Building Human and Sustainability environments

Recently, was booming a YouTube video with the title SEXY KILLER and I’m sure that almost all of you have been seeing it. The video duration more than an hour, but it worth because of the quality of those film documentary very epic and maticulous.

So many perspectives on how to represent the main-value that will deliver, but I just want to argue my insights into that video. Everyone needs the energy to live our life and of course, the video showing us about how human are utterely dependent on electricity. How to esteblish and create electricity is to build a power plant. Coal ( main discussion in the video) is the cheapest alternative that we can get through it. The natural resources that well-provide by universe that consist if 2 types they are renewable resource and un-renewable reaources. Coal was un-renewable resources so that means that someday the source of energy if we just depend on it, soon as possible well be depleted. The coal will be out of stock. Besides the enviromental issues that causing by coal, social issues also complicated. The lump of coal get from mining possessed that caused so many problems of civilization. We know that there are governance that has invoked the regulation how to operad coal mining. The process to rearrange those regulation need time to observation- testing-examination until announced, and of course, that regulation never intend to make no one feel damnify.

Cahaya Tauhid#1

A lonely drive went to home this evening, I was heard a 92.30 Mhz frequency Radio ( I forgot the name),

He was Aa' Gym shared about How Prophet Muhaammad SAW keeps his words. He never speak something that unnecessary, so he merely to say something. But, in case when He said something, those sentences shoud be going into thousand miles away pinetrating our soul. So deep and meaningful. His word it was like a root that absorbed nutrient from soil that make the tree fertil. But everyone know that root was underground.

That was figure of our Prophet Muhammad SAW, he provide our tauhid its like a root. Its underground but can make a very tough tree and beautiful flower

-n--

Everyone will pass one of above I thought

“Perhaps the saddest thing, Is that one moment, you’re in love, or you’re best friends, or you’re in a committed relationship, And the next; you’re just a nuisance, you’re blocked without any good explanation, you’re just another stranger. Or worse yet, you’re forgotten completely.”

— Excerpt from a Book I’ll Never Write, Perhaps the Saddest Thing

Subhanallah , so many sight-of-landscape to seeking every positive side of life (hikmah)

Menjadi Pembelajaran Berharga

Jika kamu pernah ditinggalkan, atau dikecewakan, atau tentang apapun yang membuat hubunganmu dengan seseorang menjadi tidak begitu semenyenangkan dahulu. Entah tentang pertamanan atau kisah cinta. Kemudian kamu melihatnya hari ini, orang itu tumbuh bahagia dan sukses bahkan mungkin kamu merasa dia segala lebih darimu. Lebih bahagia, lebih sukses, segala kelebihan yang membuatmu mungkin sedikit iri.

Maka, berbahagialah.

Sebab barangkali memang harus demikian ceritanya. Dan kamu adalah seseorang yang menjadi jalan baginya untuk mendapatkan apa yang dia dapatkan saat ini. Dan kamu adalah seseorang yang menjadi perantara pembelajaran-pembelajaran berharga yang berhasil dia ambil dalam hidupnya.

Meski, mungkin itu harus membuat hubunganmu dengannya menjadi tidak menyenangkan. Tapi bukan di situlah titik fokusnya. Melainkan tentang bagaimana setiap orang sebenarnya menjadi perantara orang lain dalam meniti takdirnya, memperoleh pemahaman dan pembelajaran hidupnya.

Seperti setiap hari kita bertemu dengan banyak orang, dari mulai pedagang di pasar, tukang parkir, supir bus, dan orang-orang yang tidak kita duga silih berganti. Barangkali, dari pertemuan tak terduga itulah pembelajaran hidup disematkan, juga takdir kita kemudian bekerja, dan bisa jadi berubah.

Jika kamu kemudian mengeluh dan bertanya-tanya mengapa dia bisa menjadi lebih dari kamu. Pertanyaan itu justru lebih layak ditanyakan ke dirimu sendiri, apakah kamu sudah berhasil mengambil pembelajaran dari kejadian yang menimpamu dan orang tersebut?

Jika dia berhasil, mengapa kamu belum juga menemukan pembelajaran itu?

No matter how hurt you are, you will always find comfort with Allah.

[SERI AYAT 198 AL-MAIDAH]

Dahulu, saya pernah dengar dari teman saya bahwa "Orang yang paling cerdas adalah orang yang paling takut akan kematian", saya masih menerka-nerka bagaimana makna sebenarnya dari kalimat tersebut.

