Abstract

Inoculation of beneficial microbes is a way to improve the population of rhizobacteria that has a role in nutrient cycle and hence reduce the level of chemical fertilizer. A pot  experiment was performed to evaluate the effect of and consortia biofertilizer combined with various dose of NPK compound fertilizer on the population of nitrogen-fixing Azotobacter sp. and phosphate solubilizing Pseudomonas sp. in rhizosphere and yield of choy sum (Brassica juncea L.). The experimental was setup in completely randomized block design consisted of ten combinations of various biofertilizer and inorganic fertilizer dose; and three replications. The results showed that Biofertilizer inoculation with or without chemical fertilizer did not improve the population of Azotobacter and Pseudomonas in the rhizosphere but increase the shoot weight of choy sum. Higher shoot weight was showed by crops with ¾ dose of NPK combined with recommended or reduced dose of fertilizer; and recommended dose of NPK and biofertilizer. This experiment verified that the used of consortia biofertilizer composed of Nitrogen-fixing bacteria and phosphate-solubilizing microbes reduced 50-75% dose of NPK.

Abstract

Desa Sindangsari merupakan salah satu wilayah Daerah Aliran Sungai (DAS) Citarum Hulu yang memiliki permasalahan buruknya pasokan air pada musim kemarau. Kondisi ini berdampak pada pertumbuhan ubi jalar, salah satu tanaman utama daerah tersebut. Petani selalu menggunakan teknik pasokan air secara tradisional yang menghabiskan lebih banyak tenaga dan biaya. Para petani seringkali tidak dapat memenuhi kebutuhan air tersebut karena keterbatasan anggaran sehingga menurunkan hasil dan produktivitas ubi jalar. Hasil peninjauan awal menunjukkan bahwa tingkat kekeringan meningkat dari tahun 2019 hingga 2020, begitu pula dengan hilangnya air pada sistem irigasi. Untuk mengatasi masalah ini, program Pengabdian Kepada Masyarakat (PPM) dilaksanakan melalui pembuatan kompos dan biopori untuk konservasi air dan tanah. Program PPM dilakukan dengan seminar dan lokakarya pengomposan dan pembuatan biopori serta pelatihan untuk petani ubi jalar. Petani diajarkan cara membuat kompos dari limbah tanaman ubi jalar dan cara membuat biopori di lahan mereka. Program PPM ini diharapkan dapat mengatasi masalah kekeringan lahan dengan meningkatkan kesuburan tanah dan ketersediaan air melalui kompos dan biopori.

Abstract

Consortium biofertilizer containing Nitrogen (N) Fixing Bacteria and Phosphate (P) Solubilizing Bacteria may substitute inorganic fertilizer in vegetable production. A greenhouse experiment was conducted to evaluate the effect of some combinations and doses of consortium biofertilizer and NPK compound fertilizer on available N and P in the soil, fresh weight of caysim (Brassica chinensis L. var. parachinensis.), and their uptake by caisim shoots after grown in low fertility soil. The experimental design was a randomized block design consisting of seven combinations and doses of consortium biofertilizer and compound fertilizer; and three control treatments. All treatments were repeated three times. The results showed that the combination of the which combination treatment of inorganic fertilizer and biofertilizer had a significant effect on the fresh weight of caysim shoots, available P and N and P uptake after harvesting compared to the biofertilizer treatment alone or without fertilization. Several treatments of combined doses of biofertilizers and NPK compound fertilizer produced the same yield as NPK compound fertilizer alone. The application of 300 kg/ha of compound fertilizer combined with 3,75 L/ha of biofertilizer enabled to increase the yield up to 16% compared to NPK fertilizer alone. This experiment explained that inoculation of biofertilizers can reduce the dose of NPK fertilizer to maintain yield, available P residue in soil and P uptake

