Suara riuh di dalam hutan hujan antara lain: kicauan burung-burung, suara jangkrik, kelakar siamang. Tapi hampir selalu ada suara gergaji mesin para penebang liar sayup terdengar di kejauhan. Insinyur Topher White berbagi cara yang sederhana dan dapat dibuat secara massal untuk menghentikan penebangan yang membabi-buta ini -- yang dimulai dari ponsel bekas Anda.

Pada musim panas
tahun 2011, sebagai turis,
tahun 2011, sebagai turis,
00:25
I visited the rainforests of Borneo
for the very first time,
for the very first time,
2
13167
4426
untuk pertama kalinya saya mengunjungi
hutan hujan di pulau Kalimantan,
hutan hujan di pulau Kalimantan,
00:29
and as you might imagine,
3
17593
2048
dan seperti yang Anda kira,
00:31
it was the overwhelming sounds
of the forest that struck me the most.
of the forest that struck me the most.
4

riuh suara hutannya lah
yang paling mengejutkan saya.
yang paling mengejutkan saya.
00:36
There's this constant cacophony of noise.
5
24911
2810
Terdengar suara hiruk-pikuk
yang terus berbunyi.
yang terus berbunyi.
00:39
Some things actually do stick out.
6
27721
2415
Ada beberapa suara
yang terdengar menonjol.

00:42
For example, this here is a big bird,
a rhinoceros hornbill.

7
30136
4426
Misalnya, suara ini adalah suara burung
yang besar, burung rangkong badak.
yang besar, burung rangkong badak.
00:46
This buzzing is a cicada.
8
34562
4172
Bunyi dengung ini adalah suara jangkrik.
00:51
This is a family of gibbons.
9
39434
2613
Ini adalah sekawanan siamang.
Mereka bernyanyi ke satu sama
lain dari kejauhan.
lain dari kejauhan.
00:54
It's actually singing to each other
over a great distance.
over a great distance.
10
42047

00:59
The place where this was recorded
was in fact a gibbon reserve,
was in fact a gibbon reserve,
11
47341
2993
Tempat suara ini direkam adalah
kawasan suaka untuk siamang,
kawasan suaka untuk siamang,
01:02
which is why you can hear so many of them,
12
50334
2037
makanya suara mereka banyak terdengar,
01:04
but in fact the most important noise that
was coming out of the forest that time
was coming out of the forest that time
13
52372
4930
tetapi suara yang paling penting
yang berasal dari hutan waktu itu adalah
yang berasal dari hutan waktu itu adalah
01:09
was one that I didn't notice,
14
57302
1532
suara yang tidak saya sadari,
01:10
and in fact nobody there
had actually noticed it.
had actually noticed it.
15
58834
3109
dan bahkan tidak seorang pun
memperhatikan suara tersebut.
memperhatikan suara tersebut.
01:14
So, as I said, this was a gibbon reserve.
16
62373
1988
Ini adalah cagar alam untuk siamang.
01:16
They spend most of their time
rehabilitating gibbons,

17
64361
2809
Tugas utama mereka adalah
merehabilitasi siamang.

01:19
but they also have
to spend a lot of their time

Akan tetapi, kebanyakan
waktu mereka dihabiskan

19
69731

untuk mencegah penebangan liar
yang terjadi di hutan.
yang terjadi di hutan.
01:25
And so if we take the sound of the forest
20
73423
2043
Jika kita hilangkan suara-suara di hutan
01:27
and we actually turn down the gibbons,
the insects, and the rest,
the insects, and the rest,
21
75466
3557
lalu kita turunkan volume suara siamang,
serangga-serangga, dan lainnya,
serangga-serangga, dan lainnya,
01:31
in the background, the entire time,
in recordings you heard,
in recordings you heard,
22
79023
3666
ternyata ikut terekam
01:34
was the sound of a chainsaw
at great distance.
at great distance.
23
82689
3714
suara gergaji mesin di kejauhan.
01:38
They had three full-time guards
who were posted around this sanctuary

