Abstract

This research is a development of previous research with the ecoprint boiling tool (APEc_1), this tool has been used by the company for the ecoprint production process. The development of demand for products such as shoes, bags and wallets made from ecoprint leather has increased quite well. It turns out that this condition is sometimes not followed by the availability of leather raw materials that have been diecoprinted. APEc_1 is only able to produce 2 pieces at a time by boiling with a duration of 2 hours, so if this tool is used continuously, in one working day it is only able to produce 8 sheets of eciprint skin. Another complaint is that this tool cannot be used for the process of boiling fabric raw materials. Boiling cloth requires a higher temperature with a duration of 2.5 hours. This study uses an experimental method with a creative rational approach. This method is quite simple but gives optimal results for simple cases and not many product forming variables. The dimensions of the ecoprin 2 boiling device (APEc_2) are designed using the dimensions of a two-burner stove for length and width measurements. As for the height of the tool using general anthropometric dimensions, the tool dimensions are still the same as APEc_1. With the creative rational method the researcher paid attention to the dimensions of the "lontong" circle in APEc_1, and obtained data that there was still a large enough space to be utilized by increasing the number of rolls from 2 to 5. The addition of a roll changes the shape of the lid which was initially tilted to a straight one so that you can add a "lontong" roll. The result of this research is the APEc_2 boiling device with a total of 5 rolls, and can be rotated simultaneously using a crank on one of the rolls connected to the connecting chain of the other rolls. The roll is made of steenless pipes, so APEc_2 can be used for the boiling process of raw leather and fabric raw materials, and boiling can be done together, with this function, APEc_2 is a multi-functional ecoprint boiling tool.

Abstract

Functional power transmission system to reduce voltage from 150 kV to 20 kV as part of the main substation. During operation, the substation requires a DC power source as a control tool to support the performance of the substation. The source of direct current (DC) to the substation is taken from the rectifier and batteries installed in the installation parallel to the load or what is usually called a DC system. The battery is a backup DC source used to provide DC power to protection devices, PMT and PMS drive motors, as well as telecommunications equipment. To maintain battery reliability it is important to provide DC power in the event of a failure. Regular maintenance so that the battery can operate at peak performance. Battery maintenance is carried out by measuring voltage and weight, checking battery type, temperature and electrolyte capacity. This research was conducted to determine the reliability and suitability of 110V batteries at the Sepatan substation after maintenance. Results from testing the voltage per 110 Vdc battery cell at the Sepatan Main Substation with the SAFT NIFE brand, type SBLE 300-2, capacity 300 Ah, and a total of 88 cells. In the results of testing the voltage per 110 Vdc battery cell, the average battery voltage condition before BCT was 1.32 V, charging was carried out using the battery boosting method between 1.30 and 1.45 V, with this the average temperature of the battery 110 Vdc is 29oC and the specific gravity of the electrolyte in measuring this 110 Vdc battery is 1.221gr/cm3. In the 110 Vdc battery cell voltage test carried out for 5 hours with complete data, the total voltage measured was 112.7 V. In general, based on the capacity test results It could be said that the condition of the 110V batteries at the Sepatan 150 kV substation is always good and reliable or ready to be used when there is a problem.

Abstract

The development of science and technology is very influential in all fields, including the health and medical fields. To increase the value of medical personnel services, monitoring patient conditions in real-time is necessary. Medical personnel need information on the patient's condition to take preventive and effective action. The information required by medical personnel is vital signs of the patient's condition in the form of heart rate and body temperature. The patient's heart rate condition can be read with a pulse sensor, while body temperature can be read with the DS18B20 temperature sensor. The results of the heart rate and body temperature sensor readings are displayed on the Liquid Crystal Display(LCD) screen with the help of the Inter-Integrated Circuits (I2C) module when communicating with the Arduino Uno. So that medical personnel can monitor the condition of the patient's heart rate and body temperature remotely without using cables, an intelligent cellphone with the Thingspeak platform application is used. Smartphones with the Thingspeak application can communicate with heart rate and body temperature sensors with the help of the ESP8266-01 module. From the research that has been carried out, it was found that the average error in temperature readings was 1.4% and heart rate was 3.6%. This patient condition monitoring tool can be implemented in hospitals to monitor the patient's condition through heart rate and body temperature. From the research that has been carried out, it was found that the average error in temperature readings was 1.4% and heart rate was 3.6%. This patient condition monitoring tool can be implemented in hospitals to monitor the patient's condition through heart rate and body temperature.

Abstract

This research is about studying a hybrid composite that combines synthetic and natural fibres to achieve optimal strength while utilizing natural fibres, which are abundant on the Indonesian coast. The synthetic fibre used in this research is glass fiber in the form of woven roving, while the natural fibre uses coconut fibre in the form of a mat. The use of glass fibre, which is known to be strong and has good flexibility, aims to improve the mechanical properties of coconut fibre. Hybrid composites are made using the hand lay-up method with a Glass Fiber/ Coconut Fiber / Glass Fiber [GF/SK/GF] layer arrangement. Weight fractions are varied to find the optimum weight fraction that produces a hybrid composite with the best tensile strength. Composite specimens were made and subjected to tensile tests following ASTM D-638 standards. The test results show that the average strength of this hybrid composite is 46 MPa with an elastic modulus of 1029 MPa. The optimum weight fraction for this composite is 11% glass fibre, 19% coconut fibre, and 70% resin, producing a tensile strength of 56 MPa.

