Abstract

The need for clean water in Wonosalam District increases every year as seen from data from the Demak Regency Central Statistics Agency, where the population of Wonosalam District from 2018 to 2022 has increased, so the need for water is also increasing. Therefore, the aim of this research is to determine water needs, water availability, quantity and quality of water and determine the capacity of the reservoir to accommodate clean water. Starting with collecting secondary data, namely population data, data on the number of PDAM customers, source capacity and discharge data, water quality samples. In calculating population growth, population data for the last 5 years is used with predicted calculations until 2032. To calculate this data, the Geometry method, Arithmetic method, and Linear Regression method are used. Then from these calculations, the Arithmetic method was chosen because it has a smaller value. Based on data calculations using the arithmetic method, the value of clean water needs from the population calculation in 2031 is 149,251 liters/second. Meanwhile, the need for clean water for the number of PDAM customers in 2032 is 7,176 liters/second. For the availability of clean water from a source capacity of 10 liters/second and a production discharge of 7,176 liters/second.

Abstract

The construction of the Simpang Joglo Elevated Track Bridge is an iconic development in the city of Surakarta with the Elevated Railway Bridge which was built over seven very busy intersections. At this intersection, traffic jams often occur when trains pass, for this reason an elevated track railway bridge was built to reduce this congestion. The implementation of development is not free from risks that occur both internally and externally. This research aims to identify the risks and problems that occur in the construction of the Simpang Joglo Elevated Track Bridge. After identification, an assessment will be carried out on the level of risk that has been identified in the construction of the elevated track bridge at Joglo intersection. Data collection was divided into two, namely primary data collection through distributing questionnaires and interviews on the Simpang Joglo Elevated Track Bridge Construction Project which was conducted with project owners, consultants and contractors and secondary data collection through previous research and data from the Simpang Joglo Elevated Track Bridge Construction Project. Risk identification is carried out using the Risk Breakdown Structure (RBS) method and probability impact grid to determine the level of risk. After obtaining the data, a feasibility test will be carried out on respondents and then a validity and reliability test will be carried out for the three stakeholders. Risk identification is carried out by calculating the probability and impact for each variable and then clarifying the ranking using the Extremely Ineffective, Ineffective, Moderately Ineffective, Very Effective and Extremely Effective rating scale. After that, the risk level is classified using a probability-impact matrix. From the results of the risk level classification, it was found that there were 31 risk variables in the high category from the owner, 31 risk variables according to the consultant and 19 risk variables according to the contractor. Determining the high category of risk is based on combining the same variables from the three stakeholders to obtain 18 risk variables. These variables are problems that occur and influence the implementation of the Simpang Joglo Elevated Track Bridge Construction Project. These problems include increased vibration, traffic flow, road damage, K3 environmental sanitation, community attitudes and perceptions, organizational structure, payments, owner finances, overtime, time and cost estimates, changes in design, heavy equipment and materials

Abstract

Ulo Secondary Canal which has an irrigation area of 1,352 ha is one of the secondary canals in the Madiun Main Canal. Ulo Secondary Canal is supplied by three dams namely Semawur Dam, Jati Dam and Gondrok Dam which are located in Madiun Regency. The Madiun Main Canal Irrigation Area has been rehabilitated in 2019, and has been completed in 2022. The Madiun Main Irrigation Channel area is still in need of water. The methods used to calculate water requirements are Climatology Method, FJ. Mock Method, and Water Balance Method. From the calculation, it is known that the condition before rehabilitation, the value of water availability cannot fulfill agricultural water needs in the Ulo Secondary Canal area. In conditions before rehabilitation, the supply from Jati Dam is 18% with a value between 0.43 m3/s - 0.72 m3/s, coupled with water withdrawal at the Semawur Dam intake of 0.06 m3/s and water withdrawal at the Gondrok Dam intake of 0.07 m3/s. The existing water availability can only fulfill the needs of the cropping pattern of paddy (20%) - crops (40%) - crops (45%), with the smallest residual discharge value of 0.09 m3/s in April III. After rehabilitation, the supply value of Jati Dam is 15% with a value between 2.17 m3/s - 2.72 m3/s, with water withdrawal at the Semawur Dam intake of 0.06 m3/s and water withdrawal at the Gondrok Dam intake of 0.07 m3/s.The percentage value after rehabilitation is smaller than before rehabilitation but the value of water supply is bigger. Based on these conditions, several alternative cropping patterns are planned, such as Paddy (100%) - Crops (100%) - Crops (100%), Paddy (100%) - Paddy (100%) - Crops (100%) and Paddy (100%) - Paddy (100%) - Paddy (100%) with a profit amounting to IDR 6,415,515,780.00 in conditions before rehabilitation and after rehabilitation, on alternative III with a cropping pattern of paddy (100%) - paddy (100%) - paddy (100%) obtained the highest profit amounting to IDR 62,144,490,720.00.

