Pengaruh Perubahan Iklim terhadap Produksi Tanaman Pangan di Provinsi Maluku

This study was aimed to determine the impact of climate change on food crops performance in the Maluku province, based on the climatological data from 1995 to 2012, and to find out crop commodities that are adaptable to climate change. This study used four models of trend analysis: linear least square pattern, quadratic, exponential, and moving averages. The results of forecasting were used to estimate food crop production in the year of climate change to determine the impact of climate change on crop production. Results showed that soybean was the most sensitive crop to climate change, it had the biggest impact on production, yield declined on both El Nino (10.7%) and La Nina (11.4%). Paddy which is generally cultivated on the wetlands, El Nino had the smallest effect on a decrease of production of 2.9% and 2.4% increased on the La Nina. Corn production decreased 7.4% on the El Nino and 3.9% increased during the La Nina. Sweet potatoes was the most resistant crop to climate change, the impact was increased production by 2.5% during El Nino. To reduce the impacts of climate changes could be done through some efforts, namely: (1) to identify areas of potential drought, floods, pests and diseases endemic based on climate and soil conditions, (2) to develop prediction techniques, based on weather and climate forecasts to provide early warning to farmers, (3) to prepare and disseminate a package of technology which is able to withstand the adverse conditions of the El Nino and La Nina, including varieties, pest and disease prevention, and production inputs which are easily obtained by farmers, (4) to improve irrigation and drainage channels, mainly on the paddy fields to increase production capacity and to prevent crop failure during the dry season.

Proyeksi Daya Dukung Pakan dan Populasi Sapi di Provinsi Maluku

Kebutuhan masyarakat akan daging sapi selalu meningkat setiap tahun seiring dengan pertambahan jumlah penduduk. Dalam hal ini, ketersediaan daging sapi sangat bergantung terhadap populasi sapi, sehingga harus seimbang antara kebutuhan daging sapi dan populasi sapi. Dinamika populasi sapi didukung oleh ketersediaan pakan dalam wilayah tersebut, sehingga proyeksi dugaan antara populasi sapi dan ketersediaan pakan dapat diramalkan. Ketersediaan pakan selama 1 tahun dengan kuantitas yang berlebih dalam suatu wilayah mendukung untuk peningkatan kapasitas populasi sapi. Penelitian ini bertujuan untuk melakukan pendugaan dan peramalan berdasarkan data runtun waktu dari tahun 1997 sampai dengan tahun 2012 terhadap peubah daya dukung pakan dan peubah populasi ternak sapi. Hasil ramalan dari kedua peubah tersebut digunakan untuk melakukan peramalan kemampuan daya dukung pakan terhadap kapasitas peningkatan populasi ternak sapi. Penelitian ini menggunakan empat model analisis tren yakni; Least Square pola linear, Quadratic, exponential, dan moving average. Adapan tahapannya adalah mendeskripsikan pola daya dukung pakan dan populasi sapi, penentuan model tren, pemilihan model yang sesuai, dan melakukan pendugaan atau peramalan. Hasil menunjukkan bahwa dugaan sumber daya dukung pakan masih memenuhi kebutuhan populasi sapi sampai 1.800.734 ekor. Hal ini menandakan bahwa ketersediaan pakan di Provinsi Maluku melimpah karena prediksi populasi ternak sapi hanya mencapai 96.343 ekor di tahun 2017.

Use of Carotenogenic Neurospora in Fermentation of Agricultural Byproduct for Poultry Feed

Agricultural byproduct is biomass that potential to partly subtitute the conventional feed. However, there are some constraints such as high fiber, low protein and carotene contents. One of the efforts to improve the nutritive value of agricultural byproduct is fermentation using carotenogenic Neurospora. This fungi easily and readily grows on substrate fermented in aerobic condition. Neurospora fermentation is able to reduce crude fiber, to increase crude protein and carotene content of substrate. Utilization of Neurospora fermented product as poultry feed ingredients increased productivity and product quality more efficiently.
