Abstract

One of the latest innovations in textile waste treatment is advanced oxidation processes (AOPs) methods using an oxidizing agent capable of producing sulfate radicals (SO4•). This study aims to determine the activity of the Mn/Carbon sphere catalyst in the oxidation process, reduce the dye content by using a combination of peroxymonosulfate (PMS) and Mn/Carbon sphere catalyst as an oxidizing agent, and determine the optimum conditions in the process of reducing dye levels in the water. A hydrothermal process carried out the catalyst synthesis process to produce black carbon from D-glucose solution, then impregnated with variations of 3% and 5% of Mn metal. The degradation of methylene blue (artificial waste) of 25mg/L (1:10 dilution) was carried out for 120 minutes with variations in the catalyst mass of 0.001, 0.002, 0.003, and 0.004g and the mass of PMS 0.01, 0.02, 0.03, and 0, 04g in 100ml sample. Mn/Carbon sphere catalyst was able to activate PMS and was able to degrade methylene blue by 88.16%. The optimum condition for reducing the methylene blue levels in the water is at a concentration of 1g/L PMS and a Mn/Carbon sphere catalyst (5% Mn metal) 0.5g/L with an efficiency of 88.16%.

Abstract

Increasing the production capacity of the business unit at the Mis Hubbullah charity house to develop and improve the business unit so that it is expected to increase income that supports the Education program at the Mis Hubbullah charity house, one of the sources of animal protein that is widely consumed by the public, easy to obtain is fish and the price is cheap, but Fish quickly undergo a process of decay, so it is necessary to preserve fish. Preservation of fish aims to reduce the water content in the fish body so that it does not provide an opportunity for bacteria to breed. Fish undergo the process of decay quickly compared to other foodstuffs. To increase sales value and income, it is necessary to give a touch of innovation so that it can add business units and attract public interest. Therefore, in this community service activity, counseling was carried out on the diversification of processed catfish meat products into practical and more quality catfish nugget products. In addition, training on making catfish nuggets was conducted. Potential targets who will be given counseling are students from the Al-Ansar Mis Hubbullah Foundation.

Abstract

In the midst of the health crisis due to the ongoing Covid-19 pandemic, traditional medicine is an alternative that can be used by the community to break the chain of transmission and maintain body immunity. Immunity is important during the Covid-19 pandemic. The better a person's immune system is to fight infection, the less likely a person is to get the disease. The community has a very important role in efforts to develop traditional health by utilizing medicinal plants. Ginger and Turmeric are types of medicinal plants that are widely used as kitchen spices, and have benefits for increasing the body's immunity. The content of cincol and zingiberen in ginger acts as an antioxidant that can improve the work of the immune system. While turmeric contains curcumin compounds which act as an antiviral. The purpose of this research is to provide skills to the people of Muara Fajar Timur Village in processing medicinal plants into herbal products that are delicious to consume, useful for increasing immunity, and have economic value. Activities are carried out by direct training methods and distribution of herbal products to the community. The result of this activity is that the community can understand and be able to make herbal medicine. The success of this activity can be seen from the responses in the form of questions and answers and discussions with the training participants, the high interest of participants in participating in the activity and the benefits derived from this activity. This shows that this activity has been successfully implemented in Muara Fajar Timur Village, Rumbai District, Pekanbaru.
