Kajian Landing Station Alat Deteksi Dini Tsunami Berbasis Kabel Serat Optik Bawah Laut di Kabupaten Pasangkayu, Sulawesi Barat

The construction of an underwater fiber-optic cable-based tsunami early detection system is planned to be installed in the Makassar Strait with a landing point in West Sulawesi. Land infrastructure such as a Power House (PH), a communication tower, and a Beach Manhole (BMH) is needed to sustain the system's power in order to survive. Therefore, the aim of this scientific paper is to study several alternative landing station locations in Pasangkayu, West Sulawesi and then determine the priority locations. The methods used to achieve these objectives are field observation methods and secondary data analysis based on parameters of land area conditions, environmental conditions, supporting infrastructure, social conditions and licensing systems, and marine activities. These aspects are then assessed to determine the priority of the selected location. The location selected based on the assessment carried out is ALT-02B. In succession, the three priority locations selected from the order of most priority to least priority are ALT-02B, ALT-02A, and ALT-06. This selected priority location is not necessarily the final choice location to be used in the construction of a tsunami early detection system land infrastructure because in the process there are still things to be considered and aspects that are made the main priority for consideration in making decisions.

Elementos Folkcomunicacionais no Discurso do ex-Presidente Lula: Um Registro Histórico do Brasil Ovacionado nas Páginas de The Economist

O presente estudo visa a discutir um registro histórico do Brasil, com base em um olhar elogioso e mesmo eufórico, a seu respeito no jornal britânico The Economist durante o segundo mandato do ex-Presidente Lula. O veículo é considerado por economistas e especialistas do mercado financeiro de todo o mundo como a bíblia do liberalismo mundial; com essa “marca” The Economist vai do pânico com a iminente vitória do ex-líder sindical em 2002 ao entusiasmo com a postura do ex-Chefe de Estado da maior potência econômica latino-americana em menos de uma década! Este paper, com alicerce teórico envolto pela análise de discurso e por importantes aspectos folkcomunicacionais, faz um retorno a um passado histórico recente, no entanto, extremamente distante da realidade brasileira atual, na qual a crise permeia diversos setores e a linguagem folk, leve, pacífica deu lugar ao discurso do “negacionismo” face a demandas sociais de ordem emergencial, como é o caso da fome, do emprego, da saúde pública. Por fim, o que foi “marolinha” na economia do Governo Lula, se transformando em elogios e exemplo para todo o planeta, parece hoje um longínquo registro histórico. É o referido registro que ora se apresenta, envolvendo o discurso como o eixo central da imagem folk de um ex-presidente brasileiro que trouxe elogios e euforia ao seu país. Brasil; Folkcomunicação; Lula; The Economist. The present study aims to discuss a historical record of Brazil, based on a complimentary and even euphoric look, about it in the British newspaper The Economist during the second term of former President Lula. The vehicle is regarded by economists and financial market experts from around the world as the bible of world liberalism; with this "brand" The Economist goes from panic with the imminent victory of the former union leader in 2002 to enthusiasm for the former Head of State of Latin America's greatest economic power house in less than a decade! This paper, with theoretical foundation surrounded by discourse analysis and important folkcommunicational aspects, makes a return to a recent historical past, however, extremely distant from the current Brazilian reality, in which the crisis permeates various sectors and the folk language, light, peaceful gave way to the discourse of "denialism" in the face of social demands of emergency order, as is the case of hunger , employment, public health. Finally, what was "marolinha" in the economy of the Lula Government, turning into praise and example for the whole planet, today seems a distant historical record. It is the aforementioned record that now presents itself, involving the speech as the central axis of the folk image of a former Brazilian president who brought praise and euphoria to his country. Brazil; Folkcommunication; Lula; The Economist. El presente estudio pretende discutir un registro histórico de Brasil, basado en una mirada complementaria e incluso eufórica, al respecto en el diario británico The Economist durante el segundo mandato del expresidente Lula. El vehículo es considerado por economistas y expertos en mercados financieros de todo el mundo como la biblia del liberalismo mundial; con esta "marca" The Economist pasa del rey del pánico con la inminente victoria del ex líder sindical en 2002 al entusiasmo por la antigua casa de poder económico del ex Jefe de Estado de América Latina en menos de una década. Este trabajo, con fundamento teórico rodeado de análisis del discurso y aspectos folclóricos importantes, hace un retorno a un pasado histórico reciente, sin embargo, extremadamente distante de la realidad brasileña actual, en la que la crisis impregna diversos sectores y el lenguaje popular, ligero, pacífico dio paso al discurso del "negacionismo" frente a las demandas sociales del orden de emergencia, como es el caso del hambre , empleo, salud pública. Finalmente, lo que fue "marolinha" en la economía del Gobierno de Lula, convirtiéndose en elogios y ejemplo para todo el planeta, hoy parece un registro histórico lejano. Es el mencionado registro que ahora se presenta, que involucra el discurso como eje central de la imagen popular de un ex presidente brasileño que trajo elogios y euforia a su país.

