Abstract

Concrete Mix Design is the design of concrete using concrete constituent materials consisting of fine aggregate (sand), coarse aggregate (gravel), cement, water with added or not added ingredients, with the aim of obtaining the compressive strength of the planned concrete. One indicator of good concrete quality can be seen from the results of compressive strength testing, where the compressive strength of the resulting concrete must not be lower than the compressive strength of the planned concrete in the mix design. Mix design work must be carried out carefully and carefully because when determining the ratio and proportion of the concrete mixture you must pay attention to good concrete standards and meet the requirements, including compressive strength, workability (ease of work) and durability (concrete durability). The aim of this research is to find out what factors influence the compressive strength of normal concrete to be lower than the compressive strength of the planned concrete in the mix design, and to find out the difference between the compressive strength of the resulting normal concrete and the compressive strength of the planned concrete. The large number of concrete compressive strength results that do not match the strength of the mix design plan in many studies of Civil Engineering students at Islamic University 45 Bekasi is the basis for the need to carry out analysis so that the cause of the error can be identified, starting from filling in the mix design form, determining the ratio from the graph, the proportion of the mixture of the constituent materials. concrete, as well as the ratio of weight or volume of concrete used. The results of this research show that the compressive strength planned in the mix design was 20 Mpa, while the average compressive strength produced with a W/C of 0.59 was 17.5 Mpa, which decreased by 12.5%, while the average compressive strength produced with a W/C of 0.6 amounting to 22,667 Mpa, an increase of 13.3% from the design compressive strength, possibly because the water content is greater so it is easier to mold, so the concrete surface is flatter and the resulting compressive strength is greater. W/C is the ratio or comparison of the weight of water to the weight of cement and cementitious additives which are generally added to high quality concrete mixtures. The conclusion is that the factors that influence the compressive strength of normal concrete to be lower than the compressive strength of the planned concrete in the mix design are sand with a fine modulus of 3.0635, gravel with a fine modulus of 6.72. The average concrete compressive strength for W/C 0.59 is 17.5Mpa and the average concrete compressive strength for W/C 0.60 is 22,667 Mpa, so the difference between the two average compressive strengths is 5.2 Mpa, where with W/C 0.60 The resulting compressive strength of the concrete is better.

Abstract

A lack of public understanding regarding corrosion prevention has led to significant damage to iron-based objects due to corrosion. Therefore, preventive measures are necessary, including the utilization of used oil. Certain types of oil have been formulated with additives that can effectively prevent corrosion in metal components, particularly in machinery. This community service program aims to educate the public on how to prevent iron corrosion and conduct maintenance using readily available materials, especially used oil. When applied to iron surfaces, oil forms a protective layer that prevents oxidation and other forms of degradation. Lubrication with used oil has proven to be highly effective in corrosion prevention, as oil contains anti-corrosion properties that protect coated surfaces from rust. This community service activity was carried out in Karang Indah Village, Bojongmangu District, Bekasi Regency, with the objective of training the community to become more aware of the importance of maintaining cleanliness and preserving village infrastructure. The results of the training on iron corrosion prevention and maintenance using used oil demonstrated a positive impact, enhancing the community’s understanding of the dangers of corrosion and the importance of preventive measures to ensure the durability of iron-based objects. Through interactive socialization and training sessions, residents gained new insights into various corrosion protection methods, including the application of used oil, breadfruit leaf extract, anti-rust coatings, painting, and other maintenance techniques.

Abstract

The Sadang River is a primary channel in Cibitung Subdistrict, Bekasi Regency, which functions to channel water from several secondary channels, including those in Wanajaya Village and Wanasari Village. The existing conditions show that the Sadang River is prone to overflowing during the rainy season and is unable to optimally support the irrigation needs of the surrounding agricultural land. Therefore, a redesign of the channel system is necessary, including increasing the river's storage capacity through channel dimension improvements based on peak flow rates derived from hydrological analysis, as well as integrated watershed management efforts. The objective of this study is to analyse the river flow discharge in the Sadang River, which is divided into four segments, and to address the river flow discharge. The research method used in this study is a quantitative method with a hydrological and hydraulic analysis approach. The hydrological analysis process was carried out by determining the average rainfall and analysing the flood discharge using the Nakayasu Synthetic Unit Hydrograph (HSS) method. Subsequently, measurements of the existing channel dimensions were taken, spatial analysis was conducted using ArcMap 10.8 software, and the channel dimensions were re-planned based on the planned peak discharge results. The research results show that the existing flow rate of the Sadang River is 954.37 m3/sec, and the analysis of the peak flow rate of the Sadang River with a 10-year return period is 6107.47 m3/sec and a 25-year return period is 7513.01 m3/sec, with the same peak time of 2 hours. It is necessary to plan with a rectangular channel, the dimensions of the channel base width (b) = 28.7m and channel height (h) = 10m because the river channel is unable to accommodate the flow of flood discharge.

