Abstract

Pembelajaran IPA di tingkat SMP kini diharapkan dilaksanakan secara terpadu agar siswa memperoleh pemahaman secara holistik. Sementara itu di lapangan, pembelajaran IPA belum diajarkan secara terpadu. Tidak jarang juga bahan ajar yang digunakan oleh guru-guru SMP belum menyajikan IPA secara terpadu. Bahan ajar dari kajian fisika, kimia dan biologi yang disajikan secara terpisah. Bahan ajar memberikan ruang kepada siswa untuk belajar kapan saja dan dimana saja. Pembelajaran diharapkan dapat mengakomodir kesiapan, minat, serta profil siswa demi terwujudnya merdeka belajar. Pembelajaran berdiferensiasi merupakan strategi pembelajaran yang mampu mengakomodir kebutuhan siswa untuk mewujudkan merdeka belajar. Tujuan dari penelitian R & D ini adalah untuk menghasilkan bahan ajar berupa modul IPA Terpadu tipe connected berbasis pembelajaran berdiferensiasi pada materi lapisan Bumi kelas VII. Hasil yang diperoleh setelah dilakukan pengujian terhadap bahan ajar yang dikembangkan kepada ahli materi, ahli media dan uji praktisi (guru dan siswa) menunjukkan kategori baik pada rentang nilai 75%-89%.

Abstract

Hydrogenated amorphous silicon (a-Si:H) solar cells with δ-doped p-layer have been fabricated using double chamber Plasma Enhanced Chemical Vapor Deposition (PECVD). 10 % Silane (SiH4), diborane (B2H6) and phosphine (PH3) gases in hydrogen (H2) gas were used as gas sources. δ-Doped p-layer was deposited by using very thin boron layer as dopant source. Current (I) - voltage (V) characteristic measurement was done using xenon lamp as light source with power of 250 watts and voltage of 24 volts. The result shows that the efficiency of δ-doped p-i-n a-Si:H solar cell without annealing decreases from 5.39 % to 3.49 % as the illumination time increases from 0 hours to 2.5 hours. The stable efficiency obtained is3.6 %. It means that there is an efficiency drop of 33.15 %. Solar cell efficiency annealed at temperature of 150OC decreases from 8.59 % to 6.69 % as the illumination time increases from 0 hours to 2.5 hours. Its stable efficiency obtained is 7.11 %. It means that there is an efficiency drop of 17.23 %. Thus the annealing process decreases the efficiency drop.

Abstract

Simulations have been carried out to study the recrystallization of iron materials after heat treatment. The heat treatment carried out consists of heating the iron from room tempera-ture to critical temperature with different heating temperatures and cooling to room tem-perature with different cooling times. This study was carried out to obtain information on the occurrence of material recrystallization after the heat treatment process was carried out. This simulation approach was carried out using molecular dynamics methods and utilizing LAMMPS software. The heat treatment process begins by heating the iron from room temperature (300 K) until it reaches a critical temperature, even past the critical temperature value. Then a cooling process is carried out to observe the material recrystallization process. Through these two stages of heat treatment, analysis is carried out to observe the material structure at the end of the simulation. Based on the simulations that have been carried out, the results show that the ma-terial’s recrystallization is more influenced by the cooling time than the initial cooling tem-perature. More than 60% of the BCC structures formed at the end of the simulation for all initial cooling temperatures, but for very short cooling times 16% of the BCC.

Abstract

The high-energy milling (HEM) synthesis method has produced activated carbon powder from rubber ore shell waste. The activated carbon was prepared using a chemical method with activation temperatures varying between 400, 500, and 600°C. Temperature optimization resulted in activated carbon with a maximum carbon content at 600°C. The activated carbon was then milled for various times: 0, 30, 60, and 90 minutes. The crystallinity and surface morphology of the samples were then confirmed using an X-ray diffractometer (XRD) and scanning electron microscope (SEM) characterization. Based on the XRD graph, the percentage of structural regularity, or degree of crystallinity, of the activated carbon tended to decrease from 18.17% without milling treatment to 17.52% at 30 minutes of milling, 17.45% at 60 minutes of milling, and 17.35% at 90 minutes of milling. SEM images also show a decrease in the average pore diameter from approximately 0.45 µm to 0.20 µm with a more homogeneous intraparticle morphology structure when the milling time is increased from 30 minutes to 90 minutes. This study demonstrates the potential of rubber seed shell waste for processing into activated carbon. The HEM method can significantly reduce the grain size of activated carbon and increase its surface area and reactivity, making it more effective in applications as an adsorbent and filter.

Abstract

The rapid transformation of science education in the digital era calls for pedagogical innovations that promote deep conceptual understanding rather than rote memorization. This study aims to investigate the effect of integrating PhET interactive simulations into a guided inquiry learning model on students’ conceptual understanding of elasticity and Hooke’s Law. A quasi-experimental pretest–posttest control group design was employed with 55 eleventh-grade science students at SMA Frater Don Bosco Lewoleba, Indonesia. The experimental group experienced PhET-supported guided inquiry, while the control group received guided inquiry instruction with real demonstration tools. Statistical analysis revealed that students in the experimental group achieved significantly higher posttest scores than those in the control group (t(53) = 2.89, p = 0.01), with a medium-to-high effect size (Cohen’s d = 0.67). The findings suggest that PhET interactive simulations function as cognitive scaffolds by visualizing abstract physical phenomena, reducing extraneous cognitive load, and supporting conceptual reconstruction during inquiry activities. These results highlight the pedagogical value of embedding digital simulations within inquiry-based physics instruction to enhance students’ conceptual understanding and foster meaningful learning in abstract scientific domains.
