The increasing number of mental health disorders in various countries has created an urgent need for innovation in the diagnosis and treatment process. This problem not only impacts individuals' quality of life but also creates a significant social and economic burden. One solution that is beginning to be widely researched is the use of artificial intelligence (AI) in the field of mental health. This research used a literature review of various previous studies discussing the role, application, and impact of AI. The results of the review indicate that AI technology, particularly in the form of digital applications such as chatbots, has great potential to support the recovery process for patients with mental disorders. AI-based chatbots can provide responsive, two-way interactions, so users feel heard and receive initial emotional support. One technical approach used is Natural Language Processing (NLP), which enables the system to understand natural human language. Simultaneously, Long Short-Term Memory (LSTM) algorithms are used to analyze language patterns and detect symptoms of depression more accurately. Various studies have reported that the application of NLP and LSTM can improve the reliability of diagnoses and provide responses tailored to user needs. Furthermore, AI can provide personalized recommendations, tailor interventions to the user's condition, and monitor mental health developments in real time. This has the potential to assist mental health practitioners in making faster and more informed decisions. However, the adoption of AI among practitioners remains relatively low. Influencing factors include limited technological understanding, limited infrastructure, and debates over ethical aspects and data privacy. Therefore, while AI has significant potential to improve the quality of mental health services, regulations, ethical guidelines, and synergy between technology and healthcare professionals are needed to ensure safe and effective implementation.

This study aims to explore how users' perceptions of the chatbot on the Shopee platform influence user satisfaction and loyalty. The research employs a qualitative approach with in-depth interviews to gather users' experiences and views on their interactions with the chatbot. The findings reveal that three key factors—clarity of responses, ease of access, and relevance of information—are crucial in determining user satisfaction. Users who found the chatbot's responses clear and easily understood, along with quick access, were generally more satisfied with the service provided. However, despite achieving user satisfaction, loyalty to the platform has not been fully established. This is due to the chatbot's limitations in building emotional connections with users and its inability to handle more complex issues. While the chatbot is effective in providing automated solutions for simple problems, it lacks the empathy and personalized attention necessary when users encounter more intricate issues or require a deeper level of interaction. These findings highlight that although chatbots can enhance the efficiency of basic customer service, they cannot fully replace human interaction, particularly in customer service contexts that require emotional engagement and a deeper understanding of the user's needs. To foster stronger user loyalty, a combined approach involving both technology and human interaction is essential. The chatbot can address routine issues, while more complex matters should be referred to customer service representatives who can offer empathetic and tailored solutions. The recommendation from this study is for Shopee platform developers and sellers to strategically optimize chatbot use while maintaining human interaction that is adaptable, in order to enhance user satisfaction and loyalty.

This study aims to analyze the influence of advertising, trust, and discounts on purchasing decisions among Shopee app users, focusing on students from the Faculty of Economics and Business, Slamet Riyadi University, Surakarta as respondents. The background of this study departs from the increasing competition in e-commerce in Indonesia, which requires each platform to develop appropriate marketing strategies to attract consumers' attention and build their loyalty. The research method used was a quantitative survey involving 100 respondents selected through a convenience sampling technique, allowing researchers to quickly obtain data from relevant target groups. The collected data were then analyzed using multiple linear regression methods to test the proposed hypotheses. The results showed that consumer trust in the Shopee app has a significant influence on purchasing decisions, meaning that the higher the level of trust, the more likely consumers are to make purchases through the app. In addition, the discount factor was also proven to have a significant influence on purchasing decisions, indicating that price cuts are still an effective strategy in influencing consumer behavior, especially students. Conversely, the advertising variable did not show a significant influence on purchasing decisions, which could mean that the intensity or quality of advertising is not strong enough to drive purchasing decisions in this respondent segment. The findings of this study provide practical contributions for Shopee in designing more targeted marketing strategies, emphasizing the importance of building and maintaining consumer trust, as well as utilizing proven effective promotional strategies such as discounts. Therefore, this study not only enriches the literature on consumer behavior in the e-commerce context but also offers useful recommendations for digital business practitioners in increasing competitiveness.

