Abstract

The Micro, Small, and Medium Enterprises (MSMEs) industry in Kampung Batik Gedong, Semarang, has made a significant contribution to the local economy through the production of Semarang's signature batik. However, this production activity produces liquid waste containing synthetic dyes and heavy metals, which have a negative impact on the environment. The lack of effective waste processing technology and the low knowledge and skills of MSMEs in waste management are major challenges that require immediate solutions. This community service program aims to increase the capacity of MSMEs in managing liquid waste sustainably through the application of electrolysis technology and integrated training. The activities are carried out in five stages: preparation, socialization, application, monitoring, and evaluation. The data collection method involves measuring the level of knowledge using pretests and posttests, as well as assessing skills through direct assessments by the service team. The target of the program's success is to increase the understanding of MSMEs implementer by 80% and skills by 75% after training. Electrolysis technology is applied to reduce the concentration of dyes and heavy metals in liquid waste, while training is provided to improve the understanding and technical skills of MSMEs implementer. The results of this program are expected to include reducing the level of liquid waste pollution, increasing the technical capacity of MSMEs implementer, and increasing awareness of the importance of environmental sustainability. Thus, this program supports environmental conservation, the sustainability of the batik industry, and the achievement of the Sustainable Development Goals (SDGs), especially SDGs 6 (Clean Water and Sanitation), SDGs 12 (Responsible Consumption and Production), SDGs 13 (Action on Climate Change), and SDGs 14 (Life Below Water).

Abstract

Water is essential to human life because it is the main foundation for survival. The service aims to collaborate with Gemulak Sayung Village, Demak Regency, and Jawa Tengah coastal communities to obtain a decent drinking water supply from rainwater treatment using electrolysis science and technology. The stages of service implementation were carried out through observation, training in making simple electrolysis equipment, monitoring, and evaluation. On observation, the problem was obtained: water availability is still minimal for consumption. Implement training in making electrolysis equipment that can be applied in their homes. Monitoring and evaluation are carried out to ensure the sustainability of the service implementation. The service results showed that participants learned about the benefits of rainwater and simple processing technology using electrolysis to produce electrolyzed water in alkaline and acidic water. 95% of participants wanted the service process to be continued because it benefited the Gemulak Village, Sayung, and Demak communities.

Abstract

Water is an essential resource, crucial for human survival and well-being. In coastal areas like Sayung District, Demak Regency, Central Java, accessing clean drinking water is a significant challenge. This problem is made worse by environmental issues such as tidal flooding, known locally as "rob," which causes the groundwater to become salty and undrinkable. To address this urgent issue, the UNNES (Universitas Negeri Semarang) community service team has launched a project aimed at using rainwater as a source of safe drinking water. The project follows several key steps: first, assessing the current situation to understand the needs and resources of the community; second, training local residents on how to use electrolysis to convert rainwater into potable water; and third, evaluating the effectiveness of the training and the results achieved. The outcomes of this project have been highly positive. The community has gained valuable knowledge about rainwater treatment technologies, developed skills in building electrolysis equipment, and successfully produced fresh water from rainwater. This initiative not only helps to meet the immediate water needs of the community but also provides them with a sustainable solution for their future water needs.

Abstract

Low selling prices of fresh milk and the rejection of substandard milk by the Milk Processing Industry have reduced the income of dairy groups in Gunungpati, Semarang, and caused environmental problems due to milk disposal. This community service program aimed to increase the economic value of fresh milk through diversification into yogurt products. The program involved entrepreneurship motivation, assembly of a milk pasteurization unit, provision of a yogurt incubator, and hands-on yogurt production training for 20 members of a dairy processing group. The activity emphasized appropriate technology application and skill development to enable independent household-scale production. Results showed improved technical competence in yogurt processing, increased entrepreneurial motivation, and initial product trials for market testing. Fresh milk diversification into yogurt provides an alternative strategy to enhance income, reduce environmental waste, and strengthen community-based dairy business sustainability.
