Abstract

In formulating the seismic design criteria for a building at ground level or determining the amplification of the peak earthquake acceleration from the bedrock to the ground for a site, the site must be classified first. Site class assignment must be carried out through field and laboratory soil investigations. Site Class consists of SA (hard rock), SB (rock), SC (medium soil), SE (soft soil) and SF (special soil). SNI 1726: 2019 with various classes of SB, SC, SD and SE sites. From the analysis results, it is found that the variation of soil site classes has an effect on the area of minimum reinforcement requirements, except for the logitudinal reinforcement requirements of the lower support beam for site class variations, the value is fixed. The variation of soil site classes has a significant effect on the area requirements of the longitudinal reinforcement in the column. The largest requirement for column longitudinal reinforcement is Soft Soil Site Class (E) and the smallest requirement is Rock Site Class (B).

Abstract

Accessibility related to public transport is a means of advancing the economic welfare of the community, creating and increasing economic degrees, as well as a precursor sector of other sectors. Therefore, people with disabilities are also entitled to the same service to the public transportation as an effort to realize similarities, the equality of citizens and the enhancement of the role of disability. This research aims to analyse disability access and the role of the transportation service of Semarang and PT. Trans Semarang on Bus Rapid Transit in Semarang City. This research uses a type of qualitative approach that is implemented through interviews, observations and documentation. The conclusion of this research shows that from the regulatory aspects, the government of Semarang should be appreciated because the government of Semarang has tried to fulfill the rights of the disabled. But from the implementation aspect, there needs to be an improvement because the accessibility of disabled people running optimally can be seen through the condition of public facilities in the city of Semarang. Public facilities in the city of Semarang do not completely ignore the reference accessibility means there are public facilities that have been good enough but many more are not optimal.

Abstract

Project risk is an uncertain situation in a project so that it can lead to consequences that can hinder the achievement of the main project objectives. Risks to the project need to be identified and analyzed in order for the project to run well. The Hidayatul Qur'an Lissa'adah Islamic Boarding School construction project is a self-managed construction project that experienced delays in its implementation time based on the results of observations and preliminary interviews with the development committee. With risk management aims to identify and reduce the risks that occur in the implementation of the Hidayatul Qur'an Lissa'adah Islamic Boarding School construction project so that the project can be completed immediately. Project delays cannot be separated from the existence of several risks that cannot be avoided, but can be minimized by risk management. In this study, identification with the Cochran q-test was carried out on the risks to determine the risks that greatly affect delays in the project, then carried out an analysis of the risks that occurred with the saverity index and then carried out appropriate mitigation actions against these risks, so that the project could be completed immediately. Based on tests and calculations using the Cochran q-test and saverity index. The results obtained through this study are that there are 4 dominant risks in the medium and high categories, namely the risk of incorrect or incomplete design (11.39%), the risk of cash flow congestion (11.39%), the risk of problematic service providers (20.25 %) and the risk of the covid pandemic outbreak (31.64%).

Abstract

Concrete is the main component of construction materials in Indonesia. Concrete composition materials consist of cement, sand, gravel, and water. Cement production in Indonesia in fact often causes polemic in the community. The community often complains of environmental pollution resulting in the cement production process. Shellfish from various mollusks like that are available abundantly along the coastal areas in Indonesia. Blood clam (Anadara granosa) is one of the many shells found in Indonesian waters and is consumed by many people because of its high protein content. Shells are part of the clam that cannot be consumed so they only accumulate into household waste. Seashell waste can be an environmental problem if not handled properly. The conch shell contains lime, silicate and alumina. The aim of this study was to determine the effect of the Anadara granosa shell as a substitute for a portion of cement in the manufacture of normal concrete. Stages of research conducted in the form of making normal concrete without any added material, making concrete with Anadara granosa shell as a partial replacement for cement, and testing the compressive strength of normal concrete samples. The optimum level of Anadara granosa shell waste as a substitute material for a portion of normal mixed concrete cement is 3% of the weight of cement used. The optimum compressive strength of concrete with Blood Shells waste as a substitute for some cement is at 30.62 MPa. The effect of Anadara granosa shell as a partial cement substitute in making normal concrete can reduce the compressive strength along with the addition of Anadara granosa shell as a partial cement substitute. Keywords: blood shells, cement, compressive strength, concrete