In recent years, Micro, Small, and Medium Enterprises (MSMEs) have increasingly positioned themselves as one of the main pillars of the Indonesian economy, contributing significantly to employment opportunities, income distribution, and economic resilience. In the local context, Cifest Cikarang Selatan represents a dynamic marketplace where various MSMEs operate and directly interact with consumers. An interesting phenomenon emerges during holiday periods, when consumer behavior shows significant changes, especially in terms of purchasing methods and preferences between online and offline channels. This study aims to explore the transformation of consumer behavior, focusing on the comparative analysis of online and offline purchases, and to evaluate its broader implications for the sustainability and competitiveness of MSMEs operating at Cifest. The research adopts a descriptive and analytical approach, using both recent statistical data and supporting literature to provide a comprehensive understanding of the digital era’s influence on shopping patterns. The findings reveal that online purchases continue to grow rapidly due to convenience, wider product access, and promotional offers that attract customers. However, offline purchases remain relevant, particularly for consumers who value direct product inspection, immediate ownership, and social interaction within traditional marketplaces. For MSMEs, this shift presents both challenges and opportunities. Those that rely solely on conventional offline strategies risk losing competitiveness, while those able to integrate digital platforms with traditional sales methods demonstrate greater adaptability and potential for growth. Overall, this study concludes that the sustainability of MSMEs in Cifest Cikarang Selatan depends largely on their ability to embrace digital transformation without neglecting the strengths of offline interactions. By leveraging both channels strategically, MSMEs can not only survive but also thrive in the increasingly competitive market landscape shaped by evolving consumer behavior.

This community service has the main purpose of building community character through sports activities in commemoration of the Anniversary of the Republic of Indonesia (HUT RI) in Gatak Gede Hamlet. The commemoration of the Indonesian Independence Day is not just an annual ceremony, but a momentum to foster a sense of love for the homeland and strengthen social ties between citizens. The background of this activity is based on the importance of instilling character values such as sportsmanship, togetherness, discipline, and the spirit of nationalism. These values are believed to be developed effectively through enjoyable physical activities, involving all levels of society, and having a positive impact on social life. The method of implementing the activity was carried out in a healthy way which was followed by participants from various circles, ranging from children, adolescents, to adults who live in Gatak Gede Hamlet, Kateguhan, Sawit, Boyolali. Healthy walking was chosen because it is a simple sports activity that is easy to do, can reach a wide range of ages, and has great benefits both physically and socially. In addition, healthy walks are a means of joint recreation that can give rise to positive interactions between residents, thereby fostering a sense of togetherness. The goals to be achieved through this activity are to strengthen social relations, strengthen the spirit of mutual cooperation, and instill the value of togetherness in the community. Healthy walks carried out in the framework of the Indonesian Independence Day have proven to be an effective means to build positive character, foster a sense of unity, and improve physical health.

The abundant rice husk waste in Legundi Village, Ngawi Regency, has not been used optimally and has the potential to cause environmental pollution. On the other hand, rural communities, especially the PKK Women's group, need business diversification to increase family income. Responding to these challenges, this community service program is carried out with the main objectives: (1) utilizing rice husk waste into husk charcoal products with economic value as a planting medium; (2) increasing income and empowering community groups; and (3) strengthening the capacity of digitizing MSMEs through online marketing assistance. The activity was carried out with a participatory method that prioritized the active involvement of the community. There are two main approaches to program implementation. First, training on the practice of making husk charcoal uses imperfect combustion techniques that are simple and environmentally friendly. Second, assistance in the digitalization of MSMEs which includes training in creating and managing e-commerce accounts (Shopee and Tokopedia), the production of visual and narrative-based promotional content, and digital marketing strategies that are adaptive to consumer trends. The results of the activity show that the community is able to process husk waste into packaged husk charcoal products with the brand "Saji Tani" which has selling value and market potential. In addition, the PKK Women's group showed capacity building in business management and the use of digital platforms to expand marketing access. This program not only succeeds in reducing the environmental impact of agricultural waste, but also encourages the economic independence of village communities through innovations based on local potential. Thus, this activity is a model of integrated community empowerment that combines environmental, economic, and digital technology aspects in a sustainable manner.

