Abstract

The Landak Sub Watershed is part of Indonesia's Kapuas River Basin, covering an area of approximately 7,921 km2 and comprising three administrative regions: Landak Regency, Kubu Raya Regency, and Pontianak City. Like other regions in Indonesia, the frequency of flood events in the Landak Sub Watershed has been increasing each year, becoming a severe problem as it has caused losses for the community. Therefore, a study is needed to provide an overview of the most suitable flood management measures to minimize floods in the Landak Sub Watershed.This article presents the research results to determine the priority scale of flood mitigation measures suitable for implementation in the Landak Sub Watershed using the Analytic Hierarchy Process (AHP). The determination of criteria, sub-criteria, and flood management alternatives is based on the results of a Focus Group Discussion (FGD) held in Ngabang City on August 30, 2022. The selected flood management alternatives combine both structural and non-structural measures. Once the hierarchy is established, a questionnaire is distributed to determine the appropriate options for flood mitigation in the Landak Sub Watershed.The study results indicate that the priority scale for flood mitigation in the Landak Sub Watershed is by revising regulations and policies. The analysis shows that the priority criterion is Law and Institutions with a weight of 0.376, the priority sub-criterion is Legislation with a weight of 0.213, and the priority alternative is the revision of regulations and policies with a weight of 0.1984. For the correction of rules and procedures to be effectively carried out, all stakeholders related to flood control in the Landak Sub Watershed must be involved.

Abstract

Roads are infrastructure that has a vital role for the community in supporting social and economic activities. Therefore, appropriate handling information is needed for road maintenance and improvement to be on target. One of the methods used is the International Roughness Index (IRI) method with the help of the Road bump application. The purpose of this study is to analyze and recommend handling road surface conditions, as well as to test the validity of the Road bump application with a Laser Profilometer. This research was conducted on the 10 KM section of Trans Kalimantan Road. Comparative data is obtained from secondary data issued by BPJN in 2021 using the Laser Profilometer tool. This study found that the condition of the Trans Kalimantan Road was 80% in the excellent category, 18% in the moderate category, and 2% in the slightly damaged category, and had similarities with the BPJN IRI value of 95%. Road bump also tends to the IRI value to be greater than the BPJN IRI value. Based on the results of this study, the Road bump application can be used as an alternative tool for measuring road surface conditions using the International Roughness Index (IRI) method.

Abstract

In a construction project, the productivity of the workforce is one of the fundamental factors that plays an important role in the project's success. Lower productivity increases the likelihood of work delays, whereas higher productivity reduces the chances of delays. The purpose of this study is to determine the productivity levels, labour coefficients, and productivity levels based on Labour Utilization Rate (LUR) for the beam and floor slab work in the Myze Sumenep Hotel Project. The method used in this study involved observation and work sampling methods, employing a productivity rating approach. The research findings indicate that the formwork work group has the highest productivity level in the field, with an average of 5,118 m2/person. The productivity levels for beam iron work, plate iron work, and casting work are 86,461 kg/person, 245,064 kg/person, and 7,364 m3/person, respectively. The work calm coefficient for formwork work is found to be 0,019 OH for foremen, 0,096 OH for builders, and 0,096 OH for workers. For beam iron work, the coefficients are 0,001 OH for foremen, 0,005 OH for carpenters, and 0,005 OH for workers. The coefficients for plate iron work are 0,005 OH for foremen, 0,002 OH for carpenters, and 0,002 OH for workers. Finally, for casting work, the coefficients are 0,014 OH for foremen, 0,041 OH for builders, and 0,081 OH for workers. Based on the worker utility factor (LUR) for beam and slab formwork, the average LUR productivity is 82,84%. Beam ironing work has an average LUR of 86,75%, plate iron work has an average LUR of 86,83%, and foundry work has an average LUR of 69,59%. Therefore, the productivity levels are deemed satisfactory as they exceeded 50%.

Abstract

Global climate change is expected to cause an increase in the intensity and duration of extreme rainfall events that occur today. The leading cause of flooding in various world regions, including flat coastal areas such as the Serok River catchment in Kota Pontianak, influenced by tides, is excessive rainfall. This article presents the results of an analysis of the impact of extreme precipitation on the peak discharge of flood hydrographs in the Serok River catchment, Kota Pontianak.Maximum daily rainfall data for 2009-2020 recorded at PTK-11 Pontianak Station were selected using the Annual Maximum Series Method. Frequency analysis was conducted using the best distribution method selected from Normal, Log Normal, Log Pearson Type III, and Gumbel Type I to obtain the design rainfall. The design rainfall was transformed into flood hydrographs at the next stage using the Snyder Synthetic Unit Hydrograph based on several return periods.The results of the analysis show that there are changes in flood discharge in the Serok River catchment area for each return period. The location of land use and the value of rain intensity significantly affect the calculation of plan discharge; the more significant the land area and the higher the rain intensity, the greater the resulting release. The most considerable flood discharge (Qmax) in the 2, 5, and 10 years return occurs at STA 1 + 100, w.290 m3/s, 0.347 m3/s, and 0.377 m3/s, respectively. Thus, this causes periodic flooding/inundation conditions, especially in areas that have low elevations.

