Increased productivity of maize can be done with the use of high quality seeds from improved varieties such as hybrid seed. The objectives of this study were Increasing productivity of maize female parent is important in order to reduce the price of hybrid seed. The objectives of this study were to determine the nitrogen fixing bacteria compatible with phosphate solubilizing bacteria (PSB), and using those bacteria to increase physiological seed quality and seedling growth of maize female parent. The research consisted of laboratory and field experiments. Laboratory experiment for the isolation and identification of rhizobacteria resulted in 25 Azotobacter and 29 Actinomycetes non-pathogenic isolates capable of fixing nitrogen and PSB selected for compatibility tests were AB3, B28, P12, P14, P24, and P31. The compatibility test showed 25 pairs of BPF with Azotobacter and 16 pairs of BPF with Actinomycetes were mutually compatible. The BPF pair with Azotobacter or Actinomycetes P24-AzL7, P24-AzL9, B28-AcCKB4, P24-AcCKB9, P24-AcCKB20, and P24-AcCKW5 were able to increase the vigor index of hybrid maize female parent seed. Field experiment was arranged in a split plot design with three replications. The main plot was dosage of N-P fertilizer (0%, 25%, 50%, 75%, and 100% of recommendation dosage), and the subplot was 12 rhizobacteria treatments selected from 25 compatible pairs of BPF with Azotobacter and 16 pairs of BPF with Actinomycetes and 1 control. The application of compatible pairs of bacteria had a significant effect on plant height, the number of leaves at 3 and 4 weeks after planting and plant dry weight. However, the best treatment i.e. B28-AcCKB4 was not significantly different with the nutrient broth treatment (as control).<br /><br /><br />
ABSTRAKPada era globalisasi persoalan mengenai pencemaran dan kerusakan lingkungan menjadi suatu permasalahan yang masih belum bisa dipecahkan oleh masyarakat secara berkelanjutan. Salah satu penyebabnya adalah penumpukan limbah seperti limbah pertanian. Tujuan kegiatan pengabdian ini adalah untuk mengolah limbah pertanian menjadi produk asap cair yang multifungsi dengan menggunakan metode pirolisis.Kegiatan pengabdian dilaksanakan mulai bulan Agustus sampai dengan Desember 2017 di Desa Sukorejo Kecamatan Parengan Kabupaten Tuban dengan kelompok sasaran adalah petani. Metode kegiatan ini meliputi a) penyuluhan dengan tujuan meningkatkan pemahaman petani dalam mengelola limbah pertanian menjadi asap cair, b) Difusi Iptek melalui pembuatan peralatan asap cair dengan menggunakan metode pirolisis, c) Pelatihan dan pendampingan dalam proses pembuatan asap cair berbahan limbah pertanian disertai dengan monitoring dan evaluasi. Hasil dari kegiatan adalah meningkatkan pengetahuan dan ketrampilan mitra, terciptanya instalansi alat pembuatan asap cair dan asap cair berbahan limbah pertanian yang multifungsi. ABSTRACTIn the era of globalization the issue of pollution and environmental damage becomes a problem that still can not be solved by society in a sustainable manner. One reason is the accumulation of waste such as agricultural waste. The purpose of this activity is to treat agricultural waste into a multifunctional liquid smoke product using pyrolysis method.The activity was carried out from August to December 2017 in Sukorejo Village, Parengan District, Tuban Regency with the target group is farmers. The methods of this activity include a) counseling with the aim of improving the understanding of farmers in managing agricultural waste into liquid smoke, b) Making liquid smoke equipment using pyrolysis method, c) Training and assistance in the process of making liquid smoke made from agricultural waste accompanied by monitoring and evaluation. The result of this activity is to improve the knowledge and skills of partners, the creation of liquid smoke making equipment by pyrolysis method and liquid smoke made from agricultural waste that is multifunctional in agricultural cultivation and publication using mass media.
