Abstrak— Telah dilakukan rancang bangun alat peraga fisika pada kasus gerak jatuh bebas berbasis Arduino. Alat peraga yang telah dikembangkan bertujuan untuk memvisualisasikan fenomena gerak jatuh bebas dan mengukur percepatan gravitasi bumi dan membuktikan konsep-onsep gerak jatuh bebas. Rancang bangun alat peraga menggunakan komponen elektronik seperti Arduino, sensor inframerah, sensor ultrasonik, push button, LCD, relay, dan LED sebagai komponen utama perangkat keras (hardware). Perangkat lunak (software) yang digunakan dalam mengembangkan alat peraga ini memanfaatkan compiler IDE Arduino berbasis bahasa C#. Besaran fisis yang diukur menggunakan alat peraga yang dikembangkan dalam penelitian ini adalah ketinggian benda dan waktu tempuh benda.

Theoretical Side

We propose a method by which one could use modified antimatter gravity experiments in order to perform a high-precision test of antimatter charge neutrality. The proposal is based on the application of a strong, external, vertically oriented electric field during an antimatter free-fall gravity experiment in the gravitational field of the Earth. The proposed experimental setup has the potential to drastically improve the limits on the charge-asymmetry parameter ϵ¯q of antimatter. On the theoretical side, we analyze possibilities to describe a putative charge-asymmetry of matter and antimatter, proportional to the parameters ϵq and ϵ¯q, by Lagrangian methods. We found that such an asymmetry could be described by four-dimensional Lorentz-invariant operators that break CPT without destroying the locality of the field theory. The mechanism involves an interaction Lagrangian with field operators decomposed into particle or antiparticle field contributions. Our Lagrangian is otherwise Lorentz, as well as PT invariant. Constraints to be derived on the parameter ϵ¯q do not depend on the assumed theoretical model.

Test Result

Background and purpose: Adolescence is a period of transition from childhood to adulthood. The problems facing adolescents are often related to reproductive health, one of which is fluorine albus. Many teenagers do not care about the fluoride of albus despite the enormous impact on women's reproductive health. One reason is the lack of knowledge about fluorine albus. Based on KISARA data there are 90.91% of girls in Denpasar City do not know the cause of fluorine albus. The purpose of this study was to determine differences in knowledge of young women before and after being given counseling about fluor albus. Method: The research design used was pre-experimental with one group pretest posttest design using 70 respondents taken by stratified random sampling. The results showed that the average score of adolescent girls' knowledge about fluor albus before being given counseling was 11.56 and after counseling was 14.23. There was an average increase in knowledge of 2.67. Results: Statistical test result using wilcoxon test get value p = 0.000 so that hypothesis accepted. Conculusion: It can be concluded that there is difference of adolescent knowledge about fluorine albus before and after given counseling.

A proposal is made to test Newton's inverse-square law using the perihelion shift of test masses (planets) in free fall within a spacecraft located at the Earth–Sun L2 point. Such an artificial planetary system in space (APSIS) will operate in a drag-free environment with controlled experimental conditions and minimal interference from terrestrial sources of contamination. We demonstrate that such a space experiment can probe the presence of a "hidden" fifth dimension on the scale of a micron, if the periapsis shift of a "planet" can be measured to sub-arc-second accuracy. Some suggestions for spacecraft design are made.

Penelitian ini bertujuan mengembangkan suplemen bahan ajar Bahasa Inggris membaca pemahaman yang kontekstual dan berkarakter sesuai model pembelajaran REACT yang memenuhi kelayakan bagi siswa kelas IX SMP. Metode penelitian menggunakan model pengembangan Borg and Gall (1989). Uji validasi dilaksanakan melalui uji ahli, uji perorangan, uji teman sejawat, dan uji kelompok kecil sedangkan uji efektifitas produk melalui pre-tes dan post-test. Data uji oleh ahli isi/desain dan media, perorangan, teman sejawat, dan tanggapan kelompok kecil dikumpulkan melalui angket, sedangkan hasil uji efektivitas penerapan dikumpulkan melalui test. Hasil-hasil uji dianalisis melalui statistik deskriptif kualitatif dan kuantitatif. Data hasil uji yang dikumpulkan melalui angket dianalisis menggunakan persentase dan hasilnya dikonversikan dengan tabel kualifikasi.

Product validation included experts validation, individual validation from the students, teachers validation, and classical validation, while the effectiveness of the product was done through the analysis of the pre-test and post-test. Data of evaluation were collected through questionaires distribution, and tests. The result of evaluation was analyzed through descriptive qualitative and quantitative technique. The data from questioners were analyzed in percentage, meanwhile, the data of the pre-test and post-test was analyzed using t-test. The t-test result was compared to the hypothesis. The result of validation form showed that the supplement was in a proper quality. The expert validation about the content and instructional design reached to 92% and media validation reached to 88%. They are categorized into nearly perfect and very good. In a line with this, the result of the t-test showed that there were a significant difference between pre-test and post-test result.
