Abstract

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.

Abstract

ABSTRACTClove is one of the commodities that continually contributes to both income national and local levels, as export commodities or fulfills domestic demand. Clove developed at moluccas first in Indonesia, namely; Bacan, Makian, Moti, Ternate, and Tidore. Moluccas have cultivated clove for generations and have high diversity of clove genetic resources. Several famous indigenous cloves are AFO, Tibobo, Tauro, Sibela, Indari, Air mata, Dokiri, Daun Buntal, and others. In addition, there are clove cultivation, namely; Zanzibar, Siputih, Sikotok, and Ambon. Diversity of varieties and agro- ecological conditions makes Moluccas be largest production of clove after South Sulawesi. Due to various constraints, clove production  is  estimated  decreased.  This  is  due  to  lack  of rehabilitation of plants as the impact of low prices or lack of technology  introduction.  This  paper  describes  about  clove production in Maluku with and without rehabilitation. Based on the results of dynamic systems  model, clove production  was projected decline until 15 to 30 years. Efforts to maintain clove existence as clove producer and increase of productivity should be done  immediately  by  plant  rehabilitation  in  the  long  term. Rehabilitation efforts by replacing old plant and replacement 10% of degraded land per year will fulfill the cloves of demand whichincreased 1.5% per year. Plant rehabilitation must be accompanied with increasing productivity in the short term through fertilization to repair the damage crops after harvest.Keywords:  Cloves, crop area, rehabilitation, productivit ABSTRAKCengkeh  merupakan  salah  satu  komoditas  perkebunan  yang memberikan kontribusi terhadap pendapatan nasional maupun daerah secara berkelanjutan, baik sebagai komoditas ekspor maupun untuk memenuhi kebutuhan dalam negeri.

Abstract

Shallot is one of horticultural commodities with a high demand. Majority of shallots in Maluku are bought from Surabaya and Makasar. However, the government continuously does horticultural development in the center of shallot production. The objective of this study was to analize the competitiveness and comparativeness of farming between shallots which are cultivated by local farmer and shallots which are imported. There were three locations of research i.e., Maluku Tenggara, Seram Bagian Barat, and Maluku Tengah. Primary data were collected by quessioner and used purposive sampling method. Primary data were analyzed using policy analysis matrix. The results showed that shallot farming in Maluku has comparative and competitive advantages compared with imported shallots. Agricultural government policy effectively increases local farmer insentive. However, it shows a decreasing trend while increasing productivity of shallot. Shallot farming having production higher than 8 ton/ha need output subsidy to give price guarantee. Effort to increase shallot competitiveness is conducted by increasing productivity and developing a farmer institution to make a sustainable agricultural development. Keywords: shallot, competitiveness, competitive and comparative

Abstract

The upland rice-based cropping pattern is a form of double cropping or crop rotation in which upland rice as a basic commodity (base crop) which can be preceded or alternated with other food crops as a secondary crop. This study was conducted on dry land agro-ecosystems in the Tanimbar Islands Regency (West Southeast Maluku), from March to December 2017. This study was an adaptive research with a field experiment approach in farmer's land. The objective of this research was to obtain the most profitable cropping patterns, efficiency in land use and economically also has the highest net profit so it is appropriate to be recommended as a technology innovation for upland rice-based cropping patterns in dry land. The results showed that upland rice which was cultivated in multiple ways through intercropping or overlapped cropping, namely Introduced Cropping Pattern 1 (Upland Rice + Maize-Peanuts) and Introduced Cropping Pattern 2 (Upland Rice + Corn/Cassava-Green Beans-Peanuts) can increase land productivity (index planting of 222% and 288%, respectively) and farmers' income increased by 244-588% compared to upland rice grown in monoculture. Multiple cropping patterns can be recommended as a technology package for upland rice-based cropping patterns on dry land because of its efficiency in the use of production costs and land use. Furthermore, it gave the highest farm income of IDR63,933,100,-/ha/year with a net profit of IDR45,716,380,-/ha/year or IDR15,238,793,-/ha/ cropping season.

