Abstract

Indonesia is an area with a high level of vulnerability to earthquake disasters, where this earthquake has caused a lot of losses and damage to building structures. Therefore, to reduce the risk due to the earthquake, it is necessary to plan earthquake-resistant building structures. The structural planning of building construction is needed to get the most effective and efficient dimensions and configuration of the structure. Collapsed buildings that are not strong enough to withstand lateral loads caused by the earthquake have resulted in significant loss of property and even lives. The purpose of writing this thesis is to design an earthquake-resistant Mardhika Park Apartment Building with a moment-resisting frame system (SRPM) which is planned in accordance with SNI 1726:2019 Earthquake (Earthquake Resistance Planning Procedures for Building and Non-Building Structures), SNI 2847 for Reinforced Concrete: 2019 (Requirements for structural concrete for buildings and their explanations), and the loading in accordance with SNI 1727:2020 for (Minimum Loads for Design of Buildings and Other Structures). The structural design of the Mardhika Park Apartment Building includes the design of this superstructure which includes columns, beams, and floor plates. Then the loads that are reviewed for structural element planning are dead, live, and earthquake loads. To assist in calculating the structure is also used Software "SAP2000 " to facilitate the calculation of the structure.

Abstract

Cement injection under pressure, also known as grouting, is a process in which a liquid mixture is injected into cavities, cracks, and fractures in rock or soil under controlled pressure. The injected liquid undergoes physical and chemical transformations, eventually solidifying. This study aimed to evaluate the performance of various cement-water mixture designs, determine the required volume of grout based on the Lugeon number (Lv), and assess effective spacing intervals between grouting points by calculating grout effectiveness in percentages. Jet grouting, a proven method in diverse soil conditions, employs specialized equipment to hydraulically mix soil with grout, enabling soil stabilization and modification. The system is particularly effective in erodible soils, such as granular soils, and even in cohesive plastic clays. At the Mila Dam, grouting tests were conducted along the centerline of the main dam, specifically at the left abutment (Bukit Tumpuan Kiri) and the riverbed. Core drilling results from the Pilot Hole (BH-01) at a depth of 30 m revealed stratigraphic characteristics. The left abutment rock along the centerline of the dam predominantly consists of gray lapilli tuff overlaid by breccia-tuff rock units, which are brownish in color.
