Abstract

At the open pit mining, a place is needed for storing overburden material which is commonly referred as a disposal. In some cases, overburden material is stockpiled in void. Overburden material stockpiling activities require good planning. This research was conducted in the open pit "X" Site Sambarata PT. Berau Coal, East Kalimantan. The purpose of this study is to calculate the value of the safety factor of the slope, calculate the probability of failure and to analyze the effect of the water level on the slope stability. This study used the Bishop method with pseudostatic conditions and fully saturated groundwater conditions. From the results of this study it was found that the value of the slope safety factor in the study area ranged from 0.993 to 1.33 and the value of the probability of failure is 17.1 to 35.6%. The value of the factor of safety and the probability of failure is influenced by the geometry of the slope, distributed load, seismic load, and the height of the water level where the higher the water level in the pit, the value of the slope safety factor is higher and the value of the probability of failure is lower.

Abstract

The growth of tourism villages has become a key strategy for addressing challenges faced by the tourism industry during the pandemic. It's playing a big role in boosting Indonesia’s creative economy. This research focuses on identifying what drives tourists to visit these villages and which factors are most important in their decision-making. By reviewing various studies, key factors emerged: tourism product attribute (attraction, amenities, accessibility), tourist services, location, how easy it is to get there, and the impact of electronic word-of-mouth (e-WoM). Results showed that the main factors influencing tourists' choices were the attractions themselves and e-WoM. These insights can help village managers fine-tune their marketing efforts. Additionally, understanding that tourists often look for an escape from their daily routines or seek relaxation can help in designing more attractive travel packages. This research adds to existing academic discussions by offering a detailed look at what influences tourist choices in rural tourism, especially in Indonesia. Future studies should look at broader databases and include international perspectives to enrich the knowledge around global practices for tourism villages.

Abstract

University of Padjadjaran (Unpad) as a means of education and research has need of water large quantity. Until now meeting the needs of water was carried out as a conventional namely the usage of groundwater. Through the passing of time, the constant use of groundwater and land use change in the catchment area may pose a risk of ground water crisis. Rainwater in the university environment has large potential with an average annual rainfall is 961.92 mm. The concept of rainwater harvesting by using potential water which be runoff will become the source of water to the fulfillment of a need. Unfortunately, rainwater that become runoff can contain bacteria and chemical contents that may be harmful to health. It is necessary for the screening process using filtration and membrane technology that can clean water and produce safe water to drink.
