Abstract

Abstract: Material selection and innovative and creative designs are needed as a medium for reducing production costs by changing the design of a product but still paying attention to the safety of its users. The problem that occurs in the surrounding community is the lack of public knowledge about the selection of materials that can risk accidents that will be experienced by users which can be caused by the material not being strong enough to support the load it gets. Innovative and creative design aims to reduce the mass of the material but still refers to user safety. Inappropriate design can increase the risk of accidents and wasted costs in the production process. The method used in this community service is a material selection workshop and an introduction to machine design using solidworks software. Therefore, this community service will greatly help the community in the Karang-tempel Village, East Semarang District, increase their insight into the selection of materials and innovative designs as an increase in the quality of production and ensure the safety of users.          Keywords: creative; desain; inovative; material selection; workshop Abstrak: Pemilihan material dan desain yang inovatif dan kreatif sangat diperlukan sebagai media pengurangan biaya produksi dengan merubah rancangan suatu produk akan tetapi tetap memperhatikan keselamatan dari penggunanya. Permasalahan yang terjadi di masyarakat sekitar akan kurangnya pengetahuan masyarakat tentang pemilihan material yang dapat berisiko akan terjadinya kecelakaan yang akan dialami pengguna yang dapat disebabkan oleh material tidak cukup kuat untuk menopang beban yang didapatkannya. Desain yang inovatif dan kreatif bertujuan sebagai pengurangan massa dari material akan tetapi tetap merujuk kepada keselamatan pengguna. Desain yang tidak sesuai dapat meningkatkan risiko kecelakaan dan pemborosan biaya pada proses produksi. Metode yang digunakan pada pengabdian masyarakat ini adalah workshop pemilihan material dan pengenalan rancang bangun mesin menggunakan software solidworks. Oleh karena itu pengabdian kepada masyarakat ini akan sangat membantu mas-yarakat di lingkungan kelurahan Karang-tempel, kecamatan Semarang Timur untuk menambah     wawasannya terhadap pemilihan material dan desain yang inovatif sebagai peningkatan kualitas hasil produksi dan menjamin keselamatan dari pengguna.Kata kunci: desain; inovatif; kreatif; pemilihan material; workshop

Abstract

Drying is the process of removing water or separating a relatively small amount of water from a material using heat energy. One method of drying is through oven processing, which aims to reduce the moisture content in materials using an oven. This study aims to analyze the airflow rate in an oven using Computational Fluid Dynamics (CFD) simulation and to examine the effect of temperature variations on airflow rate using CFD simulation. The research method employed is experimental, with data collection techniques including descriptive analysis, involving experiments, simulation results, and documentation. The study found that the simulated airflow rate using Ansys R2 2020 varied with different temperatures. At 70℃, the air velocity ranged from 1.108 m/s to 4.432 m/s, while at 75℃, it ranged from 1.882 m/s to 11.29 m/s. Turbulence occurred at both temperatures, and higher temperatures resulted in faster airflow rates due to reduced air resistance. At 75℃, the crackers achieved optimal dryness, with a weight reduction of 95%. High temperatures can reduce air density which can increase air flow speed due to a decrease in resistance experienced by the air.
