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

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)

EVALUASI KINERJA MORFOMETRIK IKAN BUBARA, CARANX IQNOBILIS PADA KERAMBA JARING APUNG DI PERAIRAN TELUK AMBON DALAM

Monitoring dan evaluasi kinerja morfometrik ikan kuwe, Caranx iqnobilis pada sistem akuakultur masih kurang dan terbatas. Padahal melalui studi ini dapat mengevaluasi kinerja produksi akuakultur dapat terpantau. Penelitian ini bertujuan untuk mengevaluasi kinerja morfometrik ikan kuwe dalam sistem keramba jaring apung Penelitian ini berlangsung selama enam bulan dan bertempat di perairan teluk Ambon dalam. Analisis data dilakukan di Computational Biology Studio, MMSCE Universitas Pattmuar. Data morfometrik dilakukan secara digital menggunakan perangkat lunak Image-J. Analisis kinerja karakter menggunakan pendekatan kurva Bruri dan koefisien Bruri. Hasil penelitian menunjukkan bahwa proporsi karakter morfometrik ikan kuwe pada setiap lokasi budidaya di keramba jaring apung (KJA) dan yang dijadikan sebagai benchmarks berdasarkan rasio bobot tubuh, rasio panjang tubuh, dan rasio tinggi tubuh memiliki presentase karakter yang bervariasi. Kinerja morfometrik ikan Kuwe berdasarkan rasio bobot, panjang, dan tinggi tubuh masih menunjukkan kinerja yang baik namun memiliki keragaman yang bervariasi pada setiap populasi. Performa karakter morfometrik ikan kuwe pada setiap populasi berdasarkan kurva dan koefisien Bruri menunjukkan performa yang homogen atau merata pada setiap populasinya

Studi Tentang Mutu Biji Pala Dengan Pengeringan Matahari dan Pengasapan

The quality of nutmeg seeds is determined, among others, by their moisture content and the presence of aflatoxin contamination. To maintain quality, the moisture content of nutmeg seeds must be reduced to meet export standards. This can be achieved through sun drying or smoking. Aflatoxin is a mycotoxin produced by the Aspergillus fungi. The study aims to obtain nutmeg seeds with the appropriate moisture content according to the Indonesian National Standard (SNI) through sun drying and smoking methods. Also, it is to qualitatively identify the presence of aflatoxin in the nutmeg seeds. A total of 27 kg of nutmeg was divided into three treatment groups for drying and smoking. The drying and smoking treatments were arranged following a Randomized Block Design with three replications. Nutmeg essential oil was extracted using steam distillation. Subsequently, a qualitative identification of aflatoxin contamination was carried out using PDA media. The results showed that sun drying the nutmeg seeds for 72 hours resulted a moisture content of 7 - 8%. Meanwhile, the qualitative identification revealed the presence of Aspergillus niger, Penicillium sp, and Rhizopus stolonifer in the tested samples. No A. flavus, however, which is the main fungus responsible for aflatoxin production, was found in the results. Therefore, by drying the nutmeg seeds to a moisture content below 10%, the emergence of aflatoxin-causing fungi can be prevented

Analisis Kondisi Iklim dan Pemanfaatannya Untuk Penetapan Musim Tanam dan Pola Tanam Di Daerah Taniwel Kabupaten Seram Bagian Barat

A cropping pattern is an agricultural management activity that takes climate and soil conditions into account and seeks to achieve maximum results. Controlling cropping patterns is part of agricultural action planning to minimize the risk of crop failure. The purpose of this study is to (i) describe the climatic conditions in the Taniwell area, (ii) establish an effective growing season in the Taniwell area, and (iii) determine planting patterns for food crops in the Taniwell area. That's it. Length of growing season available. This study used his monthly climate data for 30 observation years from 1992 to 2021 from the Namlea Meteorological Station. Data analysis by following steps: (i) Analysis of rainfall (ii) Calculation of average rainfall (iii) Determination of rainfall with 75% probability (iv) Determination of planting season and planting pattern. The results showed that the effective growing season in the Taniwell area lasted 6 months and 24 days. It starts on December 1st and ends on June 24th.&nbsp

Evaluation of Land Suitability for Clove (Eugenia Aromantica L) and Nut-meg (Myristica Fragrans Houtt) in Nusalaut Island Central Maluku Regency

This research aimed to obtain land characters and qualities data and to determine land suitability for clove and nutmeg and their spatial distribution in Nusalaut Island, Central Maluku Regency. The results showed that the land suitability for clove are marginally suitable class (S3) with the coverage area is 1452.38 ha or 66.51%, and the limiting factors are water availability and nutrient retention (wa, nr) limiting factors and unsuitable class (N) of 731.52 ha or 33.50 %. While the land suitability for nutmeg are moderate suitable (S2) with root media and nutrient retention (rc, nr) limiting factors and the coverage area is 123.75 ha or 5.66%, S2nr of 409.93 ha or 18.77%, slope (S2eh) limiting factor with the coverage area is 918.7 ha or 42.1% and the unsuitable class (N) with the area of 731.52 ha or 33.50 %. The land suitability of the clove and nutmeg is located in the Other Used-Areas (APL) with the area of 2183.63 ha, while total land units in the study area is 2697 ha
