Abstract

The south Pacitan district's coastal area in Indonesia has become a tourist place because of the more beach with captivating coral. However, that area's natural resources have not altered the function of construction material. Many research uses the coral reef to admixture concrete material in other countries that affect compressive strength. In this research, the coral reef from Pacitan modified the original dimension of fine aggregate for material substitute o to become the coral sand of fine aggregate with the different material characteristics from other coastal areas. The sample variation was created into four categories, and five samples in every category were concrete without coral sand or 0% coral sand content, 75% with coral sand, 85% with coral sand, and 90% with coral sand. All samples were tested when the concrete age was achieved 28 days after immersing for 14 days, so the concrete was in the maximum setting time condition. The result shows that the percentage effectiveness of coral sand content is 75% as fine aggregate substitution by increasing the compressive is 15.24%, however higher coral sand content causes the decrease until 27.12% to concrete without coral sand, this result can effect by the material characteristic of coral sand when changing the dimension

Abstract

Abstract. Public buildings are buildings used by people from various walks of life, which are built or intended not for the benefit of private residences, but for the general public which are identical to community service centers (Siti Azizah, 2013). One of the public buildings is the Johar market, Semarang. An important aspect of a public building is fire safety. The purpose of this study was to determine the level of reliability of the public building security system against fire hazards in the Johar Semarang market (Johar Selatan), and the readiness of the occupants of the Johar Semarang market building in the face of fire disasters. The method used in this research is descriptive-quantitative research method which is collecting data obtained from interviews, field notes, personal documentation, researcher notes, and other supporting documents. The results of the analysis of the utility component assessment of the four variables resulted in a Building Safety System Reliability Value (NKSKB) of 86.12%, based on these results it can be concluded that the reliability value of the building is in good and safe condition. The level of readiness of residents in facing the danger of fire disasters is still in the poor category with an average level of readiness of residents of 51.12%. This shows the need for increased application of protection systems and rescue facilities, especially for several protection systems that are still damaged and not functioning as well as socialization to residents regarding the use of fire extinguishers, fire simulations, and the need to provide adequate PPE.Keywords: Public Buildings, Level of Reliability, Occupancy Readiness

Abstract

In construction projects that occur in Indonesia, implementation often experiences delays and cost losses where the realization in the field does not match the planned schedule and planned budget due to several factors that occur, even though a thorough cost plan has been prepared, in practice in the field there are still many problems that arise problems in implementation. So the Earned Value Concept or EVM (Earned Value Method) method is used to overcome this problem to determine the implementation cost performance during the project and the indicators used for analysis include: BCWP (Budget Cost of Work Performance), BCWS (Budget Cost of Work Schedule), ACWP (Actual Cost of Work Performance), SV (Schedule Variance), CV (Cost Variance), SPI (Schedule Performance Index), CPI (Cost Performance Index), ETS (Estimated Temporary Schedule), and EAS (Estimated All Schedule). This research aims to evaluate the cost performance of the Wirosari - Karangasem Subdistrict road section improvement project. Wirosari uses the Earned Value Concept method. This method is used to measure project performance by comparing the value of the results achieved (Earned Value) with the planned value (Planned Value) and target value (Budgeted Cost of Work Performed) from week 1 to week 16 using the Concept Earned Value or EVM (Earned Value Method). From the results of this research, the performance of project implementation costs or calculations is knownCost Performance Index (CPI) Whichcut offweek 16 of 34 weeks in the period 6 to 12 May 2024 was 1.156 and there was no CPI value 1 with Cost Variation (CV) week 16 amounting to IDR 589,440,708.64, so that if the project implementation performance in the weekly reporting remains the same until the project is completed, the estimated costs required to complete the remaining project work orEstimate To Complete (ETC) amounting to IDR 1,294,766,228.89 so that the total estimated project costs required to complete the project work orEstimate At Completion (EAC) is IDR 5,075,881,759.65 and the estimated profit obtained from the project or Variance At Completion (VAC) is IDR 791,424,240.35

Abstract

The development of construction methods used in construction has progressed from year to year and in planning the construction of a building it is necessary to select several construction methods. Among them are casting methods that can be done conventionally in a more modern and practical way, namely by using precast. In this research, the floor slab construction method is planned using the conventional floor slab method and the precast half slab method in the Kajen Regional Hospital construction project. The purpose of this research is to analyze the cost efficiency and construction time between the conventional floor slab method and the precast half slab method. The results of the comparison analysis of the conventional floor slab method require a cost of Rp797,269,777.81 with an implementation time of 64 days while the precast half slab method requires a cost of Rp1,470,907,469.89 with an implementation time of 72 days.

Abstract

The condition of the land in Banjarmasin is swamp land (commonly called soft soil) with low bearing capacity so that a special and suitable foundation is needed. This makes the uniqueness and characteristics of the foundations that are often applied in this area. The type of foundation that is often used is to follow materials such as wooden poles or concrete pillars. This is an advanced application of the shallow foundation type. In this study, an in-depth study of the types of foundations on swampy soils in Banjarmasin will be carried out in the form of types including shallow foundations. It will be investigated by comparing the field findings in the area around and outside the city of Banjarmasin. Comparison of the types of foundations found will identify how they are applied. Field observation studies were carried out at various construction sites in Banjarmasin and the surrounding area, especially objects of low-rise buildings and other uses such as fences and earthfill retaining walls. The data is presented in a descriptive manner. The purpose of this study is to provide an applicative description of the foundation in the Banjarmasin swamp land with a comparison of the types of foundations in the surrounding area. It will identify the foundation materials that can be applied and how the application techniques are implemented in the field.
