Abstract

The higher national rice demand encourages various efforts to increase rice production. This increase in rice production occurs in line with increasing public awareness of healthy foods, especially organic rice. Rice field management with an organic system is expected to provide a higher yield and quality of rice. This study aims to determine the effect of the long-time application of an organic rice management system on rice yield and quality. Descriptive exploratory research is supported by laboratory analysis of samples of organic rice plants with three periods (10 years, 7 years, and 4 years), semi-organic and conventional. The parameters observed were dry harvested grain, dry milled grain, the weight of 1000 grains, unfilled grain, protein content, amylum, amylopectin, and reducing sugar. The most prolonged organic rice field management with the application of 10 years gives better results with a protein content of 6.14%, amylum 71.71%, and amylopectin 49.35%. While the application of organic farming for 7 years gives the highest rice yield, the difference is not confirmed with the application of organic 10 years, with the weight of dry grain harvest 10.44 Mg ha-1, dry milled grain 8.15 10.44 Mg ha-1, the weight of 1000 grains 24 g, and unfilled grain 3.8%.

Abstract

The use of Trichoderma is one effort to manage healthy and environmentally friendly plants. This fertilizer is part of organic fertilizer; which farmers do not widely practice yet. This fertilizer has an impact that can increase nutrients and soil fertility. This study examined the impact of using Trichoderma in combination with NPK fertilizer on soil nutrient, nutrient uptake, and growth of corn plants. A Completely Randomized Block Design consisting nine treatments with three replicates was applied. The treatments were Control (A), standard NPK (Urea 350 kg ha-1, SP-36 200kg ha-1 and KCl 75kg ha-1) (B), ¼ NPK + 5 kg ha-1 Trichoderma (C), ½ NPK + 5 kg ha-1 Trichoderma (D), ¾ NPK + 5 kg ha-1 Trichoderma (E), 1 NPK + 5 kg ha-1 Trichoderma (F), ¾ NPK +1.25 kg ha-1 Trichoderma (G), ¾ NPK +2.5 kg ha-1 Trichoderma (H), ¾ NPK + 3.75 kg ha-1 Trichoderma (I). The results showed that NPK fertilizer accompanied by Trichoderma increased soil total N by 84.21%, available P by 36.25%, and available K by 142.22%. The same treatment also increased corn plants’ N, P, and K nutrients by 52.71%, 106%, and 61.53%. The growth of maize plants from applyingTrichoderma up to 5 kg ha-1 has not reduced the use of NPK fertilizer yet. However, applying Trichoderma could improve soil fertility.

Abstract

Lahan pasir pantai di Dusun Sogesanden, Desa Srigading, Kecamatan Sanden, Kabupaten Bantul, Daerah Istimewa Yogyakarta merupakan lahan sub-optimal yang memiliki keterbatasan biofisik lahan. Permasalahan utama budidaya di lahan pasir yaitu rendahnya efisiensi dan efektivitas penyiraman. Diperlukan sistem irigasi yang efisien dan efektif untuk menyediakan lengas yang cukup bagi tanaman. Tujuan penelitian ini adalah merakit dan mengimplementasikan teknologi automasi irigasi tetes pada lahan budidaya kacang tanah (Arachis hypogaea L.). Teknologi ini mampu memberikan air secara tepat kebutuhan dan sasaran yaitu pada zona perakaran tanaman. Metode yang digunakan adalah perakitan automasi sistem irigasi dengan alat monitoring kelembapan dan aplikasi penyiraman di lahan budidaya pasir pantai. Hasil penelitian menunjukkan bahwa sistem automasi irigasi telah berhasil dirakit dan diaplikasikan pada lahan pasir pantai, sistem berfungsi dengan baik. Sensor tanah mampu membaca kondisi lengas tanah dan mengirimkan data ke controller. Layar pada LCD menujukkan nilai kondisi lengas > 700 jika tanah dalam kondisi kering dan nilai lengas ≤420 jika tanah dalam kondisi basah. Keran otomatis akan membuka (>700) sehingga air dari tandon akan mengalir melalui selang menuju perakaran tanaman dan keran otomatis akan menutup dan menyetop aliran air dari tandon jika nilai lengas ≤420. Diperoleh efisiensi tenaga kerja siram mencapai 100% setelah menggunakan teknologi automasi irigasi irigasi tetes.

Abstract

Kebonagung Sub-district, Sidoharjo District, Wonogiri Regency is the Wonoagung Wonogiri Organic Farming Association (PPOWW) location. Mitra is an organization engaged in organic rice and cattle cultivation. The conversion of bovine dung into organic fertilizer, particularly liquid fertilizer containing biological agents, is one of the waste elimination strategies employed to prevent environmental contamination. The nutrient content of organic fertilizer material sources varies. Organic fertilizer of high quality conforms to the Standard for Organic Fertilizers established by the Ministry of Agriculture of the Republic of Indonesia. Only some producers are aware of the standard quality requirements for organic fertilizer. It is necessary to analyze the nutrient content of organic fertilizer products to determine whether the quality of organic fertilizer is excellent. A preliminary survey of partner conditions, preparation of materials (organic fertilizer), and analysis of fertilizer content are among the activities performed. The C/N ratio of organic fertilizer is 8.41, and its pH is 7.6. The analysis results indicate that the Wonoagung Wonogiri Organic Agriculture Association's organic fertilizer products meet the liquid organic fertilizer quality standards. This condition demonstrates that the raw materials used in organic fertilizer production are of high quality and that the appropriate procedures have been followed. Adding biological agents to the production of organic fertilizer can enhance the quality of the finished product.
