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. \u0000 \u0000Kata Kunci : Edge Spread Function(ESF), Phantom Quart DVT-AP, Resolusi Spasial, \u0000 Slice Thickness, Software CTTEC","PeriodicalId":33966,"journal":{"name":"Gravity Jurnal Ilmiah Penelitian dan Pembelajaran Fisika","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83433525","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thermodynamics is rarely taught with practical activities. The research was conducted to investigate the performance of motorized vehicle engines related to fuel efficiency. Machine performance can be taught with a Project Based Learning approach. Modification of the volume of the combustion chamber on the cylinder head is done to change engine performance. The pressure and power possessed by a vehicle engine are the main components of engine performance. The results of data analysis on the modification of the combustion chamber obtained the diameter before being modified from 50 mm to 54 mm, TMA from 49.5 mm to 54 mm, TMB from 5.5 mm to 3.5 mm, compression ratio from 9: 1 to 15: 1. This causes fuel consumption from 86.5 ml to 89.5 ml at 6000 rpm, from 62.33 ml to 64.166 ml at 4000 rpm, from 48.166 ml to 50 ml at 2000. This modification increases energy. The heat entering the system is 0.1 kJ, the thermal efficiency increases by 0.1%, the net work increases by 0.4 kJ, and the average effective pressure increases by 0.3 N/cm 2 .","PeriodicalId":33966,"journal":{"name":"Gravity Jurnal Ilmiah Penelitian dan Pembelajaran Fisika","volume":"23 2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78445526","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Population growth and increasing consumption needs of people's lives impact high waste production. People's habit of littering can have a negative impact on health and the environment. The solution that can be given to overcome this problem is to provide curative and preventive measures. Trash boxes are often one of the reasons to throw trash in its place. So we need a trash box that can make garbage disposal easier. Therefore, a digital-based smart box or smart box was developed by utilizing the Arduino Uno microcontroller. The smart box was developed using the HC-SR04 sensor. The trash box is designed with the working principle that the trash box can open and close automatically when someone throws out the trash. In addition, the purpose of developing this garbage box can be used as a source of learning physics in the application of ultrasonic sensors. This study uses the ADDIE model development method. The results showed that the digital-based smart box was declared very feasible, with a feasibility percentage of 89%. Meanwhile, regarding the results of utilization as a source of learning physics, user responses from teachers and students have a percentage of 89% with very good criteria.","PeriodicalId":33966,"journal":{"name":"Gravity Jurnal Ilmiah Penelitian dan Pembelajaran Fisika","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84592923","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
