Analisis Diagnosis Tingkat Kesehatan Mental Dengan Teknik Klasifikasi Algoritma C4.5
Get PDFMental health has become an increasingly important issue amid the growing pressures of modern life, particularly in the workplace. Job demands, performance targets, and the dynamics of social relationships at work can trigger stress that negatively affects employee productivity and well-being. However, low awareness and social stigma surrounding mental health issues often result in stress going undetected at an early stage. This study aims to identify employee stress levels at a company in Batam City using a data mining approach. Data were collected through the distribution of questionnaires based on the DASS-21 (Depression Anxiety Stress Scales), which measures three main aspects: stress, anxiety, and depression. The data were analyzed using the Python programming language, with stages including preprocessing, transformation of scale values into numerical form, and the construction of a classification model using the C4.5 algorithm (Decision Tree Classifier). The results showed that the classification model was able to identify stress levels with an accuracy of 67%. The best performance was observed in the moderate stress class (class 1), with a precision value of 0.71 and a recall of 0.79. In contrast, the classification performance for minority classes such as no stress (class 0) and severe stress (class 2) was relatively low. These findings suggest that the C4.5 algorithm is reasonably effective in recognizing dominant stress patterns but requires further data processing and class-balancing techniques to improve overall model performance. This study is expected to serve as a foundation for early detection and more accurate handling of workplace stres

PREDIKSI PENYAKIT DIABETES MENGGUNAKAN ALGORITMA REGRESI LOGISTIK
Get PDFThe annual count of individuals afflicted with diabetes is rising. As to a survey carried out by the International Diabetes Federation (IDF), the global diabetes population is approximated to be 537 million by 2021, and this number is projected to increase further to exceed 780 million by 2045. The study's primary goal is to diagnose and forecast whether or not a patient has diabetes. The approach makes use of logistic regression, a statistical tool for modelling individual classifications of diabetes presence or absence. According to the diabetes risk prediction results, 43% of respondents gave consideration to the condition. Consequently, it has been demonstrated that normalisation enhances the accuracy of diabetes risk prediction using logistic regression methods. Based on the variables included, it is anticipated that the predictions made by this model will serve as a guide for the general public in understanding healthy living and diabetes prevention.

PENERAPAN KLASIFIKASI CITRA PADA IDENTIFIKASI OBJEK DENGAN PAKAIAN SAFETY MENGGUNAKAN CONVOLUTIONAL NEURAL NETWORK DI PT JAYATAMA SAFETINDO.
Get PDFConstruction workers are essential to project execution but face high risks of workplace accidents, often caused by human factors. Advances in artificial intelligence, particularly image processing, provide opportunities to improve the detection of personal protective equipment (PPE), which is currently checked manually and inefficiently. PPE, such asgloves, helmets, and safety shoes, is vital for worker safety but is often neglected due to discomfort. This study uses Convolutional Neural Network (CNN) algorithms to classify images and verify PPE usage at construction sites. CNN processes spatial information through layers for feature extraction, dimension reduction, and classification. A previousstudy with Faster R-CNN achieved accuracies of 72.83% with TensorFlow and 88.07% with Faster R-CNN. Using a dataset of 200 images, this research, conducted at PT JAYATAMA SAFETINDO, applies Python and TensorFlow to improve PPE detection accuracy. The results aim to support safer workplaces, enhance productivity, and advance AI applications in safety and identification
SCROOGE’S MORAL LEDGER: A SEMIOTIC ANALYSIS OF ACCOUNTING IN CHARLES DICKENS’ A CHRISTMAS CAROL
Get PDFThis research examines the symbolism of accounting in Charles Dickens’ novel A Christmas Carol through the lens of Roland Barthes’ semiotic theory and critical accounting theory. The novel was selected for its rich use of economic terms, symbols, and metaphors that reflect the moral value system and capitalist structures of the 19th century. The research aims to identify accounting elements within the text, interpret their symbolic meanings, and analyze how Dickens' narrative critiques social inequality and capitalist ideology through the language of accounting. Employing a qualitative descriptive method and close reading technique, the research reveals that terms such as profit, debt, and penny, as well as symbols like chains, the banker’s book, and the ghostly figures, serve as metaphors for moral responsibility, spiritual burden, and a critique of dehumanization within the economic system. Through the integration of semiotics and critical accounting theory, the research concludes that accounting within the novel is far from neutral; it is ideologically charged, reproducing power relations and social disparity. Thus, A Christmas Carol emerges not merely as a literary text, but as a sharp reflection on social and moral practices in capitalist economies.Abstrak
Penelitian ini mengkaji simbolisme akuntansi dalam novel A Christmas Carol karya Charles Dickens melalui pendekatan semiotika Roland Barthes dan teori akuntansi kritis. Novel ini dipilih karena memuat berbagai istilah, simbol, dan metafora ekonomi yang merepresentasikan sistem nilai moral dan struktur kapitalisme abad ke-19. Penelitian ini bertujuan mengidentifikasi elemen akuntansi dalam teks, menafsirkan makna simboliknya, serta menganalisis bagaimana narasi Dickens mengkritik ketimpangan sosial dan ideologi kapitalis melalui bahasa akuntansi. Dengan menggunakan metode kualitatif deskriptif dan teknik close reading, ditemukan bahwa istilah seperti profit, debt, penny, hingga simbol seperti chain, banker’s book, dan tokoh-tokoh hantu berfungsi sebagai metafora untuk tanggung jawab moral, beban spiritual, serta kritik terhadap dehumanisasi dalam sistem ekonomi. Melalui integrasi semiotika dan teori akuntansi kritis, penelitian ini menyimpulkan bahwa akuntansi dalam novel tidak netral, melainkan sarat nilai ideologis yang mereproduksi relasi kuasa dan ketimpangan. Dengan demikian, A Christmas Carol tidak hanya menjadi teks sastra, tetapi juga refleksi tajam atas praktik sosial dan moral dalam ekonomi kapitalistik.
