Abstract

In terms of structural design of reinforced concrete buildings for earthquake-resistant, the beamcolumn joint is a critical area that needs to be accurately designed properly so that the area is able to dissipate energy in the event of an earthquake. The ability of beam-column joint to deform in the inelastic region provides a structure that has a good ductility, so as to minimize the damage caused by earthquake shaking. This study aims to analyze the design of beam-column connection at the Parliament Building-City Hall of Jakarta. The analysis performed refers to the ”Tata Cara Perhitungan Struktur Beton Untuk Bangunan Gedung”, SNI 03-2847-2002. The analysis results shows that the terms of detailing in the field implementation have not been fulfilled properly.

Abstract

Bono tidal current leads to silting of the river estuary. The impact is a change in river line of Muda Island due to erosion and deposition. One alternative construction to overcome such this erosion problem of isGeotube, a construction system that combines geosynthetic material for blanket and sand slurry material for filler. Analysis is performed to ensure the system is feasible through the use of Geocops software to determine the type of suitable geosynthetic material and other parameters such as pump pressure. Another analytical calculation performed is the calculation of the stability of global construction through the use of Slope/W software and the approximate amount of consolidation decrease occurred using one-dimensional consolidation theory, published by Terzaghi. This article also presents the process of field implementation including various obstacles encountered and the solutions. From the results of the analysis and the field implementation, it can be concluded that the use of Geotube system on this project provides satisfactory results and can be relied upon as an alternative construction of erosion problems.

Abstract

Decision making is a process of choosing an alternative action used for a specific purpose or goal that has been set. Managerial decision-making involves data and information from entire business process. Data and information are procesesed to support decision-making. The purpose of this paper is to get a statement of goals, problems and data of the UKM Gerak Tani. The Method to be used is inteliggence phase which is the first stage of the four stages of decision making according to Herbert A Simon. It includes several activities aimed to identify problem situations or opportunities such as finding the problem classification, problem decompositionand problem ownership. The expected results of this research are the purpose documentation of the organization, searching and scanning procedures, data collection, identification of issues, ownership issues, classification issues and problem statement.
