Abstract

Black rice (Oryza sativa L. indica) is increasingly recognized for its nutritional benefits, including high antioxidant content, dietary fiber, and gluten-free properties. However, limited market penetration persists due to unappealing and uninformative packaging. This study aimed to design and validate a packaging sticker prototype for black rice using a human-centered approach. The research employed the design thinking framework—empathize, define, ideate, prototype, and test—with active participation from 20 farmers, 2 sellers, 2 ergonomics experts, and 20 consumers. Insights from stakeholders highlighted the need for branding authenticity, nutritional claims, halal certification, cooking instructions, and visual elements that balance cultural identity with premium appeal. The resulting prototype featured the brand “Beras Hitam Klaten,” clear health claims, preparation guidance, halal and regulatory information, and a balanced color scheme of earthy brown and gold accents. Validation with the USE Questionnaire demonstrated strong usability performance, with average scores of 4.5 for usefulness, 4.6 for satisfaction, 4.4 for ease of use, and 4.7 for ease of learning. Farmers and sellers reported improved confidence in marketing, while consumers appreciated the clarity and trust cues embedded in the design. The study concludes that integrating human-centered design principles into packaging development can significantly enhance product competitiveness for smallholder agribusiness, with implications for broader adoption in local food systems and SME innovation.

Abstract

Design of Decision Support System (DSS) for final project topic recommendation for ITERA Industrial Engineering students by integrating Case-Based Reasoning (CBR) and Certainty Factor (CF) methods used to support this research. A common problem is when determining the final project research topic, where most students have difficulty finding a topic that is in accordance with their respective fields of expertise. This causes the final project to take longer than the estimated standard time for graduates, which is normally between 4-5 years. The purpose of this study is to assist final year students in determining the final project title that suits their preferences and academic needs. The CBR method is used to search and compare cases based on case similarities with data contained in the database, while the CF value is applied to handle uncertainty and provide a level of confidence in the resulting recommendations. The results show that the integration of these two methods improves the accuracy and relevance of recommendations, as well as providing better transparency through the presentation of Certainty Factor values. System evaluation shows a high level of user satisfaction and a decrease in the time required to determine the final project topic. The design and development of a decision support system for final project topic recommendations was successfully carried out by integrating the Case-based Reasoning and Certainty Factor methods implemented on web hosting, performance evaluation and the impact of system use on user satisfaction showed that users felt satisfied when using the decision support system.

Abstract

Kopi Sejati is a micro, small, and medium enterprise (MSME) in Makassar engaged in the production and sale of locally roasted coffee. Its marketing activities remain limited, relying mainly on exhibitions and direct sales by the owner, with minimal utilization of digital platforms. This study aims to formulate an effective marketing strategy through the integration of SWOT analysis, Marketing Mix (4P), and the Boston Consulting Group (BCG) Matrix. The research employs a descriptive qualitative and quantitative approach, with data obtained from observation, interviews, questionnaires, and sales documentation from 2023–2024.The findings indicate that the most suitable strategy for Kopi Sejati is the Strength–Opportunity (SO) strategy, with total IFAS and EFAS scores of 4.20 and 4.22, placing the business in Quadrant I (aggressive growth strategy). The BCG Matrix identifies Kopi Sejati as a Cash Cow, with a relative market share of 1.25 and an industry growth rate of 4.2%, reflecting a strong yet stable position. The Marketing Mix (4P) analysis highlights product quality and competitive pricing as strengths, while promotion and distribution require improvement. Strengthening digital marketing, forming a dedicated marketing team, and expanding distribution networks are projected to increase market reach by 30% and boost sales by at least 20% annually.
