Early childhood represents a golden period that is vital for the development of all aspects of a child’s abilities, particularly language skills. Speaking ability plays a central role as it serves as a child’s primary means of communication and social interaction. However, not all children achieve speech milestones appropriate for their age. Speech delays can negatively affect social, emotional, and academic growth if not identified early. This study aims to identify speech delays in early childhood through classroom interactions and to analyze the role of teachers in early detection and stimulation of language skills. Using a descriptive qualitative approach, the study involved ten children aged 4–6 years at Siti Khadijah Kindergarten. Data were collected through observation, interviews, and documentation, and analyzed using the Miles and Huberman interactive model comprising data reduction, data display, and conclusion drawing. Findings revealed that two children showed signs of speech delay, characterized by limited vocabulary, unclear pronunciation, and difficulty forming simple sentences. The main contributing factors were a lack of verbal stimulation at home and excessive gadget use, which reduced direct communication. Activities such as circle time, role-playing, and storytelling were found effective for detecting and stimulating speech development. Teachers play a crucial role as early detection agents, working collaboratively with parents to ensure continuous stimulation at home. Strengthening teachers’ capacity to observe, identify, and support children with speech delays is essential for promoting optimal language development.

This study was conducted to isolate and identify lactic acid bacteria (LAB) present in nilem fish bekasam, a traditional fermented product from Muaro Jambi. A 1-gram sample of bekasam, which had been fermented for 7 days, was used as the test material. The sample was diluted in stages to 10⁻⁶ and then plated on Nutrient Agar medium using the pour plate method. The incubation was carried out at 37°C for 24-48 hours. Upon observation, bacterial colonies with characteristics typical of lactic acid bacteria were noted. These colonies were small in size, round in shape, white to cream in color, had smooth surfaces, and flat edges. Gram staining tests revealed that most isolates were Gram-positive bacteria with rod or oval shapes, which is consistent with the characteristics of the Lactobacillus genus. Further tests showed that these bacteria were catalase-negative, non-spore-forming, and produced lactic acid as their primary metabolic product. These findings suggest that lactic acid bacteria, particularly the Lactobacillus species, dominate the microbial population in the fermentation process of nilem fish bekasam. The study highlights the significant role of LAB, especially Lactobacillus, in the fermentation process, contributing to the unique flavors, texture, and preservation properties of this traditional fermented product. This research emphasizes the importance of LAB in traditional food fermentation processes.

Tempoyak is a traditional fermented paste made from durian in Indonesia, favored by the Malay ethnic group. While tempoyak holds a unique and significant place in Indonesia's rich culinary diversity, there is a notable gap in research about it compared to other fermented foods such as kimchi. More investigation is essential to grasp the microbial composition, interactions, and possible health advantages of tempoyak, which may offer benefits like boosting the immune system, reducing cholesterol levels, exhibiting probiotic qualities, preservation, and possessing antibacterial effects. Researchers could also discover vital insights regarding the history, cultural significance, production methods, microbiological issues, nutritional aspects, and future prospects of local foods like tempoyak. This research intends to examine and study tempoyak as a traditional fermented food through comprehensive literature review and data from earlier investigations. Tempoyak has a strong connection to Malay cultural identity, regardless of its production location. As a key element of the daily practices of the Malay people in Indonesia, tempoyak is typically featured at cultural events, weddings, or large gatherings. This cultural importance sets Indonesian tempoyak apart from its Malaysian counterpart. The process of making tempoyak involves mashing the durian flesh, mixing in salt, and letting the combined mixture ferment in a sealed container at room temperature for 4 to 7 days. The microbial population in tempoyak can differ but mainly includes Lactobacillus species, particularly Lactobacillus plantarum. Proximate analysis is an effective approach to evaluate the nutritional makeup of tempoyak. Differences in nutrient levels may arise from the various types of durian, salt elements, sterilization periods, temperatures, and length of fermentation. Potential research opportunities could explore tempoyak’s role in fostering sustainable food practices, additional health benefits from its consumption, and the development of innovative products based on tempoyak. The aim of this study will enhance the field and aid in safeguarding and promoting the culinary heritage of the Malay community.

Various recent studies have shown that natural active compounds contained in traditional and fermented plants play a crucial role in supporting human health. These compounds include flavonoids, polyphenols, tannins, saponins, alkaloids, organic acids, probiotics, and other phenolic compounds. Detection of these compounds is usually carried out through specific chemical reactions that allow researchers to more precisely identify the bioactive components. Their biological activities are diverse, including antioxidant, antibacterial, anti-inflammatory, and antimicrobial properties, which work to protect the body from cell damage and infection. Natural compounds are considered promising agents for disease prevention and health promotion due to their broad biological activities. The fermentation process has been shown to increase the content of bioactive compounds while lowering the pH of the medium, creating conditions unfavorable for the growth of pathogenic bacteria. Furthermore, probiotics that develop during fermentation play a role in maintaining the balance of the gut microbiota, strengthening the immune system, and improving digestive health. Fermented products are widely recognized as functional foods because they contain beneficial probiotics and enhanced bioactive compounds. These naturally derived products, rich in secondary metabolites, have also been shown to have significant physiological effects, such as lowering cholesterol levels, controlling blood sugar, and maintaining stable blood pressure. This makes natural ingredients and fermented products not only sources of nutrition but also have great potential for development as functional foods and traditional herbal medicines. This highlights the importance of integrating traditional knowledge with modern scientific approaches in developing functional foods and herbal medicines. Therefore, research on natural bioactive compounds and the role of fermentation in enhancing their effectiveness is highly relevant to supporting sustainable public health.

The production process of graphite glass at ABC faces challenges in the form of waste that has an impact on low operational efficiency. Waste in production activities can affect the quality, cost, and timeliness of product completion. This study aims to identify the most dominant types of waste and provide relevant improvement recommendations to improve production efficiency. The method used is Value Stream Mapping (VSM), a visual approach that maps the flow of the production process from raw materials to final products. The research stage is carried out through direct observation on the production floor, time study, interviews with employees, and documentation of production activities. The results of the analysis show that the most dominant form of waste is overprocessing, which is a repetitive activity that does not add value to the product. This causes longer production cycle times and reduces the effectiveness of resource use. To overcome this, this study provides several recommendations, including: combining production processes that have similar functions, redesigning workflows to make them more concise, and eliminating activities that do not provide added value. The implementation of this improvement has proven to be effective by increasing the Process Cycle Efficiency (PCE) value from 45% to 67%. The increase in PCE reflects that the production process has become more efficient, the workflow is smoother, and the rate of waste has decreased significantly. In addition, the results of this study also confirm that the application of the VSM method can be a strategic solution in identifying sources of inefficiency, designing continuous improvements, and increasing the competitiveness of companies. Thus, the company is expected to continue to evaluate, control, innovate, and improve technology so that efficiency achievements can be maintained, expanded, and improved consistently and sustainably in the future.
