Abstract

Pati Regency is one of the largest rice-producing areas nationwide. However, data on the productivity of rice plants have been inadequate. So it appears the problem, 1) how the productivity of rice and how to estimate productivity of rice in support of food self-sufficiency program in Pati District? Population rice area Pati regency with Sample 85 points based on the interpretation of NDVI. The sampling method is simple random sampling. The first variable is productivity of paddy and the second variable is rice productivity estimates. The research instrument used questionnaire. Data analysis using the digital image interpretation technique and quantitative descriptive. Comparing the results mean produtivitas rice by BPS with the results of the study (2014) 5.43 with 5.5 tons / ha, the difference of 0.07 tons / ha. Among the data DISPERTANAK with the results of the study (2015) 109480 with 106,188.62 ha / year. There is a difference of 3.00%. So that remote sensing methods utilizing NDVI value in rice plants can be used to estimate the harvest area.

Abstract

Alih fungsi lahan pertanian ke non pertanian menjadi permasalahan di kawasan pinggiran perkotaan. Alih fungsi lahan ini disebabkan land rent lahan pertanian tidak menguntungkan dibandingkan jika dibandingkan dengan lahan komersil. Jika kondisi ini terus berlanjut maka akan mengancam ketahanan pangan suatu wilayah. Penelitian ini bertujuan untuk memodelkan penentuan kawasan sawah berkelanjutan berdasarkan analisis spasial dan teknik penginderaan jauh. Analisis yang digunakan meliputi analisis interpretasi citra, Geography Information System (GIS), analisis statistik, dan analisis prediksi ketersediaan lahan sawah. Penelitian ini dilakukan di Kabupaten Semarang dengan perkembangan perkotaan yang cepat. Variabel dalam menyusun model kawasan sawah berkelanjutan ini terdiri dari variabel produktivitas padi, kesesuaian lahan pertanian, intensitas panen, dan serta proyeksi arah perkembangan perkotaan. Hasil analisis produktivitas tanaman menghasilkan persamaan statistik produktiivtas (Ton/Ha) = 3,795 (NDVI) + 3,773 dan nilai koefisiennya sebesar 0,85. Terdapat selisih antara data dinas dengan data peneliti sebesar 10% dari luas lahan pertanian eksisiting. Selisish luas ini dikarenakan perbedaan skala peta, proses analisis, dan metode yang digunakan. Berdasarkan hasil analisis dan pembahasan maka dapat disimpulkan bahwa lahan sawah berkelanjutan ketersediannya mulai berkurang. Sehingga perlu adanya ketegasan pemerintah daerah dalam menjaga ketersedian lahan sawah.
