Abstract

The aim of this studi is to examine the antibacterial activity of aloe vera leaf infuse (Aloe barbadensis Miller) against human pathogens such as Pseudomonas aeroginosa, Salmonella typhi, Staphylococcus aureus, dan Streptococcus pneumonia. Antibacterial activity test of 20, 40, and 60% aloe vera leaf infuse was using agar well diffusion method. The antibacterial activity is indicated by the formation of a clear zone around the wells. All the concentration of aloe vera leaf infuse (Aloe barbadensis Miller) showed signi? cant antibacterial activity against Pseudomonas aeroginosa, Salmonella typhi, Staphylococcus aureus, but did not show antibacterial activity against Streptococcus pneumonia. Aloe vera leaves infuse at a concentration of 60% can inhibit the growth of Pseudomonas aeroginosa indicated by the formation of a clear zone (16.5 mm), the bacteria Salmonella typhi (34 mm), and Staphylococcus aureus (15 mm). The research recommended aloe vera leaf would be suitable for use as antibacterial agent of disease caused by Pseudomonas aeroginosa, Salmonella typhi, and Staphylococcus aureus.

Abstract

This study was aimed at determining the relationship between the Pediculus humanus capitis infestation condition, anemia status and learning achievement in primary school-age children. This study was conducted at SD Bangunharjo Sewon Bantul, Yogyakarta. This study is an observational analytic study with cross sectional design in which the variables are measured in one measurement without intervening. The data obtained through pediculosis examination, Hb examination, and measurement of learning outcomes. The data then were analyzed descriptively presented in tabular form, then performed statistical analysis using the chi-square test. The results show that the students suffering from pediculosis, 57.9% also suffering from anemia and 51.0% having poor category achievement. In line with other researchers, one of the factors that influence one?s learning achievement is the memory factor. Someone?s anemia status can affect one?s memory. The prevalence of Pediculus humanus capitis infestation is 38.3%. Chi-square test showed a significant relationship between Pediculus humanus capitis infestation condition, anemia status, and learning achievement.HUBUNGAN PEDIKULOSIS KAPITIS, STATUS ANEMIA DAN PRESTASI BELAJAR PADA SISWA SEKOLAH DASAR Penelitian ini bertujuan untuk mengetahui hubungan kejadian infestasi Pediculus humanus capitis (kutu kepala) dengan status anemia dan prestasi belajar pada anak usia sekolah dasar. Penelitian ini dilakukan di SD wilayah Bangunharjo Sewon Bantul Yogyakarta. Penelitian ini merupakan penelitian analitik observasional dengan desain cross sectional. Variabel diukur dalam satu kali pengukuran dengan tidak melakukan intervensi. Data penelitian diperoleh melalui pemeriksaan pedikulosis, pemeriksaan Hb, dan pengukuran hasil belajar. Data dianalisa secara deskriptif yang disajikan dalam bentuk tabel, kemudian dilakukan analisis statistik menggunakan Uji chi-square. Hasil penelitian ini menunjukan bahwa menderita pedikulosis sebesar 57,9% menderita anemia dan sebesar 51,0% dengan prestasi belajar kategori kurang baik. Salah satu faktor yang mempengaruhi prestasi belajar seseorang yaitu faktor daya ingat. Status anemia seseorang dapat mempengaruhi daya ingat seseorang. Prevalensi infestasi Pediculus humanus capitis sebesar 38,3%. Uji chi-square menunjukkan adanya hubungan yang signifikan antara kejadian infestasi Pediculus humanus capitis dengan status anemia dan prestasi belajar.

Abstract

This study aims to examine the potential of jamu inggu as an alternative antibacterial herb that can be used against Staphylococcus aureus, Streptococcus pnuemoniae, S. Pyogenes, and Pseudomonas aeruginosa that is causing Upper Respiratory Infections (URI). Antibacteria activity test of jamu inggu was using the Agar diffusion method by Kirby-Bauer. To test jamu inggu antibacterial activity against Staphylococcus aureus, Streptococcus pnuemoniae, S. Pyogenes, and Pseudomonas aeruginosa, the diameter of the test bacteria growth inhibition zone was measured. The formation of a clear zone around the disc indicates that jamu inggu has chemical compounds that are antibacterial against Staphylococcus aureus,while the Pseudomonas aerugenosa, Streptococcus pyogenes, and S. pneumoniae bacteria cannot be inhibited by jamu inggu. It was indicated by no formation of a clear zone around the disc. Result shows that jamu inggu can be used as an alternative source of antibiotics against the Staphylococcus aureus.

Abstract

Plant growth promoting rhizobacteria (PGPR) is a bacterial colonization of plant roots that can stimulate the growth of plants directly or indirectly. The PGPR mechanism indirectly results in plant growth as it suppresses the growth of phytopathogen. This study aims to determine the ability of Pseudomonas sp. and Bacillus sp. in controlling the pathogenic root fungal pathogenic fungi. Isolates in this study were Pseudomonas sp. Crb 3, Crb 17, Crb 17i, Crb 68 and Bacillus sp. Cr 24, Cr 44, Cr 66 co-inoculated with B. japonicum in soybean plants in greenhouses. An antagonistic activity test was performed on all isolates and all isolates showed no antagonistic activity. Treatment of combination of strain Pseudomonas sp.Crb 17, Crb 17i and Bacillus sp. Cr 24 inoculated with B. japonicum suppresses the growth of root rot fungi and increases peroxidase. Therefore, Pseudomonas sp. Crb 17, Crb 17i and Bacillus sp. Cr 24 can be used as a biocontrol agent for pathogenic fungi causing plant root disease.