Tahun berganti tahun, tak terasa waktu berjalan begitu cepatnya tetapi banyak perubahan karenanya, dari waktu ini saya belajar banyak hal, termasuk kalimat yang satu ini.

Kesimpulan saya adalah orang cerdas diberi karunia oleh Allah SWT untuk memahami alam, memaknai setiap kejadian sebagai hikmah dan anugrah

Orang cerdas diberi karunia oleh Allah untuk berfikir jangka panjang, menyadari bahwa kehidupan tak cukup sampai di dunia saja. Ada kehidupan kekal di akhirat nanti. Orang cerdas menyadari bahwa kesempatan didunia ini digunakan untuk mencari ilmu sebagai bekal, mencari surganya Allah SWT.

Orang cerdas tahu antara sebab dan akibat atas segala perbuatannya serta tutur katanya, bahwa segala sesuatu yang diperbuat dan diperoleh didunia ini akan dihisab dan dimintai pertanggung jawabannya oleh Allah SWT di akhirat kelak.

Orang cerdas memiliki iman di dada, meyakini bahwa firman-firman Allah SWT dalam Al-Quran dan Al- Hadist adalah cahaya dan pedoman kehidupan ketika di dunia.

Orang cerdas menyadari bahwa dunia ini sungguh fana, mereka tidak akan terperdaya oleh gemerlap dunia dan seiisinya ini.

Orang cerdas mengetahui betul bahwa buah dari segara kesabaran didunia ini adalah surga, seperi dalam surat Al-Maidah: 198

"Namun orang-orang yang bertakwa kepasa Tuhan mereka, mereka akan mendapatkan surga-surga yang sungainya mengalir dibawahnya, mereka kekal didalamnya sebagai karunia dari Allah SWT. Dan apa yang ada di sisi Allah lebih baik bagi orang-orang yang berbakti"

Alhamdullilah,

Masih belajar ilmu ikhlas, semoga kita semua termasuk golongan orang-orang yang cerdas.

Jogja masih berhati nyaman kok

Jogja (sejenak) Berhenti Nyaman

Apakah karena manusianya yang tanpa henti menebar polusi atau karena alam semesta yang sedang berkonspirasi mengerjai manusia di jogja sehingga Jogja sedang panas-panasnya. Panas dalam artian sebenarnya, teman. Siang di Jogja sekarang ini menyuguhkan hawa yang akan mengeringkanmu dan terik yang siap menyengatmu.

Yang sering kami rasakan adalah ketika pergi mencari tempat makan siang. Bagi kami mahasiswa bermotor yang kepanasan ketika siang dan basah ketika hujan, melewati teriknya siang menjadi sebuah perjalanan (menantang) memenuhi nafsu perut. Udara dan angin tidak lagi menyejukkan. Aspal panas dan asap kendaraan menambah nelangsa. Lampu merah seakan timer mikrowave, seakan memasakmu selama 60 detik. Taukah apa yang kami cari ketika sampai di tempat makan? Es Teh, oasis gelasan. 

Masih belum bisa membayangkan betapa panasnya jogja di siang hari saat ini? Mari ke Jogja. Jogja akan menyambutmu dengan ketidaknyamanannya. Mungkin Jogja lagi sebal dengan kita yang lalai merawatnya. Tapi ingat, jogja (hanya sejenak) berhenti nyaman.

Spatial References System

I believe that all of you ever looked, glanced, or found a Map, it’s could be widget Map in your smartphone, In the office wall, in the classroom, In the reading corner in the center of the city, Map showing the direction and place information. Nowadays we do not need to worry of getting lost in the new place because the dynamic map on your smartphone always leads you into the right direction, just need to type the destination and with GPS signal the map will give you the best direction, effective distance and also give you the estimated time arriving.

So, have you ever asked how to build or create a map? How it’s could find an efficient direction? How it could show the right position with incredible accuracy? The answer is, it has a Spatial Reference System. When we were in elementary school, our teacher teaches us about Latitude and longitude imaginary line. In order to explain about Spatial References System, that would help a lot. The most simplification to explain above that, humankind who lives in the tropical area w= that have round 0 – 10-degree coordinate have a different condition with an area that in 23..5 – 60 degree coordinate in latitude line.

