Abstract

Multiplication of multiantagonist Trichoderma sp. and Streptomyces sp. done on agar plates and liquid media covered for multiplication and facilitate cell harvesting. Root suspension containing microorganisms and humic liquid is a biopesticide and fertilizer material that was expected to be more effective for biodegradation of biological agents to have more value. This study aims to determine the ability of life and propagation Trichoderma sp. and Streptomyces sp. in root suspension, humic liquid and sugar potato extract. This study used a descriptive observations on days 10th, 14th and 17th before inoculation of Trichoderma sp. and Streptomyces sp showed that in liquid humic medium there are microorganisms but fewer number of microorganisms on root suspension media. The 17th day after inoculation of the Trichoderma sp. and Streptomyces sp showed that in the humic liquid medium, the biological agent did not grow, while the root suspension medium was only Streptomyces growing but not as much as developed on sugar potato extract.

Abstract

The increasing population and the problem of land use change that continues to increase raises the problem of food security. Government programs have been carried out such as the expansion of marginal land in coastal areas, namely saline land. The research objective was to assess the effectiveness of P uptake due to the aplication of humic acid and silica on lowland rice crop production. The research method was arranged in a randomized block design that was repeated 3 times. Size of planting 2x2 m2, 4 kinds of treatment include; a. control b. humic acid c. silica d. humic acid + silica. The results showed that the application of humic acid + silica had a significant affect the rice growth with an average plant height of 85,74 cm at 10 mst and rice production of 4,20 ton.ha-1. Humic acid + silica can also improve soil chemical properties : pH 6,95 CEC 40,24 and P nutrient 197,6. This is because the ability of humic acid to chelate by removing the Pbonds from the uptake of metal and silica elements can increase the P content in the soil into a from that is more available to plants.

Abstract

The mineralization process is responsible for the availability of N in the soil. The purpose of this study is to examine the management of coffee land (Coffea L.) and climate on the rate of soil Nitrogen mineralization. In situ incubation research by implanting 15.5 cm long cylindrical pvc ring; diameter of 14 cm that has been perforated around it and a wire covering / net so that animals such as scorpions and snakes do not enter the hole. The research was arranged in factorial randomized block design which was repeated 3 times. Factor 1 : 3 types of land management and factor 2 : 4 types of organic matter. The level of N mineralization is evaluated against the levels of N-nitrate and N-ammonium soil. The highest NH4+ N concentration of 0.060% was found in the L1S3 treatment (first land, mixed ring) and the lowest NH4+ concentration in the L3S1 treatment (third land, control ring) 0.03%. NO3 concentration - interaction occurs with the highest NO3 concentration in the L2S3 treatment (second land, mixed ring) 0.092% and lowest NO3 concentration in the L1S1 treatment (first land, control ring) 0.013% with a BNT value of 5% at 0.023%. So the fastest nitrogen mineralization occurs in soils that get litter of shade plants (mixed / S3). The value of mineralization rate is strongly influenced by temperature, the increase in the value of mineralization rate due to temperature is due to the faster process of decomposition of organic matter.

Abstract

Porang merupakan tanaman yang potensial untuk dikembangkan sebagai komoditi ekspor sebagai bahan makanan maupun bahan industri. Umbi porang mempunyai potensi yang sangat besar dalam bidang produksi, namun hal ini belum dikelola secara optimal. Penelitian ini bertujuan untuk mengkaji tingkat kesesuaian lahan di Kecamatan Wonosalam Kabupaten Jombang untuk pengembangan tanaman porang. Penelitian ini menggunakan metode survey yang dilaksanakan dengan teknik pengambilan dan analisa sampel tanah terpilih. Pengambilan sampel dilakukan berdasarkan overlay atau tumpang tindih peta penggunaan lahan, geologi, topografi, dan kelerengan di Kecamatan Wonosalam. Hasil Overlay diperoleh 11 SPL (Satuan Peta Lahan) yang memenuhi karakteristik tiap peta. Hasil penelitian menunjukkan bahwa lahan di wilayah penelitian memiliki kemiringan bervariatif paling rendah 11,3% dan paling tinggi 35%. Tekstur tanah di dominasi oleh tekstur halus dengan nilai tertinggi 62,13% liat pada LD3. Nilai pH masam (4,71 – 5,56). C-organik bervariasi sebesar 0,17 – 3,63%. Nilai KTK di wilayah penelitian yakni 17,99-33,15 Cmol/kg (+). LD1, LD3, KB1, KB2, KB3, KB4, HT1 mempunyai kelas lahan cukup sesuai untuk pengembangan tanaman porang dengan faktor pembatas curah hujan dan kemiringan lereng (S2 wa, e). LD2 mempunyai kelas lahan cukup sesuai dengan faktor pembatas curah hujan (S2 wa). HT2, HT3, HT4 tidak sesuai untuk pengembangan tanaman porang dengan faktor pembatas kemiringan lereng (S3 e). Faktor pembatas didominasi oleh Curah Hujan dan kemiringan lereng pada setiap SPL.