Schools are not only institutions for the transfer of knowledge but also environments that play a crucial role in shaping students’ behavior and instilling positive habits, one of which is environmental care. One form of environmental concern that can be cultivated from an early age is the discipline of disposing of waste properly. However, SD Negeri Jambewangi, located in Dusun Pesantren, has not yet fully implemented effective waste sorting practices. Waste disposal is still carried out without distinguishing between organic and inorganic waste, which may have negative impacts on the school environment. To address this issue, community service activities were carried out by KKN students from Universitas Tidar through outreach programs and the distribution of sorted waste bins. The socialization activity applied the Extend Parallel Process Model (EPPM) communication strategy using a Severity Model approach, which emphasized the dangers and consequences of improper waste management practices. During the sessions, students were encouraged to discuss and identify various types of waste, as well as the potential environmental and health impacts associated with them. Direct practice was also provided by encouraging students to actively participate in sorting waste before disposal into the designated bins. The implementation of this program showed a positive impact, as students demonstrated an increased understanding of waste management and began to practice sorting waste more consistently. The provision of separate bins for organic and inorganic waste further facilitated this new habit. It is expected that the discipline of sorting and properly disposing of waste will continue to be applied by students, teachers, and the entire school community. Such continuous practices can foster collective awareness, contribute to maintaining environmental cleanliness, and provide long-term benefits not only for the school but also for the surrounding community.

Breakfast is an important habit that plays a major role in meeting children's energy and nutritional needs. The energy obtained from breakfast is essential for daily activities, including learning and playing, enabling children to achieve optimal performance both physically and cognitively. Furthermore, breakfast habits also contribute to children's nutritional status, reflecting the balance between nutritional intake and needs. However, the reality shows that in Indonesia, approximately 40% of children still do not have breakfast before going to school, potentially affecting their nutritional status. This study aims to determine the relationship between breakfast habits and the nutritional status of students at Muhammadiyah Kayen Elementary School. The study used a quantitative approach with a cross-sectional design and utilized primary data. The study population was all 225 students in grades I to IV. Of these, 112 students were selected through a purposive sampling technique. Data were collected using a questionnaire to explore breakfast habits and anthropometric measurements of height and weight to determine nutritional status. Data analysis was performed using the Fisher exact test. The results showed a p-value of 0.742 (p > 0.05), indicating no significant relationship between breakfast habits and students' nutritional status. A total of 79.5% of students had good breakfast habits, while 20.5% were classified as adequate. Meanwhile, the students' nutritional status consisted of good nutrition (57.1%), overnutrition (19.7%), obesity (11.6%), malnutrition (8%), and undernutrition (3.6%). Thus, it can be concluded that breakfast habits are not significantly related to the nutritional status of students at the school.  

The development of digital technology has provided many conveniences, especially in terms of access to information, communication, and financial services. However, behind these benefits there are great risks, one of which is the misuse of personal data that is rampant through the practice of illegal online loans (pinjol). This phenomenon is a serious threat to society, especially students, who are often targeted due to the lack of digital literacy and lack of awareness about the importance of personal data protection. Illegal loans not only cause financial losses, but also have an impact on psychological and social pressure. This Community Service activity was carried out at STISIPOL Silas Papare Jayapura with the main goal of providing legal and practical education regarding personal data protection as well as preventing illegal loan trapping. Activity methods include interactive legal counseling, group discussions, and case study simulations tailored to student experience. With a participatory approach, participants are encouraged to actively ask, analyze, and find solutions to problems they may face. The results of the activity showed a significant increase in student knowledge about the basic concept of data security, signs of illegal loans, and preventive measures that can be taken. Participants also showed a higher critical awareness of the importance of maintaining the confidentiality of personal information, including the wise use of digital media. In addition, case study simulations are able to strengthen students' practical skills in identifying potential risks and strategies to deal with the threat of illegal lending in their surrounding environment.

