Abstract

The increasing demand for sustainable energy solutions has driven the adoption of solar photovoltaic (PV) systems in various industries, including aquaculture. This study designs and simulates a solar power system for small-scale catfish (Lele) pond operations using the System Advisor Model (SAM). The methodology includes assessing energy requirements, selecting system components, conducting simulations, and performing an economic feasibility analysis. The results indicate that the designed 12-panel, 3-battery solar system effectively meets the pond’s daily energy demand while ensuring continuous operation during low sunlight conditions. The SAM simulation confirms stable electricity generation throughout the year, with seasonal variations minimally affecting efficiency. The economic analysis reveals that PLTS costs Rp. 150,365 per month, compared to Rp. 151,620 for PLN electricity, showing small but valuable long-term savings. Despite the high initial investment, solar power offers price stability, energy independence, and reduced reliance on fossil fuels. This study demonstrates that solar energy is a viable, cost-effective, and sustainable alternative for aquaculture operations. Future research should focus on optimizing system efficiency and integrating hybrid energy solutions to further enhance performance and financial benefits.

Abstract

The rapid development of information technology has driven the need for a database system that is able to manage data efficiently, especially in e-commerce information applications that have large and dynamic data volumes. This study aims to analyze and compare the performance of relational database systems (RDBMS) with NoSQL databases in the context of e-commerce applications. The research is carried out with a qualitative approach through the literature study method or library research that examines various academic sources, including journals, books, and previous research reports. The analysis was carried out on several key performance aspects, such as scalability, speed of data access, flexibility of data structure, and ability to handle big data. The results show that relational databases still excel in the consistency of complex data and transactions, but have limitations in terms of horizontal scalability. On the other hand, NoSQL databases, such as MongoDB and Cassandra, show better performance in handling unstructured, large-scale data, and fast access needs, although at the expense of some aspects of consistency. These findings indicate that the selection of database types needs to be adjusted to the needs of the system and the characteristics of the data managed. This study makes a theoretical contribution to understanding the comparative performance of the two systems and becomes a reference for e-commerce system developers in determining the optimal database architecture.

Abstract

Cast iron smelting is carried out with the main materials, namely steel scrap (C) 0.08% and recycled material FC 25 (C) 3.37% so that the mixture of the two raw materials results in the carbon content being less than the FC 25 target which has a content range (C) between 3.10% – 3.40% (JIS G 5501). In order for element (C) to meet the material standardization criteria, a carburizer is used as an addition to element (C) in the smelting process. This research uses an induction furnace with a capacity of 1500 kg for the melting process. Metallographic testing aims to see the comparison of the microstructure that occurs. Brinell hardness testing is carried out by providing 5 point indent traces on the surface. (α) and 2 points in the phase (α+Fe3C). The research results show that the addition of element (C) using a carburizer with a fixed carbon content of 91.57% and 96.7% in casting FC 25 material affects the value of material hardness, phase hardness and microstructure in FC 25 material. The use of carburizers with different contents This does not affect the graphite shape, graphite type and graphite size. The use of a 96.7% carburizer produces a Brinell hardness value of 205 HB, Vickers 259 HV and a pearlite phase percentage of 59% which is higher than a 91.67% carburizer which produces a Brinell hardness value of 184 HB, Vickers 238 HV and a pearlite phase percentage of 56%.

Abstract

Pressure vessel is a container used to store fluids and is very necessary for various industrial activities. Fluids stored in pressure vessels are fluids that have special characteristics and treatment, such as fluids at low or high temperatures, pressurized fluids and so on. In general, a pressure vessel is a container made of metal. Materials that contain metal will definitely experience corrosion. Corrosion can occur, one of the reasons is because there is a chemical reaction on the metal surface caused by the low pH of the water and humid air, so that the metal becomes thinner over time. This will affect the strength of the metal to withstand pressure. The thinner the metal, the less pressure it can withstand. With corrosion, the pressure vessel's ability to withstand pressure will decrease. If the pressure held is higher than the capacity of the pressure vessel, it can cause work accidents. This research will analyze the service life of pressure vessels using inspection procedures based on Minister of Manpower Regulation Number 37 of 2016 concerning Occupational Safety and Health of Pressure Vessels and Storage Tanks. To calculate the effect of thickness on the pressure of the pressure vessel, it will be based on the formula obtained from ASME sec VIII, div.1 regarding boilers and pressure vessels. The pressure vessel that will be tested is of the Jiangsu Ashun brand at PT. Setia Gas Jaya. From the results of analysis and testing, it shows that the pressure vessels at PT. Setia Gas Jaya has the point that experiences the most corrosion, namely at the bottom-head, which was originally 6.8 mm to 6.62 mm after 2 years and 3 months of operation. The results of the analysis also show that with a working pressure of 3.3 MPa, the pressure vessel can be operational for 13 years 3 months 13 days, or its remaining useful life is 11 years 13 days starting from June 2023.
