Abstract

Penelitian ini bertujuan untuk mengkaji hubungan antara indeks pengindraan jauh (Burn Area Index/BAI, Normalized Difference Vegetation Index/NDVI, dan Enhanced Vegetation Index/EVI) dengan tingkat pencemaran udara, khususnya konsentrasi PM2.5, di kota Jakarta pasca pandemi. Data diambil dari berbagai stasiun pemantau kualitas udara (SPKUA) di Jakarta selama tahun 2022. Hasil analisis menunjukkan variasi signifikan dalam konsentrasi PM2.5 yang berkaitan erat dengan fluktuasi BAI, NDVI, dan EVI. Peningkatan BAI selama musim kemarau bertepatan dengan peningkatan konsentrasi PM2.5, menandakan aktivitas kebakaran yang lebih intensif. Sebaliknya, NDVI dan EVI yang lebih tinggi selama musim penghujan berkorelasi dengan penurunan konsentrasi PM2.5, menunjukkan kondisi vegetasi yang lebih baik dapat membantu mengurangi polusi udara. Analisis Principal Component Analysis (PCA) lebih lanjut mengungkapkan bahwa bulan-bulan dengan karakteristik musim yang sama memiliki pola pencemaran udara dan indeks vegetasi yang serupa. Temuan ini menekankan pentingnya strategi mitigasi polusi udara dan manajemen lingkungan yang tepat untuk meningkatkan kualitas udara dan kesehatan lingkungan di Jakarta.

Abstract

Fluid flowing in a cross-section of a channel follows the law of continuity, namely the mass rate of fluid entering will be the same as the mass rate of fluid leaving. One of the applications of fluid flow is in human blood flow. Blood flow is controlled by the heart which functions to pump blood to and from the heart. The flow of blood entering and leaving the heart is determined by the cross-sectional area of the channel and the speed of blood flow through the heart. The speed of blood flow in the heart consists of two speeds, namely the systolic speed when blood leaves the heart and the diastolic speed when blood enters the heart. So that the volume in the heart can be observed changes over time. By creating a simulation using the MATLAB programming language, the difference between normal heart volume and problematic heart volume can be known. A program called reservoir and cardiac based on graphical user interface was created to determine the volume of fluid in the reservoir at any time and compare the volume of fluid in normal and abnormal hearts concerning time in 1 systole-diastole cycle.
