Canonical JSON (keys sorted, no spaces, UTF-8). Its SHA-256 is the hash on chain.
{"abstract":"Environmental pollution is a significant problem for the government, which triggers them to implement paper bags instead of plastic. The researchers aim to demonstrate and assess the efficiency of pineapple leaf fiber in producing a high-quality paper bag. The present study experimentally investigated the capacity of pineapple leaf fiber as an alternative ingredient for papermaking, focusing on its texture, tensile strength, and thickness. The researchers used a descriptive experimental research design. The primary materials used in the study are pineapple leaf fiber and caustic soda. The researchers used a caliper tool and a spring balance to measure the thickness and the tensile strength of the pineapple leaf paper. The results of the study revealed that pineapple leaf fiber has the potential to serve as an alternative material for making high-quality paper bags. Furthermore, the researchers’ findings show that any fibrous plant has the potential to produce a paper bag.","abstract_source":"original","authors":["Pinky Gumogda","Analyn Bandala","Sandara Midtimbang","Fatima Anip","Nurhayna Lauban","Sittie Ayyesa Bulgao"],"date":"2026-01-14","doi":"10.70838/pemj.510506","id":7024,"issue":5,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"b5075fc3a791d5ddf28fa87e9cda58ad9d39635aafbb57c046147f0eb72dc30b","schema":"scimatic-article/1","title":"Sustainable Paper Bag Innovation: Ananascomosus Leaves as Source of Paper","volume":51}
