Implementation of the REACT Strategy Assisted by PhET Simulation to Improve Critical Thinking Skills on the Mechanical Wave Characteristics Topic
Jurnal Penelitian Pembelajaran Fisika
Vol 16
, No 2
(2025)
This study examines the improvement of students' critical thinking skills through the REACT Strategy assisted by PhET Simulation. The research employs a quantitative method with a pre-experimental one-group pretest-posttest design. The sample consists of 35 purposively selected 11th-grade students from a high school in Bandung, studying the characteristics of mechanical waves. Instruments include an essay-based critical thinking test (eight questions), and Student Worksheets. Data were analyzed...

This paper compares two single balanced mixer designs for ultra-wideband (UWB) of RF front-end at frequencies ranging from 3 to 10 GHz. The proposed mixer designs use two balun topologies for varying mixer performances. Thus, Design 1 incorporates a Coupled Line Balun and Design 2 incorporates a Branch Line Balun. Both designs make use of Skyworks' SMS7621 Schottky diodes, which have a low junction capacitance, and the Rogers RO4350B substrate, which has a dielectric constant of 3.48. The Coupl...

Gummy candy is a popular food product, but it is generally high in calories and low in functional content. Sungkai leaves (Peronema canescens Jack) are known to contain antioxidant compounds that have the potential to be developed as functional food ingredients. To overcome the high calorie content of gummy candy, this study developed a low-calorie gummy candy formulation with the addition of encapsulated sungkai leaf extract and a low-calorie sweetener. This study aims to determine the optimal...

PENENTUAN KADAR ALKOHOL DARI TAPAI UBI UNGU (Ipomoea batatas (L.) Lam) DAN TAPAI SINGKONG (Manihot esculenta Crantz) DENGAN VARIASI WAKTU FERMENTASI
Bhamada: Jurnal Ilmu dan Teknologi Kesehatan
Vol 16
, No 1
(2025)
Tapai merupakan makanan khas Indonesia yang dihasilkan dari fermentasi bahan makanan kaya karbohidrat. Kandungan utama singkong yaitu karbohidrat. Semakin tinggi kandungan karbohidrat dalam suatu bahan fermentasi, maka kadar alkohol yang akan dihasilkan juga lebih tinggi. Penelitian ini bertujuan untuk mengetahui kadar akohol pada tapai ubi ungu (Ipomoea batatas (L.) Lam) dan Tapai Singkong (Manihot esculenta Crantz) dengan variasi waktu fermentasi menggunakan metode spektrofotometri UV-Vis. Unt...

Analysis of Modified Exhaust Tip Geometry on Flow Behavior and Backpressure in Car Exhaust Systems for Electricity Harvesting
Advance Sustainable Science, Engineering and Technology
Vol 7
, No 2
(2025)
The efficiency of vehicle exhaust systems is critical for reducing backpressure and emissions, enhancing performance and sustainability of harvesting energy. This study investigates the effect of an additional body modification at the exhaust tip on pressure and velocity distributions using Computational Fluid Dynamics (CFD) simulations in SolidWorks. Simulations were conducted at inlet velocities of 10, 15, and 20 m/s. Results show that the modified design does not increase backpressure, with t...

Corrosion and carbonation pose significant risks to reinforced concrete structures, necessitating timely patch repairs, especially when using seawater-mixed mortar. This study evaluated the influence of binder type, cover thickness, corrosion protection methods, and exposure conditions on the durability of reinforced concrete. Specimens using Portland Pozzolan Cement (PPC) and Portland Composite Cement (PCC) with 3 cm and 5 cm cover depths were tested over 400 days. PCC exhibited superior corros...
