Pengendalian Kerusakan Lingkungan Atas Perizinan Migas Di Kabupaten Banggai Berdasarkan Undang-undang Nomor 32 Tahun 2009 Tentang Perlindungan Dan Pengelolaan Lingkungan Hidup

Masuknya kegiatan USAha Perusahaan PT. DS-LNG (Donggi-Senoro Liquid Natural Gas) di Kecamatan Batui kabupaten Banggai Provinsi Sulawesi Tengah diharapkan dapat mampu mendorong peningkatan pendapatan regional maupun nasional. Pembangunan proyek pengembangan Gas itu dibagi dengan dua konsep yaitu sektor hulu dan sektor hilir. Adapun dalam penulisan ini, penulis mengangkat judul “Pengendalian Kerusakan Lingkungan Atas Perizinan Migas Di Kabupaten Banggai Berdasarkan Undang-Undang Nomor 32 Tahun 2009 Tentang Perlindungan Dan Pengelolaan Lingkungan Hidup.TerkaitUndang-Undang Nomor 32 Tahun 2009 tentang perlindungan dan pengendalian lingkungan hidup di mana UU tersebut berfungsi sebagai instrumen hukum, khususnya kegiatan USAha yang dilakukan oleh DS-LNG yang akan menimbulkan risiko positif ataupun negatif.Dari uraian di atas, penulis mencoba mangangkat masalah: (1) Apakah kegiatan pengolahan proyek pengembangan Gas DS-LNG berisiko menimbulkan dampak bagi lingkungan dan masyarakat; (2) Bagaimana pengendalian dan pencegahan kerusakan lingkungan atas pengolahan Gas oleh DS-LNG menurut Undang-Undang Nomor 32 Tahun 2009 tentang perlindungan dan pengendalian lingkungan hidup. Dalam penelitian ini, penulis menggunakan metode penelitian yuridis normatif. Dimana metode penelitian ini mengkaji asas-asas hukum dan sistematika hukum. Tehnik pengumpulan data dilakukan melalui studi kepustakaan berupa bahan hukum primer, sekunder, maupun tersier. Semua data kepustakaan dikumpulkan, kemudian dianalisis dan hasilnya dituangkan dalam bentuk deskriptif.Jadi berdasarkan hasil analisis penulis, maka dapat ditarik satu benang merah bahwa proyek pengembangan Gas DS-LNG dapat menimbulkan risiko negatif maupun positif

High-Ampacity Power Cables of Tightly-Packed and Aligned Carbon Nanotubes

We characterize the current-carrying capacity (CCC), or ampacity, of highly-conductive, light, and strong carbon nanotube (CNT) fibers by measuring their failure current density (FCD) and continuous current rating (CCR) values. We show, both experimentally and theoretically, that the CCC of these fibers is determined by the balance between current-induced Joule heating and heat exchange with the surroundings. The measured FCD values of the fibers range from 10$^7$ to 10$^9$ A/m$^2$ and are generally higher than the previously reported values for aligned buckypapers, carbon fibers, and CNT fibers. To our knowledge, this is the first time the CCR for a CNT fiber has been reported. We demonstrate that the specific CCC (i.e., normalized by the linear mass density) of our CNT fibers are higher than those of copper.Comment: 14 pages, 8 figure

The dissipative effect of thermal radiation loss in high-temperature dense plasmas

A dynamical model based on the two-fluid dynamical equations with energy generation and loss is obtained and used to investigate the self-generated magnetic fields in high-temperature dense plasmas such as the solar core. The self-generation of magnetic fields might be looked at as a self-organization-type behavior of stochastic thermal radiation fields, as expected for an open dissipative system according to Prigogine's theory of dissipative structures.Comment: 4 pages, 1 postscript figure included; RevTeX3.0, epsf.tex neede

Chirality-Selective Excitation of Coherent Phonons in Carbon Nanotubes

Using pre-designed trains of femtosecond optical pulses, we have selectively excited coherent phonons of the radial breathing mode of specific-chirality single-walled carbon nanotubes within an ensemble sample. By analyzing the initial phase of the phonon oscillations, we prove that the tube diameter initially increases in response to ultrafast photoexcitation. Furthermore, from excitation profiles, we demonstrate that an excitonic absorption peak of carbon nanotubes periodically oscillates as a function of time when the tube diameter undergoes radial breathing mode oscillations.Comment: 4 pages, 4 figure
