Abstract

The development of machine learning in predicting the mechanical properties of alloy steel has become an important research subject in recent years. This is due to the ability of machine learning to extract complex patterns from large and intricate data, which can be used to understand the relationship between chemical composition, microstructure, and mechanical properties of alloy steel. This research aims to design a machine learning model to predict the mechanical properties of low alloy steel, such as Yield Strength (YS) and Ultimate Tensile Strength (UTS), based on the percentage composition of chemical elements in low alloy steel and the heat treatment applied. The machine learning model in this study consists of 10 input variables and 2 target variables. The research compares the performance of 3 machine learning algorithms, namely Decision Tree (DT), Random Forest (RF), and Artificial Neural Network (ANN). The research findings indicate that the ANN algorithm model performs best in predicting the mechanical properties of low alloy steel. This model has Mean Absolute Error (MAE) values of 16.5 and 19.593 for predicting YS and UTS, Root Mean Square Error (RMSE) values of 19.111 and 22.005, and coefficient of determination (R) values of 0.964 and 0.947 for YS and UTS respectively. The modeling uses the ANN algorithm with an 80% training data and 20% testing data split, and applies the K-Fold Cross Validation method with a value of K=5. The best parameters obtained are a learning rate of 0.001, momentum of 0.1, and a hidden layer neuron count of 9. These results indicate that ANN has great potential in addressing the complexity and variability in material data. The implications of these findings are that the implementation of ANN in manufacturing and material engineering industries can enhance the accuracy and efficiency in material strength prediction processes, which, in turn, can aid in designing and developing better and more durable products.

Abstract

Air conditioning is not only important for the comfort of occupants in a building but also for various industrial processes. In the air conditioning process, a device called an Air Conditioner (AC) is required. The AC load can originate from inside the room and from outside the room. This study aims to determine the influence of increased cooling load from outside the room on the distribution of temperature and air humidity inside the conditioned room. The method used in this study involved conditioning four rooms. Two rooms of almost the same size were equipped with two AC units each, while the other two rooms used one AC unit each. Temperature and air humidity data inside the rooms were recorded every 20 minutes, as well as the outside air temperature. Dry bulb thermometer (Tdb) and wet bulb thermometer (Twb) were used to record temperature and humidity data, along with an environmeter. The research data were processed using available equations and with the assistance of a psychrometric chart. The research findings revealed that the average distribution of temperature and air humidity in the meeting room and office headroom of the Pertamina DP-LPG Office in Binjai was 20°C-23°C and 59%-65%. For the distribution office and sales service room of the Pertamina Fuel Filling Terminal in Kisaran, the distribution of temperature and air humidity was 25°C-29°C and 62%-66%. From the test results, it can be concluded that the distribution of temperature and air humidity is highly influenced by the capacity of the AC units and the cooling load entering the room.

Abstract

PT. XYZ is one of the palm oil processing companies located in the Riau area. The purpose of this study was to determine the right type of machine maintenance, especially for the worm screw press, because this part often experiences wear and tear which affects the results of pressing palm oil into oil. Wear and tear can partially reduce the surface of the machine and affect the performance of each machine. The service life of the worm screw press provided by the manufacturer is 1000 hours. However, usage at the Sebanga Multi Sawit factory reaches 1300-1500 hours. This proves that there is a need for further studies on good maintenance methods on screw press machines. The calculation of the wear rate and the depth of wear is used to determine the amount of wear that occurs. Solutions that can be done are welding, pack carburizing, and flame hardening on the worm screw press.

