Abstract

Penelitian ini bertujuan untuk mendeskripsikan pengaruh model pembelajaran konsep dengan mengintegrasikan teknik skimming terhadap prestasi belajar siswa pada sub materi pokok perpindahan kalor. Pada penelitian ini, skimming yang merupakan teknik membaca cepat berperan dalam meningkatkan kesiapan siswa untuk belajar sehingga siswa dapat berperan aktif dalam pembelajaran dan dengan pembelajaran konsep siswa dapat mengeluarkan pendapat mengenai konsep yang telah mereka temukan dalam kehidupan sehari-hari (contoh dan non contohnya) sehingga siswa lebih mudah untuk menerima dan memahami konsep yang diajarkan serta bersikap lebih kritis. Populasi penelitian adalah siswa kelas X SMAN 18 Surabaya dan rancangan penelitian yang digunakan adalah true experiment design. Berdasarkan analisis aspek kognitif siswa menggunakan uji-t dua pihak dan uji-t satu pihak diperoleh hasil bahwa prestasi belajar siswa di kelas eksperimen lebih baik dibandingkan dengan prestasi belajar siswa di kelas kontrol. Hasil analisis juga menunjukkan bahwa pembelajaran konsep dengan mengintegrasikan teknik skimming yang diterapkan pada penelitian ini berjalan dengan baik, hal ini didapat dari pengamatan. Respons siswa terhadap pembelajaran konsep dengan mengintegrasikan teknik skimming secara umum baik, hal ini ditunjukkan pada respons siswa tertinggi terdapat pada aspek kelima dan keenam yaitu siswa lebih termotivasi untuk belajar dan lebih berani menyampaikan pendapat persentase sebesar 85,87% dan tergolong baik sekali.

Abstract

ENSO (El Nino Southern Oscillation) is a phenomenon of sea surface temperature (SST) deviation in the Central and Eastern equatorial Pacific Ocean (Nino 3.4). ENSO phase consists of two deviations, namely El Nino and La Nina. La Nina has an impact on increasing rainfall in the Nino 3.4 region. Indonesia, which is part of the Nino 3.4 region, is affected by La Nina in the JJA period (June July August). With research conducted in Eastern Indonesia, Papua in the 2022 La Nina period has varying results. Through four observation points namely Sorong, Enarotali, Jayapura and Merauke. The most affected area of La Nina 2022 is Sorong while for the area affected by ENSO activity during the 11 years of observation (2013-2023) is Merauke with a significance value of 0.000306429; 0.000943892; 5.13748E-05. As for the time most affected by La Nina 2022 and ENSO activity 11 years of observation is in the same month of August with a significance value for the Sorong region of 0.011474481; Enarotali 0.006271735; Jayapura 0.431875715; and Merauke 5.13748E-05.

Abstract

This study investigates the swelling behavior and thermomechanical properties of polyethylene glycol (PEG) and silica xerogel composites using Dynamic Mechanical Analysis (DMA) and Differential Scanning Calorimetry (DSC). The composites were synthesized via a hydrothermal method and prepared by wet mixing PEG with silica xerogel. The analysis revealed that the interaction between PEG and silica xerogel significantly affects both the thermal and morphological properties of the composites. DSC data showed a shift in the glass transition temperature (Tg) and an earlier onset of thermal degradation in the PEG-Silica Xerogel 10 wt.% composite (P-SX10), indicating increased molecular mobility and reduced matrix stability. Notably, the swelling behavior was strongly influenced by temperature: as the temperature increased, the composites exhibited greater expansion and surface degradation, particularly in PEG-rich systems. This thermal sensitivity is attributed to the loosening of polymer–filler interactions and the partial debonding of matrix structures. The findings suggest that both composite composition and thermal exposure play critical roles in determining swelling characteristics and long-term structural integrity.

Abstract

This study analyzes the mechanical performance of femoral bone implants using two types of materials, namely Alloys and Cobalt Chromium Alloys, as well as two variations in implant length (72 mm and 24 mm, and 80 mm and 20 mm). Simulation was conducted using the Finite Element Method (FEM) to evaluate mechanical parameters, such as directional deformation, equivalent stress, maximum principal stress, and minimum principal elastic strain. The analysis results show that the Cobalt Chromium Alloys material has smaller deformation compared to the Alloys, indicating better stiffness and load-bearing capacity. However, the maximum principal stress value is higher in Cobalt Chromium Alloys, indicating a greater risk of stress concentration. Meanwhile, a longer implant length shows a more even stress distribution compared to a shorter length. This study provides important insights into the influence of material and implant length on its mechanical performance, and can serve as a basis for designing optimal implants for specific medical needs

Abstract

This review focuses on examining the synthesis and characterization of Carbon Nanodots (CNDs) from the utilization of Tandan Kosong Kelapa Sawit (TKKS) using the microwave method as an environmentally friendly approach. The resulting CNDs were characterized for their optical and structural properties to evaluate their potential application in the field of biosensors. The synthesis process involves carbonizing TKKS at 500℃ for 3 hours, followed by activation using a microwave at 450 Watts for 15 minutes. UV-Vis characterization shows an absorption peak at 280 nm, which indicates n-π* (C=O) and π-π* (C=C). Meanwhile, FTIR characterization aims to determine the presence of the carbonyl C=O functional group at 1990,98 cm-1 and the aromatic C=C bond at 1416,2 cm-1. The CNDs from TKKS exhibit photoluminescent properties and surface functional groupss that enhance adsorption performance and chemical reactivity. This research offers an efficient and sustainable method for synthesizing CNDs, while also being a breakthrough in utilizing biomass wate, particularly TKKS. The findings have the potential for developing carbon materials in environmental and energi applications.
