Trend of Mobility Changes due to Pandemic

Tableau Dashboard of Mobility Changes

How Indonesians are moving around differently due to COVID-19 Pandemic? How their mobility trends changed for trip to workplaces, groceries and pharmacy, restaurants, parks, transit stations, or just staying at home?

Well, under the #covid19 pandemic, it’s time for us to work from home, study from home and worship at home. That advice was announced by Pak Jokowi for Indonesians (esp. Jabodetabek) on March 15, 2020. Look at this ‘spaghetti’ graph with the data sourced from Google Community Mobility Report below. Start from 15 March 2020, around +15% mobility trend changes for places of residences. (Note: mobility changes means two parameters how visits and length of stay at the places.) Around -15% mobility trend changes for places of work.

Bagaimana Pola Perubahan Mobilitas Masyarakat sebelum dan selama Pandemi COVID-19?

Beberapa hari lagi, tepatnya tanggal 24 April 2020, saya akan membawakan materi di webinar IYKRA. Temanya adalah Analisis Perubahan Mobilitas Masyarakat selama Pandemi COVID-19.

Berdasarkan Data PHEOC Kemkes, per 13 April 2020 Indonesia sudah tercatat sedikitnya 4.557 kasus terkonfirmasi COVID-19 dengan 399 kasus meninggal dan 380 kasus sembuh. Diperkirakan akan tetap naik lagi dari hari ke hari. Ada yang memprediksi eksponensial seperti di Amerika Serikat, atau Sigmoid seperti di Tiongkok.

A Start Guide to Play with Data

Start Guide to play with Data

A year ago, I was asked by one of my leader to convince him why a data scientist must use a high-end laptops. It is not a difficult answer if you have been working with data for about 1-3 months with a low-end spec laptop.

Well, the biggest painful work for data scientist is about data preparation, and it costs a lot of memory and storage.

What if your data big? What if you want to create an excel file with hundred thousands of row? What if you need to install softwares that are restricted by the IT team?

You need a workstation or a laptop with at least 16GB RAM and 1 TB Storage.
While, still … you still need a server!

Here the detail is. I sent this slide to my leader. He then provide me with the laptop that I need.

Just in case you need the similar justification, please download my slide here: A Start Guide to Play with Data.

Sharing Mobility Data Insights at Tech In Asia Conference 2018 Jakarta

You may see my previous post on this link: “Menimba ilmu di Tech in Asia (TIA) PDC 2017“. I didn’t actively contribute at that time. I just became an audience. Became someone who just listened to what speakers trying to provide.

But the day came, one year after, on October 24, 2018. I was trusted to become one of the speakers. I gave big Thanks to my leader: Mia Melinda, who trusted me to become a TIA speaker. The speaker means someone who give values to others. Someone who have to be responsible to not wasting 30 mins time of the super-busy audience. The audience who had spent time and money more than 1 mio rupiahs for just entering this 2 days-event.