Gunungsari Village, Windusari District, is one of the areas facing quite serious challenges in efforts to develop basic literacy in school-age children. The main problems faced are low interest in reading, limited access to adequate reading materials, and learning methods that are still conventional. These conditions have implications for many children who are not able to read and write fluently despite having received an elementary school education. In response to this situation, the community service team took the initiative to implement a literacy program that uses an interactive learning approach through the development of a literacy park. This program is not only designed to be a learning platform, but also to create a learning atmosphere that is fun, contextual, and involves the active participation of children. Various activities are implemented, including storytelling, the provision of a reading corner, educational games such as math games, vocabulary quizzes, and the provision of simple rewards to maintain high learning motivation. This program activities are carried out periodically with the involvement of the school, the surrounding community, and also the village government, so that its sustainability has the support of various parties. The results of the implementation show a significant increase in children's literacy skills. Not only are they reading more fluently, but they are also better able to comprehend story content and write simple ideas. Furthermore, the children appear more confident in expressing themselves, are more active in every learning activity, and are beginning to demonstrate positive reading habits. A culture of literacy is also slowly growing through the existence of child-friendly and inclusive literacy parks. This proves that a fun, community-based literacy approach is highly relevant in rural areas with limited resources and can be a simple yet impactful means of educational transformation for children's futures.

The hope is that they will grow into individuals with integrity, responsibility, and concern for others.  

This community service program was implemented to address the needs of farmers in Kalicaah Village, Tanjung Jaya Village, Panimbang District, for an affordable, simple, and user-friendly fertilizing tool. Traditionally, the application of solid fertilizer has been done manually, which not only leads to inefficiency but also significantly increases the physical workload of farmers. To overcome this issue, the program team designed a solid fertilizer spreader using appropriate technology, constructed from recycled materials such as PVC pipes and used water gallons. This innovation was aimed at creating a sustainable, low-cost solution for the local agricultural community. The program’s implementation involved several key activities, including identifying the farmers' challenges, conducting assembly training sessions, demonstrating the tool’s use, and running direct field trials in local farms. The results showed that the use of the newly developed fertilizer spreader led to a 45% reduction in the time spent applying fertilizer, which directly contributed to more efficient farming practices. Additionally, there was a significant reduction in physical complaints, particularly lower back pain, which had been a common issue due to the manual labor involved in fertilizing. The tool proved to be easy to construct, requiring minimal technical knowledge, and the farmers were able to adopt the technology independently. The high rate of adoption among farmers further emphasizes the tool’s potential for widespread use. The success of this program also suggests that this simple, affordable technology could be replicated in other agricultural regions, benefiting more communities by improving work efficiency, reducing physical strain, and fostering a sustainable approach to farming practices.

UD. Indokarya Brass is a company engaged in the brass handicraft industry with its main products being door handles and bells. The main raw materials used in the production process include brass, copper, tin, and aluminum, which are obtained from suppliers both within and outside the city. On average, raw materials are received weekly with quantities of 50–100 kg of brass, 7–10 kg of copper, 10–15 kg of tin, and 3–5 kg of aluminum. In addition, the company also uses additional materials in the form of thinner and epoxy purchased from nearby hardware stores with less frequent purchases, namely 5–10 liters of thinner every month and around 5 kg of epoxy every two months. To date, the company has not had a structured policy for procurement and control of raw material inventory. This condition results in excess inventory of several types of raw materials which actually incurs high costs, both in terms of storage costs and warehouse maintenance costs. This excess inventory ultimately has an impact on reduced efficiency and decreased company profits. This study was conducted to analyze the existing inventory system and compare the company's current policy with a proposed method for more optimal inventory control. The calculation results show that the proposed method is able to provide significant inventory cost savings, namely 83.25% in brass raw materials, 15.28% in copper, 14.6% in tin, 43.37% in aluminum, 4.66% in epoxy, 4.2% in thinner, and 40.7% in other raw materials. Thus, the implementation of the right inventory control method can improve operational efficiency and help companies reduce cost burdens, so that profits can be more optimal.

