Abstract

Sebagian besar sumber daya lahan di Indonesia merupakan lahan kering yang memiliki potensi untuk usaha pertanian. Pada umumnya kawasan lahan kering tersebut memiliki topografi dari landai sampai terjal, sehingga apabila dimanfaatkan untuk usahatani sangat rentan terhadap erosi. Tingkat erosi yang tinggi merupakan masalah serius terhadap kelestarian sumberdaya lahan di Daerah Aliran Sungai (DAS) dibagian hulu, dan menimbulkan pengaruh negatif di DAS bagian hilir.Usahatani pada lahan kering menghadapi problema yang sangat kompleks,beragam dan beresiko tinggi, oleh karena itu diperlukan penelitian dengan strategi pendekatan pengelolaan secara terpadu. Penelitian dan pengembangannya melibatkan berbagai disimplin ilmu (interdisipliner). institusi (interinstitusi) dan petani sebagai pengelola utamanya.Pengembangan sistem usaha tani konservasi terpadu pada sub DAS Prambanan hulu dengan tujuan mencari solusi pengembangan teknologi alternatif serta upaya mengendalikan erosi, ternyata telah mendapat respon positif baik oleh petani binaan maupun non-binaan.

Abstract

As one of the state with the longest and widest coastal region in the wo, Indonesia can exploit various existing coastal resources. The agriculture term of coast outside of tide and ebb region was not many recognized, however at the last some years the coast agriculture cultivation have rapid developed not only the tide and ebb farming, but sea grass cultivation and horticulture crop and also another vegetable crop. Therefore the thing that need to get attention is possibility the presence of ground water contamination and sea water intrusion as effect of usage the manure and poisonous pesticide and ground water intake which exceeding the support power. From the result of environmental monitoring, it apparent the ground water quality in the Glagah’s coastal area was still good enough because under quality standard for drinking water, but the thing which need to get attention was the high collie bacterium content due to the usage of immature cage manure.

Abstract

Usahatani pada lahan berpasir akan dijumpai banyak kendala yang berhubungan dengan kondisi fisik tanah, hidrologi tanah dan iklim, lebih khusus lagi kondisi iklim mikro yang kadang kurang kondusif untuk pertumbuhan tanaman. Oleh karena itu perlu adanya terobosan guna melakukan rekayasa lingkungan, agar supaya keadaan yang kurang menguntungan tersebut dapat dimanfaatkan secara optimal oleh petani, yaitu melalui masukan teknologi alternatif berupa penambahan bahan pengkondisi tanah (pupuk kompos, pupuk kandang, biomikro), pembuatan jaringan irigasi dan pembuatan pelindung/naungan yang pada hakekatnya berfungsi untuk mengurangi fluktuasi suhu harian pada tanah (intensitas matahari), penurunanpenguapan dan kehilangan air (evaporasi).

Abstract

During the present time, the coastal area is lack of interested by the farmer as the cultivation site of agriculture plant. It is caused by the problem constraint of land physical character and the climate (particularly, micro climate), so that most confined the kinds of plant may be cultivated. The more narrowed of agriculture area, then optimalizing the use of coastal area for developing agriculture is necessary to conduct, although must throungh various means with an environment reengineering, as climate modification, conservation efforts of land moisture, supplying irrigation water, and etc.So that in the research will be implemented the research on the melon plant cultivation with various treatment.But, these condition of micro climate can be manipulated or reengineered with using simple technology in shape of closed shade, so that can be created an ideal condition for cultivation requirements. The result show that melon plant cultivated under the shade with sprinkler irrigation and drip irrigation gives the highest result that is 325 kg/70 m2 or 4,65 kg/m2, the melon planted under the shade + sprinkler irrigation + mulse the result 272 kg/70 m2 or 3,89 kg/m2, while the lowest result is that planted without using the shade with sprinkler irrigation and drip irrigation : 200 kg/m2 or 2,86 kg/m2.

