Abstract

PDAM Jayapura is a government agency that operates in the field of providing drinking water services, apart from being a profit institution, it is also a social institution. PDAM Jayapura is tasked with providing clean water for the Jayapura City and Jayapura Regency areas. This research aims to identify the existing condition of the Jayapura City PDAM drinking water distribution system, analyze the availability, needs, and installed (distribution network) clean water needs in Jayapura City, and conduct an analysis of other alternatives in meeting Clean Water Needs in Jayapura City. The results of this research show that the coverage of clean water services by Jayapura City PDAM is still below national standards, using technological innovation to monitor and control the clean water distribution network system in real-time using sensor technology installed at each network point to identify and repair leaks quickly, based on the results of the planet 2.0 analysis, several parts of the pipe have very small velocities, therefore, the discharge coming out of the pipe is very small. The solution that can be made is to reduce the dimensions of the existing pipe so that the flow speed can be met and also by adding water pumps at various points that have a water speed of 0 m/s so that the water in the pipe can flow properly.

Abstract

Tami Weir is one of the weirs that has a vital role in human life. Sandtraps have an essential role in the operation of Tami bending. The objective of the evaluation and strategy for holding the Tami Weir sandtrap for irrigation water needs is to know the capacity of the Tami Weir sandtrap, the operation of the Tami Weir sandtrap, and the performance of the Tami Weir sandtrap. The method and technique for collecting data in this research is that data analysis is carried out after all the data has been collected. The results are adjusted to the purpose of writing and presented as conclusions. The results of this research are the capacity of the sandtrap during the flushing period, namely that a sediment volume of 73,134 m3 was obtained with a flushing time of fourteen (14) days. During deposition in mud pockets, the water speed will increase, and the deposition process will begin to decrease; at that time, the sediment will enter the channel. To overcome this situation, the sandtrap must be drained. The performance of the sandtrap at Tami Dam has decreased, where there is much alluvial sediment. The performance of sandtrap at Tami Weir cannot operate correctly due to the large number of sediment deposits, which are as high as the drain gate's threshold, making hydraulic draining impossible

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

The distribution of soil in Jayapura City, especially the Youtefa Bay area, consists of three dominant soil types that then form the stratigraphy of the local soil layer, namely allifial deposits, silt silt/silt clay, and fine, uniformly grained sand. Soil conditions like this have great potential for liquefaction, especially since this area is mostly passed by fault lines that have the potential to cause earthquakes. The groundwater table factor that is very close to the surface soil is also an important factor in the occurrence of liquifaction. There are 2 ways to analyze the potential for liquifaction, namely by laboratory test and from field test data. The approach to calculating field test data is CPT (Cone Penetration Test) testing. The results obtained were the Cyclic Stress Ratio (CSR) value and the Cyclic Resistance Ratio (CRR) value obtained by simulating seismic data using an earthquake strength of 6.5 on the riter scale and a pic ground acceleration value (0.3), then based on the results of the cone penetration test (CPT)/Sondir showed a maximum value of CRR 2.88, a minimum value of 0.21, a maximum CSR value of 3.70, a minimum value of 2.25. The maximum value of FS is 0.97, the minimum value is 0.07. There are 6 points at the research location that have the potential for liquefaction (Very High), namely points S1, S2, S5, S7, S8, S10, while 3 points with medium potential (High), namely points S3, S4, S9 for those with low potential (Low) S6.