Worm infestation due to Soil-Transmitted Helminths (STH) infection remains a public health problem, especially among elementary school children who frequently interact with contaminated soil. This condition is a major concern because it can cause long-term health problems, particularly in terms of physical growth and development of children. This study aims to identify the presence of STH worm eggs and larvae in soil and fecal samples of children in Bekoso Village, Pasir Belengkong District, Paser Regency, East Kalimantan. This study used a descriptive approach with a cross-sectional design. The samples used consisted of 23 soil points taken from oil palm plantations with sandy and loose soil criteria, as well as 16 fecal samples from elementary school children. Fecal examination was carried out using the Kato-Katz method to detect worm eggs, while the soil was examined using the Baermann technique to detect worm larvae. The results showed that 25% of children's fecal samples were infected with worm eggs, with 12.5% containing hookworm eggs, 12.5% Taenia sp. eggs, and 6.25% Ascaris lumbricoides eggs. In soil samples, 60.87% tested positive for Strongyloides stercoralis larvae and 26.09% tested positive for Ascaris lumbricoides eggs. These findings indicate a high risk of STH infection in children in the area. Environmental factors such as soil moisture, soil texture suitable for worm breeding, and poor personal hygiene practices are suspected to be the main causes of the spread of infection. This study emphasizes the importance of education on clean and healthy living behaviors (PHBS) and improving environmental sanitation to reduce cases of worm infection, especially in endemic areas such as Bekoso Village. More comprehensive prevention efforts are urgently needed to address this problem and improve public health, especially among elementary school children.

Data were collected using questionnaires, observation, interviews, and documentation. The analysis techniques include validity and reliability tests, classical assumption tests, multiple linear regression, t-test, and F-test. The findings show that both training and human resource development have a significant and positive impact on employee performance. Training improves employee skills, while development efforts enhance competencies to meet organizational demands. The study suggests that structured training and development programs should be optimized to improve public service performance.

Background : Children with Autism Spectrum Disorder (ASD) generally experience difficulties in communication skills, both verbal and nonverbal. These difficulties impact social interaction and academic development in children. Objective: This study aims to determine the effectiveness of Applied Behaviour Analysis (ABA) in improving communication skills in children with Autism Spectrum Disorder (ASD). Method : Three children aged 4, 5, and 6 years, diagnosed with moderate-level ASD using the Childhood Autism Rating Scale (CARS), participated in the study. A six-month ABA intervention was administered individually, incorporating Discrete Trial Training (DTT), prompting, and positive reinforcement. Communication outcomes were measured pre- and post-intervention using the Vineland Adaptive Behavior Scales (VABS), supported by direct observation and parent interviews. Data were triangulated across multiple sources. Result : Participant A1, who participated for 4 years, showed modest improvements across all categories. For example, their RSP score increased from 45 (RSPe) to 60 (RSPo), while TTL scores rose from 30 (TTLPe) to 42 (TTLPo). Participant A2, with 5 years of engagement, exhibited more pronounced progress. Their RSP scores improved from 52 to 70, and TTL scores increased from 40 to 55, reflecting consistent gains across emotional expression and overall performance. Participant A3, who had the longest participation (6 years), achieved the highest scores in all areas. Their RSP scores increased from 60 to 78, EXPe to EXPo from 58 to 76, and TTL scores from 50 to 68, indicating strong developmental outcomes over time. Conclussion : The results of the VABS and CARS before and after the intervention showed significant improvement. These findings indicate that ABA therapy is effective in developing communication skills and reducing the severity of symptoms in children with ASD. Result : The implications of these results reinforce the importance of early behavioural-based intervention in therapy programmes for children with autism.