24
86403
3994
Ada tiga orang penjaga yang
ditempatkan di suaka ini

01:42
whose job was in fact
to guard against illegal logging,

25
90397

yang tugasnya khusus untuk
mencegah penebangan liar.
mencegah penebangan liar.
01:46
and one day, we went walking,
again as tourists, out into the forest,
again as tourists, out into the forest,
26
94599
3459
Lalu suatu hari, kami berjalan,
sebagai turis, masuk ke dalam hutan.
sebagai turis, masuk ke dalam hutan.
01:50
and within five minutes' walk,
27
98058
2253
Setelah lima menit berjalan,
01:52
we stumbled upon somebody
who was just sawing a tree down,
who was just sawing a tree down,
28
100311
3379
kami menjumpai beberapa orang
yang baru saja menebang pepohonan,
yang baru saja menebang pepohonan,
01:55
five minutes' walk, a few hundred meters
from the ranger station.
from the ranger station.
29
103690
3261
sekitar beberapa ratus meter
dari pos penjagaan hutan.
dari pos penjagaan hutan.
01:58
They hadn't been able
to hear the chainsaws,
to hear the chainsaws,
30
106951
2058
Mereka tak dapat mendengar
gergaji mesinnya.
gergaji mesinnya.
02:01
because as you heard,
the forest is very, very loud.
the forest is very, very loud.
31
109009
3817
Sebab, seperti yang Anda dengar,
hutannya sangatlah riuh ramai.
hutannya sangatlah riuh ramai.
02:04
It struck me as quite unacceptable
that in this modern time,
that in this modern time,
32
112826
3919
Yang tidak bisa diterima adalah
di masa modern seperti sekarang ini,
di masa modern seperti sekarang ini,
02:08
just a few hundred meters away
from a ranger station in a sanctuary,
from a ranger station in a sanctuary,
33
116745
4472
hanya beberapa ratus meter
dari pos penjaga suaka, di wilayah suaka,
dari pos penjaga suaka, di wilayah suaka,
02:13
that in fact nobody could hear it when
someone who has a chainsaw gets fired up.
someone who has a chainsaw gets fired up.
34
121217
3805
tak ada seorang pun yang mendengar ketika
seseorang menggunakan gergaji mesin.
seseorang menggunakan gergaji mesin.
02:17
It sounds impossible,
but in fact, it was quite true.
but in fact, it was quite true.
35
125022
4665
Seperti tak masuk akal,
tapi itulah yang terjadi.
tapi itulah yang terjadi.
02:21
So how do we stop illegal logging?
36
129689
1834
Bagaimana kita menghentikannya?
02:23
It's really tempting, as an engineer,
always to come up with a high-tech,
always to come up with a high-tech,
37
131523
3429
Sebagai seorang insinyur, saya
kerap terdorong untuk memunculkan solusi
kerap terdorong untuk memunculkan solusi
02:26
super-crazy high-tech solution,
38
134952
1761
berteknologi canggih yang gila,
02:28
but in fact, you're in the rainforest.
39
136713
1950
tapi sayangnya, ini hutan hujan tropis.
02:30
It has to be simple,
it has to be scalable,
it has to be scalable,
40
138663
2377
Solusinya harus mudah
dan bisa dibuat massal.
dan bisa dibuat massal.
02:33
and so what we also noticed
while were there was that
while were there was that
41
141040
3008
Selama kami di sana,
kami menemukan bahwa
kami menemukan bahwa
02:36
everything we needed was already there.
42
144048
2326
semua yang kami butuhkan ada di sana.
02:38
We could build a system
that would allow us to stop this
that would allow us to stop this
43
146374
2751
Kita bisa membangun sebuah sistem
yang bisa mencegahnya
yang bisa mencegahnya
02:41
using what's already there.
44
149125
2282
dengan menggunakan apa yang ada di sana.
02:43
Who was there? What was
already in the forest?
already in the forest?
45
151407
2232
Siapa dan apa yang ada di sana?
02:45
Well, we had people.
46
153639
1148
Kita punya orang-orang.
02:46
We had this group there that was
dedicated, three full-time guards,
