  "Sintesis nanopartikel emas berselubung 3-MPA. Untuk biosensor plasmonik," itulah yang tertulis pada halaman pertama slide presentasi di pagi ini. Tulisannya terlihat cukup jelas, meskipun aku hanya mengintip dari luar. Aku tidak bisa masuk ke ruangan itu. Biosensor plasmonik, sensor pendeteksi molekul biologis berbasis efek plasmonik. Efek plasmonik, sebuah interaksi antara cahaya dan elektron bebas pada permukaan logam. Ketika seberkas cahaya dengan sudut datang dan panjang gelombang tertentu menyinari osilasi elektron terluar pada logam, yang berbatasan langsung dengan medium dielektrik seperti udara atau air, osilasi elektron tersebut akan tereksitasi, mengakibatkan fenomena resonansi plasmon permukaan. Ketika sebuah biomolekul -- seperti DNA, protein, atau virus -- menempel pada permukaan sensor tersebut, indeks bias permukaan sensor itu akan berubah. Perubahan ini mengakibatkan berubahnya sudut bias dan panjang gelombang cahaya yang terbiaskan. Perubahan ini dapat did...

  al-Fajr (الفجر) comes from the root f-j-r, which carries the sense of “splitting” or “bursting forth.” It is used for something breaking open, like water gushing out or light tearing through darkness. So fajr refers to the moment dawn “splits” the night, which is why it names the early morning prayer. aẓ-Ẓuhr (الظهر) comes from the root ẓ-h-r, meaning “to ظهر (appear, become manifest)” or “back.” The connection here is the time when the sun is fully ظاهر, clearly visible and at its peak. It also relates to the middle or “backbone” of the day, which is why ẓuhr refers to the midday prayer. al-ʿAṣr (العصر) comes from the root ʿ-ṣ-r, which originally means “to squeeze” or “press out” (like extracting juice). From this comes a sense of something being “pressed toward its end.” Over time, it developed the meaning of “afternoon” or “declining part of the day,” hence the late afternoon prayer. al-Maghrib (المغرب) comes from the root gh-r-b, meaning “to go away,” “to set,” or “to غرب (be...

I have made quite the discovery. I've been seeing ___ post about naps quite a bit, so when I found myself with some free time earlier today, I decided to try it. Oh. My. Gosh. The rest of the day I was refreshed and on the ball, it was like a whole other world. The air was fresher; the sky was bluer; the chocolate was sweeter. I realized that there has been a huge gap in my life of about fourteen or fifteen years where I took no naps, maybe even longer since I seem to remember messing around during naptime in kindergarten. This has got to change. No longer will I sleep only in a large block at nighttime. If you haven't tried this nap thing lately, you really should. Anyone else recently discover the joy of naps?

Beberapa minggu yang lalu aku dapat kabar kalau operasional usaha kue rumahannya Moona sempat terganggu akibat akun Whatsapp Businessnya terblokir. Dituduh spam, padahal memang lagi banyak pesanan. Hari ini, aku menemukan kasus yang sama di sebuah usaha Wedding Organizer (WO) Aku coba wawancara singkat pemilik akun WO itu. Ia mengaku bahwa akun Whatsapp Businessnya "disandera". Uang tebusannya Rp 600.000 per bulan, bayar ke Meta. Ia pun mengaku telah membayarnya. Sekarang aku jadi pikir-pikir lagi kalau mau menggunakan Whatsapp Business menjadi nomor kontak utama untuk usaha.

Pada sekitar bulan Januari 2025, aku membeli mouse di sebuah tempat fotokopi di pinggir Jalan Dipati Ukur .  Merek mousenya tidak terkenal. Di bagian belakangnya terdapat stiker tanggal, yang dicentang pada "Tahun 24, Bulan 12". Lalu ada tulisan : "Optical Mouse : Tested to comply with FCC Standards. For home or office use. Rating 5V 100mA. Made in China" "The Federal Communications Commission in the United States. An optical mouse contains electronic components that generate small amounts of electromagnetic radiation, mainly from its internal circuits, USB interface, and clock signals. Because of this, it falls under FCC rules for unintentional radiators. The mouse complies with FCC Part 15 regulations, which limit electromagnetic interference (EMI). It has been tested to ensure it does not interfere with other devices, such as radios, Wi-Fi, or TVs." Lalu juga ada logo CE-nya. “CE” stands for Conformité Européenne (“European Conformity”). When a manufact...

 78.33 (“and full-breasted of equal age”. The word kawā‘ib comes from the root k–‘–b, which conveys the idea of something rising or becoming prominent. In classical Arabic usage, it refers to young women whose bodies have reached maturity—often described as having developed physical features associated with youth and vitality. The word atrābā means “of equal age” or “well-matched in age.” The root relates to similarity and correspondence, suggesting harmony, compatibility, and balance among them.) #1 79.37-41 Maka adapun orang yang melampaui batas, dan lebih mengutamakan kehidupan dunia, maka sungguh, nerakalah tempat tinggalnya. Dan adapun orang-orang yang takut kepada kebesaran Tuhannya dan menahan diri dari hawa nafsunya, maka sungguh, surgalah tempat tinggal. 79.45-46 Engkau hanyalah pemberi peringatan bagi siapa yang takut kepadanya.
