Abstract

Extracts of methanol, ethyl acetate, and n-hexane of four species of Indonesian seagrasses were used to determine the total phenol contents and their antioxidant activities.  Total phenol contents of each extract was determined by spectrophotometer using Follin-Ciocalteu reagent, and the antioxidant activity was measured using 1,1-diphenyl-2-picrylhydrazyl (DPPH).  The profile of fibers of each fresh seagrass was performed according to an enzymatic-gravimetric method. All of methanol extracts contained high number of total phenol, except Syringodium isoetifolium the highest content was found in ethyl acetate extract; so that methanol extracts of Thalassia hemprichii, Cymodocea rotundata, Enhalus acoroides and ethyl acetate extract of Syringodium isoetifolium had the highest activities on scavenging DPPH radical.  The phenol content in tropical seagrasses was tending to soluble in polar and semi-polar solvents. There was no significant different on the content of total fibers, with values ranges was from 14.32 g/100 g to 15.39 g/100 g.  However, the highest content of soluble fiber was found in Enhalus acoroides (8.93 g/100 g) and significantly differed to others.

Abstract

Di Indonesia penderita hipertermi sebanyak 465 (91.0%) dari 511 ibu yang memiliki perabaan untuk menilai hipertermi pada anak mereka sedangkan sisanya 23,1 saja menggunakan thermometer. Penelitian ini bertujuan untuk menganalisis efektivitas kompres air hangat terdahap penurunan suhu tubuh pada anak yang mengalami demam di Praktek Mandiri Bidan Vera Anjarina Karawang 2023 Metode Penelitian: penelitian ini adalah kuantitatif dengan metode penelitian eksperimental menggunakan one group pra-post test design. Banyaknya sampel yang digunakan dalam penelitian ini adalah 30 responden. Hasil Penelitian: Hasil penelitian ini menunjukkan bahwa kompres air hangat efektiv menurunkan suhu tubuh (p-value < 0,05). Sehingga dapat disimpulkan bahwa ada perbedaan suhu tubuh setelah pemberian kompres air hangat pada anak. Kesimpulan: Berdasarkan 30 responden yang diberikan kompres air hangat, dilihat dari hasil uji independent t-test rata-rata penurunan suhu tubuh sebesar 0,94oC.