Shallot seed production using true shallot seed (TSS) is more effective and efficient in terms of storage and distribution, but it must be sown first. The purpose of this study was to determine response and obtain the best combination of number and age of TSS seedlings in increasing shallot seeds production. The experiment was arranged in a randomized complete design of number × age of seedling with 3 replications. The number of seedlings consisted of 1, 2, 3, and 4 seedlings for each planting hole, and the age of seedlings consisted of 25, 35, 45, and 55 days after seeding (DAS). The result showed the number and age of TSS seedlings affected vegetative growth parameters (plant height and the number of leaves), yield (yield per m 2 , dry yield per m 2 , sample yield, sample dry yield), productivity, and characteristics of the seed bulbs produced (number, diameter, and weight). The treatment of 3 seedlings per planting hole and 35 DAS significantly and consistently showed better response than other treatments. That treatment increased vegetative growth parameters (plant height and the number of leaves), yield (yield per m 2 , dry yield per m 2 , sample yield, sample dry yield), productivity, and the number of bulbs with lighter weight and smaller diameter characteristics of bulbs.
Kajian ini bertujuan untuk mengetahui faktor internal dan eksternal yang dihadapi petani dalam menumbuhkan penangkar benih padi bersertifikat, serta merumuskan alternatif strategi dan prioritas strategi yang dapat direkomendasikan untuk petani di Desa Mulyodadi. Kajian dilaksanakan pada bulan Februari-Juni 2020 di Desa Mulyodadi, Kecamatan Bambanglipuro, Kabupaten Bantul, Daerah Istimewa Yogyakarta. Metode yang digunakan dalam kajian ini yaitu metode kombinasi. Penentuan sampel petani dilakukan dengan proportional random sampling. Hasil dari kajian yaitu analisis faktor internal dan eksternal yang kemudian diidentifikasi dengan matriks IFE dan EFE. Data dari matriks IFE dan EFE digunakan untuk dasar penyusunan alternatif strategi dengan analisis matriks IE dan SWOT, sehingga didapatkan 8 alternatif strategi. Tahapan untuk menentukan prioritas strategi yang dapat direkomendasikan menggunakan analisis QSPM. Hasil dari prioritas strategi yaitu menumbuhkan penangkar benih padi bersertifikat secara berkelompok dengan melakukan penyuluhan SOP perbenihan. Selanjutnya dilakukan penyuluhan tentang penumbuhan penangkar benih padi bersertifikat secara berkelompok. Hasil penyuluhan menunjukkan bahwa aspek pengetahuan dan sikap mengalami peningkatan sebesar 45,5% dan 31,2%.
Invigorasi merupakan salah satu metode yang digunakan untuk mengatasi benih yang telah mengalami deteriorasi. Osmoconditioning adalah teknik invigorasi dengan perlakuan hidrasi benih terkontrol dengan tujuan mempercepat proses imbibisi dan aktivasi enzim sehingga perkecambahan terjadi lebih cepat dan serempak. Penelitian ini bertujuan untuk mengetahui teknik osmoconditioning yang mampu meningkatkan mutu fisiologis benih terung yang telah lewat masa edar/kadaluarsa. Penelitian ini dilaksanakan secara acak lengkap faktor tunggal yaitu perlakuan osmoconditioning yang terdiri dari 9 (sembilan) perlakuan yaitu kontrol, air hangat, ekstrak bawang merah, Poli Etilen Glikol (PEG) 1%, PEG 3%, PEG 5%, KNO3 2 gr/L, KNO3 4 gr/L, dan KNO3 6 gr/L. Masing-masing perlakuan terdiri dari 25 butir benih dan diulang 3 kali. Benih terung kadaluarsa 2 tahun 10 bulan telah mengalami deteriorasi dengan viabilitas <80%. Perlakuan osmoconditioning menggunakan KNO3 mampu meningkatkan viabilitas maupun vigor benih terung kadaluarsa nyata lebih baik dibandingkan kontrol dari pengamatan daya berkecambah, indeks vigor, bobot kering kecambah normal, serta tinggi kecambah. Perlakuan osmoconditioning dengan PEG menghasilkan panjang akar paling besar sebagai respon benih terhadap lambatnya imbibisi yang cenderung mengarah ke kondisi kekeringan.
