“…System dynamics is a simulation methodology introduced by Jay Forrester to understand, visualize and analyze complex dynamic feedback systems. System Dynamics is a unique method that use to help managers and decision makers in order to find the policies and decisions that benefit and could be implemented well in a certain period of time [15]. This research consists of 4 steps: data collection, analysis of existing condition, identification significant variable, design of computer model: Causal Loop Diagram (CLD) and base model development and perform the process simulation with scenarios development.…”

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.

“…Nur Hasan, et al (2015) dalam penelitiannya menyatakan bahwa kesenjangan antara produksi kedelai dan permintaan kedelai di Indonesia selama puluhan tahun memicu munculnya ketergantungan atas impor produk kedelai. Kenaikan populasi setiap tahun akan meningkatkan permintaan konsumsi kedelai untuk makanan.…”

ABSTRAKTujuan penelitian ini adalah 1) Untuk mengetahui faktor – faktor yangberpengaruh terhadap penawaran kedelai di Indonesia. 2) Untuk mengetahuifaktor – faktor yang berpengaruh terhadap permintaan kedelai di Indonesia. 3)Untuk memprediksi penawaran dan permintaan kedelai di Indonesia 32 tahunkedepan.Data yang digunakan ini adalah data Sekunder adalah data yang telahdikumpulkan oleh lembaga riset dan dipublikasikan kepada pengguna data. Datasekunder berasal dari situs internet, laporan penelitian, jurnal, dan data-data yangdiperoleh dari lembaga terkait seperti Badan Pusat Statistik (BPS). Pengelolahandata menggunakan nalisis regresi linier berganda menggunakan SPSS.Hasil analisis menunjukkan bahwa Faktor – faktor yang berpengaruhsignificant secara simultan terhadap penawaran kedelai di Indonesia adalah hargakedelai domestik, harga kedelai impor, harga jagung, luas lahan, dan kurs,sedangkan secara parsial faktor yang berpengaruh significant terhadap penawarankedelai adalah harga kedelai domestik dan luas lahan. Faktor – faktor yangberpengaruh significant secara simultan terhadap permintaan kedelai di Indonesiaadalah harga kedelai domestik, harga kedelai impor, harga jagung, tingkatpendapatan penduduk, dan jumlah penduduk, sedangkan secara parsial faktoryang berpengaruh significant terhadap permintaan kedelai adalah tingkatpendapatan dan jumlah penduduk. Prediksi permintaan dan penawaran kedelai diIndonesia selama 12 tahun kedepan mengalami penurunan tiap tahunnya hinggatahun 2031. Pada tahun 2031 angka penawaran dan permintaan memilikikesamaan data.Kata kunci : Analisis Trend, Penawaran dan Permintaan, Kedelai Indonesia.

“…East Java is one of Indonesia's soybean [Glycine max (L.) Merrill] largest producer with high levels of selfsufficiency (Zainuri et al 2015;Hasan et al 2015;Putra et al 2017). Statistics Indonesia (2016) reported that 35% or 344.99 thousands of tons of the total soybean production in 2015 (963.18 thousands of tons) originated from East Java.…”

Abstract. Astriani M, Zubaidah S, Abadi AL, Suarsini E. 2020. Pseudomonas plecoglossicida as a novel bacterium for phosphate solubilizing and indole-3-acetic acid-producing from soybean rhizospheric soils of East Java, Indonesia. Biodiversitas 21: 578-586. The use of synthetic fertilizers to grow soybean (Glycine max (L.) Merrill) in a long time, can increase the risk of environmental damage. Therefore, the current study aimed to find phosphate solubilizing bacteria that can produce indole-3-acetic acid (IAA) hormone to minimize the use of chemical fertilizers. Superior isolates selected through characterization of phosphate solubilization activity on Pikovskaya medium, screening of IAA producing bacteria, quantitative estimation of phosphate solubilizing activity using a spectrophotometer, hypersensitivity assay, antagonist within isolate assay, and molecular identification of selected bacterial isolates using 16S rRNA sequencing with primer forward 63f and primer reverse 1387r. Among the isolated bacteria, isolate Arj8 showed the highest phosphate solubilizing activity and IAA production. Molecular identification indicated that isolate Arj8 shared 100% similarity with Pseudomonas plecoglossicida. The highest phosphate solubilizing activity (75.39 mg/L) and IAA production (38.89 ppm) recorded on day-3. Multiple potentialities of P. plecoglossicida as phosphate solubilizing and IAA producing bacterium are a novel finding in the development of bioinoculants as bio-fertilizers that can reduce dependency on synthetic chemical fertilizers.
