Abstract

One of the strategic issues facing the City of Sungai Penuh is flooding, as indicated by the Detailed Spatial Planning (Rencana Detail Tata Ruang or RDTR) for the years 2021–2024. Despite efforts to manage the drainage, there is currently no digital-based drainage asset database in the City of Sungai Penuh. The aim of this study is to optimize the asset database used by the Geographic Information System (GIS) at the Public Works and Housing Agency (Dinas PUPR) of Sungai Penuh. The objective is to enhance the efficiency of asset management owned by the Dinas PUPR of Sungai Penuh in terms of utilization, management, and maintenance. This research employs the waterfall method for system design and part analysis to evaluate the condition of the asset database. According to this study, the drainage infrastructure asset database system still does not meet user needs from various perspectives. Several aspects require improvement. The development of a drainage infrastructure asset database through the implementation of a Geographic Information System (GIS), aligned with findings from questionnaires and analysis using the PIECES framework, has proven to meet user expectations. This is particularly evident in the aspects of delivering relevant information, data security, and the availability of adequate services. This evaluation can be substantiated through the average Satisfaction Response (RK) score, which indicates user satisfaction levels ranging from satisfied to very satisfied.

Abstract

Kota Depok, located in the western part of West Java Province, has experienced rapid growth over the past few decades. This growth occurred alongside intense urbanization, industrial development, and population increase. Apart from the positive impact of economic growth and infrastructure development, this rapid development causes environmental damage and loss of green open land. This can impact air, water, and soil quality and threaten environmental sustainability. This paper systematically tries to inventory the factors involved in urban green spaces' sustainability with a structural approach using Cross-Impact Matric Multiplication Applied to Classification (MICMAC) software. Of the 12 factors analyzed, five have a strong level of influence and low dependence, and 3 have a strong influence but have high reliance. These factors are 1) LU policy, 2) law enforcement, 3) environmental education, 4) stakeholder integrity, and 5) community involvement and participation, while 1) biodiversity conservation, 2) land value, and 3 ) environmental maintenance and protection is a factor that has a strong influence but is also highly dependent. Stakeholders can use the results of identifying these key factors as considerations for making decisions.

Abstract

Tanjung Setia Beach is located in the West Coast area of Lampung Province. This location is very vulnerable of disaster such as tsunami, because it is on the edge of a geologically active continent with a coastline facing the Indian Ocean and distinguished by the confluence of tectonic plates. With such conditions at any time a tsunami disaster can occur and cause damage to the area. One of the weaknesses in the Tanjung Setia coastal tourist area on, West Coast of Lampung Province, is non exist of hazard maps or KRB (Disaster Prone Vulnerability) maps made by the National Center for Volcanology and Disaster Mitigation. Modeling the propagation of tsunami waves by determining the distribution pattern of tsunami waves and implementing several planned wave height values and historical wave height is a basic step of disaster mitigation in the area. Using Delft3D 4.04.01 software based on data and scenario analysis can produce wave propagation in the area. The height and wave period of the plan are calculated using the hindcasting method and are based on the SPM 1984 standard and then used as input in Delft3D modeling software. From the calculation results, the height and wave period of the maximum plan for the 15 year is 3.01 m with a period of 8.21 s, the 25 year is 3.16 m with a period of 8.49 s and the 50 year is 3.37 m with a period of 8.87 s. In addition, historical tsunami wave heights of 3.6 m, 8 m and 15 m are also used as inputs in the Delft3D model. The results of propagation planned wave does not cause a significant tsunami disaster. As a result of wave propagation based on the historical height of tsunamis used, 3.6 m wave does not cause tsunami disasters in the area and take 35 minutes to reach coastal areas, while waves of 8 and 15 meters are able to cause tsunami disasters on land, which takes 27-34 minutes to reach the coast. All three scenarios qualify for model accuracy in shallow seas. From the results of mapping using GIS software, the maximum propagation of the scenario of high waves of 8 meters on land as far as 803 meters and waves of 15 meters as far as 872 m from the coastline.

Abstract

PT X, a company operating in the Fast Moving Consumer Goods (FMCG) sector located in East Jakarta, is expanding its Distribution Center (DC) to help increase distribution rates. Selecting the right contractor can help expedite the supply chain and shape the company's strategy. PT X faces several issues related to contractor selection with various criteria in the DC construction process. To address these issues, careful contractor selection is necessary. Multi-Criteria Analysis (MCA) methods such as Simple Additive Weighting (SAW), Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS), and Multi-Attribute Utility Theory (MAUT) are used in the contractor selection system. The SAW and MAUT methods have advantages in simple and easy calculations, while TOPSIS excels in detailed data processing. This study aims to compare these three methods in contractor selection for the DC construction tender. The research data were obtained through questionnaires and interviews with stakeholders and PT X management. The analysis results show that, based on Euclidean Distance (ED) and Average Error Rate (AER), the MAUT method is considered more suitable for application at PT X, with an ED value of 0.4012 and an AER of 0%.

