Abstract

Intake structures are facilities for clean water supply situated along riverbanks. These structures are reinforced concrete with pile foundations, and the intake structure comprises a profiled steel frame serving as the upper column-beam framework. The implementation of steel structures demands a high level of precision, particularly in designing connections between sectional steel beams and columns. This study, therefore, aims to determine the optimal dimensions for steel profiles by referring to the design of bolt connections as specified in SNI 1729-2020, particularly for steel beam columns subjected to pump loads and load combinations. The analysis concludes that all three material types meet the safety criteria, with a structural ratio value of ≤ 1 and structural deflection within the allowable limits. Additionally, after assessing the steel column and beam sections' capacity to bear pump loads, it was determined that the optimal bolt connection involved 8 bolts of 24 mm diameter. The ideal supplementary steel plate connection required a plate thickness of 13 mm.

Abstract

Jambi City IPAL is a new construction which is a container for processing Jambi City's domestic waste. The source of the sludge comes from household wastewater in Jambi City. The sludge produced from the Jambi city wastewater treatment process (IPAL) is dark brown in color and the sludge is floc in nature. District is mud whose grains are separated without coagulants, generally this mud contains sand, grit and small gravel fragments. Mud in the form of floc, namely (chemiflocc) is very large in volume, especially in WWTPs. The XRF results of WWTP mud show high levels of SiO2 and Al2O3, namely 61.56% and 26.93% respectively. The elements contained in cement are found in WWTP mud such as SiO2, Al2O3, Fe, CaO, K2O, MgO, and Na2O. If compared, WWTP mud has the same properties as cement. XRD test results show  crystal phase conditions show peaks with the highest count value at the position [o2Theta] 26.701OH. The SEM mud results show that the grains are in the form of fragments like irregular lumps with varying grain sizes. This condition shows that dry mud has good binding capacity. Jambi City WWTP waste sludge from XRF results has a mineralogical composition similar to cement, because it contains main oxides such as SiO2, Al2O3, CaO, and Fe. Based on its chemical composition, waste sludge has the potential to be used in the production of construction materials after being subjected to combustion treatment.

Abstract

Cold formed steel (CFS) sendiri memiliki dasar pelat yang sangat tipis sehingga cepat untuk mengalami tekuk pada awal deformasi. Mudahnya kondisi CFS megalami kegagalan tekuk, maka peneltian CFS sangat memperhatikan dalam desainnya terhadap sambungan balok ke kolom. Desain sambungan tersebut ditujukan pada komponen sambungan seperti baut dan pelat penyambung seperti rectangular gusset plate, T gusset plate, seat angle, web angle, dan haunched gusset plate. Sambungan ini tidak memerlukan pengelasan dan hanya memerlukan instalasi sederhana. Beberapa tahun belakangan ini pengembangan penelitian terhadap gusset plate sudah semakin dikembangkan terutama tipe haunched gusset plate (HGP). Dalam paper ini akan disajikan metode analisis menggunakan Finite Element Method (FEM) terhadap sambungan HGP dengan tebal pelat 10 mm, baut diameter 12 mm, serta balok dan kolom berukuran C30024. Prangkat lunak yang digunakan untuk membantu dalam menganalisis FEM yaitu ANSYS WORKBENCH. Beberapa metode yang akan dilakukan yaitu menentukan material data, permodelan sambungan, meshing, penentuan kontak analisis, dan melakukan solve analysis. Setelah metode dilakukan maka keluar output berupa nilai defleksi, momen, dan rotasi serta kontru deformasi dan tegangan pada struktur sambungan. Deformasi maksimum yang terjadi yaitu sebesar 29,5 mm. Kesimpulan akhir yaitu perbandingan antara hasil FEM dengan hasil  eksperimen dengan telah dilakukan oleh peneliti sebelumnya.Perbandingan nilai momen rotasi tersebut berkisar 28,89%.
