System Dynamics Simulation Model to Increase Paddy Production for Food Security

Abstract

Background: Food security is a world problem that often affects developing countries, one of them in Indonesia. Along with the increasing population growth population in Indonesia, this will affect the level of demand for rice for food needs. The problem of rice consumption and its fulfillment is an important agenda. If Indonesia does not want to depend on rice imports, then paddy production must continue to be increased. Therefore, food availability in each region is maintained to realize food security. Objective: The purpose of this study is to analyze the factors that influence the increase paddy production in terms of cultivation and postharvest using a system dynamics model approach as the basis for policy strategy preparation.Methods: System Dynamics (SD) approach with the consideration that this framework offers the ability to study and manage complex feedback systems and the ability to model non-linear behavior. Then do a series of decision scenarios to get the best results using computer assistance.Results: Scenario results indicate that increasing paddy production to meet demand in Indonesia can be done by increasing the adoption of postharvest harvesting mechanisms coupled with the application of appropriate GAP (Good Agricultural Practice). It will increase paddy production in East Java so that it will make a large contribution to rice production in East Java.Conclusion: This research can be used to improve paddy production to food security by improving harvesting mechanisms. For further research, we can consider increasing rendement paddy in supporting increased rice production.

The Influence of Economic Development on the Wetland Conversion in Java-Bali

“…It means that food security may remain intact provided that the following measures are continuously taken: controlling wetland conversion, increasing agricultural productivity, upgrading irrigation system, improving milling yields of polished grain, etc. It concurs with Aprillya MR, et al (2019) who claim better rice harvesting procedures and increased milling yields will improve rice production which, in turn, will help food security. Rosyandi AN, et al (2019) add that farmers make significantly better income selling polished rice grains rather than unpolished rice kernels.…”

Model Sistem Dinamik Stok Beras untuk Mendukung Ketahanan Pangan Provinsi Bali

“…Menurut Aprillya et al (2019), faktor utama yang mempengaruhi produktivitas padi adalah varietas benih, ketersediaan air irigasi, pemupukan, dan serangan hama. Produktivitas padi tertinggi di Provinsi Bali pada tahun 2019 diraih oleh Kota Denpasar yaitu sebesar 7,453 ton/hektar (BPS, 2020).…”

Analisis Pengaruh Faktor-Faktor Produksi Terhadap Produksi Padi Anggota Kelompok Tani Margo Utomo Kecamatan Ungaran Timur Kabupaten Semarang

“…Penurunan produksi dan produktivitas tahun 2015 membuat petani rugi, maka dari itu perlu diketahui penyebab terjadinya penurunan produksi. Produksi padi dapat dipengaruhi oleh beberapa faktor produksi yaitu luas lahan, penggunaan benih, pestisida dan pupuk serta pencurahan tenaga kerja (Aprillya, Suryani, & Dzulkarnain, 2019;Bashir &Yuliana, 2019). Penggunaan input produksiapabila sudah optimal akan meningkat produksi padi maka dari itu petani perlu memahami cara mengelola input produksi padi sehingga hasil produk padi dapat sesuai dengan yang di harapkan oleh petani (Karmini, 2017;Ramachandra Reddy & Kishori, 2019) Tujuan dari penelitian yaitu menganalisis pengaruh penggunaan faktor produksi luas lahan, tenaga kerja, benih, pupuk urea dan pestisida terhadap produksi padi dan menganalisis tingkat efisiensi teknis dan efisiensi ekonomi penggunaan faktor produksi luas lahan, tenaga kerja, benih, pupuk urea dan pestisida pada usahatani padi di anggota Kelompok Tani Margo Utomo Desa Kalikayen Kecamatan Ungaran Timur Kabupaten Semarang.…”
