The Dutch: We still have a room!
Holland, as one of the nominees in the big ten of countries
who has taken the most benefit from renewable energy sources for its electricity,
has installed instruments for producing alternative power everywhere in the
country. With the total of 41,543 square
kilometers, the country simply requires 800 square kilometers of solar panel
installed in order to cover the need of electricity. Since it is impossible to
create entirely free spaces for the panels, the Dutch play it smart by
installing some of them on buildings’ and houses’ roof, and even smarter that they
are trying to install the panels on the road. The project is piloted on a
cycling path.
But why a cycling path?
The fact that there is 113,018 kilometer of paved road and the
increasing numbers of people who prefer to ride bicycle, has encouraged cities
in the country to provide more lanes for the cyclists. One of the cycling paths
in Krommenie, a city in Northwest of Amsterdam, is having 1.5-2.5 cm of solar
panels installed on it. These solar panels are designed in such a way that they
can hold truck’s weight. It is estimated that the electricity obtained from the
sunrays at midday will be able to power streetlights, traffic lights, and even
houses nearby. The cycling path is chosen because bicycle will not cover the
entire streets even during a traffic jam.
Another creative idea has been applied in 2009, when an
organization called the Sustainable Dance Club produced the Sustainable Dance
Floor (SDF) and has it installed at a club and bar in Rotterdam called Watt. This
dance floor panel will produce kinetic energy which is stimulated by dancing
steps of the clubbers. A battery bar is projected on the wall which, according
to the club owner, is to show the clubbers the level of electricity they have
produced. Every person who dances energetically tend to produce 20 W, not so
much in contributing to the city, but enough to cut the power bill of the
building. On the same year, the variant of the floor, a single tile panel, was
installed at a paved road of Toulouse, France and the two-week trial resulted
in powering one street light which is derived from 8 panels.
In the future, I am picturing to have SDF installed in crowded
public places such as sidewalks, crossroads, or jogging tracks in order to obtain
bigger energy; or hopefully solar panels covering median of highways. Consideration
of budget should not limit the benefit in the long run, it is an infestation
and it is covering even more world problems, such as obesity, the decreasing of
fossil fuels comparing with the demands, air pollution, etc. Furthermore, the use of public
places will, as well, indirectly forced people to behave supportively other
than creating a big curiosity, for example, if SDF is installed at the jogging
track, jogging might become more attractive. The Dutch is right, there is
always a room for everything.

When Feeling Safety is Challenging
Baru-baru ini saya terlibat pembicaraan seru dengan generasi diatas
saya yang protes karena cucunya ikut field trip sekolah. Menurut beliau, field
trip adalah akal akalan guru sekolah yang mau traveling dengan gratis, karena biayanya
dibayar oleh orang tua murid.
Perdebatan ini dimenangkan oleh generasi diatas saya yang keukeuh dengan
pendapatnya. Membuat saya berpikir, kenapa bisa 'tidak perlu'?
Waktu saya kelas satu di sekolah dasar, setiap minggu orang tua saya
memberi saya uang 100 rupiah dan menyuruh saya untuk membeli jajanan tertentu
dikios sekolah, FYI, saat itu harga sebuah permen masih 25 IDR. Mungkin minggu
ini membeli 4 buah permen, minggu depan membeli permen dan chocoballs, tapi
selalu jumlahnya tidak boleh lebih dari 100 rupiah. Dengan cara ini saya
belajar untuk menghitung cepat, bahwa 4 koin 25 akan berjumlah 100, bila saya
menghabiskan dua kuarter saya akan punya 50 rupiah, dsb. Dikelas yang lebih
tinggi lagi tiap pagi sebelum sekolah saya disuruh pergi ke kios tetangga di blok
belakang rumah untuk membeli telur ayam yang jumlahnya berbeda beda setiap
harinya, saat itu saya belajar menambah data base GPS saya, belajar
berinteraksi dengan orang, beramah tamah dengan tetangga yang rumahnya saya
lewati, belajar memilih barang yang bagus untuk dibeli. Saat saya duduk di
bangku SMP, saya diberi uang untuk pulang sekolah naik angkot. Disitu saya
belajar untuk berani traveling sendirian, mengadvancekan GPS data base saya,
and meet more strangers. Apa arti semua
ini bila dibandingkan dengan situasi sekarang?
