Unit Rawat Jalan RSU Puri Raharja merupakan salah satu pelayanan kesehatan yang disediakan oleh RSU Puri Raharja. Unit Rawat Jalan RSU Puri Raharja berlokasi di Jalan W.R. Supratman, dimana jalan tersebut merupakan jalan kolektor yang memiliki kinerja ruas jalan yang cukup padat. Dengan adanya operasional dari Unit Rawat Jalan RSU Puri Raharja ini tentukan memberikan pengaruh terhadap kinerja lalu lintas di sekitarnya, yaitu Jalan W.R. Supratman dan Jalan Gadung. Dari hasil analisis didapatkan bahwa Jalan W.R. Supratman pergerakan terpadat pada hari kerja terjadi pada pukul 17.00 – 18.00 WITA dengan volume lalu lintas sebesar 2598,2 smp/jam. Volume lalu lintas Jalan Gadung pada hari kerja, jam puncak terjadi pada pukul 12.15 – 13.15 WITA dengan volume lalu lintas sebesar 445,0 smp/jam. Kinerja Jalan W.R. Supratman yang berada di depan lokasi Unit Rawat Jalan RSU Puri Raharja yang terkena dampak langsung dari operasional tersebut. Jalan W.R. Supratman pada jam puncak saat hari kerja memiliki V/C ratio sebesar 0,83. Jumlah bangkitan dan tarikan yang ditimbulkan sebesar 54,4 smp/jam. Kondisi eksisting merupakan kondisi saat ini dimana Unit Rawat Jalan RSU Puri Raharja telah beroperasi. Dengan adanya operasional Unit Rawat Jalan RSU Puri Raharja tersebut berdampak sebesar 2,09% terhadap kinerja lalu lintas di Jalan W.R. Supratman pada kondisi eksisting.

The current study is aimed at discovering ditch buried volcanic materials: geoelectric method assistance to minimize hazard loss. The research has been conducted at Bugbug Karangasem Bali. This covered by volcanic material from the eruption of Mount Agung in 1963 and before. Of course, there is a ditch as a land boundary. Based on the measurement results of the geoelectric method, it was found that there was a low resistivity area of 26.5 ?.m at a depth of about 7 m area A and 23.5 m (area B). Based on the excavation at several points, the thickness of the volcanic material layer in the study area is around 7 m. The landowners have claimed that their land is restricted by a ditch, which when Mount Agung erupted in 1963, had been covered with volcanic material; a ditch was made, but between the trenches made with the low-resistivity area A sideways again 11 m. The low resistivity is thought to be a buried ditch. As it is connected to the two cases above, namely the case of the results of geoelectric measurements and cases of landowners' suitability. The ditch that has been buried by volcanic material can be detected by geoelectric methods assistance.

Cikuray street, Garut is a collector road located 1 km from Garut Square, and on this road, there are many offices and shops for facilities and services. Therefore, Cikuray street experiences an increase in a traffic flow which causes noise. This study aims to analyze the level of traffic noise due to the volume and speed of vehicles. The method used in this research is a direct survey of the field and traffic noise modeling analysis using multiple linear regression analysis with the help of SPSS (Statistical Package of the Social Sciences) software version 26 for Windows. From the analysis, the highest volume of vehicles occurred on Saturday at 11,605 pcu/hour, with the average speed ranging from 34.00 – 38.00 km/hour and for a noise level of 84.55 dB(A) which means it has exceeded the standard. limit. permissible noise level. The relationship between volume and vehicle speed to traffic noise levels on Jalan Cikuray Garut using mathematical modeling is shown in the equation Y = 56.777 + 0.020X1 + 0.043X2 + 0.214X3 – 0.090X4 with R2 = 0.443. This shows that traffic noise (Y) can be explained by the volume of motorcycles (X1), the volume of light vehicles (X2), the volume of heavy vehicles (X3), and traffic speed (X4).
