Abstract

Much of the kettle ash waste found in palm oil mills is wasted and can pollute the environment. Therefore, efforts need to be made to handle this waste. One of them is its use as an additional ingredient in concrete mixtures. . This research aims to analyze the effect of kettle ash on the rate of increase in compressive strength through laboratory testing with variations in kettle ash used, namely 0%, 5%, 10%, 15% and 20% of the cement weight. The test specimens have dimensions of 15 cm x 15 cm x 15 cm with testing times at 3 days, 7 days, 14 days, 28 days and 56 days. Based on analysis of research data, it was found that the majority experienced an increase in the compressive strength of concrete without additional materials. Increases occurred at 3 days, 7 days, 14 days and 28 days. The percentage increase in compressive strength for the majority decreased at the age of 3 days, 7 days, 14 days. Meanwhile, at the age of 56 days the majority experienced an increase in the percentage of compressive strength which was caused by a quite significant increase in compressive strength. The highest compressive strength at 56 days was produced by test object code BAK 1 of 38.59 MPa

Abstract

AbstrakPengujian termografi aktif merupakan salah satu pengujian non-destruktif yang menggunakan kamera inframerah sebagai perekam dan menghasilkan termogram. Termogram merupakan interpretasi energi panas yang diterima oleh sensor termal kamera inframerah yang masih mengandung noise. Reflected temperature (Trefl) merupakan salah satu noise yang muncul dari pengujian termografi aktif dan akan digunakan sebagai nilai koreksi. penelitian ini menyajikan suatu metode untuk mencari posisi pemasangan termokopel di sekitar sumber panas, sehingga nilai suhu pada posisi tersebut digunakan sebagai nilai Trefl untuk memperbaiki noise pada termogram. Sampel beton berbentuk kubus dengan ukuran 10x10x15 cm diukur suhu permukaannya menggunakan termokopel dan kamera inframerah sejauh 1 meter. Hasil penelitian menunjukkan selisih hasil pengukuran menggunakan termokopel dan termografi sebesar 2,349 ℃, lalu rata-rata nilai Trefl yang didapatkan dari pengujian termografi aktif sebesar 51,649℃ terletak 13 cm dari atas papan grid sebesar dan 5 cm di depan lampu halogen. Suhu permukaan beton sebelum dikoreksi memiliki nilai yang lebih tinggi karena memiliki noise, namun setelah dilakukan analisis perhitungan suhu mengalami penurunan dan mendekati suhu hasil pengukuran termokopel dengan analisis kesalahan (ΔTerr) rata-rata didapatkan 1,448%. Berdasarkan hasil analisis terebut menunjukkan akurasi data kesalahan tergolong bagus karena nilai rata-rata analisis kesalahan (ΔTerr) <5%.Kata kunci : Reflected Temperature, Termografi aktif, Pengujian Non-destruktif

Abstract

Earthquake resistant buildings are not designed only by strengthening the resistance of the structure, but are also designed to reduce earthquake forces. One of the structural reinforcement elements that can reduce earthquake forces is shearwall. The variation of shearwall layout will have a different effect on the performance level of the structure. This study aims to determine the performance level of the structure with a variety of shearwall layouts in a building structure model using the pushover analysis method. Determining the level of structural performance using pushover analysis is carried out using the help of structural analysis programs based on SNI 1726-2019, SNI 1727-2020, SNI 2847-2019 and ATC-40. From the research results it was found that the structural performance level according to ATC-40 (1996), for model 1 and model 6 were included in the damage control category, while for model 2, model 3, model 4 and model 5 were included in the immediate occupancy category. Placement of shearwall which has the optimum value according to ATC-40 for the X direction occurs in model 2 with the shearwall installed in an L shape which is placed near the center of mass of the building. Whereas in the Y direction it occurs in model 3 with the shearwall installed in an L shape which is placed away from the center of mass of the building. Key words : shearwall, model, structure performance level, pushover analysis.

Abstract

Indonesia is a region that is at risk of earthquakes. The impact of an earthquake is bad for the building structure, not only causing damage to the building, but also can cause the building to collapse. Therefore, to reduce the adverse effects obtained from earthquakes, it is necessary to design and evaluate the strength of building structures with resistance to earthquake loads. The method used in this study is dynamic response spectrum analysis to obtain the magnitude of the earthquake load. Evaluation of the strength of the building structure is carried out using structural analysis software to make it easier to do the analysis. This study aims to determine the ratio of the required strength in conditions without earthquake loads and conditions due to earthquake loads to the designed strength of the structure. Based on the results of this study, it can be concluded that the required strength obtained in conditions without an earthquake load reaches 8.33% to 90.62% of the designed strength, whereas in conditions due to strong earthquake loads the required strength obtained reaches 12.57% to 153.31% of the designed strength.Keywords: earthquakes, structural strength, dynamic analysis, response spectrum.

Abstract

SCC is fresh concrete that is able to flow through the reinforcement and fill the entire space in the mold without requiring manual compaction or mechanical vibration. SCC has a shortage of weak tensile strength values as in other concrete. So an innovation was made, namely the addition of fiber to the concrete. In this study, using a combination of bendrat wire and 3D Dramix with a length of 6 cm and a diameter of 0.8 mm, the volume fraction of the mixture amounted to 1% and 1.5% with a total of 8 combinations.  The compressive strength test object was a cylinder with a diameter of 150 mm and a height of 300 mm totaling 24 pieces and the flexural tensile strength test was a beam with a length of 400 mm, a width of 100 mm, and a height of 100 mm totaling 24 pieces. Tests were conducted at the age of 28 days. From the test results, the highest compressive strength occurred in BSV, namely a combination of 1.25% bendrat wire and 0.25% 3D Dramix with an increase in compressive strength of 15.04% of normal concrete. In the flexural tensile strength test, the maximum increase was obtained in BSV, namely the combination of 1.25% bendrat wire and 0.25% 3D Dramix with a percentage increase of 1206.5% from normal concrete.  This shows that the addition of 3D Dramix and bendrat wire increases the compressive strength and flexural strength of SCC. However, the more fiber in SCC causes the workability of the concrete to decrease and the pores in the concrete to increase.
