Abstract

Sigil is an e-module creation software that can be used by high school teachers to help provide various teaching materials. However, the teacher's ability to use the Sigil software is still low where the teacher is still not able to apply the teaching materials in this e-module. E-modules can be used in online learning. One of the learning models that can be used is the Guided Discovery Learning (GDL) learning model. For this reason, society service for chemistry teachers who are members of the Padang Panjang Chemistry MGMP has been carried out in the form of a GDL-based e-module development workshop using the Sigil application. After the activity, it was found that the teacher understood and was able to create a GDL-based e-module using Sigil.

Abstract

A quantitative interpretation using a least-squares inverse based on the analytical expression from the first horizontal derivative (FHD) of moving average residual gravity anomalies is used to find depth and thickness of the fault. The problem of the depth determination has been transformed into the problem of finding a solution of a non-linear equation of the form f (z)=0. As a case study, this inverse is applied to carry out the fault parameters in the Kerinci segment. Two lines of gravity survey were carried out along and cross the Sumatra Fault System (SFS). The gravity anomaly pattern reflected a fault structure at northwest Sungaipenuh area in line along SFS and two-fault structure at western and eastern Sungaipenuh area in line cross SFS. The central depth and thickness of fault as a result inverse are 2.533 km and 0.815 km; 1.113 km and 1.985 km; 2.318 km and 4.195 km, respectively, for faults at northwestern, western and eastern Sungaipenuh area. The density contras is assumed - 0,43 g/cm3. Surface layer, basement and the layer faulted are reconstructed with density 2.22 g/cm3, 2.75 g/cm3 and 2.32 g/cm3, respectively. These results inverse agree with 2.5D forward model.

Abstract

Padang city is one of the regions of Indonesia that has potential in the tourism sector, one of which is beach tourism. The tourism sector is one of the largest sectors and the main mainstay for the economy in various countries, including Indonesia. Countries that rely on the tourism sector must pay attention to several factors that attract tourists, one of which is climate comfort. Climate information is a major factor in choosing a tourist trip. This study aims to analyze the level of climate comfort in the coastal tourism area of Padang City using the Holiday Climate Index (HCI) method. HCI uses climate parameters such as air temperature, humidity, wind speed, rainfall, and cloud cover. HCI calculation data in the form of observation data obtained from the Meteorology Climatology Geophysics Agency (BMKG) station at Minangkabau International Airport and the Teluk Bayur Maritime Meteorology Station from 2011-2020, direct measurement data from August to September, and questionnaires. The results of the HCI analysis show that the city of Padang is comfortable throughout the year, with the HCI value in the range of 58.6-71.6 which is categorized as acceptable to very good. The results obtained through direct measurements also obtained comfortable results throughout the day with HCI values in the range of 70-80. Perceptions of tourists interviewed also stated that overall tourists felt comfortable with the percentage of respondents as much as 74.1%. HCI can be used as a source of information to determine the value of climate comfort in tourist areas.

Abstract

One way to increase disaster knowledge is integrate disaster material into physics learning in schools. For tornado material to be easily raised in the physics learning process, learning resources are needed such as physics textbooks that are integrated with tornado material. However, not all physics materials can be integrated with tornado materials. So, it is necessary to first analyse the level of compatibility of tornado materials with physics materials in senior high school. This research is descriptive research with a qualitative approach. Research data is primary data collected through documentation studies. The primary tool used in this research is an analysis table of the compatibility of tornado material with physical material. The result of this research is the compatibility of tornado material with Senior High School physics learning material class XII semester 1 with a value of 0.316 and class XII semester 2 with a value of 0.348. In class XII semester 1, only 1 of 5 subject matter has compatibility to be integrated with tornado material, namely static electricity material with a compatibility value of 0.58. In class XII semester 2, there are 2 out of 6 subject materials that have a compatibility to be integrated with tornado material, namely electromagnetic radiation, and technology material with a compatibility value of 0,67 and 0,42. The research’s finding is that physics material for class XII in semesters 1 and 2 is less compatible for integration with tornado material.

Abstract

Rare earth elements are part of one of the strategic minerals and are included in the "critical minerals". Concentrations of rare earth elements are economically precious deposits that can be used as mining commodities. Pumice is the result of volcanic eruptions and it is one of the minerals containing the rare earth elements, one of which is found in Sigura-Gura, North Sumatra. The research aims to determine the composition of rare earth elements, the relationship between rare earth elements and magnetic mineral concentration, and to determine the concentration of magnetic minerals in pumice in Sigura-gura. The method employed is rock magnetic method with Bartington Magnetic Susceptibility Meter Sensor type B (MS2B), and X-Ray Fluorescence (XRF). Results indicated that Sigura-Gura pumice samples, and Sigura-Gura Waterfall have quite varied magnetic mineral concentrations with a range of values from 111,3 x 10-8m3/kg to 349,9 x 10-8m3/kg, with antiferromagnetic magnetic properties and grain types with almost no SP grains. Samples of Sigura-Gura pumice contain elements of Eu, Ce, and Y, while samples from Sigura-Gura Waterfall contain elements of Eu and Y. There is a correlation between the amount of magnetic minerals and rare elements, and the more elements are present in a sample, the lower the value that is produce, and the greater the percentage of elements obtained, the smaller (%) is obtained.
