Abstract

Masalah utama yang dihadapi Pemerintah Daerah Provinsi Kepulauan Bangka Belitung saat ini adalah sulitnya mengklasifikasikan data industri rumahan berdasarkan Peraturan Menteri PPPA No 2 Tahun 2016 yaitu pemula, berkembang dan maju. Berdasarkan permasalahan tersebut diusulkan pengembangan algoritma Kmeans yaitu algoritma Dynamic cluster pada K-means dengan tujuan agar dapat menghasilkan klaster yang optimal dalam pengelompokan data industri rumahan dengan membangun aplikasi cerdas berbasis web. Penelitian ini menggunakan metode analisis data mining SEMMA, yang meliputi tahapan-tahapan seperti data sampel, deskripsi data, transformasi data, pemodelan data, dan evaluasi data. 3.466 industri rumah tangga digunakan sebagai sampel data. Kinerja algoritma dievaluasi menggunakan pengukuran validitas klaster Davies Bouldin Index (DBI). Hasil eksperimen menunjukkan bahwa algoritma Dynamic cluster pada K-means memberikan nilai yang optimal pada iterasi ke lima, dengan perolehan sebagai berikut: klaster pemula (C1) diperoleh sebanyak 3214, kemudian klaster berkembang (C2) diperoleh sebanyak 167 dan klaster maju (C3) diperoleh sebanyak 85. Hasil evaluasi validitas klaster menunjukan bahwa algoritma Dynamic cluster pada Kmeans memperoleh nilai DBI lebih kecil dibandingkan dengan algoritma K-means dengan nilai DBI sebesar 0.184. Implementasi algoritma dynamic cluster pada K-means untuk pengelompokan data industri rumahan pada Dinas P3ACSKB di Provinsi Kepulauan Bangka Belitung terbukti menghasilkan kualitas cluster yang lebih optimal.

Abstract

This study addresses the strategic challenges faced by private universities in Indonesia in selecting the most suitable IT project to support digital transformation, comparing a Next-Generation Learning Management System (LMS) and an Integrated University Mobile Super-App. Rather than developing a new method, this study enhances the conventional Analytical Hierarchy Process (AHP) by integrating sensitivity analysis and priority decomposition to improve decision explainability (Explainable MCDM). Expert assessments were collected from five academic stakeholders using pairwise comparisons based on Saaty's scale. Four criteria were assessed: Strategic Alignment, Benefits & Impact, Feasibility & Resources, and Risk Assessment. The results show a narrow preference for the LMS (50.7%) over the Super-App (49.3%), primarily driven by its superiority on the highest-weighted criterion, Strategic Alignment (35.6%), particularly the "Support for Core Educational Goals" sub-criterion. Sensitivity analysis reveals that the ranking would reverse if the Benefits & Impact weight increases from 0.200 to above 0.278. This study provides a transparent, replicable, explainable AHP framework that enables decision-makers to understand not only what is recommended but also why and under what conditions the recommendation changes.

Abstract

CV. YustiKarya as a construction company realizes that the ability to manage project finance is one of the important requirements for smooth project management. CV. YustiKarya often has to manage several projects simultaneously with remote locations. This condition made it difficult for financial staff in the office to manage project financial allocations and also made it difficult for project managers in the field and had to report the status of project expenditures to the office. This difficulty drives CV. YustiKarya is to improve the project's financial management system which originally used a spread sheet to become a web-based information system. Web-based information systems will be developed using object-oriented methods. The object-oriented system development method was chosen because of its modular development capabilities and adapts to system requirements. The information system that is produced is able to create a construction project management system starting from employer entry, contract entry, billing entry, printing proof of receipt, printing proof of expenditure, and generating project income and expenditure reports online. Web-based information systems will automate the financial status of projects whose locations are scattered. This system also makes it easy for directors to be aware of current project developments.
