Abstract

The sluice gate is a measuring structure that controls the upstream discharge and water level. The varying height of the sluice gate opening will cause the water level to vary both upstream and downstream. The difference in water level upstream and downstream can potentially cause scouring downstream of the gate. This study aimed to determine the effect of the height of the sluice gate opening on the flow characteristics. This study used a research method in the form of a physical model on an open channel (flume) at the Integrated Laboratory of Sultan Ageng Tirtayasa University Sindangsari. The stages of this research included pitot pipe calibration and research of flow characteristics on the height of the gate opening with variations in the height of the sluice opening (9, 10, 11, 12, 13 cm). The sluice model used is made of wooden boards with the dimensions of the door width being 1/3 of the width of the channel. The results showed that the higher the sluice opening (a), the lower the upstream water level (H) and the greater the downstream water level (Y). While the upstream flow velocity (V0) was greater and the downstream flow velocity (V1) was getting smaller so were the upstream Froude numbers (Frupstream) and downstream Froude numbers (Frdownstream). The upstream flow is classified as sub-critical flow (Fr<1), while the downstream flow is classified as super-critical flow (Fr>1).

Abstract

Penggunaan beton sebagai salah satu bahan konstruksi bangunan kini sudah dikenal luas. Beton mempunyai keunggulan kuat tekan yang tinggi serta mempunyai sifat tahan terhadap korosi atau serangan kondisi sekitar. Beton merupakan suatu material yang terdiri dari campuran semen, agregat halus, agregat kasar, dan air. Agregat merupakan butiran mineral yang berfungsi sebagai bahan pengisi pada campuran beton. Cangkang kerang  merupakan salah satu jenis limbah yang digunakan sebagai pengganti agregat halus karena dapat  digunakan untuk meningkatkan kuat tekan beton. Sika Viscocrete 3115 N meningkatkan sifat beton, seperti kekuatan dan daya tahan serta mengurangi  penggunaan air. Penelitian ini menganalisis pengaruh penggunaan kerang serbuk cangkang sebagai substitusi agregat halus sebesar 5%, 10% ,  dan 15% , serta menggunakan  Sika Viscocrete 3115 N sebagai bahan tambahan semen sebesar 0,8%. Perbandingan dilakukan antara beton normal plus campuran, beton SP ,  dan beton variasi serbuk cangkang kerang. Berdasarkan hasil uji kuat tekan menunjukkan beton normal umur 28 hari sebesar 25,39 MPa, beton SP 0,8% umur 28 hari sebesar 25,85 MPa, sedangkan beton substitusi agregat halus berupa turtle cangkang 5% pada umur beton 28 hari sebesar 26,12 MPa, substitusi 10% sebesar 31,75 MPa dan substitusi 15% sebesar 35,45 MPa. Penggunaan SP 0,8% efektif meningkatkan  kuat tekan beton dari beton normal , sedangkan semakin tinggi penggunaan serbuk cangkang kerang sebagai pengganti agregat halus maka nilai kuat tekannya juga semakin tinggi. Hal ini dikarenakan  serbuk cangkang kerang mempunyai sifat rekat jika dicampur dengan air pada campuran beton serta mempunyai kandungan mineral yang mirip dengan semen.

Abstract

In some building designs that carry a high aesthetic or architectural value, the use of flat columns brings a number of significant advantages. Their slender design provides more flexibility in interior layout and adds to the aesthetic value of the building. This study was conducted to determine the reinforcement requirements and behavior of flat columns as well as checking the displacement in accordance with SNI 1726:2019. The results show that column I and column L are categorized as swaying and long columns, while column T and column Plus are included in the category of non-swaying and short columns. The required reinforcement requirements are as follows: For column I with dimension 130 x 800, 10D16 main reinforcement is required with D10-100 mm stirrups inside the plastic joint area and D10-150 mm outside the plastic joint area. Column L of dimension 130 x 500 requires 16D16 main reinforcement with D10-100 mm stirrups both inside and outside the plastic joint area. T columns of dimension 130 x 500 require 10D16 main reinforcement with D10-100 mm stirrups inside and outside the plastic joint area. Plus columns of dimension 130 x 400 require 12D16 main reinforcement with D10-100 mm stirrups inside and outside the plastic joint area. The maximum defelction that occurs is still within the permissible tolerance limits of 15.32 mm in the X direction and 11.15 mm in the Y direction so that the building structure is declared safe and stable against the loads received in accordance with SNI 1726: 2019.

Abstract

Efficiency in structural design is important to optimize the use of materials and costs, while maintaining strength and stability to ensure the safety of the building. With construction design regulations constantly updated, careful and precise planning calculations are crucial. This study identifies overdesign in columns, beams, and foundations of existing buildings, and aims to determine more optimal and efficient dimensions and repetitions, resulting in stronger, more economical, and standard-compliant buildings. The research was conducted in a 4-storey office building with dimensions of 32 x 15,725 meters will be analyzed based on SNI 2847:2019, SNI 1726:2019, and SNI 1727:2020. The analysis was carried out using Microsoft Excel and ETABS. The results of the study showed that there was overdesign in the main column, main beam, and foundation. On a beam of 400mm x 650mm it produces an efficiency of 17.46%. The bending reinforcement requirement results in an efficiency of 21.785%. Meanwhile, the shear reinforcement and middle reinforcement are the same as the initial planning. In a 450mm x 700mm column it produces an efficiency of 16%. For shear reinforcement, an efficiency of 10% is obtained. As for the bending reinforcement, it is the same as the initial planning. In the foundation design, 4 square piles with dimensions of 450mm x 450mm and pilecap dimensions of 2600mm x 2600mm x 500mm with reinforcement requirements for the x direction D22-100 and the y direction D22-125. Resulting in a pilecap volume efficiency of 28.888%.
