Abstract

Every construction project carries inherent risks that can lead to accidents, which may range from minor injuries to deadly incidents and even fatalities. To diminish the chances of work-related accidents at the project site, it is crucial to adhere to regulations pertaining to occupational health and safety (K3). This study seeks to identify potential hazards and evaluate risk factors associated with all activities in the Bandar Lampung Library Building Construction project, as well as to analyze risk control employing the HIRARC method (Hazard Identification, Risk Assessment and Risk Control). The findings from the risk matrix assessment prior to implementing risk control indicated 75 potential risk hazards, which included: 14 activities identified as extreme risk, 47 activities in the high risk category, 12 activities classified as moderate risk, and 2 activities deemed low risk. The activities with the most significant potential hazards include: roof installation and keet directors, casting work, iron installation work, and formwork work. Following the risk control process, modifications were made in the risk level for each type of work. There were 9 potential hazards classified as high risk, 11 potential hazards categorized as moderate risk, and 55 potential hazards grouped in the low risk category. This illustrates the significance of implementing risk control measures to ensure all potential hazards can be managed and reduced.

Abstract

ITK II is an integrated laboratory building construction project currently does not involve identifying hazards, risk assessment, determining risk levels, or comprehensive risk control. The results of observations and interviews by the author show that dangers can arise due to workers' implementation, actions, and unsafe conditions. Based on these conditions, it is necessary to carry out a risk analysis with the aim of knowing what risks may occur, knowing the dominant risk level, and knowing the dominant risk response, as well as providing recommendations for effective risk control on the ITK II Integrated Laboratory Building Construction Project. The approach applied in this research includes a qualitative approach, namely at the survey, observation, interview, and distribution of questionnaire stages, and a quantitative approach is used to assess the probability and impact of risks, sort risks from highest to lowest, categorize risks, and design mitigation. risk.  The severity index method is used to calculate the probability and impact of an event. The calculation is carried out based on responses from respondents using a Likert scale and validated by experts. Then, an analysis of the risk response to the dominant risks is carried out. In the relevance test, the results obtained were 22 relevant variables and 3 irrelevant variables. Furthermore, during the validity test and reliability test, the results of the two tests obtained for each variable were valid and reliable. After that, the risk level was calculated, and 15 dominant sub-risks were obtained with a probability and impact matrix value of 9 in the "high" risk category. Risk responses that can be given are: placing safety signs in the work area, using PPE, increasing signs in each corner of the project, holding short meetings to discuss worker safety aspects regularly before starting work, wearing anti-slip shoes when working in a work environment where there is a risk of slipping, and carrying out regular field supervision.

Abstract

Roads are the primary infrastructure for land transportation, facilitating traffic from one place to another. The road from Desa Simpang/Berbak to Simpang Ma. Sabak in Muara Sabak Timur District, Tanjung Jabung Timur Regency, faces a significant issue with low California Bearing Ratio (CBR) values of the subgrade soil. These low CBR values can lead to instability and deformation of the subgrade, ultimately damaging the rigid pavement built upon it. This study aims to evaluate the influence of subgrade CBR values and concrete quality on the thickness of rigid pavement for the road from Desa Simpang/Berbak to Simpang Ma. Sabak. The research employs a quantitative approach using the AASHTO 1993 method. The results indicate that subgrade CBR values and concrete quality significantly affect the thickness of rigid pavement. Higher CBR values allow for a reduction in concrete slab thickness, while higher concrete quality increases the modulus of elasticity and flexural strength of the concrete, enabling a reduction in slab thickness. However, the influence of CBR values is more significant than that of concrete quality, particularly at higher concrete grades.In conclusion, improving subgrade CBR values is more effective in reducing rigid pavement thickness than solely enhancing concrete quality. Further economic analysis is recommended to evaluate the most cost-effective combination of concrete quality and subgrade CBR values, considering both construction and long-term maintenance costs.

