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.

Abstract

Research regarding earthquake vulnerability mapping studies based on fault patterns using focal mechanism data from earthquake data in the Bali Region has been carried out. This research aims to determine fault patterns in the Bali region using a focal mechanism from earthquake data for 1976-2021, determine the types of faults in the Bali region when analyzed using the focal mechanism method and determine areas that are prone to earthquakes in the Bali region. The data used are seismograph recordings obtained from the Global Centroid Moment Tensor (CMT) and the United States Geological Survey (USGS). The method used in this research is the focal mechanism method. The results of mapping the distribution of focal balls in the Bali region are that there were 9 earthquake events above 4 M, with 8 events being thrust faults and 1 being an oblique fault. Areas that are prone to earthquakes are in the East Bali region, specifically in Karangasam, and in general earthquakes occur in water areas or at sea. The results of the seismicity map of the distribution of earthquakes show that the depth of earthquakes in the Bali region varies. On the seismicity map, it can be seen that the most dominant ones are earthquakes in the deep and medium earthquake categories, but the most dangerous are earthquakes in the shallow depth category.

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.
