Abstract

In one of the smelter projects at West Kalimantan, access road construction was planned to use soil embankment above the geo-membrane layer. But this method is not highly effective considering rainfall intensity is very high in the project location. Therefore, optimization needs to be done to obtain the most effective method in terms of cost and timely accomplishment of the access road. The optimization method is done by making a comparison matrix of the output results of the running simulation schedule on software. From the several methods proposed, the duration of completion, completion costs, and resource requirements are compared and scored to get the most optimized method. Other than that, carbon emissions resulting from each method are also compared. The optimization result concluded that boulder stone layer addition with optimum quantity in the embankment is the most optimal method considering the remaining time and encountering intensive rainfall. This optimized method can result in an accelerated construction duration of 140 days, cost efficiency of 11.46%, and a reduction in carbon emissions of 44% compared to the initial method. This optimization method is expected can be applied to access road embankment projects of soft soil areas in other locations, especially in the Kalimantan region.

Abstract

POFA (palm oil fuel ash) and seawater have the possible to be used in concrete as an effort to reduce construction costs and environmental waste problems. POFA contains pozzolanic properties such as those contained in cement so it has the possible to be used as a mineral in concrete mixtures. Therefore, the use of POFA and seawater in concrete mixtures have the potential to be implemented, but it is obligatory to pay awareness to the potential for corrosion that also follows. This study aims to evaluate the use of POFA up to 20% as a replacement for cement and the effect of mixing seawater on the strength and corrosion of reinforcing bar in concrete. The compressive strength of concrete was evaluated by carrying out a compressive test on a cylindrical specimen with 100 mm in diameter and 200 mm in height at 7 days and 28 days of age. Furthermore, a concrete cylinder specimen with a diameter of 10 mm reinforcement was used to evaluate the potential for corrosion. Measurement of corrosion estimation using the half-cell potential (HCP) method based on ASTM C876-15. Test results show the use of up to 10% POFA to replace cement by mixing seawater and treated with fresh water has a high strength that is almost the same as normal concrete. The risk of corrosion is also not detected and proven by actual measurements of corrosion. Furthermore, HCP values more negative than -400 mV are predicted to experience corrosion in the reinforcement area above 10%.

Abstract

Construction industry is a labor-intensive sector that absorbs a large number of workers. Therefore, the industry must be able to pay attention to human resources which are a valuable asset. One of them is related to the mental health of construction workers. Even though the construction industry is known for its stressful environment, not much research has been conducted regarding the fulfillment of mental health aspects of construction workers, especially in Indonesia. In fact, various mental health disorders such as depression and anxiety can have an impact on the performance of construction workers and industry. This research aims to identify various factors related to mental health that influence construction workers through an integrative literature study. The results of the analysis succeeded in finding 68 factors related to mental health in the construction industry which were grouped into four domains, namely types, causes, impacts and solutions to overcome mental health disorders in the construction industry. Identification of these factors and domains is important as a means of understanding mental health aspects so that they can become a reference for stakeholders, especially the government and construction project organizations, in an effort to increase awareness on the importance of mental health in the construction work environment. In this way, the government and construction project organizations can be proactively involved in realizing the achievement of sustainable development goals, namely good health and well-being.

Abstract

The Ulee Lheue Ferry Port connects Banda Aceh City to Sabang City. Passenger services at the port are expected to meet the established service standards to enhance Sabang City tourism and mobility for local residents. The purpose of this study is to evaluate the performance of facilities and services at the Ulee Lheue Ferry Port based on passenger assessment. This study employs a quantitative descriptive method, with a questionnaire instrument delivered to 400 respondents using simple random sampling. Respondents should meet the following criteria: must have used port facilities and services in 2023; be over 22 years old; and have a job and income. The Importance Performance Analysis (IPA) method was used to analyse the data. By referring to the service quality (servqual) aspect, 46 indicators are utilized to measure the level of performance and its importance. The findings revealed, only 9 indicators were included in the highest priority (quadrant A), implying low performance but essential problems. Those indicators are health facilities, security facilities, bathroom conditions, service information, officers' concern, officers' responses, officers' reactions to passengers’ problems, officers' friendliness, and officers' service equality. In conclusion, this study suggests that port management and local government should improve facilities and services so that passenger service standards at Ulee Lheue Port would be significantly better.

Abstract

Water loss that occurred in the service area of the Pleret 1 Reservoir managed by PDAM Pasuruan City from January to November was 42.92%. The highest water loss occurred in January of 46.85% and the lowest in May of 33.43%. This is still very far from the standard 20%. The current condition of the Pasuruan City PDAM distribution pipeline network is that all systems are connected to each other, so that there are no separate systems. Efforts that can be made by PDAM Kota Pasuruan to reduce water loss and interconnection networks are to isolate the piping network by establishing a DMA (District Area Meter). Formation of DMA requires hydrolysis modeling simulation of distribution pipeline network using Epanet 2.2 software. Besides using Epanet 2.2 software, Quantum GIS 3.16.16 software is needed to create a pipeline. The validity test in the field uses the discharge parameter with a correlation coefficient between EPANET and field discharge data obtained at 0.61. The formation of DMA with good results to reduce air loss is by reducing air pressure, if the air pressure decreases, the air loss will be lower.

