Marlina et al, 2018. Utilization of Various Types of Biofertilizer on the Production of Shallots (Allium ascalonicum L.) in overflow type C Tidal Soils from Banyuurip. JLSO 7(1):Tidal land has considerable potential to be used as agricultural land, one of which is for shallot, but the obstacles faced in this tidal land are high soil acidity and low soil fertility. Therefore, to increase the production of onion plants can be given biological organic fertilizer. This study aimed to analyze the right type of biological organic fertilizer in increasing the production of shallots. This research was carried out at the Greenhouse in Palembang. The design used was Factorial Randomized Completely Block Design with consisted of 4 treatment factors with 6 replications for each treatment. The first factor was control (O0), the second factor was biofertilizer enriched with Azospirillum (O1) bacteria, the third factor was biofertilizer enriched with phosphate solvent bacteria (BPF) (O2), and the fourth factor was biofertilizers enriched with Azospirillum and BPF bacteria. The results showed that the treatment of Azospirillum and BPF-enriched biofertilizers gave the best production per hill of onion by 85.33 g.
Organic fertilizers are fertilizers that primarily consist of organic materials derived from plant or animal residues converted in solid or liquid form. Household waste, especially vegetable waste, is usually dumped directly into the environment, even though this waste can still be used, for example, made as liquid organic fertilizer by utilizing local microorganisms (MOL). The mole contains micro and macronutrients and contains bacteria that can decompose organic matter. This Community Service aims to provide motivation and knowledge, and skills to the community about the technique of making liquid organic fertilizer from household waste by utilizing local microorganisms. Community Service held in Sungai Pangeran Village, Ilir Timur I District, Palembang City, on February 19, 2019. The method used was counseling and training participants on the use of local microorganisms as liquid organic fertilizer. Thirty-five participants attended the implementation of the activity. This activity continued with discussions and questions and answers during the training. The results of this Community Service show that the service method in the form of counseling, training, and question and answer is very appropriate in motivating the community to remodel household waste.
Kedelai merupakan tanaman potensial yang perlu dikembangkan, karena memiliki peluang pasar yang besar di Sumatera Selatan belum banyak dibudidayakan dan produksinya pun masih rendah. Penelitian ini bertujuan untuk mengetahui dan mendapatkan varietas dan dosis pupuk solid yang berpengaruh terbaik terhadap pertumbuhan dan produksi tanaman kedelai (Glycine max (L) Merrill). Penelitian ini menggunakan metode eksperimen dengan Rancangan Petak Terbagi (Split Plot Design). Faktor yang Pertama (Petak Utama) Varietas Kedelai (V) yaitu V1 = Wilis; V2 = Tanggamus dan V3 = Anjasmoro sedangkan Faktor kedua (Anak Petak) Pupuk Solid (S) yaitu S1 = 15 ton ha-1; S2 = 30 ton ha-1 dan S3 = 45 ton ha-1. Penelitian ini telah dilaksanakan pada lahan petani di Kelurahan Sukajadi, Kecamatan Talang Kelapa Banyuasin, pada bulan September sampai Desember 2020. Hasil analisis keragaman (Anova) bahwa perlakuan varietas dan pupuk solid maupun interaksinya berpengaruh nyata sampai sangat nyata terhadap semua peubah yang diamati. Varietas Anjasmoro memberikan hasil terbaik pertumbuhan tanaman kedelai dengan tinggi tanaman tertinggi (64,32 cm), jumlah cabang produktif terbanyak (9,67 cabang), sedangkan varietas Wilis memberikan hasil terbaik produksi tanaman kedelai dengan berat biji per tanaman terbaik (84,11 g), berat biji per petak terbaik (683,67 g), pupuk solid dengan dosis 30 ton ha-1 memberikan hasil terbaik terhadap pertumbuhan dan produksi tanaman kedelai. Interaksi antara varietas Wilis dan pupuk solid dosis 30 ton ha-1 memberikan hasil terbaik terhadap produksi tanaman kedelai sebesar 783,00 g/petak atau setara dengan 2,08 ton ha-1.
Lahan kering memiliki produktivitas tanah yang rendah (pH dan kandungan unsur hara yang rendah), namun berpotensi dalam meningkatkan pertumbuhan dan produksi jagung manis, diantaranya dengan pemberian pupuk organik cair (POC) asal limbah buahan dan anorganik. Diharapkan POC dapat menyumbangkan unsur hara dan dapat mengefisienkan pupuk NPK pada tanaman jagung manis. Penelitian ini bertujuan untuk menentukan konsentrasi POC asal limbah buahan yang tepat dalam mengefisienkan pupuk NPK serta meningkatkan produksi jagung manis. Penelitian lapangan ini dilakukan di lahan milik petani yang terletak di jalan Sukarela, Kelurahan Kebun Bunga, Kecamatan Sukarami, Km 7 Palembang Sumatera Selatan dari bulan Oktober 2019 sampai Januari 2000. Tata letak di lapangan menggunakan Rancangan Petak Terpisah dengan 12 kombinasi yang diulang 3 kali. Sebagai petak utama: POC asal limbah buahan: tanpa, 10, 20 dan 30 mL.L-1 air. Sebagai anak petak: Pupuk NPK: 100, 300 dan 500 kg.ha-1. Produksi terbaik dicapai pada penggunaan POC asal limbah buahan 20 mL.L-1 air dan pupuk NPK 300 kg.ha-1, yang meningkatkan hasil 36,23% bila dibandingkan tanpa POC dan pupuk NPK 100 kg.ha-1 dan mengefisienkan pupuk NPK sebesar 200%.
This study aims to determine and determine the dose of NPK fertilizer with the appropriate application of guano fertilizer on the yield of peanuts (Arachishypogaea L.), The study was conducted from September to December 2020, this study used a split plot design with 3 replicates for a total of 27 plots. The treatment variables were NPK fertilizer (N), namely N1 = 25 kg ha-1; N2 = 50 kg ha-1 ; N3 = 75 kg ha-1 and Guano Fertilizer (G) ie G1 = 5 tons ha-1; G2 = 10 tons ha-1 ; G3 = 15 tonnes ha-1. Observational variables in this study included the number of pods per plant (pods), pod weight per plant (g), weight of 100 seeds (g) and weight of pods per plot (kg). The results showed that combination of NPK fertilizer 75 kg ha-1 with guano fertilizer 10 tons ha-1 gave the highest yield of peanuts at 1.49 kg per plot (2.98 tons ha-1).