Sekarang bahkan salah satu field trip sekolah adalah berbelanja ke
supermarket, melihat sawah, atau memandikan kerbau. Menurut orang yang besar di
daerah, saya akan berpendapat sama dengan generasi diatas saya bahwa kegiatan
tersebut hanya membuang uang saja. Tapi, lihatlah kondisi Jakarta sekarang, berjalan kaki saja susah, hampir setiap kali
berjalan kaki saya berantem dengan pengendara sepeda motor karena menghalangi
jalan mereka. Padahal saya sudah
berjalan ditepi got. Selain itu ketakutan orang tua karena kasus penculikan
cukup sering terjadi, membuat orang tua bahkan tidak tega menyuruh anaknya
membeli permen di kios tetangga di ujung jalan.
Kondisi lain adalah bagi keluarga yang tinggal di gated community alias
komplek mewah yang ber-cluster-cluster, disana mana ada kios, kalau ingin
belanja ya harus diniatkan keluar rumah dengan menggunakan kendaraan pribadi. Maka
gak heran juga kalau pada akhirnya orang tua harus merelakan budget lebih untuk
field trip sekolah ke supermarket, agar anaknya bisa belajar berbelanja,
belajar memilih barang yang mau dibeli, dan berinteraksi dengan strangers.
Miris memang, saya belum terlalu tua, tapi kondisi disekeliling saya
berubah total dalam waktu 20 tahun. Hedonism dan paranoia makin tinggi, karena
crime, karena banyak orang lapar. padahal brain development dari dulu sampai
sekarang masih sama, harus “dirangsang.” Berbagai kemudahan teknologi membuat
orang semakin berpikir, “Ngapain susah-susah?” Ngapain susah-susah ke kios/toko,
kalau bisa belanja online? Ngapain susah-susah belajar berhitung, kalau ada
kalkulator di hape, di computer tablet, di laptop, bahkan di jam tangan?
Ngapain susah susah mengingat direction, kalau ada GPS yang tinggal tulis
keyword and press enter?
Mungkin jaman memang harus berubah, tapi saya percaya bahwa cara-cara
lama masih mungkin dilakukan bila semua orang mau bersusah susah. Pasti tantangannya lebih besar dari pada waktu
dulu, tapi tidak ada yang tidak mungkin. Atau mungkin kita yang tinggal di kota
harus berkaca dengan kehidupan di desa-desa yang lebih kurang masih sama dengan
keadaan waktu saya kecil diatas. Kenapa mereka masih bisa membiarkan anaknya ke
kios sendirian, masih bisa berjalan di tepi jalanan dengan tenang dan aman,
etc.

Should we avoid antibiotics in Jakarta? -- Opinion
Several days ago, my cousin told me about a group whose doctors are
againts prescribing antibiotics to their patients. This mailing list is initiated
by several pediatricians who think that antibiotic is harmful for children.
Talking about it in Jakarta context, where the air is heavily polluted and
hygiene is poor, water source is dirty, trashing is very well uncontrolled, and crowded living spaces;
antibiotic is believed to be necessary even for a single viral infection.
İn
western countries, nosocomial infection incidence are lower because the standard
of its hospitals are mostly satisfied regarding hygiene. However, in İndonesia, one shouldn't
generalize similar condition as a "should have been the same with".
İn hospitals in the US for example, even in government hospital you won't see
patients family members sleep over at the patient's room altogether. Thus, cross
contamination is less likely to happen. On the contrary, most government
hospitals patients in Indonesia would love to bring their family members along with them.
The more the merrier, even though the patient is unconcious, or even in coma
state, all family members would force themselves to come along and stay at the
hospital for the sake of togetherness until the patient is discharged. Since
they have poor financial situation, they cannot afford to rent a room at a
hotel or other places nearby. Thus, they'll usually sleep under patient's bed or at
ward corridor on the floor, giving it a hard time for the nurses and docs to reach the patient for regular examination.
Referring to that situation, as a medical doctor, would you consider to
risk you patients by not prescribing antibiotics as prophylaxis in the
treatment plan? İ wouldn't. İt is understood if unnecessary medication may lead
patients to other risk of drug resistants or allergy, however, you would not
prefer to risk your patients of having nosocomial infections or secondary infection, due to lack of
hygiene and cross contamination, either.
İn terms of ambulatory care, in addition, it is common to prescribe antibiotics
to almost every diagnosis in Puskesmas. Again it is because the health providers doubt the hygiene behavior at patients' house.
İt is not guaranteed that patients will generally be
avoided from secondary bacterial infection if doctor does not prescribe
antibiotics on every infectious disease he meets.
Perhaps, patients who came from middle to upper social class who are
believed to live in more hygienic environment would be okay without unnecessary antibiotic regimen in their prescription. These people, who are usually well educated, formally
and non formally, are more skeptical to any medical information/terms that they just heard of, and
cooperated well with doctor's instructions.
