Abstract

This study aims to determine the substitution effect of banana peel flour based on the proximate tests (water content, ash, carbohydrate, protein, fat and fiber). This experimental study used Completely Randomized Design (CRD) to find out the best quality of banana skin flour with the substitution level of kepok banana peel as a treatment. There were 4 treatments, F1 (45%), F2 (50%), F3 (55%) and F0 (without kepok banana peel flour). Based on the results of statistical tests using Analysis of Variance (ANOVA and Duncan’s Multiple Range Test, substitution of kepok banana peel flour has a significant effect (p 0.05) on the organoleptic properties. Steamed sponge cake substituted with 50% kepok banana peel flour (F2) was the formula with the highest acceptability compared to other formulas. Formula F2 (50%) showed the water content of 31,60%, ash level 2,78%, fat 5,97%, protein 10,97%, fiber 1,91%, and carbohydrate 48,68%. Kepok banana peel flour can be used as an alternative to diversification of food and increase the nutritional value of steamed sponge cake. Penelitian ini bertujuan untuk mengetahui pengaruh substitusi tepung kulit pisang kepok berdasarkan uji proksimat (kadar air, abu, karbohidrat, protein, lemak dan serat). Penelitian ini merupakan penelitian eksperimental menggunakan Rancangan Acak Lengkap (RAL) untuk mengetahui kualitas tepung kulit pisang terbaik dengan tingkat subsitusi tepung kulit pisang kepok sebagai perlakuan, yaitu F1 (45%), F2 (50%), F3 (55%) dan F0 (tanpa tepung kulit pisang kepok). Berdasarkan hasil uji statistik menggunakan Analysis of Variance (ANOVA) dan Duncan’s Multiple Range Test, substitusi tepung kulit pisang kepok berpengaruh signifikan (P0,05) terhadap hasil organoleptik produk. Bolu kukus yang disubstitusi tepung kulit pisang kepok sebanyak 50% (F2) merupakan formula dengan daya terima paling tinggi dibandingkan dengan formula lain. Formula F2 (50%) memiliki kadar air 31,60%, abu 2,78%, lemak 5,97%, protein 10,97%, serat 1,91%, karbohidrat 48,68%. Tepung kulit pisang kepok dapat dijadikan alternatif sebagai diversifikasi pangan dan meningkatkan nilai gizi pada bolu kukus.

Abstract

The purpose of this study was to get the prediction model which had optimum validity for  estimating body fat percentage of adolescent girls. The design of this study was a Cross Sectional. The sampels were 110 school girls which taken by Stratified Proportional technique. Anthropometric measurements consisted of measurements of age, weight, and height (to obtain the BMI (kg/ m2) and BMI (WHO Z Score)), waist circumference, and skinfold thickness. Body fat percentage was measured using various predictive models. Bivariate analysis used was the correlation test. Multivariate analysis used was multiple linear regression test. The ROC test was used for the validation test to determine the Area Under Curve (AUC) value, sensitivity, specificity, Positive Predictive Value (PVP), Negative Predictive Value (PVN), Likelihood Ratio + or (LR +), and LR-. The  result  of  the study  showed  that the average of body fat percentage of samples was 26,51% ± 5,48%. The prediction model which obtained from multivariate analysis was BFP= 0,991 BMI +0,069 ST+0,249 A -1,703. Based on the validation test, the prediction model of this study had optimum validity in compared with other  prediction  models.  Tujuan dari penelitian ini adalah untuk mendapatkan model prediksi yang memiliki validitas optimal untuk memperkirakan persen lemak tubuhremaja putri. Desain  penelitian adalah Cross Sectional. Sampel yang diambil sebanyak 110 siswi dengan  menggunakan teknik Stratifikasi Proporsi. Pengukuran antropometri terdiri dari pengukuran usia, berat badan dan tinggi badan (untuk mendapatkan nilai IMT (kg/m2) dan IMT WHO Z Score), lingkar pinggang, dan skinfold thickness. Persen lemak tubuh diukur dengan menggunakan berbagai model prediksi. Analisis bivariat menggunakan uji korelasi. Analisis multivariat menggunakan uji regresi linier ganda. Uji ROC digunakan untuk uji validasi untuk mengetahui nilai Area Under Curve (AUC), sensitivitas, spesifisitas, Predictive Value Positif (PVP), Predictive Value Negative (PVN), Likelihood  Ratio + atau  (LR+), dan LR-. Hasil penelitian menunjukkan bahwa rerata persen lemak tubuh   responden adalah  26,51 %   ±  5,48 %. Model prediksi  yang  didapatkan dari hasil multivariat adalah PLT=  0,991 IMT  + 0,069 ST + 0,249 U -1,703. Berdasarkan hasil  uji  validasi, model prediksi tersebut  memiliki validitas optimal jika dibandingkan dengan model prediksi lainnya.
