Asam, Netral, Basa selain dilihat dari pengujian atau pengukuran dengan pH meter atau kunyit , juga bisa dibaca dari sinyal tanaman yang tumbuh di atasnya.

Setiap gulma punya kondisi tanah favoritnya sendiri.

Baca gulmanya. Baca lahannya.
Ada yang tahu?

Akhirnya ketemu juga ini instrumen.. namanya kemanak
Pertama kali denger buat ngiringin bedhaya ketawang dari kraton Surakarta, eh ternyata di Kraton Jogja juga adaaa

Kemanak itu salah satu alat musik tradisional khas Jawa yang biasanya dipakai di lingkungan Keraton gitu buat ngiringin tari-tarian sakral kek misalnya Tari Bedhaya dan Tari Srimpi. Bentuknya unik asli, bentuknya mirip pisang atau kelapa dibelah dua gitu, bahannya dari perunggu. Cara mainnya dipukul sampai keluar suara “tong-teng” gitu.

JALAN PINTAS TUBUH

1. *GUGUP?* Tahan napas selama 5 detik.
2. *CEMAS?* Letakkan tangan di dada + bernapaslah dengan perlahan.
3. *KURANG ENERGI?* Percikkan air dingin ke wajah.
4. *HIDUNG TERSUMBAT?* Gosokkan es batu pada langit-langit mulut.
5. *SUSAH TIDUR?* Berkedip dengan cepat selama 60 detik.
6. *MENINGKATKAN DAYA INGAT?* Kepalkan tanganmu kuat-kuat.
7. *SAKIT KEPALA?* Cubit bagian antara ibu jari dan telunjuk.
8. *MUAL?* Tekan pergelangan tangan bagian dalam dengan lembut.
9. *MENGANTUK?* Kunyah permen karet rasa mint.
10. *HILANG FOKUS?* Makan sesuatu yang renyah.

Tekanan darah tinggi itu bukan langsung bikin sakit… tapi diam-diam ngubah bentuk pembuluh darahmu.

Lihat video ini baik-baik :

Normal (<120/80)
Aliran darah masih lancar. Dinding pembuluh elastis, fleksibel, belum tertekan.

Mulai naik (120–139 / 80–89)
Belum terasa apa-apa. Tapi pembuluh darah sudah mulai bekerja lebih keras dari seharusnya.

Hipertensi (≥140/90)
Dinding pembuluh mulai menebal dan kaku. Aliran darah nggak lagi mulus. Organ mulai “terbebani”.

Hipertensi berat (≥180/120)
Ini sudah tahap berbahaya. Tekanan tinggi terus-menerus bisa merusak pembuluh dan organ vital.

Dan bagian paling menyeramkan adalah Diseksi arteri.
Dinding pembuluh robek, lalu terbentuk jalur darah “palsu”.
Aliran utama terganggu, dan ini bisa berujung fatal.

Banyak orang kecolongan karena
hipertensi sering tidak ada gejala.
Nggak pusing, nggak nyeri… tapi kerusakan tetap jalan, ada perubahan pelan-pelan yang terjadi di dalam tubuh.

tekanan darah kamu terakhir berapa?

[Ihtesham Ali @ihtesham2005]

A Persian scholar finished a single math book in 9th century Baghdad that quietly became the foundation for every line of code running on Earth today.

I started reading about him at midnight and could not believe how many things in my daily life trace back to one man.

His name was Muhammad ibn Musa al-Khwarizmi. The book is called The Compendious Book on Calculation by Completion and Balancing.

Every time you say the word algebra, you are saying his book title. Every time someone says the word algorithm, they are saying his name. Both English words come from him. Both are Latin transliterations of Arabic and of his own identity. The man did not just contribute to mathematics. He named it.

Here is the part almost nobody tells you.

Al-Khwarizmi was born around 780 CE in Khwarazm, in what is now Uzbekistan. He moved to Baghdad and worked at a research institution called the House of Wisdom, which during the Islamic Golden Age was the single most important center of learning on the planet. The caliph al-Mamun hired the best mathematicians, astronomers, and philosophers from across three continents and put them in one building with one job. Translate, study, and produce new knowledge.

Al-Khwarizmi finished his book on algebra around 820 CE. The Arabic title contained the word al-jabr, which referred to one of the two operations he used to solve equations. When the book was translated into Latin in the 12th century, the Latin world did not have a word for what he had built. So they kept his Arabic word. Al-jabr became algebra. The discipline was named after a single Arabic word in the title of a single book by a single man.

The deeper insight is what he actually changed about how humans think.

Before al-Khwarizmi, mathematical problems were solved geometrically. You drew shapes. You measured them. You compared areas. The Greeks had built an entire mathematical tradition on visual proofs and physical constructions. It was beautiful and limited. You could not solve a problem you could not draw.

Al-Khwarizmi did something nobody had done before him at this scale. He said you could solve any problem using abstract symbols and rules. You did not need a shape. You needed a procedure. You moved terms across the equation. You cancelled like terms on both sides. You isolated the unknown. He invented the idea that mathematics is a manipulation of symbols according to rules, not a study of physical figures.

That single shift made everything that came afterward possible. Calculus. Differential equations. Linear algebra. Quantum mechanics. None of it works if math is locked inside geometry. He pulled it out.

The second thing he did is the one that changed how the world counted forever. He took the Hindu numeral system from Indian mathematics, refined it, and wrote a book introducing it to the Arab world. That system included the concept of zero as a placeholder, and a positional notation where the value of a digit depends on its location. Roman numerals could not do complex calculation. Hindu-Arabic numerals could.

When his book on numerals was translated into Latin as Algoritmi de numero Indorum, the word Algoritmi was just the Latin spelling of his own name. Europeans started calling the new method "doing algorism," then "running an algorithm." The word for the most important concept in computer science is literally his name in Latin.

The third thing he did is the part that should haunt anyone who works in tech.

His method of solving problems was systematic. Step one, do this. Step two, check that. Step three, if condition A, then do X, otherwise do Y. He wrote down procedures that could be followed by anyone, anywhere, who knew how to read. The procedure did not depend on intuition or genius. It worked because the steps worked.

That is exactly what an algorithm is. A finite, deterministic procedure for solving a problem. He did not just give us the word. He gave us the entire concept of programming a thousand years before there was anything to program.

When Alan Turing built the first abstract model of computation in 1936, when John von Neumann designed the first stored-program computer in 1945, when every engineer at Google, OpenAI, Anthropic, and DeepMind writes code in 2026, they are working in a paradigm that started with one man in Baghdad twelve centuries ago.

The strangest part is what happens when you walk into any tech office in San Francisco or Bangalore or Lahore today. Engineers say the words algebra and algorithm hundreds of times a day. They do not know whose name they are saying. Almost nobody can spell al-Khwarizmi correctly on the first try.

His original Arabic manuscript is preserved at Oxford. His book on Hindu numerals survives only in Latin translation. The Latin version was the textbook that taught medieval Europe how to count.

The man who built the foundation of the AI revolution did not live to see a calculator. He died around 850 CE, a thousand years before the first electric current was sent through a wire. The civilization he built mathematics for collapsed. The library he wrote in burned. His own grave is unmarked.

But every algorithm running on every machine on Earth right now still answers to his name.
