This is a preprint journal club review of K-Means Method for Clustering Water Quality Status on The Rivers of Banjarmasin by Tien Zubaidah and Nieke Karnaningroem. The preprint was originally posted on INArxiv on December 21, 2017 (link: https://osf.io/g6wkp/). The article is now in review in the ARPN Journal of Engineering and Applied Sciences (submitted December 20, 2017). Original abstract: The surface river water quality in Banjarmasin city tends to decline constantly as the result of direct and indirect waste disposal from various human activities along the river body. This study aimed to determine the vulnerability points against pollution in the rivers of Banjarmasin using clustering techniques with K-means algorithm. The parameters observed include Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Suspend Solid (TSS) and Dissolved Oxygen (DO). The data were collected at eight water monitoring stations on various rivers in Banjarmasin city. With the K-means method, four water quality status were clustered. The result showed that 6 stations observed during the period April to October 2016 were categorized into the heavy polluted cluster with major pollution point of sources came from the domestic and industrial activities.
The following guidelines and email templates are meant to help you start a PREreview journal club at your institution. The first two email templates are for you to send to your department to invite colleagues to your journal club; the last one is for you to send to the authors to let them know you have reviewed their preprint on PREreview. Please let us know if these materials helped you, or suggest changes by emailing us at email@example.com. Thank you!
REQUEST A LIVE-STREAMED PREreview JOURNAL CLUBAt PREreview, we want to take preprint journal clubs to the next level. Live-streamed PREreview journal clubs (LivePREJCs) are hosted via online community calls, allowing anyone with internet or phone-in capabilities to join the discussion. This format promotes inclusivity by following a structure that provides a means to join the discussion silently in written form and vocally. You can request our help to organize a live-streamed preprint journal club by clicking on the link above and filling the form. Here is a list of current and past LivePREJCs.Live-streamed PREreview journal clubs are:Inclusive: anyone, anywhere in the world with a internet or phone connection can joinInformative: you can learn more about the topic by listening to/reading the comments of other researchers in the field and even the authors themselves (if invited)Efficient: if preprint authors are present, they receive feedback in real time. Also, we restrict the live journal clubs to 1 hour to keep the feedback focused and efficientCollaborative: the format encourages contributions from all participants regardless of input style preference, i.e. both vocal and silent writing (etherpadding)Fun: even though the discussions are kept professional and centered around providing constructive feedback to the preprint authors, they are a fun way to meet other people interested in the field.How to get started:Choose a preprint you wish to discuss at a LivePREJC (find out more about what preprints are and where to find them).Find a few other scientists or researchers, preferably at different career levels and from different institutions, who would like to participate in the LivePREJC. Our team will help you recruit more participants if you cannot find them on your own.Fill out this form to formally request a LivePREJC and our logistic support.If you are not the preprint author(s), you can contact the corresponding author(s) and let them know about the LivePREJC. If you don't feel comfortable doing this, please let us know and we will do it on your behalf. You can also choose not to include the author(s) in the discussion. What to expect during the call:LivePREJCs are usually hosted by one or two members of the PREreview team: we will ensure that the conversation around the preprint runs smoothly and stays on time (1 hour); they will take notes and encourage others to take notes on a collaborative etherpad (see below); importantly, they will set the tone for a productive and respectful conversation according to the PREreview code-of-conduct.Preprint authors interested in having their preprint discussed on a LivePREJC, will have the option to be present (recommended). We advise authors to find 5-10 participants (not all the participants need to be experts in the field). Our team will help coordinate the call and, if the authors request it, help recruit more researchers in the field by advertising the call on social media using the #LivePREJC hashtag and any other hashtag related to the research field of the preprint discussed.Once the preprint authors have identified the participants, we will send out a short email with instructions on how to join the LivePREJC and with a copy of the preprint. Participants will be encouraged to read the preprint before the LivePREJC, to keep the discussion short and focused.Authors will be asked to remain in ‘listening mode’ – except when asked a question by participants - until the last 10 minutes reserved for this discussion. This will encourage participants to express their constructive feedback freely and stimulate a productive discussion.Participants will be given the opportunity to give feedback both vocally (with notes taken by one of the PREreview team) and in written form (via collaborative note-taking on a public etherpad that we will set up for each LivePREJC). Here is an example of an etherpad template that will be used for the LivePREJCs.
What are preprints?Preprints are complete pieces of scientific work that have not yet undergone editorial peer reviewed. Preprints are often the same manuscripts that are submitted to a journal for peer review, but are stored on freely accessible public servers (repositories) such that they become available to the whole web community within 1-2 days from submission. Usually preprints are posted on preprint repositories (see below) either before or at the same time as submission to a journal. Most journals will accept manuscripts that have previously been submitted to a preprint repository. A list of copyright and self-archiving polices can be found on Wikipedia and SHERPA/RoMEO.
Where you can find preprints:There are various preprint repositories (see below) and also website platforms where you can search all/most of the preprint repositories, including Prepubmed, Publons, The Winnower, and Academic Karma (please let us know at firstname.lastname@example.org or leave a comment on this page if we missed any). You can search the Research Preprint Servers List to find a preprint server in your field.Below is a list of the most common preprint repositories that post findings in the biological sciences:AgriXiv: a preprint repository for agriculture and allied sciencesarXiv q-bio: a preprint repository for quantitative biology operated by the Cornell University Library. This repository includes manuscripts in the following categories: Biomolecules, Cell Behavior, Genomics, Molecular Networks, Neurons and Cognition, Subcellular Processes, Populations and Evolution, Tissues and Organs, Quantitative Methods, and Other Quantitative BiologybioRxiv: a preprint repository for the biological sciences operated by Cold Spring Harbor Laboratory. This repository includes manuscripts in the following areas: Animal behavior and Cognition, Biochemistry, Bioengineering, Bioinformatics, Biophysics, Cancer Biology, Cell Biology, Clinical Trials, Developmental Biology.

At the top write: Title of the preprint, authors, date of submission, version number, preprint server, and digital object identifier (DOI)Start a new document and invite to your preprint journal club others who want to collaboratively write the preprint review – they will have to sign up on PREreview to be able to edit. Below are a short list of questions that you can have journal club attendants answer (PREreview short participant worksheet, example here), followed by more detailed guidelines on how to structure a more formal and complete peer review (PREreview peer review, example here). Answering the first set of questions will be faster and still povide useful feedback to the authors. However, if the main purpose of the preprint journal club is to train early-career researchers on how to write a peer review, recommend you write the full review as if you were a reviewer for a journal. You can use the comments from the first one to construct the preprint peer review. After you are done writing your your PREreview, you can click on "Document" (top left), "Publish" so that your preprint review will be public and will be assigned a DOI that you can use to advertise your review on social media, email to the authors, and post on the comment section on the server that hosts the preprint you chose for your JC. Additionally with a DOI, your preprint review will be citable! If you got this far, GREAT JOB! Thank you for supporting open science and helping science move forward faster!
