Abstract

This research aims to analyze the influence of the use of the Kreta Api Indonesia Application on the lives of students in Palembang using a simple linear regression method. Data collection was carried out through questionnaires distributed to students who used the application. The independent variable in this research is the usability of the application (Trust/X) and the dependent variable is student participation in using the application (Participation/Y). The results of simple linear regression analysis show that the significance value is 0.006, which is smaller than 0.05. This indicates that the Trust variable (X) has a significant effect on the Participation variable (Y). Apart from that, the calculated t value of 2.861 is greater than the t table of 2.01063, which also confirms that the Trust variable (X) has a significant influence on the Participation variable (Y). From these two test results, it can be concluded that the usability of the Kreta Api Indonesia application has a significant influence on student participation in Palembang in using the application. This shows that the higher the level of student trust in the application, the higher their participation in utilizing the application for their transportation needs.

Abstract

Ship launching is a crucial stage in shipbuilding, and the airbag launching method has become widely adopted due to its flexibility, cost efficiency, and better safety compared to conventional methods. The ship launching stage is a crucial part of the ship's transition from land to sea, representing a significant innovation in the maritime field. Among the various methods available, the use of airbags has become one of the most effective and widely applied techniques. The approach taken is a quantitative approach to ensure accurate calculations in the process of launching ships using airbags. The quantitative approach aims at calculating the right number and distance between airbags to ensure the safety and efficiency of ship launching, in accordance with the industry standard C/B T 3837-1998. CB/T 3837-1998 standard can be applied to ensure stability and safety during the launching process, as well as minimize the risk of damage to the ship and ensure the launching process runs smoothly. This research aims to calculate the number and distance between airbags used in the launching of a 330-foot barge. The main ship dimensions and airbag specifications were obtained through field interviews to support accurate calculations. The results show that 18 airbags are required, with a distance between airbags ranging from 6.66 to 11.78 meters using a crossover arrangement configuration. This calculation is based on the main dimensions of the ship and the specifications of the airbags used. T

Abstract

PT Tunas Sumber Idea Kreasi Kimia is a company engaged in chemical production, such as alkyd resin, amino resin, acrylic resin and latex emulsion. The purpose of this study is to overcome the excess inventory of steel drum type packaging which causes losses because there are inventory costs consisting of purchase costs, ordering costs and storage costs. The method used in this research is the Just in Time (JIT) method. The results showed that the Just in Time (JIT) method obtained an inventory cost of Rp. 5,244,056,000 which is 10% more efficient than the calculation results according to company policy which obtained an inventory cost of Rp. 5,816,152,000 or a savings of Rp. 572,096,000. So that the Just in Time method can be applied at PT Tunas Sumber Idea Kreasi Kimia to save on inventory costs and improve the company's operational efficiency.

Abstract

The total use of electrical energy in a building or structure, one of them is the use of an air conditioning (AC) system. There are still many uses of air conditioning (AC) systems based on halocarbon refrigerants (R-22) in a building or structure. Refrigerant 22 is a type of halocarbon refrigerant that is widely used in Split ACs. The author conducted research on an LG 2 PK AC by replacing the refrigerant which was still based on Refrigerant 22 with the hydrocarbon refrigerant Musicool 22, then the data results were analyzed to determine the performance of the AC. From the results of the refrigerant retrofitting carried out on March 1, 2022, it was 1,715 Watts. After replacing the refrigerant type from refrigerant 22 to Musicool 22 refrigerant, the electric current dropped to 1,305 Watts in April 2022, 1,352 Watts in May 2022 and 1,346 Watts in June. so that the electrical power efficiency was obtained by 369 Watts and the percentage of electrical power savings was 21.51% compared to March 2022. An alternative to replace halocarbon-based refrigerants in the Split air conditioning (AC) system is hydrocarbon refrigerants, this is a solution in terms of using more environmentally friendly refrigerants and a small global warming effect.

Abstract

In Indonesia, one of the government's programmes is village electricity. For remote villages in mountainous areas, the construction of micro-hydro power plants is one of the answers to the government programme. Power generation in this way is very suitable for our country, given the natural conditions consisting of many mountains that have streams of river water. In turbines we recognise various types of turbines used, we can use francis, kaplan and pelton turbines. The use of these turbines depends on the potential head owned, Pelton turbines that use the principle of impulse require a relatively high head. In this study, it will be studied how the effect of nozzle angle variation and the number of blades on the performance of pelton turbines. The test results show that the tilt angle 65° produces higher rotation at 900-910 rpm while the tilt 90° produces lower rotation around 800-880 rpm. While the effect of the number of blades used is not so significant in the performance of pelton turbines, it can be seen in the use of the number of blades 9 and 18 at the tilt 65° nominal rotation that occurs around 900-910 rpm.

Abstract

The development of the ironing table product that is currently made only uses the same design, there is no difference in terms of shape or form and there are not many additional functions. This study aims to identify the size of the ironing table with anthropometry, create a design for developing an ironing table and product development after being folded into a chair, and measure the comfort of product development with a product reference using Rapid Upper Limb Assessment (RULA). In this study, anthropometry was used to determine the size of the product to be made, and Rapid Upper Limb Assessment (RULA) was used to identify and compare the comfort between reference products and products being developed. The results of the introduction of the ironing table product size using anthropometry are the height of the ironing table of 105 cm, the height and width of the ironing table of 50 cm, the length of the ironing table of 120 cm, the height of the chair seat of 40 cm, the width of the chair seat of 60 cm, the length of the chair seat of 50 cm, and the height of the chair backrest as high as 125 cm. Based on the results of the comfort analysis using RULA, it can be seen that the development product has a smaller value compared to the reference product, so the conclusion is that overall the development product is more comfortable to use than the reference product.
