Abstract

Fuel storage in storage tanks (SPBT) generally uses manual methods, causing inaccuracies and inefficiencies. To overcome this problem, this research focuses on developing a microcontroller-based automatic measuring instrument with a PING ultrasonic sensor. Manual methods are often prone to human error, while these automated tools are designed to improve measurement accuracy and efficiency. By using a PING ultrasonic sensor, this tool can measure liquid levels with a higher degree of accuracy, reducing the potential for error. This automated process enables real-time monitoring, with measurement results directly displayed on the monitor or LCD. The use of this method also allows measurements based on cylindrical tank type, increasing operational flexibility. The research results show that this tool is more efficient than manual methods, minimizing errors and increasing information availability. Evaluation of the entire system shows that the desired fuel oil stock monitoring system can provide adequate performance, as well as ensure stock maintenance is maintained properly. However, there is an average error of about 0.11% in the tank volume measurements, which is caused by slight curvature in the tank structure. In conclusion, the use of this technology in SPBT is expected to increase fuel management efficiency, reduce operational costs, and provide information on fuel availability accurately and quickly. Thus, this research makes a significant contribution to the development of more effective storage tank monitoring and management systems

Abstract

One of the most important aspects of preventing illegal usage of firearms is safe storage. An inventive way to guarantee that only authorized owners can access the firearms is to incorporate fingerprint technology into the design of electric firearm storage systems. The use of fingerprint technology to increase the security of gun storage is desperately needed. However, issues with the finger's health, such as stains, cuts, and dampness, can impair the accuracy of the detection. This study employs a quantitative methodology using five fingerprint detection situations to test the accuracy of the system. The Arduino ESP was used as the foundation for the system implementation throughout the nine months that the research was conducted at the Kodiklatad Poltekad Electronics Laboratory. According to the test results, the system has 100% accuracy in identifying five different fingerprint detecting scenarios. But limitations are implied by the system's incapacity to identify damp, damaged, or dusty fingertips. Consequently, further thought must be given to these circumstances in order to improve system reliability. The design of an electric gun storage unit using Arduino ESP-based fingerprint technology has the potential to increase the security of gun storage, but more work is needed to address some issues that limit detection accuracy

Abstract

TThe manual measurement of materials using pneumatic systems for inspections remains prevalent, posing challenges in meeting the demands and speed of modern production processes. To address this, there is a critical need for an automated inspection tool capable of generating a significant number of inspection inputs. This research objectives to design and implement an automatic thickness inspection system, employing pneumatic technology and inductive proximity sensors. The study adopts an experimental research design, systematically progressing through literature review, algorithm design, PLC programming, and comprehensive testing. The pneumatic system, known for its high response speed and durability, is capable of accurately measuring material thickness and sorting items with precision. The integration of inductive proximity sensors enhances the system's efficiency in detecting both metallic and non-metallic objects. The research findings reveal a system effectiveness of 95.8% in the initial test and 91.7% in the subsequent test. Notably, deviations in the Ø12 sensor are identified in detecting NG minus material. Despite this, the system's overall effectiveness surpasses the 90% threshold, meeting stringent standard criteria. The study concludes with insights into the identified deviations and underscores the system's effectiveness in meeting high-standard criteria. Recommendations for improvement include modifications to the stopper or proximity sensor position, sensor recalibration, continuous monitoring, and material path separation

Abstract

A single hectare of oil palms may yield 10 tons of fronds annually, with young oil palms producing 40–56 fronds and mature oil palms producing 40–48 fronds. One kind of solid debris that comes from making palm oil is called palm oil fronds. A method is required to lessen palm frond waste because substantial volumes of it will still need to degrade. Waste palm fronds are reduced in size and broken down more quickly with the assistance of a chopping machine. But for slicing palm frond trash, the frond machines that are now in use are not the best. The purpose of this study is to ascertain whether adding more blades to a chopping machine's cutting knife can enhance the chopping process. Two designs with 19 and 26 blades were manufactured and tested for the research, and the results were compared with the cutting knife design from the prior study, which had 24 blades. According to the test results, adding additional blades to the cutting knife will improve the machine's effective capacity by 14.22% and decrease the size of waste palm fronds and leaves, allowing the machine to operate more efficiently. In addition, reducing the size of palm fronds with more knives can make them easier to break down

Abstract

Quality improvement is necessary to overcome the occurrence of defective products during the production cycle. The occurrence of defective products is difficult to avoid. Therefore, the Sugar Factory (SG) business unit at PT XYZ began to implement quality control for sugar production. Based on these events, an analysis of quality measurement is carried out through this research. The methods used in this research are control chart, fishbone diagrams, and failure mode and effect analysis (FMEA). The results of the control map measurement using the p-chart and u-chart show that there is no sugar production process that is out of control. Although nothing is out of control, it is also necessary to analyze it using a fishbone diagram to determine the cause of the defects that occur. The results of the measurements with FMEA can be known sub-factors that have the highest RPN, namely negligence of operations, poor sugar cane sorting, changes in production schedules, incomplete repair areas, and poorly organized layouts. From the results of data processing, it can be seen that quality control needs to be carried out by the company. One of them is by making standard operating procedures (SOP) related to the sugar processing process. In addition, the raw materials for making sugar also need to be considered, so that the process will produce sugar with better quality

