Abstract

Obesity is a rapidly emerging nutritional problem worldwide and adolescents are no exception. Based on WHO studies, in 2015 about 2.3 billion adolescents aged 15 years and over were overweight and of these, more than 700 million were obese. Objective: This counseling activity aims to increase the understanding and awareness of SMA Negeri 1 Sukatani students regarding the importance of maintaining ideal body weight and being able to know and utilize herbal plants to reduce and maintain ideal body weight. Methods: Counseling is carried out by presenting material about the dangers of obesity and weight loss herbal plants and conducting demonstrations of making processed herbal weight loss plants. The activity was carried out for 120 minutes, consisting of 10 minutes of pretest, 60 minutes of material delivery and question and answer session, 40 minutes of demonstration and then ended with a 10-minute posttest. Results: Based on the evaluation results using the pretest method before carrying out the activity, the overall average value obtained by the students was 74.35% and based on the posttest results after carrying out the activity, the overall average value obtained by the students was 93.48%. This shows that counseling activities can increase the knowledge of participants very significantly. Conclusion: Participants' knowledge about the dangers of obesity and weight loss herbal plants increased after education on the use of herbal plants to maintain ideal body weight.

Abstract

Kulit pisang raja (Musa x paradisiaca L.) merupakan limbah pertanian yang mengandung senyawa metabolit sekunder yang berpotensi sebagai antioksidan alami. Penelitian ini bertujuan mengetahui karakteristik ekstrak etanol 96% kulit pisang raja serta aktivitas antioksidannya menggunakan metode DPPH dan ABTS, dan membandingkan nilai IC50 yang diperoleh dari kedua metode. Simplisia diperoleh melalui liofilisasi, kemudian diekstraksi dengan metode maserasi menggunakan etanol 96%. Ekstrak memiliki rendemen 14,67%, berbentuk kental, berwarna hijau kecoklatan, berbau khas, dan mengandung alkaloid, flavonoid, tanin, dan saponin, sedangkan steroid tidak terdeteksi. Parameter mutu ekstrak memenuhi persyaratan kadar sari larut etanol (60%) dan kadar abu (1,5%), namun susut pengeringan (48%) tidak memenuhi persyaratan. Hasil kromatografi lapis tipis menunjukkan nilai Rf ekstrak yang mendekati standar kuersetin. Nilai IC50 metode DPPH sebesar 58,522±0,016 ppm dan metode ABTS sebesar 59,300±0,169 ppm, keduanya termasuk kategori antioksidan kuat. Hasil uji Wilcoxon Signed Rank Test menunjukkan tidak terdapat perbedaan signifikan antara kedua metode (p=0,109). Dapat disimpulkan bahwa ekstrak etanol 96% kulit pisang raja memiliki aktivitas antioksidan kuat dengan hasil pengukuran yang sebanding antara metode DPPH dan ABTS.
