Publisher : OJS Universitas Muhammadiyah Gresik

Gapoktan Al-Barokah of Lombok Kulon, Wonosari Subdistrict, in Bondowoso Regency has started milling organic rice using husking machine thus produced raw red rice. Raw red rice is rice grain that has its husks removed. The study established that raw red rice is actually covered by hard husk which contains Phytic Acid that could obstruct nutrition absorption to the body. Other drawbacks from raw red rice is that soaking is required before cooking, the texture of the cooked rice is hard to eat, and its nutrition is difficult to digest. These make it less favorable among society therefore it is not in a good sale so far, resulting in low revenue of the organic rice farmers. Therefore, this program was initiated to enrich the quality of red rice products through adding a step into the milling process which is milling using sugawa machine to remove the hard husks. The final product expected from the program was organic embryo red rice that is easy for cooking, soft textured cooked rice, and digestable rice in order to increase the chance of optimal nutrition absorption to the body. Among several solutions offered in the program include supplying and testing a milling machine, production training and guidance, socializing and marketing. The first solution administered was supplying and testing a Sugawa machine to mill raw rice into embryo red and brown rice. Then, it was followed by providing a Sugawa pressure cooker tool to mix derived product from the materials used such as embryo rice and bran, that is embryo porridge and bran cereal. The training conducted in the program contains guidance for applying the SOP of producing embryo rice and its derivatives. While socialization was administered specifically to the board and partners of Gapoktan Al-Barokah, village government, field trainers, and muspika (council for local government) of Wonosari aiming to achieve a collective and sustainable movement, as well as a group of patients of degenerative illnesses from Community Health Center of Wonosari. Finally, it was followed by marketing that was performed during the socialization by providing samples of embryo red rice, embryo brown rice, and its derivatives. The embryo rice was packaged in a 1kg-vacuum bag, labelled with Botanik Beras Embrio Merah and Botanik Beras Embrio Coklat and thereby distributed to nearby stores around Wonosari subdistrict area.

The sustainability of livestock quality is greatly influenced by animal feed. Precision livestock feed products are very important for improving product quality and safety, improving the health and welfare of livestock, as well as reducing the environmental impact of livestock manure by processing it into natural organic fertilizer using a symbiotic mutualism technique between the animal husbandry and agriculture sectors. It is important for farmers to know how to ferment livestock waste to increase soil fertility. This process breaks down the organic materials in livestock manure into nutrients. This is necessary so that the nutrients are more stable and easily absorbed by plants; kills a number of parasites, bad bacteria and pathogens that can inhibit the plant growth process. For this reason, the livestock manure fermentation process is carried out correctly so that the results are optimal. With this fermentation method, plants show excellent growth and development and have superior quality when compared to plants without treatment. On the other hand, the Silage method is very suitable for stabilizing animal feed stocks. Farmers can make feed without having to look for grass every day, which still maintains its nutritional quality and the results show that almost all livestock like silage or this form of fermented feed.

Microplastics are known to be composed of many chemical compounds, and there are compounds that act as hormone disruptors that can trigger insulin resistance. Children are the highest consumers of sugar-sweetened beverages in packaging (SSBs), which generally have plastic packaging. The study aimed to identify the presence of microplastics and polymer types of SSBs that are widely consumed in Indonesia, and evaluate their potential impact on health, especially the risk of diabetes mellitus in children. SSBs samples were taken from several brands in traditional and modern stores in Gresik Regency. The analysis was conducted by FT-IR test with the control variable being the water source from Beji Spring, Wonosalam. Furthermore, a literature review was conducted on the relationship between microplastics and diabetes mellitus in children. The results showed that the microplastics detected were filaments and fibers with polymers PET, PP, POM, EVOH and others. Microplastics are known to affect the performance of the pancreas so that it will cause diabetes mellitus in children. Reflecting on this condition, the government is expected to make quality standards for microplastics because of their harmful impact on the human body, especially children.
