ANIK RATNANINGSIH — 2024-12-30

The rapid growth of the population in an area requires an increase in housing. This is a challenge for sustainable
housing construction. One of the responsibilities necessary is the risk management of work accidents in
construction. This study aims to determine the identification, assessment, and mitigation actions for the risk of
work accidents in housing construction. The data collection process was carried out by distributing
questionnaires to housing project workers in Paser Regency, East Kalimantan. Identification of work accident
risk is carried out using the HIRA (Hazard Identification and Risk Assessment) method. Assessment of each
work accident risk using the ERM (Enterprise Risk Management) Interface method. Mitigation actions on
dominant risks are carried out in coordination with the project HSE. The identification results using the HIRA
method show that there are 17 risk factors for work accidents. Assessment of each risk using the ERM Interface
method resulted in 7 risk factors with low category, eight risk factors with medium category, and two high
category risk factors. Some mitigation actions from coordination with HSE on dominant risk factors include
installing warning signs in all project areas, conducting routine safety patrols, installing work area safety
barriers, and workers using body harnesses/safety belts.

One of the natural disasters that always occurs in Indonesia is floods. Floods are caused by unchanging
natural factors, such as geography, topography and river flow. Flood disasters are also included in hydrometeorological disasters. According to the Indonesian Disaster Information Data (DIBI), the National
Disaster Management Agency (BNPB) from 2005 to 2015, more than 78% (11,648) of hydrometeorological
disasters occurred, and 22% (3,810) of geological disasters occurred. According to the findings of the BNPB
study, flooding resulted in quite large losses, namely that there were more than 170 million Indonesian people who were threatened by flooding, and the value of their exposed assets was more than IDR 750 trillion. The results of this review became parameters for researchers to conduct pre-disaster mitigation research in the form of providing posters containing disaster mitigation material to communities in areas prone to flood disasters. The choice of poster media was because the information conveyed was easier to reach and understand by the public. In this study, researchers used a measurement tool in the form of a questionnaire which was distributed to 96 respondents so that initial understanding could be identified through the Pretest and improvements after being given poster media through the Posttest. The results of the data analysis showed that the knowledge value of the people who were respondents in this study was considered better and the Wilcoxon test showed that the results were <0.05, indicating that poster media was effective as a medium for supporting disaster preparedness in Jember Regency.

I Wayan Wiguna Putra — 2024-12-30

The Pidada area is an area of North Denpasar District with a high population density. During the rainy season, this residential area experiences flooding and it recurs every year. One of the areas where flooding often occurs is in the Pidada road area, which is thought to be due to the drainage system's performance not being optimal. This possibility is caused by reduced drainage capacity during the rainy season, increased water discharge, and sedimentation. Based on field observations, it was also found that the increasing conversion of agricultural land into residential areas without consistent addition or improvement of drainage infrastructure resulted in disruption of the drainage system in the Pidada settlement. From the calculations described in CHAPTER IV, several alternative combinations of heavy equipment requirements for drainage work projects in the Pidada road area are drawn as follows: From the results of calculating the productivity of the Komatsu PC 78 Mini Excavator, PC 75 Excavator and Hino 130 HD Dump truck, it was found that the heavy equipment productivity figures were: Komatsu PC 78 Mini Excavator = 41.4 m3/hour, Excavator PC 75 = 24.1 m3/hour, Dump Truck Hino 130 HD = 4,289 m3/hour. From the results of the combination of heavy equipment obtained in alternative 1, it is more effective and efficient than alternative 2, which can be concluded as follows: Alternative 1: Total Cost for 4 Days = Rp. 54,080,000, Alternative 2: Total Cost for 6 Days = Rp. 69,120,000.

