Membangun IPTEK Aeronautics and Astronautics

Flight vehicles are subjected to demanding conditions such as those produced by extreme changes in atmospheric pressure and temperature, with structural loads applied upon vehicle components. 

Consequently, they are usually the products of various technological and engineering disciplines including aerodynamicspropulsionavionicsmaterials sciencestructural analysis and manufacturing

The interaction between these technologies is known as aerospace engineering. Because of the number of disciplines involved, aerospace engineering is carried out by teams of engineers, each having their own specialised area of expertise.

The development and manufacturing of a modern flight vehicle is an extremely complex process and demands careful balance and compromise between abilities, design, available technology and costs. 

Aerospace engineers design, test, and supervise the manufacture of aircraft, spacecraft, and missiles. Aerospace engineers develop new technologies for use in aviation, defense systems, and space.

Hunting the Higgs

By: Prof. David Kaiser, Ph.D. 


CAMBRIDGE – Fifty years ago, particle physicists faced an unexpected challenge. Their best mathematical models could account for some of the natural forces that explain the structure and behavior of matter at a fundamental level, such as electromagnetism and the weak nuclear force responsible for radioactive decay.

But the models worked only if the particles inside of atoms had no mass. How could huge conglomerations of such particles – proteins, people, planets – behave as they do if their constituent parts weighed nothing at all?

Some physicists invented a clever workaround. They suggested that a type of particle exists that had never been detected; it was eventually named in honor of the British physicist Peter Higgs. For a half-century, physicists searched for the elusive “Higgs particle.” Now, following research conducted at CERN, the sprawling particle-physics laboratory near Geneva, the hunt may soon be over.

At first blush, the idea behind the Higgs particle sounds outlandish. Higgs and his colleagues suggested that every elementary particle really ismassless, just as the mathematical models require, and hence all particles would ordinarily zip around at the speed of light. But suppose that everything around us – every single particle in the universe – is immersed in a huge, unseen vat of Higgs particles.

Whenever most kinds of particles move from point A to point B, they continually bump into Higgs particles, slowing their motion. When we observe them, they appear to lumber along like holiday shoppers in a crowded store. From their slow motion, we infer that they have mass.

While a 50-year search for a hypothetical particle reminiscent of a bizarre fairytale might seem quixotic, the Higgs particle stands at the center of the “Standard Model” of particle physics. Every experimental test of the model so far has matched theoretical expectations.

In some striking examples, the agreement between prediction and measurement has stretched out to twelve decimal places, making the Standard Model the most accurate scientific theory in human history. The model successfully accounts for three of the four basic forces of nature; only gravity remains beyond its purview.

Higgs particles might have played an even more substantial role at earlier moments in cosmic history. My own research, along with that of physicists around the world, has focused on what effects Higgs particles might have had just fractions of a second after the big bang – effects that could explain the shape and fate of the universe.

And yet, for all that, we still have no direct evidence that Higgs particles even exist. According to the Standard Model, Higgs particles scatter off each other, so they, too, should have mass. The latest research indicates that Higgs particles (if they exist) should be among the most massive critters of the subatomic realm, more than 120 times as massive as the familiar proton.

To produce such a particle in the laboratory requires revving up protons to nearly the speed of light and smashing them together, which the Large Hadron Collider at CERN accomplishes trillions of times per second. The energetic collisions produce all manner of debris, which physicists carefully track with huge detectors and sift with sophisticated computer algorithms.

Physicists confront two major hurdles in their hunt for the Higgs. First, they must identify patterns in the debris that could have come from the production and rapid decay of a Higgs particle. The sought-after signal is well understood in principle, given what we know about the Standard Model.

So is the background noise from all of the other junk that comes flying out when two protons collide with colossal energy. Physicists searching for a few Higgs-like needles in a mind-bogglingly large haystack must comb their data for anomalies in the debris that cannot be accounted for by known processes.

The second difficulty concerns statistics. The rules of quantum theory, on which the Standard Model is built, are at root probabilistic. There will always be statistical flukes in the data, just as any series of coin tosses can produce an unexpected string of seven heads in a row.

To know with confidence that the coin is ordinary, with no hidden features, one must log a sufficiently large number of coin flips and check whether the data include equal numbers of heads and tails over the long run. After thousands of coin tosses, if the data still show a bias toward heads, one may be justified in thinking that the coin has some unusual properties.

The same holds true for all of the chaff from the protons’ collisions. Before physicists can claim that their anomalies really come from Higgs particles, they must gather enough data to rule out flukes.

At CERN, two independent teams of physicists recently announced that their data were consistent with detection of a Higgs particle, though there remained a 1-in-2,000 chance that the signal came from mundane, non-Higgs processes. So the teams will continue smashing protons together, gathering more data, and sifting for signs of a Higgs.

We might not have the Higgs in hand right now. But the latest news is the strongest indication yet that the 50-year hunt for one of the most fundamental bits of matter might well be coming to a successful conclusion. The next time the CERN teams call a press conference, it could be weighty news indeed.

The Higgs boson particle

The Higgs boson or Higgs particle is an elementary particle initially theorised in 1964, and tentatively confirmed to exist on 14 March 2013.

The discovery has been called "monumental" because it appears to confirm the existence of the Higgs field, which is pivotal to the Standard Model and other theories within particle physics. It would explain why some fundamental particles have mass when the symmetries controlling their interactions should require them to be massless, and—linked to this—why the weak forcehas a much shorter range than the electromagnetic force

The discovery of a Higgs boson should allow physicists to finally validate the last untested area of the Standard Model's approach to fundamental particles and forces, guide other theories and discoveries in particle physics, and potentially lead to developments in "new" physics.

