Mothers also expressed willingness to apply the knowledge gained in daily feeding practices at home. This program is expected to increase family awareness of balanced nutrition and encourage the use of local food sources to support optimal child growth and nutritional status improvement.

Initial survey results show that consumers in the Makale region have specific preferences for tempeh packaging and quality, but business actors have not incorporated these preferences into their production and marketing strategies. This gap calls for an intervention to develop a strategy based on a systematic, contextual mapping of consumer preferences. Using a mixed methods approach with an explanatory sequential design, the study was conducted in two stages: first, quantitative data collection and analysis, followed by qualitative data collection and analysis to clarify and deepen the results. The study found that consumer preferences for Jeslyn tempeh are primarily influenced by sensory qualities (taste, texture, aroma), cleanliness, affordability, hygienic packaging, distribution ease, and promotion. The Likert scale analysis showed that most indicators had an average value above 4.20 (percentage index > 84%), indicating high to very high consumer satisfaction. Taste (mean 4.52; index 90.4%) and texture (mean 4.44; index 88.8%) were the most influential factors, followed by price and cleanliness. Consumer loyalty is built through consistent quality and emotional attachment to local products. Producers should maintain product quality, improve hygiene, introduce simple innovations, and use social media for cost-effective promotion.

The Student Organization Capacity Building Program (PPKO) of the PTI FKIP UMS is a community service initiative that aims to increase the added value of tempeh products in Sentono Village, Karangdowo District, Klaten Regency, with a focus on product innovation, particularly tempeh nuggets. Sentono Village has long been known as one of the largest tempeh production centers in Klaten, with more than 26 active tempeh producers. However, these producers face significant challenges in the form of conventional marketing and a lack of diversification in tempeh products, which has resulted in the village's economic potential not being fully realized. This activity was designed to address these issues by actively involving the community, including intensive training in tempe nugget production, hands-on practice under the guidance of facilitators, and interactive question and answer sessions to solve practical problems. To measure the effectiveness of the program, an evaluation was conducted using pre-tests and post-tests to quantitatively measure the increase in participants' knowledge and skills. The results of this evaluation show a significant increase in participants' knowledge and skills, proving that product innovation can be a strategic solution to improve the competitiveness of MSMEs in the modern era.

The Hazard and Operability (HAZOP) methodology is a qualitative risk analysis technique commonly used to detect potential work hazards. CV. Suryadi Sentosa, also known as Bapak Suryadi's Home Tempe Industry, is a home-based business that produces tempeh. Almost all of the production procedures are still carried out manually, and occupational accident analysis measures have not been implemented. The factory conditions indicate inadequate lighting and ventilation, as well as relatively slippery floors. It is also observed that the industry workers do not pay much attention to their posture, and they do not use personal protective equipment (PPE). This research was conducted directly at the CV. Suryadi Sentosa Tempe Factory, using interviews and observations of seven workers involved in the production process. The steps taken in this study are compiling the sequence of the production process. By using a Hazard and Operability (HAZOP) worksheet, identify potential risks, conduct risk control analysis, monitor and evaluate, implement improvements, and draw conclusions. The analysis found 9 stages of tempeh production at Mr. Suryadi's facility. Several improvements are needed, including involving several workers to handle soybean processing, creating ventilation to provide good and healthy air circulation for workers, adding lighting as a light source so that workers can perform their tasks comfortably, and using ergonomic chairs and work tables to prevent fatigue and increase factory productivity.

Tofu is one of the most widely consumed foodstuffs in Indonesia, enjoyed by nearly all social groups due to its affordability, nutritional value, and availability. As a processed product derived from soybeans, tofu has been an integral part of Indonesian diets for generations, with its consumption evenly distributed across regions. This study focuses on analyzing tofu consumption patterns in the Tenggarong sub-district, Kutai Kartanegara Regency, while specifically examining the influence of tofu and tempeh prices on tofu demand. Tempeh is included in the analysis as a comparative product due to its similarity in raw materials and market segment. The research employs a quantitative approach using multiple linear regression to determine the effect of the independent variables—price of tofu (X1) and price of tempeh (X2)—on the dependent variable, tofu demand (Y). Data were collected from relevant local sources through market surveys and secondary data records. The results indicate that both X1 and X2 have a measurable influence on Y, as reflected in the regression equation: Y = -50,178.37 + 20.48X1 + 2,488.09X2. The positive coefficient for tofu price suggests that, contrary to typical demand theory, an increase in tofu price in this specific market segment is associated with higher demand, which may indicate the influence of perceived quality or brand loyalty. Similarly, the positive coefficient for tempeh price implies that as tempeh becomes more expensive, consumers may substitute it with tofu, thereby increasing tofu demand. These findings highlight unique consumer behavior patterns in Tenggarong that may be influenced by cultural preferences, income stability, and market conditions. The study concludes that price dynamics between tofu and its substitute product, tempeh, play a significant role in shaping tofu consumption.