dedicated, three full-time guards,
47
154787
3285
Kita punya kelompok tiga orang
yang bertugas untuk menjaga,
yang bertugas untuk menjaga,
02:50
that was dedicated to go and stop it,
48
158072
1774
dan mencegah penebangan liar.
02:51
but they just needed to know
what was happening out in the forest.
what was happening out in the forest.
49
159846
3114
Tapi mereka butuh sesuatu untuk tahu
yang terjadi di dalam hutan.
yang terjadi di dalam hutan.
02:54
The real surprise, this is the big one,
50
162960
1893
Yang mengejutkan,
dan ini cukup penting,
dan ini cukup penting,
02:56
was that there was connectivity
out in the forest.
out in the forest.
51
164853
2383
jaringan ponsel masuk
sampai ke dalam hutan.
sampai ke dalam hutan.
02:59
There was cell phone service
way out in the middle of nowhere.
way out in the middle of nowhere.
52
167236
2914
Jaringan ponsel sampai ke
tempat-tempat yang tak dihuni.
tempat-tempat yang tak dihuni.
03:02
We're talking hundreds of kilometers
from the nearest road,
from the nearest road,
53
170150
2931
Bahkan sampai beberapa ratus kilometer
dari jalanan terdekat.
dari jalanan terdekat.
03:05
there's certainly no electricity,
but they had very good cell phone service,
but they had very good cell phone service,
54
173081
3572
Sudah pasti tidak ada listrik,
tapi ada jaringan ponsel yang amat bagus.
tapi ada jaringan ponsel yang amat bagus.
03:08
these people in the towns
were on Facebook all the time,
were on Facebook all the time,
55
176653
2623
Penghuni sekitar hutan
sering memakai Facebook.
sering memakai Facebook.
03:11
they're surfing the web on their phones,
56
179276
1950
Mereka menjelajah internet lewat ponsel.
03:13
and this sort of got me thinking
that in fact it would be possible
that in fact it would be possible
57
181226
3109
Saya berpikir bahwa sangat memungkinkan
03:16
to use the sounds of the forest,
58
184335
2159
untuk memanfaatkan suara-suara dari hutan,
03:18
pick up the sounds
of chainsaws programmatically,
of chainsaws programmatically,
59
186494
2392
ambil suara gergaji mesinnya
dengan program,
dengan program,
03:20
because people can't hear them,
60
188886
1648
karena tidak bisa didengar orang,
03:22
and send an alert.
61
190534
1687
lalu mengirimkan peringatan.
03:24
But you have to have a device
to go up in the trees.
to go up in the trees.
62
192221
2582
Tapi kita harus punya alat
yang dipasang di atas pohon.
yang dipasang di atas pohon.
03:26
So if we can use some device
to listen to the sounds of the forest,
to listen to the sounds of the forest,
63
194803
3651
Jika kita punya alat untuk
menangkap suara riuh hutan,
menangkap suara riuh hutan,
03:30
connect to the cell phone
network that's there,
network that's there,
64
198454
2233
menghubungkannya ke
jaringan ponsel yang ada,
jaringan ponsel yang ada,
03:32
and send an alert to people on the ground,
65
200687
2034
lalu mengirim peringatan pada orang-orang,
03:34
perhaps we could have a solution
to this issue for them.
to this issue for them.
66
202721
3550
mungkin masalah ini bisa terselesaikan.
03:38
But let's take a moment
to talk about saving the rainforest,
to talk about saving the rainforest,
67
206271
3280
Mari sejenak kita berbicara
tentang perlindungan hutan hujan.
tentang perlindungan hutan hujan.
03:41
because it's something that we've
definitely all heard about forever.
definitely all heard about forever.
68
209551
3842
Kita sudah sering mendengar hal ini
didengungkan di mana-mana.
didengungkan di mana-mana.
03:45
People in my generation
have heard about saving the rainforest
have heard about saving the rainforest
69
213393
2919
Generasi saya kerap mendengar pesan
