RANTAI PASOK INDUSTRI BAJA UNTUK PEMBANGUNAN PLTN DI INDONESIA.Dalam pembangunan Pembangkit Listrik Tenaga Nuklir (PLTN) dibutuhkan material baja untuk pembuatan komponen berat maupun material struktur untuk konstruksi sipilnya. Industri nasional diharapkan mampu memasok komponen baja PLTN khususnya untuk kebutuhan komponen non nuklir. Rantai pasok industri baja sangat diperlukan untuk mengetahui potensi industri baja dari hulu sampai hilir yang diharapkan dapat mendukung pembangunan PLTN tersebut secara berkelanjutan. Jenis baja yang dibutuhkan dalam konstruksi PLTN adalah baja struktur, rebar, pelat baja dan lain-lain. Tujuan penelitian ini adalah mengidentifikasi rantai pasok industri baja dari industri hulu sampai hilir sehingga dapat melihat kemampuan industri nasional dalam memasok kebutuhan baja untuk pembangunan PLTN. Metodologi yang digunakan adalah kajian literatur dan survei industri dengan cara purposive sampling test yakni mengirimkan kuesioner dan melakukan kunjungan teknis ke industri yang dianggap berpotensi memasok komponen baja untuk konstruksi PLTN. Dari hasil analisis terhadap kuesioner dan survei telah diperoleh industri baja Indonesia yang mampu memasok baja untuk bahan konstruksi PLTN non nuklir, yaitu PT. Krakatau Steel, PT. Gunung Steel Group (PT. Gunung Garuda dan PT. Gunung Raja Paksi), PT. Cilegon Fabricators dan PT. Ometraco Arya Samanta. Sedangkan bahan baja untuk komponen utama dengan grade nuklir, seperti bahan baja untuk bejana reaktor dan bejana tekan, industri baja Indonesia belum mampu memasoknya, karena belum memenuhi persyaratan spesifikasi, kode dan standar grade nuklir Oleh karena itu, industri baja Indonesia harus meningkatkan kemampuan, baik dalam pengolahan bahan baku dan kemampuan fabrikasi agar dapat memenuhi persyaratan tersebut. ABSTRACT SUPPLY CHAIN OF STEEL INDUSTRIES FOR THE NUCLEAR POWER PLANT CONSTRUCTION IN INDONESIA.Nuclear Power Plant (NPP) Construction needs steel materials for the manufacturing of heavy components and civil work construction. National industries is expected to supply steel components especially for non nuclear component needs. Supply chain of steel industries is required to know the potency of steel industries from upstream to downstream industries which can support the NPP construction sustainability. The type of steel needed in the NPP construction consist of structure steel, rebar, steel plate, etc. The aim of the study is to identify supply chain of steel industries from upstream industries to downstream industries so that they can supply steel needs in the NPP construction. The methodology used are literature review and industries survey by purposive sampling test which sent questionnaires and carrying out technical visits to the potential industries to supply steel components for NPP construction. From the analysis of the questionnaires and survey, it has been obtained that the Indonesian steel industries capable of supplying steel for construction materials of non-nuclear parts are PT. Krakatau Steel, PT. Gunung Steel Group (PT Gunu...

Changes that occur along with the times have consequences for increasing the need for various resources, especially energy. In Indonesia, various changes that occur will also affect the pattern of energy consumption, both qualitatively and quantitatively. This paper describes various aspects related to change and projects over the next 40 years the pattern and quantitative aspects of energy demand in Indonesia. This study is based on historical data by applying related parameters that influence one another. The methodology used is the application of a modeling system with the software 'Model for Analysis of Energy Demand (MAED)'. The results obtained are a description of Indonesia's energy demand projections until 2060 per sector and the form or type of energy needed. The projection results show that in the next 40 years the total energy demand will increase from 195.0 Mtoe in 2020 to 556.5 Mtoe in 2060. From this amount there is a percentage change in the need for each type of energy between the early years of 2020 to the end of 2060. Motor fuel changed from 28% to 34%, while electricity changed from 24% in 2020 to 28% in 2060. In the demand sector, the share of demand decreased in households from 29% in 2020 to 20% in 2060. While other sectors experienced an increase in share in various values. Transportation rose from 19% to 22%, ACM from 8% to 9%, manufacturing remained 34%, while services rose from 10 to 15%. During study period there two important parameters decrease, those are population growth and energy intensity.

SPESIFIKASI, KODE DAN STANDAR BAJA NASIONAL DAN POTENSINYA UNTUK MENDUKUNG PROGRAM PLTN TIPE LWR DI INDONESIA. Spesifikasi, kode dan standar baja nasional sangat penting diidentifkasi agar dapat dicocokkan atau dibandingkan  dengan spesifikasi, kode dan standar internasional untuk komponen PLTN sehingga industri baja diharapkan dapat berpartisipasi dalam pembangunan Pembangkit Listrik Tenaga Nuklir (PLTN). Spesifikasi kode dan standar  baja mengacu pada ASTM, ASME, AISC dan lain - lain. Tujuan studi ini adalah mengidentifikasi  spesifikasi, kode dan standar baja yang dimiliki industri nasional dan kemudian dicocokkan dengan spesifikasi, kode dan standar baja sesuai standar internasional untuk PLTN. Metodologi penelitian adalah kajian literatur, pengiriman kuesioner, survei dan kunjungan teknis ke industri baja. Disimpulkan bahwa baja struktur pada dasarnya memenuhi persyaratan untuk konstruksi PLTN.Kata kunci: spesifikasi, kode, standar, baja, industriSPECIFICATION, CODE AND STANDARD OF NATIONAL STEEL AND THE POTENCY TO SUPPORT THE NUCLEAR POWER PROGRAMME OF LWR TYPE IN INDONESIA. Specification, codes and standards are important to identify in order to be matched or compared to international specifications, codes and standards for NPP components so that the steel industry is expected to participate in the construction of Nuclear Power Plants (NPPs). The specifications, code and standards of steel refer to ASTM, ASME, AISC and others. The purpose of this study is to identify specifications, codes and steel standards owned by national industries and then compared it to international standards for nuclear power plants. The research methodology is literature review, questionnaire submission, surveys and technical visits to the steel industry. It was concluded that the structural steel basically meets the requirements for NPP construction.Keywords: specification, code, standard, steel, industry

The steel manufacturing industry is an inseparable part of the nuclear power plant construction project. This industry is a business full of dynamics, risks, and challenges. The implementation of risk management becomes an obligation that must be executed in managing this very complex project. In general, risk management in manufacturing includes steps to understand and identify potential problems that may occur, evaluate, monitor, and handle risks. The main risk management objectives are to prevent or minimize adverse effects due to unforeseen events through risk aversion or preparation of contingency plans related to those risks. This paper describes the identification of risk factors and assessments using the Boston Matrix. The results of the analysis show that unrealistic schedules, skill not appropriate, not available equipment, transportation barriers to the workshop, fluctuations in steel material prices, wrong specifications from owner, incorrect interpretation of specifications, misinterpretation of drawings, incorrect volume, material storage, wrong cutting, incorrect installation, and wrong order are factors with moderate and high risk.
