Emisi polutan udara yang bersumber dari kebakaran hutan dan lahan serta dari transportasi di wilayah perkotaan menjadi perhatian baik bagi pemangku kepentingan dan masyarakat. Salah satu jenis polutan udara yang sering menjadi indikator utama adalah particulate matter 10 micron (PM10). Sedikitnya titik lokasi pengukuran konsentrasi PM10 menyebabkan ketersediaan data dan informasi polutan udara ini terbatas. Penelitian ini bertujuan untuk melakukan kajian terhadap penggunaan data dari model ECMWF sebagai prediksi untuk konsentrasi PM10 di dua lokasi, yaitu di Stasiun Pemantau Atmosfer Global Bukit Kototabang dan Kota Padang. Metode penelitian yang digunakan mengacu pada analisis data secara kuantitatif menggunakan metode korelasi dan statistik deskriptif. Hasil dari penelitian ini menunjukkan bahwa konsentrasi PM10 dengan menggunakan data ECMWF terhadap data observasi di kota Padang menunjukkan nilai selisih 25% (H-1), 20% (H-2), dan 17% (H-3), dan nilai prediksi terbaik adalah untuk data ECMWF pada H-3. Sementara itu nilai prediksi konsentrasi PM10 dengan menggunakan data ECMWF terhadap data observasi di Stasiun Pemantau Atmosfer Global Bukit Kototabang menunjukan nilai 12% (H-1), 23% (H-2), dan 24% (H-3). Hasil nilai prediksi terbaik konsentrasi PM10 di Stasiun Pemantau Atmosfer Global Bukit Kototabang adalah untuk data ECMWF pada H-1. Secara umum, konsentrasi PM10 dan hasil observasi menunjukkan profil yang sama, meskipun hasil dari ECMWF memberikan nilai konsentrasi yang berbeda di dua lokasi penelitian. Kata kunci: PM10, ECMWF, Bukit Kototabang, Kota Padang.

SummaryIt has been suggested that human platelets possess the ability to phagocytose particulate matter similar to the polymorphonuclear leukocyte. However some difference of opinion has arisen regarding this contention, particularly as differences have been demonstrated with regard to the observed metabolic changes occurring in platelets related to such a process.The experiments reported in this paper were designed to observe the aerobic and anaerobic metabolism in human platelets during and following interiorization of two different particles, viz. polystyrene latex and thorotrast. The results of these experiments show a marked difference between both types of particles with regard to observable metabolic changes despite the rapid interiorization of both types of material. Some alteration occurs in both aerobic and anaerobic metabolism a considerable time after interiorization of latex, whereas no alteration could be demonstrated after interiorization of thorotrast. It is suggested that the interiorization of particulate matter is by some process other than phagocytosis and that observed metabolic changes related to latex may be due to a release reaction.

Summary1. Infusions containing particulate matter, viz. whole amniotic fluid, amniotic fluid sediment, and glass beads, produce in dogs changes in both early and late phases of the clotting reaction. These changes are associated with the development of pulmonary hypertension.2. When dogs were given an active fibrinolysin followed by an infusion of whole amniotic fluid, the alterations in the clotting mechanism were either delayed or did not appear. No pulmonary hypertension developed in these animals.3. We infer that infusions containing particulate matter will produce in dogs both pulmonary hypertension and changes in the clotting mechanism. Although these are independent changes, both are as closely related to the damage to the pulmonary vessels as they are to the biological nature of the infusions.
