Abstract

Abstrak Fosfor BCNO yang terdispersi pada likuid telah berhasil disintesis menggunakan metode hidrotermal. Bahan dasar (prekursor) yang digunakan adalah asam borat [B(OH)3] sebagai sumber boron, urea [(NH2)2CO] sebagai sumber nitrogen, dan asam sitrat (C6H8O7)sebagai sumber karbon. Dalam penelitian ini, telah dilakukan variasi rasio molar nitrogen terhadap boron (N/B) dan rasio molar karbon terhadap boron (C/B) dan pengaruhnya terhadap pendaran fosfor BCNO yang dihasilkan. Hasil karakterisasi spektrum fotoluminesen dari sampel yang dibuat menunjukkan bahwa pendaran fosfor BCNO mempunyai puncak emisi tunggal disekitar warna biru (~450 nm) ketika dieksitasi dengan sinar UV(365 nm). Intensitas pendaran dipengaruhi oleh kadar karbon terhadap kandungan boron (C/B) dan kadar nitrogen terhadap kandungan boron (N/B). Penambahan kadar karbon dan nitrogen diketahui dapat meningkatkan intensitas pendaran. Sedangkan intensitas optimum pendaran fosfor BCNO dicapai pada saat ratio molar C/B = 1 dan N/B =20. Kata kunci: Fosfor BCNO, Spektrum fotoluminesen, Metode hidrotermal. Influence of Precursor Molar Ratio on the BCNO Photoluminescence synthesized by Hydrothermal Method Abstract BCNO phosphor which is dispersed into liquid has been successfully synthesized by using hydrothermal method. The precursor consists of the borate acid [B(OH)3] as boron source, urea [(NH2)2CO] as nitrogen source, and citric acid (C6H8O7) as carbon source. In this research, molar ratio variations of nitrogen and carbon  towards boron (N/B and C/B), and their influence on resulted BCNO phosphor luminescence were done. The characterization results of the sample shows the single peak of BCNO phorphorous luminescence around blue color (~450 nm) on the photoluminescence spectrum, when excited by UV light (365nm). The photoluminescence intensity was affected by the ratio N/B and C/B. The increase of carbon and nitrogen ratio can increase the photoluminescence intensity. The optimum intensity of BCNO phosphor photoluminescence was obtained at the molar ratio N/B = 20 and C/B =1. Keywords : BCNO phosphor, Photoluminescence spectrum, Hydrothermal method.

Abstract

Mata kuliah Fisika Dasar memiliki peran penting, khususnya bagi mahasiswa calon guru Madrasah Aliyah di Program Studi Pendidikan Fisika. Namun, pada perkuliahan yang penting ini masih terdapat mahasiswa yang kesulitan pemahaman karena tidak tahu konsep maupun miskonsepsi. Untuk mengetahui hal tersebut, kami menggunakan teknik CRI (Certainty Response Index) yang dimodifikasi untuk menganalisis kesulitan pemahaman konsep mahasiswa calon guru Fisika. Metode yang digunakan dalam penelitian ini adalah metode deskriptif kuantitatif dengan desain yang dipilih adalah one shoot case study. Deskripsi dan interpretasi statistik digunakan untuk analisis data. Sampel yang dipilih, yaitu seluruh mahasiswa calon guru di Program Studi Pendidikan Fisika semester 1 tahun ajaran 2015/2016 yang berjumlah 90 orang. Berdasarkan teknik CRI yang dimodifikasi pada materi elastisitas dan gerak harmonik sederhana didapatkan kelompok tidak tahu konsep (36,8%) dan miskonsepsi (32,2%) selanjutnya tahu konsep (28,6%) dan sebagian kecil (2,5%) tahu konsep tetapi kurang yakin.