Abstract

DOI:10.17014/ijog.9.2.159-172Ultic is the soil characteristics in soil taxonomy when argillic or kandic horizon is found within the depth of 125 cm with the base saturation of less than 35 % on the overall of upper 50 cm. The purpose of this research is to investigate whether ultic horizon was found in the soil developing from the Pleistocene eruption of Mount Tilu (basaltic parent materials), in West Java, Indonesia. The method used was descriptive and comparative surveys of three profiles in the area around Mount Tilu, including the investigation of andic soil properties and the formation of argillic or kandic horizon. The result showed that the soils fulfilled the requirements of andic soil properties to be classified as Andisols. Soil never dried for ninety days cumulative (udic) to be classified as Udands. There were Fulvudands and Hapludands in this location. Accumulation of clays was more than 1.2% higher than the overlying horizon found at the depth of 90, 79, and 51 cm in those three profiles. Base saturation in upper 50 cm ranged from 1.07 to 6.86 cmol kg-1 or less than 35 %, making the soils were classified as Ultic Fulvudands and Ultic Hapludands. The high rainfall in the tropics and Pleistocene age led to the leaching of clays for a long period to form the argillic horizon. The influence of rain was stronger than the basaltic parent materials in forming Ultic Hapludands. Basaltic parent material was not strong enough to produce base saturation of more than 35 %.

Abstract

Kopi Arabika Puntang menjadi salah satu produk unggulan pertanian di Desa Campakamulya, Kabupaten Bandung, Jawa Barat. Cita rasa dan aroma yang khas menjadikan kopi ini banyak peminat, namun produktivitas kopi arabika ini terus menurun. Pengabdian pada masyarakat (PPM) ini berupaya mendongkrak produksi kopi Arabika Puntang di Lembaga Masyarakat Desa Hutan (LMDH) Bukit Amanah di Desa Campakamulya, Kabupaten Bandung, Jawa Barat. Produktivitas kopi yang rendah di wilayah ini disebabkan oleh kondisi fisik lingkungan dan tanah yang kurang baik. Selain itu, setidaknya terdapat 17 spesies nematoda parasit yang berbeda ditemukan di tanah perkebunan kopi dengan tegakkan hutan pinus, yang dapat menyebabkan pertumbuhan terhambat, pematangan buah tidak merata, dan hasil panen rendah. Untuk mengatasi masalah tersebut, PPM ini mengusulkan beberapa solusi yaitu perbaikan kesuburan tanah melalui pemupukan berimbang, pengendalian hama dan penyakit, dan praktik konservasi tanah. Seminar dan lokakarya dengan tema "Peningkatan Produktivitas Lahan Perkebunan Kopi Berbasis Karakteristik Tanah dan Lingkungan" juga menjadi bagian dari program PPM ini. Penerapan metode ini diharapkan mampu meningkatkan produksi kopi Arabika Puntang dan membantu memenuhi permintaan dunia akan kopi berkualitas tinggi ini. Petani juga mendapat manfaat dari program ini, karena meningkatkan pemahaman mereka tentang tingkat kesuburan tanah dan cara menjaga kesuburan tanah.

Abstract

Lithologic discontinuity reflects the distinct change between different types of soil layers that can occur due to various geological process, resulted in variation composition, colour, texture, organic matter, consistency, structure, and others characteristics. Soils derived from volcanic eruption have the possibility to have lithologic discontinuity in the depth of the soil profiles due to the different eruption that formed the soils. Soils developed from the eruption of Mt. Patuha were investigated whether lithologic discontinuity presence the soil layers. The research used descriptive and comparative method of two profiles, analysed the soil macro-morphology and soil laboratory analyses covered colour, organic carbon, texture, consistency and structure. The result showed that the unusual pattern distributed of colour, organic matter, consistency, structure indicated the lithologic discontinuities of the underlying 2Ab (A buried) horizon to the overlying horizon. The darker colour, higher organic matter content, friable consistency in 2Ab in deeper depth, were some indications of lithologic discontinuities, where in soil without lithologic discontinuities the deeper depth or horizon was normally lighter colour, lower organic matter content and firmer consistency. However, detailed analysed with instruments like XRF and VIS DRS are needed to have the precise elemental composition in every horizon which conclude the horizon from the same or different parent materials.

Abstract

Land use conversion can affect characteristics of soil and also soil quality. The present study evaluate theimpact of land use conversion from pine forest to bush in tropical volcanic soils in Indonesia. We comparedtwo soil profiles from the same areas (uphill slope of Mt. Tangkuban Perahu) and analysed theirmorphological, physical, and chemical soil properties. Our study showed that there was a decrease in soilorganic carbon stock about 3.7% (382 ton C ha-1) after approximately 8-15 years of land conversion. Other physical and chemical soil properties, such as soil texture, bulk density, pH, exchangeable base and acidity,cation exchange capacity, and base saturation were relatively similar. This research provide insight intohow change in vegetation cover can affect carbon and nutrient dynamics as well as become a baseline tounderstand soil recovery potential if the land is restored to forest or bush in volcanic soils.
