Jurnal Pengembangan Penyuluhan Pertanian (JP3) publishes scholarly manuscripts addressing agricultural extension, rural development, farmer empowerment, smart farming, agribusiness innovation, and related agricultural development issues. Manuscripts must demonstrate academic relevance, methodological rigor, and a clear contribution to knowledge or practice within the journal's Focus and Scope.

The manuscript categories described below are intended to clarify the types of scholarly contributions considered by the journal. JP3 applies transparent editorial and peer review procedures and handles submissions in accordance with publication ethics principles, including those outlined in the COPE Core Practices, particularly the practices on peer review processes, ethical oversight, data and reproducibility, and journal management.

An Original Research Article presents new empirical findings based on quantitative, qualitative, or mixed-methods research. Relevant topics include agricultural extension methods, extension worker performance, farmer participation, technology adoption, farmer empowerment, rural livelihoods, agricultural innovation, smart farming, and agribusiness development. Manuscripts should clearly state the research objectives, describe the methods and data sources, present the results, discuss their significance in relation to existing literature, and draw conclusions supported by the findings.

Authors must provide an accurate account of the research methods and results, describe relevant limitations, and make supporting data available when appropriate and ethically permissible. These expectations are consistent with the COPE Core Practices on Data and Reproducibility.

A Review Article critically synthesizes existing scholarly literature on a topic relevant to agricultural extension and agricultural development. It should identify major concepts, summarize the state of knowledge, compare findings across studies, discuss methodological or theoretical limitations, and identify research gaps or implications for policy and practice. A review must provide a clear rationale and a sufficiently transparent description of how the literature was identified and selected.

Authors should represent the available evidence fairly, acknowledge relevant limitations, and avoid selectively presenting sources in a manner that misleads readers. Transparency in research reporting and data interpretation is consistent with the principles addressed in the COPE Core Practices on Data and Reproducibility.

A Systematic Literature Review uses a predefined and transparent method to identify, screen, assess, and synthesize relevant studies addressing a focused research question. The manuscript should describe the databases or sources searched, search terms, eligibility criteria, screening procedures, data extraction, appraisal methods where applicable, and synthesis approach. Authors should report the review process accurately and acknowledge potential sources of bias or limitations.

Where applicable, authors should follow recognized reporting standards appropriate to the review design and research discipline. The journal's expectation of transparent reporting and reproducibility is informed by the COPE Core Practices on Data and Reproducibility.

A Case Study provides an in-depth analysis of a specific agricultural extension program, farming community, institution, intervention, or agricultural development initiative. The manuscript should explain why the case is relevant, describe its context and evidence sources, present the analytical approach, and discuss lessons that may be useful to researchers, extension practitioners, policymakers, or agricultural communities. Claims should be supported by appropriate evidence, and the limits of generalizing the findings should be acknowledged.

When a case study involves human participants, identifiable personal information, or sensitive community data, authors must address applicable ethical requirements, informed consent, confidentiality, and the protection of participants. These matters are addressed by the COPE Core Practices on Ethical Oversight.

A Community-Based Agricultural Extension Article reports a structured extension intervention, participatory activity, farmer training program, demonstration plot, technology dissemination initiative, or community empowerment activity. The manuscript should explain the intervention's objectives, target participants, implementation process, evaluation methods, outcomes, and practical lessons. It should distinguish measured outcomes from authors' observations or interpretations and provide sufficient methodological detail for readers to understand the basis of the conclusions.

Authors must describe relevant ethical safeguards for community participation, including consent and confidentiality where applicable, and should report the outcomes accurately. The journal's ethical expectations are informed by the COPE Core Practices on Ethical Oversight and Data and Reproducibility.

A Methodological or Applied Innovation Article describes and evaluates a new or improved method, tool, model, digital application, extension communication approach, or agricultural technology relevant to the journal's scope. The manuscript should explain the innovation, its theoretical or practical basis, the development or evaluation procedure, the evidence supporting its usefulness, and its limitations. Descriptions of potential benefits should be distinguished from benefits demonstrated through systematic evaluation.

Authors should provide a transparent account of the procedures and evidence used to evaluate the innovation and should disclose relevant limitations or competing interests. These expectations are consistent with the transparency principles in the COPE Core Practices on Data and Reproducibility and Conflicts of Interest/Competing Interests.

A Policy and Development Analysis examines policies, institutional arrangements, extension systems, or agricultural development strategies using appropriate theoretical frameworks and documented evidence. The manuscript should identify the policy problem, explain the analytical approach, evaluate relevant evidence, and present conclusions or recommendations that follow logically from the analysis. Purely descriptive opinions without a clear scholarly basis may be considered unsuitable.

Authors should disclose relevant competing interests and represent evidence and limitations fairly. The journal's expectations regarding transparency and competing interests are informed by the COPE Core Practices on Conflicts of Interest/Competing Interests and Data and Reproducibility.

All submissions must fall within the journal's scope, present a clearly defined scholarly contribution, follow the journal's author guidelines, and comply with applicable research and publication ethics requirements. The journal's official website states that submissions must follow the prescribed manuscript format and that submissions not meeting the requirements may be rejected before peer review.

Manuscripts must be original submissions and must not involve duplicate or redundant publication. Authors must accurately identify all contributors, disclose relevant competing interests, and provide appropriate information concerning research ethics, data availability, funding, and permissions where applicable. These requirements are informed by the COPE Core Practices, including those on Authorship and Contributorship, Intellectual Property, Ethical Oversight, Conflicts of Interest/Competing Interests, and Data and Reproducibility.

All manuscripts are subject to editorial screening and the journal's applicable peer review process. Editorial decisions are based on the manuscript's relevance, quality, methodological soundness, ethical compliance, and contribution to the field. The journal should describe and manage its peer review procedures transparently, in line with the COPE resources on peer review and the COPE Core Practices.

The manuscript categories listed on this page are editorial classifications proposed for JP3 and should be adopted only after approval by the journal's editorial team. COPE provides publication ethics principles and practices rather than a universal mandatory list of manuscript types. Authors should consult the current journal guidelines or contact the editorial office if their submission does not clearly fit one of the categories above.
