Abstract

This study aims to identify and analyze the impact of the Galodo disaster in Sungai Jambu (Pariangan, Tanah Datar, West Sumatra) using PlanetScope satellite imagery. Galodo disasters, which are flash floods that transport materials such as soil and rocks, often occur in mountainous areas and cause significant damage to the environment and infrastructure. Located on the slopes of Mount Marapi, Sungai Jambu is one of the areas prone to galodo due to its geomorphology and high rainfall. The research methodology involved using PlanetScope images before and after the Galodo accident on May 13, 2024. Data processing included radiometric and geometric correction as well as image composite analysis to detect changes in land cover and river flow. The 3-2-1 and 4-3-2 composite images were used to detect changes in vegetation, stream conditions and degraded open land. The results showed significant changes in land cover and river flow due to the Galodo disaster, characterized by increased water turbidity and damaged vegetation. This study confirms the effectiveness of PlanetScope images in monitoring and identifying the impacts of the Galodo disaster. These findings provide important information for post-disaster mitigation and recovery planning and help identify areas that require restoration. Thus, the use of PlanetScope images can improve our understanding of environmental damage caused by disasters and support more effective and sustainable mitigation measures

Abstract

The spread of Covid-19 has led to the implementation of Large-Scale Social Restrictions (PSBB), social and physical distancing, to lockdowns to break the chain of spread of Covid-19, so this will definitely have an impact on the flow of loading and unloading of containers at Tanjung Emas Port, Semarang. This study aims to determine the flow of loading/unloading data and the influence of Covid-19 on the flow of loading/unloading containers at TPKS Semarang. This research is a type of correlation statistical analysis with a quantitative approach. The place and time of the research is at the Semarang Container Terminal in November 2022. The research instrument here is in the form of documentation. There are 3 data analysis techniques, namely descriptive statistical analysis, normality test, linearity test and Pearson product moment correlation test. The data analysis carried out showed that the results of the research from the descriptive statistical analysis test using the SPSS 26 application found that the average was 16,000 - 17,000 boxes/year. The normality test of all import and export data is normally distributed. The linearity test for all data gets linear results. Correlation statistical test with Pearson product moment showed that Covid-19 has no relationship with the flow of loading/unloading of imported and exported containers except for the flow of unloading/loading of imported containers in 2022.

Abstract

This study aims to design an efficient boat-pulling machine to support traditional fishermen at Pasie Katapiang Beach, Padang Pariaman. The research method employed is the design of the tool based on the principles of design engineering, involving a systematic process in creating a machine that can assist fishermen in the boat docking process more efficiently. Through calculations and planning, it was found that the force required to pull the fishermen's boat is 6,522.88 N, using a shaft made of ST 37 material with a diameter of 22.413 mm. The rotations generated on the transmission shaft are 2000 rpm, while on the wheel and drum shafts are 750 rpm and 500 rpm, respectively. The selection of a slip clutch with 2 bolts on the transmission shaft and the use of pillow block bearing ucp 206 ass 30 with specified bearing life estimates have been considered in the machine design. Practical test results indicate that the time required to reel or pull the boat is 0.98 minutes. In this research, the design of the boat-pulling machine meets operational needs. It has the potential to positively contribute to improving the work efficiency and welfare of traditional fishermen in the field

Abstract

Land Surface Temperature (LST) is widely utilized in current studies, particularly as an initial survey tool to assess geothermal activity in locations suspected to have geothermal sources. The research method involves geometric correction of Sentinel-3 imagery and conversion of temperature units from Fahrenheit (F) to Celsius (C) to ensure accuracy in temperature measurement. Image data processing from Sentinel-3, including thermal band analysis, is carried out to generate land surface temperature values. The field-measured temperatures are then compared to the land surface temperature data obtained through processing. The temperatures in the location, ranging from 23°C to 35°C, fall within the minimum geothermal temperature range, indicating potential geothermal activity. However, the LST values from the image data exhibit some differences compared to the on-site measurements. These discrepancies are categorized into classes I (23.7 – 24°C), II (24 – 24.3°C), and III (24.3 – 24.8°C), marked by red areas in the LST values. These discrepancies are attributed to various factors during image recording and processing, such as atmospheric interference and sensor calibration.
