چکیده

Jembatan Loa Haur merupakan sebuah jembatan tipe rangka baja dengan bentang 60 meter dibangun pada tahun 1992 yang terletak Jalan Poros Samarinda – Tenggarong, Desa Bakungan, Kecamatan Janan Kutai Kartanegara Kalimantan Timur. Akibat kondisi lalu lintas dan beban kendaraan melintas semakin meningkat di Haur, untuk keamanan kenyamanan pengguna, perlukan evaluasi struktur jembatannya. Salah satu bagian akan dievaluasi penelitian ini yakni mutu beton terpasang saat terhadap standar spesifikasi Bina Marga khususnya sisa kekuatan tekan batas minimal 250 Kg/cm2, atau 20 MPa. Pengujian mengambil metode non destructive menggunakan alat Hammer test Ultrasonic Pulse Velocity Test. diawali rebar locator bertujuan mendeteksi diameter posisi tulangan dalam elemen beton, serta ketebalan selimut memanfaatkan medan elektromagnetik, mudah terpengaruh oleh adanya logam/metal berupa karena Test sangat terganggu bila melewati tulangan. Dilanjutkan pengujian sebanyak 120 titik abutmentt 63 Pelat lantai. Untuk UPV Tidak Langsung sampel 49 plat lantai jembatan. Hasil analisis diperoleh nilai abutment pelat masih memenuhi yaitu sebesar 479 kg/cm2 454 , sedangkan hasil uji juga 265 243 kg/cm2.

Detection of Concrete Damage Using Ultrasonic Pulse Velocity Method

This paper investigates the efficiency of Ultrasonic Pulse Velocity (UPV) method in detecting cracks and flaws inside the concrete. A series of concrete beams and slab specimens were cast and damaged to simulate the different mechanisms possible in a reinforced concrete deck due to mechanical loading. Two types of simulated cracks, namely, cracks perpendicular and cracks parallel to axis of bea...

Wind-Electric Power Potential Assessment for Three Locations in East Java-Indonesia

This paper reports our effort to asses wind energy potentials for three locations in East Java. We used wind speed data over a period of almost 3 years, i.e. in period of June 2006 – August 2008. Data were taken from direct measurement in locations in East Java Province, i.e. Sampang (Madura), Juanda (Surabaya), and Sawahan (Nganjuk). The short-term of wind speed mean in monthly signifies to wi...
