Abstract

The objective of this paper is to investigate the effect of porosity on the corrosion rate of aluminum foams as sacrificial anodes. An aluminum bar (6061 series) was cut to 19x19x13 mm. Then the aluminum was drilled to become an aluminum foam. A Carbon steel plate was cut to 40x 40x1 mm. The aluminum foam and the steel were connected by a bolt to become a galvanic couple. The galvanic couples were immersed in fresh water for variation times (32 hours, 168 hours, 335 hours, 504 hours and 672 hours). The temperature was 27 oC. The corrosion test was the weight loss method. The results. The corrosion rate of initial steel is 0.15 millimeter per year (mmy). The corrosion rate of steel decrease from 0.15 mmy to 0.015 + 0.02 mmy when using the aluminum foam as sacrificial anode. The corrosion rate of initial aluminum foam is 0.01 mmy. The corrosion rate of aluminum foam increases from 0.01 to 0.015 – 0.02 mm when used as sacrificial anode. Increasing the porosity of the anode will reduce the corrosion rate of the anode itself.

Abstract

Landslides are Indonesia's second most common disaster in the last ten years. Landslides cause losses, reaching hundreds of billions and threatening human safety. For this reason, it is necessary to take action to reduce the negative impact of landslides. Physical and non-physical mitigation can occur before, during, and after a disaster. The most essential thing in disaster mitigation is knowing the major factors that cause landslides. This research aims to analyze the major and minor factors that cause landslides using the Analytical Hierarchy Process (AHP) and the Likert scale. Respondents in this research are experts in disasters, especially landslides—respondents from universities in Indonesia, practitioners, and people involved in disaster mitigation. Validity and reliability tests were carried out on each question used in the questionnaire. The research results show that the landslide disaster was caused by a disruption in balance that occurred due to internal and external disturbance factors. The major external factors that cause slope failures are the cutting of hills and changes in land use to built-up areas. In contrast, the major internal factors that trigger landslides are heavy rainfall and steep topographic conditions. The results of this research in the form of weight and scoring values for each factor causing landslides can be used as a reference for mapping landslide areas to identify areas with the potential for landslides.

Abstract

West Sumatra Province, especially Padang City, is one of the earthquake-prone areas because it is located on the west coast of Sumatra, which is tectonically close to the subduction zone, namely the meeting zone or boundary between two tectonic plates where the movement of these two plates results in a large earthquake. As an area that is prone to earthquakes, knowledge about earthquake-resistant structures is very important. One method that is commonly used today is to carry out analysis to obtain the performance level of the structure. A 7-story government building located in an earthquake-prone area will be the object of this research. The building is made of concrete material, with a frame concept and is used for public purposes, so this structure's level of importance is high. This study examines the condition of a government building's resistance to seismic behavior. The method used is to look at the structural behavior of the 7-story building with pushover analysis. The pushover method is one method of the performance-based design concept. With the ATC-4o standard as a reference, the building is analyzed using the pushover method to understand its seismic behaviour. The results obtained indicate that the building is experiencing immediate occupancy conditions.

Abstract

In the manufacturing industry, specifically in automotive sector, musculoskeletal disorders (MSDs) account for 11.4% of all workplace injuries. This is primarily due to the high demand for increased production capacity. The process of assembling automotive parts involves manually organizing materials before they are sent to the assembly line. The handling of large material loads and repetitive movements during this kitting process can significantly increase the risk of MSDs. A study was conducted to examine the ergonomic risks associated with the kitting process in a manufacturing environment. The study utilized the Rapid Entire Body Assessment (REBA) method to evaluate kitting operators for potential musculoskeletal disorders (MSDs) related to lifting, carrying, and placing materials during the kitting process. Additionally, kitting operators completed the Nordic Body Map (NBM) questionnaire for self-assessment. According to the REBA results, lifting activities (11 points) posed the highest risk, followed by placing materials (7 points) and carrying materials (4 points). The NBM responses indicated complaints of pain in the hands, shoulders, and back, with NBM scores of 36 and 48 points, signifying a low risk. Immediate action is necessary to reduce MSD complaints among packaging operators based on hazard control analysis. Recommendations have been made for ergonomic interventions, including improving work postures, regulating loads through ergonomic training, utilizing assistive devices, and making workspace adjustments to minimize the risk of MSDs. By implementing appropriate interventions and preventive measures, the risk of MSDs among kitting operators can be reduced, while improving work safety, comfort, and maintaining productivity and process efficiency

Abstract

Changes to the halal logo's design occurred as a whole, both in terms of shape and colour, which are thought to refer to one culture. The new logo design is thought to prioritise creative writing in Arabic over halal writing. The Ministry of Religion, on the other hand, has explained a new design concept that is distinct and has a strong personality that embodies Indonesian values. According to the government, the modification to the Indonesian halal logo also signalled the transfer of authority to give halal certification from the Indonesian Ulema Council to the Halal Product Guarantee Organizing Agency (BPJPH. This study aims to identify Tanjungpura University students' perceptions of modifications to the new Halal logo design and to analyze student perceptions of adjustments to the new Halal logo using the mixing technique. The logo has six factors: original, legitimate, simple, memorable, easily connected with the organization, and easily adaptable for all visuals. Based on test results assisted by smartPLS 4.0, it shows a p-value ≤ 0.05. This signifies that the relationship between the variables is substantial, and the hypothesis derived from the relationship between the two variables is accepted. Meanwhile, the findings of qualitative testing employing interview methodologies revealed that 70% of respondents were intrigued by the logo. Research-based on interest variables reveals that 65% of respondents have halal awareness as a factor that emerges from within themselves. Examining these two components proves and validates the hypothesis results from quantitative testing.

