Analisis Pengaruh Material Magnet Permanent Terhadap Karakteristik Generator Sinkron Radial 18 Slot 16 Pole

Pemanfaatan potensi energi angin telah menghasilkan perkembangan pada perancangan generator magnet permanen 18 slot 16 pole. Pada perancangan generator magnet permanen 18 slot 16 pole hanya mampu menghasilkan efisiensi sebear 70%. Penelitian ini bertujuan untuk menaikkan efisiensi dari generator tersebut. Pada paper ini akan melakukan percobaan dengan memasukkan inputan material permanen magnet untuk melihat pengaruh dari material magnet permanent Ceramic Ferrite, PM12: Br 1.2 mur 1.0, Neodymium Iron Boron, dan Samarium cobalt terhadap karakteristik dan efisiensi dari generator magnet permanen 18s16p dengan mengggunakan software berbasis Finite Element Method. Hasil percobaan pada model yang menggunakan material PM12: Br 1.2 mur 1.0 menghasilkan efisiensi terbesar yaitu 91%, diikuti oleh material Neodymium Iron Boron yaitu sebesar 90%, lalu material Samarium cobalt sebesar 89%, dan Ceramic Ferrite sebesar 87%

Assessing Engagement of Adolescents and Young Adults (AYA) in HIV Research: A Multi-method Analysis of a Crowdsourcing Open Call and Typology of AYA Engagement in Sub-Saharan Africa.

Engagement of adolescents and young adults (AYA) in HIV research is increasing in many settings. We organized a crowdsourcing open call to solicit examples of how AYA have been engaged in HIV research in Africa and to develop an engagement typology. We formed a steering committee, promoted the open call, organized judging and recognized finalists. We used a multi-methods approach to identify emerging themes and measure engagement. We received 95 entries from individuals in 15 countries; 74 met the eligibility criteria. More than three-quarters of entries were from AYA (55/74, 74%). Four themes characterized AYA engagement: (1) AYA were co-creators in the HIV research process. (2) AYA were involved in community-level capacity building. (3) AYA were co-leaders in minor risk research. (4) AYA used digital methods to enhance engagement. Our open call identified diverse methods of AYA engagement, which can enhance strategies used to reach AYA in African HIV studies
