Tentang Si Mumun

Si Mumun adalah mobil kesayangan yang pernah melengkapi awal-awal pembentukan keluargaku. Mobil yang mungil tapi hebat. Dia telah menemani perjalanan kami selama lebih kurang 8 tahun. Aku menuliskan sedikit catatan sentimentil tentangnya di sini (Bagian 1) dan sini (Bagian 2).

Excel: Our cherrie from "the market for lemon"

Meet our new family member. Her name is Excel, originally from Hyundai Excel. This is the evidence of our participation in 'the market for lemon'. Although we got her from such market, she is not a lemon instead she is a cherrie. Yes, indeed. She is quite a good and well conditioned used car, and we felt in love at the first time we saw her. And lately, she's already become important part of our daily routines in Canberra.

We consider Excel as cherrie due to several aspects that to some extent able to cope the problems of lemons market. First, the previous owner provide us with all information regarding Excel's past history. We know that she is the first hand car and regularly serviced in local authorized service center from her complete records, including service billing expenses. She also looks good in condition, started from external (paint colour, for example) as well as interior conditions (cleanliness on dashboard, door trim, etc).

Second, the previous owner also fair enough by revealing some of Excel's "unfortunate" conditions. Such conditions including some scratch in front bumper, broken handle at the back chair, and several minors. All of those problems definitely will not affecting Excel's performance and other can be solved by purchasing the parts at the service center. It is not necessarily to do very soon.

In respect to first and second reasons, Excel's previous owner succeed to diminish the asymmetrical information with respect to Excel quality. In this case, we certainly sure that Excel is not "perfectly" lemon. And since she is already become our family member, we will consider her as "Excel the cherrie". You are all welcome to ask for her ride when you have a chance.

Mobil vs. Bus vs. Sepeda

Sumber foto

Kalau Anda masih juga penasaran bagaimana kemacetan di Jakarta terjadi, foto di atas bisa memberikan gambaran sederhana tentang hal tersebut sekaligus solusinya. Silahkan klik di gambar untuk memperbesar.

Foto tersebut menggambarkan perbandingan luas jalan yang dibutuhkan untuk mengangkut jumlah orang yang sama (lihat sekumpulan orang yang diangkut) jika dihadapkan pada tiga pilihan moda transportasi: mobil, bus dan sepeda. Dari foto terlihat dengan jelas bahwa mobil memerlukan lebih banyak luas jalan untuk menampung jumlah orang yang sama. Diikuti sepeda dan yang paling efisien adalah bus. 

Jika para pemangku kepentingan dan pengambil kebijakan di DKI Jakarta melihat foto ini, dan ditambah kerelaan berpikir sedikit lebih panjang; maka tidak ada alasan lagi bagi mereka untuk tidak memprioritaskan sistem transportasi massal yang komprehensif untuk mengurangi kemacetan. Tapi entah kenapa mereka selalu mencari solusi pendek saja. 

Sayangnya, tidak ada foto perbandingan untuk moda transportasi angkot... Jadi penasaran, apakah jumlah angkot yang terus bertambah di kota Depok adalah solusi yang efektif untuk menekan kemacetan atau malah memperparah?? 

Ada yang berbisik, "Siapa peduli?!"
