Abstract

The implementation of construction projects in the Regional Government of West Pasaman Regency almost every year there is always a termination of the contract which results in not achieving the government's goal of increasing the standard of living of the community because the targets set by the Government are delayed and hampered. This research was carried out which aims to identify the causes of contract termination in the implementation of construction service procurement in West Pasaman Regency, analyze and evaluate the causes of contract termination in construction implementation, and determine recommendations for improvement to prevent contract termination in the implementation of construction service procurement in Pasaman Regency West. This study uses descriptive qualitative analysis based on the results of interviews with CMO and TIO for work that has terminated its contract and analyzes administrative data on termination of contracts for construction work which has experienced termination of contract. The methods used in the discussion to find out the factors that cause construction contract termination are the Fault Tree Analysis (FTA) Method and the Obtain Cut Set (MOCUS) Method. From this study it can be concluded that the main factor causing the breakup of construction contracts is the owner's firmness with the performance of the provider, the provider being evaluated is unable to carry out the work, the contract termination should be carried out earlier, not waiting for the end of the year and not providing an extension of the implementation period past the fiscal year and the owner is negligent. in controlling the contract. While the supporting factors that cause the termination of the contract are the provider's fault, namely poor project management, the practice of borrowing company flags, not having capital, not heeding the instructions of the owner and field supervisor as well as other factors, namely disturbance factors from the community around the work location, weather, selection of providers and material supply. For recommendations for future improvements, it is recommended that the owner carry out control of the construction contract more optimally and the provider is more professional at work. This study analyzes the factors that cause construction contract terminations only from the owner's point of view, therefore further research is still needed from the point of view of job providers and supervisors to see the characteristics and possibilities of other different factors.

Abstract

Padang Eye Center is one of the hospitals under construction on Jalan Khatib Sulaiman, Lolong Belanti, North Padang District, Padang City, West Sumatra. The construction of the hospital will certainly have an impact on traffic on Jalan Khatib Sulaiman. The purpose of conducting andalalin is to analyze the amount of travel demand that occurs at the Padang Eye Center Hospital in pre-construction, construction period, operational period, and post 5 years of construction, as well as seeing the impacts that occur and how alternative solutions are carried out. The parameters used are based on the Regulation of the Minister of Transportation of the Republic of Indonesia Number 17 of 2021 concerning the implementation of andalalin, the Indonesian Road Capacity Guidelines (PKJI) of 2023 concerning the performance of road sections and the Directorate General of Land Transportation of 1996 concerning parking. The results of the analysis, namely the existing conditions obtained a V / C ratio of 0.43 level B, the construction period obtained a V / C ratio of 0.45 level C, the operational period with a V / C ratio of 0.45 level C, and after 5 years of operation the V / C ratio is 0.58 level C which means that the flow is stable, but the operating speed begins to be limited based on the level of service (LOS) table. Parking needs based on the building area of 2832 m2 were obtained as many as 113 srp, while based on the available parking area it can accommodate as many as 121 srp, so the parking space requirements of the Padang Eye Center Special Eye Hospital have been met. The alternative solution to this analysis is the placement of regulatory officers in front of the entrance and exit of the Khatib Sulaiman Road intersection during the construction period, regulating parking circulation within the hospital area, and making barrier gates to regulate vehicle traffic flow.

Abstract

Lateral spreading, a complex phenomenon resulting from liquefaction, manifests when saturated, cohesionless soils lose their strength during seismic events, causing them to deform and flow horizontally. This process poses a substantial risk to buildings and infrastructure, often resulting in extensive damage, significant financial burdens, and, tragically, loss of life. In Indonesian, liquefaction is recognized for its ability to transform solid ground into a fluid-like state, amplifying its danger in regions prone to earthquakes. This study aims to analyze lateral spreading through empirical methods, specifically employing the Bartlett & Youd Method (2002) and the Byrne Method (1990). The analysis focuses on sites previously affected by lateral spreading, notably those impacted by the 22 February 2011 Christchurch earthquake, which registered a magnitude of 6.2 and a peak ground acceleration of 0.52. The selected locations include the South Brighton Bridge, Anzac Bridge, and Fitzgerald Bridge in Christchurch, New Zealand. The findings demonstrate that both the Bartlett & Youd Method (2002) and the Byrne Method (1990) yield results that closely approximate the actual conditions at site.

Abstract

Indonesia is an area that is prone to hydro-meteorological natural disasters such as floods, landslidesand so on. In Indonesia, especially West Sumatra, the cause of flooding is dominated by high rainfall, as is the case in the Gasan Gadang watershed. In an effort to overcome problems resultingfromflooding, there are several ways, one of which is knowing the causes of flooding and the target areafor flooding, which depends on the characteristics, hydrology and physical conditions of the area. Themain objective of this study is to determine the level of vulnerability to flood disasters and tomapflood-prone areas in the Batang Gasan watershed area to obtain the level of vulnerability andverifyflood-prone areas with measurement results. This research uses several stages of analysis, namelyweighted product (WP) analysis and dynamic analysis. The research results show that areas that havea high level of flood vulnerability are IV Koto Aur Malintang sub-district and Batang Gasansub- district. The area that is vulnerable to moderate-scale flooding is Tanjung Mutiara District. Andthearea that has a low scale flood vulnerability is Sei Geringging District. For areas that are pronetohigh-scale flooding, using the Dynamic Analysis method, the area area can be reduced over the next two year period. And in the 10th (tenth) year the flood area can be reduced by 85.88%. Efforts madeto reduce the area of the flood area are by installing check dams and dredging sediment along the river for District IV Koto Aur Malintang and Batang Gasan District.