Memahami Energi Terbarukan

Renewable energy replaces conventional fuels in four distinct areas: electricity generationhot water/space heatingmotor fuels, and rural (off-grid) energy services:
  • Power generation. Renewable energy provides 19% of electricity generation worldwide. Renewable power generators are spread across many countries, and wind power alone already provides a significant share of electricity in some areas: for example, 14% in the U.S. state of Iowa, 40% in the northern German state of Schleswig-Holstein, and 49% in Denmark. Some countries get most of their power from renewables, including Iceland (100%), Norway (98%), Brazil (86%), Austria (62%), New Zealand (65%), and Sweden (54%).
  • HeatingSolar hot water makes an important contribution to renewable heat in many countries, most notably in China, which now has 70% of the global total (180 GWth). Most of these systems are installed on multi-family apartment buildings and meet a portion of the hot water needs of an estimated 50–60 million households in China. Worldwide, total installed solar water heating systems meet a portion of the water heating needs of over 70 million households. The use of biomass for heating continues to grow as well. In Sweden, national use of biomass energy has surpassed that of oil. Direct geothermal for heating is also growing rapidly.
  • Transport fuels. Renewable biofuels have contributed to a significant decline in oil consumption in the United States since 2006. The 93 billion liters of biofuels produced worldwide in 2009 displaced the equivalent of an estimated 68 billion liters of gasoline, equal to about 5% of world gasoline production.

Potensi Energi Terbarukan

Renewable energy flows involve natural phenomena such as sunlightwindtidesplant growth, and geothermal heat, as the International Energy Agency explains:
Renewable energy is derived from natural processes that are replenished constantly. In its various forms, it derives directly from the sun, or from heat generated deep within the earth. Included in the definition is electricity and heat generated from solar, wind, ocean, hydropower, biomass, geothermal resources, and biofuels and hydrogen derived from renewable resources.
Wind power is growing at the rate of 30% annually, with a worldwide installed capacity of 282,482 megawatts (MW) at the end of 2012, and is widely used in EuropeAsia, and the United States. At the end of 2012 the photovoltaic (PV) capacity worldwide was 100,000 MW, and PV power stations are popular in Germany and ItalySolar thermal power stations operate in the USA and Spain, and the largest of these is the 354 MW SEGS power plant in the Mojave Desert. The world's largest geothermal power installation is The Geysers in California, with a rated capacity of 750 MW. Brazil has one of the largest renewable energy programs in the world, involving production of ethanol fuel from sugar cane, and ethanol now provides 18% of the country's automotive fuel. Ethanol fuel is also widely available in the USA.

Mengembangkan Energi Terbarukan di Indonesia

Renewable energy is a socially and politically defined category of energy sources. 

Renewable energy is generally defined as energy that comes from resources which are continually replenished on a human timescale such as sunlightwindraintideswaves and geothermal heat.

Indonesia masih tertinggal jauh dalam pemanfaatan energi terbarukan. Jika dibandingkan dengan Jepang dan China, energi terbarukan di Indonesia cenderung mandek. Apa alasannya?

Kendalanya adalah peran swasta yang masih minim. Padahal, peran swasta sangat dibutuhkan kontribusinya dalam mengembangkan energi terbarukan ini.

Mari Kita Kembangkan Energi Terbarukan

About 16% of global final energy consumption comes from renewable resources, with 10%. of all energy from traditional biomass, mainly used for heating, and 3.4% from hydroelectricity

New renewables (small hydro, modern biomass, wind, solar, geothermal, and biofuels) accounted for another 3% and are growing rapidly.
The share of renewables in electricity generation is around 19%, with 16% of electricity coming from hydroelectricity and 3% from new renewables.

While many renewable energy projects are large-scale, renewable technologies are also suited to rural and remote areas, where energy is often crucial in human development.

Renewable energy sources, that derive their energy from the sun, either directly or indirectly, such as Hydro and wind, are expected to be capable of supplying humanity energy for almost another 1 billion years, at which point the predicted increase in heat from the sun is expected to make the surface of the Earth too hot for liquid water to exist.

Energi Terbarukan Untuk Desa

Jika akses ke Teknologi Informasi modern penting bagi pemberdayaan ekonomi, begitu pula akses ke energi, terutama Listrik.

Bagaimana menciptakan energi Listrik dengan harga terjangkau dan dapat diakses oleh semua warga negara?

Menambah sambungan jaringan listrik nasional ke semua desa terpencil di seluruh negeri merupakan kerja besar dan mahal.

Terutama lagi, solusi seperti itu tak ramah lingkungan.

Saat ini bahan bakar fosil sudah menipis dan perubahan iklim karena emisi karbon merupakan ancaman yang makin membahayakan.

Kita ingin menemukan sumber energi yang sesuai dengan kebutuhan ekonomi rakyat tanpa menimbulkan lebih banyak masalah daripada yang dapat diselesaikan.

Sepertinya Tenaga Surya/Matahari, Tenaga Air, Tenaga Angin, Tenaga Gelombang Air laut merupakan alternatif pilihan.

Selanjutnya ialah biogas bentuk energi terbarukan memanfaatkan kotoran Sapi, Unggas, dan limbah lain yang ada di mana-mana.

Tiap desa nantinya mempunyai pusat-pusat produksi energi tersendiri, yang mampu menghasilkan energi bagi warganya sesuai dengan potensi desanya.

Saya sempat berpikir, bagaimana kalau seluruh atap rumah rakyat kita dipasang panel surya?

Mungkin tidak ada cerita lagi mengenai "Aliran" Atau mati listrik.
