Abstract

The green synthesis of Fe3O4 nanoparticles based on natural sand as a liquid waste degrader has been conducted. Fe3O4 powder was obtained by separating natural sand using a permanent magnet through the electrocoagulation method with Mn doping and AC composite. The 5 variations of Mn doping aimed to induce ferromagnetic properties and stabilize MnxFe3-xO4 particles as methylene blue degraders, while the AC composite aimed to enhance pollutant absorption. Characterization using Fourier Transform Infrared and X-Ray Diffraction analyzed the functional groups, nanostructure, and crystal size of MnxFe3-xO4 powder, showing that increasing the molarity of Mn doping strengthened functional group bonds and stabilized particle size up to 8.389 Å. The magnetic nanocomposite powder was applied to a methylene blue solution as a model for textile liquid waste. Ultraviolet Visible Light testing revealed decreased light absorbance in the surface state region and an energy bandgap widening of 5.25 eV. The larger energy bandgap indicated a lower refractive index, indicating the clarity of the resulting liquid. COD and BOD testing supported these findings, as samples with 0.3M and 0.7M doping showed a decrease in COD from 299.82 mg/L to 287.27 mg/L and a decrease in BOD from 127.08 mg/L to 115.16 mg/L. The characterization results demonstrated that the magnetic nanocomposite powder MnxFe3-xO4/AC effectively served as a methylene blue degrader. It transformed the sample colour into a clearer state and reduced pollutant levels, complying with the wastewater quality standard. This research offers an environmentally friendly solution for a cost-effective and efficient methylene blue degrader.

Abstract

One type of marine ornamental fish that can be developed through cultivation is betok Ambon fish. Cultivation of this fish is quite profitable, and easy to maintain. To maintain the sustainability and sustainability of Betok Ambon fish farming, one way to take is to understand and know the growth and reproduction aspects of this type of fish through the provision of inferent hormones appropriately. Review article This aims to reveal the role of the inferent hormone on the aspects of reproduction and growth of Betok Ambon fish. Reproduction is the reproduction process in living things including Betok Ambon fish. The number of eggs produced by Betok Ambon fish varies between 900 and 3,500. Inferent hormone is one type of reproductive hormone that functions to spur and accelerate the level of gonad maturity in animals including fish. The determination of the inferent hormone dosage is based on the determination of the inferent dose in fish, generally around 10 mg - 80 mg or about 0.1 ml - 0.8 ml. Generally, fish that are given inferent hormone at a dose of 40-60 mg / l can increase the gonad maturity index by 25%, in betok Ambon fish by 30%. Inferent hormone doses around 20-40 mg can increase the growth and survival of ambon betok fish.

Abstract

The home industry for coconut jam and VCO in Moiso village does not yet have a PIRT number so that the marketing of these two products is still limited. This is because they do not have knowledge related to PIRT management. Assistance is needed from parties who understand this. In the management of PIRT, there are stages of food safety education. Food safety education was attended by the home industry coordinator and his team. In this counseling material was presented on food safety, food packaging and labeling, the application of CPPB and food processing technology. There are pre-test and post-test at the beginning and end of the activity to assess participants' mastery before and after being given food safety education. The results of the counseling show that home industries are entitled to PIRT with several improvements to level 1 or 2. Several things need to be improved, including improving the position of the production site so that it is not close to the WC, storage areas for materials and tools to be more organized, sources of clean water for more production guaranteed continuity. Moiso's home industry has received a Food Safety certificate from the West Halmahera Health Office.
