Abstract

This study aims to analyze research trends on the circular economy and supply chain sustainability using a bibliometric approach and to develop a conceptual model that can guide the implementation of circular economy practices. Data were obtained from the Scopus database and analyzed to identify publication trends, scientific contributions, and collaborations among researchers. The results show a significant increase in research related to the circular economy since 2020, especially in the manufacturing and technology sectors, with a primary focus on recycling, reuse, and remanufacturing as key elements of supply chain sustainability. The developed conceptual model emphasizes the importance of integrating technologies such as the Internet of Things (IoT), blockchain, and Big Data, alongside  the Triple Bottom Line approach, that includes economic, environmental, and social aspects. Collaboration among stakeholders, governments, and consumers is also identified as an important factor in accelerating the adoption of the circular economy. This study contributes to the development of circular economy implementation strategies across various sectors and highlights future research opportunities, such as circular bioeconomy and green innovation. The proposed model is expected to serve as a guide for companies and policymakers in strengthening supply chain sustainability.

Abstract

Servqual merupakan salah satu metode kualitas yang populer digunakan dalam mengukur kualitas layanan. Namun terdapat Keterbatasan pada metode Servqual, keterbatasan ini dapat dicapai dengan integrasi Servqual dan metode Quality Function Deployment (QFD). Tujuan penelitian ini mengintegrasikan Servqual dan QFD dalam melakukan penilaian kualitas layanan dan kepuasan atas layanan pada department IT (information technology) pada industri garmen di Jawa Timur. Metode Servqual untuk menilai kualitas persepsi dan harapan, sedangkan kualitas desain yang dilakukan melalui teknik QFD. Berdasarkan ServQual, ada kesenjangan antara persepsi dan ekspetasi konsumen yaitu dengan rata-rata persepsi 3.96 dan rata-rara ekspetasi 4.36 nilai Gap rata-rata -0.40, dengan demikian semua atribut pelayanan masih di bawah ekspetasi konsumen. Hal ini menunjukan konsumen tidak puas dengan pelayanan yang ada. Pihak Department IT berusaha untuk memperbaiki pelayanan dengan menentukan prioritas Technical Respond.  Berdasarkan QFD prioritas Technical Respond yaitu: mengadakan pelatihan pelayanan, mengadakan program pelatihan berkala, melakukan pekerjaan dengan sop, pengecekan ulang hasil layanan.

Abstract

Self-Estimated Price (HPS) is an assumed cost for the procurement of goods and services in accordance with predetermined provisions and sourced from accountable data. In the field of procurement PT. PJB UP Paiton Unit 1&2 still has several errors in determining the HPS which can result in a failed auction. This study uses simple statistical techniques and also uses the Statistical Product and Service Solutions (SPSS) application so that the price intervals used are maximum HPS and minimum HPS. The price interval is the lowest and highest price limits used as the basis for determining the price of goods and services. In determining the HPS in the procurement of goods and services PT. PJB UP Paiton, calculates the HPS using an operational budget that uses five data sources in its determination. Data sources used in determining the HPS are market price data, previous contact prices, target price proposal prices and comparative study prices. The results of the HPS calculation for the procurement of 500 work vests, so that a minimum HPS of Rp. 52,250,000 and a maximum HPS of Rp. 56,080,200. In addition, the authors calculated the procurement of panel wall installation services with a size of 2.5 x 10 meters, so that a minimum HPS of Rp. 9,761,345 and a maximum HPS of Rp. 9,996,250.

Abstract

Background: Supplier selection in the perishable agroindustry, such as for mushrooms, is a complex and strategic process. It significantly impacts supply chain performance owing to the perishability and quality sensitivity of the products involved. Traditionally, decision-making methods in this area often lack preliminary validation, resulting in suboptimal supplier choice.Purpose: This study aims to integrate bibliometric analysis and multi-criteria decision-making (MCDM) approaches, particularly the Analytic Hierarchy Process (AHP), to develop a robust data-driven model for supplier selection in the mushroom agroindustry.Design/methodology/approach: A systematic literature review using the PRISMA framework and bibliometric analysis of Scopus-indexed articles identified the most relevant MCDM methods. A case study approach involving expert judgment was used to evaluate mushroom suppliers based on the following five criteria: quality, price, delivery, service, and product suitability.Findings/Result: A bibliometric review confirmed that AHP, TOPSIS, and fuzzy logic are the most frequently applied methods. AHP was selected for its strengths in handling both qualitative and quantitative data and validating decision consistency. The results showed that Supplier A had the highest overall score (0.389), followed by Supplier C (0.345) and Supplier B (0.266), with a consistency ratio (CR) below 0.10, validating the assessments.Conclusion: Integrating bibliometric analysis with MCDM methods offers a more objective and evidence-based approach to supplier selection. The developed model enhances decision accuracy, supports strategic sourcing, and ensures quality and timeliness in highly perishable product supply chains.Originality/value (State of the art): This study pioneers the direct integration of bibliometric insights into an MCDM-based decision-making framework applied in a real-world agroindustry context. The methodology is replicable and adaptable across various industries facing similar supplier evaluation challenges. Keywords: supplier selection, multi-criteria decision making, analytic hierarchy process, bibliometrics

Abstract

Perundungan atau bullying masih menjadi masalah serius di lingkungan sekolah yang berpotensi memberikan dampak negatif terhadap perkembangan fisik, emosional, dan sosial siswa. Kegiatan pengabdian masyarakat ini bertujuan untuk meningkatkan pemahaman siswa SMPN 1 Gending, Kabupaten Probolinggo mengenai bahaya perundungan serta strategi pencegahannya melalui sosialisasi perundungan (anti-bullying). Kegiatan ini dilakukan pada bulan Agustus 2025 dengan peserta siswa kelas VIII sebanyak 197 orang. Metode yang digunakan mencakup ceramah interaktif, diskusi tanya jawab, game edukatif, dan simulasi peran (role play). Hasil kegiatan menunjukkan peningkatan pemahaman siswa terkait definisi, bentuk, dampak, dan strategi penanganan perundungan (anti-bullying). Siswa juga menunjukkan antusiasme tinggi, berpartisipasi aktif dalam diskusi, serta mampu mengidentifikasi sikap yang tepat ketika menghadapi situasi perundungan. Evaluasi dari pihak sekolah dan dosen pendamping menegaskan bahwa program ini efektif dalam menumbuhkan kesadaran siswa untuk menciptakan lingkungan belajar yang aman, ramah anak, dan bebas dari perundungan. Dengan demikian, sosialisasi anti perundungan (anti-bullying) ini memberikan kontribusi nyata dalam membangun budaya saling menghormati di sekolah dan dapat direplikasi secara berkelanjutan dengan melibatkan orang tua maupun komunitas.
