Abstract

Increasing P availaibility can be done using Phosphate solubilizing microorganism, but available information about indigenous phosphate solubilizing microorganism utilization from paddy soil that intensively fertilized with P is limited. The objectives of this experiment were to isolate, to select and to test the potential  of phosphate solubilizing fungi (PSF) in  increasing P availability, P uptake and rice production. Five isolates of PSF, referred to A1, A2, A3, A4 and A5 isolates, were belong to the Aspergillus genera. Field experiment was arranged in a randomized block design with one factor and 3 replications. The treatments consisted of 11 combinations of PSF and NPK fertilizer, i.e., without PSF + 100% rate of NPK fertilizer; PSF A1 + 50% rate of NPK fertilizer; PSF A1 + 100% rate of NPK fertilizer; PSF A2 + 50% rate of NPK fertilizer; PSF A2 + 100% rate of NPK fertilizer; PSF A3 + 50% rate of NPK fertilizer; PSF A3 + 100% rate of NPK fertilizer; PSF A4 + 50% rate of NPK fertilizer; PSF A4 + 100% rate of NPK fertilizer; PSF A5 + 50% rate of NPK fertilizer; PSF A5 + 100% rate of NPK fertilizer. Experiment results showed that application of  PSF isolates increased P availaibility, P uptake, rice growth and rice production significantly. Application of PSF A1 + 50% rate of NPK fertilizer was  the best treatment as indicated by the increased in weight of 1,000 rice grains, P availaibility and P uptake

Abstract

Paddy sawah cultivation that done for long time used chemical fertilizer with dosage that continously increased  but many reports indicated no  respond on increasing paddy production. Utilization of chemical fertilizer caused decreased soil quality, which  fertilizer respond  was less that indicated  by  production that hard to increase while  fertilizer dosage  was  increased every year so farm cost more expensive especially for buy fertilizer. This problem must be solved by applicated res earch result for farmer with utilized harvest waste as organic fertilizer by composting. This IbM activity aim was to used  harvest waste as organic fertilizer by composting to decrease fertilizer cost and  farmer income be increased. This activity target was found IPTEKS for farmer how processes to made harvest waste be organic fertilizer by composting to increased fertilizer efficiency so  that chemical fertilizer can decreased. This activity result after socialized about utilization and  composting processes was farmer understood and could made compost from harvest waste and  increased  farmer knowledge abaout utilization harvest waste as organic fertilizer.Key words: compost, farmer, harvest waste

Abstract

Phosphate solubilizing fungi (PSF) from paddy soil can used as biofertilizer to increase P availability.Aimed this experime nt was to increase P availability, growth and paddy rice production. The randomly complete block design used that consist two factors, eg. Dosage of PSF (A) and anorganic P fertilizer (F). Factor dosage of PSF (A) with four levels: without PSF; 2 kg PSF/plot; 4 kg PSF/plot and 6 kg PSF/plot. Factor anorganic P fertilizer with three levels: without anorganic P fertilizer; 50% anorganic P fertilizer and 100% anorganic P fertilizer. Experiment result showed that application of PSF increased P availaibility, growth and plant production more high than without application of PSF. Application of anorganic P fertilizer increased P availability, growth and plant production more high than without application of anorganic P fertilizer. Interaction between  application of PSF with anorganic P fertilizer (4 kg PSF/plot + 100%  anorganic P fertilizer)  increased P availibility, growth and plant production more high  than without  application of  PSF and anorganic P fertilizer (control).

Abstract

The research was conducted to evaluate the performance of tomatoes varieties on growth, yield and quality through the application of partial rootzone drying. The study was conducted in green house at the Faculty of Agriculture Universitas Islam Sumatera Utara (UISU) Medan in May 2014 until September 2014. The planting media used were straw compost mixed with top soil enriched withUrea, SP ─ 36 and KCL fertilizer filled into polybeg up to 10 kg in weight. Observation variables are: the growing, yield  and quality of tomato

Abstract

Kegiatan penerjemahan tidak persis diketahui kapan dimulai, namun pastilah penerjemahan lahir setelah penulisan berkembang. Di abad ke-20 teori penerjemahan mengalami perkembangan pesat dan menjadi salah satu bidang ilmu. Percepatan globalisasi dengan penggunaan teknologi internet dewasa ini, penerjemahan dan terjemahan merupakan kegiatan dan produk yang sangat penting bagi siapa saja yang ingin mengenal maupun memperkenalkan hal-hal yang dimiliki oleh suatu kelompok, budaya, atau bangsa kepada yang lain. Pembelajaran menerjemahkan sebenarnya sudah dimulai dari fase awal pembelajaran bahasa asing, mamun kemampuan menerjemahkan tidak serta-merta diperoleh dengan menguasai bahasa asing. Mengingat bidang penerjemahan merupakan ladang yang terbuka luas bagi profesi penerjemah, maka generasi muda, terutama mahasiswa jurusan penerjemahan perlu dimotivasi untuk menggiati bidang penerjemahan yang bermanfaat untuk menunjang pencapaian mereka dalam akademik maupun karir dan kehidupan profesional mereka di masa yang akan datang.
