Abstract

Kabupaten Cilacap, Banyumas dan Banjarnegara termasuk wilayah paling berpotensi di Jawa Tengah. Data BPS tahun 2006-2015 menyatakan sektor wisatawan mengalami rata-rata pertumbuhan tiap tahun sebesar 18,07% dan sektor industri dengan pertumbuhan rata-rata PDRB sebesar 33,65%. Untuk mendukung perkembangan potensi-potensi tersebut diperlukan peranan tiap sisi moda transportasi, termasuk transportasi udara yang berlokasi di Bandara Tunggul Wulung Cilacap. Tujuan penelitian ini adalah untuk menganalisis peningkatan jumlah penumpang dan pesawat terbang sampai tahun rencana 2035, mengevaluasi kondisi eksisting serta menganalisis kebutuhan fasilitas udara meliputi runway, taxiway dan apron sampai tahun rencana 2035 sesuai pesawat rencana yang digunakan. Pertumbuhan jumlah penumpang dianalisis menggunakan Metode Kesesuaian Dengan Variabel Bebas dengan menganggap prosentase pertumbuhan jumlah penumpang sama dengan pertumbuhan jumlah wisatawan. Y= (Xn x 18,07%) + Xn, Y: penumpang pada tahun yang dihitung, Xn: penumpang tahun sebelumnya dan 18,07%: prosentase pertumbuhan rata-rata wisatawan. Analisis untuk tahun rencana 2035 menghasilkan total penumpang datang dan berangkat berjumlah 324.128 orang. Untuk pertumbuhan pergerakan jumlah pesawat terbang dianalisis dengan memperkirakan jumlah penumpang agar dapat ditampung sebanyak 80% (load factor 80%) tiap tahunnya oleh pesawat rencana ATR 72-500 dan Cessna C208B Grand Caravan. Sehingga menghasilkan total pergerakan pesawat pada tahun rencana 2035 sebanyak 8030 pergerakan dengan rincian 4380 untuk ATR 72-500 dan 3650 untuk Cessna C208B Grand Caravan. Rute yang ditempuh adalah Cilacap – Jakarta (60%), Cilacap – Bandung (20%) dan Cilacap – Semarang (20%). Sesuai hasil tersebut disimpulkan bahwa runway dan apron Bandara Tunggul Wulung Cilacap tidak mampu melayani kebutuhan sampai tahun rencana, sehingga runway dengan dimensi 1.400 m x 30 m perlu dilakukan penambahan panjang menjadi 1.600 m dengan lebar tetap 30 m dan apron dengan dimensi 125 m x 90 m juga perlu dilakukan penambahan panjang menjadi 257 m dengan lebar tetap 90 m, kemudian untuk taxiway dengan dimensi 110 m x 18 m tidak memerlukan pengembangan karena masih mencukupi. Frekuensi penerbangan yang sedikit pada tahun rencana 2035 menyebabkan hasil analisis tebal perkerasan tambahan rencana pada runway dan apron kurang dari tebal perkerasan eksisting. Oleh karena itu, tebal perkerasan tambahan runway dan apron pada penerapannya disamakan dengan tebal perkerasan eksisting. Tahapan pengembangan Bandara Tunggul Wulung Cilacap dimulai dengan perpanjangan pada daerah runway. Setelah itu, dilanjutkan dengan pengembangan pada daerah apron. Pengembangan bandara dilakukan secara bertahap supaya biaya yang dikeluarkan tidak langsung banyak dalam satu waktu, tetapi bertahap menyesuaikan kebutuhan.

Abstract

The construction sector is one of the major contributors to national economic development, but has great potential in environmental degradation. CO2 emissions have been used as a measure of the effect of human activities on the environment. One of the construction process that allegedly resulted in relatively large CO2e emissions is road projects. This study assessed the carbon footprint generated by the process of material production, material transport, and implementation of highway construction rigid pavement. Data is collected through direct observation of Palur Flyover Project and interviews with the project team, and project data obtained from the companies and government agencies. Road project reviewed start from STA. 0 + 350 to STA. 0 + 450 2 line of a 3 m width CO2e emissions calculations using the conversion factor from the literature. The total CO2e emissions produced during the process of rigid pavement is 92.9 tonnes of CO2e. The amount of emissions generated by the off site material production, material transport, concrete production and concrete pouring are 88 166 tonnes of CO2e (94.9%), 3,168 tonnes of CO2e (3.4%), 1,567 tons of CO2e (1.7%) respectively. Material production, cement production accounted for the largest CO2e emission (86,2%). Therefore alternative materials to cement are needed.

Abstract

Concrete is very common material used in reinforced concrete structure. There are several behaviors that influence its performance to the structure since its nonlinear behavior (Nawy, 1998). Nonlinear concrete behavior, besides can be obtained by experimental test result in laboratory, also can be conducted with one of the numerical simulation approach, namely finite element method. Based on the case, it will be conducted numerical modeling of concrete material with input the nonlinearity and orthotropic of concrete. Load-displacement response of concrete without reinforcement at small loading tends to linear then will be nonlinear when enters the cracking zone. Möhr and Kupfer failure criteria are used to evaluate the failure in concrete beam. Validation is a step conducted to view the validity from numerical study result that will be used as tools. Data resulted from experimental and numerical study is validated with research of Purkiss-Blagojevic (1993). This FEM program can be used as tools to analyze load-displacement response of concrete beam test specimen without reinforcement and predict the initial crack pattern happened.
