Abstract

Learning Media is everything that can be used to convey messages or information in the teaching and learning process so that it can stimulate students' attention and interest in learning. The problem found at SDN 012 is the limited learning media in supporting the teaching and learning process so that it causes children's development and understanding to be less than optimal, such as children having difficulty in recognizing the alphabet and understanding mathematics lessons. This Kukerta activity aims to help students at SDN 012 Pasir Utama Village in recognizing the letters of the alphabet and understanding the divisional material taught in schools. Smart Board and Reading Board Learning Media are strategies used to make it easier for students and students to understand and improve their knowledge. Smart Board media is used in division materials that aim to make it easier for grade 4 students of SDN 012 Rambah Hilir to understand mathematical sciences, especially in division, while reading boards aim to help students, especially grade 1, in alphabet letter recognition and word-to-word spelling.

Abstract

Honey water apple is a horticultural commodity with high water content, making it prone to physical, chemical, and microbiological deterioration during storage. Proper postharvest handling is essential to maintain fruit quality and extend shelf life. This study aimed to determine the optimal concentration of corn starch in an edible coating for preserving honey water apple during storage. The experiment used a non-factorial Completely Randomized Design (CRD) with five corn starch concentrations: P1 (1%), P2 (2%), P3 (3%), P4 (4%), and P5 (5%), with three replications, resulting in 15 experimental units. The observed parameters were weight loss, firmness, total soluble solids, and vitamin C content. The results showed that corn starch concentration significantly affected all observed parameters during storage. The 5% corn starch treatment (P5) was the most effective in maintaining fruit quality after 20 days of storage. Fruits coated with 5% corn starch showed a weight loss of 12.89%, firmness of 4.03 kgf, total soluble solids of 9.3 °Brix, and vitamin C content of 45.83 mg/100 g. Thus, a 5% corn starch edible coating effectively maintained the quality and extended the shelf life of honey water apple.
