Data Mining dan Big Data Dalam Dunia Industri
Get PDFsalah satu metode klastering yang paling populer dan banyak digunakan dalam analisis data tak berlabel. Metode ini bertujuan untuk membagi sekumpulan data ke dalam sejumlah klaster yang telah ditentukan sebelumnya, berdasarkan kedekatan data terhadap pusat klaster (centroid). Proses K-Means dimulai dengan menentukan jumlah klaster (k), kemudian memilih centroid awal secara acak. Setiap data kemudian diklasifikasikan ke klaster terdekat berdasarkan jarak Euclidean. Selanjutnya, centroid diperbarui berdasarkan rata-rata data dalam masing-masing klaster, dan proses ini diulang hingga pusat klaster tidak lagi berubah secara signifikan. Kelebihan metode ini adalah kesederhanaannya dan efisiensi komputasinya, namun K-Means juga memiliki keterbatasan seperti kepekaan terhadap pemilihan centroid awal dan ketidaksesuaian dalam menangani data non-linier atau berbentuk kompleks. Metode ini banyak diaplikasikan dalam segmentasi pasar, pengenalan pola, analisis citra, dan pengelompokan dokumen

Merit System Inefficacy: Analysis of ASN Vulnerability to Regional Head Authority Post-Elections in Indonesia
Get PDFThis study examines whether the merit system effectively protects State Civil Apparatus (ASN) from authority abuse by regional heads following local elections in Indonesia. Through normative legal research employing conceptual and statutory approaches, the study critically analyzes the implementation gap between merit system regulations and post-election personnel practices. Document analysis of relevant legislation, administrative court decisions, and semi-structured interviews with KASN members and affected civil servants reveal three key findings. First, the institutional design placing regional heads as both political officials and Civil Service Development Officers creates inherent conflicts of interest that systematically undermine merit principles. Second, oversight mechanisms lack enforcement authority, with KASN recommendations frequently ignored without consequences. Third, post-electoral political dynamics drive personnel decisions based primarily on political loyalty rather than competence, manifesting in systematic bureaucratic reshuffles that disrupt institutional continuity. The research concludes that despite comprehensive legal frameworks, Indonesia's merit system fails to protect civil servants from political interference due to weak enforcement mechanisms and conflicting institutional roles. These findings suggest that structural reforms separating political and administrative functions in civil service management and strengthening oversight institutions with meaningful sanctioning powers are essential for establishing a truly merit-based bureaucracy in Indonesia's decentralized governance system

Get PDFThis study aims to analyze the development of integrated service innovation through the myITS Services platform at the Integrated Service Center (ISC) of Institut Teknologi Sepuluh Nopember (ITS) in an effort to enhance the effectiveness and efficiency of public services in the academic environment. Using a qualitative descriptive approach, data were collected through document analysis, interviews, and observations. The findings were systematically analyzed using SWOT, IFAS, and EFAS matrices to map strategic positions and improvement priorities. The results show that the integration of myITS Services, supported by leadership commitment and an innovation-driven organizational culture, has significantly improved service quality and customer satisfaction at ITS. Internal strengths include advanced information technology utilization and strong cross-unit collaboration, while structural weaknesses persist, such as limited human resource capacity and data ownership egocentrism among units. External challenges involve regulatory changes and the need for robust data security management. This study concludes that digital service innovation, when supported by integrated governance and collaborative participation, is both feasible and impactful in the higher education sector. However, the research is limited to a single institution and qualitative scope, suggesting future studies adopt a comparative and quantitative approach to measure efficiency, cost savings, and user satisfaction, as well as explore opportunities for artificial intelligence-based service automation

Get PDFPT. Primayudha Mandirijaya is a manufacturing company operating in the textile sector. Customer satisfaction is the main goal. Therefore, production quality always comes first. However, there are problems in making this happen, namely that there are often defects in spools of 20s polyester, because these defects greatly exceed the production limit set by the company, namely 5% of total production. The aim of this research is to find out directly the problems that occur in the production process, as well as to find out the resolution of problems that occur on winding machines. To make this happen, the Statistical Quality Control (SQC) method is used. To determine the possibility of failure, the Failure Mode and Effect Analysis (FMEA) method is used. SQC is used to control product quality, reduce or prevent product failures, while FMEA is used to identify potential failures in the production process. The results of research using the Statistical Quality Control method, the defect rate of 44.67% in Stitch can be reduced to 43.97% and the defect rate of 36.07% in Swelled Package can be reduced to 29.36%. In the Failure Mode and Effect Analysis method, the factors causing defects are influenced by a lack of attention to components and maintenance on the machine, so the maintenance team is recommended to carry out regular check-ups on the condition of the machine every day. Before repairs were carried out, total defects from January to September reached 68,231.52 or 5.28% of production output. After improvements, the number of defects decreased in October to 6,831.72 or 4.53%. Thus, this research is able to reduce defects in spools of 20s polyester thread by 0.75%

Get PDFThe majority of areas in Indonesia, such as the city of Jayapura, are categorized within zones of moderate to high seismic intensity. On February 9, 2023, a 5.4 magnitude earthquake hit Jayapura, resulting in damage to various structures, including the Cathedral Church. Assessments conducted after the earthquake revealed structural issues, including cracks in walls and significant deflection in the roof truss system. From the structural assessment of the current roof, it was determined that eleven truss elements had failed, and every rafter showed deflection surpassing the permissible limit of L/240. The reinforcement involved steel elements and created a Cremona truss framework with WF 250.125.6.9 and UNP 75.40.5 profiles. Connections were established with chemical anchors and endplates between the steel profiles and 30×50 cm concrete beams, along with welded joints linking the steel elements. Evaluation results indicated that the enhanced structure achieved a secure performance level and complied with applicable, especially SNI 1729:2020 for structural steel design. This situation emphasizes the significance of evaluating buildings after an earthquake and implementing specific reinforcement strategies to regain structural stability and safety.Keywords— steel, performance evaluation, earthquake, reinforcement