tentang perlindungan hutan
tentang perlindungan hutan
03:48
since we were kids,
70
216312
1900
sejak kami kecil.
03:50
and it seems that the message
has never changed:
has never changed:
71
218212
2248
Dan, pesannya tidak pernah berubah:
03:52
We've got to save the rainforest,
it's super urgent,
it's super urgent,
72
220460
2522
Kita harus lindungi hutan,
ini perlu diutamakan.
ini perlu diutamakan.
03:54
this many football fields
have been destroyed yesterday.
have been destroyed yesterday.
73
222982
2706
Area seluas beberapa lapangan bola
sudah hancur kemarin.
sudah hancur kemarin.
03:57
and yet here we are today,
about half of the rainforest remains,
about half of the rainforest remains,
74
225688
3304
Dan saat ini, hanya sekitar separuh
hutan hujan yang tersisa.
hutan hujan yang tersisa.
04:00
and we have potentially more urgent
problems like climate change.
problems like climate change.
75
228992
4327
Kita juga dihadapkan pada perubahan iklim
yang bisa menjadi permasalahan besar.
yang bisa menjadi permasalahan besar.
04:05
But in fact, this is the little-known fact
that I didn't realize at the time:
that I didn't realize at the time:
76
233319
3909
Ada fakta yang tidak saya
ketahui ketika itu:
ketahui ketika itu:
04:09
Deforestation accounts
for more greenhouse gas
for more greenhouse gas
77
237228
2961
Penebangan hutan menghasilkan
gas rumah kaca lebih banyak
gas rumah kaca lebih banyak
04:12
than all of the world's planes,
trains, cars, trucks and ships combined.
trains, cars, trucks and ships combined.
78
240189
4040
dari pesawat, kereta, mobil, truk,
dan kapal di seluruh dunia.
dan kapal di seluruh dunia.
04:16
It's the second highest contributor
to climate change.
to climate change.
79
244229
2716
Ini adalah kontributor
perubahan iklim tertinggi kedua.
perubahan iklim tertinggi kedua.
04:18
Also, according to Interpol,
80
246945
2833
Juga, disebutkan oleh Interpol,
04:21
as much as 90 percent of the logging
that takes place in the rainforest
that takes place in the rainforest
81
249778
3529
sebanyak 90 persen penebangan
yang terjadi di hutan hujan tropis
yang terjadi di hutan hujan tropis
04:25
is illegal logging,
like the illegal logging that we saw.
like the illegal logging that we saw.
82
253307
3781
adalah penebangan liar, seperti
yang tadi kita saksikan.
yang tadi kita saksikan.
04:29
So if we can help people in the forest
enforce the rules that are there,
enforce the rules that are there,
83
257088
4044
Maka, jika kita membantu orang-orang
di hutan untuk menegakkan aturan di sana,
di hutan untuk menegakkan aturan di sana,
04:33
then in fact we could eat heavily
into this 17 percent
into this 17 percent
84
261132
3924
kita bisa mengurangi yang 17 persen ini,
04:37
and potentially have a major impact
in the short term.
in the short term.
85
265056
2611
dan bisa berdampak sangat baik
dalam jangka pendek.
dalam jangka pendek.
04:39
It might just be the cheapest,
fastest way to fight climate change.
fastest way to fight climate change.
86
267667
5165
Ini bisa jadi cara paling murah dan cepat
untuk mengatasi perubahan iklim.
untuk mengatasi perubahan iklim.
04:44
And so here's the system that we imagine.
87
272832
1998
Ini sistem yang kami bayangkan.
04:46
It looks super high tech.
88
274830
1194
Terlihat canggih.
04:48
The moment a sound of a chainsaw
is heard in the forest,
is heard in the forest,
89
276024
2633
Pada saat terdengar suara
gergaji mesin dari hutan,
gergaji mesin dari hutan,
04:50
the device picks up the sound
of the chainsaw,
of the chainsaw,
90
278657
2172
alat ini mengambil suara gergaji itu,
04:52
it sends an alert through the standard
