Abstract

The effectiveness of learning is affected by the assistance stages (scaffolding) provided. For example, the scaffolding of type 2a and type 2b supports the causal-thinking approach in learning. The type 2a informs the causal model, number of causes and effect, while 2b informs its argument sample. This research aimed to identify the effect of causal thinking process (CTP) with scaffolding type 2a and 2b on optics problem-solving ability (PSA) of students. The type of the research was quasi-experiment with the non-equivalent-group design. Data were obtained with PSA-test and analyzed with the two-tail test with separated variance formula at significance degree of 5% to determine the effect of each type of the CTP on the PSA, also to determine its difference. The results showed that tcount for each of the first two t-tests were greater than ttable, but tcount for the third one was smaller than its ttable. This research concluded that the implementation of the CTP with the scaffolding of type-2a and 2b were effective to improve the student’s PSA. However, the improvements were not different.Efektivitas pembelajaran dipengaruhi bantuan tahapan (scaffolding) yang diberikan. Dengan pendekatan berpikir kausalitik ini, diperkenalkan scaffolding tipe-2a dan tipe-2b. Kedua scaffolding ini menginformasikan model kausal serta jumlah Cause dan Effect tetapi pada tipe-2b ditambah contoh argumentasinya. Penelitian ini bertujuan mengidentifikasi pengaruh proses-berpikir-kausalitik (PBK) ber-scaffolding tipe-2a dan tipe-2b terhadap kemampuan-pemecahan-masalah (KPM) optik siswa. Jenis penelitian kuasi-eksperimen dengan desain non-equivalent-group. Data diambil menggunakan alat tes-KPM dan dianalisis dengan uji-t dua pihak menggunakan rumus separated varians pada signifikansi 5% untuk mengetahui pengaruh PBK tipe-2a dan 2b terhadap KPM, serta perbedaan kedua pengaruh tersebut. Hasil menunjukkan nilai thitung untuk dua uji-t pertama lebih besar dari tTable terkait tetapi nilai thitung untuk uji ketiga adalah lebih kecil dari tTable-nya. Simpulan penelitian implementasi PBK ber-scaffolding tipe-2a dan 2b masing-masing berpengaruh terhadap peningkatan KPM siswa tetapi kedua pengaruh tersebut tidak berbeda.

In this study, aluminum foil was used as anode, polyetylene polyprophylene (PE/PP) as separator, electrolyte from AlCl3/[EMIm]Cl and graphite coated corncob, an activated charcoal, as cathode. Coating method of cathode materials was done by mixing both graphite and activated charcoal with varied composition 1:0.5, 1:1, 1:1.5, and 1:3. The coating process began by mixing the graphite and corncob with ethanol as a solvent for six hours, then heating in an oven at 80 °C for three days, gradual drying in a furnace at 350 °C for five hours and sintering at 600 °C for six hours. From this research, SEM results showed that carbon particles were evenly distributed, with spherical particles. The spherical shape was the main requirement of carbon formation in order to produce high energy. Based on the results, battery potential was 2.54 V with average of optimal capacity at a ratio of graphite and corncob activated charcoal 1:1.5 was 83.067 mAh/g. The highest efficiency was also at a ratio of 1:1.5 of 97.20%, because at this ratio, there was an increasing in percentage of element C 91.74%, greater than the percentage of element C on the other three cathode samples.Salah satu sistem penyimpan energi terbarukan yang bisa digunakan saat ini adalah baterai ion aluminium.

Abstract

This study presents the calculation results of the cell, and core Gas-cooled Fast Reactor (GFR) based fuel Uranium-Plutonium Nitride (U, Pu)N. Parameter survey results of calculations of the fuel cell consisting of a kinf, burnup level, and the conversion ratio and for the calculation of the reactor core produce value keff during a refueling cycle. The calculation was performed by using a set of SRAC program by comparing three types of fuel cell designs. Reactor Design A based on natural uranium could not reach criticality because of keff < 1. Design B used the enrichment of uranium-235 by 9.5% to reach a critical condition at keff > 1. The critical state was also achieved by Design C utilizing natural uranium, and plutonium 5.5% result value keff = 1.015 in the first year of burnup and continues to increase 1.083 in the tenth year without refueling. Moreover, plutonium can replace the uranium enrichment process.Penelitian ini menyajikan hasil perhitungan sel dan teras gas-cooled fast reactor (GFR) berbasis bahan bakar Uranium- Plutonium Nitride (U,Pu)N. Parameter Survey untuk hasil perhitungan sel bahan bakar terdiri dari kinf, level burnup, dan conversion ratio. Sedangkan pada perhitungan teras reaktor dihasilkan nilai keff untuk satu siklus pengisian bahan bakar. Perhitungan dilakukan dengan menggunakan seperangkat program SRAC dengan membandingkan tiga jenis desain sel bahan bakar yang berbeda. Reaktor Desain A berbasis uranium alam tidak mencapai kekritisan karena keff < 1. Desain B menggunakan pengayaan uranium-235 sebesar 9,5% mencapai kondisi kritis pada keff > 1. Keadaan kritis juga dicapai oleh Desain C yang memanfaatkan uranium alam dan plutonium 5,5% menghasilkan nilai keff = 1,015 di tahun pertama burnup dan terus meningkat hingga 1,083 pada tahun kesepuluh tanpa pengisian ulang bahan bakar. Pemanfaatan plutonium sebagai bahan bakar dapat menggantikan proses pengayaan pada uranium.