Abstract

Passenger boats are a means of transportation that is used to transport passengers to a destination. One of them is a boat for passengers to visit the religious tour of Sheikh Mudzakir's grave. The religious tourism location of Sheikh Mudzakir's grave is located about 2 km north of Blekok Island. However, this passenger boat still relies on fuel oil as fuel to drive the passenger boat's combustion engine. Research on electric boats was carried out by several students at Semarang University. This electric boat uses solar panel technology installed on it to harvest solar energy and convert it into electricity which is stored in batteries to move the boat. This electric boat uses a 3 Phase 1 HP 4 Pole electric motor that uses solar charge control and an inverter as a converter from 12 V DC to 380 V AC. Using a 3 Phase Electric Motor requires a large amount of electricity, because it requires electricity that must be converted to voltage. high, will result in high loss, so that the efficiency of battery use is relatively wasteful. The aim of this research is to carry out tests using a 4 kW 72 Volt BLDC Motor as an alternative solution to replace previous research which used a 3 Phase 1 HP Motor on an electric passenger boat. The results show that the motor rotation of a 4 kW 72 Volt BLDC motor tends to be greater than using a 3 Phase 1 HP electric motor and a 9 HP fuel engine, where previous research showed that the speed of an electric boat can only reach a maximum speed of 4.4 Knots at high mode gas level. , while using a 4 kW 72 Volt BLDC motor it can reach a speed of 8 Knots, which is a huge improvement. Very suitable for using a 4 kW 72 Volt BLDC motor on a 1GT electric boat

Abstract

Heavy Equipment Industry is a company operating in the mining heavy equipment industry. The Quality Control Department continues to strive to maintain and improve the quality of every product produced. During 2022 there were complaints from customers, where there were 7 complaints about hangers detaching from the frame. The hanger is a connecting component between the leaf spring and the chassis which functions as a support for the load. This has a very fatal impact because it is related to safety, unit function and unit productivity. The crack defect caused a repair process by re-welding the part of the hanger where the crack was present. The aim of this research is to reduce the defect rate in Hanger defects. The method used is DMAIC. Primary data and supporting data were collected through field observations to describe actual conditions before repairs. Based on the results of the analysis and improvements that have been carried out, it was found that creating work instructions for the process of attaching hangers to units can help manpower understand the process and work sequence in hanger fabrication. The proposal to add reinforcement check points to the hanger setting check sheet is hoped to be able to maintain the hanger without reinforcement entering the next process and increase supervision of the hanger welding quality.

Abstract

In this work, the performance of a buoyant waterwheel to produce hydrokinetic power is investigated through analytical theory and computational fluid dynamics simulation. The impact of the buoyancy wheel is investigated by establishing the performance parameters through the use of a moving mesh approach and a realizable k-ε turbulence model. Transient simulation is required to comprehend the flow of physical processes. Using moving mesh as a transient methodology of the buoyancy waterwheel, numerical flow simulations and theoretical analytical methods are used in this study to assess the effect of buoyant force generated on the performance of the buoyancy wheel. The buoyancy waterwheel that will be put to the test has eight straight blades and a diameter of one meter.  The pinwheel force and torque created in the numerical flow simulation (CFD) are 414.96 N and 207.48 Nm, respectively, whereas in the theoretical calculation they are 449.06 N and 224.53 Nm, according to the research findings. It is possible to compute the buoyancy wheel's power output and efficiency mathematically, yielding values of 1619.35 W and 68.07%. The buoyancy wheel's power output and efficiency, as determined by numerical flow simulation, are 1495.95 W and 62.88%, respectively. Based on theoretical and CFD study results, the buoyancy wheel generates a standard deviation of 7.62%. Thus, for the buoyancy wheel, a temporary method that makes advantage of the moving mesh characteristic is advised. This method can also be applied as a future alternative energy source for the Piko hydro turbine

The great efficiency and low losses of this static electricity machine are two of its advantages. can aid in lowering greenhouse gas emissions and protecting the environment. While transformers can experience several losses, two main types of losses typically arise: 1. Ohmic or copper losses; and 2. Core or iron losses. This study compares the benefits of low-loss transformers (143 kW) to high-loss transformers (258 kW). It focuses solely on the design and environmental aspects of copper losses (also known as load losses) and core losses (sometimes known as no-load losses). This study's methodology combines qualitative and quantitative methods with a case study of a 30/60 MVA transformer with a voltage rating of 150/20 kV and a mineral oil cooling system. The study concludes is that low-loss transformer design is important, this results in an efficiency increase from 99.57% to 99.80%, losses of 55.4% lower, and an approximate 25% increase in total weight. Environmentally speaking, it can reduce greenhouse gas emissions by approximately 31,347.87 tCO2e, making it more cost-effective, competitive, and environmentally friendly than transformers with 258 kW of total losses

Abstract

Improvements in the efficiency and precision of using the Internet of Things (IoT) to monitor infusion fluid volumes have been particularly beneficial to the health sector. It is now feasible to create intelligent solutions that replace labor-intensive and error-prone manual techniques with the aid of affordable devices like the ESP8266 and accurate sensors. Through the use of an internet connection, the server may easily receive data on the volume of infusion fluids collected by the ESP8266-based system and precision sensors. This enables remote access to real-time monitoring using a web platform. The main advantage of this technology is that it allows medical personnel to adequately monitor patients even when they are nearm not them. This reduces patient distraction and gives patients more time to focus on important medical tasks. By using this technology, healthcare personnel can improve the quality of treatment they give by reducing the chance of human error when calculating and changing IV bags. When medical staff has access to dependable and real-time data updates, they can manage IV fluid management more skillfully and respond to changes in patient situations more quickly. All things considered, these advancements represent significant strides forward in the administration of intravenous fluids, offering more accurate, effective, and conveniently accessible solutions that elevate the bar for healthcare overall
