ABSTRACT GIVING COLLAGENT SUPPLEMENTS ON ELASTICITYAND MENOPAUSE WOMEN'S SKIN COLOR Background: Physical changes that are generally more visible when a person reaches menopause are changes in skin elasticity and skin color. Reduced water and oil content in the skin will result in reduced skin elasticity resulting in fine lines and wrinkles on the skin and factors that cause skin discoloration are the use of drugs, use of unsafe cosmetics or absorption of ultraviolet (UV) rays. that comes from sunlight. This is caused by reduced collagen production by cells. Due to the reduced amount of collagen, there will also be a reduction in the amount of reduced glycosaminoglycans which then results in reduced skin turgor.Purpose: The purpose of this study was to determine the effect of collagen consumption on skin elasticity and skin color in menopausal women in Cikande, Serang District, Banten Province.Methods: This study used quantitative descriptive statistics with a Quasi-Experimental research design with a One-Group Pretest-Posttest Design approach, which is a quasi-experiment where a group is measured and observed before and after the treatment (treatement). The sample of this research was 20 menopausal women in July in Cikande Village, Serang Regency, Banten Province.Results: Based on the results of the Paired Samples statistical test before and after collagen consumption on skin elasticity, a P value of 0.0118 was obtained from the significance value α => 0.05, this indicates that there is no effect between collagen consumption on skin elasticity. Based on the results of the Paired Samples statistical test before and after collagen consumption on skin color, the P value was obtained of 0.603 from the significance value α => 0.05, this indicates that there is no effect between collagen consumption on skin color.Conclusion: There is no effect of collagen consumption on skin elasticity and skin color in menopausal women in Cikande Village, Serang Regency, Banten Province. Suggestion:It is hoped that further researchers can carry out further research on the effect of collagen consumption on skin elasticity and skin color and for future researchers to be able to continue this research, as well as become a reference in conducting further research and can be developed again, especially on variables that have not been studied. Keywords: Menopause, Collagen, Skin elasticity, Skin color ABSTRAKLatar Belakang:Perubahan fisik yang umumnya lebih terlihat nampak ketika seorang sampai pada masa menopause adalah perubahan terhadap elastisitas kulit dan warna kulit.Berkurangnya kadar air dan minyak didalam kulit akan mengakibatkan berkurangnya elastisitas kulit sehingga timbul garis-garis halus dan kerut-kerut pada kulit dan faktor yang menyebabkan terjadinya perubahan warna kulit adalah penggunaan obat-obatan, penggunaan kosmetik yang tidak aman atau penyerapan sinar ultraviolet (UV) yang berasal dari cahaya matahari. Hal ini disebabkan oleh berkurangnya produksi kolagen yang dilakukan oleh sel. Akibat berkurangnya jumlah kolagen maka akan berkurang pula jumlah pengurangan glycosaminoglycans yang kemudian berakibat pada berkurangnya turgor kulitTujuan: Tujuan penelitian ini untuk mengetahui pengaruh konsumsi kolagen terhadap elastisitas kulit dan warna kulit pada wanita menopause di Kelurahan Cikande Kabupaten Serang Provinsi Banten.Metode: Penelitian ini menggunakan kuantitatif stastistik deskriptif dengan desain penelitian Quasi-Eksperimen dengan pendekatan One-Group Pretest-Posttest Design yang merupakan quasi-experiment dimana sebuah kelompok diukur dan diobservasi sebelum dan setelah perlakuan (treatement).Sample penelitian ini adalah 20 wanita menopause pada bulan Juli di Kelurahan Cikande Kabupaten Serang Provinsi Banten.Hasil Penelitian:Berdasarkan hasil uji Paired Samples statistik sebelum dan sesudah konsumsi kolagen terhadap elastisitas kulit diperoleh nilai P value sebesar 0,0118 dari angka kemaknaan α = > 0,05 hal tersebut menunjukkan tidak ada pengaruh antara konsumsi kolagen terhadap elastisitas kulit. Berdasarkan hasil uji Paired Samples statistik sebelum dan sesudah konsumsi kolagen terhadap warna kulit diperoleh nilai P value sebesar 0,603 dari angka kemaknaan α = > 0,05 hal tersebut menunjukkan tidak ada pengaruh antara konsumsi kolagen terhadap warna kulit.Kesimpulan:Tidak ada pengaruh konsumsi kolagen terhadap elastisitas kulit dan warna kulit pada wanita menopause di di Kelurahan Cikande Kabupaten Serang Provinsi Banten.Saran:Diharapkan bagi peneliti selanjutnya dapat melakukan penelitian lebih lanjutmengenai pengaruh konsumsi kolagen terhadap elastisitas kulit dan warna kulit dan bagi peneliti selanjutnya agar dapat melanjutkan penelitian ini, serta menjadi sebuah acuan dalam melakukan penelitian selanjutnya dan dapat dikembangkan lagi terutama pada variabel-variabel yang belum diteliti. Kata Kunci:Menopause, Kolagen, Elastisitas kulit, Warna kulit.

One of the tasks of the development of children aged 11-15 years is to think in a more abstract and logical way and more idealistic thinking. This ability to think will be disrupted if teenagers have difficulty concentrating during learning. Therefore we need a method that is fun and can make children relax in learning so that they can concentrate their concentration on ongoing learning. One method that can be used is the Murrotal Al-Qur'an therapy. The aim of the study was to determine whether there was any effect of murottal therapy on the concentration of students at Muara Enim 2 MTsN. This study used a quasi-experimental design with the design of the one group pretest posttest. The sample used was all students of class VIII.G at MTsN 2 Muara Enim. The results showed that the average concentration score of class VIII.G students before Murottal therapy was given was 10.84 with a standard deviation of 3.043. While the average concentration score of class VIII.G students after being given murottal therapy was 17.90 with a standard deviation of 1.233, so that the difference in mean concentration scores before and after murottal therapy was 7.06 with a standard deviation of 1.81. Wilcoxon signed ranks test obtained ρ value = 0,000, with a value of α = 0.05 (p <0.05), this shows that there is a significant difference between the concentration of students before and after being given murottal therapy. It is expected that the school can make a policy about the application of murottal therapy in increasing student concentration.
