Abstract

This study examines the minimum effective separation distance between buildings necessary to avert structural damage from building pounding in Padang City, an area particularly vulnerable to seismic events. The study examines 45 structures throughout five districts, classified into three categories according to their height-to-width (H/L) ratio: (0.5–1.0), (1.1–1.5), and (1.51–2.0). Three pairs of ground acceleration records—Imperial Valley-06, Tokachi-Oki Aftershock, and Tokachi-Oki Mainshock—were selected and calibrated to align with the target response spectrum of Padang City using linear time-history analysis. The research assesses structural displacement capacity and drift ratio to ascertain the necessary minimum separation distances. The findings reveal that the minimum separation distance for Category A (H/L: 0.5–1.0), Category B (H/L: 1.1–1.5), and Category C (H/L: 1.51–2.0) spans from 40 cm to 48.4 cm, with a suggested practical separation of 50 cm per building. A separation distance of 1 meter is recommended to reduce the risk of structural collisions during earthquakes. These findings serve as a technical reference for urban planners, engineers, and legislators, facilitating safer building designs, enhanced seismic resilience, and diminished structural damage in earthquake-prone regions.

Abstract

Efficient inventory management is essential for facilitating seamless manufacturing at PT ZYX, especially in managing child part stocks from several vendors. Suboptimal inventory management may result in stock deficits or surpluses, affecting production continuity and operational expenses. This study seeks to evaluate kid part inventory according to its strategic significance and establish safety stock levels for category A goods. The ABC classification approach was utilized to categorize inventory according to significance, and safety stock analysis was performed to determine ideal stock levels for essential items. The findings reveal that among 35 child components, 8 things are classified as category A, 4 items as category B, and 23 items as category C. The maximum safety stock value was identified in child component ID 70025 at 2,891 pieces, whilst the minimum was recorded for ID 70002 at 248 pieces. These findings offer a systematic inventory management strategy that enables the organization to enhance stock control, reduce expenses, and increase operational efficiency. The adoption of ABC categorization and safety stock analysis is anticipated to improve inventory management, facilitating a more efficient supply chain and superior resource allocation.

Abstract

This study looks into the thermal risks and ways to deal with them that come with coal self-combustion at the Alam Barajo stockpile, which is run by PT. Kuansing Inti Makmur. Three coal piles: UHS 12F (±2 months), UHS 01A (±1 month), and Medium 11C (±3 months), were monitored to see how the length of time they were stored and how often it rained affected the temperature rise and the subsequent quality loss. The results reveal that the temperature of the pile rises dramatically with extended storage. For example, UHS 12F had a daily rise of 5.04°C, while UHS 01A saw a rise of 1.65°C. Self-combustion in Medium 11C reached a high of 222.1°C, which caused the ash content to rise by 2.62% and the calorific value to drop. Heavy rain made the temperatures drop for a short time, which suggests that evaporative processes caused the cooling. The study shows that present ways of managing stockpiles, especially the FIFO technique, are not being used to their full potential. To reduce the risk of combustion and keep the quality of the coal, engineers advocate making changes like regular temperature monitoring, correct compaction, covering with tarps, and distributing the coal before it catches fire.

Abstract

The wheat processing industry is one of the vital sectors that involves a complex and sustainable manufacturing process. In carrying out the wheat transfer process, transportation tools equipped with sensors play an important role in ensuring that moving raw materials runs safely and efficiently. In this study, the aim is to understand the types of sensors used in product transportation and the characteristics of each sensor. The method used is a case study method. Milles and Huberman model the qualitative approach. This study uses three types of sensors in the product moving process: proximity sensors, limit switches, and belt monitors. By using these three sensors, product transfer becomes more efficient and safer. Utilizing safety sensors on transportation equipment can minimize errors in the product transfer process and is also safe because it can prevent malfunctions. Applying these three sensors makes it easier for employees to carry out the product transfer process.

Abstract

The accurate assessment of Human Error Probability (HEP) is crucial for aviation safety, especially in complex systems such as the Manoeuvring Characteristics Augmentation System (MCAS). This study compares two widely used human reliability analysis methods, HEART (Human Error Assessment and Reduction Technique) and SLIM (Success Likelihood Index Method), to evaluate their effectiveness in identifying and quantifying MCAS-related human errors. The results indicate that HEART is highly sensitive to human and organizational factors, as in Error Mode 5, where the calculated HEP is 0.164. In contrast, SLIM focuses more on system design and interaction reliability, yielding a significantly lower HEP of 0.0049. The comparative analysis highlights the strengths and limitations of each method, suggesting that a hybrid approach could improve the accuracy of human error assessments in aviation, leading to more effective risk mitigation strategies.

Abstract

A slope is a sloping part of the ground surface that connects the higher areas with the lower areas. Slope stability relies heavily on rock mass characteristics, including the Rock Mass Rating (RMR) and Geological Strength Index (GSI) classifications, which are used to evaluate rock quality and slope stability. This research was conducted at the mine CV. Putra Idola which is located in Teluk Kabung Tengah Village, Bungus Teluk Kabung District, Padang City and Nagari Siguntur, XI Koto Tarusan District, Pesisir Selatan Regency, West Sumatra Province. The goal is to determine RMR and GSI values and identify potential slope instability. The methods used include geotechnical mapping with a 15.2-meter long scanline technique to identify burly structures as well as laboratory testing to obtain the physical and mechanical properties of rocks. The data obtained were analyzed to calculate the RMR and GSI values of different types of rocks at the research site. The results showed that the GSI values on the three slopes studied ranged from 53 to 75, while the RMR values ranged from 57 to 75. Based on this classification, the Fresh Andesite and Hornfels rocks are included in the "Good" category, while the Weathered Andesite rocks are included in the "Medium" (Fair) category. The results of this study provide important information for the mining industry in efforts to mitigate landslide risk and design safer slope designs. In addition, this study also emphasizes the importance of rock mass classification analysis in the evaluation of slope stability in open pit mining activities.

As industrial technology continues to advance, the demand for efficient and automated motor control systems is increasing. Three-phase induction motors are widely used due to their durability and efficiency. However, controlling their speed remains a challenge, especially in small-scale applications without expensive systems. Therefore, a precise, affordable, and easy-to-implement motor control solution is needed. This study discusses the implementation of a three-phase induction motor speed control system using the LS G100 inverter and LS XBM-DR16S PLC through the Modbus RTU RS-485 communication protocol. The system is designed without additional expansion boards to simplify the circuit and reduce costs. The methodology used is an engineering and experimental approach, focusing on the measurement of motor electrical parameters such as actual speed (RPM), frequency, voltage, and current. Test results show that the system is capable of precisely controlling motor speed, with an average RPM accuracy of 99.6%, voltage accuracy of 97.2%, and current accuracy of 91.1%. The system has proven to be reliable and efficient for small to medium-scale industrial automation applications and facilitates real-time troubleshooting and monitoring through integrated data communication.
