Abstract

Proses ECAP merupakan salah satu proses perlakuan mekanik yang mampu menghasilkan butir material yang sangat halus (ultrafine grained). Baja karbon rendah dengan kandungan 0.16% C berdiameter 11mm dan panjang 65mm diberikan perlakuan mekanik melalui proses ECAP menggunakan cetakan yang memiliki sudut pada sisi dalam, θ = 1200 dan sudut sisi luar, Ψ = 70. Variabel prosesnya adalah jumlah laluan deformasi tanpa mengubah rute setiap laluannya. Dampak dari proses terhadap sampel ditinjau melalui uji kekerasan, densitas, porositas, dan metalografi. Sedangkan untuk mengetahui kekuatan sampel dilakukan dengan pendekatan persamaan Hall-Petch dimana besar butir yang terbentuk diukur menggunakan software Image-J. Hasil pengujian pada sampel menunjukkan adanya peningkatan densitas, penurunan porositas, dan penghalusan butir pada sisi sampel seiring peningkatan jumlal tahapan (laluan) deformasi yang menunjukan peningkatan kekuatan dari baja karbon rendah ST 41.

Abstract

Online motorcycle taxis are a mode of transportation that is widely used today. Online motorbike taxis are very quickly accepted by the public because of the ease of ordering and are application-based which can be easily downloaded by smartphone users on both Android and iOS systems. Thanks to online motorcycle taxis, passengers no longer need to wait on the side of the road to be picked up. In addition, passengers do not have to participate in negotiations, because the price has been determined per kilometer by the application system. The presence of online motorcycle taxis also adds jobs for the people of Indonesia.

Abstract

The main problem faced by partner communities in Muntang Village is the low knowledge of pregnant women related to nutritional fulfillment during pregnancy and the strong influence of myths that are not based on science, which has the potential to increase the risk of stunting. This service activity aims to increase the knowledge and awareness of pregnant women, PKK mothers, and posyandu cadres through the use of interactive multimedia nutrition education. The solution offered is the development and implementation of the BUNDACERDAS application as a digital-based educational media that contains material about the First 1000 Days of Life, the nutritional needs of pregnant women, stunting prevention, and interactive quiz features. The method used is a participatory approach through the stages of observation, socialization, training, implementation, and evaluation. The results of the activity showed an increase in participants' knowledge by an average of 31 percent based on a comparison of pre-test and post-test in 50 participants. In addition, the participants' satisfaction level achieved an average score of 4.6 out of a scale of 5 which was included in the very satisfied category. Thus, this activity has proven to be effective in increasing community nutrition literacy and has the potential to be developed sustainably as a technology-based health education media.
