Abstract

Integrated Rice-Fish Farming System (IRRFS), a conventional rice, poultry, and fish farming system which is widely practiced in south asia, facing the serious obstacles amidst its advantageous contemption. The main challenge is inharmonious water uptake management as the side effect of its area arrangement and inappropriate water irrigation system due to the lack of technology application, leading to the chemical contamination and high water consumption. This paper develop an integrated pH and water level sensors using combined arduino uno-esp 32 microcontroller for the newly designed IRRFS (mina padi) concept and the new concept of IRRFS in terms of area arrangement restructuration with 1:500 diminution scale, aiming to overcome the pest and chemical contamination to the system and high water amount necessity. The integrated pH-water level sensor is designed to maintain daily water uptake of fish ponds and paddy fields to prevent harvest failure. The integrated sensor will instruct either 1st pump or 2nd pump to drain in or drain off the water from the system. The working accuracy is tested by both calibration and the prototype experiment, resulting in the simultaneity working ability of integrated sensors with 1st pump and 2nd pump which possess with high accuracy.

Abstract

Conventional organic waste management methods often lead to environmental degradation and underutilization of valuable resources. In rural areas, such as Polaman Village, limited awareness and inefficient disposal systems exacerbate these issues, thus necessitating innovative and sustainable solutions. This study explores black soldier fly larvae (BSFL) bioconversion as a community-based solution for organic waste management, addresses environmental challenges, and promotes economic empowerment by converting waste into valuable by-products. The study employed a mixed-methods approach, beginning with baseline assessments of waste generation and existing management practices to identify community needs. Educational workshops and hands-on training sessions introduced BSFL bioconversion techniques to local stakeholders. Focus group discussions (FGDs) were conducted to facilitate dialog and collaboration between Polaman residents, the Polaman Resik Sejahtera Waste Bank, and Universitas Diponegoro. Continuous mentoring and pilot trials were conducted to ensure proper adoption and to demonstrate the feasibility of the proposed system. The results reveal that BSFL bioconversion significantly reduces organic waste while producing valuable by-products such as compost and larvae. These findings demonstrate the potential of BSFL bioconversion to align with circular economy principles, contributing to environmental sustainability and economic resilience. The project serves as a scalable model for addressing organic waste challenges in rural communities while advancing the green economy agenda.
