Abstract

Kecamatan Sirimau memiliki jumlah penduduk terbanyak di Kota Ambon yang berdampak pada kebutuhan terhadap lahan permukiman yang semakin tinggi meningkat, hal ini tentu akan mempengaruhi perubahan tutupan lahan yang tidak terkendali serta berdampak pada alih fungsi lahan dan kerusakan lingkungan. Penelitian ini bertujuan untuk untuk menganalisis perubahan tutupan lahan Kecamatan Sirimau pada tahun 2012, 2017 dan 2022, serta memprediksi tutupan lahan tahun 2031. Penelitian ini menggunakan metode Cellular Automata Markov Chains (CA-MC). Hasil penelitian menunjukan bahwa pada periode 2012-2031 luasan jenis tutupan lahan permukiman dan lahan terbuka terus bertambah seiring dengan bertambahnya jumlah penduduk dan tingginya kebutuhan akan lahan terbangun. Berbeda dengan tutupan lahan daerah pertanian dan bukan daerah pertanian yang mengalami penurunan luasan. Hasil penelitian diharapkan dapat dijadikan dasar dalam pengambilan kebijakan terkait penataan dan pemanfaatan ruang yang baik kedepannya

Abstract

Flood can be defined as the inundation or flow of water that cannot be contained and exceeds normal limits, resulting in damage to the environment and humans. An area is considered prone to floods if it experiences high rainfall intensity, has low soil capacity or saturated soil, impermeable surfaces, degraded forest conditions, and steep slopes in the upstream area. By using Geographic Information System (GIS), existing data and information can be integrated, and modeling can be easily conducted. Moreover, the tendency of rainfall patterns and the possibility of flooding can be analyzed. Therefore, predictions for flood occurrences and the resulting damages can be promptly determined. Ambon city is an area with a topography that includes flat land, hills, and steep slopes with gradients exceeding 20%. This condition allows the city's development to occupy flat areas, leading to a relatively high population density. On the other hand, limited flat land forces the population to settle on the outskirts of the city, including the slopes of hills and riverbanks.