Tempeh, as one of Indonesia's traditional fermented foods, plays a vital role in providing affordable vegetable protein and contains various essential nutrients such as vitamin B12, folic acid, and fiber. Tempeh's uniqueness lies in the fermentation process involving local microorganisms that thrive in soybeans. Tempeh from Bayung Lencir, South Sumatra, is known for its traditional production process, which uses no starter culture. This results in a unique microbiota that has not been widely studied during fermentation. Therefore, this study focused on identifying the microorganisms involved in the tempeh fermentation process. The results showed that Rhizopus oligosporus is the primary microorganism responsible for the formation of tempeh's texture and increasing its nutritional value through the production of proteolytic and lipolytic enzymes that aid in the digestion of protein and fat. Furthermore, lactic acid bacteria such as Lactobacillus plantarum and Pediococcus spp. play a crucial role in creating a more acidic environment, thereby reducing the risk of pathogenic microorganism growth and maintaining product safety. However, an uncontrolled fermentation process can also result in contamination by harmful microorganisms, such as Aspergillus niger and Penicillium spp., which can affect the quality of tempeh and potentially produce mycotoxins that are harmful to health. The use of PDA media has proven effective in isolating and observing the morphological characteristics of fungi, such as colony color, texture, and growth rate. This medium provides adequate results in identifying microorganisms involved in the tempeh fermentation process. This research is important for maintaining the quality and safety of Bayung Lencir's signature tempeh and opens up opportunities for the development of local starter cultures that can improve quality control during the fermentation process. Molecular-based research is needed to further explore the identity of microbes and to improve the safety and competitiveness of tempeh in the global market.

Tempe is a fermented soybean product widely known in Indonesia and various countries, with Rhizopus oligosporus fungus as the main microorganism involved in the fermentation process. This study aims to observe the growth of Rhizopus oligosporus fungus isolated from tempeh using the dilution method and grown on Potato Dextrose Agar (PDA) media. The research process began with taking tempeh samples which were then subjected to serial dilutions. Next, the diluted samples were inoculated into PDA media and incubated at 37°C to facilitate fungal growth. Observations were made periodically to monitor the development of fungal colonies and the morphology formed. In the observation, it was found that Rhizopus oligosporus fungal colonies growing on PDA media were grayish-white with a distinctive filamentous hyphal structure. This indicates that PDA media strongly supports the growth of the fungus. In addition, the dilution method used in this study proved effective in separating fungal colonies, thus facilitating the morphological identification of each colony. The serial dilution method is very important in isolating microorganisms present in tempeh samples. By separating the fungal colonies from each other, researchers can observe the development of each colony more clearly and accurately. The results of this study indicate that PDA media is very suitable for supporting the growth of Rhizopus oligosporus and that the serial dilution method is an effective way to isolate this fungus from tempeh. In conclusion, this study proves that serial dilution followed by inoculation on PDA media is an effective method in observing and isolating Rhizopus oligosporus from tempeh. PDA media is able to support optimal fungal growth and allows for clear observation of the colonies and their morphology.

This study aims to develop tempeh (Rhizopus oryzae) into tempeh flour to be utilized as the main ingredient in the production of a traditional Indonesian cookie known as kastengel. Tempeh is a rich source of plant-based protein and dietary fiber, yet its application in the processed food industry, particularly in dry baked goods such as cookies, remains underexplored. This innovation is expected to serve as a healthy food alternative while supporting the diversification of local food products. The research employed a Research and Development (R&D) approach, encompassing several key stages: processing tempeh into flour through slicing, drying, grinding, and sieving; formulating kastengel dough using tempeh flour as the base ingredient; and evaluating the final product through both organoleptic (sensory) testing and nutritional analysis. Organoleptic testing involved 10 panelists, including lecturers and students, who assessed the product based on color, taste, aroma, and texture. Nutritional content was analyzed at the Manado Industrial Research and Standardization Agency. The results showed that kastengel made from tempeh flour had a light brown color, a savory-sweet flavor, a distinctive yet pleasant aroma, and a crunchy texture. Laboratory tests revealed the nutritional composition of the product to include 46.12% carbohydrates, 29.82% fat, and 3.92% protein, indicating its potential as a nutritious food option. Most panelists reported a favorable response toward the product. In conclusion, tempeh flour can serve as an effective substitute for wheat flour in the production of kastengel cookies. The final product, branded as “Kastengel Eka,” demonstrates that tempeh-based food innovations can be well-accepted in terms of sensory qualities and possess promising potential as a functional, nutritious, and marketable food product.

This study aims to evaluate the financial feasibility of tempeh production using genetically modified soybeans (Genetically Modified Organisms/GMO) at the Annisa Tempe Micro, Small, and Medium Enterprise (MSME) in Kubu Raya Regency. GMO soybeans are the preferred choice for the business owner due to their stable availability and lower price compared to local soybeans. This research employs a case study approach and utilizes investment feasibility analysis methods, including Net Present Value (NPV), Internal Rate of Return (IRR), and Net Benefit-Cost Ratio (Net B/C). The results show that the business yields an NPV of IDR 779,241,805, an IRR of 20.82%, and a Net B/C of 78.92. These indicators demonstrate that the GMO-based tempeh business at Annisa Tempe MSME is highly feasible from a financial perspective. The study also identifies key challenges such as competition in traditional markets and highlights opportunities through direct distribution and stable raw material supply. These findings are expected to serve as a reference for MSME actors, academics, and policymakers in developing sustainable GMO-based local food businesses.

Small-scale industries such as tofu and tempeh factories play a significant role in the local economy but often face serious issues such as workplace accidents. This study aims to describe the working conditions and their relation to unsafe acts by workers at the XYZ tofu and tempeh factory. A descriptive qualitative approach was used through direct observation and interviews with four workers. The findings show that a hot and noisy work environment, poor ventilation, and disorganized workspace affect workers’ behavior in carrying out tasks without using proper personal protective equipment (PPE). Unsafe work practices have become a common habit due to factors such as routine behavior, limited facilities, and demands for work efficiency. The study concludes that an unsupportive work environment is directly associated with the increase in unsafe behavior. Therefore, efforts are needed to improve the working environment, including ventilation, workspace layout, and adequate provision of PPE, as well as to increase workers’ awareness of occupational health and safety through regular training and outreach. These measures are essential to foster a safe and healthy work culture in small-scale industrial settings.
