Abstract

Kebutuhan lahan untuk permukiman di Kota Jayapura meningkat searah dengan pertambahan jumlah penduduknya. Dampak dari pertambahan jumlah penduduk ini adalah munculnya kantong-kantong kegiatan yang tidak saling menunjang, salah satunya permukiman baru yang berkembang di luar perencanaan sehingga terbentuk permukiman kumuh. Tujuan penelitian ini adalah menentukan strategi penataan kawasan permukiman kumuh perkotaan dan pengendalian munculnya kawasan kumuh baru di Kota Jayapura. Penelitian ini menggunakan pendekatan kualitatif deskriptif dan metode SWOT dengan responden dari para pakar (purposive sampling). Hasil analisis menunjukkan bahwa penataan kawasan permukiman kumuh yang dilakukan adalah lewat: sosialisasi peraturan, penegakkan peraturan, monitoring dan evaluasi, peningkatan ekonomi masyarakat pemilik ulayat dan menentukan posisi yang tegas antara pemerintah dan masyarakat hukum adat. Strateginya berada pada kuadran IV (WT) yang artinya meminimumkan semua kelemahan untuk menghadapi setiap ancaman. Untuk pencegahan terbentuknya permukiman kumuh baru, strategi yang diperoleh adalah SO (kuadran I) yaitu memanfaatkan kekuatan internal untuk mengambil keuntungan dari peluang eksternal. Pada aspek internal, terdapat faktor: masyarakat memiliki keinginan untuk memiliki lingkungan huni yang layak serta adanya tokoh masyarakat yang mensosialisasikan tentang lingkungan huni yang layak. Pada aspek eksternal, terdapat faktor: aturan atau undang-undang yang mendukung pencegahan terbentuknya kawasan kumuh baru dan program tahunan pemerintah pada peningkatan infrastruktur dasar perkotaan.

Abstract

This research involves several PLN substation projects in the Maluku and Papua regions. The subject of this study consisted of 25 respondents, namely 1 Project Manager, HSE Engineer and project supervisor. The questionnaire that has been given is then analyzed using the severity index method. The results of K3 risk identification on 44 risk variable indicators with high variables are found in the categories of product purchase and control, work safety in SMK3 and monitoring standards. The highest level of K3 risk to cost performance in substation construction projects in Maluku and Papua is the specification of the purchase of goods and services, the verification system of purchased goods and services, emergency planning and recovery, and labour health monitoring. The allocation of K3 risk in substation construction projects in Maluku and Papua is the most allocated risk shared between the owner and the contractor. The most K3 risk response is by holding and partially allocating to the owner by transferring. Recommendations for mitigation of K3 risks in substation construction projects in Maluku and Papua are by preparing procedures for work steps/related documents that are jointly supervised between the owner and owner. Then it is necessary to form an organization related to K3 that will be responsible for emergencies, work accidents and monthly reporting to the local Manpower Office.

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

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

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 %.
