Abstract

Kondisi topografi wilayah Papua, sangat bervariasi. Menurut catatan statistik yang ada, sebagian besar penduduk asli Provinsi Papua tinggal di kawasan pegunungan. Aksesi-bilitas menjadi syarat utama untuk lebih mempercepat pertumbuhan ekonomi demi kese-jahteraan mayarakat di pegunungan. Sebagian besar ruas jalan yang melewati kawasan pegunungan, dengan kelandaian yang sangat ekstrim banyak mengalami kerusakan. Sa-lah satu faktor dominan yang menyebabkan terjadinya kerusakan pada ruas jalan adalah akibat pergeseran dan pergerakan tanah. Penanggulangan longsoran baik di tebing atas, di daerah badan jalan maupun di lereng bawah jalan, sehingga dapat mencegah terpu-tusnya jalan maupun terjadinya kerusakan jalan yang lebih berat, menjadi target utama. Pendekatan secara geologis dan geoteknis menjadi syarat mutlak untuk mendesain sua-tu bangunan struktur yang digunakan dalam penanganan longsoran. Secara teknis, fak-tor utama penyebab longsoran yang terjadi di KM 51+760 (ruas jalan Wamena – Elelim) adalah aliran air permukaan di kiri jalan dari arah Elelim melimpas badan jalan dan me-nggerus lereng bawah jalan. Berdasarkan kondisi geologi regional diketahui bahwa kon-disi perlapisan tanah/batuan di lokasi longsoran adalah kelompok kembelangan tak ter-pisahkan (JKK) yang terdiri dari batu lempung, batu sabak, sedikit sisipan batu lanau: se-tempat batu gamping lumpuran dan batu pasir. Dengan kondisi tersebut salah satu al-ternatif penanganan yang direkomendasikan adalah badan jalan lama yang jenuh air di-bongkar sampai ditemukan lapisan tanah padat, kemudian timbunan badan jalan baru menggunakan sistem encapsulated dengan geotekstil woven..

Abstract

The issue of the logistics system is an important issue for the state of Indonesia as an archipelago. Effort to distribute commodities to destinations across the island and attempted export of transport costs become cheaper and faster is a thing to be achieved by all parties including the government of Indonesia. Logistical problems in eastern Indonesia are more complex than the western part of Indonesia. For example, the cost of transport from eastern Indonesia is more expensive than the western part of Indonesia. Therefore, PELINDO II as the company seeks to make the country a new facility in the form of New-port that will replace the port of Sorong Sorong. New-Sorong port will be the largest port in Eastern Indonesia. This paper makes an optimization model with the goal of optimizing shipping container and determines how much capacity should be made to the port of New-Sorong.

Abstract

The foundation is the main structure in a construction which functions as a support for the load or transmits the forces that occur above the construction and is transmitted into the hard soil. Pile foundations are part of the type of deep foundation that is widely used. In designing deep foundations using piles, there are several analytical methods to determine the bearing capacity of deep foundations.The purpose of this study is to calculate and compare the axial bearing capacity of single piles from the Meyerhoff SPT method data, the calendaring data from the Hiley method, ENR, WIKA, Eytelwein Chellis, Navy-Mc, Kay, Gates, Danish, and MSHoC, against the results of the test. PDA test axial bearing capacity. As for the calculation of the lateral bearing capacity using the Broms method.There is a difference in the value of the calculation results of bearing capacity and foundation settlement, both in terms of the calculation method and its location. Based on the calculation results of single pile axial bearing capacity with SPT data = 285,520 tons, calendaring data, Hiley = 336,994 tons, ENR = 50,156 tons, WIKA = 336,994 tons, Eytelwein Chellis = 88,718 tons, Navy-Mc, Kay = 5302,720 tons, Gates = 2802.460 tons, Danish = 9968.484 tons, MSHoC = 62.695 tons, while the results of the single pile axial bearing capacity using the PDA test obtained the results of = 392,000 tons. As for the calculation of the lateral bearing capacity of a single pile using the Broms method for the criteria for the pinned end pile foundation to be considered a long pile or not rigid, and the results obtained that the ultimate lateral force that can be resisted by the long wedged end pile is = 114.463 kg, and for The lateral allowable that can be resisted by the long pinned pile is = 38,154 kg, while the amount of deflection that occurs due to the allowable lateral force on the long wedged end pile foundation is 0.00549 mm. Differences in axial bearing capacity can be caused by differences in soil types, the way the test is carried out which depends on the accuracy of the operator and differences in the parameters used in the calculations.