Abstract

The majority of prosthetic leg products currently circulating in Indonesia are imported and made from stainless steel. Even though it has several advantages, the price and production costs are relatively expensive. So, it is necessary to introduce other materials to make the prosthetic legs more affordable. One alternative material is aluminum. Aluminum material can be fulfilled by recycling used aluminum. This research conducted a study on the tensile strength and yield strength of remelting used aluminum pistons based on the hardness value. The research material is aluminum from used pistons from large vehicles (buses or trucks) mixed with 20% silicon aluminum. Specimens with a target silicon (Si) content of 12%, 14%, and 16% were cast using a sand mold using the closed mold casting method. The Brinell hardness test refers to ASTM E10-15. The reference for the feasibility of melting as an alternative material is that its yield strength must be greater than the maximum stress on the prosthetic leg, which is 153 N/mm2. The average hardness for the Si 12%, Si 14%, and Si 16% samples is 87.35 HB, 101.01 HB, and 112.03 HB, respectively. The tensile strength for the Si 12%, Si 14%, and Si 16% samples is 125.30 N/mm2, 175.33 N/mm2, and 215.44 N/mm2. The yield strength of the Si 12%, Si 14%, and 16% samples is 80.02 N/mm2, 112.75 N/mm2, and 138.47 N/mm2. The melting results for the three samples cannot yet be applied to prosthetic limb materials because the yield strength is lower than the maximum stress that occurs.

Abstract

In an era of increasingly advanced technology, innovation in the field of sustainability and ease of mobility has become the main focus for improving the quality of life and independence for various groups of society, including people with disabilities. Intelligent wheelchairs are one example of a solution that has emerged to increase mobility and independence for savvy wheelchair users. This research aims to monitor the power of bright chairs to understand power consumption and energy use in developing intelligent wheelchairs. This test uses percent error data. The average results from calculating percent error data are relatively low. So, the current and voltage sensors are suitable for use in this percent error test. Tests were carried out with load and without load. In testing, the voltage and current required are the same. However, the speed produced by wheelchairs is different. When testing with a load, the wheelchair's speed is relatively slow. Meanwhile, when testing without load, the wheelchair can go fast. The power released at Pulse Width Modulation (PWM) 50, 100, and 255, respectively, has an average value of 23.37 W, 36.47 W, and 43.61 W. This data has different graphic results. The higher the PWM value, the greater the power released. Apart from that, the faster the wheelchair rotates, the more wasteful the battery is.

Abstract

Workplace fire incidents can harm many parties, so a fire can cause fatalities, material losses, work losses, and other losses that can have fatal consequences. This research aims to understand the working principles of the fire detection system, determine the role of the fire alarm system in the security and safety of building occupants, and determine the causes of false alarms in the fire alarm system in the Nusantara I DPR RI Building. This research uses qualitative procedures with a descriptive approach. Information retrieval methods take the form of observation, interviews and documentation. The study showed that this fire warning system could detect and give a warning sound to all building occupants. This is due to a fire initiated by sending a signal from the detector and connected to the master panel. The role of a fire warning system in a building is to warn building occupants, workers or visitors about the presence of a fire so that they can immediately take appropriate evacuation action and extinguish the fire if possible. The factor that causes false alarms is that the detector in this fire alarm immediately detects things like cigarette smoke, dust, problems with the installation, and damaged detectors.

Abstract

The role of standard measurements for low-capacity forces and torques is increasingly more significant, along with the development of automation technology, micromachines, biomechanical systems, and so on, which are relatively small in size. The force and torque standard machine needs to be developed to meet these needs. In this research, a study was conducted to evaluate the possibility of making a low capacities hybrid torque-force standard machine, that is a deadweight force standard machine whose function is optimized so that it can also be used as a torque standard. This preliminary development is designed for a 2.5 N – 50 N force capacity and torque of 0.25 N·m – 20 N·m. The development of a design with a hybrid function as a torque standard is built using a detachable arm along with a wire sling and pulley bearing. The results of preliminary analysis and simulation calculations show that developing a standard low-capacity hybrid torque-force engine is possible. That is meeting the machine uncertainty requirement target of 0.1% for force quantities and 0.3% target for torque quantities. The target uncertainty value that can be achieved also depend on the manufacturing process.

Abstract

In aviation, security and safety are the main priorities, so the components' quality must meet specified standards. One of the components that will be discussed is the arm link bracket located on the wing or left wing of the aircraft, which functions as a support fixture for the arm link. This component is made from Aluminum 7050 T7451 material. In this case, a decrease in the hardness value of Aluminum 7050 T7451 was found to be 80 HB from the standard 82–92 HB, which is feared to be a problem in the future. So, it is necessary to find out the cause so that similar incidents can be avoided. The method used to analyze the leading causes of the decrease in the hardness value of Aluminum 7050 T7451 is by studying literature related to things that allow a reduction in material hardness and using the help of CAD/CAE software for Finite Element Analysis (FEA). The results obtained from the cause of the decrease in hardness of the Aluminum 7050 T7451 material are heat exposure, which is the only heat source based on sheet processing, and heat exposure occurs more than once. In addition, the thermal simulation results show that the heat exposure area spreads evenly across all parts in one exposure. The specific cause cannot yet be known, considering that the heat source of the machining process has many factors, such as the condition of the coolant, the condition of the cutter tools, and the unknown feed speed. In this case, the simulation results show that the maximum stress of 259.6 MPa is still in the safe category with a safety factor value of 1.491.
