Abstract

Community service is one of the three pillars of higher education, alongside education and research, which aims to bring scientific knowledge directly to the community. This community service activity was conducted through an interactive socialization program on hydrogen bonding in DNA for students at SMA Kristen Menara Tirza. The program utilized a visual teaching aid developed by the Physics Study Program at Matana University to support understanding of abstract molecular structures such as the DNA double helix. The activity involved presentations, hands-on demonstrations, and two-way discussions using the teaching aid. Thirteen students from grade 12 participated in the session, which included pre-tests and post-tests to evaluate learning outcomes. The average test score increased from 35.38 to 55.38, indicating an improvement. Based on this result, all students agreed or strongly agreed that the teaching team mastered the material and presented it engagingly and that the activity was beneficial to their learning. This program shows that a socialization method supported by visual teaching aids significantly improves student comprehension of complex scientific concepts. It is recommended that similar programs be implemented more widely and supported with the development of digital or interactive learning tools to reach broader audiences.

Abstract

Kanker payudara adalah jenis kanker yang sering dijumpai di Indonesia. Menurut data dari WHO, pada tahun 2020 jumlah orang yang terkena kanker di Indonesia mencapai 396.914 orang, dengan jumlah kematian mencapai 234.511 orang. Sel kanker dapat bermetastasis ke tulang, sehingga salah satu cara untuk mendeteksinya adalah dengan melakukan pemeriksaan bone scan. Tujuan dari studi literatur ini adalah mengetahui akumulasi uptake lesi di tulang penderita kanker payudara. Berdasarkan hasil studi literatur, sel kanker pada penderita kanker payudara akan lebih banyak bermetastasis ke tulang belakang (spine) dengan rentang nilai 0,224 – 1,142 mCi pada dosis injeksi 2 - 5 mCi dan 12,521 mCi pada rata-rata dosis injeksi 15,449 0,871 mCi.