GSM network that's already there
GSM network that's already there
91
280829
3607
lalu mengirimkan peringatan melalui
jaringan GSM standar yang tersedia
jaringan GSM standar yang tersedia
04:56
to a ranger in the field
92
284436
2087
ke penjaga hutan yang bertugas di lapangan
04:58
who can in fact show up in real time
and stop the logging.
and stop the logging.
93
286523
2817
yang bisa langsung menghentikan
penebangan tersebut.
penebangan tersebut.
05:01
It's no more about going out
and finding a tree that's been cut.
and finding a tree that's been cut.
94
289340
3909
Ini bukan lagi tiba di lokasi dan
menemukan pepohonan yang sudah ditebang.
menemukan pepohonan yang sudah ditebang.
05:05
It's not about seeing
a tree from a satellite
a tree from a satellite
95
293249
2176
Bukan lagi melihat area yang sudah
dibabat habis
dibabat habis
05:07
in an area that's been clear cut,
96
295425
1636
melewati satelit,
05:09
it's about real-time intervention.
97
297061
2198
ini tentang mencegah pada saat
penebangan langsung.
penebangan langsung.
05:11
So I said it was the cheapest
and fastest way to do it,
and fastest way to do it,
98
299669
2721
Kenapa saya bilang cara ini paling murah
dan cepat,
dan cepat,
05:14
but in fact, actually, as you saw,
they weren't able to do it,
they weren't able to do it,
99
302390
2925
padahal mereka belum berhasil
melakukannya,
melakukannya,
05:17
so it may not be so cheap and fast.
100
305315
1884
jadi mungkin tidak terlalu
murah dan cepat.
murah dan cepat.
05:19
But if the devices in the trees
were actually cell phones,
were actually cell phones,
101
307199
3436
Tapi jika perangkat yang kita tempatkan
di pepohonan adalah ponsel,
di pepohonan adalah ponsel,
05:22
it could be pretty cheap.
102
310635
1556
solusi ini bisa tergolong murah.
05:24
Cell phones are thrown away
by the hundreds of millions every year,
by the hundreds of millions every year,
103
312191
4287
Ponsel banyak dibuang oleh
ratusan juta orang tiap tahunnya.
ratusan juta orang tiap tahunnya.
05:28
hundreds of millions in the U.S. alone,
104
316478
2121
Ratusan juta orang tersebut
hanya di AS saja.
hanya di AS saja.
05:30
not counting the rest of the world,
which of course we should do,
which of course we should do,
105
318599
3181
Kita belum menghitung yang lainnya,
yang juga perlu kita hitung.
yang juga perlu kita hitung.
05:33
but in fact, cell phones are great.
106
321780
2531
Jadi, ponsel itu sangat hebat.
05:36
They're full of sensors.
107
324311
1333
Banyak sensor di dalamnya.
05:37
They can listen
to the sounds of the forest.
to the sounds of the forest.
108
325644
2152
Ia dapat merekam suara dari dalam hutan.
05:39
We do have to protect them.
109
327796
1382
Kita memang harus menjaganya.
05:41
We have to put them in this box
that you see here,
that you see here,
110
329178
2407
Kita harus letakkan di dalam
kotak seperti ini
kotak seperti ini
05:43
and we do have to power them.
111
331585
1567
dan perlu dinyalakan.
05:45
Powering them is one of the greater
engineering challenges
engineering challenges
112
333152
2763
Sumber dayanya jadi salah satu
tantangan teknis terbesar
tantangan teknis terbesar
05:47
that we had to deal with,
113
335915
1300
yang harus kita hadapi,
05:49
because powering a cell phone
under a tree canopy,
under a tree canopy,
114
337215
2752
Sebab, menyalakan sebuah ponsel
di bawah kanopi pohon,
di bawah kanopi pohon,
05:51
any sort of solar power
under a tree canopy,
under a tree canopy,
115
339967
2252
dengan tenaga surya
di bawah kanopi pohon,
di bawah kanopi pohon,
05:54
was an as-yet-unsolved problem,
116
342219
1810
adalah masalah yang belum terpecahkan.
05:56
and that's this unique

