Abstract

Tectonic earthquakes are a type of earthquake that can cause significant damage compared to other earthquakes. These tectonic earthquakes often occur in Indonesia, considering that geographically Indonesia is located between active earth plates. So that in earthquake-prone areas it is necessary to plan earthquake-resistant building structures, this is done so that if an earthquake occurs the building does not suffer significant damage. The dynamic response spectrum analysis method produces the base shear and displacement of the structure. The response spectrum is a spectral plot presented as a plot or graph between periods of oscillation of a T-structure, as a function of the maximum response to a certain attenuation rate and seismic load. This study aims to determine a structural response with 3D modeling on a hospital structure in the city of Solo. The study was conducted to determine the effect of the earthquake on the performance of the structure which was analyzed with reference to the regulations of SNI 03-1726-2012 and SNI 03-1726-2019. The modeled building consists of floor slabs, beams and columns, each of which is structurally load refers to the regulations of SNI 1726-2012 and SNI 03-1726-2019 as a comparison which one is more effective. The results obtained from the use of SNI 03-1726-2012 on building structures have better safety performance when compared to analysis with SNI 03-1726-2019.

Abstract

The blacksmith business in Segaran Village, Delanggu Subdistrict, Klaten Regency is one of the SMEs with high economic potential but lacks in the implementation of occupational health and safety (OHS) standards. This condition leads to high risks of workplace accidents such as burns, sharp tool injuries, and exposure to fumes and extreme heat. This community service activity aimed to enhance the awareness and capacity of SME actors in applying OHS principles through socialization and direct assistance. The methods included observation, interviews, education, PPE usage simulations, and behavior change monitoring. The results indicated an increase in OHS awareness and practices, including the use of personal protective equipment and better workspace organization. The assistance encouraged the creation of a safer and more sustainable work culture. This activity had a positive impact on the productivity and safety of blacksmith SME workers.

Abstract

Earthquake-resistant structures are vital to achieving sustainable buildings as they minimize damage during seismic events and allow for easier repairs. In contrast, non-engineered buildings (NEBs) often suffer severe damage, contributing to waste that burdens the environment. Many residential buildings in Indonesia fall into this NEB category, so evaluating the extent of damage during earthquakes is essential. This study analyzed the seismic response of NEB using Incremental Dynamic Analysis (IDA). The dynamic pushover curves derived from the IDA were further examined to identify the damage limit states pertinent to NEB, considering the randomness of the ground motions. The proposed damage limit states, categorized into various levels (DS1-DS4) and their corresponding uncertainties due to random ground motions, highlight the vulnerability of NEBs to seismic events. The high probability of damage to NEBs makes stakeholders aware of the need to take measures to improve the resilience and, ultimately, the sustainability of residential buildings.

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

Abstract

The growth of the number of motorized vehicles in Indonesia every year always increases. The consequence of the growth in the number of motorized vehicles is the increasing production of motorized vehicle tires which results in the accumulation of used tire waste. One of the innovations to reduce the waste of used tire rubber is to use it in asphalt mixtures. The study was conducted to determine the change in the index of retained strength in the Asphalt Concrete – Wearing Coarse (AC-WC), is the top layer of pavement which functions as the wear layer,  mixture with the addition of waste rubber from used tires (crumb rubber) meeting the Bina Marga Specifications. The results showed that the addition of waste rubber tires affected the marshall characteristics, namely, the highest specific gravity, density, Voids Filled With Asphalt (VFA), and stability values were at a level of 1%, while the highest values of Voids in Mix (VIM), Void in Mineral Agregate (VMA), and flow were at a level of 9%. From the index of retained strength test, it shows that water affects the durability of the AC-WC mixture, as evidenced by the highest value at the duration of immersion for 24 hours with a concentration of 1%, which de-creases with increasing duration of immersion. The addition of used tire rubber waste (crumb rubber) to the AC-WC mixture has met the Bina Marga Specifications on the Marshall characteristics test, but the change in the index of retained strength was only for a 24-hour immersion duration, while for other durations were not according the Bina Marga Specifications.

Abstract

The background of this research is that plastic waste is abundantly available around us and has not been optimally utilized. Pedestrian which is also the right of pedestrians with disabilities has not been well organized in Indonesia. The use of plastic waste materials is an alternative to solving environmental problems. The utilization of plastic as a substitute for cement will also reduce the carbon effect of cement as a building material. With its light weight when compared to disabled terrazzo tiles on the market, it is hoped that it can facilitate the application of smart pedestrian blocks as pedestrian paths and disabilities. The purpose of this research is the utilization of plastic waste as used as composite thermoplastic waste brick as well as an alternative eco friendly material. The experimental method used normal paving, 45% plastic waste, 55% plastic waste, and 65% plastic waste. The test results show that the average compressive strength for paving with 45% plastic waste has a compressive strength of 9.16 MPa higher than normal paving which is only 8.56 MPa. This shows that the use of 45% plastic waste as an effective substitute for cement in paving is also an environmentally friendly solution. In addition to reducing plastic waste, it also reduces the need for cement.
