Prevalensi Anemia Anak Sekolah Dasar Di Daerah Penghasil Dan Bukan Penghasil Sayuran Hijau Di Kabupaten Bogor

Telah dilakukan penelitian secara cross-sectional untuk mengetahui gambaran dan perbedaan konsumsi sayuran hijau dan prevalensi anemia anak SD di daerah penghasil dan bukan penghasil sayuran hijau di Kabupaten Bogor. Penelitian dilakukan di tlga desa penghasil sayuran hijau di Kecamatan Ciampea dan tiga desa bukan penghasil sayuran hijau di Kecamatan Nanggung di wilayah Kabupaten Bogor. Hasil penelitian menunjukkan bahwa anak SD di daerah penghasil sayuran hijau lebih sering dan lebih banyak mengkonsumsi sayuran hijau dibandingkan dengan anak SD di daerah bukan penghasil sayuran hijau (P<0.05). Prevalensi anemia pada anak SD di daerah penghasil sayuran hijau tidak berbeda nyata dengan anak SD di daerah bukan penghasil sayuran hijau. Tetapi rata-rata kadar Hb anak SD di daerah penghasil sayuran hijau berbeda nyata dengan anak SD di daerah bukan penghasil sayuran hijau (12.3 g/dl vs 11.9 g/dl). Faktor-faktor yang berpengaruh nyata pada kadar Hb anak SD di daerah penghasil sayuran hijau ialah frekuensi makan sayur dan konsumsi zat besi dengan koefisien regresi sebesar 0.38009 dan 0.32432. Demikian juga faktor-faktor yang berpengaruh nyata terhadap kadar Hb anak SD di daerah bukan penghasil sayuran hijau ialah konsumsi zat besi dan frekuensi makan sayur dengan koefisien regresi sebesar 0.49240 dan 0.43696

Gait asymmetry assessment using muscle activity signal: a review of current methods

Gait asymmetry is a type of gait characteristics when there is difference in gait parameters statistically, measured bilaterally between left and right limbs. Gait asymmetry assessment is used to observe changes or deviation in gait due to pathological condition, effect of rehabilitation program or to give insight on effect of gait on stability and fall-risk. The assessments of gait asymmetry could be measured by using spatiotemporal, kinetics, kinematics parameters or by analysis of muscle activity signals obtained from surface electromyography (EMG). However, EMG-based assessment for gait asymmetry is not well explored compared to assessment using other gait parameters. This review aims to compare research designs, methods and procedure of previous studies that utilized EMG for gait asymmetry analysis. Therefore, any research in the future that involved gait asymmetry measurement could take note on and produce more reliable findings

Genetics and amino acid composition in woton plants (Sterculia sp.) from Raja Ampat: an alternative nutrition material for fishes

This study aimed to determined the genetic, phylogenetic, and amino acid composition of the woton plant (Sterculia sp) from Raja Ampat that could be utilized in improving nutrition, growth, and fish health. The research used bioinformatics analysis through DNA amplification of the samples of woton plant (WT01 and WT02) with PCR, homology analysis with BLASTN, phylogenetic with Clustal O (1.2.4) program, and analysis of amino acid composition with Expasy Translate Tool, Proparam, Proscale, and compound bioactive with Prosite. The results showed that WT01 (849 bp) 97% identical and WT02 (875 bp) 99% identical were most homologous alignments with Sterculia tragacantha (ID: AY321178.1). WT01 and WT02 had have a 94.21% identity level and were in one group with Sterculia lanceifolia (ID: KR531475.1), Sterculia lanceifolia (ID: KR531477.1) and Sterculia brevissima (ID: KR531473.1). The results used ProtParam that the major amino acid composition in WT01 were 13.9% serine, 12.2% leucine,10% lysine, 7.2% arginine, and 7.2% isoleucine and in WT02 were 12.8% serine, 12.3% leucine, 9.5% lysine, 7.3% arginine, and 7.8% isoleucine. Bioinformatics analysis with Prosite showed that WT01 and WT02 have a small potential of active compound BIG 1(bacterial Ig-like domain 1)

Influence of poly(lactic acid) layer on the physical and antibacterial properties of dry bacterial cellulose sheet for potential acute wound healing materials

Dry bacterial cellulose nanofiber (BC) sheet coated with poly(lactic acid) (PLA) was developed and characterized towards acute wound healing applications. This new approach of PLA coating on BC revealed enhanced physical and antibacterial properties. Commercial BC sheets originated from the manufacturing of nata de coco jelly were dried and coated with the PLA at various concentrations of 2, 4, 6, 8, 10 and 12 % w/v for the purpose of improving the mechanical properties and followed by loading of antiseptic such as benzalkonium chloride (BAC). PLA has been proposed for the use of coating materials at a concentration of 8 %, the biocomposite sheet started exhibiting a low moisture uptake, prolonged swelling in simulated wound fluid solution and high tear (9.17 Nm2/kg) and burst indices (32.5 kPa·m2/g). The 8 % PLA coating revealed porous fiber-like morphology as observed under scanning electron microscope. Therapeutic loading capacity of the BC/8 PLA was substantially higher than the pristine BC. Furthermore strong antimicrobial activities against Staphylococcus aureaus and Escherichia coli were observed for the BC/8PLA biocomposite film. These reports were clearly suggestive of the fact that synthetic biodegradable polymers, such as PLA, may be exploited for the synergistic combination with BC for antimicrobial and acute wound management. This new and modified fiber source material could reduce the dependency on plant based cellulose for more demanding biomedical applications such as wound healing materials, vascular graft, cartilage replacement, drug delivery and tissue engineering

Improved subsurface mapping by enhancing resistivity horizontal resolution

Geotechnical studies are usually used for subsurface, engineering and environmental works. Geophysical study provides supported data in order to save cost and time. The survey was executed to solve engineering problems and environment. Geophysical methods can be used to determine depth of bedrock, thickness of soils, near surface structure such as fault and cavity. A resistivity study is another method of mapping shallow subsurface and become increasingly more widespread in their use. In this paper, resistivity technique will be developing in order to get detail and deeper penetration in shallow subsurface study. By enhancing resistivity horizontal resolution to establish targets, most of the required information can be mapped and the results verified, thus improving the subsurface mapping of the engineering and environmental works. This technique is called as EHR (Enhancing Horizontal Resolution). EHR technique is applied at two sites, miniature model and real site. From the results, EHR technique improves the horizontal changes in subsurface resistivit

All-fiber graphene passively q-switched nanosecond thulium doped fiber laser at 1900 nm

We successfully demonstrated a simple, compact and low cost passive Q-switched Thulium doped fiber laser (TDFL) at long wavelength of 1854.3 nm regions in conjunction with 1552 nm pump excitation. A stable pulse has been generated using graphene film based saturable absorber (SA). The graphene is synthesized by electrochemical exfoliation of graphite at room temperature in 1% sodium dodecyl sulphate (SDS) aqueous solution. Graphene flakes obtained from the process are mixed with polyethylene oxide (PEO) as the host polymer to produce free standing composite thin film which acts as a passive Q-switcher in the TDFL ring cavity. The SA is fabricated by sandwiching the graphene thin film between two fiber connectors. At 1552 nm pump power of 498 mW, a stable pulse train has been observed with a repetition rate of 6.51 kHz and pulse duration of 11.51 µs. The high performances of Q-switched laser suggest that the new type of saturable absorber based on electrochemical exfoliation in conjunction with all-fiber ring cavity configuration is suitable for a Q-switcher near 1900 nm wavelength