Abstract

In the construction, it must be able to be used according to its function so that it can be used for a long time. The concept of construction that has sufficient strength and allows for large spaces without affecting aesthetics has emerged in recent decades. A flat slab is one of the advances in the construction system of a two-way concrete plate that distributes the working load directly to the column element without using a beam. The use of drop panels can increase the strength of the plate by resisting the sliding style of the pons and reducing the negative moment reaction that occurs on the plate and column. In the analysis, the results used a flat slab with a thickness of 200 mm, with bones in the x and y directions at the focus of As D16-100 mm and As’ D16-200 mm, whereas in the columns of column directions x and y, the field part is mounted with As D13-100 mm and As‘ D13-200 mm. In the middle column of directions X and Y, use the bones of As D13-100 mm and As‘ D13200 mm. Used a drop panel of 300 mm. For the lift area, an L type column with dimensions of 450 mm x 450 mm is used. The bars used are TB1, TB2, B1, and RB, and the columns used are 500 mm x 500 mm and 400 mm x 400 mm. The planned foundation uses a cylinder-shaped pillar with a depth of up to 8 meters.

Abstract

This study examines the planning of high-rise building structures in Indonesia, focusing on the application of Special Moment Resisting Frame (SMRF) systems under seismic conditions. Situated within the Pacific Ring of Fire, Indonesia frequently experiences significant earthquakes due to the convergence of three continental plates. Previous research indicates that the design of high-rise buildings necessitates careful attention to dimensions and reinforcement to ensure structural strength and stability. The SMRF planning method, which applies the principle of strong column weak beam, has been analyzed across various case studies, including designs for office buildings, hotels, laboratories, and educational facilities.Furthermore, this study compares the structural performance using different concrete strengths, specifically 41.5 Mpa and 24.9 Mpa, in the construction of prison walling at the Kejati Detention Center. Through quantitative analysis and structural modeling using ETABS V.20 software, this research identifies differences in base shear and inter-story drift between the two concrete strengths. The findings provide insights into the effectiveness of higher-grade concrete usage and its potential impacts on the strength and structural quality of buildings. The implications of this research can guide practitioners in selecting the appropriate construction materials to enhance performance and cost-efficiency in high-rise building projects in Indonesia.

Abstract

This research aims to determine the costs required to build a guard post building in the border area of Papua, Indonesia and Papua New Guinea. It is hoped that this research will contribute to improving the national defense, especially regarding the construction of guard posts in national border areas. This research discusses the construction of the guard post by describing the volume of work and the planned cost budget, and the data collection methods used are primary and secondary data. In this research, guard post drawings were planned according to the standards of the Indonesian Army and supporting data in the form of Unit Prices for Goods and Services (SHBJ) in the Papua region, as well as the Ministry of PUPR's Unit Price Analysis Guidelines. Apart from that, the type of work along with the volume of work is arranged followed by an analysis of the unit price of each job. Then the Cost Budget Plan (RAB) is calculated to get the total price for each job. Thus, the total cost required to build a guard post building on the Papua border is IDR 119,441,000.00. In the future, it is hoped that this research can become a reference for building guard posts around the Papua border area.

Abstract

Customer satisfaction is a feeling of pleasure or disappointment of a customer that comes from a comparison between his impression of the performance or results of a product and his expectations. Performance measurement is a method used to provide an assessment of how much the level of work performance or achievement of predetermined goals and objectives. Buy The Service (BTS) is a service purchase subsidy scheme by the government to the operator (private) in terms providing public transportation services with minimum service standards that must be implemented. Transpakuan has been officially operated since November 2, 2021, serving 4 corridors with a total of 49 fleets. One of them is corridor 1 (Terminal Laladon - Cidangiang). A satisfaction assessment is needed to see whether Biskita Transpakuan Bogor customers are satisfied with the service. The indicators used in the evaluation refer to the Regulation of the Minister of Transportation of the Republic of Indonesia Number 27 of 2015 concerning Amendments to the Regulation of the Minister of Transportation Number 10 of 2012 concerning Minimum Service Standards for Road-Based Mass Transportation. This study aims to determine public satisfaction and the level of performance of Buy The Service (BTS) Biskita Transpakuan Corridor 1 services using the Importance Performance Analysis method & the Customer Satisfaction Index method. The results showed that there are 4 (four) attributes that show consumers are satisfied and must be maintained. There are 6 rated ordinary and 7 (seven) attributes rated excessive. The CSI results show a value of 72.79% in the interval 0.51-0.65, meaning that in general Trans Pakuan bus consumers are in the satisfied category, so that Trans Pakuan's overall performance is considered good. Based on the Importance Satisfaction Analysis method, it shows that the aspects that need to be prioritized are the convenience of cleaning facilities at bus stops, waiting time, information on the arrival time of bus cars and information on disturbances.