Abstract

The research aims to reveal the influence of the Problem Based Learning (PBL) model on students' critical thinking ability in optical instrument material. This research is a quasi-experimental research with Pre-test and Post-test Design. The subjects of this study were class X MAN 3 Malang. The experimental and control classes received PBL models and conventional learning models respectively. The instrument of this study was the Optical Instrument Critical Thinking Ability Test in the form of 14 essay questions with Cronbach’s alpha reliability 0.78. The research data were analyzed using several tests including t-test, N-gain, and size effect tests. Based on the results of the analysis, it was shown that the implementation of the PBL model succeeded in increasing students' critical thinking ability higher than that of conventional learning. The experimental class was able to reach the high N-gain score category, while the control class was in the medium category. The research has a “large” size effect category. This means that the PBL model implemented has a stronger influence than that of conventional learning in improving students' critical thinking ability. Thus, the PBL model can be recommended as an alternative learning model in improving students' critical thinking ability in physics learning on the topic of optical instruments.Penelitian bertujuan untuk mengungkap pengaruh model Problem Based Learning (PBL) terhadap kemampuan berpikir kritis siswa pada materi alat optik.

Abstract

There is the fact that the students' learning outcome in Applied Physics course related to the application of the mining industry is unsatisfactory. Based on the results of the final score, the rate of successful students was only around 40%. Moreover, students' understanding application is also not by the desired competencies. In this research, a learning model was developed from the Contextual Teaching and Learning Model (CTL), i.e., DILA model which consists of four syntaxes (Display, Inquiry, Learning Community, and Authentic Assessment). The effectiveness of the DILA learning model was investigated to improve students’ learning outcomes in the Applied Physics course. This research employed the quasi-experimental design where the experimental class was treated by DILA model based on Contextual Teaching and Learning; whereas control class was not treated by the model. Data were obtained from the results of the pre-test and post-test scores; then it was analyzed by a parametric with an independent t-test, related t-test, and the effect size. The results indicate that there was a significant increase in students’ learning outcomes in the experimental class compared to the control class. In conclusion, DILA model can improve students’ learning outcomes in the Applied Physics course effectively.Hasil belajar Fisika Terapan yang diperoleh mahasiswa yang terlihat dari nilai akhir semester dan penerapan pada industri pertambangan pada umumnya tidak memuaskan.

Abstract

In this work we explain a strange quantum phenomenon in biology that the European Robin uses to navigate. The bird’s brain contains a chemical called cryptochromes which has two of its electrons entangled through collision with photons. These two electrons hop between singlet and triplet states. This hopping is sensitive to the earth’s magnetic field causing different signals to be transferred to its brain. It is believed that these birds use quantum entanglement for their navigations. We also discuss the importance of this phenomenon in trying to find the origin of life. We also explain the view of some who believe that quantum field is well entrenched in the origin of life and that we have to look for a quantum self-replicator that can repeat itself.Hasil penelitian ini mencoba menjelaskan fenomena kuantum yang aneh pada ranah biologi dimana burung robin eropa bernavigasi menggunakannya. Otak burung tersebut mengandung material kimia yang disebut dengan cryptochromes yang mempunyai dua buah elektron yang terjebak dalam pengaruh interaksi tumbukan antara elektron tersebut dengan foton. Dua elektron tersebut melompat di antara keadaan singlet dan triplet. Lompatan ini dipengaruhi oleh medan magnetik bumi yang memberikan sinyal berbeda-beda untuk ditransfer ke otaknya. Burung-burung ini diyakini menggunakan prinsip pengaruh kuantum untuk navigasinya. Kami juga mengungkap pentingnya fenomena ini dalam usaha mencari asal mula kehidupan. Kami juga menjelaskan sudut pandang yang mempercayai bahwa medan kuantum diyakini berperan penting dalam penjelasan tentang asal mula kehidupan dan bahwa kita harus mencari tahu tentang pembelahan materi dengan pengaruh kuantum yang dapat berlangsung berulang-ulang dengan sendirinya.