Abstract

In conducting logistical activities of disaster relief in natural disaster management. it is often not possible to implement as it should. and there are always potential risks that arise. One of the problems faced is the delayed distribution of post-disaster logistics. Therefore. risk management is necessary so that disaster relief logistics activities can run well. In addition. there is a need for a risk mitigation strategy to mitigate potential risks in the post-disaster logistics distribution process. The study aims to identify potential risks to post-disaster logistics distribution activities and find out which risk management strategies are a priority to address immediately. Failure Mode and Effect Analysis (FMEA) is a systematic approach to identifying failures and giving a value or score to each risk. From the results of the study. 32 potential risks occurred. As a result. 13 risks were identified with RPN values above critical point values. Thus. 13 were obtained as priority management risks. where the risks with the top 3 RNA values are Disruption of the post-earthquake telephone network Difficulty coordination of the logistics team with a rating of 25.98. Long logistic delivery travel time with a value of 21.86. and Condition of the vehicle used is not good with a score of 21.66. Thus. for 13 of these risks. mitigation is carried out for treatment priorities. Risk management strategies are applied to risks that have RPN values above critical values to minimize the impact.

Abstract

Gresik Regency is a coastal area with a significant mangrove population, notably in the Ujungpangkah region. The Ujungpangkah mangrove forest is a designated ecotourism and conservation area. However, due to management and utilization practices by the local community, the mangrove ecosystem in Banyuurip Village, Ujungpangkah District, has experienced a decline. This study aims to determine the mangrove density in Banyuurip Village using vegetation index transformation methods (NDVI and DVI). Assessing the density of mangrove vegetation is crucial for the effective management of mangrove forests to ensure they fulfill their ecological functions. The research employs a quantitative method, utilizing Landsat 8 imagery data to measure mangrove density using the NDVI and DVI methods. The study results indicate that the NDVI canopy density classification is 86.67%, divided into three classes: dense (569.700 ha or 95.32%), medium (29.910 ha or 4.50%), and sparse (1.080 ha or 0.18%). Meanwhile, the FCD classification results are 73.33%, also divided into three classes: dense (583.740 ha or 97.67%), medium (13.410 ha or 2.24%), and sparse (0.540 ha or 0.09%). The NDVI method proved to be the most accurate for classifying canopy density based on the accuracy test data

Abstract

In the building establishment process, the geotechnical characteristics of soil have a significant impact on the structural performance of buildings. Therefore, soil mapping becomes a critical step in understanding the properties of soil that can affect foundation and structural stability. The mapping method used is open polygon mapping, which allows flexibility in determining land boundaries. Measurements were taken at three survey points: roadside, middle of the field, and edge of the field. The mapping results reveal variations in soil characteristics that need to be considered in development planning to ensure solid and stable building foundations. The implementation of Geographic Information Systems (GIS) in this process facilitates deeper data analysis and better visualization of field conditions. The mapping results show significant variations in ground elevation at each survey point, emphasizing the importance of understanding the area's topography. Additionally, area measurements were conducted using open polygon data, providing fundamental information for area development planning. Contour maps generated through Surfer software provide clear visualization of ground elevations at each survey point, enhancing understanding of the area's topography. This research contributes significantly to understanding soil characteristics and topography in the rear area of Mojoroto. It is expected to serve as a guide for area development planning, ensuring the stability and safety of future building structures. Thus, soil mapping is a critical step in ensuring the safety and sustainability of future buildings and contributes to sustainable area development planning.

Abstract

Land mapping is an important research activity to determine the location of points on the earth's surface, describing the physical condition of parts of the surface that resemble the actual condition. The objective of this process is to gain a comprehensive understanding of the land to be built and used through land area measurements, topographic maps, and land volume analysis at various altitudes. In this mapping, the open polygon method is used for calculations which are conventional methods using data point values as data centers to represent the area of influence. During this mapping, there are three main points used with the open polygon method. A total of 26 ground contours were recorded, and 4 road contours recorded. During the mapping process, corrections are required on the open polygon calculations to ensure the accuracy of the results. This correction involves adjusting the data to take into account field variability and inaccuracies of measuring instruments, so that the resulting data can be reliable for further analysis and correct decision-making. The land that has been painted can be used for various fields such as construction, and mining. Land mapping allows partial surface physical state imaging, classification of land, and can be used to plan, build, and maintain infrastructure such as highways and bridges. The result of this practice obtained data of the maximum height of 90,0945 masl and minimum 88,76 masl with the average ground height 90,05059 masl, while the average highway height is at 88,86175 masl.