Abstract

Floods are common natural catastrophes in Indonesia, particularly during the rainy season. The Parit Berkat water catchment region is one of the locations that frequently experience flooding. The channel's capacity must be increased to accommodate the current water discharge, resulting in this condition. Several reasons are responsible for the diminished capacity of the canal. For instance, inhabitants' activities along canal banks might contribute to the siltation of channels. This research aimed to evaluate the influence of tides and rainfall on the flow of the Parit Berkat Canal. This research provided the use of both primary and secondary data. The leading information consists of measurements of the cross-section and length of the channel and the elevation of the tidal water level over 15 days. Secondary data consists of the maximum daily rainfall data received from Balai Wilayah Sungai Kalimantan I (BWSK I) and the location map for the research. The flow profile is simulated using HEC-RAS. The findings demonstrate that when maximum rainfall and low tides coincide, 13 stations are safe in the 2-year return period of rain, eight stations are safe in the 5-year return period, and six stations are safe in the 10-year return period.

Abstract

Heavy equipment is a vital resource in a project, but renting heavy equipment is a costly undertaking. Besides that, a project always has constraints that allow the project completion time to exceed the specified time, and delays will also cause costs incurred to increase. So from the calculation of the productivity of heavy equipment, it is necessary so that the tool can work optimally. From the analysis results, it was found that the productivity of excavators was 154.185 m3/Hour. For dump trucks, it was 37.99 m3/Hour, then calculating the duration of work. For heavy equipment excavators, it took 454 Hours, and for dump trucks, it took 263 O'clock. For the cost of renting heavy equipment from the calculation of the analysis of the cost of renting heavy equipment for excavators, a value of Rp.1,985,200/Day is obtained, while for dump trucks, it is Rp.2,578,000/Day

Abstract

Many rain-to-discharge transformation models have been made, such as the Mock Model and the NRECA Model, which are used to make monthly synthetic discharge data when there is not enough discharge data to analyze water availability in a Sub-Basin or Sub-Basin. Tropical Rainfall Measuring Mission (TRMM) data, created by NASA and JAXA, is one type of satellite-based rainfall data that can help overcome the lack of rainfall data. However, not all areas have rainfall recording stations, and if there are, not all existing rainfall recording stations operate correctly. Such conditions also occur in the Melawi Sub-Basin in West Kalimantan. This research aims to determine how much water is available in the Melawi Sub-Basin by putting satellite-based rainfall data into the NRECA model and the Mock model, which converts rainfall to discharge.This study was done to determine how reliable TRMM satellite rainfall data are as input data for the rainfall-to-discharge transformation model used to determine how much water is available in the Melawi Sub-Basin. The goal of this study is to assess the suitability of TRMM data with observation station rainfall data in the Melawi Sub-Basin by validating TRMM satellite rainfall data with BMKG Susilo and BMKG Nanga Pinoh observation station rainfall data and to choose the appropriate rain-to-flow diversion model used in the Melawi Sub-Basin based on the results of model parameter calibration, with the models whose parameters are calibrated being the Mock Model and the NRECA.The study results show that TRMM rainfall data in the Melawi Sub-Basin that has been validated and corrected with the equation Y = 0.748089283 X + 62.19135368 can be used as input data in the analysis of water availability, and the transformation model of rainfall into discharge that is more suitable is the Mock Model. In general, both the observation station rainfall pattern and the TRMM rainfall pattern tend to have the same pattern as the discharge pattern in the Melawi Sub-Basin. The fact that August has the lowest peak is clear evidence of this. Even though the highest point doesn't happen in the same month, the trend is the same, so TRMM rainfall data can be considered valid and used to replace observational rainfall data in the Melawi Sub-Basin. Similar research can be done on other Sub-Basins in Kalimantan Barat Province to help develop and manage water resources since many observation stations in Kalimantan Barat Province no longer work, and there are many large Sub-Basins in that province.
