Abstract

The useful life of reinforced concrete structural elements could mean that the structural elements of reinforced concrete is not able to withstand the repeated load. In this regard, conducted research that aims to understand the behavior of reinforced concrete flexural loading fatigue and effects receives tired and reinforcements Sheet Glass Fiber Reinforced Polymer (GFRP-S). Methods to set boundaries or controls in the calculation of the capacity of the test beam and its impact on behavior and reinforcement in the beam test obtained in a number of references. This study makes a test beam with a full-scale model with a size of 300 x 500 x 6000 mm. Number of test blocks are provided each with 4 pieces of reinforced concrete. Tests conducted on the technique of static loading on 3 pieces of test beams A 1, B 1 and B 2 and the fatigue loading on the first specimens of B 2 with 1:25 Hz cycle frequency. The results showed that the effect of fatigue on concrete receiving sufficient load capacity and a big influence on the behavior of concrete. Concrete receiving static load is able to accept a maximum load of 470 kN while the concrete receiving the fatigue load is able to accept the fatigue load minimum 75 kN and 260 kN maximum endures to 1,300,000 cycles with a greater deflection behavior. Observations on the beam construction of static and fatigue loading test showed retrofitting of GFRP-S is able to increase the capacity of the test beam in the receiving load. Capacity test on the beam reinforcement GFRP has not mencapai ultimate theoretical capacity, so it needs further study regarding pengaruh cracking and melting before retrofitting GFRP rebars. Analysis of fatigue in structures is essential for the achievement of the design life of the structure and the salvation of mankind

Abstract

Batubara merupakan bahan bakar fosil yang dapat dijadikan sebagai sumber bahan bakar alternatif pengganti bahan bakar minyak bumi dan gas alam yang sudah semakin menipis. Cadangan batubara di Indonesia, khususnya di Sulawesi cukup berpotensi, namun hingga saat ini belum dapat dimanfaatkan sebagai bahan bakar mengingat kandungan sulfurnya relatif tinggi yang dapat menyebabkan kerusakan pada alat pembakaran, dan dapat menimbulkan pencemaran lingkungan, kecuali terlebih dahulu dilakukan proses desulfurisasi sebelum pembakaran (precombustion). Penelitian ini bertujuan untuk mereduksi kandungan sulfur pirit dalam batubara sehingga memenuhi kriteria untuk dimanfaatkan sebagai salah satu bahan bakar industry. Secara khusus penelitian ini bertujuan untuk mempelajari mekanisme dan kinetika depiritsasi batubara menggunakan oksidator feri sulfat, sebagai usaha meminimalisasi kandungan sulfur batubara tersebut, maka dilakukan penelitian Desulfurisasi Batubara Menggunakan Oksidator Besi (III) Hasil Olahan Limbah Besi. Penelitian desulfurisasi batubara asal Mallawa (Sulawesi) skala laboratorium dilakukan dalam sebuah reaktor (labu leher empat) dengan sistem semi batch, dilengkapi dengan sebuah kompressor, flowmeter, termometer dan pengaduk. Karakterisasi, analisis proximate dan ultimate batubara dilakukan mengikuti prosedur ASTM Standar. Analisis sulfur total dilakukan dengan metode esckha yang dikombinasi dengan spektrofotometer UV, sedangkan nilai kalor batubara diukur dengan alat bomb kalorimeter. Dari hasil per hitungan diperoleh nilai orde reaksi n = 1,771. Nilai ini ternyata tidak bulat tetapi pecahan yang menunjukkan bahwa reaksi depiritisasi dengan pereaksi besi (III) sulfat merupakan reaksi kompleks yang terdiri dari beberapa tahap reaksi. Hasil penelitian ini diperoleh persamaan kinetika depiritisasi batubara dengan pereaksi besi (III) sulfat pada suhu 90 oC, kecepatan pengadukan 930 rpm sebagai berikut : – rS = 6,741.10-2.CS(1,771)
