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.

Abstract

This study examines the spatiotemporal patterns of built-up land changes in Kurik District, Merauke Regency, from 2015 to 2024. Utilizing Landsat 8 and 9 satellite imagery alongside supervised classification and Change Detection Analysis methods, the research aims to comprehensively model spatial and temporal dynamics of land cover transformation. Internal and external validations yielded classification accuracies exceeding 90% with kappa indices above 0.80, despite challenges arising from spectral similarities between built-up areas and low-density vegetation. The analysis reveals a significant increase in built-up land area driven by population growth and infrastructure expansion, particularly after 2020. High-density vegetation remains dominant but experienced decline due to forest degradation, followed by natural succession recovery. The distribution of built-up land varies across villages, reflecting heterogeneous development pressures and socio-economic dynamics. This study underscores the necessity of spatial planning management based on geographic information systems to balance development needs with sustainable agricultural land conservation. Limitations related to spatial resolution and field data present challenges for future research. Methodologically, the study offers valuable contributions to spatiotemporal modeling supporting sustainable agrarian regional planning in Papua and comparable areas.

Abstract

The Papua Mountains region has extreme geographical challenges that have an impact on the high need for road infrastructure maintenance. This study aims to analyze the relationship between the value of the Pavement Condition Index (PCI) and Life Cycle Cost (LCC), and to consider estimated inflation and net present value (NPV) as the basis for long-term budget planning. The study was conducted on the Tiom–Kuyawage (4.6 km) and Tiom–Balingga (2.7 km) roads in Lanny Jaya Regency. The PCI value in Tiom–Kuyawage has decreased significantly from 89.19 (2023) to 58.30 (2025), while Tiom–Balingga remains high at 87.44 (2025). The projected total maintenance cost for 20 years (2025–2045) shows a need of IDR 201.42 billion for Tiom–Kuyawage and IDR 122.62 billion for Tiom–Balingga. However, if calculated based on present value (NPV), assuming inflation of 3.09% and an interest rate of 5.04%, the actual need will be IDR 105.75 billion and IDR 64.58 billion, respectively. These findings suggest that the deterioration of road conditions (PCI) directly raises the cost of maintenance (LCC), and that the use of an NPV-based financial approach is important for budget efficiency. This study recommends a road maintenance strategy based on actual conditions, to be carried out periodically in the mountainous Papua region.

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

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.

Abstract

Access to safe and sustainable drinking water remains a major challenge in rural and mountainous regions of Indonesia, including Jayawijaya Regency, Papua. Community-Based Drinking Water Supply Systems (SPAM-BM) have been developed to expand water access; however, the long-term functionality of these systems is often constrained by weak institutional management and inadequate financial sustainability. This study examined the influence of the Management Group (KP-SPAM) and community contributions on the functionality of community-based drinking water supply systems in Jayawijaya Regency.A quantitative approach was employed using stratified proportional random sampling. Data were collected from 270 respondents selected from a population of 1,312 active household connections across 18 KP-SPAM units. Data collection methods included questionnaires, observations, structured interviews, and document reviews. The data were analyzed using validity and reliability tests, classical assumption tests, multiple linear regression, t-tests, F-tests, and coefficient of determination analysis.The results indicated that the Management Group variable had a positive and significant effect on SPAM functionality (? = 0.701; t = 12.467; p < 0.001), demonstrating that effective institutional management plays a crucial role in ensuring system sustainability. In contrast, community contributions did not have a significant partial effect on functionality (? = –0.092; t = –1.639; p = 0.102), although they may contribute indirectly through their relationship with management performance. Simultaneously, both variables significantly influenced SPAM functionality, explaining 42.65% of the variance in system performance.SWOT analysis further revealed that the management system is positioned in Quadrant I, indicating strong institutional capacity and favorable external opportunities. Strengthening KP-SPAM governance, enhancing financial transparency, and improving community participation are therefore recommended to ensure the sustainability of community-based drinking water services in Jayawijaya Regency.

Abstract

This study aimed to analyze the influence of Internal Project Factors and External Project Factors on the performance of road improvement projects in Papua Province. The research was motivated by the importance of successful road construction projects in supporting regional connectivity, particularly in Papua Province, which faces complex geographical, logistical, and project implementation challenges. Internal factors, including project management, human resource competence, heavy equipment availability, and contractor financial capacity, as well as external factors, such as weather conditions, social factors, and bureaucratic processes, were assumed to influence project performance. The research employed a qualitative approach using a survey method through questionnaires distributed to parties directly involved in road construction projects, including Commitment-Making Officials (Pejabat Pembuat Komitmen or PPK), Technical Activity Implementation Officers (Pejabat Pelaksana Teknis Kegiatan or PPTK), supervisory consultants, and contractors. A total of 196 respondents participated in this study. The data were analyzed using IBM SPSS Statistics 26 through validity testing, reliability testing, classical assumption testing, multiple linear regression analysis, partial significance testing (t-test), simultaneous significance testing (F-test), and coefficient of determination (R²) analysis. The results showed that Internal Project Factors (X1) had a positive and significant effect on Project Performance (Y), whereas External Project Factors (X2) did not have a partially significant effect. Simultaneously, both independent variables significantly influenced project performance. The coefficient of determination (R²) value of 0.434 indicated that the two independent variables explained 43.4% of the variation in project performance, while the remaining 56.6% was influenced by other factors outside the research model.

Abstract

The performance of road pavement structures is highly dependent on the bearing capacity of the subgrade. However, subgrade soils in many locations exhibit inadequate bearing capacity, necessitating soil improvement through stabilization techniques. This study investigates the effect of incorporating 2% DIFA Soil Stabilizer on the soaked CBR of soil–fly ash mixtures intended for road construction applications. An experimental laboratory program was conducted using natural soil mixed with varying proportions of fly ash, followed by the addition of 2% DIFA Soil Stabilizer. The testing program included the determination of the physical properties of the soil and soaked CBR tests to evaluate the improvement in subgrade bearing capacity resulting from the different mixture compositions. The experimental results demonstrate that the incorporation of fly ash in combination with 2% DIFA Soil Stabilizer substantially enhances the soaked CBR of the soil. The highest soaked CBR value of 9.10% was achieved with the mixture containing 15% fly ash and 2% DIFA Soil Stabilizer, representing a significant improvement over the untreated natural soil, which exhibited a soaked CBR value of only 1.00%. These findings indicate that the combined use of fly ash and DIFA Soil Stabilizer is an effective stabilization approach for improving the engineering performance of subgrade soils and may serve as a viable alternative for enhancing the bearing capacity of road subgrades
