Abstract

The degradation of concrete strength may occur due to extreme environmental factors such as sea or coastal areas. Those factors can decrease the durability level of concrete structure signified by the corrosion of reinforced concrete structure. The use of fly ash as a concrete mixture is expected to minimize corrosion in concrete structures. Since fly ash has small particles, it can fill small voids in concrete and minimize corrosive substances. The investigation parameters in this study employed two types of corrosion acceleration test modelling using a 15x15x15cm cube tested object with a concrete quality of 40 MPa. Meanwhile, fly ash involves classes F and C within the level of 20% as well as applied corrosion prediction by 10% and 20%. The addition of fly ash to the concrete mixture can reduce the mass loss of reinforced concrete. The maximum mass loss on a normal test object with a corrosion prediction of 20% was obtained at 18.22%, while a 20% corrosion prediction obtained the smallest value for the SCMFA-C test object at 17.04%. The 20% corrosion prediction obtained the largest distribution of 0.355 mm on the normal test object and the smallest distribution of 0.299 mm occurred on the SCMFA-F test object. Thus, the addition of fly ash to the concrete mixture can reduce the distribution of corrosion and mass loss in reinforced concrete.

Abstract

This study aims to identify the priority weight in decision-making in the Sanur Port construction project, which involves various stakeholders with diverse interests and powers. Decisions taken in this project can determine the success of implementation and reduce the impacts caused, especially in dealing with problem situations. The study was conducted using a focus group discussion method involving experts who are experienced in port development. Furthermore, the Rank Order Centroid (ROC) method was used to calculate the priority weight of each stakeholder in decision-making according to expert opinion. The results of the study showed that 11 stakeholders were collected into 4 quadrants in the stakeholder mapping. The highest priority weight is acquired by the project owner (0.5467), JO - planning consultant contractor (0.2567), and construction management consultant (0.1566), which are in quadrant 1, followed by the local government (0.0900) in quadrant 2, and the affected community (0.0400) which is a combination of quadrants 3 and 4. This finding indicates that in decision-making in the Sanur Port construction project, a diverse approach is needed to minimize losses from each stakeholder. The results of this study are expected to offer insight for decision-makers to understand the dynamics of stakeholders in port construction projects. This understanding will help improve the effectiveness of project management in the future.

Abstract

Coal is a deposit of plant fossils that has undergone a peat process over a long period of time. A company in Malinau Regency, North Kalimantan Province, requires replanning for the existing drainage system because its holding pond or sump, which is a former pit, will be re-mined. Therefore, this research re-plans the drainage system to overcome this problem. The methods for data processing comprised the Gumbel method, the Monobe equation, the Seyhan equation, and the calculations of open channels and holding pond dimensions, as well as pump capacity. The mine drainage system creates channels or ditches that function to prevent runoff water from entering the mining area. The channel capacity was 0.6 m3 /second, or 2,261 m3 /hour, with a large runoff of 0.146 m3 /second, or 63 m3 /hour. The channel would be made in a trapezoid shape. Meanwhile, the mine dewatering method used a pumping system to release water into the sump. Using 1 pump of MF-420EX, the total flow of water that could be pumped reached 50,537 m3 /hour with working hours of 20 hours. The sump capacity was 28,825 m3 in a trapezoid shape with dimensions of 95 m surface length, 70 m surface width, 85 m base length, 60 m base width, and 5 m depth.

Abstract

Indonesia, as a country rich in natural resources, has a very diverse mining sector, including oil and gas mining. In an effort to increase national oil production and improve the standard of living and welfare of the community, regulations are needed to regulate the management and business of oil. Regulation of the Minister of Energy and Mineral Resources No. 01 of 2008 concerning Guidelines for the Business of Oil Mining in Old Wells. This regulation is considered an implementation of the principles contained in Article 33 of the 1945 Constitution and provides positive support for Regional Governments that have many old wells. The regulation opens up opportunities for increasing Regional Original Income (PAD) and community welfare through the participation of Village Unit Cooperatives (KUD) or Regionally-Owned Enterprises (BUMD) in oil production in old wells in their areas. In addition, in the distribution of oil, this mode of transportation is also an important aspect for Village Unit Cooperatives (KUD) or Regionally-Owned Enterprises (BUMD) in the Bojonegoro Regency area, which, as one of the regencies in East Java Province, is an area that produces oil and gas that is still active to this day. Oil fields in Kedewan District, Bojonegoro Regency, are generally old fields that have been made since the Dutch era, so their production has decreased. Even so, the potential of old oil wells that have been closed can still be managed and utilized through traditional mining methods by involving local communities both in management and in the distribution of oil by land transportation from oil wells to storage areas in the work area of PT Pertamina EP Asset 4 Cepu Field. This study aims to obtain information about problems in the distribution of oil transportation from old wells to storage/reservoirs related to policies, regulations, infrastructure conditions, and their dynamics. The research methods that will be used involve observation, documentation, inventory, and interviews, with qualitative methods and thematic analysis. The results of this study are expected to produce outputs in the form of scientific articles or national journals.

Abstract

The food industry continuously evolves to meet the increasing demand for high-quality products such as shortening oil. This study analyzes the performance of refrigeration systems in shortening oil production, focusing on the effects of suction pressure on energy efficiency and product quality. Experimental results demonstrate that increasing the suction pressure from 1,2 bar to 1,6 bar leads to a reduction in cooling capacity (Qe) from 110,08 kJ/kg to 91,36 kJ/kg, heat rejection capacity (Qc) from 137,34 kJ/kg to 122,85 kJ/kg, and the Coefficient of Performance (COP) from 4,04 to 2,90. Despite these declines in system efficiency, the penetration value (Pen.V) of the final product increased from 272 mm/s to 314,4 mm/s, indicating an improvement in the texture of the shortening oil. These findings underscore the critical role of optimizing suction pressure and operational parameters to balance energy efficiency and product quality. The study highlights the importance of maintaining precise control over refrigeration system variables to enhance production sustainability and meet industry standards.
