<![CDATA[The Research has been carried out on the level of earthquake hazard in the Bali region based on maximum ground vibration acceleration (PGA) and earthquake intensity. The data that used in this research were obtained from the BMKG and USGS catalogs. The value of the earthquake hazard level is calculated using the appropriate PGA empirical equation through a correlation test of several empirical equations, namely the Katayama, Mc. Guire, Faccioli, Singh et al, Ambraseys, and Wang & Tao with BMKG observation data.. Based on the correlation test, the Katayama equation (1974) was obtained with the smallest error value of 0.52. The calculation results show that the maximum PGA value ranges from 154-1944 gal and the earthquake intensity ranges from VII to X on the MMI scale with the highest hazard level in the Karangasem, Buleleng, and parts of Jembrana districts.]]>

<![CDATA[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.]]>

<![CDATA[This research aims to determine the effect of the problem based learning model assisted by video based laboratory on student learning outcomes in the material of optical devices. The population in this research were all class XI MIPA SMAN 1 Gunungsari. Sampling was carried out using a purposive sampling technique, so that class XI MIPA 4 was obtained as the experimental class and class XI MIPA 1 as the control class. The design used in this research was the nonequivalent control group design, where the two samples were given different treatment. The experimental class will be given learning treatment using a problem based learning model assisted by video based laboratory, while the control class will be given treatment with conventional learning. Learning outcomes are measured, namely in the cognitive domain which includes cognitive levels from C1 to C6. The instrument used was a multiple choice test with 20 questions. Study result data were analyzed using parametric statistics, namely t-test polled variance with a significant level of 5% or 0.05 and obtained a tcount of 2.49 and a ttable of 2.01. If tcount is greater than ttable, then Ho is rejected and Ha is accepted, so it can be concluded that the video based laboratory assisted problem based learning model has an effect on student learning outcomes in the material of optical devices.]]>

<![CDATA[The research has been done on 2D model of the subsurface structure of the hot springs in Angseri Village and its surroundings using the gravity method. The purposes of the research is to determine the distribution of gravity anomaly values, density values and subsurface rock structures. The results showed that the value of Bouguer anomaly was between 10-137 mGal, the regional anomaly was between 42-105 mGal, and the residual anomaly was between (-32)-(35) mGal. The modeling results showed that the subsurface structure of the study area was composed of lava rock (1.1-1.73 gr/cm3), tuff (1.61-2.52 gr/cm3), tuff breccia (2.51-2,79 gr/cm3), lava (2.8-2.89 gr/cm3) and volcanic breccia (2.9-3.2 gr/cm3), where volcanic breccia rocks as permeable rocks and tuff breccia rocks as cover rocks.]]>

<![CDATA[Research has been carried out regarding the position test of the drilled well against the aquifer at the Jimbaran Unud Campus on May 12, 2023. The borehole test was carried out using the Audio Magnetotelluric (ADMT) method. To ensure that the water needs of all students at Udayana are met, it is necessary to conduct research on drilled wells at Udayana whether they are suitable for aquifer positions (groundwater). The purpose of this study was to determine the suitability of the position of the drilled well to the aquifer in the ground behind the UNUD Rectorate Building. Based on the interpretation of the results of the research conducted in this paper, the aquifer position sought on line 1 is at a distance of 0–9 m and 21–50 m at a depth of 100–200 m below the ground surface, while on line 2 it is at a distance of 7–50 m at a depth of 100–140 m. Because the position of the Udayana drilled well is at 22.2 m on line 1 and 26.7 m on line 2 with a depth of 74 m, the Udayana drilled well is not yet in the aquifer position sought in this study.]]>

<![CDATA[This research aims to determine the effect of using a web-based virtual laboratory on students' physics problem solving abilities on Sound Waves material. The type of research used was quasi-experimental with a Pretest-Posttest Nonequivalen Control Group Design research design. The population in this study were all class XI students at SMAN 6 Mataram. The research sample was obtained using the Purposive Sampling technique, namely XI MIPA 2 with a total of 15 students as the experimental class and class XI MIPA 3 with a total of 15 students as the control class. The sample in this study was only 15 students because the data that will be taken and used as samples are only students who took part in both activities, namely pre-test and post-test, and the population in this study is approximately 100, so the number of samples that can be taken is at least less than 50% of the population size. The test instrument used is in the form of questions describing problem solving abilities. Before the problem solving ability test instrument is given, a trial of the instrument is first carried out, namely testing validity, reliability, level of difficulty and differentiability. The results of the analysis show that the average score for the physics problem solving ability of students taught using a web-based virtual laboratory is 68.60 and the average score for students taught without using a web-based virtual laboratory is 52.67. The results of hypothesis testing using the t-test obtained a calculated of 3.92. Because the obtained is greater than the value, then is accepted and is rejected. These results show the influence of using a web-based virtual laboratory on students' physics problem solving abilities in class XI sound wave material at SMAN 6 Mataram.]]>
