Analisis Kondisi Iklim dan Pemanfaatannya untuk Penetapan Musim Tanam di Daerah Batabual Kabupaten Buru

The determination of the growing season is closely related with the climate change that occurs in a region The study aims to determine the trend of changing the growing season in the Batabual Area, changes in the growing season that occur due to changes in rainfall, and alternative planting patterns in Batabual region based on changes in the growing season that occur. Data analysis consisted of (1) determining the climatic conditions of the region using the Algebraic average method from monthly rainfall data from the Buru meteorological climate station for the last 30 years 1991-2020 and (2) determining the planting season using the FAO method (1978). The results showed that based on average rainfall data, the growing season lasted for 10 months and 19 days (November to September 19 of the following year).  However, if you use rainfall with a 75% chance of being exceeded, the growing season period only lasts for 8 months and 21 days (December – July 21 of the following year)

Analisis Musim Tanam dan Pengaturan Pola Tanam Tanaman Pangan pada Berbagai Kondisi Curah Hujan di Daerah Amahai Kabupaten Maluku Tengah

Cropping patterning is an farming practice to obtain maximum production taking into account climatic conditions, soil and types of crops cultivated. This research, which was carried out in the Amahai Region, aimed to: (i) describe extreme climate events and (ii) determine the growing season and cropping patterns of food crops based on the length of the growing season available in the region. The analytical methods used consisted of: (i) determining extreme rainfall based on BMKG standards and ENSO History data, (ii) determining the planting season using the FAO method, and determining cropping patterns in conditions of extreme rainfall. The results showed that a very extreme El Nino event caused a decrease in rainfall in the Amahai region by 1,444 mm or 54% of its normal condition, on whereas a very extreme La Nina event caused an increase in rainfall by 1,528 mm or 60% of its normal condition. The growing season in the Amahai region under conditions of average (normal) and La Nina rainfall is throughout the year (12 months), and under conditions of extreme El Nino rainfall, the growing season lasts for 8 months and 26 days, 96 days shorter than normal conditions.  In conditions of extreme El Nino rainfall, the cropping patterns that can be applied are sequential, monoculture, and polyculture/ intercropping
