Abstract

The purpose of this study was to build science learning based on a hydroponic project as an effort to enhance junior high school student’s scientific literacy in Banten Province. A descriptive quantitative design included thirteen ninth grade students. Scientific literacy was measured during pre-test/post-test, which was reinforced with engagement and attitudes towards science observation. Results demonstrated significant increases in average scores from 66.92 to 95.38 and an average improvement of 44.2%. Learners with low pre-knowledge gained most (66.67%). The hydroponics program offered real life experiences, reinforced thinking like a scientist, promoted teamwork and nicely built scientific literacy and 21st century skills in students.

Abstract

The use of plastic polybags in mangrove nurseries poses environmental problems because they are not easily biodegradable. The National Waste Management Information System (SIPSN) estimates that Indonesia's waste generation will reach 50.06 million tons in 2025, with approximately 40% unmanaged and most of it ending up polluting the sea. Therefore, an alternative planting medium is needed for mangrove seed cultivation. The methods used include carrageenan extraction, bioplastic film production, ecopolybag printing, and physical and biodegradation testing. Two formulations were tested: one without chitosan and one with the addition of 3 grams of chitosan. The results showed that the ecopolybag without chitosan was more flexible and dissolved in three hours, while the chitosan ecopolybag was stiffer and dissolved in three and a half hours. Both formulations completely degraded within seven days. This research proves that Eucheuma cottoni can be used as a base material for effective and environmentally friendly biodegradable ecopolybags to support mangrove restoration
