Abstract

Desa Gunungsari merupakan salah satu desa yang hampir masyarakatnya memiliki hewan  ternak yang digunakan sebagai sumber penghasilan sampingan dan utama. Namun keberadaan  hewan ternak ini selain memiliki dampak positif, juga menimbulkan dampak negatif. Adapun  dampak negatif yang ditimbulkan ialah adanya penumpukan kotoran ternak. Hal ini menyebabkan  timbulnya aroma tidak sedap dan masalah kesehatan. Untuk menanggulangi hal ini dilakukan  pengabdian melalui pendampingan pemanfaatan kotoran ternak dengan menggunakan EM4. Pendampingan ini bertujuan untuk memberikan edukasi sehingga masyarakat mitra dapat  mengetahui cara untuk memanfaatkan kotoran ternak yang menumpuk secara mandiri. Pada pengabdian ini dilakukan dengan melakukan demonstrasi langsung pembuatan pupuk menggunakan  EM4 dan kotoran ternak. Selain itu dilakukan pula sesi sharing dengan perwakilan mitra sasaran. Dengan adanya hal ini menyebabkan penambahan pengetahuan sehingga masyarakat mitra yang  lain dapat menerapkannya.

Abstract

Inferior red dragon fruit has the potential as a source of natural dye. This research aimed to examined the quality of natural dye powder as a referenced for optimization. To optimized the formula for natural dye powder based on rejected dragon fruit, and to examined the physical and chemical quality of natural dye powder at the optimum formula. The varied ingredients in this research were ascorbic acid and tween 80. The upper and lower limits of use of both ingredients were 3% and 1% for ascorbic acid, as well as 1% and 0.5% for tween 80. The method used laboratory experimental method and quantitative analysis data. The experimental design used in this research was an experiment with the application of the simplex lattice design (SLD) method, so that several formulas were obtained based on the variation of two factors. Results of the observation data were inputted into the Design-Expert version 13 application so that a regression equation is obtained to determine the optimum formula. All data were presented in tables and graphs and analyzed descriptively. The results showed that F5 (ascorbic acid 3%: tween 80 0.5%) was the optimum formula because it had the highest desirability of 0.998 with a water content of 2.15%; total dissolved solids 9.66%; pH 3.766; L 53.71, a 14.20; b 7.39; dissolved time 61.33 seconds; Chroma 16,00; Hue 27.33ᵒ (red), and anthocyanin content 3,37 mg/mL. On exposure to the sun, outdoor and indoor experienced the highest degradation, namely 30.48% and 0.93%, respectively.
