Abstract

Jumlah cadangan pasir besi sebagian besar tersebar di wilayah pesisir perairan Indonesia,dari pesisir sebelah barat Sumatera, pesisir pantai selatan Jawa juga Bali, pesisir Sulawesi, pesisir Nusa Tenggara Timur (NTT), serta pesisir Papua. Jumlah cadangan keseluruhan untuk bijih sebanyak 173.810.612 ton dan logam sebanyak 25.412.652,62 ton. Tetapi pemanfaatannya belum optimal,karena PT. Krakatau Steel, dan PT. Krakatau Posco baru memproduksi plat baja sebanyak 24.000 sampai dengan 36.000 ton per tahun. Sedangkan kebutuhan plat baja untuk industri perkapalan tiap tahunnya dibutuhkan 900.000 ton per tahun. Dengan kebutuhan bahan baku plat baja berupa besi spons dengan Fe ≥ 60%, PT. Krakatau Steel masih mengimpor dari luar negeri. Buktinya, PT.Krakatau Steel sebelum dan selama tahun 2000-an masih mengimpor Pellet Bijih Besi dari negara Swedia, Chilli, dan Brazil sebesar 3.500.000 ton per tahun. Kondisi ini merupakan penyebab industri baja nasional tidak bisa bersaing dengan industri baja luar negeri, karena bahan baku yang diimpor dikenakan bea masuk. Ini peluang untuk membangun perusahaan bahan baku baja, karena selama ini industri bahan baku baja di Indonesia hanya ada dua perusahaan. Kondisi ini mendorong dilakukannya pembuatan besi spons, dengan proses pembuatan besi spons dengan teknologiyang disesuaikan dengan kapasitas produksi terpasang. Penelitian ini menganalisis pembuatan besi spons dengan menggunakan pasir besi Cipatujah, sebagai bahan baku untuk pembuatan besi spons, dengan hasil yang didapat berupa besi spons dengan kadar tertingginya Fe ≥60,44%. Ini dapatdipakai untuk keperluan bahan baku pembuatan baja PT. Krakatau Steel (PT. KS), karena selama ini PT. KS mengklaim bahwa produk besi spons lokal Fe<60%. Ini dapat mendorong kemandirian bahan baku baja, yang dampak pada kemandirian industri pertahanan.Tetapi pemerintah juga harus melakukan proteksi dan memprioritaskan bahan baku baja produksi nasional untuk produksi baja nasional. Dengan jalan industri baja nasional milik pemerintah membina konsorsium vendor pemasok bahan baku (besi spoin) agar kualitas dan pasokan besi spons berkesinambungan.Kata Kunci: pasir besi, pellet besi, besi spons

Abstract

The maglev system is a technology that uses the repulsive force between magnets to float or levitate an object or vehicle. Maglev trains use electromagnets to counter the gravitational force of an object, so that the object can float in the air. With this technology, the resulting loss between the workpiece and the base can be eliminated. The technology used in this train is Electromagnetic Suspension (EMS). The research began by modeling the maglev system in the form of state space. Furthermore, the stability system model that has been built is analyzed. Finally, it is analyzed how the numerical simulation of an open loop without control is analyzed. The result of this research is that the floating system (maglev) is an unstable system if it is run in an open loop, so the maglev system requires sensors and controls in its operation.

Abstract

Maglev trains are considered for urban transport and intercity transport systems. On low-medium speed Maglev trains, the operating routine is shorter than that of high-speed trains. Therefore, EMS and LIM technologies are preferred from the point of view of construction costs. However, in high-speed operation, EDS and NGO technologies are preferred for handling, and reliability. In addition, as the development of high-temperature superconductors and new types of permanent magnets develop, stronger and more cost-effective magnetic energy will be used for Maglev trains. The authors believe this technology can be utilized not only for railway applications but also aircraft launch systems and spacecraft launch systems. The need for a new and improved transportation system prompted many countries to be interested and seek to develop Maglev railways. However, although Maglev trains have been studied and developed for approximately half a century, few countries have the knowledge and expertise to do so. This review paper attempts to describe the current complete system in detail and summarizes the basic core technologies of Maglev trains from an electrical engineering point of view. The research hopes to be useful for people interested in this to assimilate Maglev train technology including magnetic levitation, propulsion, guidance, and power supply systems.
