“…Penentuan korosifitas bahan mempengaruhi pemilihan material reaktor. Material yang cocok digunakan pada reaktor yaitu stainless steel (SA 167 grade 3 type 304) karena umum digunakan untuk industri dengan ketahanan tehadap larutan asam dan basa cukup baik, tahan korosi, ringan, dan ekonomis [13]. Reaktor CSTR pada pabrik DPR berguna untuk proses netralisasi yang bertujuan mengurangi kandungan asam abietik pada gondorukem.…”

Potensi pinus cukup besar dan menguntungkan ditinjau dari populasi hutan pinus di Pulau Jawa yaitu sekitar 876 Ha. Salah satu hasil pengolahan pinus adalah gondorukem yang memiliki karakteristik tidak stabil dan mudah teroksidasi. Disproportionated rosin (DPR) merupakan produk inovasi dari gondorukem yang lebih stabil, tahan panas dan oksidasi serta banyak diaplikasikan sebagai adiktif untuk tinta cetak, cat, ban, dan kertas. Proses pengolahan gondorukem menjadi DPR melalui reaksi netralisasi memerlukan reaktor. Tujuan perancangan alat ini adalah mendesain reaktor pada prarancangan pabrik DPR dari gondorukem grade WG dengan kapasitas 3000 ton/tahun. Hasil perancangan reaktor berupa reaktor dengan tipe continuous stirred tank reactor dilengkapi pengaduk jenis three bladed propeller. Reaktor memiliki ukuran sebesar 444,22 m3 dengan tinggi 14,21 m, dan diameter sebesar 3,35 m. Impeller berukuran 13,11 m dengan diameter sebesar 1 m. Reaktor menggunakan desain tutup atas dan bawah berupa standard dished head dengan material penyusun yaitu stainless steel (SA 167 grade 3 type 304). Kata kunci: disproportionated rosin, gondorukem, reaktor CSTR,

“…Sistem transmisi merupakan penyaluran energi listrik dari pembangkit listrik ke gardu induk. Sistem distribusi merupakan penyaluran energi listrik dari gardu induk ke konsumen [2]. Ketika mengalirkan energi listrik pada sistem transmisi maupun sistem distribusi akan muncul jatuh tegangan di sepanjang saluran yang dilewati.…”

Segoromadu Substation has two busbars, namely busbar A and busbar B. Busbar A which has nominal voltage of 150 kV has reached a voltage value of 129.38 kV or experienced voltage drop of 13.75%. The percentage of this voltage drop exceeds a predetermined standard. Therefore, it is necessary to design a shunt capacitor which is then modeled and simulated. Based on calculation and analysis result, capacity of shunt capacitor that should be installed on Bus A is 50 MVAR. After the shunt capacitor was installed, based on simulation, there was an increase of 4.87 kV so the voltage afterward became 139.67 kV or only experienced a voltage drop of 3.19%. So, by installing a shunt capacitor with capacity of 50 MVAR, it can increase busbar voltage of the substation. The shunt capacitor also increases the value of reactive power and current flowing to the busbar.

“…Some of these national steel industries use ASTM A 572 and ASTM A 36 standards, which have potency and capability to be used as steel structures for nuclear power plant construction type Light Water Reactor (L.W.R.) in Indonesia [1]. National steel industries need to develop product innovation for the size dimension and prescribed specifications, codes, and standards.…”

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.
