Abstract

Estuari merupakasn bagan aliran muara sungai yang dipengaruhi oleh pasang surut air laut. Tidak sedikit estuari yang menjadi objek vital terutamadalam hal pengembangan ekonomi baik dalam skala lokal maupun internasional.Muara Krueng Langs merupakan Muara yang potensial, dengan letak geografisyang strategis menjadikannya sebagai alternatif dari pelabuhan Belawandalam perdagangan ekspor-impor barang. Perubahan iklim global dan eksplorasi yang tidak seimbangmenyebabkan banyaknya permasalahan pada komponen-komponen penyusunestuarinya seperti masalah banjir Rob, intrusi air asin dan sedimen. penelitian ini bertujuan untuk mengetahui keadaan komponen estuariseperti: bathimetri, arus, pasang surut, temperatur, salinitas dan sedimen di setiaptitik tinjauan Muara Krueng Langsa pada setiap jamnya. dari penelitian diperoleh hubungan antara bathimetri, pasang surut, arus,temperatur, salinitas dan kadar sedimen melayang dalam bentuk sebuahpemodelan. Didapat kesimpulan kenaikan pasang dan surut air laut mempengaruhikarakteristik Muara Krueng Langsa sejauh 16 km dari mulut muara. Kedalamanair yang dipengaruhi oleh komponen utama pasang surut matahari (S₂), bulan(M₂), dan pembangkit (M₄),estuari tiak hanya di pengarhi oleh air laut ada juga pengaruh debit air sungaisehinga terjadinya perpindahan molekul air baik dari hulu sungai menuju laut atau sebaliknya. Hal ini tentu membuat nilai dari temperatur, salinitasdan kadar sedimen mejadi tidak linear pada setiap titik dan jamnya. Dariperhitungan sedimen diperolehkadar sedimen maksimum sebesar 99,99 mg/dm³

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.

Abstract

Mushalla is a very important role in the development and teaching of islam, and one of the supporting facilities in the faculty environment as an increase in spiritual activities and to meet the needs of worship. Therefore, with the planning of this mushalla, it is hoped that it can improve the existing infrastructure in the Faculty of Engineering and produce high quality and highly competitive graduates, especially for graduates of the Civil Engineering Study Program at Samudra University. The purpose of planning this mushalla is; designing a mushalla building design with an architectural concept that is comfortable, effective and environmentally friendly or eco design, designing a mushalla building design that is open and blends with nature. Method of collecting data; field survey, location determination, and data processing. Data processing analysis; calculating the area requirements of the room, making alternative plans and visible designs of the mushalla building. The results of this study can be concluded that the land used has an area of 3.100 m². In planning this Mushalla, three design alternatives are planned, namely; The first alternative mushalla design has a total floor area of 2 floors and a floor area of 380 m² with a rectangular design concept, the second alternative mushalla design has 1 floor and a floor area of 228.16 m² with a pentagon design concept, then the third alternative mushalla design has The number of floors is 2 floors and the floor area is 661 m² with the concept of the Space Frame roof design.

Abstract

When designing a multi-storey building structure, the basic principle must be considered, namely increasing the structure's resistance to shear forces. Shear walls are one of the most common types of lateral load structures used to increase the rigidity of the structure and to absorb large shear forces as the structure increases. Previous studies have shown that shear walls will provide different performance depending on the location of the shear walls. This final project will examine the structure of flats with 5 variations of frame wall shear walls. The structure consists of 5 floors with a height of 17.6 meters and is located in the Langsa area. This research was conducted using ETABS V18 software. The results of the analysis show the value of the deviation of the 5 models. Based on the analysis of the calculations that have been carried out, it was found that the value of the deviation between floors in the 5th variation has fulfilled the permit deviation requirements based on SNI 1726:2019 for the x and y directions with the largest deviation value, namely on the 4th floor of 49.429 mm for the x direction and on the floor not of 27.935 mm for the y direction. Shear wall modeling is considered the most effective in the structure of this apartment building,namely in variation 5 it resists lateral forces such as earthquake loads and additional floors can be added using variation 5
