This study aims to analyze the production process, marketing strategies, and environmental impacts of sugarcane brown sugar agroindustry at the household scale, using the Haeruddin enterprise located in Latellang Village, Patimpeng District, Bone Regency as a case study. A descriptive qualitative approach was employed, with data collected through in-depth interviews, participatory observation, and document analysis. The results show that the enterprise manages approximately 50 hectares of sugarcane land with productivity ranging from 30–60 tons per hectare, which is below the national average. The production capacity reaches 1–2 tons of sugarcane per day, producing approximately 1 ton of brown sugar daily, and involves local labor in cultivation and processing activities. Marketing is conducted through direct sales and local distributors, with prices ranging from IDR 8,000–10,000 per kilogram, without the use of digital promotion or modern retail channels. From an environmental perspective, the production process generates solid, liquid, and gaseous waste; however, solid waste in the form of bagasse is reused as fuel, while liquid waste and combustion residues are only partially managed. These findings indicate that while the enterprise contributes to employment and the local rural economy, improvements in production efficiency, marketing strategies, and environmental management are required to enhance competitiveness and sustainability. This study provides practical insights for the development of sustainable household-scale sugarcane brown sugar agroindustries in rural areas.

Waste has become a serious environmental problem in Indonesia, which continues to increase along with population growth. The issue of waste management poses serious challenges for the environment, especially in the process of separating organic and inorganic waste. In the field of computer vision, recognising the type and shape of waste through camera images remains a challenge due to variations in shape, colour, and complex lighting conditions. Therefore, this problem utilises Deep Learning technology, which is expected to be widely applied in Indonesia, especially in large cities with high waste volumes. This study aims to distinguish between organic and inorganic waste using the Convolutional Neural Network (CNN) method based on digital images. The developed CNN model was trained to recognise the visual patterns of each type of waste and tested to measure its accuracy. The test results show that the CNN-based classification system is capable of achieving an accuracy rate of 95%, thus proving the effectiveness of this method in supporting artificial intelligence-based automatic waste sorting systems.
