Abstract

Penelitian ini bertujuan untuk memperoleh bubuk sari jambu biji merah dengan kualitas fisik, kimia, dan organoleptik terbaik menggunakan metode Foam-Mat Drying. Produk berbentuk bubuk merupakan salah satu cara pengolahan buah yang lebih praktis dalam penggunaan sehingga akan meningkatkan nilai ekonomisnya. Rancangan percobaan yang digunakan adalah Rancangan Acak Kelompok (RAK) dengan 2 faktor, yaitu konsentrasi dekstrin (5%), (7,5%), dan (10%) dan konsentrasi Tween 80 (0,3%), (0,4%), dan (0,5%). Hasil penelitian menunjukkan bahwa perlakuan terbaik dalam pembuatan bubuk sari jambu biji merah dengan metode foam­mat drying diperoleh dari konsentrasi dekstrin 10% dan Tween 80 0,5% dengan rendemen 24,92%, kedispersian 21,27 detik, tingkat kecerahan/L * 77,58, tingkat kemerahan/a* 12,86, tingkat kekuningan/b* 20,59, kadar gula total 52,95%, dan secara sensori disukai oleh panelis. Technology Of Red Guava (Psidium Guajava L.) Juice Powder Using Foam-Mat Drying MethodA research has been conducted with an objective to obtain red guava (Psidium guajava L.) juice powder with the best physical, chemical, and organoleptic quality using foam-mat drying method. The red guava juice powder is more practical in using and will increase its economic value. The experimental design used was Randomized Complete Block Design with two factors replicated three times, i.e. dextrin concentrations of 5%; 7.5%, and 10%, Tween 80 concentrations of 0.3%; 0.4%; and 0.5%. The results showed that the best treatment was obtained from the dextrin concentration of 10% and Tween 80 concentration of 0.5% with the yield 24.92%, dispersion in 21.27 seconds, the brightness/L * of 77.58, the level of redness/a * of 12.86, the level of yellowish/b of * 20.59, total sugar 53.78%, and preferred sensory properties.

Abstract

Purpose: This research aims to develop and assess the effectiveness of literacy-based storybooks enhanced with augmented reality (AR) as an intervention for the development of executive functions in early childhood. Executive function is a cognitive ability that underlies tasks such as maintaining focus on long-term goals, delaying gratification, and exercising self-control over impulses. Methodology: The research adopts a 4D development model encompassing four main stages: Define (Definition), Design (Planning), Develop (Development), and Disseminate (Dissemination). This learning medium garnered positive responses from users, with children expressing satisfaction with the appeal of the songs and recognizing the excellence of the 3D pictures and activities in the storybook. The research also evaluates the effectiveness of AR-based encyclopedias in enhancing reading literacy comprehension through pre- and post-test designs. Results: The study revealed an increase in knowledge related to expressing songs. Additionally, there was a modest yet significant improvement in the aspect of responsibility. Children exhibited a greater interest in participating in singing activities with the teacher compared to conventional reading and writing activities.
