Screen capture from the eFishery data team sharing session. Pardon my quirky smile.

Last week, a friend of mine invited me to share my experience as a data analyst to his team in eFishery, an Indonesian aquaculture start-up. During the session, I talked about becoming a business-minded data analyst. In summary, I introduce an alternative perspective where we have to put ourselves in the business user’s shoes. Since the content is similar to my post back in 2017, I am not going to reiterate the idea again.

What I want to discuss is what happened by the end. …


Sesame Streets and the Transformers are not threats to humanity

Anyone who try to catch up with the world of Natural Language Processing (NLP) may notice something strange. The researchers in the field casually borrowed Sesame Street characters, such as Bert and Elmo, and put them side-by-side to an image of Optimus Prime. What is happening here?

In NLP, BERT is an abbreviation for Bidirectional Encoder Representations from Transformers. What was that? Do not worry, we will get back to that. And ELMo? Embeddings from Language Models. I agree those names sound like unnatural concepts. To be honest, I am not even sure why NLP uses Sesame Street’s character names…

Attention heatmap for a sample news sentence, higher value means more attention.

About a month ago, I felt the need to refresh my memory on PyTorch. At the same time, I wanted to learn more about the recent development in Named Entity Recognition (NER), mainly because the topic is related to my thesis. Strangely, I could not find any comprehensive tutorial. Some tutorials are just an introduction to how PyTorch works in general, which was too simple. Other tutorials contain walls of code, trying to implement every technique that has seen the light of day. If there were something in between, they mixed PyTorch with Keras, rather than using Torchtext (I demand…

As of June 1, 2020, Tokopedia amass 4.8 average ratings on the iOS app store

In March 2020, a hacker claimed to have successfully collected a staggering 91 million user data from Indonesia’s e-commerce giant, Tokopedia. The previous year, its competitor, Bukalapak, experienced a similar affair. However, in both cases, users’ trust seems unaffected. The reason can be because the users are unaware of those misconducts or the potential harm of the breach. I bring forward the ethical issue of companies’ tendency to exploit users’ trust. Are we trusting them too blindly?

Following the news, Tokopedia stated that customers are safe and urged them to update their passwords. That can be true if usernames and…


It was 8.30am and the cold fall gust of the Netherlands was hitting us like there is no tomorrow. That day was such a crucial time for us, because finally, after sending a bunch of emails (i.e. spamming) many hospitals, we received a reply from a willing Hospital Pharmacist (HP) for an interview. We biked through the city of Den Bosch and reached a nearby hospital around 8.50am for a meeting scheduled at 9am. Our excitement was hitting the roof when we were standing in front of the automatic door of the hospital. …

“Who is an entrepreneur? Someone who jumps off a cliff and builds a plane on the way down.”

Reid Hoffman — Founder of LinkedIn

In the era of fast-changing markets and constant technological disruptions, those who do not innovate will become extinct. Innovation has been a central theme and at the heart of it are the entrepreneurs. Brave minds who dare not only to dream of a better world, but also willing to go face-to-face with the challenges. …

data is the new oil

Tidak perlu lagi menyebutkan angka-angka yang mencengangkan mengenai pertumbuhan volume data karena Anda pasti sudah sering mendengar atau membacanya. Mirip dengan minyak bumi yang menjadi primadona perusahaan energi pada masanya, saat ini data ditambang oleh berbagai perusahaan teknologi dan menjadi sumber penghasilan. Selain Gross Domestic Product, ada kepanjangan GDP yang menjadi tolok ukur produktivitas suatu negara memiliki kepanjangan baru: Gross Data Product. Sudah menjadi rahasia umum bahwa negara yang bisa menguasai pengelolaan data adalah calon pemimpin perkembangan ekonomi di masa depan.

Selama tahun 2018, keamanan data pribadi menjadi tema yang gencar diperbincangkan di dunia. Secara…


Media sosial telah menjadi bagian yang tidak bisa ditinggalkan ketika kita berjalan-jalan. Entah tertera di hukum yang mana, kita seolah diwajibkan untuk membagi pengalaman kehidupan melalui akun Instagram. Terusik dengan peran media sosial yang begitu dominan, saya sendiri mencoba memikirkan ulang apa sebenarnya tujuan saya berjalan-jalan? Apakah Instagram mendukung tujuan tersebut atau justru mengalihkan saya pada hal lain yang bukan prioritas?

Pemikiran mengenai dokumentasi dalam perjalanan mulai menghantui saya sejak pendakian Kawah Ijen pada tahun 2016. Ketika berada di puncak setelah 4 jam pendakian, saya justru sibuk mengambil gambar hingga kehilangan waktu untuk bisa menikmati momen sepenuhnya. …

I’d like to share a revelation that I’ve had during my time here. It came to me when I tried to classify your species and I realized that you’re not actually mammals. Every mammal on this planet instinctively develops a natural equilibrium with the surrounding environment but you humans do not. You move to an area and you multiply and multiply until every natural resource is consumed and the only way you can survive is to spread to another area. There is another organism on this planet that follows the same pattern. Do you know what it is? A virus…

Ilmu bisnis bagi saya adalah perkara pengalaman dan jaringan. Selain itu, faktor eksternal seperti keberuntungan juga menentukan keberhasilan bisnis. Tidak ada rumusnya, semua tergantung niat dan nyali (dan modal).

Setelah mulai membaca diskusi pada ranah akademik bisnis, saya mulai menyadari bahwa bidang ini juga memiliki teori dan formulasi yang menarik. Ada fokus studi yang berusaha menstrukturkan hal yang terlihat begitu tidak beraturan. Hal pertama yang ingin saya bicarakan adalah mengenai strategi bisnis secara umum.

Pada dasarnya, strategi bisnis hanya ada 2 macam: harga atau diferensiasi. [1]

Harga

Mengejar harga murah artinya perusahaan berusaha menekan biaya sekecil mungkin untuk setiap peserta pasar…
