Abstract

Background: Typhus is a disease caused by Salmonella typhi, Salmonella paratyphi A Salmonella parathypi B, dan Salmonella paratyphi C bacteria that attacks digestive tract and caused infection in small intestine. The common test that performed in the laboratory is widal test. The result reading of the widal test still processed manually with looking the turbidity caused by the agglutination. Aim: The research was made to decrease human error by creating a program based on artificial neural network (ANN) with learning vector quantization (LVQ) method. Method: Input of this program is image of blood serum that has reacted with widal reagen. Image procesing start with grayscaling, filtering, and thresholding. Result: Output of this program is divided into two classes, normal and typhus detected. Conclusion: From this experiment result that using 24 testing data, gives the accuracy of this program 95.833% with 1 error result from 24 testing data.

Abstract

Perkembangan teknologi finansial telah memberikan kemudahan akses layanan keuangan bagi masyarakat, namun di sisi lain turut meningkatkan risiko maraknya praktik pinjaman online ilegal. Rendahnya tingkat literasi keuangan menyebabkan masyarakat rentan terjebak dalam pinjaman berbunga tinggi, penagihan tidak etis, serta tekanan psikologis. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan pemahaman dan kesadaran warga RW 01 Kelurahan Cipondoh, Kota Tangerang, terhadap bahaya pinjaman online ilegal serta mendorong perilaku keuangan yang lebih bijak. Metode pelaksanaan meliputi penyuluhan, diskusi interaktif, dan simulasi perencanaan keuangan keluarga. Evaluasi dilakukan melalui pre-test dan post-test untuk mengukur peningkatan pemahaman peserta. Hasil kegiatan menunjukkan adanya peningkatan pemahaman yang signifikan, dari 42% sebelum kegiatan menjadi 85% setelah sosialisasi. Temuan ini menunjukkan bahwa edukasi literasi keuangan berbasis komunitas efektif sebagai strategi preventif dalam menekan praktik pinjaman online ilegal di masyarakat.
