Penggunaan Limbah Media Tanam Jamur Tiram pada Budidaya Tanaman Kacang Tanah dan Bawang Merah

Mushroom plant media waste is potentially to be used as organic fertilizer, because the main ingredient of the mushroom plant media is an organic material ie sawdust. It certainly would not only have an impact on reducing of pollution but can also serve as a source of organic matter to the soil. The use of organic fertilizers will be very useful to reduce the occurrence of land degradation both physical, chemical and biological farming practices due to the high external input. Use of mushroom plant media waste on groundnut cultivation can improve significantly the dry weight of pods even though their effectiveness is lower when compared with the use of manure. While the onion cultivation, use of mushroom plant media waste as much as 15 t / ha can give no significantly different effects with the use of manure. Even the use of mushroom plant media waste in the first planting period can reduce the use of urea in the second cropping period of up to 100%. Key word : waste, groundnut, onio

Pengaruh Kombinasi 2,4-d dan Benzil Amino Purin (Bap) terhadap Pembentukan Kalus pada Eksplan Daun Kencur (Kaemferia Galangal L) secara In Vitro

This research aim to learn the influence of combination of concentration plant growth regulator 2,4-D and BAP to callus induction at eksplan of Koempheria galanga leaf, proliferasi callus at eksplan and also know the interaction influence between 2,4-D and BAP to obtaining culture of callus Koempheria galanga which its growth good. This research was conducted from April to September 2010, in Laboratory of Tissue Culture, FKIP, University of Muhammadiyah Purwokerto. The Trial was arranged in Complete Random Design (CRD). Perception variable cover the : time induce the callus, percentage explant growth, callus volume which grow from explants leaf , culture appearance visually and percentage contamination. Result of research indicate that the Combination of concentration of Plant growth regulator 2,4-D at concentration 0 - 2 mg / l of medium and BAP at] concentration 0 - 0,3 mg / l medium still not yet able to induce formed is callus at eksplan of leaf Koempheria galanga during research. Disability Explants form the callus because of fenol high rate enough in tissue explant and also not yet proportional it concentration 2,4 D and Benzil Aminopurin which can depress the sintesis fenol in and death at explant of koempheria galanga leaf

Keragaan Organ Source Dua Varietas Bayam Cabut pada Variasi Media Tanam Arang Sekam

This study aims to determine the source organ performance of two spinach varieties in some planting media variation of charcoal husk. Research conducted at the Green House of Agricultural Faculty of Muhammadiyah University for four months starting in May-August 2012. The research was arrangged by Randomized Completely Block Design and each treatment was repeated three times. The study consisted of two factors: First, the varieties of spinach (V), consists of two varieties of the Maestro (V1) and Bisi (V2). Second, the addition of charcoal husk (A), consisting of A0 (without a charcoal husk / soil media only), A1 (given the husk charcoal at 25%), A2 (husk charcoal as much as 50%) and A3 (husk charcoal in 75%). The results showed that there was no difference between the source organ performance Maestro spinach varieties with varieties Bisi, husk charcoal dose needs to be added to spinach plants have best performance of source organs is 25% media volume, although this is not significantly different with only soil media and there was no significant interaction between type of spinach with a dose of charcoal husk of source organ performance of Maestro and Bisi spinach varieties

Kajian Pengembangan Bawang Merah pada Lahan Berkadar Liat Tinggi (Vertisol) dengan Penambahan Pupuk Organik

The aim of this research was to study of onion development at land with high clay content by organic fertilizer aplication. The research was conducted in Dukuhwaluh village, Kembarang Sub-District, Banyumas District on February until September 2006. The research was arranged by Randomized Completely Block Design with four replications. The first factor of treatment was kind of soil (T) consist of Alfisol dan Vertisol soil; the second factor was dosage of organic fertilizer (P) consist of four levels i.e. P0 = without organic fertilizer , P1 = aplicated 5 tons /hectare organic fertilizer, P2 = aplicated 10 tons/hectare organic fertilizer and P3 = aplicated 15 tons/hectare organic fertilizer. Results of the study showed that there are possibility of using of vertisol soil by organic fertilizer aplication for onion development location. The dosage of organic fertilizer that can to support onion development was 15 tons/hectare minimal. Using of Alfisol soil with 15 tons/hectare organic fertilizer aplicated can give higher of yield than the treatment other
