Abstract

Kebutuhan beton mutu tinggi sangat dibutuhkan pada saat ini, terbukti dari pembangunan gedung-gedung berlantai banyak serta gedung dengan massa bangunan yang besar. Bersinergi akan hal tesebut, pekembangan dari teknologi beton mutu tinggi pu sangat di butuhkan. Material penyusun beton mutu tinggi seperti semen, agregat halus, agregat kasar serta air yang merupakan material-material pilihan. Tetapi, penggunaan material agregat kasa dan halus yang diambil secara tidak terkontrol dapat menyebabkan kerusakan alam, khususnya daerah aliran sungai. Menjawab tantangan tersebut, maka dibuat penelitian yang menggunakan material alternatif untuk menggantikan material agregat. Pasir pozzolan yang banyak mengandung silika digunakan untuk menggantikan agregat halus pada pembuatan beton mutu tinggi. Penelitian dilakukan dengan menggatikan agregat halus dengan menggunakan pasir pozzolan, dengan komposisi 10%, 20%, 30%, 40% dan 50% dari total berat agregat. Campuran beton direncakan dapat menahan beban sampai 70 MPa dengan rincian pemakaian seperti berikut; semen sebanyak 600 kg/m3; Superplasticizer yang digunakan adalaah viscocrete 10. Dari hasil penelitian didapat bahwa pemakaian substitusi pasir pozzolan sebagai agregat halus sebanyak 10% meningkatkan nilai kuat tekan beton mutu tinggi.

Abstract

The completeness of the Gampong administration is something that must be done to achieve administrative order. The community service activities carried out in Gampong Sembuang which is located in the Lokop sub-district of East Aceh district aim to obtain the Gampong Sembuang Mosque Design, the Keuchik Office Design, and the Gampong Sembuang Map. The method used for the design activities of the Gampong Semburan Mosque and the Keuchik Office Design was to go directly to the field to obtain exact land size and shape data, while for Village Mapping activities the assistance was assisted using the Google Earth application and the student version of ArcGIS. The results of the community service activities were in the form of a poster of the Village Map, the design of the Gampong Mosque, and the Office of the Gampong Keuchik which were handed over to the Keuchik of Sembuang Gampong.

Abstract

The addition of a floor is an alternative to a building and a development due to an increase in the function of the shophouse or an additional infrastructure but the available land is limited. In this study, an analysis of the structure of the existing building was carried out to determine the influence and capability of the structure when adding floors to the building. If the building structure is not able to withstand the loads that work due to the addition of floors, then elements that are not strong in the existing structure are required to strengthen the structure, strengthening with the concrete jacketing method. Analysis of the structure of the planned addition of floors by adding 1 floor so that it becomes 3 floors and then 3D modeling using the SAP2000 program. Building plan with a size of 16 mx 28 m, height 4 m on each floor, concrete quality (f'c) 30 MPa, yield stress (fy) 240 MPa for reinforcement diameter ≤ 10 mm, yield stress (fy) 400 MPa for reinforcement diameter > 10mm. The addition of the building floor to the structural elements and the loading is the same as the existing structure, the analysis of the earthquake with equivalent static and earthquake load analysis based on SNI. The result of structural analysis is the ability of the initial structure due to the addition of the floor. Reinforcement of structural elements with concrete jacketing, enlargement of dimensions and addition of reinforcement for beams and columns. Enlargement of beam dimensions 30/40 to beam 50/60, column 30/40 to 50/60. The addition of reinforcement was carried out because the calculation did not meet the requirements, 10 Ø 16 was added to the beam bearing area, 8 Ø 16 of the reinforcement field was added to the beam, while 14 Ø 16 was added to the column.
