Abstract

Telah dilakukan penelitian mengenai analisis dosis serap pada pemeriksaan thorax pasien anak dengan pesawat sinar-X di Instalasi Radiologi RSUD Sanjiwani Gianyar. Penelitian ini bertujuan untuk menganalisis dosis serap yang diterima oleh pasien anak pada pemeriksaan thorax serta membandingkannya dengan batas dosis yang direkomendasikan oleh United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR). Penelitian ini dilakukan dengan metode kuantitatif menggunakan data sekunder dari hasil pemeriksaan thorax pasien anak berusia 1-15 tahun yang meliputi faktor eksposi (tegangan tabung, kuat arus, dan waktu eksposi). Data ini yang kemudian digunakan untuk menghitung dosis paparan dan dosis serap. Analisis statistik dilakukan dengan uji Kruskall-Wallis untuk menentukan signifikansi perbedaan dosis serap di RSUD Sanjiwani Gianyar dengan dosis serap yang ditetapkan oleh UNSCEAR. Hasil penelitian menunjukkan bahwa terdapat variasi dosis serap berdasarkan kelompok usia, di mana semakin tinggi usia pasien, semakin besar dosis serap yang diterima. Didapatkan dosis serap untuk kelompok usia 1-4 tahun yaitu:  mGy untuk pasien laki-laki dan  mGy untuk pasien perempuan. Untuk kelompok usia 5-9 tahun didapatkan sebesar mGy untuk pasien laki-laki dan  mGy untuk pasien perempuan. Sedangkan dosis serap kelompok usia 10-15 didapatkan sebesar  mGy untuk pasien laki-laki dan  mGy untuk pasien perempuan. Dosis serap yang diperoleh di RSUD Sanjiwani masih berada di bawah batas dosis maksimum yang ditetapkan oleh UNSCEAR yaitu: untuk kelompok usia 1-4 tahun sebesar 0,0300 mGy, kelompok usia 5-9 tahun sebesar 0,0400 mGy, dan kelompok usia 10-15 sebesar 0,0500 mGy.

Abstract

The research has been carried out on the HVL and TVL values ​​of the primary and secondary walls of the radiology installation radiology room at RSU Bali Jimbaran. The aims of this study were (1) to determine HVL and TVL values ​​on the primary and secondary walls in the x-ray room, (2) to determine the differences between HVL and TVL values ​​if the tube voltages are varied. In determining the HVL and TVL values, ​​the linear attenuation coefficient of the walls must be known. The linear attenuation coefficient was determined by measuring the wall thickness by using a caliper, and measuring the radiation dose rate before and after passing through the primary and secondary walls. The results of the analysis of the HVL and TVL values ​​on the primary wall were 1.668 cm and 5.540 cm, meanwhile on the secondary wall ​​were 1.915 cm and 6.362 cm. When the voltage was varied 40 kV, 50 kV, 60 kV and 70 kV, there was no difference in the HVL or TVL values. Based on the results of the analysis, the HVL and TVL values ​​on the primary and secondary walls have a significant average difference.

Abstract

Identification of groundwater using the geoelectric method in the housing area of the Udayana University boarding house, Bukit Jimbaran, Bali. Data acquisition was carried out using the Wenner configuration to determine the location of the aquifer depth with rock resistivity values. This measurement parameter is the resistivity value of the rock which is then processed using the Res2dinv software for data mapping. After that, aquifer interpretation and geoelectric data interpretation is carried out. The results showed that the aquifer in the residential area of the Bukit Jimbaran Bali Udayana University boarding house is located at a relatively shallow depth of 1.25-12.4 meters below the ground surface. On tracks 1 and 2 have 3 groups of resistivity values. The resistivity value of 2.16–37.5 Ωm with a depth of 1.25-12.4 meters is suspected as a type of tufa lithology. The resistivity value of 72.8–226 Ωm with a depth of 1.25-12.4 meters is suspected to be limestone associated with tuff. The resistivity value of 423–1363 Ωm with a depth of 1.25-12.4 meters is suspected to be limestone.

Abstract

The population administration in Jimbaran Traditional Village faces challenges of inefficiency and data inconsistency due to manual processes, especially in managing unique data structures such as NPK (Family Registration Number), NIKA (Traditional Community Registration Number), and Dadia. To address these issues, a web-based administrative information system was developed using the Prototyping method with the Laravel framework, MySQL database, and an interface built using Tailwind CSS and Alpine.js. The resulting system features key functionalities such as centralized master data management, dynamic input forms with automatic NPK and NIKA numbering, management of Traditional Family Card membership, and an integrated correspondence service module. The implementation results demonstrate that this application successfully serves as a functional solution for centralizing data, accelerating administrative services, and enhancing the accuracy of population data in accordance with the specific needs of the traditional village.
