Abstract

Penelitian ini bertujuan untuk mengidentifikasi dan menganalisis upaya peningkatan perkembangan akhlak dan moral anak usia dini melalui kegiatan Shalat Dhuha di TK Ar Raihan. Pendidikan akhlak dan moral pada anak usia dini sangat penting untuk membentuk karakter yang baik, terutama di tengah tantangan globalisasi yang kian meluas ini. Kegiatan Shalat Dhuha yang dilaksanakan secara rutin diharapkan dapat memberikan pengaruh positif terhadap pembentukan sikap dan perilaku anak. Metode yang digunakan dalam penelitian ini adalah pendekatan kualitatif dengan observasi, wawancara, dan analisis dokumen. Hasil penelitian menunjukkan bahwa kegiatan Shalat Dhuha tidak hanya meningkatkan aspek spiritual anak, tetapi juga berkontribusi pada perkembangan sosial, emosional, dan moral mereka. Dengan demikian, kegiatan Shalat Dhuha ini dapat dijadikan salah satu strategi efektif dalam Pendidikan karakter anak usia dini.

Abstract

This research was conducted to assess the growth of students' scientific literacy skills using the Guided Inquiry learning model assisted by PhET Simulation on Wave material. The method used in this research is Penelitian Tindakan Kelas (PTK) or Action Research with the research subjects were 39 students of SMA Negeri 6 Kabupaten Tangerang class XI MIPA 3. This research design consists of three cycles with each cycle consisting of four stages: planning (plan), implementation (action), observation (observe), and reflection (reflect). The results of the research show that the application of the Guided Inquiry learning model assisted by PhET Simulation can improve students' scientific literacy abilities with the average percentage value of scientific literacy abilities in the "good" category, this can be seen in the greatest increase that occurred in cycle III, which was found The average percentage increase in the science content indicator was 68.7%, the science context indicator was 63.7%, and the science process indicator was 65.5%. From the results of observations from this research, it can be seen that through the Guided Inquiry learning model assisted by PhET Simulation, students are more active in the learning process.

Abstract

This research shows that using guided inquiry with PhET simulations significantly improves students' critical thinking skills. In this study, Classroom Action Research (Penelitian Tndakan Kelas) method was used with the participation of 39 students of Class XI IPA 3 SMAN 6 Tangerang Regency. Data collection spanned three learning cycles comprising planning, action implementation, observation, and reflection. outcomes consistently showed progress across cycles, with the average score on critical thinking tests rising from 65 pre-intervention to 80 by the third cycle. Moreover, the percentage of students achieving a "Very Good" rating increased significantly from 10% to 20% in cycle III. Observations highlighted heightened student engagement and underscored the pivotal roles of teacher and peer feedback in advancing critical thinking skills. Consequently, the guided inquiry method complemented by PhET simulations effectively cultivated a vibrant and efficacious learning atmosphere that fostered students' critical thinking capabilities.

Abstract

A study has been carried out on supercapacitor electrodes as an electrical energy storage media based on pepper shell activated carbon. The Synthesis is done by mixing the waste carbon pepper shell with an activator HCl with a ratio of 1 : 4. Furthermore, the activated carbon is activated physically by using a pyrolysis temperature of 600 0C. The SEM results indicate that carbon has a porous morphology with a pore size of 24.6 nm which is a mesoporous category. Electrochemical properties are analyzed using cyclic voltammetry (CV). The CV results at the scan rate of 1 mV/s indicate the specific capacitance value generated is 0.45 Fg-1. The results showed that pepper shell waste has the potential to be used as a supercapacitor electrode material

Abstract

This study was conducted to examine the role of Islamic education in shaping the spiritual intelligence of children with disabilities at SLB IT Sahabat Al-Qur'an Binjai. Qualitative methods with a case study approach have been used in this study. Data have been collected through direct observation, in-depth interviews, and documentation. Various religious activities such as congregational prayer, memorizing prayers, learning the stories of the prophets, and practicing morals in everyday life have been consistently implemented and have been proven to contribute to strengthening the spiritual aspects of children. Learning to memorize the Qur'an has also been used as a means of developing self-confidence and emotional stability of children with disabilities. Support from teachers, parents, and the social environment has been identified as a major factor in the success of this process. Thus, an inclusive and adaptive Islamic education approach is highly recommended to be further developed in order to shape the spiritual quotient of children with special needs.

Abstract

Glass bottle waste is inorganic waste that cannot be broken down by microorganisms. The high SiO2 content in glass bottle waste has the potential as a base material in the synthesis of silica gel. This study aims to determine the characteristics and ability of silica gel as adsorption of Pb metal ions in water under Bangka. The stages in this study were started from the extraction of silica from waste glass bottles, synthesis of silica gel, activation with HCl and testing the adsorption of Pb metal ions in under water. The results showed that the characteristics of silica gel with variations of 100 and 200 mesh, the concentration of 3M NaOH, 3M HCl using SEM EDS had an amorphous structure and the SiO2 content graph had high peaks. In the BET test, the pore radius was 1164.207 for the 100 mesh sample and 1293.102 for the 200 mesh sample. The AAS results showed that in the treatment of 100 mesh, the Pb value decreased by -0.1122, while for 200 mesh also decreased by -0.1322. The Pb value is minus because the tool can only read with a standard limit of 0.1. If it is less than 0.1, then the tool cannot read the value on Pb metal even though the value is minus but has a value. The greater the minus, the lower the Pb value. So silica from glass bottle waste can adsorb heavy metals (Pb) on the surface water underneath

Abstract

Pemenuhan kebutuhan energi dibutuhkan suatu piranti penyimpan yang memiliki kapasitansi spresifik yang tinggi yaitu superkapasitor. Superkapasitor adalah perangkat penyimpan muatan yang memiliki kapasitansi spesifik yang tinggi. Dalam penelitian ini telah dilakukan preparasi dan karakterisasi karbon aktif dari limbah kulit lada sebagai bahan elektroda superkapasitor. Karbon diaktivasi dengan variasi aktivator NaOH 1 M, 3 M dan 5 M dilanjutkan dengan pemanasan pada suhu 700˚ C selama 3 jam dengan dialiri gas nitrogen (N2). Karbon selanjutnya dikarakterisasi menggunakan Scanning Electron Miscroscopy-Energy Dispersive Spektroscopy (SEM-EDS), Brunauer-Emmett-Teller (BET) dan pengukuran kapasitansi menggunakan metode Cyclic Voltametry (CV). Hasil pengujian menunjukkan karbon aktif limbah kulit lada berpori dengan bentuk pori bulat pada sampel 3 M dan 5 M, sedangkan pada 1 M terdapat pori berongga yang pipih dan panjang. Hasil EDS setiap sampel memiliki kandungan unsur karbon (C) secara berurut yaitu 77,57%, 75,96%, dan 74,62%. Hasil BET menunjukkan luas permukaan maksimum sebesar 149,319 m2/g. Kapasitansi elektroda superkapastitor tertinggi diperoleh pada konsentrasi 5 M dengan laju scan 1 mV/s yaitu 12,68 F/g.
