Abstract

One part of the influence of technological developments is fishermen's fishing gear. The aim of using modern fishing gear is to make it easier for fishermen to reach a wider range of fishing activities and optimize their catch. However, not all fishing gear used by fishermen can have a positive effect on preserving the aquatic environment. Such as the use of trawl nets, chemicals and explosives can damage the potential of marine resources. It is necessary to understand and raise awareness among fishermen regarding the use of fishing gear that is not environmentally friendly. The Method for Conveying Understanding of the Integration of Environmentally Friendly Fishing Equipment Technology for Fishermen in the city of Padang is a form of Tridharma tertiary service for lecturers at Nahdlatul Ulama University, West Sumatra in creating resources that understand the sustainability of water potential so that they can be utilized sustainably for future generations. The results of this service activity motivate fishermen to work together to protect the aquatic environment by not using fishing gear that can damage the waters and have the potential to protect aquatic resources in the future.

Abstract

The management of rice straw (Oryza sativa) waste in Indonesia, particularly in Pasaman Regency, faces significant challenges due to the widespread practice of open burning, which harms the environment and poses health risks to local communities. Despite this, rice straw holds great potential as an organic compost material that is environmentally friendly and nutrient-rich. This study explores the use of Rhizopus oryzae, a fermentation fungus capable of accelerating the decomposition of rice straw, as an efficient, economical, and sustainable waste management solution. Through fermentation, rice straw can be converted into high-quality compost that enhances soil fertility and agricultural productivity while reducing dependence on chemical fertilizers. This technology is highly relevant in promoting sustainable agriculture and climate change mitigation by lowering greenhouse gas emissions. However, field adoption still faces challenges, particularly in fermentation control and farmer outreach. Therefore, policy support, technical training, and cross-sector collaboration are essential to ensure broad and effective implementation. This approach presents a strategic solution for environmentally friendly agricultural waste management and improving farmer livelihoods in the future.
