Palu Tumbuh Ingkari Daya Dukungnya

Kruyt (1912) menulis, Palu adalah kota baru.
Kerentanan Kota Palu terhadap gempa bumi dan tsunami telah diketahui sejak 1970-an. Bahkan, J.A. Katili, doktor geologi pertama di Indonesia, yang pernah menjadi Dirjen Pertambangan, berulangkali mengingatkan soal ini. Namun dia tak berdaya menghadapi kemauan penguasa untuk menjadikan Palu sebagai pusat pertumbuhan di Sulteng. Palu terus tumbuh tanpa kendali, dan terutama menarik para pendatang dari berbagai daerah yang tidak mengenal riwayat bencana kota ini. Masyarakat Kaili yg telah mengenal taunami sebagai bombatalu, gempa sebagai linu, dan likuifaksi dengan istilah nalodo, semakin kecil porsinya di kota ini. Mereka kebanyakan tinggal di pedalaman, terutama di Sigi.
Kajian Gegar Prasetya (2001) yang telah dipublikasi di jurnal ilmiah internasional menunjukkan, perulangan tsunami di Selat Makassar hingga Palu mencapai 18 kali sejak 1800. Peta Sumber Gempa Nasional yang diluncurkan KemenPUPR tahun 2017 juga telah mencantumkan ancaman gempa daei sesar Palu Koro. Sedangkan peta kerentanan likuifaksi di Palu telah dibuat Badan Geologi pada tahun 2012. Hampir semua lokasi likuifaksi kali ini berada di zona kerentanan sangat tinggi yang telah dipetakan itu. Namun, kajian risiko ini kebanyakan ditutupi karena dianggap mengganggu investasi. Apa yang terjadi Palu menjadi cermin lemahnya kendali tata ruang dan rezim taya kota yang dikuasai logika ekonomi semata. Bagaimana dengan kota-kota yang lain? Sama saja. Lihat saja Jakarta. Daerah parkir air seperti situ dan rawa-rawa diuruk dan dijadikan perumahan, padahal jelas2 kota ini langganan banjir. Apakah ada yang tahu daerah-daerah yang ditinggali dulu bekas rawa-rawa yg tentu saja rawan likuifaksi kalau gempa? Jangan lupa, daerah-darrah reklamasi adalah zona empuk likuifaksi, seperti terjadi di Jepang saat gempa 2011.
#kita punya PR besar, bagaimana caranya pengetahuan lokal dan hasil kajian risiko bisa menyelamatkan nyawa?

Logic Analyzer with STM32 Boards

https://sysprogs.com/w/how-we-turned-8-popular-stm32-boards-into-powerful-logic-analyzers/ How We Turned 8 Popular STM32 Boards into Powerful Logic Analyzers March 23, 2017 Ivan Shcherbakov The idea of making a “soft logic analyzer” that will run on top of popular prototyping boards has been crossing my mind since we first got acquainted with the STM32 Discovery and Nucleo boards. The STM32 GPIO is blazingly fast and the built-in DMA controller looks powerful enough to handle high bandwidths. So having that in mind, we spent several months perfecting both software and firmware side and here is what we got in the end. Capturing the signals The main challenge when using a microcontroller like STM32 as a core of a logic analyzer is dealing with sampling irregularities. Unlike FPGA-based analyzers, the microcontroller has to share the same resources to load instructions from memory, read/write th...

The Difference Between LEGO MINDSTORMS EV3 Home Edition (#31313) and LEGO MINDSTORMS Education EV3 (#45544)

http://robotsquare.com/2013/11/25/difference-between-ev3-home-edition-and-education-ev3/ This article covers the difference between the LEGO MINDSTORMS EV3 Home Edition and LEGO MINDSTORMS Education EV3 products. Other articles in the ‘difference between’ series: * The difference and compatibility between EV3 and NXT ( link ) * The difference between NXT Home Edition and NXT Education products ( link ) One robotics platform, two targets The LEGO MINDSTORMS EV3 robotics platform has been developed for two different target audiences. We have home users (children and hobbyists) and educational users (students and teachers). LEGO has designed a base set for each group, as well as several add on sets. There isn’t a clear line between home users and educational users, though. It’s fine to use the Education set at home, and it’s fine to use the Home Edition set at school. This article aims to clarify the differences between the two product lines so you can decide which...

Building a portable GSM BTS using the Nuand bladeRF, Raspberry Pi and YateBTS (The Definitive and Step by Step Guide)

https://blog.strcpy.info/2016/04/21/building-a-portable-gsm-bts-using-bladerf-raspberry-and-yatebts-the-definitive-guide/ Building a portable GSM BTS using the Nuand bladeRF, Raspberry Pi and YateBTS (The Definitive and Step by Step Guide) I was always amazed when I read articles published by some hackers related to GSM technology. H owever , playing with GSM technologies was not cheap until the arrival of Software Defined Radios (SDRs), besides not being something easy to be implemented. A fter reading various articles related to GSM BTS, I noticed that there were a lot of inconsistent and or incomplete information related to the topic. From this, I decided to write this article, detailing and describing step by step the building process of a portable and operational GSM BTS. Before starting with the “hands on”, I would like to thank all the pioneering Hackers and Researchers who started the studies related to previously closed GSM technology. In part...