Abstract

Di Indonesia, tanah-tanah marginal dengan kandungan pasir tinggi ( tanah vulkan berpasir kasar dan tanah berpasir digumuk-gumuk pantai), merupakan contoh dari banyak tanah bermasalah. Oleh karena itu upaya untuk mengatasi tanah bermasah tersebut perlu dilakukan. Budidaya pertanian pada tanah pasiran akan dijumpai banyak kendala yang berkaitan dengan sifat fisik, kimia dan hidrologi tanah serta iklim yang kurang kondusif bagi pertumbuhan tanaman, lebih khusus lagi tanah tersebut mempunyai sifat mudah meloloskan air, kandungan bahan organik rendah serta suhu tanah yang tinggi, sehingga kurang sesuai untuk pertumbuhan tanaman. Dengan menambah bahan pengkondisi tanah maka telah dapat merubah sifat fisik dan kimia tanah. Perubahan fisik tanah tersebut mengarah pada berat volume tanah yang meningkat, porositas tanah menurun,permeabilitas tanah menurun dan kadar lengas tanah meningkat. Keberadaan mikroba didalam tanah memegang peranan penting dalam transpormasi yang menyebabkan perubahan dalam sifat fisik dan kimia tanah.

Abstract

Absorption of heavy metals by plants is influenced by soil and plant biology. Heavy metals are absorbed into plant tissues through the root, then enter the food chain cycle. Metal will accumulate in body tissues and can have negative impacts for humans, animals, and plants when exceeding the limit of tolerance. Heavy metal accumulation in plant tissues can directly affect plant growth and production, can indirectly affect human health when consuming food contaminated heavy metals. The research objective was to determine the ability of biological fertilizers containing bacteria Azotobacter sp. and Pseudomonas sp., in absorbing heavy metals (Cu and Pb) contained in landfill waste compost, which is used to fertilize crops corn (baby corn). The research methodologyuses a split plot design arranged in Completely Randomized Design with 3 blocks as replicates. The first factor that serves as the main plot of the biological fertilizer, consisting of two cedars, namely: no biological fertilizers and biological fertilizers. The second factor that functions as a sub plot that is a combination of landfill waste compost with NPK fertilizer, consisting of four treatments, namely: Compost waste landfill: no fertilizer NPK = 1: 0; compost waste landfill: NPK = 2/3 : 1/3; compost waste landfill: fertilizer NPK = 1/3: 2/3Without landfill waste compost: NPK = 0: 1. The results showed that administration of biological fertilizers in combination with compost waste landfill is more dominant for increasing and improving soil physical chemistry, such as increasing soil pH, nutrients nitrogen, phosphorus and potassium and cation exchange capacity (KPK). Biological fertilizer containing bacteria Azotobacter sp. and Pseudomonas sp. may reduce the uptake of heavy metals Cu to below the threshold of 2.526 to 15.79 ppm, the maximum content of Cu ranges between 20-100 ppm. The mean content of Pb in tissues and cobs of corn is above the maximum limit of 29.80 to 42.69 ppm, which is still allowed Pb content between 0.1 to 10 ppm. Means baby corn crop is not safe for consumption.key words: compost from the landfill, heavy metals, biological fertilizer

Abstract

Soil erosion is a major factor leading to cause land damage in the upstream region. Therefore, erosion control should be done in the preservation of land resources and the environment can be maintained and the welfare of farmers can be improved. Land Ultisol widespread in many Kalimatan Islands, ultisol soil types other than guilty of fertility, soil types have the property ultisol easy erosion. As a result of coal mining activities carried out by PT KPC lead to peeling layers of top soil to the depth of rock. This stripping has directly changed the soil condition. Ultisol soil physical conditions in Kalimanan (available water capacity, density lumps, texture, structure, pore space and permeability of the soil) are relatively low, so they need to improve theaddition of organic materials, and lime. The process of reclamation of former coal mining PT. KPC has been done very well. The analysis of fertility levels and the amount of potential soil erosion occurs indicates that the post-miningrehabilitation revegetation way to post-mining land with the procedure referred. It can be seen from the parameters of soil fertility and erosion rates of post-mining land have been rehabilitated (56.5614 erosion rates tons/hectare/year) with areas of pristine forests (erosion rates 52.175 tons/hectare/year) were not show significant changes.Keywords: ultisol, rehabilitation, physical soil, erosion
