Sistem blowdown pada PLTU digunakan untuk mengontrol dan membuang kandungan solid dalam sisa air pemanasan. Dampak negatif kenaikan tekanan fluida secara kontinyu adalah terjadinya deformasi pipa blowdown karena tegangan pipa melebihi nilai tegangan yang diijinkan. Artikel ini menyajikan hasil penelitian dalam menganalisis kenaikan tekanan fluida terhadap tegangan dan fleksibilitas pipa blowdown A106 Grade A berdasarkan ASME B31.3 Piping Process. Berdasarkan kriteria critical line, pipa blowdown A106 Grade A yang dikategorikan sebagai kategori B harus dikoreksi dengan metode sederhana. Fluida di dalam pipa blowdown telah mengalami kenaikan tekanan menjadi 322,55 psi dan bersifat turbulen. Berdasarkan ASME B31.3, tegangan dan fleksibilitas pipa blowdown masih di bawahnilai yang diijinkan dan sistem perpipaan dinyatakan aman.

The concept of Industry 4.0 is a combination of new technological developments that aim to facilitate human-computer interaction. Higher Education Institutions are currently not separated from the development of the industrial revolution involvement 4.0. Technology has a tremendous influence in the running of all activities of daily living, not least the performance of management in institutions of Higher Education Institutions. The demand to be able to work more effectively and efficiently in producing a product both in the form of goods and services makes PPNS have to keep up with technological developments. PPNS is expected to produce a product, both goods and services, in accordance with the expectations of the stakeholders (students, society and lecturers-employees). One of the problems that often becomes a problem is the bureaucracy that has a long flow. In this study, problems that occur in the PPNS Student Affairs Sector will be raised, namely regarding the approval of student activity proposals from the Student Association (HIMA) by the PPNS Management in Student Affairs under Deputy Director III. There are several steps that can be assisted in the process by using technology, so as to increase the effectiveness of performance in student affairs. Based on these problems and opportunities, a study is proposed with the title Integrated Validation System (IVS) Development to Optimize Student Service Performance in PPNS. With this system, it is hoped that it will help optimize the performance in the field of student affairs so that it can be more effective and efficient in serving requests for student activities at PPNS

One of many things that could help the company to achieve their goals is a good human resource planning. The right calculation to optimize the manpower needs can make a company be more effective, efficient, and productive in finishing their works. In contrast, to increase productivity, the workload would be increasing too. KM. Asia Putra reparation in PT. Adiluhung Saranasegara Indonesia will be used as the object of this research because the project is considered to experience a long delay. The main purpose of this study is to provide recommendations for recruiting more manpower with a workload approach. The method that chosen is NASA-TLX which is a method that calculate workload subjectively. The result from NASA-TLX method recommends the company to add 35 more manpower to reach the optimal number for ship reparation process. With the recommendation, the schedule of ships reparation that was first planned for 25 days could be reduced 18 days. This study has a limitation in the field of cost that could be used as an object for further research.