Ini adalah kepingan-kepingan
yang sudah dipotong.
yang sudah dipotong.
06:05
So this is me putting it all together
120
353829
3506
Ini saya, ketika sedang menyatukannya
06:09
in my parents' garage, actually.
121
357335
1881
di garasi orang tua saya.
06:11
Thanks very much to them
for allowing me to do that.
for allowing me to do that.
122
359216
2577
Berkat mereka saya bisa melakukan ini.
06:13
As you can see,
this is a device up in a tree.

06:18
What you can see from here, perhaps,
is that they are pretty well obscured

124

Jika diamati, perangkat
tersebut cukup tersamarkan

06:21
up in the tree canopy at a distance.
125
369734
1802
di kanopi pohon dari kejauhan.
06:23
That's important, because although
they are able to hear chainsaw noises
they are able to hear chainsaw noises
126
371536
3477
Ini penting, karena meski alat ini bisa
mendengar suara gergaji mesin
mendengar suara gergaji mesin
06:27
up to a kilometer in the distance,

dari sejauh satu kilometer,

about three square kilometers,

sehingga melingkupi luas area
kira-kira 3 km persegi,

06:31
if someone were to take them,
it would make the area unprotected.

129
379303
3178
jika seseorang mengambilnya,
area itu jadi tidak terlindungi lagi.
area itu jadi tidak terlindungi lagi.
06:35
So does it actually work?
130
383281
2753
Jadi, apakah perangkat ini bekerja?
06:38
Well, to test it,
we took it back to Indonesia,
we took it back to Indonesia,
131
386034
2972
Untuk mengujinya,
kami kembali ke Indonesia.
kami kembali ke Indonesia.
06:41
not the same place, but another place,
132
389006
2113
Bukan di tempat yang sama,
tapi di tempat lain
tapi di tempat lain
06:43
to another gibbon reserve
133
391119
1671
suaka margasatwa untuk siamang juga
06:44
that was threatened daily
by illegal logging.

134
392790
2845
yang setiap harinya terancam
dengan adanya penebangan liar.

