Judul: Analysis of the Role of the Internet of Things (IoT) in Production Efficiency in Carrot Farming in Gobleg Village Buleleng Regency
Abstrak: Desa Gobleg merupakan salah satu desa di Indonesia yang mengembangkan pertanian berbasis teknologi atau Internet of Things (IoT) secara mandiri. Penggunaan IoT pada usahatani hortikultura (wortel) di Desa Gobleg dapat menjadi solusi dalam mengefisienkan waktu dan tenaga kerja. Akan tetapi, masih belum semua petani usahatani hortikultra di Desa Gobleg yang belum memanfaatkan IoT tersebut. Penelitian ini akan membuktikan terkait perbandingan pendapatan dan efisiensi secara ekonomis dari kedua sistem usahatani wortel konvensional dan IoT. Metode yang digunakan dalam penilitian ini adalah analisis pendapatan dengan R/C rasio dan analisis efisiensi ekonomi dengan Data Envelopment Analyst (DEA) dengan model Constant Return to Scale (CRS). Hasil penelitian ini menujukkan bahwa tingkat pendapatan usahatani wortel dengan metode IoT lebih tinggi dengan nilai R/C rasio atas biaya total sebesar 1,82 dan usahatani konvensional sebesar 0,93. Nilai efisiensi secara ekonomi yang diperoleh oleh masing-masing jenis metode usahatani sudah berada pada kondisi yang efisien., Gobleg Village is one of the villages in Indonesia that independently develops technology-based agriculture or the Internet of Things (IoT). The use of IoT in horticultural farming (carrots) in Gobleg Village can be a solution to shorten time and labor. However, not all horticultural farmers in Gobleg Village have utilized the IoT. This study will prove the comparison of income and economic efficiency of the two conventional carrot farming systems and IoT. The method used in this study is income analysis with the R/C ratio and economic efficiency analysis with Data Envelopment Analyst (DEA) with the Constant Return to Scale (CRS) model. The results of this study indicate that the level of carrot farming income with the IoT method is higher with an R/C ratio value of 1.82 for total costs and conventional farming of 0.93. The economic efficiency value obtained by each type of farming method is already in an efficient condition.

Judul: Analisis Efisiensi Ekonomi Usahatani Tumpangsari Wortel di Desa Sukatani, Kecamatan Pacet, Kabupaten Cianjur
Abstrak: The agricultural sector is one sector which is still reliable, because it has an important role for the economic development of a nation. Based on the value of 2007-2010 Indonesian horticulture Gross Domestic Product (GDP), vegetables are the second largest contributor to GDP after fruit with average value of Rp 28,885 billion. One type of vegetable that has the greatest growth rate is carrots, with growth rate 5.05%. Carrot production in Indonesia from 2007-2010 tended to increase. Largest carrot production is from Cianjur with the amount of 34 559 tones, equivalent to 30.43% of the total production in West Java and also become the center of production of carrots. The purpose of this study was to identify the factors that affect the level of production and estimate the production of economic efficiency. The model analysis used in this study was Cobb Douglas function model with Ordinary Least Square method (OLS). Economic efficiency analysis performed using the ratio approach Marginal Product Value (NPM) with Sacrifice Marginal Cost (BKM). The analysis showed that the factors which significantly affect the influence the farm production of intercropping of carrots were seeds, organic fertilizer and urea fertilizer. Results of economic efficiency analysis showed that farming had not reached economic efficiency yet. It was shown from the ratio of the Marginal Product Value (NPM) with sacrifices Marginal Cost (BKM) were not equal with one. Based on the income analysis, intercropping farming of carrots was providing economic benefits for farmers. This was indicated by the value of the cash cost of revenues over one growing season was Rp 10 747 174.00/Ha and revenues over one growing season total cost was Rp 3 592 374.00/Ha.
