Kajian Pengawasan Unit Apron Movement Control terhadap Pemenuhan Standar Operasional Prosedur pada Area Apron di Bandar Udara Kalimarau Berau
Get PDFThis research evaluates how effectively the Apron Movement Control (AMC) Unit oversees adherence to Standard Operating Procedures (SOP) regarding ground handling operations and the use of Ground Support Equipment (GSE) at Kalimarau Airport. The study stems from frequent violations occurring in the apron area, which pose potential threats to aviation safety, with the goal of strengthening safety culture in airside operations.
Using a qualitative method, data were obtained through field observations, comprehensive interviews, and document analysis. The study focused on identifying recurring violations and assessing the current supervision system, with PR 21 Year 2023 serving as the primary guideline.
Findings reveal that AMC's oversight is still lacking, as shown by common breaches such as GSE operating over speed limits, parking equipment outside designated zones, unauthorized aircraft run-up activities, and failure to wear personal protective equipment (PPE). To overcome these problems, the study proposes improved surveillance using CCTV and GPS tracking, ongoing personnel training, and the implementation of a structured reward and sanction system to promote SOP adherence within the apron environment

OPTIMASI ALGORITMA RANDOM FOREST MENGGUNAKAN PSO UNTUK KLASIFIKASI KANKER PAYUDARA DENGAN CITRA MAMMOGRAMS
Get PDFThis research focuses on improving breast cancer classification through a combination of Random Forest and Particle Swarm Optimization (PSO) algorithms. Being the most common cancer among women worldwide, breast cancer requires an effective diagnostic screening method. Traditional methods such as manual examination and X-ray imaging are time-consuming and prone to errors. This research applies machine learning techniques, specifically Random Forest, for image classification based on mammograms. The methodology involves data collection, image preprocessing (including image resize, grayscale, and image segmentation using Sobel Edge Detection and Adaptive Thresholding), feature extraction via Local Binary Pattern (LBP), and classification via Random Forest optimized with PSO. PSO helps to identify the optimal hyperparameters and improves the accuracy of the Random Forest model. Model evaluation is done using confusion matrix which includes accuracy, precision, and recall values. The testing experiment showed that the PSO-optimized Random Forest model achieved an accuracy of 88.37%, outperforming the standard Random Forest model which achieved 86.05%. This shows that PSO significantly improves classification accuracy. This research contributes to the development of an easy-to-use diagnostic tool to assist specialists in accurately identifying breast cancer stages, and suggests future investigations should incorporate additional machine learning algorithms and utilize higher-standard DICOM images to improve training and testing data.Penelitian ini berfokus pada peningkatan klasifikasi kanker payudara melalui kombinasi algoritma Random Forest dan Particle Swarm Optimization (PSO).

Prevention paradox meets CPR Dilemma: A Covid Case
No full textFollowing the early March strict lockdown rules in Europe, we are now gradually moving towards more lenient rules, in which responsibility of individuals is required. Many of the rules are conditional on sustaining low pressure on the healthcare, and can be retracted whenever the national healthcare is (again) reaching its max capacity. Interestingly, these guidelines remain very abstract. For example, the Dutch government has changed the lockdown to “stay at home as much as you can” (Rijksoverheid, 2020). One of the most complex guidelines is “avoid crowds, leave whenever it becomes difficult to maintain 1.5 meter distance.”. The complexity lies in the fact that this creates a conflict between the individual and social decision making, in behavioural science known as the common pool resource dilemma. For instance, the beach on a hot day just last week is best to avoid to ensure no crowds, but as long as individuals expect the population to adhere to this reasoning, it is individually better to go to the beach. Indeed, at the first opportunity, this conflict manifests (“Veiligheidsberaad: ‘Niet allemaal dezelfde plek opzoeken,’” 2020). Persistence of this conflict can escalate to a general breach of the guideline by the whole population (described as ‘tragedy of the commons’). In this situation, however, the breach might not because of ill will, but because of failing to understand the individual thought-process. Guidelines should be tailored to this interpretation and understanding of the population in order to increase adherence to the guidelines, and reach the main goal
