Abstract

Dynamic systems are a modeling approach to understanding the behavior of complex systems that change over time through cause-and-effect relationships between variables. In agricultural practice, fertilization is an important part of crop care, where some of the need for chemical fertilizers is met through government subsidies. However, the remaining needs must be met with high-priced non-subsidized fertilizers, resulting in increased operational costs. This condition also occurs in Gombang Village, one of the villages located in Pakel District, Tulungagung Regency, which faces similar challenges in managing agricultural costs, so the dynamic systems approach is relevant to analyzing the effectiveness of fertilizer use in increasing farmer profitability in the area. This dynamic system is carried out with the help of STELLA software, STELLA is used to design a strategy to increase profitability by compiling two scenarios. The first scenario, the use of superior seeds increases the average profitability by 31,271,686,263. The second scenario, the use of semi-organic fertilizers increases the average profitability by 38,494,816,533.

Abstract

Analisis faktor-faktor yang mempengaruhi produktivitas pertanian padi dilakukan dengan menggunakan pendekatan Partial Least Squares Structural Equation Modeling (SmartPLS). Observasi dilakukan dengan penyebaran kuesioner kepada petani di Desa Senjayan, Kabupaten Nganjuk untuk mengidentifikasi hubungan kausal antar variabel. Hasil outer model menunjukkan bahwa sebagian besar indikator valid dan reliable, kecuali A4, B1, B2, dan B3. Secara struktural variabel Person pada tingkat pendidikan (A2) terbukti berpengaruh secara signifikan terhadap adaptasi teknologi (A3) yang kemudian berkontribusi pada peningkatan efisiensi biaya operasional. Nilai R-square sebesar 0,682 mengindikasikan bahwa model mampu menjelaskan 68,2% variabilitas profitabilitas petani. Dengan demikian penelitian ini bertujuan untuk meningkatkan produktivitas pertanian khususnya pada tanaman pangan padi dengan pendekatan SmartPLS efektif digunakan untuk memetakan dan menganlisis faktor-faktor utama dalam pengembangan strategi dan pengambilan keputusan yang tepat untuk pertanian secara berkelanjutan.

Abstract

Agriculture is a crucial sector in Tampingmojo Village, where approximately 60.94% of the area comprises rice fields. However, declining crop productivity each year due to factors like fertilizer use, seed quality, and cultivation practices poses a threat to local food security. This research aims to formulate an optimal scenario model to enhance farmer productivity and profits using a dynamic systems approach. The model was developed through stages including CLD and SFD construction, validation, sensitivity analysis, scenario establishment, and selection of the best scenario. Fertilizer and seed variables were prioritized due to their significant impact on productivity and profit. Historical data from 2019–2023 served as the base model for validation and testing. Simulation using STELLA revealed that Scenario 3, applying optimal doses of urea and phonska combined with organic fertilizer substitution, is the most effective. This scenario increased productivity by 18.10% (Inpari, MT 1), 19.95% (Ciherang, MT 2), and 21.94% (Pioneer, MT 2 & 3), while raising profits by 78.72% (Inpari, MT 1 & 2) and 63.73% (Bisi, MT 2 & 3) compared to existing conditions. Thus, this scenario is recommended as a policy direction to support improved productivity, farmer income, and strengthen local food security.

Abstract

Blitar merupakan kabupaten penghasil bahan pangan yang aktif di Provinsi Jawa Timur. Salah satu kecamatan yang turut berkontribusi dalam penghasil bahan pangan ialah Kecamatan Talun, khususnya Desa Bendosewu. Mayoritas petani pada desa ini menanam padi, jagung, dan cabai rawit. Seiring dengan bertambahnya penduduk, kebutuhan akan pangan juga akan meningkat. Hal ini akan menjadi tantangan bagi masa yang akan datang. Ketahanan pangan berkelanjutan dapat menerapkan mendefinisikan melalui pendekatan Triple Bottom Line (People, Planet, Profit). Penelitian ini bertujuan untuk membuat skenario model sistem dinamis dengan stella. Dengan metode sistem dinamis akan diketahui skenario yang paling optimal dari faktor yang paling berpengaruh yang dapat meningkatkan profit petani di Desa Bendosewu. Skenario dapat digunakan sebagai pertimbangan bagi stakeholder  untuk meningkatkan pendapatan  petani dan tercapainya ketahanan pangan yang berkelanjutan. Pada Desa Bendosewu, rata-rata keuntungan awal sebesar Rp.45.074.170.765. Skenario usia petani dengan adaptasi teknologi mampu meningkatkan sebesar 1,437%, penggunaan pupuk sebesar 18,654%, dan penggunaan jenis bibit jagung sebesar 8,916%. Skenario paling optimal adalah skenario gabungan dari keselurahan faktor dengan persentase sebesar 26,946%.
