ABSTRAK Jagung merupakan komoditas pangan dominan di Pulau Kisar dan menjadi sumber pangan utama masyarakat. Pengusahaannya bersifat subsistem dan tradisional untuk memenuhi kebutuhan pangan rumah tangga petani dan tidak dikomersialkan, meskipun ada yang menjualnya dalam jumlah sangat terbatas jika ada kelebihan. Sistem pertanian lahan kering menetap dengan pola tanam polikultur pada satu lahan dengan kombinasi tanaman setahun dan tahunan. Tujuan penelitian ini untuk melihat tingkat keuntungan dan kelayakan serta keberlanjutan usahatani jagung di Pulau Kisar, menggunakan Metode Survei dengan teknik Stratifikasi Random Sampling. Hasil penelitian menunjukkan bahwa biaya produksi jagung di Pulau Kisar Kecamatan PP Terselatan Kabupaten Maluku Barat Daya terdiri dari komponen biaya tetap meliputi : biaya penyusutan alat dan biaya sewa lahan, biaya variabel meliputi : biaya saprodi dan biaya tenaga kerja. Biaya variabel memberikan kontribusi terbesar terhadap biaya produksi usahatani jagung. Usahatani jagung menguntungkan dan layak diusahakan, ditunjukkan oleh besarnya rata-rata nilai pendapatan Rp.4.488.617 yang diperoleh dibandingkan dengan rata-rata biaya yang dikeluarkan petani sebesar Rp.3.755.917 serta nilai BC rasio sebesar 1,20. Usahatani jagung memiliki keberlanjutan secara ekonomi, ekologi dan sosial.Kata kunci : jagung, usahatani, keuntungan, kelayakan, keberlanjutan
CORN FARMING ANALYSIS AND SUSTAINABILITY IN KISAR ISLAND, DISTRICT OF THE SOUTHEST ISLAND, SOUTHWEST MALUKU REGENCYABSTRACT Corn is the dominant crop commodity in Kisar Island and become staple food for the community. Corn farming are traditional and subsystems to meet farmers household food needs of farmers and not commercialized, even though they're sold in very limited numbers if there is an excess. The farming is carried out on permanent dry land by polyculture cropping pattern that is combination of annual and perrenial crops. This study aimed to examine the feasibility and profitability of corn farming in Kisar island, using survey methods with stratified random sampling technique. The results showed that the cost of corn production in Kisar Island, district of Southest Island in South West Maluku Regency is consisted of fixed cost and variable cost. The fixed cost components is including : equipment depreciation costs and land rent costs. The variable costs includes inputs costs and labor costs. Variable costs is the largest cost component for corn farming. Corn farming is profitable and viable, as indicated by the average revenue Rp. 4.488.617 compared to the average cost incurred by farmers Rp.3.755.917 and BC ratio of 1.20. Corn farming has economic, ecological, and social sustainability.
“…According to Devuyst, et al [4] cited by Tan et al [5], sustainability assessment is defined as "... a tool that can help decision makers and policy makers decide which actions they should or should not take in an attempt to make society more sustainable". The sustainability development has been based on three major focus areas: the economy, society, and the environment [6,7]. These dimensions have been more important for sustainability, and the majority of research studies have been conducted on these dimensions.…”
Global warming is one of the most important challenges nowadays. Sustainability practices and technologies have been proven to significantly reduce the amount of energy consumed and incur economic savings. Sustainability assessment tools and methods have been developed to support decision makers in evaluating the developments in sustainable technology. Several sustainability assessment tools and methods have been developed by fuzzy logic and neural network machine learning techniques. However, a combination of neural network and fuzzy logic, neuro-fuzzy, and the ensemble learning of this technique has been rarely explored when developing sustainability assessment methods. In addition, most of the methods developed in the literature solely rely on fuzzy logic. The main shortcoming of solely using the fuzzy logic rule-based technique is that it cannot automatically learn from the data. This problem of fuzzy logic has been solved by the use of neural networks in many real-world problems. The combination of these two techniques will take the advantages of both to precisely predict the output of a system. In addition, combining the outputs of several predictors can result in an improved accuracy in complex systems. This study accordingly aims to propose an accurate method for measuring countries' sustainability performance using a set of real-world data of the sustainability indicators. The adaptive neuro-fuzzy inference system (ANFIS) technique was used for discovering the fuzzy rules from data from 128 countries, and ensemble learning was used for measuring the countries' sustainability performance. The proposed method aims to provide the country rankings in term of sustainability. The results of this research show that the method has potential to be effectively implemented as a decision-making tool for measuring countries' sustainability performance.
