Abstract
Peningkatan jumlah penduduk dan kebutuhan pangan turut meningkatkan permintaan akan produksi beras. Namun, hasil panen padi yang menurun akibat berbagai faktor seperti kondisi iklim, kesehatan tanah, dan penggunaan pupuk yang kurang tepat belum dapat mencukupi kebutuhan masyarakat sehingga diperlukan upaya peningkatan produksi padi, salah satunya adalah dengan penambahan input pada lahan. Pemberian pupuk berimbang dan penggunaan dekomposer akan dapat meningkatkan kesehatan tanah dan ketersediaan hara bagi tanaman. Penggunaan dekomposer diduga dapat mempercepat laju dekomposisi bahan organik dan mampu meningkatkan kualitas fisik, kimia, maupun biologi tanah. Pemberian dosis rekomendasi pemupukan dapat dilakukan menggunakan teknologi digital seperti pemanfaatan citra pada penginderaan jauh. Dengan demikian, penelitian ini dilakukan untuk mengetahui dampak dari pengaplikasian dekomposer pada penerapan sistem rekomendasi pemupukan berbasis citra kamera multispektral terhadap sifat fisik tanah, pertumbuhan, dan hasil tanaman padi. Pelaksanaan kegiatan penelitian ini mulai pada bulan November 2021 hingga April 2022 pada lahan percobaan milik PT. Sang Hyang Seri di Desa Sukamandijaya, Kecamatan Ciasem, Kabupaten Subang, Jawa Barat. Penelitian dilakukan dengan 2 perlakuan yaitu perlakuan non dekomposer (P1) dan perlakuan dengan pengaplikasian dekomposer (P2) pada lahan pertanaman padi dengan Varietas Mekongga. Dekomposer yang digunakan adalah Petro Gladiator dengan kandungan mikroba Trichoderma sp., Bacillus sp., Streptomyces sp., dan Lactobacillus sp., yang diaplikasikan satu kali dengan dosis 5 liter ha-1 sebelum dilakukan penanaman. Larutan dekomposer disemprotkan pada petak perlakuan berukuran 29 m x 56 m sebanyak 480 ml dekomposer dengan air hingga 56 liter (56 ml m-2 ). Variabel bebas pada penelitian ini yaitu pemberian dekomposer, sedangkan variabel terikat pada penelitian ini yaitu pada tanaman padi yang meliputi tinggi tanaman, jumlah anakan, umur berbunga, jumlah anakan produktif, dan produktivitas, juga pada sifat fisik tanah (tekstur, berat isi, berat jenis, ruang pori total, kadar air pF 1, 2, dan 4,2 serta pori air tersedia), dan data tambahan berupa sifat kimia tanah (pH, N-Total, P-Tersedia, dan K-Potensial). Data tersebut kemudian dianalisis dengan uji T Tidak Berpasangan pada taraf 5% pada Microsoft Excel 2013. Hasil penelitian menunjukkan bahwa pengaplikasian dekomposer pada sistem rekomendasi pemupukan berbasis citra kamera multispektral dapat memperbaiki kondisi tanah meliputi perbaikan berat isi tanah, berat jenis tanah, ruang pori total tanah, kadar air pF 1, 2, dan 4,2, pori air tersedia tanah, kemudian pH tanah, kandungan P-Tersedia tanah, dan kandungan K-Potensial dalam tanah, serta tinggi tanaman padi.
English Abstract
The increase in population and food needs also increase the demand for rice production. However, the declining rice yields due to various factors such as climatic conditions, soil health, and the use of inappropriate fertilizers have not been able to meet the needs of the community so that efforts are needed to increase rice production, one of which is by adding inputs to the land. The application of balanced fertilizers and the use of decomposers will improve soil health and nutrient availability for plants. The use of decomposers is thought to be able to accelerate the rate of decomposition of organic matter and be able to improve the physical, chemical, and biological qualities of the soil. Fertilization recommendation dosage can be done using digital technology such as using remote sensing images. Thus, this study was conducted to determine the impact of the application of decomposers on the application of a fertilizer recommendation system based on multispectral camera images on soil physical properties, growth, and yield of rice plants. The implementation of this research activity starts from November 2021 to April 2022 at the experimental field owned by PT. Sang Hyang Seri in Sukamandijaya Village, Ciasem District, Subang Regency, West Java. The research was carried out with 2 treatments, namely the non-decomposer treatment (P1) and with application of the decomposer treatment (P2) on rice field with the Mekongga variety. The decomposer used was Petro Gladiator that containing Trichoderma sp., Bacillus sp., Streptomyces sp., and Lactobacillus sp., which was applied once at a dose of 5 liters ha-1 before planting. The decomposer solution was sprayed on a treatment plot measuring 29 m x 56 m about 480 ml of decomposer with up to 56 liters of water (56 ml m-2 ). The independent variable in this study was the provision of decomposers, while the dependent variable in this study was on rice plant like plant height, number of tillers, flowering age, number of productive tillers, and productivity, also on soil physical properties (texture, bulk density, specific gravity, pore space total, moisture content pF 1, 2, and 4.2 as well as available pore water), and additional data in the form of soil chemical properties (pH, N-Total, PAvailable, and K-Potential). The data was then analyzed by Unpaired T test at 5% level in Microsoft Excel 2013. The results showed that the application of decomposers on multispectral camera images based fertilization recommendation system can improve soil conditions including improvements in soil bulk density, soil particle density, soil total pore space, soil moisture content pF 1, 2, and 4.2, available pore water, then soil pH, soil P-Available content and K-Potential content in the soil, as well as plant height of rice.