Abstract

The demand for metal materials in the industry is currently on the rise. However, existing metal materials often fail to meet the desired properties and characteristics. One such material is carbon steel, which is extensively utilized across various industrial sectors, particularly in small and medium-scale industries as a construction material. This study aims to investigate the impact of holding time and quenching variations on the pack carburizing process, as well as to determine the hardness value of carbon steel before and after undergoing pack carburizing. Experimental research was conducted using Rockwell hardness testing on 16 specimens, with 5 points tested on each specimen. The specimens were subjected to pack carburizing using mangrove wood charcoal at a temperature of 900°C, with holding time variations of 30 minutes, 60 minutes, 90 minutes, and 120 minutes. Different cooling media were utilized, including seawater, rainwater, well water, and mineral water. The results revealed that specimens treated with a holding time of 120 minutes and quenched with seawater exhibited the highest hardness of 83.94 HRA. Prior to the pack carburizing process, the hardness was 47.54 HRA, which increased to a range of 60.72 HRA to 83.94 HRA after the process.

Abstract

Candlenut seeds are one of the plants that grow in Indonesia. Candlenut leaves and seeds have many benefits that are useful for human life. Candlenut oil can be used as a raw material for making varnish, paint, soap, fabric oil, resin, synthetic leather, lubricants, compost, and cleaning or polishing mixtures. Candlenut fruit has a shape ranging from oval to round, green to brownish green, with a length of ± 5–6 cm and a width of ± 5-7 cm. One candlenut contains one to three candlenut seeds. To get the candlenut seeds, they must be removed from their hard and thick shell by breaking them.So far, getting candlenut seeds has been done by breaking them manually by hitting them one by one. This is certainly not effective and takes a long time. Based on this, a tool was designed and made for breaking candlenut shells using a 2 HP motor drive. This candlenut shell breaker tool consists of a throwing part that rotates vertically, which, due to the centripental effect, throws the candlenut kernels against the wall of the breaker. The broken candlenut kernels and shells fall down into the filter section to separate the kernels and shells, then the candlenut kernels go inside. holding containers. To get the ideal launcher rotation, several speed variations were tested, namely: 1. 250 rpm, 2. 350 rpm, and 3. 500 rpm. Of the three variations of rotation, the best rotation was obtained with the shell breaking and the seeds releasing well without breaking, namely at 350 rpm.

Abstract

Energy efficiency is a crucial aspect of energy saving efforts. Energy efficiency is an important factor in reducing energy consumption and environmental impacts. One of the important steps that can be taken in achieving energy efficiency is to conduct an energy audit. An energy audit is a systematic process to evaluate energy use in a building and identify energy saving opportunities that can be done. RETSCreen Expert is one of the software that can be used for energy audits. This research focuses on analyzing the comparison between manual calculations and calculations using RETScreen Expert software on building energy efficiency. The factors used to analyze energy efficiency are air conditioning systems, room lighting systems, and the use of other electronic devices, over a one-year period. The analysis results show that there are differences in calculations between the use of manual methods and RETScreen Expert. The difference between manual calculation and RETScreen Expert is 15.42%. With this difference, it is assumed that manual calculations and calculations using RETScreen Expert do not have too much difference. The results of the energy audit also show that the air conditioning system (HVAC) is a major contributor to the building's energy consumption.

Abstract

The particle size can effect the mechanical properties of composite materials. Variations in particle size will form different mechanical properties in the composite. The particle size variations used in this research are 100 mesh, 120 mesh, and 140 mesh. Making composites using a volume fraction of 30% aegle marmelos shell powder, 20% aluminum powder, and 50% epoxy resin using the hand lay-up method. This research design uses true experimental design with posttest-only design type, there is an experimental group (composite) and control group (Indoparts brand brake pads). Mechanical testing carried out is toughness / impact testing, rockwell-b hardness testing and wear testing. The highest toughness value was obtained in the composite with 140 mesh particle size variation of 0.01180 J/mm2. The highest rockwell-b hardness value was obtained in the 140 mesh particle size variation of 76.9 HRB. The hardness value is closest to the value of the Indoparts brand brake pad. This shows that the smaller the particle size, the hardness value increases. The most optimal wear test results were obtained in the 100 mesh particle size variation with a value of 5.7357 × 10-7 mm2/kg. This value is the closest value to the value of the Indoparts brand brake pad. So it can be concluded that aegle marmelos shell powder can be recommended as an alternative material for motorcycle brake pad.