Abstract

The high mobility of the people and traffic due to the existence of a railroad crossing on the Mranggen road section is the main factor for the high congestion that exists on this section. The government's efforts through the Central Java Office of Public Works and Human Settlements to build the Ganefo Mranggen KM 14 Fly Over is an alternative solution to tackling the high traffic jams on this section. Therefore, researchers will identify how the performance of the Mranggen road section after the construction of the Fly Over. After conducting research, it was found that the busiest traffic was on Wednesday at 16.00-16.15 with a total flow value of 883.3 pcu/hour. The degree of saturation is 0.962 0.75, which exceeds the requirements of the 1997 MKJI guidelines. If the value of the degree of saturation 0.75 requires improvement, then the degree of saturation is included in the category E service level with conditions of very high traffic density and low volume. The highest side resistance value on this section is 906.8 where the time interval is 06.00-09.00 WIB with the VH Resistance Class (906.8 900) which means commercial area, with roadside market activity. So that alternative solutions can be found using SWOT calculations where it is known that the segment is in a position between the Weakness and Opportunity axes, namely in quadrant 4. This means that the Ganefo Mranggen Fly Over segment is advised to change the strategy from internal Weaknesses So that the strategy is changed to Opportunity ( external Opportunity) in order to achieve good traffic performance on the Ganefo Mranggen Km 14 Fly Over section.

Abstract

The development of construction planning, especially in the construction of building structures, calculates unit prices using a tool called Construction Cost Analysis (ABK), where until now the method often used by contractors and consultants is the BOW (Burgerlijke Openbare Werken) guideline. However, as time went by, it was realized that the BOW guidelines were only segmentally suitable for projects in the form of labor-intensive work that utilized conventional equipment and less professional workforce, which resulted in very expensive planning costs if this approach was still used purely. The 2008 Indonesian National Standard (SNI) analysis method is an update of the 1921 BOW (Burgerlijke Openbare Werken) analysis during the Dutch government, in other words, the SNI analysis is an updated BOW analysis. This SNI analysis was issued by the Center for Settlement Research and Development. The cost preparation system using SNI analysis is almost the same as the calculation system using BOW analysis. The basic principle of the SNI method is that a list of coefficients for materials and labor costs has been determined to analyze the price or costs required to make a unit price for building work. From these two coefficients we will get a calculation of the materials needed and a calculation of the wages of those doing the work. The comparative composition and arrangement of materials and labor for one job has been determined, which is then multiplied by the price of materials and wages prevailing in the market.

Abstract

Silica contains impurities that are carried during the sedimentation process. Silica is usually obtained through a mining process that starts from mining quartz sand as a raw material. This study aims to determine the effect of fine aggregate of Malimpung silica sand on the compressive strength of concrete. And to determine the effect of fine aggregate of Saddang river sand on the compressive strength of concrete. In this study, tests were conducted on two types of fine aggregates to determine their effect on the compressive strength of concrete. The research method used is a quantitative experimental method with compressive strength testing at the ages of 7, 14, and 28 days. The results of the study obtained showed that concrete using Malimpung silica sand had a higher compressive strength compared to concrete using Saddang river sand. At the age of 28 days, the compressive strength of concrete with a composition of 100% silica sand reached 28.120 MPa, while concrete with 100% river sand only reached 19.439 MPa.