Spatial References System or also known as Coordinate References System (CRS) commonly used in the geodetic subject to give position projection.  CRS consist of local, regular, and global-based coordinate system that has been defined by Open Geospatial Consortium  (OGC that lately knows as Open GIS Consortium) a nonprofit research organization worldwide. They have committed to interoperate location and develop geospatial technology.

Furthermore, if we want to build a map, we need the SRID integer to define map projection using EPSG Geodetic Parameters Dataset. For example, In Indonesia, we use EPSG 4326 which mean we used spatial references WGS 84 for global spatial references. So, what is EPSG? EPSG acronym from European Petroleum Survey Group. EPSG has a spatial code defined by the International Association of Oil and Gas Producers. The IOP’s EPSG Geodetic Parameter Dataset is a collection of definitions of coordinate reference systems and coordinate transformations, which may be global, regional, national or local in application.

Back then in CRS, coordinate system compound from one coordinate system and one datum. A coordinate system is a set of mathematical rules for specifying how coordinates are to be assigned to points, such as affine, cylindrical, Cartesian, ellipsoidal, linear, polar, spherical, vertical, etc. A datum is a set of parameters that define the position of the origin, the scale, and the orientation of a coordinate system. The main subtypes of coordinate reference system are: geodetic, vertical, engineering, and image; additional subtypes are: derived, projected, and compound.

Here the example of coordinate system worldwide

-          Universal Transverse Mercator coordinate system

-          British national grid reference system

-          Hellenic Geodetic Reference System 1987

-          Irish grid reference system

-          Irish Transverse Mercator

-          Israeli Transverse Mercator

-          Israeli Cassini Soldner

-          Jordan Transverse Mercator

-          Lambert conformal conic projection

-          International mapcode system

-          Military Grid Reference System

-          United States National Grid

So, All an overview of spatial Coordinate System and the next chapter, I will discuss Coordinate Transformation System.

The Art of Structure Engineering: Thomas Telford Bridges

The structure engineering was so powerful, they construct and design everything with efficient cost and elegance appearance. The combination of art and engineer or we can also be called it a combination of civil engineering and architecture engineer.

Chiefly, This section I want to discuss Great Britain and study the works

of Thomas Telford, and also two other men named Stephenson and Burnell.

I'm going to begin each section by defining some section goals and in this section,

the goals are to show how the definition and ideals of structural art began,

and as I mentioned, they began in Great Britain, Thomas Telford and also contrast the early of the iron bridge.

Come up with 3 collaboration in 3 aspects to analyses and give critique both the technical

and aesthetic aspects of the bridge design, These are efficient, elegance, and also the economy. The relation between 3 aspects shown by the picture below.

So with these changes, from the scientific point of view, we have a new material that is born

of the Industrial Revolution-iron. This revolution. From a social point of view, we have a new opportunity, industrialization. And from the symbolic point of view, we have a new vision, a new form for structures that we define as structural art. Before we going into so far, we should be understanding several keys to helping us understand,

 Ambiguous Form: Unclear how the forces are being carried

Cable : Structural element to resist tension only

Cantilever : a protruding rigid structural element, such as a beam or girder, anchored only at one end

Compression: application of inward forces to different points

Density : Mass per unit volume

Span : longest unsupported length

Spandrel: The planar like structure that connects the arch to the deck

Suspenders: vertical members suspending the deck, or carrying the loads to the main cable

Tension : Describes the pulling force exerted by each end of a road, truss member, or similar three dimensional object

 The raised of Iron-bridge, started by the regulation in the UK, One is we have Queen Elizabeth who outlaws woodcutting, the forests in Great Britain are getting diluted, So the Queen outlawed wood cutting. Moreover, Britain was adjusted free enterprise

Next, British Democracy encourages free enterprise. Britain wasn't really run from London.

The transportation system in Great Britain was pretty bad. And finally, island isolation provides political stability Great Britain avoided wars on Continental Europe and they hadn't been invaded for about 700 years. Therefore, there was a sense of security. So very briefly, that is the social context surrounding Great Britain and what allowed structural art to flourish in particular in Great Britain at that time. And the famous structural engineer of this era was Thomas Telford; born 1757, died 1834.

 THOMAS TELFORD  

 Thomas Telford; born 1757, died 1834. Now let's take a look at Thomas Telford's later works.

We started to look at the Craigellachie Bridge completed in 1814 spanning 150 feet.

