Seperti rutinitas biasanya, hari ini saya berangkat nguli naik kereta dari kota Colmar ke kota Strasbourg, yang berjarak sekitar 75 KM. Kereta dari Colmar berangkat jam 07.37 pagi setiap harinya, dengan berhenti di kota Selestat, sekitar 10 menit dari Colmar. Beberapa menit setelah kereta kembali melaju ke kota tujuan, Strasbourg, tiba-tiba kereta memperlambat lajunya dan kemudian berhenti di sebuah stasiun kereta di kota Erstein, yang mana biasanya kereta tidak berhenti di stasiun kota kecil itu. Tentunya semua penumpang bertanya-tanya dan heran, ada apa dan apa yang menyebabkan kereta berhenti. Tidak beberapa lama, terdengar pengumuman melalui radio lokal yang terdapat di setiap gerbong kereta. Terdengar suara Kondektur kereta akan memberikan pengumuman dan informasi.

‘Malaikat’ yang menyaru
October 24, 2018Home Music Studio
May 12, 2018Liburan musim semi kemarin, saya mencoba membuat home music studio di rumah dengan memanfaatkan PC. Kebetulan di rumah ada beberapa peralatan musik seperti gitar, piano, launchpad dan drum. Karena saya mempunyai hobi musik, walaupun tidak profesional, sekedar untuk menghibur diri dan mengekspresikan mood. Mimpi punya real studio music belum terwujud… 🙂 Maka home music studio adalah solusi alternatif low cost yang dapat saya buat. Dengan berbekal sedikit effort dan skill ngoprek-ngoprek di mesin Linux, PC di rumah bisa disulap menjadi home music studio.

Good Habit for Great Coding
March 15, 2018
This e-book allows us to improving our programming skills with some examples in Python.
This e-book is about improving coding skills and learning how to write readable code. It is written both for teachers and developing programmers. But I must immediately tell you that we learn how to write computer code only by trying to code many challenging problems, reflecting on the experience, and remembering the lessons we learned. Hence, you will find here more than twenty quizzes and problems. Chess coach Willy Hendriks is right: There is no other way.

Protokol Routing RPL
January 23, 2018Internet of Things (IoT) bukan lagi sebagai fantasi sains-fiksi. Dengan kemajuan teknologi yang sangat pesat memungkinkan terhubungnya semua objek sehari-hari ke Internet. Namun, diperlukan sebuah solusi yang interoperabel untuk memastikan optimal komunikasi antar objek-objek tersebut. Protokol routing adalah salah satu elemen kunci pada IoT. Karena protokol routing memungkinkan setiap objek menentukan bagaimana mencapai objek lain. Beberapa kendala pada protokol routing antara lain saluran komunikasi yang tidak stabil dan energi daya rendah yang harus diperhitungkan dalam pengembangan protokol routing yang sesuai untuk IoT. Pada artikel kali ini, saya akan menyajikan sekilas tentang protokol RPL yang dirancang khusus untuk jaringan berdaya rendah dan lossy (Low-power and Lossy Network disingkat LLN).
Development of a New Routing Protocol by using Multi-objective and Swarm Intelligent Approaches for Wireless Sensor Network on Maritime Environment Monitoring
December 1, 2017This is the abstract for my International Research Collaboration and Scientific Publication with two French Institutions as international collaborators.
ABSTRACT
As the largest archipelago country in the world, Indonesia has great potential to be the world’s maritime axis. The maritime axis is a strategic idea which embodied to ensure inter-island connectivity, shipping and fishery industries development, marine transportation improvement and focus on maritime security. So maritime monitoring is crucial in order to prevent sea pollution, fish theft, sovereignty offenses, territorial disputes, and piracy. Nowadays, maritime monitoring has been a very interesting issue over the last decade. With the rapid advancement of technology and the Internet, sensor network technology has become very important in monitoring the aquatic environment. Maritime responsibilities, such as vigilance and patrolling, wildlife monitoring, and aqua-culture inspection, mostly require large operational teams and expensive equipment. In this research proposal, we will study a scalable robotics system based on swarm intelligence. We take advantage of bio-inspired artificial evolution approaches in order to synthesize scalable and robust collective behaviors for the nodes or the drones. In this research proposal, we will study and propose a system which composed of potentially hundreds sensor nodes or thousands of autonomous drones. Each drone could equipped with a number of different sensors. The use of numerous nodes or drones introduces redundancy in the system, which decreases the impact of hardware declines and has the potential to improve operational efficiency by admitting a wider area to be covered simultaneously. On the other hand, automating such missions greatly minimizes the maintenance cost while increasing scalability and availability. The behaviors of nodes or drones are then combined hierarchically, allowing the overall behavior for a particular mission to be quickly configured and tested in simulation. The goals of this research is to developing a new mechanism which enable swarm intelligence of nodes or drones to operate as a robust wireless sensor network (WSN) for maritime environment monitoring.
