Abstract

PLTU Tidore adalah pembangkit listrik yang berbahan bakar batu bara berkalori rendah untuk melayani kebutuhan listrik masyarakat khususnya di Kota Ternate dan Tidore. Dampak penggunaan batu bara menghasilkan limbah berupa fly ash dan bottom ash. Pada penelitian ini dicoba untuk menggunakan bahan bottom ash sebagai bahan pengganti parsial terhadap agregat pasir pada pembuatan paving block dan meneliti klas mutu yang dihasilkan. Berdasarkan hasil pengujian sifat fisik bahan bottom ash memiliki karakter yang lebih ringan dari pasir dan tingkat penyerapan diatas 20% yang 10 kali lebih banyak dari standar bahan untuk agregat normal. Sementara senyawa kimia dominan penyusun bottom ash memiliki kemiripan komposisi dengan bahan pasir dan juga bahan semen sehingga bahan bottom ash tidak memberikan pengaruh buruk terhadap reaksi semen saat pengadukan. Hasil pengujian kuat tekan sampel mortar paving block dengan variasi pengempaan 10 kN dan 40 kN diperoleh laju penurunan kemampuan tekan mortar berkisar antara 0,8 MPa hingga 5,3 MPa dengan nilai rata-rata sebesar 2,1 MPa setiap penggantian 10% bahan pasir dengan bottom ash. Begitu pula dengan tingkat penyerapan paving block yang dihasilkan mengalami peningkatan seiring dengan penambahan jumlah bottom ash pada pembuatan paving block. Akan tetapi meskipun dengan penggunaan bahan bottom ash pada pembuatan paving block menybabkan degradasi kemampuan tekan dan peningkatan peyerapan, paving block yang dihasilkan masih lebih dominan pada klas mutu B dan pengempaan dengan gaya yang lebih besar akan membuat massa paving block lebih padat lagi.

Abstract

The design of a building requires various stages of calculation that consider many aspects so that the results that are in accordance with its functions are not only seen from structural aspects but also economic and aesthetic aspects are also taken into consideration. In building planning, the aesthetic and architectural development in it often leads to irregular / asymmetrical forms of buildings which then cause problems with building seismic irregularities.The building of the Universitas Khairun Postgraduate must be a strong, sturdy educational building and has an attractive and formal architectural appearance. Therefore researchers are interested in examining the structure of the building.The approach in this study is to use a qualitative and quantitative research approach. both approaches are used together or combined, where the approach is used interchangeably. In the first stage using a qualitative approach, so that the architectural concept of building Postgraduate was found. Furthermore, the structure of the building was tested by quantitative methods using the Sap 2000 program.The purpose of this study is to compile the analysis of structural and architectural concepts in the Building of the Universitas Khairun Postgraduate. The building of the Universitas Khairun Postgraduate must be a strong, sturdy educational building and has an attractive and formal architectural appearance.Angus J. Macdonald (2001).

Abstract

Pumice sand is a bright colored butian type, containing foam made from glass-walled bubbles andusually referred to as silicate volcanic glass granules. This pumice sand can be used as a substitutefor normal sand as fine aggregate in a mixture of concrete mix. Based on the characteristic testexamination, it can be seen that in testing the characteristics of pumice sand to the specificationsof normal sand in specific gravity testing and weight testing of quicksand obtained results thatare smaller than the specifications of normal sand and absorption tests obtained results greaterthan specifications on normal sand. The results of the normal sand compressive strength at BN is250.95 kg /cm2 while the results of the floating sand concrete compressive strength on BPA is224, 965 kg /cm2. Based on the research it can be concluded that with the same quality of concrete,the quality of K-250 is different in comparison to the compressive strength of concrete in normalsand and pumice sand concrete shows almost the same results. Therefore, more in-depth researchis needed regarding the use of pumice sand instead of normal sand in a mixture of concrete mix.

Abstract

This study aims to analyze the shear strength of layered reinforced concrete beams as a composite. Concrete beams consist of normal concrete f'c 25 MPa on the compression side and lightweight concrete of 2.55 MPa, 1.32 MPa and 0.31 MPa on the tensile side as a consequence of the use of styrofoam as much as 30%, 40% and 50% of the concrete volume. This layered concrete beam is intended to reduce the weight of the structure. The tested beam is designed without shear reinforcement with dimensions of .150 cm long, 15 cm wide and 32 cm high, given 3Æ12 flexural reinforcement. The beam test used two concentrated loads with an effective shear-span ratio (a/d) 1.43 to ensure shear failure. The shear strength of layered concrete beams depends on the quality of each layer of concrete where the higher the quality of the cross-sectional concrete, the higher the shear strength. The prediction of shear strength based on the regulation is in line with the shear strength in the first oblique crack condition.
