Abstract Agroforestry systems may play a critical role in reducing the vulnerability of farmers' livelihood to droughts as tree‐based provide several mechanisms that can mitigate impacts from extreme weather events. Here, we use replicated throughfall reduction experiment study drought response cacao/ Gliricidia stand over 13‐month period. Soil water content was successfully reduced down soil depth at least 2.5 m. Contrary our expectations measured only relatively small nonsignificant...
Electrogenic microbes have been exploited in the microbial fuel cell (MFC) system for harvesting bioelectricity. Electrogens are widely distributed various environments, but exploration of this group from ecosystems Indonesia is still limited. This present study aimed to isolate electrogenic bacteria sediments two waterlogged (dam and paddy field) using serial dilution into extinction method prior streak plate on solid thioglycollate media supplemented with Fe3+. Electrochemical evaluation...
<p>One way to control or slow down the nutrient release rate from fertilizer is by coating technique. Nowadays use of biodegradable materials for slow-release (SRF) preferable because environmental issues. This research was aimed make SRF using starches and cellulose as test nutrients. Five kinds (cassava, corn, sago, wheat, glutinous rice) carboxymethyl (CMC) were used material granulated NPK fertilizer. The coated fertilizers (NPK SRF) tested their leaching in soil percolation...
The effectiveness of rock phosphates (RP) on plant growth is often lower than that chemically synthesized fertilizer SP-36. Phosphate solubilizing microbes (PSM) are potentially used to enhance RP dissolution and agronomic for cacao plant. This study was carried out assess the ability several PSM dissolve insoluble phosphate, produce phytohormones, increase in seedling at acid soil. Five phosphate bacteria (PSB) one fungi (PSF) were evaluated their solubilize liquid medium (added Ca3[PO4]2,...
The application of microbial fuel cells is still facing some challenges due to its low power output and high internal resistance. It desirable obtain a stable consistent from an MFC support practical real-world applications. Five electroactive bacteria (isolate LGf1, LGf11, LGf15, LGf20, LGf22) isolated the sediment Waduk Saguling were exploited as potential anodic biocatalyst for MFC, performance these MFCs studied in terms voltage generation (open close circuit), density losses...
Abstract. Sutio G, Iskandar, Indriyati LT, Djajakirana G. 2023. Effectiveness of potassium humate and endophytic bacteria from Serratia marcescens strain NPKC3_2_21 in increasing root weight paddy cultivation acidic soil. Biodiversitas 24: 6316-6322. Phosphorus (P) deficiency is a significant factor limiting rice agricultural production The availability P soil generally insufficient because substantial portion absorbed by Al³? Fe²?, rendering it inaccessible to plants. This hampers proper...
The effects of biochar as soil ameliorants depend on their characteristics that are influenced by the variation in biomass origin and pyrolysis process. In this context, objective study was to determine chemical physical seven derived from different wastes - rice husk, corn cob, empty oil palm fruit bunch, bagasse, sawdust albazia (<em>Albizzia falcataria</em>), maesopsis (<em>Maesopsis eminii</em>), mahogany (<em>Swietenia macrophylla</em>) at two...
Tanah berpasir memiliki kemampuan retensi air, kemantapan agregat, dan kadar unsur hara yang tergolong rendah. Untuk meningkatkan kualitas tanah ini dilakukan upaya pemberian berbagai dosis campuran kompos fly ash-bottom ash (FABA) sebagai amelioran. Tujuan penelitian yaitu menguji pengaruh FABA bahan amelioran pada terhadap karakteristik kimia pertumbuhan tanaman tomat (Solanum lycopersicum). Percobaan pot di Rumah Kaca Cikabayan, IPB University menggunakan Rancangan Acak Lengkap (RAL)...
<em>Using acid soil as a cacao seedling medium limits the growth due to low fertility, thus necessitating ameliorant treatment improve its chemical, physical, and biological quality. This study aimed investigate effect of husks organic fertilizer biochar on chemical properties media growth, was conducted in Soil Biotechnology Laboratory Fertility Laboratory, Bogor Agricultural University Pakuwon Experimental Station at Indonesian Industrial Beverage Crops Research Institute (IIBCRI),...
Collembola is one of the dominant microarthopods in almost all soils types. They have important function food webs soil ecosystem. This research was done at Cikasungka oil palm plantation for six months (April until September 2014). The aim to collect information diversity abundance and population fluctuations Collembola, their linkages between environmental factors. Collembolans were collected based on four points sample from five trees which has similar criteria. Distance 0, 120, 240 cm...
The low-efficiency problem in fertilizer application can be overcome by controlling solubility, i.e. rendering the to released gradually; such material is also known as slow-release (SRF). This research was aimed formulate SRF coating technique using acrylic and chitosan material, evaluate resistance too fast disintegration, rate of nutrient release method. results demonstrated that formulation containing N, P, K, Fe, Cu, Zn with granulation yielded 74% granules 2-5 mm diameter. SRFs...
Abstrak. Memperkirakan konsentrasi karbon organik terlarut (Dissolved Organic Carbon, DOC) sering dilakukan dengan metode pembakaran temperatur tinggi pada alat Total Carbon (TOC). Metode ini memerlukan biaya yang besar, serta keterbatasan jumlah TOC nampaknya menghambat penelitian DOC di Indonesia. Karena itu data dari badan-badan air Indonesia sangat jarang. Tujuan untuk mengaplikasikan alternatif spektrofotometer absorban 254 nm memperkirakan DOC. Sampel diambil saluran drainase (n = 42),...
This study aimed to obtain the candidate isolates of superior decomposer from several plant block areas in Bogor Botanic Gardens (KRB). Those candidates were expected be able utilize fermentation process solid organic waste. The fungi selected based on their abilities produce extracellular enzymes (laccase - Lac, manganese peroxidase MnP, and lignin LiP) using 0.05% guaiacol as a substrate. highest abundance population was found 4 with 9.9 x 106 CFU ml-1, lowest 6 1.9 ml-1 density. Three...
Abstract Forest and land fires in Indonesia have become the main national global concern for last decade. This disaster can cause enormous losses economic, social environmental sectors because it occurs almost every year. The of these was always strongly believed to be human activities (anthropogenic). A definite description what most often fire incidences approximated by pointing out initial that than correlated with kinds ignited fires. traced from hotspot data. Therefore, this study aimed...
Sampah organik dari industri tahu pada umumnya hanya dibuang ke aliran sungai di sekitarnya dan tidak dimanfaatkan oleh masyarakat. Limbah cair mengandung banyak protein, sehingga dalam proses dekomposisi menghasilkan amonia yang menyebabkan bau. Kurangnya peneliti memahami bahwa limbah juga dapat digunakan sebagai substrat Sel Bahan Bakar Mikro (MFC). MFC adalah sistem atau perangkat menggunakan bakteri katalis untuk mengoksidasi bahan anorganik. Elektron diproduksi ditransfer anoda (kutub...
The price of the AB mix is relatively high, so it needed to find another alternative with a more economical price. One alternatives Liquid Organic Fertilizer (LOF). This study aimed know quality LOF made from banana peels and chicken egg shells, effect on water spinach grown in hydroponic wick system, possible use as substitute for mix. experiment consisted three stages. first stage was nutrient analysis raw materials. second production analysis. results fermented fertilizers are called POC...
