Abstract

Use of magnets vary in life. Use of magnets depending on needs. Magnets can be used from the side: the field is generated, attractive force and repel force between the two magnets. Special utilizing repel forces magnetic one used on the railways to reduce the friction between wheel and rail.One way to determine the amount of repel force magnet is to use the object equilibrium. Two similar magnetic poles will repel. Large repulsion force depends on magnetic field (B) accrued and distance (r) the two magnets. Two magnets with similar poles are placed in the shell will give rise to vertical distance between the magnets to each other.  There is a balance between the repulsive magnetic force with the gravity due to the mass of the magnet when the magnet above the rest. Magnetic repulsive force can be determined for certain r by changing the magnetic mass. Large magnetic gravity on each r can be computed from the gravity due to the magnetic mass.   Keywords: repel force, gravity

Abstract

Penelitian ini bertujuan untuk mengetahui perbedaan pola agregasi eritrosit antara subjek normal dan subjek penderita kanker payudara menggunakan Principal Component Analysis (PCA) serta untuk mengetahui deskripsi proses terjadinya agregasi eritrosit ditinjau dari parameter muatan listrik Potensial Zeta. Ethylenediaminetetraacetic Acid (EDTA) digunakan untuk mencegah pembekuan darah. Sampel darah Vena yang sudah dimasukkan EDTA dilakukan pengambilan data uji  spektrofotometri. Setelah diperoleh data absorbansi selanjutnya nilai absorbansi dengan interval 7 detik diolah menggunakan aplikasi Matlab dan Microsoft Excel. Parameter pembeda pola agregasi eritrosit kedua kelompok dianalisis menggunakan model pendekatan PCA grafik klusterisasi 2 dimensi dan 3 dimensi. Hasil penelitian diperoleh tidak ada perbedaan pola agregasi eritrosit antara subjek penderita kanker payudara dan subjek normal apabila diolah menggunakan metode PCA. Grafik 2 dimensi menunjukkan posisi kedua kelompok saling bertumpang tindih, tidak dapat membedakan subjek kelompok kanker payudara dan subjek normal. Hal ini didukung dengan persen variansi data untuk PC1 sebesar 23,32% dan PC2 sebesar 18,02% dengan persen variansi kumulatif 41,34%. Grafik 3 dimensi menunjukkan hal yang serupa, kedua kelompok saling bertumpang tindih dengan persen variansi data PC3 sebesar 12,86% dan persen variansi kumulatif sebesar 54,2%. Kesimpulan, metode PCA tanpa langkah pra-pemrosesan data tidak dapat membedakan pola absorbansi agregasi eritrosit antara subjek kanker payudara dan subjek normal.Kata Kunci: absorbansi, EDTA, eritrosit, kanker payudara, PCA

Abstract

Tujuan dilakukannya penelitian ini adalah pertama, mengetahui perbedaan pola interaksi eritrosit dalam darah-EDTA antara penderita tumor payudara dan subjek normal ditinjau dari hukum Coulomb. Kedua, mengeteahui ada tidaknya perbedaan pola absorbansi eritrosit berdasarkan hasil analisis parameter deterministik dan stokastik. Penelitian dilaksanakan pada bulan Juni-November 2021. Lokasi penelitian berada di gedung Radioputro dan gedung PAU Pascasarjana UGM. Pola Absorbansi Eritrosit dalam darah-EDTA dideteksi menggunakan spektrofotometer UV-Vis dengan panjang gelombang (λ) 560nm. Subjek penelitian yang digunakan adalah33 subjek normal dan 32 subjek tumor payudara. Sampel darah sebanyak 3 ml diambil dari lengan bawah subjek penelitian. Sampel darah ini digunakan untuk uji pola absorbansi sebanya 550 μL, dan sisanya untuk pengujian darah rutin dan metode Westergren. Hasil data dari uji spektrofotometer berupa nilai absorbansi terhadap waktu. Nilai absorbansi dianalisis menggunakan google colab dengan bahasa pemrograman python. Uji beda parameter deterministic dan stokastik pola absorbansi eritrosit kedua kelompok penelitian menggunakan Mann-Whitney. Pola absorbansi eritrosit dalam darah-EDTA yang tidak menentu pada kedua kelompok menyebabkan data sulit dianalisis berdasarkan hukum Coulomb. Analaisis uji beda parameter deterministik (d) dan stokastik (s) dari kedua kelompok diperoleh signifikansi uji beda 𝑑1, 𝑑2, 𝑑3, 𝑠1, 𝑠2, dan 𝑠3 adalah sebesar 2.67 × 10−7, 1.68 × 10−5, 6.22 × 10−5, 0.181, 3.94 × 10−7 dan 9.95 × 10−8. Berdasarkan hasil uji beda tersebut, hanya ada satu parameter yang tidak berbeda signifikan  yaitu d3 (P 0.05).

