Abstract

One that deserves the attention of planners in designing a bridge structure is the design of the substructure. This is due to the fact that the structure below determines the quality and service life of a bridge and at present many cases of bridge structure failures are caused by failures of the substructure in holding the load acting on the bridge The aim of this research to test the characteristics of the soil and calculate bearing capacity of the foundation based cone penetration testing data and soil parameters at the Aifa bridge construction field in Fafurwar District, Teluk Bintuni Regency, West Papua Province. From the results of testing the soil characteristics in the laboratory, the type of soil at point 1 is the type of good to bad graded sand soil (SW-SP) with a water content of 17.72%, specific gravity 2.98, liquid limit (LL) = 16,746% included in the non-plastic category. While the location of point 2 is obtained from good to bad graded sand soil type (SW-SP) with a water content of 28.52%, specific gravity 2.73, liquid limit (LL) = 16.746% including the non-plastic category. To analysis of the calculation of the bearing capacity of the foundation Aifa bridge using data from the sondir test results for point 1 was obtained allowable bearing capacity (Qall) is 4.610,44 kN and for point 2 was obtained allowable bearing capacity (Qall) is 3.598,43 kN. For calculating bearing capacity of the foundation using soil parameter data for point 1 was obtained bearing capacity allowable (Qall) is 2.209,93 kN and for point 2 was obtained allowable bearing capacity (Qall) is 655,41 kN

Abstract

Stabilisasi tanah dengan menggunakan kapur merupakan salah satu metode stabilisasi tanah kimiawi yang paling populer dan paling banyak digunakan di Indonesia, hal ini disebabkan material kapur yang tidak susah diperoleh dan harganya relatif murah. Kondisi jalan di daerah Kabupaten Fakfak banyak mengalami kerusakan, hal ini berkaitan dengan kondisi tanah dasar (subgrade) jalan yang berupa lapisan tanah lempung. Salah satu jenis tanah lempung yang tidak memenuhi syarat adalah tanah lempung yang memiliki nilai plastisitas yang tinggi, karena memiliki potensi pengembangan yang besar dan daya dukung yang rendah. Penelitian ini bertujuan untuk menentukan nilai plastisitas tanah lempung di Kabupaten Fakfak yang telah ditambahkan dengan kapur dengan persentase kapur sebesar 4%, 8% dan 12%. Hasil pengujian menunjukkan tanah lempung di Kabupaten Fakfak yang telah ditambahkan dengan campuran kapur sebesar 4% diperoleh nilai batas cair (LL) = 13.45%, batas plastis (PL) = 11.88% dan nilai Indeks Plastisitas (PI) = 0.17%. Untuk campuran kapur sebesar 8% diperoleh nilai batas cair (LL) = 23.76%, batas plastis (PL) = 19.85% dan nilai Indeks Plastisitas (PI) = 3.91%. Sedangkan campuran kapur sebesar 12% diperoleh nilai batas cair (LL) = 25.16%, batas plastis (PL) = 16.20% dan nilai Indeks Plastisitas (PI) = 9.28%.

Abstract

The road conditions in the Fakfak Regency area have suffered a lot of damage, this is related to the subgrade condition of the road in the form of clay. One method that is widely used to improve the characteristics of clay that does not fulfill the requirements as a road subgrade material is to add fly ash. Aim of this study was to determine the value of clay plasticity before and after adding rock ash with the percentage of stone ash 8%, 16%, 32%. From the results of testing on clay soaked for 7 days can reduce the liquid limit value where the largest decrease is 15,24% of the original soil occurs in the addition of 32% fly ash with a value of 66,86%. The plastic limit value also decreased by 20,40% from the original soil with a value of 46,10% at the addition of 32% fly ash. And the plasticity index value experienced the largest decrease in the addition of 32% stone ash with a decrease of 0,97% from the original soil with a value of 20,76%. In clay soil which was brooded for 14 days the largest liquid limit value decreased which was 18.72% of the original soil occurred in the addition of 32% fly ash with a value of 64,11%. The plastic limit value also decreased by 21,77% from the original land with a value of 45,31% at the addition of 32% fly ash. And the plasticity index value experienced the largest decrease in the addition of 32% stone ash with a decrease of 10,32% from the original land with a value of 18,80%.

Abstract

Abstrak Perkembangan moda sektor transportasi khususnya moda transportasi udara dewasa ini mengalami perkembangan yang sangat signifikan. Hal ini disebabkan moda transportasi udara berupa pesawat terbang dapat membuat manusia berpindah tempat dengan sangat cepat, tidak seperti moda transportasi darat maupun laut yang memerlukan waktu yang lebih lama. Sehubungan hal tersebut maka dibutuhkan bandar udara yang memenuhi persyaratan dari segi keamanan dan keselamatan penerbangan. Tujuan penelitian untuk menganalisis dimensi landasan pacu (runway) serta mengevaluasi kelayakan dimensi landasan pacu (runway) Bandar Udara Torea di Kabupaten Fakfak Propinsi Papua Barat. Dari hasil penelitian yang dilakukan diperoleh dimensi panjang landasan pacu Bandar Udara Torea telah memenuhi persyaratan minimum yang ditetapkan oleh International Civil Aviation Organization (ICAO) tahun 2016 dengan panjang landasan pacu Bandar Udara Torea sepanjang 1201,8 m tetapi dari segi persyaratan untuk jenis pesawat ATR 72-600 belum memenuhi persyaratan sedangkan untuk standar dimensi lebar landasan lacu dan lebar bahu landasan pacu Bandar Udara Torea sesuai Peraturan Kementerian Perhubungan Direktorat Jenderal Perhubungan Udara Nomor : KP 39 Tahun 2015 tentang Standar Teknis dan Operasi Peraturan Keselamatan Penerbangan Sipil. Kata kunci: Moda transportasi, landasan pacu, bandar udara, pesawat ATR 72-600.   Abstract The development of transportation sector modes, especially air transportation modes, is currently experiencing a very significant development. This is because the mode of air transportation in the form of airplanes can make people move very quickly, unlike land and sea transportation modes which require a longer time. In this regard, an airport that meets the requirements in terms of flight security and safety is needed. The aims of the study was to analyze the dimensions of the runway and evaluate the feasibility of the runway dimensions at Torea Airport in Fakfak Regency, West Papua Province. From the results of the research conducted, it was found that the dimensions of the runway length of Torea Airport have met the minimum requirements set by the International Civil Aviation Organization (ICAO) in 2016 with a runway length of 1201.8 m Torea Airport but in terms of requirements for the type of aircraft ATR 72- 600 does not meet the requirements while for the standard dimensions of the runway width and the width of the runway shoulder of Torea Airport according to the Regulation of the Ministry of Transportation of the Directorate General of Civil Aviation Number: KP 39 of 2015 concerning Technical and Operational Standards of Civil Aviation Safety Regulations. Keywords: Modes of transportation, runway, airport, ATR 72-600 aircraft
