ABSTRACTConfinement in concrete can increase ductility and compressive strength of the column (P0). While the use of steel fibre can also increase the ductility of concrete. In this study, the steel fibres as an additive in concrete short columns confined, and short columns were given concentric axial loads until they reach collapse. The results showed that the use of steel fibres in concrete can increase P0. The compressive strength (P0) of a confined short column without steel fibre was 52.06 ton to 63 ton, while on a short column with steel fibre was 57.68 ton to 69.28 ton. Those indicated that concrete short columns with steel fibres can increase the compressive strength, but in this study, the effect of the Ast (column longitudinal reinforcement area) has not yet. Keywords: Compressive strength, Confined, Short column, Steel fiber.ABSTRAKKekangan pada beton dapat meningkatkan daktilitas dan kuat tekan kolom (P0), sedangkan pemakaian serat baja (steel fiber) juga dapat meningkatkan daktilitas beton. Dalam penelitian ini serat baja sebagai bahan tambah pada beton kolom pendek terkekang, dan kolom pendek dibebani gaya aksial konsentris sampai mencapai runtuh. Hasilnya menunjukkan bahwa pemakaian serat baja pada beton terkekang dapat lebih meningkatkan P0. Kuat tekan P0 pada kolom pendek terkekang tanpa serat baja didapat 52.06 ton sampai dengan 63 ton, sedang pada kolom pendek terkekang memakai serat baja didapat 57.68 ton sampai dengan 69.28 ton. Hal ini menunjukkan bahwa kolom pendek beton terkekang dan diperkuat serat baja dapat meningkatkan kuat tekan kolom pendek, tetapi dalam penelitian ini kuat tekan kolom pendek belum mengamati pengaruh pemakaian Ast (luas tulangan longitudinal kolom).

This research is aimed to know the process of waste transportation on theopen-channel using numerical model. This model is chosen because of some reasons, for example the complication of the river tissue, the influence of ebb which causes difficulty to conduct analytical problem solving. The other excess of this numerical model is cheaper and easier than conducting measurement of waste rate in the field.The equa~on of waste transportation can be formulated as the two physics phenomenon, Le. advection and diffusion process or long dispersion of river. In the solving of equation of waste transportation, each of the components was analyzed separately. The advection part was done first, and the diffusion part was finished then. The advection equation was done using Lagrange interpolation, and the diffusion equation was done using differential method to explicit scheme.The result of the research shows that the use of Lagrange interpolation upto order 4 is still be good enough to finish advection equation for numberCourant 1, 0,75 and 0,5. For number Courant 0.25, numerical mistake causingconcentration degradation of 2.3 0/0. In the diffusion equation, the result of computationusing differential method up to explicit scheme yielding degradation ofwaste concentration from 10 gr/I become 4,96 gr/I for the diffusion coefficient ofKx =10 m2/sc and become 3,73 gr/I for the diffusion coefficient of Kx = 20 m2/sc.

ABSTRAKJumlah pengunjung maksimal objek wisata pantai di Kabupaten Gunungkidul antara Tahun 2014-2017 sejumlah 18.369 jiwa per bulan, sehingga jika terjadi tsunami potensi korban sangat besar, maka untuk meminimalkan korban jiwa saat terjadi tsunami diperlukan suatu kebijakan untuk pengurangan risiko terhadap bencana tersebut dengan strategi penyelamatan yang komprehensif dan upayanya menyediakan Sistem Peringatan Dini Tsunami. Tujuan penelitian adalah menentukan tempat evakuasi tsunami pada objek-objek wisata pantai di Kabupaten Gunungkidul berdasarkan FEMA P646 dan membandingkan dengan hasil penentuan tempat evakuasi tsunami yang dilakukan oleh BPBD Kabupaten Gunungkidul kesesuaian dengan pedoman FEMA P646. Penelitian ini menggunakan metode kuantitatif dengan teknik analisis deskriptif yaitu menganalisis jalur dan tempat evakuasi (TE) dengan berpedoman dengan FEMA P646 untuk menentukan tempat evakuasi tsunami, ketinggian elevasi merupakan bahan dasar dari analisis yang dilakukan. Oleh karena itu, perlu dilakukan pengumpulan data ketinggian elevasi, waktu tiba tsunami, proyeksi jumlah pengunjung untuk menunjang analisis. Titik evakuasi (TE)/titik aman dibutuhkan dalam proses evakuasi, maka analisis mengenai area evakuasi tersebut perlu dilakukan. Proses analisis dilakukan dengan terlebih dahulu menentukan ketinggian elevasi titik aman. Ketinggian elevasi titik aman dapat berupa titik yang berada di luar jangkauan gelombang tsunami ataupun area yang berada di dalam area genangan tsunami. Hasil penelitian ini adalah nilai ketinggian titik kumpul/titik aman 25 meter dari permukaan laut menjadi dasar untuk menyelamatkan diri, jika dihubungkan dengan kecepatan orang berjalan (kondisi lemah), maka waktu kedatangan/waktu tiba tsunami didapat tidak lebih dari 1 jam, hal ini masih dalam batasan sesuai dengan Federal Emergency Management Agency (FEMA P-646, 2008), lokasi titik kumpul/titik aman evakuasi tsunami tersebut bisa digunakan penyelamatan pertama korban tsunami dengan mempertimbangkan waktu kedatangan tsunami, sedangkan pada BPBD untuk penampungan korban tsunami menggunakan fasilitas umum walaupun jaraknya jauh dan mengindahkan waktu kedatangan tsunami.Kata kunci: elevasi, evakuasi, identifikasi, pantai, tsunamiABSTRACTThe maximum number of monthly visitors to the tourism coasts in Gunungkidul Regency between 2014 and 2017 is 18.369 people. Those Indian Ocean beaches that are in the southern sides of the Island of Java are prone to tsunami disaster. However, there were no systematic and scientific study to make analysis of the tsunami disaster mitigation to those tourism beaches. Therefore, a series of policies with comprehensive rescue strategies and efforts to minimize the risk of the tsunami disaster is required. The purpose of this study was to determine places of tsunami evacuation for the tourism beaches in Gunungkidul Regency based on P646 of FEMA (Federal Emergency Management Agency) and compare them with the result of the determine places of tsunami evacuation conducted by BPBD (Local Disaster Management Authority) of Gunungkidul Regency, Yogyakarta. This purpose also includes the want of the authors to implement the method of this study to be the policy of tsunami mitigation for similar tourism beaches in the Special Territory of Yogyakarta as well as similar beaches in Indonesia. This study uses quantitative method with descriptive analysis technique that is analyzing the paths and places of tsunami evacuation based on P646 of FEMA. Given location elevation is the basic ingredient of the analysis, and therefore, elevation data, tsunami arrival time, projected number of visitors to support the analysis need to be gathered. The analysis of the evacuation areas is required to determine the evacuation places that are safe points in the evacuation process. An elevation of a safe point elevation can be a point that is beyond the reach of tsunami waves or safe areas within the tsunami pool areas. The results of this study are the height of the gathering point / safe point 25 meters above sea level to be the basis for saving themselves, if connected with the speed of walking (weak condition), then the arrival time / arrival time of the tsunami is not more than 0.5 hours. This is still within limits in accordance with the Federal Emergency Management Agency (FEMA P-646, 2008), the location of the gathering point / tsunami evacuation safe point can be used as the first rescue of tsunami victims by considering the arrival time of the tsunami. On the other hand, BPBD accommodate tsunami victims using public facilities even though they are far away and heed the arrival time of the tsunami.Keywords: elevation, evacuation, identification, beach, tsunami