Abstract

Sepaku Semoi Reservoir is located in Tengin Baru Village, Sepaku District, North Penajam Paser Regency, East Kalimantan Province, and has a water catchment area of 70.19 km2. This research aims to determine the amount of flow discharge entering the Sepaku Semoi Reservoir Catchment Area using the Mock Method. The rain data used is GPM satellite data as an alternative to the unavailability of rain recording posts in the Sepaku Semoi Reservoir Water Catchment Area. GPM satellite data needs to be calibrated and validated against rain recording posts in the field to determine the accuracy of the data. The highest GPM satellite data calibration is the Intercept linear regression equation with a value of R2 = 0.852. The best validation of GPM satellite data was shown in the 2004 period with a value of RMSE=65.04; KR=13%; R=0.91. The annual average maximum discharge is 6.26 m3/sec and the minimum is 3.17 m3/sec. Validation of the Mock Method flow rate is shown with a value of NSE=0.78; R=0.79. Based on the results of the analysis that has been carried out, concluded that an alternative in predicting observed discharge data in the field can be done using the Mock Method based on GPM satellite data.

Abstract

Some researcher missed the role of hooks in their bamboo reinforcement. Consequently, the bamboo reinforcement and concrete used to have slip and failure to composited, this make the concrete and bamboo working independently to sustain the given loading and the bond failure become the main issue than the beam failure. This research studied about the role of the pivot hooks that capable to enhance the loading capacity higher than the beams without the pivot hooks. Experimental test performed in order to identify the effect of the pivot hooks presence which added to the flexural reinforcement which made by bamboo materials to avoid the bond slip failure that mostly occur in the bamboo reinforced concrete beams. The experimental test which verified by the numerical analysis by FEA NX commercial software proof that the pivot hooks are able to increase the loading capacity of a concrete beam 33% - 40% higher than the bamboo reinforcement without the pivot hooks. Architectural façade and budget efficiency caused the bamboo become unavoidable material in construction, by adding the structure modification such as the pivot hooks for the bamboo reinforcement, the failure can be reduced, then the entanglement of bamboo in construction become more functional.

Abstract

Climate change and geographic location affect water availability. Coastal areas in Indonesia generally have drinking water problems because the well water is dry due to the dry season and the water is brackish, as is the case in Sawojajar Village in Brebes Regency, Central Java. On the other hand, the potential for rainwater in Sawojajar Village is quite good. The Brebes Regency Government is planning and implementing a rain harvesting (Gama Rain Filter) with an individual type for people who want to install rainwater harvestings in their homes, and a communal type for people who still want communal rainwater harvestings. This applied research aims to compare the two types. The individual type planning method for harvesting rain is carried out in each house and the communal type planning method is carried out in groups of houses. The planning carried out includes checking the quality and quantity of rainwater, calculating the dimensions of the storage tank, design drawings, and planning and implementation budget plans. The results of this applied research are the quality and quantity of rainwater, the design of individual and communal type rainwater harvestings, and the planning costs and implementation costs required. This research resulted in the conclusion that the individual type rain harvesting is more recommended than the communal type because the individual type costs less to plan and construct, is more flexible in placement, easier to manufacture, and maintains operations more securely.

Abstract

The Aesesa watershed is the largest watershed in the Flores River Basin located in Ngada Regency and Nagekeo Regency, with a watershed area of 1,169.24 km2 and a main river length of 66.92 km. The Aesesa watershed consists of 13 sub-watersheds with varying shapes and complex characteristics. This makes the Aesesa watershed potentially prone to flooding. The purpose of this study is to identify the potential for flooding from sub-watersheds in the Aesesa watershed using the Cendana method. The data used include morphometry data, watersheds, and maps. In using the Cendana method, the input parameters taken into account are watershed area (A), main river length (L), annual maximum daily rainfall, watershed shape, river density (D), river slope (s), Nakayasu α value, channel roughness (n), curve number value (CN), and land cover. Then from the calculation of the data, value weighting will be carried out to identify flood vulnerability. The results of this study show that the weighting for 13 sub-watersheds in the Aesesa watershed is on average in the high category with a range value of 2.30 – 2.70. From this result, it is expected that mitigation and adjustment efforts can be made, especially in sub-watersheds that are already high with a weight value of 2.70 to reduce the magnitude of losses due to flooding.

Abstract

Infrastructure development is crucial to the development of a nation’s economy. Based on data from the 2021 World Competitiveness Yearbook, Indonesia's infrastructure is ranked 57th out of 64 countries and one of the assessment criteria is related to water resources. Water resource management in Indonesia is still faced with fundamental challenges, including the limited water storage capacity in Indonesia so alternative water resources development is needed, among which is through the construction of dams. In practice, dam projects are very vulnerable to time delays. One of the solutions to this problem is the application of the last planner system method. The implementation of the last planner system can help create major improvements in project planning, increase workflow and productivity, and reduce project time and site accidents. This research has an update regarding the implementation of the last planner system method on a dam project and analyzing the key success factors using SEM-PLS. According to the study's findings, the key success factors of the implementation of the last planner system method on dam projects are budget plan, work schedule, clarity of scope of work, work plan, planning process, and weekly plan