Ubud is an area with a high level of busyness and often experiences traffic jams caused by high traffic
volumes and vehicles of visitors to the Ubud Art Market that are parked on the road so that the road capacity
is reduced. The peak of parking volume that affects traffic on Ubud Highway usually occurs during peak
hours such as 13.00-15.00 noon and 17.00-19.00 at night. This study aims to determine the effect of road
parking on the level of road service Due to parking on the road body, the capacity of Ubud Highway has
decreased by 33.92% or 1265.36 smp/h and Monkey Forest road has decreased by 37.63% or 1309.35
smp/h. The width of the road is reduced due to parking and side obstacles become high and there is no
availability of off street parking for cars. The existing condition of road performance on the Ubud Highway
section due to on-street parking on weekdays (Tuesday) is obtained at the level of E service and on holidays
(Sunday) the level of service on F road is obtained with poor traffic flow characteristics, namely traffic

STUDI KELAYAKAN TEKNIS DAN BIAYA PEMBANGUNAN TEMPAT PEMBERHENTIAN BUS TRANS METRO DEWATA KORIDOR 2

I Gusti Kade Ari Pradnyana — 2024-12-30

Determining the location and number of stops has an important role in
using the BRT mode. Improper construction of bus stops will result in increased
transportation problems, because many people who should be the target users
become reluctant to use this mode because of difficulties when using existing
facilities. The main reason why passengers do not use bus stops as a place to get
on/off from public transport is that the distance they have to travel to get to the bus
stop is too far. With the increasing number of bus stops being built, it means that
the level of accessibility of bus services is increasing. However, on the other hand,
building too many bus stops can lead to greater construction and maintenance
costs. Because of the large costs required to build a bus stop, it is necessary to make
the construction of the bus stop effective. Data collection is an activity to search for
data in the field that will be used to answer research problems. In this case, the
researcher also collected secondary data, where the data was obtained from parties
who have data on the number of passengers, bus data, and bus stop location data.
Global priorities are an assessment of the final weight of decision alternatives so
that it can be concluded which bus stop is the main choice for waiting for arrivals.
Trans Metro Dewata bus corridor 2, ranked first is the Dewi Sartika bus stop with
a score of 27.6%, second place is the SMP 10 bus stop with a score of 22.9%, third
place is the Gedung Dharma Alaya stop with a score of 20.3 %, ranked fourth by
the Suli 2 bus stop with a value of 15.4%, and last ranked by the Kerta Sari bus stop
with a value of 13.8%. The technical condition of the bus stop on corridor 2 has 69
stopping points. From the survey results, it was recorded that there were only 5 bus
stop houses, 46 bus stop poles and 18 points that did not have signs. At each
stopping point, it was assessed that there was still minimal information regarding
the bus route.

Public transportation is essential for supporting daily societal activities, providing access to all
groups through a rental/payment system. Urban transportation, defined by predetermined routes and
designated stops, is particularly significant in urban areas. In Bali Province, urban transportation is
divided into two systems: Trans Sarbagita, operating on 2 corridors, and Trans Metro Dewata, with 5
corridors. Data for this study was collected through surveys and observations, focusing on passenger
boarding and alighting numbers, headway, travel time, waiting time, and operational performance. The
analysis compared these metrics against established performance standards.The headway analysis
revealed an average of 15.20 minutes, meeting the standards set by the Directorate General of Land
Transportation. However, the load factor averaged 35,07 %, with 45,55 % on weekdays and 24,6 % on
holidays, falling short of the required standards. Conversely, the travel time of 111.6 minutes and waiting
time of 11 minutes were within acceptable limits. The insufficient load factor is primarily due to inadequate
outreach and information dissemination to the public, which has limited public interest in using Trans

TINJAUAN PENERAPAN KONSEP BALOK LEMAH KOLOM KUAT PADA BANGUNAN BERSERTIFIKAT LAIK FUNGSI (SLF) (STUDI KASUS BANGUNAN KOMERSIAL DI JALAN DEWI SRI, KUTA)