Abstract

The research in this article aims to review the available literature on integrating ethnoastronomy-based NASE on the understanding and trust of teachers, students, and society. The method used in this study is a literature review from 2010-2022, which strictly discusses the challenges in learning astronomy and astronomy in local wisdom with two questions that need to be answered, namely (1) what kind of challenges are faced when conducting astronomy learning and does NASE influence astronomy learning? (2) Does local wisdom relate to astronomical learning, and how does the community's understanding and beliefs relate to Ethnoastronomy? The results of the literature review stated that NASE has a positive influence on the challenges of learning astronomy, NASE has a relationship with local wisdom that discusses astronomy, and this research also shows that the relationship between local wisdom and astronomy with NASE can increase people's understanding and trust in Ethnoastronomy from each culture they have. This article recommends that astronomy-based NASE integrated learning with local wisdom can be applied in various countries, especially astronomy learning in Indonesia, so that the culture owned is preserved due to the times and can be used for learning.

Abstract

One of the important skills that must be mastered in 21st-century learning is communication skills. The facts show that students' communication skills in learning physics, specifically on the topic of global warming, are still low. This research aims to determine the feasibility and effectiveness of the global warming e-book based on problem-based learning (PBL) assisted by PhET interactive simulation to improve students' communication skills. The type of research used is pre-experimental, with a one-group pretest-posttest research design. The sampling technique is cluster random sampling, the modeling class and the implementation class are randomly selected. This research was conducted on 55 students in class X of high school, consisting of 32 students in the modeling class and 23 students in the implementation class. Data collection techniques are carried out through validation and pretest-posttest. The validation data to determine the feasibility of e-books and communication ability test instruments were analyzed using the V 'Aiken equation. The effectiveness was analyzed using the N-Gain test and to determine the significance of the increase using the ANOVA test with eta squared (effect size) analyzed with the SPSS program. The results of the study show that the validity of the e-book is on very good criteria, so it is worth using. The results of the N-Gain test of the modeling class and the implementation class showed that the use of e-books was quite effective in improving students' communication skills, with an impact size of 0.406 in the modeling class and 0.519 in the implementation class. So, this global warming e-book can be used by physics teachers in physics learning. The limitations of this study include the use of subjects limited to only two classes and restricted time allocation. Therefore, future research is expected to conduct studies on a larger scale and consider time allocation when selecting the learning model.

Abstract

The paper discusses the possible ways' of improving the quality of education in Indonesia in the future. It starts with the background describing die reality of the education nowadays and the need of making changing in any aspect of education.To yield better products of education, there must be improvements in the process of education, in which each components of education system should interact one another. Besides, the purpose of education should be clear and inclusive which does not only concern in the cognitive side but also in affective and psychomotor sides. After setting the purpose of education there must be a change in education paradigm as well. We have to see that education is a means to make students mature in their life. To generate change, innovations must be made by any parties of education process. Especially teachers should always innovate their teaching method so that the result of their teaching process will be maximum. Last but not least, education should ensure the output and the outcome. When the aspects above mentioned are well carried out, education will not only yield better output, which has good grades or marks, but it will also yield better outcome which will not find difficulties in getting the first job.
