One of the factors that can affect changes in capacity a reservoir is amount sedimentation settles at bottom reservoir. Several reservoirs Indonesia have experienced shallowing due to sedimentation. The increase rate caused by high land erosion. Land erosion comes from use River Basin Area. benefits Wlingi Reservoir are as flood controller 2.37 m3/s, irrigation supply 13,600 hectares, power plant drive turbine PLTA unit with 2 x 27 MW. In this study, data ESRI satellite imagery, which...

The storage capacity of the reservoir is affected by poor management Watershed (DTA), which in turn influences erosion and sedimentation levels. In 1972, rate at Sutami Reservoir was 0,18 mm/year, rising to 1.44 mm/year 2022. This data reflects a significant increase within watershed, highlighting need for effective watershed modeling. Soil Water Assessment Tool (SWAT) commonly used assessment. study aims predict rates using SWAT evaluate accuracy its simulations through calibration...

This research investigates planting strategies to optimize productivity and conserve soil, focusing on potatoes onions grown erosion-prone land. Cross versus perpendicular plantings is evaluated using the MOORA (Multi-Objective Optimization Based Ratio Analysis) method based erosion rates, crop productivity, economic outcomes. Meanwhile, data from six experimental contour plots are analyzed. The measurements for sediment runoff carried out a dual-bucket system. After calculations, highest...

Rhizobia are bacteria that symbiosis with host plant, as shown in the root nodules formation, and provide nitrogen can be absorbed by plants greater quantities than rhizobacteria. Available Nitrogen, which plants, is essential requirement for plant growth because its role increasing yield quality, hence it needed other nutrients. The study aimed to determine macroscopic microscopic diversity of rhizobia isolates from groundnut their potential PGPRs, identify 16S rRNA best PGPRs molecularly....

Bacillus altitudinis P-10 was isolated from the rhizosphere of rice grown in an organic field and provides strong antagonism against bacterial blight caused by Xanthomonas oryzae pv. rice. Herein, we provide complete genome sequence a possible explanation antibiotic function strain.

Abstract. Sulardiono B, Hartoko A, Aini AN, Wulandari D, Budiharjo A. 2021. Genetic diversity of commercial sea cucumbers Stichopus (Echinoderm: Stichopodidae) based on DNA Barcoding in Karimunjawa, Indonesia. Biodiversitas 23: 922-927. barcoding has proven a sufficient tool for species identification varied groups marine invertebrates, including crustaceans, mollusks, polychaetes, and echinoderms. The outdated system morphological the spp. group is generally color patterns, causing...

Soft corals can produce bioactive compounds that act as antibacterials. Sinularia sp. is a soft coral antibacterial compounds. Symbion bacteria are tend to be the same their host. The use of symbiont an alternative exploit potential without harming marine life. This study aims determine obtained from in inhibiting growth Propionibacterium acnes and Staphylococcus epidermidis . activity test was carried out by agar diffusion method using disc paper. Antibacterial indicated formation clear...

The Wonogiri Reservoir capacity decreases rapidly, caused by serious sedimentation problems. In 2007, JICA was proposed a sediment storage reservoir with new spillway for the purpose of flushing / sluicing from Keduang River. Due to change and system, it requires sustainable operation technique. This technique is aimed minimize deviation between input output sediments. main objective this study explore optimal minimizing trap. CSUDP incremental dynamic programming procedure used model...

Rawa Pening Lake is one of fifteen priority lakes. The problem in the rapid sedimentation rate and blooming water hyacinth which has an impact on decreasing storage capacity quality. handling not shown significant results. Therefore, that it needs to innovate improvement maintenance Catchment Area never done form small dam development catchment area. construction a area can temporarily hold prevent sediment from entering lake. purpose this research analyse influence dams Lake. Sedimentation...

The lateral transfer of symbiotic genes converting a predisposed soil bacteria into legume symbiont has occurred repeatedly and independently during the evolution rhizobia. We experimented plasmid between Bradyrhizobium strains. originality DOA9 donor is that it harbours mega-plasmid (pDOA9) containing nod, nif T3SS while ORS278 recipient unique property inducing nodules on some Aeschynomene species in absence Nod factors (NFs). observed chimeric strain ORS278-pDOA9* lost its ability to...

Abstract The increasing sedimentation of Mrica reservoir shows that the control has not been effective. made include disposal sediments settle in by dredging or flushing. However, results are optimal. This is caused large volume sediment entering each year. controlling goes into also carried out conducting a watershed conservation program and building check dam upstream reservoir. existing still less effective sediments, especially suspended load transported river. Therefore this study was...

Dalam perhitungan inflow waduk sering digunakan persamaan neraca air yang menggunakan data seri laporan harian operasi waduk, evaporasi dan curah hujan diwaduk, lengkung H-V-A waduk. Pada pengamatan series pengukuran kapasitas tampungan dapat terjadi kesalahan disebabkan karena faktor manusia maupun alat, hal ini akan menyebabkan pula pada besarnya dihasilkan. Lebih lanjut di dalam perencanaan, diperlukan sebagai input pemodelan optimasi sedimentasi sehingga keakuratan datanya sangat...

Waduk Gondang berada di Kabupaten Karanganyar merupakan salah satu Proyek Strategis Nasional (PSN). dibangun dalam rangka mendukung ketahanan pangan sebagai infrastruktur penyedia air irigasi dan memenuhi kebutuhan baku wilayah Sragen. Penelitian ini dilakukan untuk memprediksi sedimen yang mengendap waduk pola distribusi sedimen, sehingga dapat digunakan acuan kegiatan pemeliharaan optimal menjaga keberlanjutan fungsi waduk. Dalam studi perhitungan berdasarkan erosi lahan terjadi dengan...
