Abstract

Clean water is one of the important aspects that must be prioritized in urban planning. The higher the standard of living of the community, the need for clean water will also increase. However, the fulfillment of adequate clean water needs in Supiori Regency is still not optimal. Based on the Minister of Public Works Regulation No. 14/2010, the coverage of drinking water services in Supiori Regency is classified as poor, with a clean water service level of less than 50%. Optimization efforts are needed to optimize and distribute clean water services in Supiori Regency meet the target of clean water services and create a sustainable community life. The research method uses three types of analysis. First, the ratio of clean water services in the settlements of Supiori Regency was analyzed using a calculation method that refers to the standard of clean water needs and availability. Second, the analysis of clean water services was conducted based on community perceptions. Third, this study analyzed the factors that influence clean water services using multiple linear regression. Descriptive analysis was used to identify optimization steps. The results showed that the ratio of clean water services in South Supiori District only reached 30.38%, while in East Supiori District, it was lower, at 19.78%. Based on community perceptions, 93% of the population in South Supiori District and 75% in East Supiori District have not used the Water Supply System. Regression analysis shows that in Supiori Selatan District, factors affecting clean water services include pipe distance, community participation, and number of family members. In East Supiori District, the influencing factors are pipe distance, management, and maintenance of clean water. So, there are optimization efforts that can be done, among others, through mapping services based on regional conditions. For areas that are difficult to reach by SPAM services, the community can utilize the nearest water source to meet their clean water needs independently.

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 Trans Papua road network spans 3,259.45 km, comprising 58.24% national roads (1,898.32 km) and 41.76% strategic roads (1,361.13 km). A specific issue arises on the Trans Papua Segment IV (Jayapura–Elelim–Wamena), where the geometric design of the road does not align with the standards set in the Ministry of Public Works and Housing Regulation No. 5 of 2023 regarding technical requirements for road design. This non-compliance poses risks of traffic accidents and impacts travel time, particularly for essential vehicles like fuel supply trucks, which cannot navigate certain segments due to the road's steep gradient (overgrade). This study aims to analyze the compliance of the geometric design on the Jayapura–Elelim–Wamena road segment with the established technical standards and its alignment with the central government's policy to enhance the local economy and ensure equitable pricing in mountainous regions. The research findings reveal that while road handling in Segment IV Jayapura–Elelim–Wamena has been managed by the BPJN Jayapura and BPJN Wamena, the existing geometric conditions do not meet the requirements of Permen PUPR No. 5 of 2023. The current policy focuses on maintaining the functionality of the road through preservation work packages rather than addressing the design deficiencies. This study underscores the need for more comprehensive upgrades to meet regulatory standards for safe and efficient road use.

Abstract

Low shear strength will result in low bearing capacity and large (Settlement), even excessive settlement, and the compressibility of the soil will affect the shrinkage of the soil due to the influence of the groundwater level that occurs and will affect the stability of the buildings on it. soil stability through soil improvement techniques and soil reinforcement techniques. Soil improvement techniques are soil stability measures by improving the original soil characteristics, until they meet the technical requirements required by construction, such as increasing the bearing capacity and shear strength of the soil, decreasing soil compressibility, increasing or decreasing soil permeability, and so on. In this study, it was applied to unreinforced soil with a bearing capacity of 950.00 kPa with a qijin of 380.00 kN and with a decrease of 1.861 mm or 4.0%. Soil with reinforcement has a better carrying capacity compared to soil without reinforcement, so that soil with reinforcement gets greater load behavior, from the experiment with reinforcement of wooden piles (CK 8 I) gets a maximum load of 25.10 kN with a decrease of 5.90 mm or 11.80%. The maximum load acting on the ultimate unreinforced (pu) soil on the original soil is 13.68 kN with a qijin carrying capacity of 380.00 kN. Soil with wood pile reinforcement maximum working load of 25.10 kN with a drop of 5.90 mm or 11.80 %. Soil with reinforced cast-concrete maximum working load of 23.50 kN with a drop of 4.50 mm or 9.00 %.

Abstract

The Lumpsum contract system with a Fix Price value with the financing system is Contractor's Full Prefinanced (CPF). This system will be implemented for owners to ease costs, considering that financing is charged to contractors 100%. and paid 30 days after the minutes of the PHO were signed by both parties, Rato (20018). One of the contract systems used in the contract for the purchase of a construction project is the Remeasure Contract (Unit Price). Bridge construction infrastructure is one of the land transportation infrastructure that has an important role in the distribution of goods and services as well as mobility for the community and other economic sectors. Therefore, bridge construction plays a very important role in economic growth in a region. From the above background, the author needs to re-analyze a construction project in the Mountainous Papua Province in terms of the quality of work of the contractor, the lumpsum contract system, and the unit price contract system in the bridge construction project. The results of this study are as follows: the effect of the Lumpsum contract system on the quality of contractors' work in road and bridge construction projects is GOOD. The effect of the Unit Price contract system on the quality of contractors' work in road and bridge construction projects is GOOD. There is no effect of the contract system on the quality of contractors' work on road and bridge construction projects in Papua Mountainous Province.
