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

Access to clean water is a fundamental need for supporting healthier and cleaner living conditions, which is critical for achieving the Millennium Development Goals (MDGs). In East Sarmi District, Sarmi Regency, the community relies on surface water, groundwater, and untreated rainwater as primary sources of raw water. This study aims to evaluate the potential of these water sources to meet health standards and the community's future water needs. The research focuses on the condition of the Sewan River, a significant water source in East Sarmi District, and its capacity to fulfill the clean water demands. The study uses SWOT analysis to assess the potential of the Sewan River as a reliable source. The findings reveal that the required clean water in Sarmi District by 2043 is 1.46 liters/second, which is equivalent to 0.0016 m³/day. The Sewan River currently provides 198 liters/second, indicating that its water supply is more than sufficient to meet future needs. Furthermore, both the community and the local government support the development of water resources in the region. This research contributes to identifying sustainable water sources and offers recommendations for improving water management in East Sarmi District to meet health standards and enhance the quality of life.

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 opening of new land to be used as a location for housing development (KPR) or Shop Houses (Ruko) as residential and business places that may technically not meet the requirements and standards for erecting a construction building in the area, let alone on a mass basis. Because the potential for construction failures is very prone to occur, such as land subsidence (Settlement). These factors must be found to increase the carrying capacity of the land so that it can meet the requirements to erect a construction building that is safe, economical and at the same time the life of the building can be longer. Based on the description mentioned above, the researcher is interested in modeling carried out in the engineering laboratory of Cenderawasih University with sakla 1; 50, this research was carried out there are three types, namely soil without reinforcement, soil with a 6 cm diameter gravel column reinforcement with a depth variation of 4 cm and 8 cm, and soil with a 6 cm diameter used tire column with a depth variation of 4 cm and 6 cm. This test is carried out by applying pressure or load in a vertical direction, The tool used is in the form of a hydraulic jack by paying attention to the load reading dial and the drop reading dial until the reading is fixed or the drop dial does not show any further decline. Based on the results of the analysis of this study, it was obtained that: The test was applied on soil without reinforcement obtaining an ultimate load of 950.00 kpa with a qijin of 380.00 kpa, soil with the reinforcement of gravel columns with the greatest carrying capacity of 1,849 Kpa with a qijin of 739.444 kN or producing a carrying capacity 95% greater than the soil without reinforcement.

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.