This study aims to analyze the sentiment of customer reviews of the Grand Jatra Hotel Pekanbaru on the Google Review platform using the Naïve Bayes algorithm. Social media and online review platforms are increasingly becoming the primary source of information for potential customers in making purchasing decisions, particularly in the hospitality sector. Therefore, sentiment analysis of customer reviews is crucial for understanding consumer perceptions and providing strategic input for hotels in improving service quality. The research data was collected using web scraping techniques to obtain publicly available customer reviews. The obtained data was then processed through text preprocessing stages including case folding, tokenizing, normalization, stopword removal, and stemming. The Term Frequency-Inverse Document Frequency (TF-IDF) method was then used to weight each word, so that more relevant words have a greater influence in the classification process. The sentiment classification process was carried out into two main categories, namely positive and negative. The Naïve Bayes model was trained using training data and then tested with test data to measure the algorithm's performance in classifying sentiment. The evaluation results show that the model built is able to achieve an accuracy level of 98%, with a precision value of 97% and a recall of 100% in the positive class, and 92% in the negative class. These findings confirm that the Naïve Bayes algorithm can be effectively used in analyzing customer sentiment towards hotel services and facilities. Practically, the results of this study are expected to provide insight for the management of Grand Jatra Hotel Pekanbaru in understanding customer perceptions, identifying service strengths and weaknesses, and formulating more targeted marketing strategies. In addition, this study can also be a reference for the development of similar studies in the hotel industry and other service sectors.

Advances in digital technology in the financial sector have encouraged Micro, Small, and Medium Enterprises (MSMEs) to shift from cash payment systems to non-cash payments through QRIS (Quick Response Code Indonesian Standard) as an effort to increase efficiency and modernize transactions. This research is motivated by the low level of QRIS adoption among MSMEs in Junti Village, Jawilan District, Serang Regency, Banten, most of which still rely on cash-based transactions. The purpose of this research is to analyze the implementation of QRIS by MSMEs, identify the obstacles faced, and assess the impact of the system's implementation on daily business activities. Data were collected through field observations, interviews with MSME actors, and supporting documentation, and this research was conducted in Junti Village in July 2025. The results revealed that some MSMEs that have adopted QRIS experienced benefits in the form of ease in conducting transactions, increased efficiency, and a more professional business image. These findings also confirm that the use of QRIS contributes to the acceleration of digital transformation in the MSME sector, although not yet fully optimal. The main obstacles encountered were limited access and the quality of internet infrastructure, which is still uneven, making it difficult for some business actors to utilize QRIS optimally. Based on these results, the study recommends the importance of increasing the intensity of socialization and training on QRIS use, as well as the need for ongoing support from local governments and financial institutions so that MSMEs can adapt more quickly and comprehensively to changes in digital technology, so that MSME digital transformation can take place effectively, inclusively, and sustainably. This study recommends the need for increased socialization, training, and support from financial institutions and local governments to encourage sustainable digital transformation of MSMEs.

Corruption is an extraordinary crime that damages the foundation of the state. In the context of Government Procurement of Goods/Services (PBJP), corrupt behavior still occurs even though it has been regulated through Presidential Regulation Number 12 of 2021 as an amendment to Presidential Regulation Number 16 of 2018. The implementation of the PBJP policy is considered to be not able to effectively suppress the potential for corruption, so other variables are needed that affect the effectiveness of the policy. This study aims to analyze the direct and indirect influence of the leadership style and quality of human resources (HR) of the state civil apparatus on the potential for corruption through the implementation of PBJP policies. The research method used is quantitative with the Partial Least Squares - Structural Equation Modelling (PLS-SEM) approach, which aims to test the relationship between latent variables and confirm the influence of leadership style and quality of human resources on potential corruption through the effectiveness of PBJP implementation. The research population includes elements of PBJP policy implementation within the Corruption Eradication Commission (KPK), including PPK, procurement officials, UKPBJ working groups, and goods/service providers. The sample was determined by purposive random sampling, consisting of internal and external implementers of PBJP at the KPK with a budget value of more than IDR 1 billion in the 2024 fiscal year. The results of the study show that leadership style has a positive effect on the implementation of PBJP and directly reduces the potential for corruption. The quality of ASN human resources has a positive effect on the implementation of PBJP, but it has a double effect on the potential for corruption. The mediation test showed that the implementation of PBJP mediated part of the influence of leadership style and human resource quality on potential corruption, with the direction of influence changing from positive to negative. These findings confirm the importance of the effectiveness of the implementation of PBJP policies in suppressing the potential for corruption within the KPK.

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.