I Made Utha Payusa — 2024-12-30

The Certificate of Feasibility is a crucial document for any building. With an SLF, it can be ensured that the building is fit for occupancy. One of the safety requirements for a building is the structural requirements. A building structure can be considered fit for occupancy when it meets the applicable standard regulations. One of the structural requirements for buildings implementing a special moment-resisting frame system (SMF) is the weak beam strong column concept. This concept is applied to ensure that the column strength exceeds the beam strength. To review the application of the weak beam strong column concept in buildings with a Certificate of Feasibility, an analysis of the existing structural components and earthquake[1]resistant building analysis must first be conducted to ensure compliance with the applicable standards. From the analysis conducted, several discrepancies were identified, including the area and spacing of the column stirrups, the shear strength of the beam-column joints, and the stirrup area in the beam-column joints. From the earthquake-resistant building analysis, it was found that the inter-story drift was below the allowable limit and the P-Δ effect stability coefficient was less than the permissible coefficient. In the review of the weak beam strong column concept, it was found that the nominal axial load of column K1 was 2239.14 kN, the nominal moment of the beam at the negative support area was 237.47 kN.m, and at the positive support area was 162.62 kN.m, resulting in a nominal moment of 259.26 kN.m at the lower column and 220.85 kN.m at the upper column. Using the interaction diagram by projecting the Pn and Mn values, it was determined that the intersection of Pn and Mn remained within the influence boundary of the 1.6% reinforcement area. Thus, the weak beam strong column concept was fulfilled. The reinforcement installed at the interior beam-column joint in the X direction was 5 D13-75, and in the Y direction was 3 D13-75. At the exterior joint in the X direction, the reinforcement was 4 D13-100, and in the Y direction was 4 D13-100. At the corner joint in the X direction, the reinforcement was 3 D13-100, and in the Y direction was 4 D13-100.

Cost and time are factors that influence the success and failure of a project. This is a parameter for the success of a project which can be seen from the completion time and minimum costs but with guaranteed quality in accordance with planning. In project implementation, discrepancies often occur between the planned schedule and the realization in the field. This results in delays in project completion. To overcome this problem, it is necessary to accelerate the project implementation time. In this research, work will be accelerated using a method of increasing working hours (overtime) and the number of workers. The aim of this research is to determine the comparison of time and costs between accelerating the addition of overtime hours and additional labor by calculating the comparison using Excel. The analysis results show that the initial project cost was IDR 52,463,000 with an implementation time of 32 days. If we compare project acceleration with additional working hours (overtime), we get an additional cost of IDR 69,611,000 with an implementation time that is 25 days faster, while acceleration by increasing the number of workers results in an additional cost of IDR 58.105,000 with an implementation time that is 20 days faster. For additional overtime working hours, the duration is reduced by 7 days. Meanwhile, with the addition of labor, the duration is reduced by 12 days.

ANALISIS METODE DAN BIAYA PERKUATAN BALOK KANTILEVER PADA PROYEK WONDERLAND ULUWATU

Alda Tertia Marella — 2024-12-30

A strong and durable structure is the expectation for every building. However, in the implementation of concrete manufacturing projects, there are still many issues due to the quality of concrete not meeting the plan specifications, resulting in an inability to withstand the working load. For example, in the building construction project at Wonderland Uluwatu, the planned concrete quality for the cantilever beam was K300. However, when the hammer test was conducted at 28 days of curing, the expected quality was not achieved. So, a cantilever beam is necessary to repair and strengthen the concrete structure of the building to ensure its safety. This research compares the reinforcement methods for cantilever beams in terms of cost. Two cantilever beam reinforcement methods will be implemented: first, steel jacketing reinforcement using 8 mm and 10 mm thick steel plates; second, IWF steel reinforcement with dimensions of 500 mm x 200 mm x 10 mm x 16 mm. These reinforcement methods will be evaluated through deflection analysis and deviation analysis. The results of this study indicate that the cost of the steel jacketing reinforcement method with thicknesses of 8 mm and 10 mm amounts to Rp. 345,086,768.00. In contrast, repairing or reinforcing the cantilever beam using the IWF 500.200.10.16 steel method, assuming that the IWF is available in Bali, costs Rp. 272,515,956.00. Based on the cost calculations for each reinforcement method, it can be concluded that the IWF steel method is more economical, with a difference of Rp. 72,570,812.00.

