Decision Analysis for Selecting Steam Boiler Units in the Detergent Manufacturing Industry Using the Delphi, DEMATEL, and ANP Methods (Case Study: PT. XYZ)
Get PDFBoilers are vital components in the manufacturing industry because they give the heat energy required for industrial processes. The main boiler unit at PT. XYZ has been in use for over 42 years and is exhibiting decreased efficiency as well as increased safety risks. To address these issues, the company plans to upgrade the existing system with a new boiler with a larger capacity. The selection of boiler units has traditionally been guided solely by the lowest price, without consideration for energy efficiency, safety, environmental concerns, or technological needs all of which can significantly increase operating costs and production interruption risks. This study uses a Multi Criteria Decision Making (MCDM) approach to develop an objective and data driven decision making framework using the Delphi technique, Decision Making Trial and Evaluation Laboratory (DEMATEL), and the Analytic Network Process (ANP). The most significant sub criteria in boiler selection are Boiler Efficiency at 100% Load Specific Energy, which has a weight of 11,83%, followed by Initial Investment Cost (10,84%) and Boiler Safety Control System (10, 13%). The Yuanda Boiler was given the greatest priority weight of 0,349374 among the four evaluated options and is therefore recommended as the best choice, followed by the Miura Boiler (0,319063), the Erensen Boiler (0,196042), and the Omnical Boiler (0,13552). The model established in this work offers a clear and comprehensive decisionmaking framework that can help management choose the best boiler investment that is both energy efficient and sustainable

Analisis Postur Tubuh Pekerja Saat Menggunakan Kursi dan Komputer Dengan Metode Rapid Office Strain Assessment (ROSA) di Unit Demin Plant PT. XYZ
No full textThis study aims to analyze the working posture of operators using chairs and computers in the demineralization unit (demin plant) at PT. XYZ by applying the Rapid Office Strain Assessment (ROSA) method. Prolonged computer use with non-ergonomic postures can cause musculoskeletal disorders. The research method used direct observation of two operators with Nordic Body Map (NBM) questionnaires for initial complaint identification, followed by ROSA analysis. The results show that two operators scored 8 on the ROSA scale, which falls into the very high-risk category. This score indicates that the working posture is not ergonomically appropriate and has the potential to cause musculoskeletal disorders. Contributing factors include improper sitting posture not meeting ergonomic standards, absence of adjustable armrests, monitor position too low with viewing angles of 4.38° and 9.43°, monitor viewing distance of 40-45 cm (less than the 50-70 cm standard), and work equipment that does not fully support optimal comfort. Improvement recommendations include using ergonomic chairs with adjustable features, height-adjustable monitor stands, ergonomic workstations, and providing mousepads and portable keyboards. This study contributes to the application of office ergonomics to prevent musculoskeletal disorders in oil and gas industry workers

Get PDFPT XYZ is a company engaged in providing internet services and telecommunication networks. In managing its network services and infrastructure, PT XYZ operates an Integrated Operation Center that monitors all production tools continuously on a 24/7 basis. As part of its development, PT XYZ is leveraging Artificial Intelligence (AI) to accelerate business processes and to ensure more efficient information management. To achieve these goals, effective governance of data and information management is essential. This study uses COBIT 2019, a proven and widely recognized governance framework, to identify and analyze the necessary governance requirements at PT XYZ. COBIT 2019 includes a capability level assessment mechanism based on the Capability Maturity Model Integration (CMMI), which enables the evaluation of existing management practices. Using the design factors method, seven objectives from COBIT 2019 were selected such as EDM03 (Ensured Risk Optimization), APO12 (Managed Risk), APO13 (Managed Security), BAI10 (Managed Configuration), DSS04 (Managed Continuity), DSS05 (Managed Security Services), and MEA03 (Managed Compliance with External Requirements). The results of this study include improvement steps and governance recommendations for each selected objective to reach the target state expected by stakeholders. The current assessment shows that all selected objectives are at capability level 2 (Managed), while the desired target is level 5 (Optimizing). Therefore, improvement measures based on the proposed recommendations and best practices are required. In line with COBIT 2019 framework recommendations, in order to successfully implement AI within existing business processes, PT XYZ must prioritize risk management, data and IT infrastructure security, as well as compliance with rules/regulations, so that the AI adoption is aligned with the plan, safe, effective, and efficien
Development of a Web-Based Application to Analyze the Comments of the Genshin Impact Virtual Community Official
Get PDFOnline games are now evolving into interactive social spaces that give rise to dynamic virtual communities. One of the communities that is quite well-known in Indonesia is Genshin Impact Indonesia Official, which is often the talk of the town on social media. The problem in this study focuses on how the involvement of players in the community has both positive and negative impacts. The purpose of this research is to analyze the comments of community members to recognize the forms of expression and categories of impacts caused. The research data was collected from 100 random comments on the Genshin Impact Player Restlessness Facebook group during the period of July 8–12, 2025. The method used is Directed Content Analysis (DCA) with the classification framework of Belfiore and Bennett, which includes 12 categories of cultural participation impacts. In addition, the analysis is carried out based on the classification of sentiment (positive, negative, neutral). The findings of this study show that most of the comments are positive, especially in the aspects of Personal Well-being, Appreciation of Game Design, and Personal Development. While negative comments are generally related to the issue of Social Stratification and the pressures due to game mechanics. In addition, the research also resulted in a web-based application for the automation of data classification and visualization, which has been proven to facilitate the analysis process
Studi Eksperimental Transmisi Cahaya Pada Bahan Armatur Lampu: Kertas, Kain, dan Akrilik
Get PDFKap lampu (armatur) memainkan peran penting dalam mendistribusikan, menyaring, dan menyebarkan cahaya pada pencahayaan buatan. Karakteristik transmisi cahaya sangat dipengaruhi oleh sifat material seperti transparansi, homogenitas permukaan, dan ketebalan. Penelitian ini mengkaji performa tiga bahan umum—kertas, kain, dan akrilik—untuk memberikan dasar ilmiah dalam pemilihan material yang tepat berdasarkan fungsi dan estetika. Penelitian ini bertujuan untuk menganalisis dan membandingkan karakteristik transmisi serta penyebaran cahaya dari tiga material kap lampu, yaitu kertas Concorde 80 gsm, kain belacu 150 gsm, dan akrilik putih 2 mm, melalui pengukuran objektif dan observasi subjektif. Metode eksperimen kuantitatif digunakan dalam ruang terkontrol. Pengukuran objektif intensitas cahaya (dalam lux) dilakukan dengan lux meter pada jarak 50 cm dan 100 cm dari sumber cahaya LED 5W. Observasi subjektif terhadap kualitas penyebaran cahaya dilakukan oleh tiga responden. Hasil menunjukkan akrilik memiliki intensitas cahaya tertinggi (56,3 lux pada 50 cm; 40,3 lux pada 100 cm) dan penyebaran paling merata. Kain belacu menempati posisi menengah (35,9 lux; 20,6 lux), sementara kertas Concorde memiliki performa terendah (30,1 lux; 17,3 lux) dengan penyebaran terbatas. Temuan ini merekomendasikan akrilik untuk aplikasi pencahayaan fungsional yang membutuhkan transmisi tinggi, kain untuk pencahayaan atmosferik, dan kertas untuk elemen dekoratif. Penelitian ini memberikan panduan berbasis data untuk seleksi material dalam desain pencahayaan interior
