RANCANG BANGUN ALAT PRAKTIKUM KALORIMETER COFFEE-CUP PENGUKUR KALOR JENIS BERBANTUAN ARDUINO UNO
Get PDFPractical activities are a series of activities carried out to apply skills or practice something that requires practical tools in its implementation. The purpose of using practical tools is to meet the needs of practitioners in carrying out a process. One of the physics concepts that can be explained through practical activities is calorimetry. Specific heat is one of the observations made during the practicum using a calorimeter. The specific heat of the material is usually measured using a coffee-cup calorimeter manually. The obstacle faced by the practitioner during the calorimetry practicum is that the measurement of the dependent variables takes up the time and attention of the practitioner in the implementation of the practicum. The objectives of this research are (1) to design an Arduino Uno-based calorimeter practicum tool; (2) explain the work system of the Arduino Uno-based calorimeter practicum tool; (3) measuring the amount of heat on the Arduino Uno-based calorimeter practicum tool; (4) comparing the effectiveness of the Arduino Uno-based calorimeter practicum tool with the coffee-cup calorimeter practicum tool. This study uses a type of research and development (Research and Development) with a Nieveen design conducted in the Laboratory of Physics Education Study FKIP Jember University. Nieveen's design research procedures include Preliminary Research, Prototyping Stage, and Assessment Stage (summative evaluation). Based on the results of data analysis, there is a very strong relationship between the data from the measurement results of the design of the tool and the data from the results of the measuring instruments that have been standardized. The results of the measurement of the specific heat of the material using the design of the tool indicate a conformity with the previous theoretical study.

PERBANDINGAN KUALITAS CITRA PADA SOFWARE ASiR-V DAN NON ASiR-V DENGAN MENGGUNAKAN CT-SCAN GE
Get PDFAbdominal MSCT examination generally uses a high exposure factor because the abdomen is a thick part of the body so it requires a high exposure factor. Adaptive Statistical Iterative Reconstruction (ASIR) is an IR-based reconstruction algorithm that can optimize image quality even though it uses a low exposure factor so that the radiation dose produced is also low. GE Healthcare offers Adaptive Statistical Iterative Reconstruction (ASIR) and introduces ASIR-V as the next generation in , the authors compare the image quality using ASiR-V and non ASiR-V software produced by comparing CT-number, CT-number uniformity, noise , uniformity of noise and spatial resolution, it is known that the use of non ASiR-V software has a better standard of image quality than ASiR-V in the aspect of spatial resolution.

UJI RESOLUSI SPASIAL DAN SLICE THICKNESS PADA CT SCAN 128 DAN 16 SLICE DENGAN MENGGUNAKAN PHANTOM QUART DVT-AP
Get PDFCT-Scan adalah salah satu modalitas untuk diagnosis utama, kualitas citra dari CT-Scan sangat berpengaruh terhadap diagnosis. Untuk menguji kualitas citra CT-Scan diperlukan suatu alat ukur berupa phantom. Penelitian ini bertujuan untuk menganalisa penggunaan phantom Quart DVT-AP terhadap nilai resolusi spasial dan slice thickness pada CT-Scan 128 Slice dan 16 Slice. Uji resolusi spasial dan slice thickness dilakukan dengan menggunakan perhitungan dari citra digital. Phantom dipindai dengan melakukan variasi nilai slice thickness (2,5 , 5 , dan 10 mm). Penentuan nilai resolusi spasial dan slice thickness diperoleh dari nilai Edge Spread Function(ESF) menggunakan software bawaan phantom yaitu Quart CT-TEC dan juga Matlab. Kemudian digunakan juga phantom Gammex ACR untuk membandingkan nilai resolusi spasial dan slice thickness yang didapat menggunakan Quart DVT-AP. Hasil penelitian ini menunjukan bahwa phantom Quart DVT-AP mampu mengukur slice thickness pada CT-Scan 128 dan 16 slice dan sanggup mengukur sampai pasangan garis ke 6 yaitu 0,9 Lp/mm, lebih tinggi jika dibandingkan dengan hasil yang didapat menggunakan phantom Gammex ACR. Variasi ketebalan slice tidak mempengaruhi hasil pengukuran resolusi spasial dan slice thickness dan hasil perhitungan dari software CTTEC menunjukkan hasil yang sama baiknya dengan Matlab. Nilai resolusi spasial dan slice thickness telah dibandingkan dengan nilai lolos uji sesuai rekomendasi BAPETEN, sehingga perangkat CT-Scan masih layak untuk digunakan.

ANALISIS KEMAMPUAN BERPIKIR KRITIS PESERTA DIDIK DENGAN PENILAIAN TES DAN NON TES
Get PDFThis study aims to analyze students' critical thinking skills by assessing test and non-test to class X Mathematics and Natural Sciences students in one of the State Senior High Schools in Malang Regency. This type of research is a mix method research that combines quantitative research and qualitative research. This research was conducted on students of class X MIPA using a sample of 25 students by taking critical thinking skills tests in the form of multiple choice questions and essays as well as conducting non-test assessments. The results showed that students' critical thinking skills were still low because students were only able to determine physics equations but were unable to apply the formula to physics problems. Therefore, improving the variation of the learning system carried out by the teacher is highly recommended so that students are able to apply the formula to physics problems.
