| Abstrak (Bhs. Indonesia) | Komponen iklim mikro seperti suhu, kelembaban dan intesitas matahari mempunyai peranan penting dalam pertumbuhan tanaman. Pertumbuhan tanaman padi akan mengalami peningkatan mulai dari fase vegetatif hingga fase reproduksi dan berangsur-angsur menurun pada fase pematangan. Perubahan pada tiap fase pertumbuhan tersebut dapat mempengaruhi keadaan iklim mikro disekitar tanaman. Penelitian ini bertujuan untuk: (1) mengetahui hubungan antara LAI (Leaf Area Index) dengan suhu mikro kanopi tanaman dan (2) mengetahui hubungan antara LAI (Leaf Area Index) dengan suhu permukaan tanah. Penelitian ini dilaksanakan di screenhouse Laboratorium Teknologi Pertanian Universitas Jenderal Soedirman, Purwokerto, pada bulan Desember 2016 sampai April 2017. Pengambilan data dalam penelitian ini dilakukan pada 4 perlakuan yaitu: SRI Organik (SO), SRI Organik Arang (SOA), SRI Organik Kimia (SOK), dan SRI Kimia (SK). Hasil pengamatan selama penelitian memperlihatkan bahwa besarnya kanopi tanaman mempengaruhi nilai LAI dan iklim mikro bawah tanaman seperti suhu kanopi tanaman serta suhu tanah. Hasil penelitian menunjukkan adanya pengaruh perlakuan pupuk terhadap pertumbuhan tanaman padi. Peningkatan nilai LAI pada fase vegetatif dan mengalami penurunan pada fase pematangan hingga menjelang panen dipengaruhi oleh keadaan kanopi tanaman. Hasil perhitungan menunjukkan nilai LAI meningkat pada fase vegetatif untuk SO sebesar 1,63; SOA sebesar 2,03; SOK sebesar 2,90; dan SK sebesar 4,45. Nilai LAI berangsur-angsur menurun ketika mendekati masa panen. Pertumbuhan tanaman padi akan mempengaruhi keadaan iklim mikro disekitarnya seperti suhu kanopi serta penanaman padi metode SRI (System of Rice Intensification) dengan perlakuan pupuk yang berbeda mempengaruhi iklim mikro tanah seperti suhu tanah dan kadar air tanah. |

| Abtrak (Bhs. Inggris) | Microclimate components such as temperature, humidity and solar intensity have an important role in plant growth. Rice growth will increase from the vegetative phase to the reproductive phase and gradually decrease in the maturation phase. Changes in each of these growth phases may affect the microclimate state around the plant. The aim of this research is: (1) to know the relationship between LAI (Leaf Area Index) with microcurrent of plant canopy, (2) to know the relationship between LAI (Leaf Area Index) with ground surface temperature (3) to know relation between ground water content and soil temperature. This research held at a screen house in Laboratory of Bio-Environmental Management and Control Engineering, Jendral Soedirman University, from December 2016 to April 2017. The research use 4 treatments, those are: SRI-Organic (SO), SRI-Organic using charcoal as soil amandement (SOA), SRI-Organic with application of chemical fertilizer (SOK), and Inorganik-SRI with application of chemical fertilizer only (SK). The results showed the effect of fertilizer treatment on the growth of paddy plants. The increase in LAI values in the vegetative phase and decreased during the maturation phase until the time of harvest is influenced by the situation of plant canopy. The calculation results showed that LAI value increased in the vegetative phase for SO of 1.63; SOA of 2.03; SOK of 2.90; and SK of 4.45. The value of LAI gradually decreases as it approaches the harvest period. The growth of paddy plants will affect the condition of surrounding microclimate such as canopy temperature as well as paddy planting method of SRI (System of Rice Intensification) with different fertilizer treatment affecting soil microclimate such as soil temperature and soil moisture content. |
