Abstract

This research is aimed to investigate the accuracy and cost-effectiveness of numerical simulation method for the study of flow in a waterwheel system by comparing the results to the results of experiment, as well as by comparing the computational load of various solution schemes. The simulation is performed using Ansys Fluent with sliding mesh interface (SMI) method to treat the interface between rotating waterwheel region and static channel region. The governing equations are solved using the SIMPLE and Coupled schemes, and the effects of spatial and temporal resolutions are investigated. In general, the values of torque and power and the flow patterns obtained using numerical simulation are in a good agreement with those obtained using the experiment, which confirms the reliability of the simulation method. Considering the accuracy and computational load, it is recommended to use the Coupled scheme instead of the SIMPLE scheme for numerical simulation using SMI method.

Abstract

This Community Service Activity (PPM) collaborates with the Family Welfare Empowerment (PKK) of Rasau Jaya II Village as a partner. Partners have not used local food, namely sweet corn and sweet potatoes, into fermented beverage products that can increase immunity during the Covid-19 pandemic. It is necessary to increase the mindset of partners in utilizing local food ingredients as strategic potentials in an effort to increase family immunity, science and technology insights, skills and expertise of partners. The purpose of this PPM activity is to increase the insight, understanding, and awareness of partners regarding preventive efforts during the pandemic by increasing immunity through the consumption of local food. In addition, providing science and technology transfer in the form of appropriate technology (TTG) for processing fermented drinks as an effort to increase the added value of local food ingredients through diversification of their processed products. The implementation method in achieving goals and targets is in the form of socializing information on local potential, science and technology, and preventive efforts during the Covid-19 pandemic, transferring science and technology in the form of TTG training in processing fermented drinks, and conducting monitoring and evaluation. The results of the activity are increased insight and understanding of community groups about local food ingredients as a source of fibre, prebiotics, and probiotics; increasing awareness of community groups regarding preventive efforts during the pandemic by increasing immunity through consumption of local food; increased skills of community groups after simple TTG training in fermented beverage processing, and increasing the added value of local food ingredients through diversification of their processed products into fermented drinks.

Abstract

Pada eksperimen untuk mempelajari unjuk kerja turbin air, diperlukan pengukuran beberapa parameter seperti tekanan  dan  debit  air  yang  masuk  ke  turbin  serta kecepatan  putar  dan  gaya  pengereman  turbin.  Untuk mempermudah  eksperimen  tersebut,  dikembangkan sistem  akuisisi  data  otomatis  menggunakan  perangkat keras dan perangkat lunak open source  berbasis Arduino. Pengembangan sistem tersebut dilakukan melalui tahap perancangan,  implementasi  dan  pengujian.  Sistem dirancang  memiliki  pengendali  mikro  yang  membaca sinyal  dari  sensor  tekanan,  debit,  gaya  dan  proximity. Sinyal tersebut diolah dan kemudian ditampilkan ke LCD serta  disimpan ke dalam kartu memori secara berkala. Untuk  mewujudkan  rancangan  tersebut  berbagai perangkat  dirangkai  dengan  papan  pengendali  dan fungsinya diuji dengan memasukkan program tertentu ke pengendali  mikro.  Untuk  perangkat  sensor,  dilakukan kalibrasi  dengan  membandingkan  nilai  pembacaannya dengan  nilai  pembacaan  alat  ukur  komersial.  Hasil pengujian  sistem  keseluruhan  menunjukkan  bahwa sistem  telah  berfungsi  dengan  baik.  Pengendali  mikro telah dapat membaca dan mengolah sinyal dari berbagai sensor, menampilkan  data  ke  LCD,  serta  menyimpan data  ke  kartu  memori.  Dengan  demikian,  pengukuran dan  pencatatan  berbagai  parameter  eksperiman  dapat dilakukan  secara  otomatis,  sehingga  pengujian  unjuk kerja  turbin  dapat  dilakukan  secara  sistematis  dan komprehensif.
