Abstract

The reservoir is the tendon of water in order to accommodate the excess rain water in the rainy season and its utilization in the dry season for various purposes, both in the field of agriculture as well as the interests of the community. To find out the cause of the crack wall of the reservoir Pilangbango Madiun, East Java, then do the test strongly press on concrete walls and soil investigations on the area of the reservoir. Spunpile 400 mm in diameter used by the mounting distance 200 cm and a depth of 12 m and pole mounted on the heels of concrete walls. Manual calculation of the results and analysis of the Finite Element program it can be concluded that in the presence of an additional retaining her 400 spunpile mm using a distance 200 cm and a depth of 12 m, retaining wall construction is then quite able to hold style pillow case and Sliding with style has a safety factor more than 1.5. So the movement of the sliding walls do not happen again.

Abstract

The Labuhan Bajo Multipurpose Terminal, located in West Manggarai, East Nusa Tenggara, has a very important strategic value as the main transportation hub for domestic and international trade. With the increasing demand for the efficient handling of cargo and passenger traffic, the construction of well-designed causeways and container yards is essential to ensure the terminal's long-term functionality and stability. The main objective of this study is to evaluate potential settlement patterns, identify potential risks associated with soil deformation, and propose appropriate mitigation measures to ensure safe and sustainable operation of the terminal. The findings from this research explain the importance of a thorough settlement analysis in large-scale infrastructure projects, especially those involving causeways and container yards. By understanding the response potential of the soil and implementing effective mitigation measures, engineers, contractors and policy makers can increase the resilience of terminals, minimize adverse impacts and ensure their long-term viability.

Abstract

The communal space for students in the university is important to support academic activities, considering that student activities on campus are not only in classrooms, studios, laboratories, and libraries. However, these shared areas are often poorly designed, leading to disruptions and discomfort for users. This research aims to gather preferences for student communal spaces at UPN "Veteran" Jawa Timur. The research objectives include identifying perceptions of the availability of student communal spaces and the activities carried out in these spaces. Furthermore, it aims to identify expectations for the atmosphere and facilities in these communal spaces. The results of the analysis of these expectations for the atmosphere and facilities are then linked to the types of activities. This research is conducted using a qualitative method. Data is collected through online questionnaires distributed to UPN "Veteran" Jawa Timur students and then analyzed using content analysis with stages including open coding, axial coding, and selective coding. The results show that psychological atmosphere factors, as well as thermal, auditory, and visual comfort, are dominant in the desired atmosphere by respondents. Additionally, the expected facilities are electronic and electrical.

Abstract

Slopes are the plains of the earth that create an angle of inclination on the horizontal side. Slopes are formed in two ways, naturally (geological processes) or man-made. Several ways that can be used to avoid the formation of collapse are retaining walls by identifying the effect of the safety factor on slope stability under existing conditions. In this study it was intended to plan slope reinforcement using sheet piles with the help of the plaxis program and using the manual calculation of the fellenius method to determine the safety factor for slope stability to overcome landslide disasters on glass bridges. The results of this study are the results of the analysis of the factor of safety from manual fellenius calculations and using the help of the Plaxis software before being given reinforcement and after being given sheet pile reinforcement.

Abstract

The process of embankment of the road body aims to create a safe and comfortable transportation route. However, the slopes on the road body often have limited stability and are susceptible to construction failure. The researcher intends to review the stability of the slope on the embankment with various variations in embankment height against the stability of embankment soil located on soft soil with a fairly deep depth. The need for geotextile reinforcement is influenced by the condition of the base soil itself. In geotextiles with the same Tult, the Tult of geotextiles used for all variations of embankment height in this study is 50 kN. The need for the number of geotextiles with the same embankment width and different variations in embankment height, the higher the embankment, the more geotextiles are needed.
