were given 3 days after transplanting and harvesting the plants 35 days after transplanting. Data for each parameter was tested for normality, homogeneity test, and analyzed by 1 factor ANOVA. Furthermore, the LSD test was carried out to determine the difference in effect between treatments. The best application of eggshell organic fertilizer was P4 treatment for parameters of root length and plant wet weight, respectively, 20.10 cm and 17.96 g, and P5 treatment for parameters of plant height and plant dry weight, respectively 54.80 cm and 3.00 g. The percentage of root length and wet weight of P4 treatment plants to control were 130.52% and 269.67%, respectively, while the percentage of plant height and dry weight of P5 treatment plants to control were 139.79% and 282.49%, respectively. The application of eggshell organic fertilizer can increase the vegetative growth of cayenne pepper.

Background: The ability to think analytically is one part of higher-order thinking skills, which should be owned by students according to the reference in the curriculum. Giving feedback is one of the efforts to support students' analytical thinking skills. Methods: The research used is Quasi-Experimental, with a Posttest-Only Control Design. The sampling technique used was Cluster Random Sampling. The research instrument was used through a test in the form of a description of 6 questions integrated into three indicators of analytical thinking ability (Differentiating, Attributing and Organizing). Results: showed that the average value of posttest analytical thinking ability in the experimental class was 63.67, which was greater than the control class, which was 56.63. Hypothesis testing through t-test at the 5% significance level obtained the value of tcount = 2.13 while ttable = 2.00, it is mean that tcount > ttable then H0 is rejected. Conclusions: The conclusion that can be formulated is that giving feedback has a significant effect on students' analytical thinking skills on the excretory system material, with the highest achievement indicator of analytical thinking ability achieved by indicators attributing.

The development of science and technology causes education to become a necessity for the younger generation. Based on the results of the survey, students analytical skills are still low, so an active learning strategy is needed that can improve students' analytical skills. Active learning strategies that can be used are Critical Incident strategies. This study aims to determine the effect of using Critical Incident learning strategies on students' analytical skills on the subject of environmental change. The research was carried out in class X MAN 9 Jakarta from March to June 2017. The research method used was quasi-experimental research design using posttest only control design. The population of this study were all students of class X MIA totaling 104 students. The data collection uses a multiple-choice test consisting of 24 items that are integrated with three types of indicators of analytical skills that are differentiating, organizing and attributing. The results showed that the average posttest value of the analytical skills of the experimental class was 64.88 while the control class was 62.49. Hypothesis testing through t-test at the significance level α = 5% obtained t count = 1.74 while t table = 1.67, because t count is greater than t table then H0 is rejected and H1 is accepted. Thus, it can be concluded that the use of Critical Incident learning strategies influences the analytical skills of class X MAN 9 Jakarta students.

Abstrak Motivasi merupakan dorongan yang mengakibatkan seseorang melakukan tindakan yang dapat berasal dari dalam diri (intrinsik) dan luar/lingkungan (ekstrinsik). Motivasi belajar dapat memengaruhi hasil belajar siswa, baik dari segi kognitif/pengetahuan, minat membaca, persepsi, dan Technological Pedagogical Content Knowledge. Penelitian bertujuan untuk mengukur effect size artikel penelitian tentang hubungan antara motivasi dan hasil belajar siswa IPA. Jenis penelitian yang digunakan adalah metaanalisis menggunakan instrumen lembar tabulasi data dan dianalisis menggunakan software openMEE. Artikel yang dipilih berjumlah 20 dengan rentang publikasi tahun 2016-2021. Rata-rata effect size yang diperoleh dari masing-masing artikel adalah tinggi (efek besar) sehingga diinterpretasikan bahwa terdapat korelasi yang signifikan antara variabel motivasi dan hasil belajar siswa  IPA. Hasil penelitian dapat memberikan acuan bagi guru bahwa motivasi sangat penting diberikan kepada siswa selama proses pembelajaran berlangsung. AbstractMotivation is an impulse that causes a person to take actions that can come from within (intrinsic) and outside/environmentally (extrinsic). Learning motivation can affect student learning outcomes, both in terms of cognitive/knowledge, reading interest, perception, and Technological Pedagogical Content Knowledge. This research aimed to measure the effect size of research articles on the relationship between motivation and learning outcomes of science students. The type of research used was meta-analysis using data tabulation sheet instruments and analyzed using openMEE software. The selected articles were 20 with a publication range of 2016-2021. The average effect size obtained from each article was high (large effect) so it is interpreted that there was a significant correlation between motivational variables and science student learning outcomes. The results of the research can provide a reference for teachers that motivation is very important given to students during the learning process.
