Abstract

A force inside a pipe drains fluid from wells producing oil and natural gas. When the power works exceed the pipe's maximum resistance limit, it will cause deformation in the line. This research aimed to evaluate the height of the trench to determine the threshold of tremendous friction force working on the pipe to withstand the axial force, which can cause upheaval buckling. The method used is the calculation of stress analysis. The line of 12 inches measured its style and voltage was planted in the trench with l.5 meters high and 3 meters wide and the soil density of 14.70kN/m3. The data used in the calculation were the design pressure, the outside diameter of the pipe, the minimum melting point of the line, the design factor, the factor of pipe connections, the derating factor, the modulus young, the thermal expansion coefficient, the pipe installation temperature, the maximum operating temperature, the Poisson ratio, the internal pipe pressure, the sectional area of the inner pipe, the pipe cross-sectional area, the depth of pipe planting, the trench width, the value of pipe nondimension, and the soil density of flowline area. The analysis result indicated that the friction force is 356,025.71N/m, and the axial force is 44,927.35N/m. These results showed that the friction force working on the pipe could withstand the axial force working. The cost of making the trench can still be decreased by reducing the height of the track to l m. The excellent friction force in the channel with a size of lm is 252,501.92N/m, where the value is still more significant than the axial force. In conclusion, the friction force working with the trench lm high can still hold the axial force working on the pipe.

Abstract

Mining activities must always be supported by mechanical equipment that can work optimally to create satisfactory results with minimal cost and effort. Periodic control must also always be carried out because it relates to the company's production target. This research aims to determine the production of the HD985 dump truck conveyance and obtain the amount of lift needed for screening station product (SSP) transportation activities. This research was conducted using data collection methods in the field, discussions with several employees, and existing literature. Then processing is carried out by calculating data from the area using a specific formula and then analyzing the results of the calculations that have been obtained. Based on estimates, it was found that the production of the HD985 dump truck conveyance reached 69.46 tons/hour. And for the number of rides needed with a target tonnage of 1,000 tons, namely 2 units, for a target of 2,000 tons, 4 units are required; for a target of 3,000 tons, 6 units are needed, for a target of 4,000 tons, 8 units are required, for a target of 5,000 tons, 10 teams are needed.

Abstract

Choosing the correct and strategic location can make a big profit for the factory. Conversely, the factory can retain if the factory's site selection is strategic. The purpose of this study is To determine the factors in determining the location of the construction of PLTU PT. Bosowa Energy and know the climate parameter of PLTU PT. Bosowa Energy. The stages and methods of research conducted consisted of four steps: the process of research stages, methods of data retrieval, data processing and locations of data analysis, and the set of report generation. The data taken are primary and secondary; after the data is collected, data are analyzed to determine the factors determining PLTU PT location. Bosowa Energy. PLTU PT. Bosowa Energy in Bangkala Subdistrict Kabupate Jeneponto South Sulawesi Province This location has a climate among other air temperature areas ranging between 18,20 - 27,00 ̊C, rainfall area is quite wet, speed and direction of angina average ranged from 2 until 3 knots, Relative air humidity average 64.8 - 83.5%. The conclusions of this journal are the factors in determining the location of the balance of network, industrial areas, and water areas and climate parameters of rainfall, temperature, humidity, and wind speed.