06:48
On the very second day, it picked up
illegal chainsaw noises.
illegal chainsaw noises.
135
396505
3919
Di hari kedua, alat ini menangkap
suara gergaji mesin ilegal.
suara gergaji mesin ilegal.
06:52
We were able to get a real-time alert.
136
400424
2199
Kami dapat peringatan langsung saat itu
06:54
I got an email on my phone.
137
402623
1347
dari surel yang masuk ke ponsel saya.
06:55
Actually, we had just climbed the tree.
Everyone had just gotten back down.
Everyone had just gotten back down.
138
403970
3716
Saat itu kami baru saja memanjat pohon itu
dan baru kembali dari sana.
dan baru kembali dari sana.
06:59
All these guys are smoking cigarettes,
139
407686
2240
Ketika itu orang-orang sedang merokok,
07:01
and then I get an email,
and they all quiet down,
and they all quiet down,
140
409926
2857
lalu saya mendapat surel dan
semua terdiam.
semua terdiam.
07:04
and in fact you can hear the chainsaw
141
412783
2104
Lalu terdengarlah suara gergaji mesin
07:06
really, really faint in the background,
142
414887
1929
amat sangat sayup dari kejauhan.
07:08
but no one had noticed it
until that moment.
until that moment.
143
416816
2305
Tak seorang pun memperhatikannya
sebelumnya.
sebelumnya.
07:11
And so then we took off
to actually stop these loggers.
to actually stop these loggers.
144
419121
3274
Lalu kami pergi untuk menghentikan
para penebang ini.
para penebang ini.
07:14
I was pretty nervous.
145
422395
1509
Saya sangat gugup ketika itu.
07:15
This is the moment where we've actually
arrived close to where the loggers are.
arrived close to where the loggers are.
146
423904
4226
Ini saat kami berada sangat dekat
dengan para penebang.
dengan para penebang.
07:20
This is the moment where you can see
where I'm actually regretting
where I'm actually regretting
147
428130
3114
Ini saat saya menyesali,
07:23
perhaps the entire endeavor.
148
431244
2001
mungkin, keseluruhan kerja keras kami ini.
07:25
I'm not really sure what's on
the other side of this hill.
the other side of this hill.
149
433245
2743
Saya tidak yakin apa yang terjadi
di balik bukit ini.
di balik bukit ini.
07:27
That guy's much braver than I am.
150
435988
1963
Orang itu jauh lebih berani dari saya.
07:29
But he went, so I had to go, walking up,
151
437951
4180
Dia terus jalan, jadi saya harus
mengikutinya ke atas,
mengikutinya ke atas,
07:34
and in fact, he made it over the hill,
152
442131
2159
dan dia sudah sampai di puncak bukit
07:36
and interrupted the loggers in the act.
153
444290
3237
dan menghentikan para penebang.
07:39
For them, it was such a surprise --
154
447527
1662
Bagi mereka, sungguh mengejutkan --
07:41
they had never, ever
been interrupted before --
been interrupted before --
155
449189
2380
belum pernah sekalipun mereka ketahuan --
07:43
that it was such an impressive
event for them,
event for them,
156
451569
2165
jadi saat itu mereka benar-benar kaget
dan kami dengar mereka tidak pernah
kembali lagi sejak itu.
kembali lagi sejak itu.
07:45
that we've heard from our partners
they have not been back since.
they have not been back since.
157
453734
3116
Mereka itu sebenarnya hebat.
07:48
They were, in fact, great guys.
158
456850
1492
Mereka menunjukkan bagaimana
mereka beroperasi,
mereka beroperasi,
07:50
They showed us how
the entire operation works,
the entire operation works,
159
458342
2180
dan mereka meyakinkan kami saat itu bahwa
07:52
and what they really convinced us
on the spot was that
on the spot was that
160
460522
2574
jika kita bisa menangkap basah dan
menghentikan mereka beraksi,
menghentikan mereka beraksi,
07:55
if you can show up
in real time and stop people,
in real time and stop people,
161
463096
2245
07:57
it's enough of a deterrent
they won't come back.
they won't come back.
162
465341
4182
itu sudah cukup untuk mencegah mereka
kembali.
kembali.
08:01
So --
163
469529
1556
Maka --
08:03
Thank you. (Applause)
164
471085
4991
Terima kasih. (Tepuk tangan)
08:09
Word of this spread, possibly
because we told a lot of people,
because we told a lot of people,
165
477586
3854
Cara ini sudah tersebar, mungkin, karena
kami sampaikan ke banyak orang.
kami sampaikan ke banyak orang.
08:13
and in fact, then some really
amazing stuff started to happen.
amazing stuff started to happen.
166
481440
3437
Lalu ada hal-hal menarik yang terjadi.
08:16
People from around the world
started to send us emails, phone calls.
started to send us emails, phone calls.
167
484877
3669
Orang-orang di seluruh dunia mulai
mengirimi kami surel dan menelepon kami.
mengirimi kami surel dan menelepon kami.
08:20
What we saw was that people
throughout Asia,
throughout Asia,
168
488546
2089
