Abstract

Balok beton bertulang sebagai elemen struktur yang berfungsi menahan lentur dan geser dimana parameter utama untuk menentukan kuat lentur dan geser balok beton bertulang meliputi: dimensi penampang, mutu beton, mutu baja tulangan, ukuran baja tulangan dan jumlah baja tulangan yang digunakan. Dalam konstruksi parameter tersebut umumnya memiliki batasan minimum, seperti halnya dengan jarak tulangan dan dimensi penampang kecil. Untuk mendapatkan elemen struktur dengan penampang kecil namun memiliki kekuatan yang besar, dengan jarak tulangan yang kecil karena luas tulangan yang dibutuhkan besar, maka perlu dilakukan penempatan tulangan dengan cara bundel. Tujuan penelitian ini untuk mengetahui nilai kuat lentur dan geser balok beton tulangan bundel TP 4Φ6 dan balok beton tulangan tunggal Φ12 yang memiliki proporsi luas penampang tulangan yang sama. Analisis dilakukan dengan metode analisis teoritis dengan data yang diperoleh dari hasil eksperimen terdahulu. Berdasarkan hasil analisis diperoleh nilai kuat lentur rata-rata balok tulangan bundel TP 4Φ6 = 8,53 kN.m, dan balok tulangan tunggal Φ12 = 11,31 kN.m. Nilai kuat geser rata-rata balok tulangan bundel TP 4Φ6 = 58,88 kN, dan balok tulangan tunggal Φ12 = 57,92 kN. Dari hasil eksperimen dan analisis diperoleh perbedaan kuat lentur balok tulangan bundel TP 4Φ6 sebesar (6,36%) dan balok tulangan tunggal Φ12 sebesar (48,62%). Sedangkan kuat geser balok tulangan bundel TP 4Φ6 diperoleh hasil yang sama yaitu 58,88 kN dan balok tulangan tunggal Φ12 diperoleh perbedaan sebesar (0,03%).

Abstract

Landslides are a disaster that often occurs in Ciherang Village. The high intensity of rainfall causes unstable slopes resulting in landslides in the Bandung-Garut highway area, Ciherang Village, Nagreg District, Bandung Regency. This area is a mountainous area which has medium to high potential for ground movement to occur. The aim of this research is to determine the stability of slopes using retaining wall reinforcement. Building a retaining wall in the Ciherang village area. One of its functions is to stabilize the land area around the road shoulder so that landslides or land subsidence do not occur due to natural factors (rain or flood) or the pressure factors of the loads acting on it. The method used is a quantitative descriptive method. Descriptive approach with observational data collection techniques in the field for measuring, observing and taking soil samples. A retaining wall is a structure built to support the surface of a slope. Permanent walls are used to withstand lateral pressure from unstable soil due to soil erosion or topographic conditions to overcome soil erosion problems and reduce the risk of road damage. Calculation of soil stress using the Rankine method and stability against failure of soil bearing capacity based on the Terzaghi equation based on characteristic parameters (c and Ø). The results of the calculation of the cantilever type retaining wall using soil data from laboratory tests with a retaining wall height of 8 m, base width (L) of 4.80 m, obtained a safety factor against overturning force of 3.2 and a safety factor for shear force of 1.73 . Both safety factors meet the minimum requirement of 1.20.

Abstract

Building structures must be in good condition and meet technical feasibility criteria. Ziadat-ul-Abror Floating Mosque on Pagatan Beach, Tanah Bumbu Regency, South Kalimantan, which was initiated and built by PT. It is hoped that Borneo Indobara will become an attraction for religious tourism in Tanah Bumbu. Apart from the security aspect, the comfort aspect for users must be a concern. Inspection of compliance with vibration standards is one of the parts that must be carried out to ensure that worshipers feel safe and comfortable when worshiping in the mosque. This is in line with what was decided in the Decree of the Minister of the Environment No. 49 of 1996 and regulated by ISO 2631-2 1989 which requires vibrations that do not damage buildings, disturb human comfort and health. From the results of the vibration test it is known that vibration in operational conditions is still within the permissible limits with a frequency between 5.66-15.86 Hz, peak vibration acceleration 0.36-1.94 %g, peak vibration velocity 0.10-1.99 mm/ det and dynamic deflection 1.22-67.37 mm.
