Abstract

Nuclear physics has contributed significantly to modern medicine, particularly through the use of radioisotopes in medical diagnosis. Radioisotopes such as Tc-99m, F-18, I-131, and Ga-68 are widely applied in imaging modalities including Single Photon Emission Computed Tomography (SPECT) and Positron Emission Tomography (PET), enabling non-invasive visualization of physiological processes at the molecular level. This literature review examines the physical principles underlying radioisotope production and decay, their pharmacokinetics in the human body, as well as the accuracy and clinical effectiveness of radioisotope-based diagnostic techniques. Analysis of 17 selected journal articles indicates that PET imaging using F-18-FDG achieves diagnostic sensitivity and specificity exceeding 90% for oncological applications, while Tc-99m SPECT demonstrates high reliability for cardiac and neurological assessments. However, key challenges remain including radiation exposure management, cost of cyclotron-produced radioisotopes, and limited generator availability in developing countries. The review concludes that continued advances in detector technology, radiopharmaceutical design, and image reconstruction algorithms are critical to improving the diagnostic accuracy and expanding access to nuclear medicine.

Abstract

Penelitian ini bertujuan untuk menganalisis efektivitas pengendalian piutang pada PT PLN (Persero) UID Sulselrabar selama periode 2020–2023. Penelitian dilakukan pada PT PLN (Persero) UID Sulselrabar karena kompleksnya pendapatan dari perusahaan tersebut. Metode yang digunakan adalah analisis kuantitatif deskriptif dengan teknik pengumpulan data melalui dokumentasi, menggunakan data primer dan sekunder dari laporan penjualan kredit dan statistik internal PLN. Hasil penelitian menunjukkan bahwa pengendalian piutang belum sepenuhnya efektif. Meskipun rasio Collection Periods (CP) secara konsisten memperoleh skor tertinggi stabil pada angka 4 sesuai standar Kementerian BUMN, hal ini tidak diikuti oleh kinerja rasio Receivables Turnover (RTO) yang justru fluktuatif dan berada di bawah standar industri. Kondisi ini mengindikasikan konversi piutang menjadi kas masih belum optimal, yang berdampak pada likuiditas dan efisiensi modal kerja perusahaan. Terdapat kesenjangan antara efisiensi waktu pengumpulan piutang dan efektivitas perputaran piutang. Dengan demikian, pengendalian piutang perlu ditingkatkan, khususnya dalam aspek peningkatan Receivables Turnover (RTO) agar pengelolaan piutang lebih optimal dan sesuai standar industri.

Abstract

This article aims to conceptually analyze the role of attitudes and awareness in shaping educator professionalism. This research uses a qualitative approach involving a review of various relevant scientific sources. Content analysis was used as a data analysis technique to identify, categorize, and synthesize relevant ideas. The results indicate that educator professionalism is not solely determined by technical skills but is also influenced by internal factors, such as professional perspective and reflective awareness. Professional awareness serves as an internal foundation that leads to meaningful pedagogical actions, while professional perspective represents internalized values. Consistent professional behavior is shaped by both through a dynamic and mutually reinforcing relationship. According to the findings of this study, educator professional development must be carried out comprehensively by combining skills, attitudes, and awareness through a reflective and ongoing approach.
