Abstract

X, a public railway transportation company, is experiencing challenges in its procurement process, including frequent delays and failures. To support timely project execution and optimal budget utilization, this study applies the Lean Six Sigma methodology through the DMAIC (Define, Measure, Analyze, Improve, Control) framework to analyze inefficiencies and propose improvements. The Define phase identifies key procurement issues and customer expectations; the Measure phase calculates the current sigma level (3.33) and highlights problem patterns; the Analyze phase explores root causes using fishbone diagrams and 5 Whys; the Improve phase presents 13 actionable recommendations; and the Control phase outlines a plan to sustain improvements. The primary issue identified is a 16.81% procurement failure rate, mainly due to bids exceeding the Owner’s Estimate and the absence of qualified vendors. Cost-benefit analysis confirms the feasibility of improvements, showing a Net Present Value (NPV) of IDR 770,512,859, a Benefit-Cost Ratio (BCR) of 1.557, an Internal Rate of Return (IRR) of 108%, and a Payback Period of 1 year. These findings support the implementation of targeted process enhancements to improve procurement performance at PT. X.

Abstract

This study analyzes the impact of digitalization and human intervention in credit decisions on the risk of late payments in multifinance companies PT. XYZ. The digital transformation in the financial industry has shifted the creditworthiness assessment process from a manual system to a fully automated one. The study used a quantitative method with binary logistic regression analysis on data from 533 credit contracts divided into two periods: January–April 2021 (196 contracts with human intervention) and June–September 2021 (337 contracts without human intervention). The variables analyzed included tenor, digital score, effective interest, monthly income, and credit expert involvement in First Payment Default (FPD). The results showed that digital scores had a significant influence on the probability of FPD, with an odds ratio of 1.852 (p = 0.009), meaning that every increase of one unit in digital score increased the probability of FPD by 85.2%. In contrast, the variables of tenor, interest, income, and credit expert intervention did not show a significant influence on FPD. The Chi-square test confirmed that there was no significant difference in FPD levels between credits with and without human intervention (p = 0.148). The model has a classification accuracy of 96.4%, with an AUC value of 0.738, indicating a fairly good discriminating ability. Strict implementation of Know Your Customer (KYC) plays an important role in risk mitigation. These findings provide managerial implications that the digital underwriting system can be relied upon as the main tool in the credit assessment process, supporting the decision of PT.

Abstract

Penelitian ini menelaah penerapan model pembelajaran outdoor learning yang mengintegrasikan nilai-nilai kearifan lokal di Candi Prambanan sebagai pendekatan inovatif dalam mata pelajaran Pendidikan Pancasila dan Kewarganegaraan (PPKn). Latar belakang penelitian didasari oleh kebutuhan untuk menghadirkan pembelajaran PPKn yang lebih relevan dan aplikatif, sebab metode konvensional yang bersifat teoritis belum sepenuhnya efektif dalam membangun karakter sekaligus budaya kewarganegaraan peserta didik secara menyeluruh. Dengan menggunakan pendekatan kualitatif serta metode studi kasus, data dikumpulkan melalui observasi, wawancara mendalam, dan dokumentasi. Temuan penelitian menunjukkan bahwa pembelajaran PPKn di lingkungan Candi Prambanan dapat meningkatkan rasa kepedulian siswa terhadap pelestarian budaya, memperkuat nilai keberagaman, dan mendorong keterlibatan aktif dalam kegiatan sosial. Pembelajaran di luar ruang kelas ini memberikan pengalaman yang nyata bagi siswa sehingga memudahkan mereka dalam menghayati nilai-nilai kewarganegaraan secara lebih dalam. Model pembelajaran outdoor learning berbasis kearifan lokal tidak hanya memperdalam pemahaman siswa terhadap materi PPKn, tetapi juga secara signifikan mendukung pembentukan budaya kewarganegaraan, yakni sikap dan perilaku warga negara yang aktif, bertanggung jawab, serta memiliki kesadaran akan identitas budaya dan kebangsaan. Model ini layak dikembangkan sebagai alternatif metode pembelajaran PPKn yang sesuai dengan konteks sosial dan budaya setempat.