Next, we're going to look at the Mythe Bridge completed in 1824 at about the same span, 170-foot span. And then finally the Menai Bridge completed in 1826. This is not an arch but is a 580 foot was a suspension bridge. With the design of the Craigellachie, Telford noticed that he made,

what he would call, essentially a mistake, and he corrected this with the Mythe Bridge.

Craigellachie Brigde, source: Google picture 

Mythee Bridge,  source: Google picture

If we look at these two bridges we see that the landscape is different

so you might notice they are different bridges by the landscape.

But if you look at just the bridge itself, can you notice the difference

between the two bridges? Because they are very similar to one another.

The difference between the Craigellachie Bridge and the Mythe Bridge is in the spandrels.

It's in those diagonal members that connect the deck to the arch.

If you look closely at those diagonal members you'll see that they're oriented differently

in the Craigellachie versus the Mythe.

In the Craigellachie, if you take the bisector of those diagonal pieces you'll see

that bisector is normal to the arch.

It's coming perpendicular to the arch.

Whereas in the Mythe Bridge the bisector of those diagonals is vertical.

It's completely straight up and down.

In the Mythe Bridge, this is a more efficient way of carrying the loads.

The loads in those diagonals are more efficiently or more evenly distributed

between those diagonal members, whereas in the Craigellachie Bridge

in particular, those diagonals that are leaning or more horizontal are carrying much less load

then the diagonals that are more vertical.

Now we come to the Menai Bridge completed in 1826,

a 580-foot span suspension bridge designed by Thomas Telford.

Now there was a need to design this bridge and the need arose from the active union of 1800

which merged the Kingdom of Ireland with the Kingdom of Great Britain.

They needed to connect London to Dublin and to do that you had to go through the Island

of Anglesey all the way to the tip of Holyhead.

And to get to Holyhead and even Anglesey you had to cross the Menai Straits.

If you look at the side spans of this bridge we see that it has both arches and suspenders.

And this again is ambiguous.

It doesn't tell you clearly how those loads are being carried.

But Telford did this because he was concerned about the wind.

He wanted to make sure the back stands were heavy and anchored.

Just before the bridge opened, Telford's resident engineer noticed undulations

from gusting winds so Telford added bracing, which cut down the movement.

Ten years later, about two years after Telford's death,

the bridge keeper reported large oscillations and unfortunately no action was taken

and in 1839 a gale tore part of the roadway loose.

Telford's writings in the 1820s and his resident engineer's field observations showed how

horizontal wind can cause extensive vertical motion in a suspension bridge.

Unfortunately, this lesson in history was lost in the bridge designs to come, as we will see.

In the Menai Bridge, although the towers look heavy, they're actually hollow,

like in the Pontcysyllte Aqueduct Bridge.

So Telford again is thinking about efficiency in his designs.

Let's use the Menai Bridge to define some terms for you as related to suspension bridges.

The first term that we have to understand is span.

When we talk about a span of a bridge we're talking about the longest unsupported length

and for suspension bridges, that distance is from one tower to the next.

Next, let's look at the cable.

The cable goes from anchor to tower, to the next tower, to the next anchor, and it is in tension.

And it's in tension due to the uniform loads imposed by the hanging suspenders.

The suspenders are the vertical elements that suspend, or support, the deck.

The form of that cable is parabolic.

I'm going to do a brief demonstration for you to show you the shape that these cables take

when loaded and it will give you a better sense for why the form

of a suspension bridge cable is parabolic.

In this demonstration, this chain represents the cable of a suspension bridge.

We know that the chain can only take tinsel forces.

It can't take any compression forces.

It could be stretched but it can't be squeezed.

So let's look at how the shape of this chain changes when we add loads.

So if I add one load right in the center we see the V shape that this chain takes.

But if I— Now, I'm going to add continuously load along this whole chain,

we're going to see it start to take the form of the cable

of a suspension bridge, which is a parabolic form.

Now you start to see the shape change a little bit more…

and more. So these weights represent essentially the load that's transferred from the suspender,

which is the vertical elements of a suspension bridge, to the cable.

And it's the load represented by the weight of the deck.

And we see that as I add more and more of these loads along the chain, we're starting to see

that parabolic form takes shape, which is the shape of the cable in a suspension bridge.

Telford designed his bridges for carriage loads but the railroad age was approaching

and that is where we move to next.

See you in the next Section guys :).
