Abstract

Penelitian ini adalah mempelajari pemanfaat tanaman umbian ganyong yang  bisa digunakan sebagain bahan dasar pembuatan plastic biodegradable. Ganyong merupakan tumbuh baik di kawasan tropis dan subtropics. Tanaman ganyong di ambil patinya untuk  dijadikan plastic biodegradable. Pada proses pembuatan plastic biodegradable, pati yang sudah kering di campu dengan aquadest dan di tambahkan cmc (carbonyl methyl cellulose) dengan variasi 1;1,25;1,5;1,75;dan 2 gram dengan temperature proses 70oc. Setelahnya di variasikan masing-masing penambahan asam asetat  1 ml dan tanpa penambahan. Didapat hasil yang optimal adalah pada penambahan asam asetat dengan cmc sebanyak  1,5 gram. Hasil dari pengujian tarik, elongasi , ketahanan air, dan biodegradabilitasnya sni telah memenuhi standar sni 7188.7:2016

Abstract

This study is motivated by the low independence of children at PAUD Wafa Humaira, where only 5 out of 13 students show independent abilities. This study aims to improve children's independence and enthusiasm for learning through collage activities. The main objective of this study was to investigate and prove that collage art activities can increase independence and enthusiasm for learning in early childhood at PAUD Wafa Humaira Samarinda. This study used a classroom action research (PTK) method with two cycles. Data were collected through observation, interviews, and documentation. The results showed that collage activities are effective in increasing the independence and enthusiasm of learning in early childhood. There was a significant increase in the second cycle, which indicates that children can develop independence through gradually designed tasks. It can be concluded that collage art activities can increase independence and enthusiasm for learning in early childhood at PAUD Wafa Humaira Samarinda. Through collage activities, children can develop cognitive, social-emotional, and motor skills, and engage in fun and meaningful learning.
