Abstract

Pada artikel ini, dilakukan identifikasi Mesoscale Convective Complex (MCC) di wilayah Tual. MCC adalah sistem konveksi awan skala-meso yang dicirikan oleh bentuk pola besar, berdurasi panjang, dan semi-melingkar. Keberadaan MCC dapat mengakibatkan hujan lebat dan berdurasi panjang serta dapat mengakibatkan banjir. MCC dideteksi menggunakan citra satelit kanal inframerah dengan algoritma yang dibangun berdasarkan karakteristik dari MCC berupa tutupan awan, eksentrisitas, dan durasi keberadaan awan. Hasil dari penelitian ini menunujukan bahwa hujan lebat pada tanggal 18 Januari 2019 di wilayah Tual tercatat 74 mm dalam sehari terjadi akibat adanya MCC pada wilayah tersebut. Hasil akhir dari analisis algoritma pengolah citra awan berbasis data satelit pada studi kasus mampu menghasilkan koordinat lintang dan bujur lokasi MCC saat fase tumbuh, matang dan punah, yang muncul di wilayah Tual.

Abstract

Research on surface wind patterns has been carried out in an effort to minimize aircraft accidents at Sultan Syarif Kasim II Airport Pekanbaru, Riau. Wind direction and speed data were obtained from synoptic observations of the Syarif Kasim II Pekanbaru Meteorological Station from January to December during 1991 - 2020 (for the last 29 years). The data is then processed using the WRPLOT (Wind Rose Plots for Meteorological Data) application which can show the direction and difference in the magnitude of the wind speed and produce an image of the wind pattern in the form of a wind rose diagram. From the results of this writing, it is known that the dominant wind blows from the south (157 - 202°) with a percentage of 27.18%, then followed by the dominant wind blowing from the Northwest (292 - 337°) with a percentage of 14.68% and then the dominant wind direction from the Southeast (112 - 157°) with a percentage of 9.60%. The dominant wind speed is 6 – 9 knots with a percentage of 48.01%, then dominant with a speed of 3 – 6 knots with a percentage of 34.15%, and calms wind speed with a percentage of 7.23%. The conclusion of this paper is that the condition of the wind direction and speed at Sultan Syarif Kasim II Airport Pekanbaru is still a safe category for the takeoff and landing process.
