Abstract

Selama ini penelitian hanya fokus pada cara dan pemakaian alat proteksi untuk pasien dan pekerja radiasi. Bahan proteksi paparan radiasi ionik lain yang penting bagi pasien, pekerja radiasi, bahkan masyarakat umum adalah dinding ruangan radiologi. Dinding ruangan radiologi mempunyai syarat tertentu, seperti ketebalan, komposisi bahan, dan warna. Dinding harus berwarna putih agar bersih dari kotoran maupun mikroorganisme. Dinding ruangan tidak terkena paparan langsung, melainkan melalui hamburan, sehingga dosis paparan rendah. Dengan memvariasikan tegangan tabung sinar X seperti yang digunakan pada diagnostik, dilakukan pengamatan terhadap perubahan komposisi cat dinding dengan X-Ray Flourosence (XRF). Hasil penelitian menunjukkan perubahan besar pada laju dosis 1,19 mGy/s atau pada tegangan tabung 80 kV. Senyawa yang terkandung dalam cat menurun persentasenya, bahkan senyawa K2O dan Nb2O5 tidak terdeteksi. Hal ini menunjukkan bahwa jumlah pemakaian sinar X konvensional yang tinggi akan meningkatkan kerusakan cat dinding ruang radiologi. Kata kunci: Sinar X, cat dinding, X-Ray Flouroawnce (XRF), diagnostik

Abstract

This research is a quantitative research with an explanatory approach.. The data used in this study is primary data that the researcher obtained directly from various sources or commonly referred to as primary sources from 295 Pose sandal customers spread throughout Indonesia. The data obtained by the researcher was analyzed using the smart PLS 4.0 analysis tool. The result in this article show that the Brand Awareness variable can have a positive relationship direction and a significant influence on Purchasing Decisions because the P-Values ​​value is positive and below the 0.05 significance level, namely 0.001. T. The result of the P-Values ​​value of 0.001 means that Brand Awareness can make a product more famous, widen the product's market share, and ultimately can influence Purchasing Decisions. In addition, the User Generated Content variable can also moderate the influence of the Brand Awareness variable on Purchasing Decisions because the P-Values ​​value also tends to be positive and is below the 0.05 significance level, namely 0.000. Thus, it can be concluded that the first and second hypotheses in this article can be accepted.