Abstract

One of the estuaries in Bengkulu Province, the Air Hitam River Estuary, has gradation and estuary drift problems based on Google Earth satellite observations annually. The cause is the occurrence of high sediment material and the phenomenon of longshore currents. The structural solution is the design of a jetty structure with a long type because the estuarine condition causes the need to remain open. This coastal protection aims to maintain estuary stability and regulate the stream flow. The methods used in the research methods are the Admiralty method in the processing of tidal data and the Hindcasting method from CERC in the processing of wind data. The results of the analysis provide a jetty length of 270 m with a width of 200 m between jetties. The left and right jetties have a peak width of 3 m and the highest building is 4 m from sea level with high tidal parameters of HHWL, MSL, and LLWL conditions are 78.21 m, 0.04 m, and -78.36 m, respectively. The breaking wave analysis derived a height of 2.50 m at a depth of -3.22 m which is utilized for infrastrcture dimension analysis. The coastal protection materials used with a 1:2 building slope on both jetties are tetrapods for the first and second layers, and boulders for the core layer. Used 0.5-2 tons weight of tetrapods for both sides of the jetty, 0.44-16.71 kg and 0.18-16.71 kg weight of boulder stones for both sides of the jetty, and toe protection used boulder stones weighing 43.69-157.28 kg and 18.39-157.28 kg for both sides of the jetty. Based on the literature study and estuary conditions, this design is capable of maintaining estuary stability and control river flow effectively.

Abstract

Ponds are key structures in flood control strategies, especially in industrial areas which have a high vulnerability to excess air runoff. The main risk faced is the potential for air overflow from the pond, which could cause serious damage downstream, including the risk of embankment failure and damage to the spillway. Therefore, controlling the water level in the pond is very important, especially in dealing with high-intensity flooding events. When the water level reaches the specified threshold, the water in the pool must flow in a controlled to the drainage channel through the spillway. This research uses the HSS Nakayasu method to estimate flood discharge entering the pond. At the same time, the calculation of the spillway is carried out based on the reservoir capacity of the pond and the planned spillway design. The research results show that the flood discharge entering the pond at various return periods, namely 5, 10, 20, 25, 50, and 100 years, ranges from 19.53 m³/s to 33.78 m³/s. The discharge from the spillway varies from 5,03 m³/s to 8,68 m³/s at the same return period. The maximum flood water level above the spillway varies from 0,90 m to 1.30 m, with the increase in water level from the bottom of the pond (elevation +20.00 m) reaching +24.90 m to +25.30 m. Further calculation results show that at a return period of 100 years, the pond is able to reduce flood discharge by up to 74%, with 26% of the flood discharge being channeled gradually through spillways and drainage channels to the river. The effectiveness of the spillway in reducing the risk of runoff confirms that this pond functions as a reliable flood mitigation solution for the shoe factory industrial area in Pekalongan Regency, Central Java Province.

Abstract

Walking is the simplest form of transportation and can be used by everyone. The decline in the desire to walk is associated with the reduced service functionality of sidewalk infrastructure. This study examines pedestrian perceptions regarding the service functionality of sidewalks on DR. Ratulangi, AP. Pettarani, and Gatot Subroto streets in Banggae Subdistrict, Majene Regency. The perception assessment study uses a qualitative and quantitative descriptive statistical approach, referring to the Ministry of Public Works and Housing Regulation No. 03-2014, which provides guidelines for planning, providing, and utilizing infrastructure and pedestrian network facilities in urban areas. The analysis results indicate that the use of sidewalks is mainly driven by considerations of time and safety while walking. Respondent perceptions show that the aspects of comfort, safety, and connectivity on the streets studied fall under the "fairly good" criteria. Based on the existing perceptions, respondents expressed a desire for improvements and enhancements in these variables, which are expected to increase both interest and the need for walking using sidewalk facilities.

Abstract

Change Orders (CO) represent a significant challenge in the construction industry, often leading to substantial adjustments in project budgets. COs, encompassing both scope additions and reductions, can result in discrepancies between initial budgets and final project costs, thus affecting project profitability and sustainability. To measure the impact of CO on budgets, this study employs the Change Order Ratio (COR) and its components: CORA (Change Order Ratio in Addition) for budget increases and CORS (Change Order Ratio in Subtraction) for budget reductions. This research analyzes data from 36 construction projects managed by PT XYZ in Indonesia from 2020 to 2024, with aims to (1) identify patterns in budget changes, (2) assess the statistical significance of CORA and CORS on COR, and (3) recommend contingency budgeting strategies. Findings reveal that both CORA and CORS have a significant impact on COR, with average values of 13.32% for CORA and 9.30% for CORS. Based on these findings, a contingency budget of 10-15% of the initial contract value is recommended. This study underscores the importance of effective CO management, particularly in anticipating scope additions, to maintain budget stability and enhance the accuracy of financial planning in construction projects.

Abstract

The use of large volumes of concrete often results in damage such as honeycombs and cracks, which can threaten the strength and durability of the structure. One method of repairing such damage is through demolition. However, demolishing concrete structures due to defects can be costly. Technology advancements have led to the development of repair methods that do not require dismantling the structure. This can be done with Root Cause Analysis (RCA) to identify the factors causing the damage, as well as Forensic Assessment using Ultrasonic Pulse Velocity (UPV) and Ultrasonic Pulse Echo (UPE) to assess the condition of the concrete. The analysis showed that there were several main factors that caused the damage, including the use of inappropriate vibrators and a lack of worker skills. This research demonstrates that not all damage requires total demolition; there are various repair methods that can extend the lifespan of the structure without incurring high costs. This research provides a step for construction management in aligning repair strategies to improve the durability and safety of concrete structures in power plants.
