<![CDATA[Soil blocks serve as a solution to reduce plastic waste and soil degradation caused by conventional seedling media. This product offers an environmentally friendly alternative to horticultural seedling media, utilising waste sediment from Lake Rawa Pening and organic biomass, such as chicken manure and cocopeat. However, the supply chain management of this product still faces various potential risks that require appropriate risk management strategies. This study aims to analyse the supply chain mechanism of soil blocks and design a risk mitigation framework using the House of Risk (HoR) method. A case study approach was employed, involving the mapping of the supply chain process based on the Supply Chain Operation Reference (SCOR) model, followed by a risk analysis conducted in two HoR phases. The study was conducted from January to April 2025 at Akar Kreasi Nuswantara, a pioneer in soil block production in Wonosobo Regency. Descriptive and quantitative data analysis methods were used. Data were collected through interviews and questionnaires involving six key informants from the company and analysed using ARP (Aggregate Risk Potential), TEk (Effectiveness of Mitigation Strategy), Dk (Difficulty of Implementation), and ETDk (Effectiveness Times Difficulty). The study identified 24 risk events and 17 risk agents with five top priorities: raw material access disruption, lead time for material readiness, limited supplier availability, delays in product collection by consumers, and obstacles in returning wooden trays. Recommended mitigation strategies include buffer stock management, long-term partnerships, standard operating procedures (SOPs) for production, digital reminder systems, and return incentives for wooden trays.]]>
