The drying process was a method of evaporating moisture from the material to extend its shelf life. One of the drying methods used was Tray Dryer machine. Tray Dryer machine was needed to do research in Laboratory to know optimal temperature, energy capacity, humidity which needed in drying process till the material was dry and cooked properly. During the drying process, data on changes in materials weight relative to air flow temperature and time was needed to determine the reduce water content in real time. So, this Tray Dryer needed to be equipped with an electronics substrate weight meter. The substrate weight measurement process used three load cell sensors with the capacity of 5 kg to measure changes in substrate weight relative to time and airflow temperature. The Tray Dryer was equipped with the data acquisition capabilities required for the real time monitoring process of the substrate weight condition regarding temperature, air flow, and time parameters. As a result, the substrate weight measurement system on the Tray Dryer had a weight reading accuracy of ±0.45%. The dynamic changes in the weight of materials dried using Tray Dryer decreased by 29% with temperature of 80 C and airflow speed of 2 m/s for 75 minutes. The changes in the weight of this material could also be monitored in graphical form using LabVIEW and stored on Ms. Excel.

Our ethic statements are based on COPE’s Best Practice Guidelines for Journal Editors.
Publication decisions
The editor is responsible for deciding which of the articles submitted to the journal should be published.
The editor may be guided by the policies of the journal's editorial board and constrained by such legal requirements as shall then be in force regarding libel, copyright infringement and plagiarism. The editor may confer with other editors or reviewers in making this decision.
Fair play
An editor at any time evaluate manuscripts for their intellectual content without regard to race, gender, sexual orientation, religious belief, ethnic origin, citizenship, or political philosophy of the authors.
Confidentiality
The editor and any editorial staff must not disclose any information about a submitted manuscript to anyone other than the corresponding author, reviewers, potential reviewers, other editorial advisers, and the publisher, as appropriate.
Disclosure and conflicts of interest
Unpublished materials disclosed in a submitted manuscript must not be used in an editor's own research without the express written consent of the author.
Duties of Reviewers
Contribution to Editorial Decisions
Peer review assists the editor in making editorial decisions and through the editorial communications with the author may also assist the author in improving the paper.
Promptness
Any selected referee who feels unqualified to review the research reported in a manuscript or knows that its prompt review will be impossible should notify the editor and excuse himself from the review process.
Confidentiality
Any manuscripts received for review must be treated as confidential documents. They must not be shown to or discussed with others except as authorized by the editor.
Standards of Objectivity
Reviews should be conducted objectively. Personal criticism of the author is inappropriate. Referees should express their views clearly with supporting arguments.
Acknowledgement of Sources
Reviewers should identify relevant published work that has not been cited by the authors. Any statement that an observation, derivation, or argument had been previously reported should be accompanied by the relevant citation. A reviewer should also call to the editor's attention any substantial similarity or overlap between the manuscript under consideration and any other published paper of which they have personal knowledge.