Abstract

The Cost Budget Plan (RAB) is one of the main processes in a project because it is the basis for making a financing system offer and the budget framework that will be issued. The Cost Budget Plan (RAB) is needed to calculate a building or project with the amount of costs required for materials, wages and other costs related to building implementation. The Student Dormitory Building Construction Work Package in Bintaro was announced on the LPSE website of the Ministry of Finance. The Dormitory Building stands on a total land area of ±212,222m². Meanwhile, what will be built as a Student Dormitory building with a design area of ±3,647m² with a total of 8 Dormitory floors. From the calculation results, it is known that the recapitulation of the Cost Budget Plan (RAB) is Rp. 67,619,783,891 including 12% VAT with the largest work value being on the 2nd floor structure work with a value of Rp. 7,309,075,651. The advantage of e-Procurement is that it is very helpful for construction service providers to participate in each selection stage because it is not limited by distance and all processes are carried out online. However, in practice, this e-procurement system still relies on offline face-to-face meetings, such as the Aanwijzing stage, and is often found in the final negotiation stage. This can raise suspicion among every tender participant

Abstract

The preparation of the Bill of Quantity (BoQ) or Cost Budget Plan (Rencana Anggaran Biaya/RAB) is one of the crucial stages in the construction project planning process, which must be carried out before the physical implementation of the project begins. The RAB reflects a comprehensive cost estimate required for a project, covering both labor wages and material procurement. This document contains detailed information on the volume of work, unit prices, and total costs for each component necessary for the realization of the project. One of the commonly used approaches for preparing RAB in Indonesia is the Unit Price Analysis Method (Analisa Harga Satuan Pekerjaan/AHSP). This method is considered capable of producing efficient and accountable cost estimates in accordance with applicable national standards. This study aims to identify economical unit price estimations that can serve as a reference for cost estimators in planning construction project budgets. The research adopts a quantitative approach by analyzing data through volume calculations based on technical drawings, followed by the application of the AHSP 2023 method to determine unit prices, and organizing the results into a BoQ format using Microsoft Excel. The findings indicate that the total estimated cost for the structural development of the State College of Accountancy (Politeknik Keuangan Negara STAN) Mosque in Tangerang is IDR 10,935,996,000.00, which includes all components of work ranging from land excavation, foundation work, and structures for floors 1 to 3, to roof construction, as well as the foundation and structure of the mosque tower. The total cost already includes a contractor's profit margin of 10% and taxes (VAT and Income Tax) of 10%. The largest portion of the budget is allocated to the structure of the first floor, accounting for 23% of the total budget. These findings emphasize the importance of accurate planning in the early stages of a project to minimize potential financial risks in subsequent phases.

Abstract

Processing of coconut shells into charcoal powder as a concrete mixture. The use of coconut shell charcoal powder on the compressive strength of concrete aims to be a substitute for cement for normal concrete compressive strength and to determine the optimum concrete compressive strength after substitution of cement using coconut shell charcoal powder. In this study the use of coconut shell charcoal powder as a cement substitution with variations of 0%, 2.5%, 5% and 7.5%. Concrete testing was carried out at the age of 28 days after treatment by being immersed in water. The results of the analysis showed that the average compressive strength value of the addition of coconut shell charcoal powder at variations of 5% and 7.5% decreased by 11% and 12.57% because with the increasing number of calcium hydroxide formed, the cement adhesion will decrease so that the structure inside will be weak and cause the compressive strength to be low, while the variation of adding coconut shell charcoal powder 2.5% has an increase of 2.07% against normal concrete compressive strength. From the results of the characteristic concrete compressive strength obtained with substitution variations of 2.5%, 5%, and 7.5% respectively of 278.74 kg/cm2, 243.43 kg/cm2 and 238.96 kg/cm2, the concrete These include class II K 275 concrete (middle class concrete) structural concrete.