INTEGRASI MODUL ENERGI SURYA UNTUK MEMBANTU SISTEM KELISTRIKAN DI PONDOK PESANTREN DARUL BAYAN KECAMATAN JATINANGOR KABUPATEN BANDUNG

Pesantren Darul Bayan di bawah naungan pembinaan Yayasan Darul Bayan Pembangun Peradaban terletak daerah di Desa Cilayung Kecamatan Jatinangor Kabupaten Sumedang Jawa-Barat. Luas tanah yang dimiliki pesantren Darul Bayan sekitar 3000 (tiga ribu) meterpersegi, Di samping kegiatan kepesantrenan, Yayasan Darul Bayan Pembangun Peradaban membuat sekolah non formal (madrasah alquran) yaitu mulai dari tingkat SD sampai SMA, Jumlah santri kurang lebih ada 250 orang putra-putri, dua keluarga yang menetap, dan 20 orang guru. Pemenuhan energi listrik untuk kebutuhan sehari-hari di pesantren ini bersumber dari PLN dengan total daya sebesar 4400 VA. Biaya bulanan untuk penggunaan listrik rata-rata mencapai Rp 1.500.000 (satu setengah juta rupiah) tiap bulan. Biaya sebesar itu tentu sangat memberatkan, sebab tidak semua santri berkecukupan untuk membayar sumbangan pembinaan pendidikan (SPP) sebagai sumber biaya operasional bulanan. Oleh karena itu perlu ada upaya untuk meringankan biaya yang ditanggung pesantren. Masalah lain adalah keandalan listrik atau gangguan terputusnya saluran dan drop tegangan, serta sistem penerangan gerbang depan serta penerangan bilik di pesantren belum memadai. Untuk membantu meringankan biaya bulanan dan meningkatkan keandalan kelistrikan, maka dipasang Pembangkit Lisrik Tenaga Surya (PLTS). Sistem tersebut meliputi panel sel surya (gabungan beberapa modul sel surya), baterai, inverter, monitoring-kontroler, saklar, stop kontak, sensor photocell, dan pelengkap lainnya. Panel sel surya akan mengalirkan energi menuju baterai pada siang hari, pada malam hari lampu dapat dinyalakan secara otomatis maupun manual. Power House atau Pusat Daya PLTS akan dipasang di bangunan utama pondok pesantren, sehingga pemantauan PLTS akan lebih mudah.

Analytical Approach to Sampling Estimation of Underwater Tunnels Using Mechanical Profiling Sonars

Hydroelectric power plants often make use of tunnels to redirect the flow of water to the plant power house. Such tunnels are often flooded and can span considerable distances. Periodical inspections of such tunnels are highly desirable since a tunnel collapse will be catastrophic, disrupting the power plant operation. In many cases, the use of Unmanned Underwater Vehicles (UUVs) equipped with mechanical profiling sonars is a suitable and affordable way to gather data to generate 3D mapping of flooded tunnels. In this paper, we study the resolution of 3D tunnel maps generated by one or more mechanical profiling sonars working in tandem, considering synchronization and occlusion problems. The article derives the analytical equations to estimate the sampling of the underwater tunnels using mechanical profiling sonars (scanning sonars). Experiments in a simulated environment using up to four sensors simultaneously are presented. We also report experimental results obtained by a UUV inside a large power plant tunnel, together with a first map of this environment using a single sonar sensor.
