Akumulasi Bahan Kering Beberapa Varietas Jagung Hibrida (Zea Mays L.) yang Ditumpangsarikan dengan Ubikayu (Manihot Esculenta Crantz)

Sistem tumpangsari jagung dengan ubikayu merupakan cara untuk mengoptimalisasi penggunaan lahan.Bahan kering tanaman merupakan ukuran yang paling sering digunakan untuk menggambarkan dan mempelajari pertumbuhan tanaman. Penelitian ini bertujuan untuk: 1). mengetahui akumulasi bahan kering tanaman jagung yang ditanam secara monokultur dan tumpangsari dengan ubikayu, 2). mengetahui akumulasi bahan kering beberapa varietas jagung hibrida dalam sistem tumpangsari dengan ubikayu. Penelitian ini dilaksanakan di Kebun Percobaan BPTP, Kecamatan Natar, Kabupaten Lampung Selatan dan Laboratorium Ilmu Tanaaman, Fakultas Pertanian, Universitas Lampung pada bulan November 2012 sampai Maret 2013. Perlakuan disusun secara faktorial dengan petak terbagi dalam Rancangan Acak Kelompok (RAK) dengan 3 ulangan.Petak utama adalah pola pertanaman tumpangsari dan monokultur, sedangkan anak petak adalah varietas tanaman jagung yang terdiri atas P27, DK77, DK85, DK95 dan NK22. Petak percobaan yang digunakan pada penelitian ini berukuran 4 x 3,2 m. Data dianalisis dengan ANOVA dan perbedaan nilai tengah perlakuan ditentukan dengan uji beda nyata jujur pada taraf nyata 5%. Hasil penelitian menunjukkan bahwa akumulasi bahan kering tanaman jagung yang ditanam secara monokultur dan tumpangsarimenunjukkan perbedaan secara nyata; bahan kering pada tanaman jagung secara monokultur memiliki nilai yang lebih besar daripada tanaman yang dibudidayakan secara tumpangsari. Sebagian bahan kering diakumulasikan pada biji diikuti batang,daun, akar, tongkol, kelobot dan malai. Akumulasi bahan kering pada beberapa varietas jagung yang ditanam secara tumpangsari menunjukkan perbedaan tidak nyata. Namun demikianvarietas NK22 menunjukkan akumulasi bahan kering yang paling besar dibandingkan dengan varietas DK85, DK77, DK95 dan P27

Electrochemical Performance of Laser Modified Zinc Electrode

In this work CO2 laser has been utilized to produce textured surface in zinc foil to use in electrochemical cells as a cathode, the modified surface was obtained by making two parallel lines in 1mm, using CO2 laser with (?=10600nm) and power of 90 watts and 10mm/s speed. The experimental evidence of the effect of surface texturing on the performance of the electrochemical cell was demonstrated and investigated. The results show considerable increase in cell voltage with the textured cathode comported to the planar one, also the performance of cell with the textured cathode is more stable

Misuse of antibiotics in Iraq: A review of Iraqi published studies

Misuse of antibiotics is one of the health problems worldwide. In Iraq, prevalence of self- medication with antibiotics increases resistant organisms, this will lead to bad impacts on health and economic aspects in the future. Aim of study is to review the published articles on the antibiotics misuse in Iraq, in   addition to assess the level of the population’s knowledge towards   antibiotics misuse and the suggested recommendation to reduce this problem. Method: In this study 12 articles conducted in different regions of Iraq were reviewed to   assess antibiotic misuse in a period from 2014-2020.Results: The results demonstrated high prevalence of antibiotic misuse among Iraqi population ranging from (45%- 92%). In addition, poor knowledge among   population towards antibiotics misuse also reported. Bad attitudes of pharmacists and physicians regarding antibiotics prescribing and dispensing were registered. Conclusion:  The review focuses on important health issue in Iraq that effect on health & economic system. New legislations and restriction need to apply to limit this problem

Electronically Beam-Steered Dielectric Resonator Antenna Array for Millimeter-Wave Applications

This paper presents a compact 2×2 dielectric resonator antenna (DRA) array with two-dimensional beam-steering capabilities for modern wireless communication systems. The design employs high-permittivity materials (ε = 9.9 for the DRA and εₛ = 3.66 for the substrate) and a four-way microstrip feed network with integrated phase shifters to enable directional beam control in both the X- and Y-planes. The proposed array achieves beam steering up to ±15° while maintaining circular polarization (CP) across the steering range. The DRA dimensions are optimized using the dielectric waveguide model (DWM) and validated through CST eigenmode simulations. Experimental results demonstrate efficient beam steering with low insertion loss, stable impedance matching, and robust polarization performance, making the proposed array well-suited for millimeter-wave 5G and beyond-5G applications

Ground Water Quality Assessment Using the Water Quality Index, Iraq

Water Quality Index (WQI) has been applying in the present study to assess suitability of groundwater quality for drinking purposes in Amara city, southern Iraq. This was carried out by subjecting twelve groundwater samples, collected from different sites to comprehensive physic-chemical analysis. Ten parameters have been considered for calculating the WQI such as; pH, electrical conductivity, total dissolved solids, sodium, potassium, calcium, magnesium, chloride, sulphate and nitrate. The WQI values shows that 16.66% of water samples falls in good water categories and the others (83.66%) ranged from poor water to unsuitable for drinking purposes under normal conditions and further action for salinity control is required. The high value of WQI at this study has been found to be mainly due to the higher values of EC, TDS, SO4-2, Ca+2, Mg+2 and Cl- where it was found that there is a very high correlation coefficient between them