Abstract

Free fall motion in air medium is only influenced by gravitation acceleration. However, there are several variables that caused the observations to be different with the concept. Variables, such as air drag and terminal velocity, are often teachers not presented in detail, causing misconceptions. This study aims to develop a simple experiment on free fall motion by identifying air drag and terminal velocity. The data in this study is the video of free fall motion of paper and scraper analyzed using Tracker video analyze. From the video analyzed, information is obtained in the form of time (t), track (l, θ), and velocity (v) of the object. This study shows that the air drag force increase unto the terminal velocity. The calculation of the drag coefficient giving the number of the paper 2,16 and the scraper 2,10. According to data analyzed, the air drag force is affected by the mass (m), area (A), and the air drag force (FD) with the linear correlation until it reaches the terminal velocity. The result of this study may use as references of free fall motion experiment with other objects and analyze.

Abstract

Abstract The program of USAID PRIORITAS has a follow-up activity in form of accompaniment program. The accompaniment is committed to ensure that the teachers apply the training results. One of the accompaniments is carried out at MI Al Misbah Cipadung Bandung to apply module 3 related to skills of science. Focus of the accompaniment is to observe the feasibility of accompaniment activities, examine students’ skills in doing an experiment and making an experimental report. Data are acquired through observation and assessment rubric. The results of observation show that the teachers carry out six observed aspects, (setting of students’ seats, teachers’ role as facilitator, serving individual difference, paying attention to gender, the learning using the scientific approach, and students’ works), while the aspect of assessment of authenticity and literacy is not carried out. The average of students’ skills in carrying out and writing down the experiment belongs to good category.Abstrak Program USAID PRIORITAS memiliki aktifitas tindak lanjut berhubungan dengan pendampingan guru.

Abstract

Pengabdian ini bertujuan untuk menganalisis tingkat pemahaman dan kesiapan guru dalam mengimplementasikan Projek Penguatan Profil Pelajar Pancasila-Rahmatan Lil Alamin (P5RA), mengidentifikasi kendala yang dihadapi guru dalam melaksanakan P5RA, dan meningkatkan kompetensi guru dalam mengimplementasikan P5RA di madrasah. Pengabdian ini menggunakan metode service learning dengan lima tahapan, yaitu identifikasi kebutuhan, perencanaan kegiatan, implementasi, refleksi, dan tindak lanjut. Hasil identifikasi kebutuhan menunjukkan ada 47% guru yang belum memahami Kurikulum Merdeka, dan 22% guru yang belum siap mengimplementasikan Kurikulum Merdeka di madrasah, dengan 59% guru menyatakan kurangnya pelatihan sebagai alasan. Pengabdian dilaksanakan di empat Kabupaten di Jawa Barat meliputi Kab. Subang, Kab. Sumedang, Kab. Tasikmalaya dan Kab. Garut dengan jumlah peserta 155 guru madrasah. Hasil tes pengetahuan guru sebelum dan sesudah pelatihan menunjukkan ada peningkatan yang signifikan. Hasil refleksi bersama menunjukkan bahwa guru makin siap dalam melaksanakan P5RA di madrasah. Tindak lanjut dari pengabdian ini adalah proses bimbingan dan konsultasi intensif di tiap sekolah secara berkelanjutan.

Abstract

This study offers a comprehensive approach that has not been widely explored, integrating PhET interactive simulations and the Phyphox sensor application to analyze the simultaneous influence of four physical parameters amplitude, frequency, dispersion angle, and pressure on the characteristics of sound waves. The integration of PhET interactive simulations and the Phyphox application enables real-time visualization and experimental data measurement through smartphone sensors. Furthermore, this research contributes new insights by exploring the dispersion angle in the context of wave direction and intensity, a topic rarely discussed in digital media-based acoustic studies. The method used is a quantitative experiment with amplitude variations from 1 to 10 and frequencies of 400 Hz, 500 Hz, and 600 Hz, measured at distances of 1 cm, 3.25 cm, and 5.5 cm. The study also includes observations of reflection and interference patterns of waves at propagation angles of 18°, 45°, and 90°, as well as an analysis of the effect of air pressure on sound intensity, with pressure varied from 0.0 atm to 1.0 atm. The results show that sound wave intensity increases with higher amplitude and frequency, in accordance with the theory that intensity is proportional to the square of the amplitude. The propagation angle influences the reflection and interference patterns, resulting in varied energy distribution. Additionally, air pressure significantly affects sound intensity, emphasizing the crucial role of the medium in sound wave propagation.
