Abstract

There are many landslide points on the Arso-Waris National road, so it is necessary to conduct research on the potential for landslides from the physical and shear strength properties. The analysis method uses Slope/W software from GeoStudio, using the Bishop and Fellenius analysis method. The results of the study on 4 points along the Arso-Waris section, showed that with a decrease in the value of the shear strength parameter, both the cohesion value (average decrease of 69.91%) and the value of the shear angle (average decrease of 92.77%) in the reverse analysis resulted in a decrease in the value of the safety factor score by 71.5% (Bishop Method) and 71.11% (Fellenius Method). The value of the smallest (critical) safety factor is 0,498, located at point 4 KM.105+193 in combination loading, by using Fellenius method. Changes in physical properties and shear strength have the potential to reduce safety factor so that there is potential for landslides.

Abstract

This study was conducted to determine the existence of subsurface aquifers and the distribution of groundwater-surface depth in Jayawijaya Regency, Mountainous Papua Province. The background of this research is the need for optimal groundwater management in areas with high topography such as Wamena City. The method used was a geophysical survey with the Wenner-Schlumberger configuration resistivity geoelectric technique to identify the aquifer layer. Primary data was obtained through direct measurements using geoelectric devices and GPS, while secondary data was obtained from related literature. The results showed that there were free aquifers with a depth of 25-105 meters and depressed aquifers at a depth of 145-270 meters in various research locations. The distribution of this aquifer is highly dependent on local geological conditions, with the availability of groundwater quite high in some areas and minimal in other areas such as Kampung Sabulama and Wasawa. In conclusion, the resistivity geoelectric method is effective for mapping the distribution of aquifers, which can further be used as a basis for groundwater management in the study area.

Abstract

A successful and high-quality learning environment requires adequate educational facilities. But the disparities between urban and rural areas frequently impact the standard of facilities in both places. The comparative descriptive study design is used to gather data from direct observations and interviews with the school's head and representatives from the other two relevant institutions. The information gathered covers details about the accessibility of facilities, the state of school buildings, and other learning support facilities. The study's findings indicated that facilities for sports and extracurricular activities are more readily available in urban than rural locations. The city has a state-of-the-art educational facility with practical classrooms, sufficient libraries, and labs. Urban areas also have more reliable and open internet connections. On the other hand, rural schools have physical limitations due to the size of the classrooms and the lack of adequate learning support resources. The availability of educational amenities between urban and rural schools differs significantly, in conclusion. For all kids, regardless of where they are in the world, the infrastructure and technological accessibility issues in rural schools need to be given more consideration. To achieve educational equity throughout the Indonesian area, governments and stakeholders must make improvements and use funds wisely.
