Abstract

Wortel (Daucus carota L.) merupakan sayuran bernutrisi tinggi yang mudah rusak akibat kandungan airnya yang tinggi. Pengeringan merupakan metode yang efektif untuk memperpanjang masa simpan wortel, salah satunya dengan menggunakan alat pengering tipe rak (tray dryer). Namun, efisiensi proses pengeringan sangat dipengaruhi oleh keseragaman distribusi suhu dan aliran udara di dalam ruang pengering. Penelitian ini bertujuan untuk mengevaluasi distribusi suhu dan aliran udara pada tray dryer menggunakan pendekatan Computational Fluid Dynamics (CFD) selama proses pengeringan wortel. Simulasi dilakukan pada tiga variasi suhu (50°C, 60°C, dan 70°C) dan dua kecepatan aliran udara (2 m/s dan 3 m/s) dengan bantuan perangkat lunak SolidWorks, ANSYS Fluent, dan Origin. Hasil simulasi menunjukkan bahwa distribusi suhu dan aliran udara tidak merata, terutama pada bagian tengah dan atas alat pengering. Ketidakteraturan ini dapat menyebabkan pengeringan yang tidak seragam dan menurunkan kualitas produk akhir. Validasi dengan data pengukuran menunjukkan bahwa model simulasi memiliki tingkat kesalahan kurang dari 4%, sehingga dapat dianggap cukup akurat untuk digunakan dalam perancangan dan optimasi sistem pengeringan yang lebih efisien.

Abstract

Hand washing is the most important thing because it is simple and most influential in maintaining health caused by infectious diseases. Washing hands should use clean water and be free from germs. Hand washing in public handwashing stations must be carried out carefully because physical contact between users and faucets or soap dispensers can cause disease transmission or epidemics between users. Therefore, ergonomic and semi-automatic handwashing tools are made to reduce physical contact between users and these tools. The existence of the market in everyday life is essential for the community in meeting their daily needs. This activity aims to design, manufacture, and carry out the method of introducing handwashing tools. This service activity took place at the Banda Aia Market, Pasie Nan Tigo Village, Koto Tangah District, Padang City. This market is located in Pasie Nan Tigo (PNT) Village, Koto Tangah District, Padang City, the only market in Pasie Nan Tigo Village. The results obtained from this activity are (1) the Banda Aia market community is greatly helped by this hand washing tool, (2) the market community is more interested in washing their hands because they are not worried about contact with the hand washing place, (3) The public gets information about health care methods during the COVID-19 pandemic through health posters affixed to handwashing tools. From the implementation of this activity, it can be seen that awareness in washing hands after activities in the community is not only influenced by awareness alone, but the right tool to increase awareness becomes a habit.

Abstract

The demand for energy-efficient and sustainable agricultural systems is increasing in response to limited arable land and rising food needs. This study aims to evaluate the performance of a solar power system (PLTS) as an energy source in a Nutrient Film Technique (NFT) hydroponic system, assess the effectiveness of artificial lighting powered by PLTS on the growth of pakcoy (Brassica rapa L.), and analyze the technical and economic aspects of the system. An experimental method was used, involving the design and installation of the PLTS and artificial lighting system, energy performance testing, and observation of plant growth parameters over 27 days. The experiment compared the growth of pakcoy cultivated in an NFT system with artificial lighting against a control group grown conventionally without additional lighting. The results showed that the integration of artificial light powered by PLTS enhanced photosynthetic efficiency, as indicated by increased plant height, number of leaves, and leaf dimensions compared with the control. The system also proved to be energy-efficient, with an average solar panel efficiency of 12.98%, peak input power of 3,030.80 W.m-2, and peak output power of 287 W.m-2. The average solar radiation intensity received was 333.26 W.m-2. Overall, the integration of artificial lighting with a solar power system has significant potential to support the development of sustainable hydroponic agriculture.
