Latar Belakang: Usia anak yang mengalami infeksi pada saluran pernapasan menyebabkan produksi mukus berlebih. Dahak yang menumpuk sampai kental akan sulit dikeluarkan. Dengan adanya keadaan tersebut menyebabkan pasien mengalami sesak nafas, supaya tidak sampai ke komplikasi dibutuhkan penanganan salah satunya adalah pengeluaran dahak dengan cara fisioterapi dada. Tujuan : Penelitian ini untuk mengatahui pengaruh fisioterapi dada terhadap bersihan jalan nafas. Metode : Penelitian ini merupakan Quasi Eksperiment jenis One Group Pretest Postest design, penelitian dianalisis menggunakan uji wilcoxon, pengambilan sampel sebanyak 18 responden dengan teknik purposive sampling. Berdasarkan analisa data hasil statistik didapatkan nilai p value < 0,05 yaitu p value = 0,001 yang berarti dapat diambil kesimpulan terdapat pengaruh fisiterapi dada terhadap penurunan frekuesi pernapasan dan nilai p value = 0,02 yang berarti terdapat perbedaan hasil bersihan jalan nafas sebelum dan sesudah dilakukan fisioterapi dada. Kesimpulan setelah dilakukan fisioterapi dada dapat bermanfaat untuk mengeluarkan dahak pada anak yang sedang mengalami ketidakefektifan bersihan jalan nafas.

Skin aging is a problem for women caused by external factors, namely exposure to free radicals such as sunlight, antiaging cosmetic products containing antioxidants have been widely circulated to maintain skin health from the effects of free radicals. The content of antioxidant chemical compounds in the purslane plant (Portulaca oleracea L.) is believed to be able to prevent free radicals. Purslane plant extract serum preparations were made by formulating preparations with ingredients such as HPMC, chitosan, tween 80. Furthermore, antioxidant testing of extracts and preparations of serum spray formulas was carried out using the DPPH method, after which evaluation of the preparations included homogeneity, pH, adhesion, viscosity, and hedonic. The preparation of purslane plant extract serum in the spray gel preparation produces a brownish green color, has a slightly sour smell and has a soft texture. The resulting viscosity in the serum ranged from 1330 - 1362 cPs with a pH value in the range of 5.67 - 5.72. From the hedonic test carried out, the results obtained were that the color and aroma were less favored by the panelists while for the convenience of using spray gel the panelists liked the texture of all purslane (Portulaca oleracea L.) plant extract formulas. Based on this research, the IC50 value of purslane (Portulaca oleracea L.) plant extract was 132.87 ppm, while the formula had an IC50 value of 83.91 ppm. Therefore, antiaging serum in spray gel formulation has stronger antioxidant activity than purslane (Portulaca oleracea L.) plant extract.