Abstract

The condition of Special Capital Region of Jakarta (DKI Jakarta), as one of the economic centers in Indonesia, has a very high level of population mobility, both from within and from other cities around it. The existence of the Jakarta Mass Rapid Transit (Jakarta MRT) aims to provide guidelines for creating a city environment that is oriented towards humans as users and/or the public interest, with an emphasis on aspects of functional quality, visual quality and environmental quality. With the MRT Senayan, we can implement a good Transit Oriented Development (TOD) area with structured land use selection. This writing aims to identify the potential for functional characteristics in the Senayan MRT TOD area. Senayan MRT region has medium potential according to the major line since it has complete pedestrian amenities, crossovers, and a bicycle track. Senayan MRT station has also become a significant Transit Oriented Development (TOD) region, connecting numerous major areas in Jakarta, including Senayan, Gelora Bung Karno, Blok M, and the central city. Transit Oriented Development zones can help to alleviate some of the city's or area's problems when implemented correctly.

Abstract

YOLO (You Only Look Once) is a prominent deep learning model used in object detection due to its high detection accuracy and speed. Nonetheless, in detecting bull sperm, YOLOv7 Tiny performance suffers because of the unique characteristics of bull sperm: its tiny size and the large quantity of sperm. YOLOv7 Tiny's performance can be improved by adjusting based on its unique characteristics. This study proposes a modified YOLOv7 Tiny model to detect bull sperm with higher accuracy. The main objective of this research is to increase the accuracy of YOLOv7 Tiny in detecting and counting bull sperm. The YOLOv7 Tiny architecture will be modified based on the characteristics of the object to be detected, specifically bull sperm. Several architectural parts were deleted, the anchor box's size was changed, and the grid cell's size was changed. The omitted architecture parts are the ones used for detecting large and medium-sized objects. The anchor box and grid cell sizes will be altered to fit the size of the object. Accuracy is measured using mean average precision (mAP). The modified YOLOv7 Tiny will be evaluated in comparison to the original YOLOv7 Tiny. In our experiment, we produced 65.8 mAP with an inference time of 14.4 ms on the test dataset. When detecting bull sperm, the modified model is 1.3 points more accurate and 1.23x faster than YOLOv7 Tiny. The size of the modified model file is likewise decreased by 84.2%.

Abstract

Many road damages are caused by road construction that does not follow standards, so evaluating road conditions and choosing the appropriate asphalt for each state is essential. So, in this study, the asphalt mixture was modified using rubber asphalt with a percentage of rubber of 7% in the Hot Rolled Sheet-Wearing Course (HRS-WC). This study aimed to identify the effect of rubber asphalt on Marshall's characteristics and durability in HRS-WC. The method in this study is the Marshall Test and the calculation of the durability index on the test specimen with an immersion time of 0.5, 24, 72, and 168 hours at a temperature of 60°C. From the test results, the Optimum Asphalt Content (OAC) value of the rubber asphalt mixture was 7.13% with Marshall characteristic values of 4078.686 kg, flow 3.266 mm, MQ 1270.676 kg/mm, VMA 21.487%, VFB 71.983%, and VIM 6.062%. From the durability test results, the Residual Strength Index (RSI) value entered the specification only until the 24-hour immersion time with a value of 94.891%. The First Durability Index (FDI) and Second Durability Index (SDI) values are positive, where the mixture loses strength with increasing immersion time. It can be concluded that using rubber asphalt in HRS-WC is good enough for pavement because almost all Marshall characteristics were included in the specifications used. The stability value in the rubber asphalt mixture is higher than that of the pen—60/70 asphalt mixture. However, the level of durability of the rubber asphalt mixture is relatively low because it can only last up to 24 hours of immersion. Therefore, HRS-WC using rubber asphalt is unsuitable in areas with low groundwater levels or areas that often flood.

Abstract

The impact of installing a capacitor bank on the performance of an electrical system is evaluated through the analysis of changes in active power, reactive power, voltage, and power factors at various buses. The analysis indicates that the addition of the capacitor bank results in a significant increase in active power and a substantial reduction in reactive power. At Bus 1 (20 kV), active power increased from 648.93 kW to 687.38 kW, while reactive power decreased from 613.19 kVAR to 124.24 kVAR. At Bus 2 (0.4 kV), active power from 635.65 kW to 679.25 kW, and reactive power dropped from 560.59 kVAR to 92.046 kVAR. Voltage levels remained stable or slightly increased, and the power factor showed significant improvement, rising from 72.684% to 98.046% on Bus 1 and from 75.000% to 99.094% at Bus 2. Overall, the capacitor bank enhances system efficiency by optimizing power usage and reducing reactive power.