The Bangli Regency Public Service Mall Building was built on 2 floors with a conventional concrete structure. To ensure timely completion, accelerating structural work is important. One effort to speed up the implementation time is to speed up the dismantling of the anchors on the 2nd floor beam and slab elements so that the structural work time will be reduced and the work costs will also be reduced. Based on this, the author raised the title "Analysis of the Effect of Steger Demolition Age on Concrete Quality and Its Implications for Cost and Time (Case Study: Bangli Regency Public Service Mall Project)". This research aims to find out at what age the dismantling of the studs can be carried out so that the concrete is able to accept the load that is working at that time and its effect on time and costs. The building structure is a very important element because it plays a major role in providing strength, stability, and resistance to the loads received by the building. To determine when the stem can be opened and the concrete is able to withstand the load when the stem is opened, a structural analysis using SAP 2000 is needed based on the age of the concrete. This analysis was carried out at concrete ages of 3, 7, and 14 days. The results of the analysis show that the concrete can accept the load when the stem is opened when the concrete is 7 days old. From the time the structural work plan was reviewed, it was 84 days after acceleration to 63 days. Meanwhile, the difference between the plan cost and the cost of the analysis results is IDR 108.036.407, or 7.66%.

Rizky Pradipta — 2024-12-30

Delays in the project are very important because they can affect the profits that the contractor gets. If there is an unwanted delay in the project, the contractor can be fined in the form of a financial penalty that affects the profit obtained by the contractor. If this happens, the contractor will look for solutions to accelerate to catch up with the existing lag so that delays can be anticipated. One of the ways contractors use to catch up due to project delays is by crashing. This study uses a mixed approach. The data used is data obtained directly from the project by conducting interviews directly with project staff and also requesting project data. The result of this study is that 9 factors were obtained that caused delays that occurred in the Lira Medika Hospital construction project, Badung. As for the acceleration using the crash method, the most optimal result was obtained by increasing the workforce, which reduced the project duration by 84 days (project completion time to 209 days) at an additional cost of Rp 29,782,500.00. Meanwhile, by increasing working hours (overtime), the project duration was reduced by 81 days (project completion time to 212 days) at an additional cost of Rp 117.140.625,00.

In The implementation of building construction projects often involves discrepancies between the actual conditions on site and the planned results, leading to the issuance of change orders or CCO (Contract Change Order). The occurrence of CCO in construction projects impacts both the time and cost of project implementation. This research aims to analyze the extent of the impact of Contract Change Order (CCO) on contract value and project duration, and to identify the factors causing Contract Change Order (CCO). The research method used combines both qualitative and quantitative data (mixed methods). The analysis results show that Contract Change Order (CCO) in phases I and II did not alter the contract value. However, CCO in phase III changed the contract value from IDR 70,231,000,000.00 to IDR 72,054,210,000.00, representing a 2.60% increase.The project duration remains unchanged at 30 weeks or 210 days despite the Contract Change Order (CCO). The factors causing Contract Change Order (CCO) include additions and reductions in the scope of work items, discrepancies between drawings and actual site conditions, the addition of new work items, and changes in building design.

The construction industry in Indonesia has been rapidly advancing. The design and build method is one form of innovation in construction work that speeds up infrastructure development. However, this method also leads to changes in design, materials, and other aspects during the execution of work, which can result in construction management failures. This study analyzes the impact of changes in architectural design plans on other work, the effect of changes in architectural design plans on time, and measures that can be taken to control project delays. The research uses a descriptive quantitative method with the Microsoft Project application to create project scheduling according to the planned time schedule and the addendum time schedule, to identify work items that experience changes and the addition of work duration. The results show that changes in architectural design plans affect changes in wall work, ceiling work, door and window installation work, sink work, wall panel work, and painting work. It also impacts the critical nature of architectural work, mechanical, electrical, and plumbing (MEP) work, and interior work, leading to an increase in the duration of architectural work from 307 days to 706 days, meaning an increase of 399 days from the initial plan. The most effective measure recommended to address delays is to increase the workforce to enhance the completion rate of work daily.