Abstract

Jembatan Kali Nabire atau dikenal juga dengan nama Jembatan Bumi Wonorejo, yang merupakan jembatan rangka baja bentang 35 meter penghubung pada ruas jalan utama antara kawasan Bumi Wonorejo dan Karang Tumaritis di Kabupaten Nabire, telah mengalami kerusakan saat terjadi hujan deras. Penelitian ini bertujuan untuk mengidentifikasi kerusakan Jembatan Bumi Wonorejo di Kabupaten Nabire, dan menyusun program penanganan serta pemeliharaannya. Penelitian ini menggunakan pendekatan kualitatif dengan metode analisis deskriptif. Dari hasil observasi diketahui bahwa kerusakan abutmen pada jembatan disebabkan oleh gerusan air sungai yang meluap saat hujan deras. Proses gerusan ini juga terjadi karena adanya pengaruh morfologi sungai yang berupa tikungan dan penampang sungai yang tidak seimbang dengan volume air sungai waktu hujan deras. Gerusan yang terjadi di sekitar abutmen adalah akibat sistem pusaran (vortex system) yang timbul karena aliran dirintangi oleh abutmen tersebut. Aliran tersebut menyentuh abutmen dan ditambah dengan adanya aliran ke bawah (down flow). Kekuatan down flow akan mencapai maksimum ketika berada tepat pada dasar saluran sehingga bukan hanya abutmen tetapi dasar sungai juga tergerus. Untuk itu perlu segera dilakukan penanganan untuk mengantisipasi terjadinya luapan air sungai berikutnya mengingat kondisi cuaca yang sulit diprediksi di Kabupaten Nabire. Faktor alam berupa gerusan air sungai saat terjadi hujan deras, merupakan penyebab utama kerusakan jembatan yang tidak terhindarkan, sehingga penanganan yang bisa dilakukan adalah dengan selalu menjaga daerah aliran sungai bebas dari berbagai hambatan yang dapat membentuk pusaran air yang membahayakan jembatan dan memperkuat konstruksi jembatan agar tahan terhadap erosi air sungai pada kondisi iklim saat ini dan masa mendatang.

Abstract

Clay soils generally have low bearing capacity and are vulnerable to the water. Therfore, stabilization is necessary as an effort to increase the bearing capacity and improve the other parameters, one fo them by adding other materials such as fly ash and coral limestone powder as done in this research. The purpose of this research is to understand the effect of fly ash and coral limestone powder addition to the bearing capacity of clay soils after compaction process in term of CBR value by adding 15% fly ash and 0%, 10%, 20%, 30% coral limestone powder variations. The analysis results show that the original soil is an inorganic clay with 47,84% plasticity index. By adding fly ash and coral limestone powder variations decreases the plasticity index value to the lowest value 20,23%. The specific gravity increased on the 15% fly ash addition from 2,63 to 2,868 and decreased along with coral limestone powder addition to the lowest value 2,556. The maximum dry density decreased by adding 15% fly ash from 1,465 gr/cm3 on the original soil to 1,450 gr/cm3 and increased along with coral limestone powder addition to the highest value 1,522 gr/cm3. The optimum moisture content decreased along with the fly ash and coral limestone powder addition from 26,80% to 20,50%. The CBR value increased from the lowest value 0,47% to the highest value 15,29%.

Abstract

A study has been conducted on the typology of earthquake disaster-prone areas in the city of Jayapura and the suitability of Regional Spatial Planning (RTRW) for land use capacity in the city of Jayapura. The study onearthquake disaster-prone area typology aims to determine the distribution of stability levels of the area againstthe risk of earthquakes. This study employs a weighting matrix method for area stability based on the Minister ofPublic Works Regulation No. 21 of 2007 concerning Guidelines for Spatial Planning of Volcanic Eruption andEarthquake-Prone Areas (Department of Public Works, 2007). The research results indicate that the final score forthe city of Jayapura is between 30 - 45, which falls into all stability categories: stable and less stable. Thepercentage of area for each category is 97.81% for Stable Type A, 1.91% for Stable Type B, and 0.28% for LessStable Type C. The typology of earthquake disaster-prone areas in Jayapura based on stability scores falls intocategories A, B, and C. The study on the suitability of the Regional Spatial Planning (RTRW) for 2013-2033 with the land usecapacity in Jayapura was assessed by scoring data on land capacity and land use, followed by an overlay analysis.This resulted in a land capacity suitable for development of 57,039.39 hectares, or about 60.48% of the study area,while approximately 37,272.96 hectares, or around 39.52%, were deemed unsuitable.
