Abstract

The Tanjungpura University Hospital building is located in the city of Pontianak, which is situated on the equator and often faces the potential of lightning strikes, thus requiring the installation of an external lightning surge protection system. This study aims to design an external lightning surge protection system capable of protecting the Tanjungpura University Hospital building using the rolling sphere method. In the rolling sphere method, calculations will be made for the lightning strike distance (R), protection radius (Rp), protection area (Ax), and determination of protection angle (α). The University Tanjungpura Hospital building is at protection level IV, with a current strength of I = 16 kA and a lightning strike distance to the ground of 60.63 meters. The results obtained for using finials with the same height, hp = 1 meter, require hundreds of finials, while using a combination of finials and towers requires 68 finials. In the case of tower finials with a height hp = 10 meters, additional conductor wires are added or the catenary method is used with 14 conductor wires connecting 28 tower finials with a height of 10 meters, due to the areas outside the protection zone between these 28 final towers, necessitating the addition of conductor wires to expand the protection area of the rolling sphere method to protect the areas of the Tanjungpura University Hospital building.

Abstract

This study aims to determine the effect of human resources, technology, ATONs adequacy, ATONs maintenance, ATONs replacement, and ATONs security partially and simultaneously on the reliability of ATONs at Makassar Main Port. This research was conducted from February 2019 to April 2019 at the Makassar Class I Navigation District Office with the respondent sampling technique using a simple random sampling technique, taking samples from the total number of Civil Servants at the Makassar Class I Navigation District Office as respondents to determine the effect of independent variables on the dependent variable either partially or simultaneously. Data processing in this study used the SPSS for Windows Version 20 program. The results of this study indicate that, (1) Human resources, technology, ATONs adequacy, ATONs maintenance, ATONs replacement, and ATONs security partially have a positive and significant effect on the reliability of ATONs in Makassar Main Port. (2) Human resources, technology, ATONs adequacy, ATONs maintenance, ATONs replacement, and ATONs security simultaneously have a positive and significant effect on the reliability of ATONs at Makassar Main Port.

Abstract

Background: The third molar is the final tooth to emerge in the oral cavity, distinguished by variability in its developmental timing and the potential for its presence or absence, rendering it particularly susceptible to environmental fluctuations during odontogenesis. Consequently, the prevalence of third molar impaction or hereditary absence is the highest among all teeth. The third molar is linked to various clinical problems, such as impaction, ectopic eruption, hard and soft tissue disorders, and agenesis. Tooth agenesis refers to the congenital absence of one or more teeth and is among the most prevalent defects in individuals. Purpose: This study aimed at exploring the distribution of third molar agenesis cases according to gender, jaw involvement, affected side, and the quantity of missing teeth. Methods: This research employed a quantitative methodology characterized by a descriptive observational design. Data were acquired from secondary sources, comprising panoramic radiographs and medical data sourced from Wahab Sjahranie regional General Hospital (RSUD). Results: Agenesis's gender distribution showed more frequency in females (69.2%) than in males (30.8%). Agenesis mainly impacted the maxilla (44.2%), then the mandible (26.9%), then both jaws (28.8%). Furthermore, on the frequency of absent third molars, the most often occurring situation was the absence of one tooth (50.0%), followed by two teeth (28.8%), three teeth (9.6%), and four teeth (11.5%). Conclusion: The findings of this study demonstrate that third molar agenesis is more prevalent in females, predominantly occurs in the maxilla, is more frequently unilateral, and typically entails the absence of a single tooth. Keywords: agenesis, panoramic, third molar
