Abstract

In Indonesia, chocolate products are often associated with high sweetness, leading to distorted consumer perceptions of couverture chocolate, which ideally balances acidity, bitterness, and sweetness. This study aimed to evaluate consumer acceptance of six chocolate couverture formulations in the Special Region of Yogyakarta (DIY) and identify the most preferred formulation based on a balanced sensory profile. Using convenience sampling, 500 untrained panelists aged 15–60 years were selected across five districts in DIY Province. Participants evaluated sweetness, bitterness, acidity, aroma, texture, and overall acceptability through hedonic and ranking tests. Physicochemical parameters (pH, viscosity, and hardness) were also measured to support sensory findings. Results showed that formulations F1 and F2 achieved the highest overall acceptability scores due to moderate bitterness and acidity, preferred sweetness, and smoother texture. The ranking test confirmed these results, with F1 and F2 recording the lowest mean ranks. Physicochemical analysis supported these findings, showing higher pH (6.68 and 6.63), moderate viscosity (6,580 and 5,140cP), and lower hardness (46.83 and 50.52 N). Consumer age significantly influenced preference, with younger respondents favoring sweeter and softer chocolate. These findings emphasize the importance of optimizing sensory and textural attributes to meet diverse consumer expectations. Keywords:  consumer acceptance; consumer preference; chocolate; sensory evaluation

Abstract

The escalating global energy demand and the depletion of fossil fuel reserves have accelerated the pursuit of sustainable bioenergy alternatives. Bioethanol is widely recognized as a promising candidate; however, its production continues to depend predominantly on food-based substrates such as cassava and molasses, thereby exacerbating food vs fuel dilemmas. Consequently, lignocellulosic biomass has emerged as a viable alternative owing to its abundance and non-food nature. Among potential resources, bamboo shoots constitute a particularly strategic feedstock, characterized by high cellulose (33–45%) and hemicellulose (23–30%) contents, coupled with an exceptionally low lignin fraction (0.89%), which minimizes the requirement for energy- and cost-intensive pretreatment. Their rapid growth further reinforces their suitability as a renewable and underexploited biomass source. The present study undertakes a systematic literature review to assess the potential of bamboo shoots for bioethanol production via Simultaneous Saccharification and Co-Fermentation (SSCF). Specifically, it seeks to: (i) elucidate global research trends in SSCF through bibliometric analysis, (ii) identify knowledge gaps concerning the utilization of bamboo shoots, and (iii) propose future research directions to enhance SSCF efficiency. Bibliometric analysis conducted with VOSviewer, encompassing publications from 2006 to 2025, reveals growing scholarly focus on SSCF, particularly in relation to fermentation, enzymatic hydrolysis, and lignocellulosic feedstocks. Notably, the complete absence of “bamboo shoot” as a keyword across the dataset signifies a critical research gap. This gap underscores the necessity for rigorous experimental investigations and the development of predictive simulation models employing bamboo shoots in SSCF, with the aim of optimizing ethanol yields, elucidating key process dynamics, and advancing sustainable bioethanol production. Keywords: bamboo shoot, bioethanol, simulation, simultaneous saccharification and co-fermentation (SSCF)

Abstract

Grouper is a high-value fishery commodity with increasing demand in both domestic and international markets, necessitating a stable raw material supply to support sustainable processing activities. However, feasibility assessments for developing grouper processing industries in Indonesia rarely prioritize raw material availability, despite this factor being essential for maintaining consistent production. This study evaluates the feasibility of establishing a grouper processing industry in Java by integrating cross-regional supply mapping with an inventory control analysis based on the Safety Stock (SS) and Reorder Point (ROP) approaches. A mixed-methods design was used, combining semi-structured interviews, field observations at ten major supply points along the northern coast of Java, and analysis of twelve months of supply and demand data. Findings indicate that the total monthly grouper supply reaches approximately 254 tons, while industrial requirements are around 50 tons. Cold chain capacity, logistics conditions, and the distance of distribution influence price differences across regions. Seasonal fluctuations can be managed by relying on both capture fisheries and floating net cage aquaculture, which help maintain a consistent supply throughout the year. A simulation using an SS value of 602 kilograms and an ROP value of 2,402 kilograms demonstrated that no stock outs occurred during a ten-day evaluation. Overall, the study confirms that the supply of grouper raw materials in Java is stable, feasible, and capable of supporting the growth of processing industries, providing a practical basis for future supply chain planning. These findings offer guidance for policymakers and industry stakeholders nationwide. Keywords: grouper supply chain, raw-material feasibility, inventory control, safety stock, reorder point

Abstract

This research was conducted in order to evaluate the drying prosess using the Moisture Ratio (MR) drying model approach among Newton, Page, Henderson-Pabis and Midili. The thin-layer drying experiment was carried out in a Wirastar FDH10 food dehydrator at the constant temperature of 60°C for 23 h. The main responses, i.e, weight loss, moisture content and water activity (aw) were measured during the process. All data analysis and mathematical modeling was executed with the Microsoft Excel Analysis Tools Solver Add-In. The final weight of the dried apple slices was decreased by 80.2%, and a target moisture content in the range of 6–8% with a final water activity value of aw = 0.431 was also obtained. Comparing the models, Midili model turned to be the most adequate for describing these data as it presented the highest value of  R2 =0.9804 and low values for SSE and RMSE. The empirical equation for the Midili model was MR = 1.000 exp(-0.342* ) + 0.0038*t. The model was validated which showed a good agreement, and the necessary time to dry from 84.4% on wet basis to 6.4% on wet basis is predicted at 11.5 h. This is a 42.5% increase in the time effectivity, which presents definite progress. Keywords: apple slices, drying model, moisture ratio, thin layer drying