Abstract

ABSTRAKKebutuhan 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. Kata kunci: proyeksi, daya dukung pakan, sapi.FEED RESOURCES AND CATTLE POPULATION PROJECTION IN MALUKU PROVINCEABSTRACTThe beef demands on the country always increasing every year as growth as human population. The beef stock depending on population of cattle, so the beef stock and cattle population must balanced. The dynamics of cattle population supported by carrying capacity in every region, so the cattle population and feedstuff stock can be estimated. Availability of feedstuff stock in every year with an excess quantity in an area can support for increasing cattle population. The aim of research was to estimating and forecasting carrying capacity and cattle population based on time series data from 1997 until 2012. The result of estimating and forecasting regional feedstuff stock support for increasing cattle. 4 model of tren analyzation used are Least Square pola linear, Quadratic, exponential, dan moving average. First, describe the carrying capacity from agriculture waste in every region and beef cattle population, then tren models was decided. The results showed feed source projection still sufficient to 1.800.734 cattle. This indicated that feed availability is abundant because the cattle population projection reach only 96.343  in 2017.Keywords: beef cattle, carrying capacity, projection,

Abstract

Clove is one of the main commodity which known since the 16th century and it was the main reason why imperialist found Maluku as clove resources. In Maluku, clove change society as from era of sultanate, colonialism, and independence era. This paper reviews the clove competitiveness compared to other clove producing provinces in Indonesia after severalepoch, especially reform era. Agribusiness system approach was used to enumerate the competitiveness index in the ten largest clove producing province in Indonesia. Sustainability index was calculated with multidimensional scaling. Clove Maluku occupies high-middle group, means Maluku is one of largest clove producing with sustainability index is middle. The others province in the same group are North Sulawesi, Central Sulawesi, East Java, and West Java. South Sulawesi is the only one which occupies high-high group. Furthermore, the high-low group consist of Banten, Southeast Sulawesi, North Maluku, and Central Java. Clove competitiveness can increase with enlarging productive plant area and immature plant area, increase productivity and fertilizer distribution, and reduce damaged plant area.Keywords: Cloves, competitiveness, agribusiness system, sustainability index, multidimensional scaling  AbstrakCengkeh merupakan salah satu komoditas unggulan yang telah dikenal sejak abad 16 dan menjadi alasan utama mengapa kolonial menemukan Maluku sebagai asal tanaman tersebut.

Abstract

Ubi kayu termasuk komoditas tanaman pangan utama sebagai penghasil karbohidrat yang diusahakan di lahan kering. Budidaya di lahan kering mengakibatkan berhubungan langsung dengan perubahan curah hujan. Indonesia memiliki tiga tipe curah hujan yang berbeda; tipe ekuatorial, tipe monsun, dan tipe lokal. Tujuan penelitian ini untuk mengkaji pengaruh curah hujan terhadap produksi ubi kayu berdasarkan tipe curah hujan. Lokasi yang dipilih meliputi 7 provinsi yang terdiri dari Provinsi Sumatera Utara, Kalimantan Barat, dan Sulawesi Tengah sebagai perwakilan tipe curah hujan ekuatorial, Provinsi Jawa Timur, Sulawesi Selatan, dan Kalimantan Barat sebagai perwakilan tipe curah hujan monsun; dan Provinsi Maluku mewakili daerah tipe hujan lokal. Data sekunder yang digunakan meliputi data produksi, luas lahan, dan curah hujan. Data dianalisis menggunakan regresi panel dan uji one way anova. Hasil menunjukkan bahwa curah hujan berpengaruh secara signifikan terhadap produksi ubi kayu di ketiga daerah tipe curah hujan. Rata-rata perubahan curah hujan yang terjadi di wilayah lokal berbeda signifikan dibanding rata-rata perubahan produksi ubi kayu di wilayah tipe hujan monsun dan lokal. Sedangkan rata-rata perubahan produksi ubi kayu di wilayah monsun tidak berbeda nyata dibanding rata-rata perubahan produksi ubi kayu di wilayah ekuatorial.

Abstract

Upland rice has high potential development that causes the potential of dry land in Indonesia is quite large. However, the productivity of upland rice and its contribution to national paddy production is still low. Upland rice mostly is cultivated based on rainfall so productivity of upland rice depends on fluctuation of rainfall at the area. Theoretically, Indonesia has three different rainfall types, namely; equatorial, monsoonal, and local. This study aimed to identify the effect of rainfall on upland rice production. This study used secondary data consisted of upland rice yield, precipitation, and harvested area in 1990–2017. Data were analyzed by quadratic nonlinear regression and then It was analyzed by Mann-Whitney different test. Selected location were North Sumatera Province, West Kalimantan, Central Sulawesi, East Java, South Sulawesi, South Kalimantan, and Maluku. Results show that three rainfall area types statistically differences. Precipitation at Equatorial area influences upland rice yield by 3.15 tons. Furthermore, precipitation at monsoon and local area have effects on reducing production by -0.17 ton and -10.66 ton respectively. Keywords: nonlinear regression, precipitation, productivity, upland rice