Orang-orang dari seluruh Asia,
08:22
people throughout Africa,
people throughout South America,
people throughout South America,
169
490635
2742
seluruh Afrika, seluruh Amerika Selatan,
08:25
they told us that they could use it too,
170
493377
1911
mereka bilang mereka juga membutuhkannya.
08:27
and what's most important,
171
495288
1280
Dan yang paling penting,
08:28
what we'd found that
we thought might be exceptional,
we thought might be exceptional,
172
496568
2498
apa yang kami anggap mengagumkan adalah
08:31
in the forest there was
pretty good cell phone service.
pretty good cell phone service.
173
499066
2582
di dalam hutan ada koneksi jaringan ponsel
yang cukup baik.
yang cukup baik.
08:33
That was not exceptional, we were told,
174
501648
1877
Hal itu biasa saja, katanya,
08:35
and that particularly is on the periphery
of the forests that are most under threat.
of the forests that are most under threat.
175
503525
3943
dan itu ada di pinggiran hutan yang
areanya paling terancam.
areanya paling terancam.
08:39
And then something
really amazing happened,
really amazing happened,
176
507468
2300
Lalu hal yang sangat mengagumkan terjadi,
08:41
which was that people started sending us
their own old cell phones.
their own old cell phones.
177
509768
3483
yaitu ketika orang-orang mulai
mendonasikan ponsel bekas mereka.
mendonasikan ponsel bekas mereka.
08:45
So in fact what we have now is a system
178
513251
1950
Yang kami punya sekarang adalah sistem
08:47
where we can use people on the ground,
people who are already there,
people who are already there,
179
515201
3343
yang memanfaatkan orang
yang sudah ada di lapangan,
yang sudah ada di lapangan,
08:50
who can both improve
and use the existing connectivity,
and use the existing connectivity,
180
518544
3065
yang bisa meningkatkan dan menggunakan
sambungan yang ada,
sambungan yang ada,
dan kami menggunakan ponsel bekas
yang dikirimkan pada kami
yang dikirimkan pada kami
08:53
and we're using old cell phones
that are being sent to us
that are being sent to us
181
521609
2677
08:56
by people from around the world
182
524286
1493
dari berbagai belahan dunia
08:57
that want their phones to be doing
something else in their afterlife,
something else in their afterlife,
183
525779
3293
yang ingin memanfaatkan
ponsel bekas mereka
ponsel bekas mereka
yang sudah tidak dipakai lagi.
09:01
so to speak.
184
529072
754
09:01
And if the rest of the device
can be completely recycled,
can be completely recycled,
185
529826
2929
Jika bagian ponsel yang lain
bisa didaur ulang,
bisa didaur ulang,
09:04
then we believe it's
an entirely upcycled device.
an entirely upcycled device.
186
532755
2716
maka ini adalah
alat hasil daur ulang total.
alat hasil daur ulang total.
09:07
So again, this didn't come
because of any sort of high-tech solution.
because of any sort of high-tech solution.
187
535471
3654
Lagi-lagi, ini bukan solusi
berteknologi tinggi.
berteknologi tinggi.
09:11
It just came from using
what's already there,
what's already there,
188
539125
2313
Ini hanya menggunakan
hal-hal yang sudah ada,
hal-hal yang sudah ada,
09:13
and I'm thoroughly convinced
that if it's not phones,
that if it's not phones,
189
541438
2856
dan saya yakin kalau bukan dengan ponsel,
09:16
that there's always
going to be enough there
going to be enough there
190
544294
2369
pasti ada hal lain dalam jumlah yang cukup
09:18
that you can build similar solutions
191
546663
1811
yang bisa membuat solusi yang sama
09:20
that can be very effective
in new contexts.
in new contexts.
192
548474
2066
dan efektif dalam konteks yang baru.
09:22
Thank you very much.
193
550540
2136
Terima kasih banyak.

ABOUT THE SPEAKER
Topher White - Conservation technologistThrough his startup Rainforest Connection, Topher White transforms used cell phones into guardians of the rainforest.
Why you should listen
In 2012, Topher White founded Rainforest Connection, a startup which converts recycled cell-phones into solar-powered listening devices to monitor and protect remote areas of the rainforest. Now an established NGO, Rainforest Connection has helped stop illegal logging and poaching operations in Sumatra, and the system is being expanded to three more rainforest reserves in Indonesia, the Amazon and Africa.
With a background in physics and engineering, White worked as web chief of ITER and co-founded Enthuse, a sports engagement and mobile rewards platform. For Rainforest Connection, he’s fashioned a simple device made of discarded cell phones and solar panels that detects and sends alerts when it picks up the sound of chainsaws in protected rainforests, allowing for intervention in real time.
