Abstract: This pre-experimental research was aimed to findout whether or not there was a significanteffect of Jigsaw strategy on the ability of the first year students of SMKN 2 Kepenuhan Rokan Huluin comprehending recount text.This research design used one group pre-test and post-test. The sampleofthis research aretakenby using cluster random samplingtechnique and that falls toTata Busana class as big as25 students. The data were collectedby multiple choice tests.The data analyzed by using SPSS 23.00. The result of the data analysis showed that mean scoreof the pre-test was 59.50 and the mean score of post-test was 74.80. In other words, the mean scoreof the post-test was higher than the pre-test. The result also showed that the value of t-test was higherthan t-table (2.49 > 1.71) at significance level of 5%. It can be concluded that Alternative Hypothesis was accepted. Thus, there was a significant effect of jigsaw strategy on the ability of the first year students of SMKN 2 Kepenuhan Rokan Hulu in comprehending recount text. The implication of the findings was that thestudents shouldstudy in group like Jigsaw andmore focus on the given tasks to increase their vocabulary items.KeyWords: Jigsaw, Reading Comprehension, Recount Text

Abstract

Background: The palm oil sector has long been a major contributor to Indonesia’s economy; however, it continues to face criticism for its environmental impact. The circular economy (CE) offers a transformative approach to shift the sector from a linear system to a regenerative model centered on resource recovery, waste reduction, and value retention. This study aims to systematically map CE opportunities across all phases of the palm oil value chain, including pre-production, cultivation, processing, and consumption, and to develop a conceptual framework that supports Indonesia’s transition to sustainability. Methods: A systematic literature review was conducted using the Scopus and Web of Science databases, following the PRISMA protocol. Publications from 2017 to 2025 were analyzed thematically to identify CE opportunities, key drivers, barriers, and interconnections across the value chain. Findings: CE opportunities were identified in every phase of the palm oil value chain. However, integration across phases remains limited, and coordination among stakeholders and institutions has yet to become systemic or well aligned. Conclusion: A holistic conceptual framework that links CE opportunities across all stages of the value chain is essential to enable a sustainable transition in Indonesia’s palm oil industry. Novelty/Originality of this article: This study presents the first comprehensive and phase-based mapping of CE practices in the palm oil sector and introduces an integrative conceptual framework that consolidates fragmented efforts into a coherent model for Indonesia’s sustainable circular transition.

Abstract

Public-Private Partnership (PPP) schemes are increasingly adopted to address infrastructure financing constraints and to support sustainable development objectives. In PPP infrastructure research, semi-structured interviews are widely used to capture in-depth perspectives from key stakeholders. Despite their extensive application, systematic understanding of how these interviews are designed, implemented, and reported remains limited. This study examines the application of semi-structured interview methods in PPP infrastructure research through a systematic literature review of studies indexed in the Scopus and Web of Science databases. The review evaluates research approaches, interview mediums, data collection and analysis techniques, software utilization, interview duration, participant selection criteria, sampling strategies, data saturation, and practices related to rigor and trustworthiness. The findings indicate that semi-structured interviews are predominantly employed within qualitative research designs and are frequently combined with thematic analysis and qualitative data analysis software. Face-to-face interviews and purposive sampling of experienced PPP stakeholders emerge as the most common practices. However, the review also identifies notable inconsistencies in the definition and reporting of data saturation and qualitative rigor across studies. This study contributes to methodological advancement by providing a structured overview of current practices and highlighting areas where clearer and more consistent reporting is required. The findings offer practical guidance for researchers and practitioners seeking to strengthen methodological rigor and transparency in PPP infrastructure research.
