Abstract

The rare earth element (REE) is not a free metal element or an individual pure mineral, generally in the form of compounds. To obtain rare earth element is done by extraction that requires modern technology with expensive costs. The use of REE is very important for the development of industry and modern technology. Seeing the potential and rapidly developing technology, the Rare Earth Metal in developed countries is currently being used as a mixture of materials in the manufacture of weapons. This journal will discuss the use of rare earth element for the F-35 Lightning II fighter. REE used in F-35 is a mixture for composite Graphite/Epoxy and Graphite/Bismaleimide, as elements Rhenium, Samarium, and Tantalum. This compost is used on the fuselage structure as an example for the Fuselage Center. The results of these alloys can increase aircraft performance, which is resistant to high temperatures, resistant to high pressure, and cannot be detected by radar (stealth). But also before being applied it needs accurate analysis of the negative impacts if the composites are implemented

Abstract

Iron sand is the main ingredient of making iron pellets. Iron pellets are the main ingredient of steel plates. Iron pellets for steel industry in Indonesia are still imported from Sweden, Brazil, and Chille.  The reason for import that Ferro content in the local production of iron pellets is less than 60% (Fe 60%).  The effect that Ferro (Fe) quality in the local iron sand as the main ingredient of iron pellets is assumed to be less than 60%. This issue should prove that the assumption is incorrect. The research aims to prove that the level of Ferro contained in the local iron sand is more than or equal to 60%. The research also proves that local iron sand can be finished with quality iron pellets. The results showed that Ferro levels contained in local iron sand ranged from 71.03% to 73.05%, compared to Ferro levels outside of iron sand ranging from 61.00% to 68.90%. Based on the results of a comparison of Ferro rates on iron sand, Ferro content on local iron sand is greater than the iron sand content of Ferro abroad. Then it can be concluded that the level of Ferro in local iron sand is less than 60% is not proven, hence the reason steel industry uses imported iron pellets with the reason of Fe level local iron sand is less than 60%, not based on the results of scientific research.

Abstract

MSMEs have a strategic role in national economic development, but still face various challenges, especially in terms of legality and improving product quality. One aspect of legality that is important, but has not been widely accessed by MSMEs in Padaasih Village, West Bandung Regency, is halal certification. In fact, halal certification not only guarantees religious aspects, but also increases consumer confidence and product competitiveness in domestic and international markets. This community service activity aims to increase the understanding and capacity of MSME actors in the halal certification process and strengthening product quality through an educational and participatory approach. The activity was carried out at PKBM Bina Bangsa Berkarakter as a strategic local partner, involving 25 MSME players engaged in the food and beverage sector. Implementation methods include socialisation, simulation training for applying for halal certification, product quality training, and interactive discussions. The results of the activity showed a significant increase in participants' understanding of the procedures and benefits of halal certification. In addition, participants also gained basic skills in improving packaging and product quality according to food safety standards. The final evaluation showed that 92% of participants stated that the activity was very useful and encouraged their interest in taking care of product legality independently. This activity strengthens the role of PKBM as a community learning centre that can bridge MSMEs in accessing halal certification information and services.

Abstract

The business climate has improved significantly since the COVID-19 pandemic. Community-based businesses, including MSMEs, both in urban and rural areas, have grown significantly. The Indonesian government has also devoted significant attention to MSMEs by establishing a Ministry of MSMEs at the central level and relevant MSME agencies at the provincial and district/city levels. The development of MSMEs in Garut Regency and Malangbong District has been met with great enthusiasm by the community. Traditional Garut MSME products, already in thriving form, are now expanding with improved styles, flavors, and attractive packaging. Furthermore, their quality has also improved. This improvement in quality also opens up opportunities for increased marketing of these products.