Abstract

Commercial hard capsules are primarily manufactured from bovine or porcine gelatine, which often restricts consumer choice owing to religious concerns and vegetarian lifestyles. Konjac glucomannan demonstrates superiority as a gelling and film-forming material, making it a highly potential gelatin substitute in the manufacture of hard capsules. The objectives of this study was to design and determine the optimum conditions for a hard capsule formula based on konjac glucomannan and carrageenan. This study was employed response surface methodology (RSM). The independent variables analyzed were the ratios of konjac glucomannan (2.5%, 3%, and 3.5%; X1), carrageenan (1.5%, 2.0%, and 2.5%; X2), and glycerol (0, 0.125%, and 0.250%; X3). The dependent response variables analysed were capsule moisture content and disintegration time. The moisture content ranged from 5.6% to 15.9%, indicating that higher ratios of konjac glucomannan and glycerol resulted in higher capsule moisture content. Capsule disintegration time ranged from 10.12 to 24.25 min, indicating that a higher glycerol ratio accelerated the hard capsule destruction time. The capsule moisture content and disintegration time were significantly influenced by the raw material used and the resulting capsule specifications. Keywords: carrageenan, formula optimization, hard capsule, konjac glucomannan

Abstract

Blockchain is currently a popular technology for ensuring data security and has the potential to be used across various sectors, especially in the supply chain. Traceability of information is an essential characteristic of blockchain in agricultural commodity supply chains, such as the mangosteen export supply chain, which faces challenges of a long distribution chain and a lack of digitization in the supply chain process, making traceability critical. The objectives of this study were to identify supporting and inhibiting factors and to assess the readiness of actors and stakeholders to adopt blockchain technology. Respondents were selected using purposive sampling, involving 19 key actors and stakeholders. Data were collected and analysed using the TRI method to measure the level of readiness to adopt blockchain technology. This study shows that the main obstacles identified include concerns about implementation and changes in work culture resulting from limited resources, regulations, and high implementation costs. Meanwhile, the main supporting factors are actors' awareness of the importance of digitization, the potential for transparent and efficient recording, and the ease of tracking. The level of readiness to adopt blockchain among mangosteen supply chain actors is moderate, with an average TRI score of 3.44.This category indicates that supply chain actors are beginning to adopt blockchain technology, but there are still obstacles to be addressed. Keywords:  blockchain adoption readiness, horticultural supply chain,  Technology Readiness Index (TRI)

Abstract

   While the traditional food industry holds significant potential, small and medium enterprises (SMEs) continue to struggle with productivity and sustainability challenges. This study develops a productivity measurement model for PT Pangan Barokah Abadi, a traditional Javanese rambak crackers (kerupuk rambak Jawa) producer, by integrating Green Productivity (GP) approach with Green Value Stream Mapping (GVSM). Facing high anergy consumption, emission, and waste generation, the enterprise requires a strategy that balance economic efficiency with environmental performance. GVSM was employed to map value stream across five critical dimensions: energy, water, solid waste, logistics, and emission. Additionally, the Analytical Hierarchy Process (AHP) was utilized to systematically determine and weight green productivity criteria. The resulting model incorporates three core components: the Economic Productivity Index (EPI), the Environmental Productivity Index (EnPI), and the Green Productivity Index (GPI). This framework provides a robust quantitative assessment of operational sustainability and serves as a strategic decision-support tool. The primary contribution of this work is the development of a three-tiered indexing system (EPI, EnPI, and GPI) that translates complex environmental waste data into actionable strategic insights for resource-constrained SMEs. Keywords: analytical hierarchy process, green productivity, green value stream mapping, SMEs, Rambak Crackers

Abstract

As a cornerstone of sustainable development, the circular economy offers a robust mechanism for addressing climate change by maximizing resource utility and minimizing the environmental footprint of agro-industrial processes. This study evaluates the prevalence of linear production pattern within small coffee agro-industries and explores the transition toward a competitive, sustainable system through circular economy principles. Focused on the Ketakasi Cooperative in the Silo District of Jember Regency, the research utilizes a multi-methodological approach – incorporating the Material Circularity Indicator (MCI), the 9R framework, and impact analysis to assess circularity potential. Findings reveal that the cooperative currently operates on predominantly linear model, evidenced by MCI of 0.223. However, substantial potential for circularity exists through the conversion of coffee waste into compost, liquid fertilizer, briquettes, animal feed, and value-added products from defective beans. The 9R analysis demonstrates that implementation of reducing, reusing, and recycling strategies is economically viable, yielding a Net Benefit/Cost ratio greater than1and a payback period less than six months. These results suggest that adopting circular principles can significantly foster a green economy while enhancing climate change resilience within the coffee agro-industrial sector. This research fills a critical gap by offering a site-specific circular economy model for the coffee industry that balances environmental sustainability with immediate economic profitability through innovative waste repurposing. Keywords: circular economy, coffee agroindustry, green economy, Ketakasi Cooperative, resilience
