Abstract

This study explores the price sensitivity of medium-quality rice among low- to middle-income households in Kota Baru Driyorejo, Gresik Regency, Indonesia, using the Van Westendorp Price Sensitivity Meter (PSM). Rice is the staple food for most Indonesians, particularly for low-income households where it fulfills essential caloric needs. This research identifies the acceptable price range for medium-quality rice, revealing critical thresholds: the Point of Marginal Cheapness (PMC) at Rp 10,000, the Point of Marginal Expensiveness (PME) at Rp 12,500, the Optimal Price Point (OPP) at Rp 11,000, and the Indifference Price Point (IPP) at Rp 11,500. These insights highlight the delicate balance between affordability and perceived quality, underscoring the need for strategic pricing to mitigate financial strain on vulnerable populations. A purposive sampling method targeted 335 respondents from households with monthly incomes of IDR 2,000,000 to IDR 3,500,000, ensuring the focus on those most affected by price fluctuations. The findings provide actionable guidance for policymakers and market stakeholders to develop equitable pricing strategies, stabilizing rice consumption and promoting food security. Future research should address production efficiency and expand the scope to other regions and demographics to refine pricing policies and their socioeconomic impact.

Abstract

This study analyses the market potential and financial feasibility of milkfish floss enriched with ulin banana corm, addressing a gap in literature concerning the economic viability of such sustainable food innovations. While prior research confirms the technical suitability of banana corms in food products, their commercial potential remains underexplored. Utilizing a mixed-methods approach, this research gathered qualitative data through in-depth interviews with experts, and quantitative data via a consumer questionnaire (n=70). The findings reveal significant financial promise, with a calculated profit margin of 43.3%, a positive Net Present Value (NPV) of Rp 51 million, an 80.18% Internal Rate of Return (IRR), and a two-year Payback Period (PBP). Consumer analysis indicates strong appreciation for the product's health benefits, natural ingredients, and unique taste, with a high overall acceptability score (3.9/5). However, the primary challenge identified is consumer hesitation due to differences in taste and texture compared to traditional milkfish floss. The discussion concludes that despite this barrier, the product holds strong potential for success, particularly among health-conscious and environmentally aware consumers. To achieve wider market acceptance, the study recommends investing in more efficient processing technology and implementing targeted marketing strategies that emphasize the product's nutritional advantages and sustainability credentials

Abstract

This study developed an innovative shredded milkfish product (abon bandeng) incorporating banana pseudostem (bonggol pisang ulin) in Sidoarjo Regency. Although local milkfish production and available banana biomass are substantial, empirical evidence on hybrid formulations combining animal protein and pseudostem-derived fiber, along with market-based price assessment, remains limited. The study therefore aimed to (1) develop and select the optimal milkfish: banana pseudostem formulation for sensory acceptance, (2) identify the consumer preference drivers for the selected product, and (3) assess preliminary commercial viability using the Price Sensitivity Meter (PSM). Four formulations (100:0, 70:30, 50:50, 30:70) were evaluated via organoleptic testing with 70 respondents; subsequent consumer preference and PSM analyses were conducted. The 50:50 formulation achieved the highest acceptance (mean = 4.014; like rate = 81.43%). ANOVA showed significant differences (p < 0.05) in aroma, texture, and taste across formulations. PSM indicated an acceptable price range of IDR 14,500–20,000 and an optimal price point at IDR 15,500. Taste and nutritional value were key purchase drivers (88.6%), and online marketplaces were the principal distribution channel (45.7%). Findings demonstrate sensory viability and preliminary commercial potential for this hybrid product. This study contributes by integrating sensory optimization and price modeling into hybrid animal–plant product development, while providing an empirically validated formulation and an optimal pricing reference to support circular-economy-based agro-innovation.

Abstract

UD Tata is a tofu producer in Sidoarjo Regency that still faces quality deviations in the form of soft texture, visual damage, and product contamination. This study aimed to analyze tofu production quality control using Statistical Process Control (SPC). A quantitative approach with simple random sampling was applied to 1,000 tofu pieces per day for 20 observation days from a daily production of 10,000 pieces. The analysis employed check sheets, np control charts, Pareto diagrams, cause-and-effect diagrams, and process capability analysis. The results showed 596 soft-texture defects, 486 visually damaged tofu defects, and 443 contamination defects. The np control chart indicated that texture and visual attributes remained under statistical control, while the cleanliness attribute showed one point above the upper control limit on the ninth observation day and therefore required corrective action. The dominant defect was soft tofu texture, accounting for about 40% of total defects. The main causes were related to human factors, methods, materials, machines and equipment, and the work environment. Process capability values for the three attributes were categorized as good at 97.0%, 97.6%, and 98.0%, respectively.

Abstract

Orthogonal Frequency Division Multiplexing (OFDM) systems require an effective modulation adaptation mechanism to maintain transmission reliability over dynamic and noise-affected channels. This study proposes a machine learning–based adaptive modulation method using Naive Bayes classification to select the most appropriate modulation scheme—BPSK, QPSK, or 16-QAM—based on Signal-to-Noise Ratio (SNR) values. The Naive Bayes model is trained using the probabilistic performance distributions of each modulation scheme, enabling optimal modulation mode prediction under various channel conditions. Simulation results demonstrate that the proposed adaptive method achieves a lower Bit Error Rate (BER) compared to fixed modulation schemes, particularly under low to medium SNR conditions. Furthermore, the Naive Bayes–based approach exhibits more stable performance, especially in recovering transmitted messages. BER curves and demodulated message results indicate that the artificial intelligence–based adaptive scheme using Naive Bayes improves the reliability of transmitting the text message “HELLO WORLD” across an SNR range of –5 dB to 15 dB. These findings confirm that integrating intelligent methods into adaptive OFDM modulation provides an effective solution for wireless communication in fluctuating channel environments.
