“…Tahu mengandung berbagai zat yang sangat baik jika dikonsumsi untuk meningkatkan gizi. Selain itu, tahu juga memiliki rasa yang enak (Hartini et al, 2021). Tahu merupakan makanan bergizi tinggi dari Cina yang dihasilkan dari ekstrak kedelai (Zheng et al, 2020).…”

Internet-based technology has a great impact on the business world. In addition, technological developments also create great business opportunities. But on the other hand, the increase in internet users is not followed by an increase in the ability of SMEs, especially SMEs to produce tofu by Mrs. Suraye in Brani Kulon Village. The lack of knowledge of the owners of SMEs producing tofu, Mrs. Suraye in Brani Kulon Village, about digital marketing has inspired the community service team to provide assistance and use information and communication technology. Then you can practice it directly by using the Google Maps application and the Tokopedia marketplace. The method used in this service is mentoring and training SME partners in tofu production in using digital marketing for their business. The target to be achieved in this community service is the implementation of digital marketing assistance to increase sales of tofu production SMEs. The result of this service activity is an increase in the knowledge and skills of SME owners in the use of technology, especially the Google Maps application as a means of information on the location of SMEs and the use of Tokopedia accounts as a medium for online sales. The impact of digital marketing is very influential in the expansion of the marketing network so as to increase the sales of MSMEs producing Mrs. Suraye tofu.

“…The results of the LCA measurement are information to measure the Eco-efficiency index as one of the parameters in a clean production strategy. Eco-efficiency index is the environmental cost effectiveness which is determined from the comparison of net value, production costs, and Eco-costs [17], [ [18], [19]. Eco-efficiency is an indicator of the sustainability of a system in several studies.…”

A circular economy (CE) is considered capable of being a solution to reduce the use of natural resources and reduce waste without harm. A circular economy system uses products and materials at maximum value and function. Various strategies were developed for this purpose. However, these efforts often require additional energy and materials to create more valuable products. Does the increase in value-creation mean more than the energy consumption and materials to make it happen? This study conducted a study of efforts to increase wood branch waste, which is usually only used for firewood, which is processed into hanger products with an upcycle strategy. This study uses the eco-efficiency method to determine the increase in value in the economic aspect compared to the environmental impact it causes. The cost of environmental impact is calculated using a life cycle assessment with Simapro software. The findings from this study are that upcycle efforts can increase product eco-efficiency. The eco-efficiency index (EEI) of hanger products is 4.512 and the EEI of firewood is 3.816.

“…Parameters that are not following the quality standards are pH, COD, TSS, TDS, and total nitrogen [8]. However, tofu liquid waste has utilization, such as being used as an alternative medium for the growth of Chlorella vulgaris [9], and used as a biogas product with an anaerobic process [2,10,11]. Therefore, liquid waste from the tofu industry has to be monitored.…”

Field parameter measurement is usually constrained by time management, causing measurement delays and, therefore, different results between field parameters and the actual environmental conditions. Tofu liquid waste contains a low pH (3–5) and suspended, colloidal, and dissolved organics matter at high concentrations; the latter might change rapidly and also cause changes to other parameters. Tofu liquid waste from a tofu factory outlet was used in this study. The field parameters in this study included pH, total dissolved solids (TDS), and electrical conductivity (EC) by storage time variation of 15, 20, 25, and 30 minutes. The total nitrogen was analyzed by the Kjeldahl method with a storage time variation of 2, 4, 6, and 8 days. The measurement of pH found no significant difference (sig > 0.05) up to 30 minutes of storage time, while EC and TDS significantly differed within 20 minutes. The total nitrogen was stable up to the second day of storage time at a storage temperature of 4–8 °C without preservatives. In water quality monitoring, the results of water samples analysis should be as close as possible to their values in the environment. This research shows that field parameters’ results can change quickly if the sample handling and analysis time are not by procedures, especially for EC and TDS. In addition, this study also shows that without giving H2SO4, the value of total nitrogen in tofu liquid waste samples decreased significantly after the second day of storage at 4–8 °C.
