MINI RESEARCH: EFFECT OF SPROUT GROWTH ON DIFFERENT WATER SOURCE USERS (RAINWATER, WELL WATER AND MINERAL WATER)

 Did you know that not all water has the same effect on plant growth? Although it looks clear and clean, water from wells, rain, and bottled water can have very different effects on the growth of sprouts. Through a simple experiment with mung bean seeds, we can see firsthand how different water sources affect the speed and quality of plant growth. Let's see the results!

This experiment is very easy and can be done at home. First, put the same amount of cotton into several plastic cups. Then, add the same amount of mung bean seeds to each cup. After that, wet the cotton using three different types of water: well water, rainwater, and mineral water. Observe and record the development of the sprouts every day, such as when they start to grow, how long they are, and how many seeds have successfully germinated.

The experiment began on the first day, and as expected, there were no signs of sprouting in any of the treatments. However, things started to change on the second day. The seeds that were watered with rainwater started to show signs of life—small roots were growing, about 1.5 cm long. The well water also showed some growth, although the sprouts were fewer in number and only 1.2 cm long. Interestingly, the sprouts that were watered with mineral water appeared to grow more evenly, although they were only 1 cm long.

On the third day, the rainwater sprouts continued to grow with healthy white roots that were 3 cm long. The well water was surprising because it produced longer sprouts, up to 5 cm, although some began to appear discolored. The mineral water grew slower, only about 4 cm, and the number of sprouts was smaller.

The fourth day began to show a clear difference. The rainwater sprouts grew the tallest and looked freshest with an average length of 9 cm for 8 sprouts. Well water showed similar growth in length, but only for 6 sprouts. Meanwhile, mineral water was far behind, with a length of 5 cm for only 4 sprouts.

Entering the fifth day, well water began to show its superiority. The sprouts that were watered with this water grew evenly and looked fresh with leaves that were starting to turn green. Their height was also quite impressive, reaching 20 cm for 9 sprouts. Rainwater also remained stable in supporting growth, with sturdy stems and leaves that were starting to increase, although the height was slightly shorter, namely 17 cm for 9 sprouts. Meanwhile, mineral water showed uneven growth. Some sprouts did grow quite long, up to 16 cm, but the stems looked limp and the leaves began to turn yellow—a sign that their growth was not optimal.

On the sixth day, the advantages of well water became clearer. The sprouts grew most fertile with a maximum length of 23 cm and the largest number, namely 10 sprouts that looked healthy and their leaves began to open. Rainwater was still good, with a height of 17 cm on 9 sprouts, and its appearance remained fresh. In contrast, mineral water, although it produced one sprout with a length of 20 cm, but the rest grew weakly, had small leaves, and looked unhealthy.

After six days of experimentation, it turned out that well water was the best for growing mung bean sprouts. The sprouts grew tall, had many leaves, and looked healthy. Rainwater was also quite good, especially at the beginning of growth, but slowed down a bit towards the end. Meanwhile, mineral water was the least suitable—the sprouts grew unevenly, the stems were limp, and the leaves were small or yellowed.

So, if you want to grow sprouts at home, use well water or rainwater for the best results. Mineral water? Better to just drink it!

This experiment shows that choosing the right water source is crucial, even from the early stages of plant growth. For those of you who want to garden at home, consider collecting rainwater as a natural and environmentally friendly alternative to watering plants.🌱💧

GENETIKA: Hukum Mendel I dan II

  HUKUM MENDEL I DAN II Rahasia Warisan Sifat: Memahami Hukum Mendel I dan II Pernah terpikir kenapa ada anak yang mirip sekali dengan ayahnya, tapi punya warna mata persis ibunya? Jawabannya ada di dalam Hereditas, yaitu   proses penurunan sifat fisik dan perilaku dari orang tua ke anak melalui DNA. Tokoh paling berjasa di balik ilmu ini adalah Gregor Mendel . Lewat eksperimen kacang ercisnya, Mendel menyusun dua hukum dasar yang sampai sekarang jadi fondasi ilmu genetika. 1. Hukum Mendel I (Hukum Segregasi) Hukum ini fokus pada Persilangan Monohibrid , yaitu persilangan dengan satu sifat beda (misalnya: hanya melihat tinggi tanaman). Intinya: Saat pembentukan sel kelamin (gamet), pasangan gen dari induk akan berpisah secara bebas. Jadi, jika induk punya pasangan gen "Tinggi-Pendek", maka satu sel gamet akan membawa sifat "Tinggi" dan sel lainnya membawa "Pendek". Poin Penting: Alel Dominan: Sifat yang kuat/menang (ditulis huruf kapital, misal: R ). ...

Keajaiban DNA (Deoxyribonucleic Acid)

 DNA ( Deoxyribonucleic Acid ) Kode Rahasia di Balik Keajaiban Dirimu Banyak yang mengira DNA itu cuma istilah rumit di laboratorium. Padahal, DNA adalah alasan mengapa kamu punya senyum mirip ayahmu, tapi punya sifat keras kepala mirip ibumu. DNA adalah "cetak biru" kehidupan yang lebih canggih dari teknologi mana pun. 4 alasan mengapa DNA itu benar-benar ajaib:  1. Kapasitas penyimpanan yang tak masuk akal Bayangkan seluruh data internet di dunia semua video, foto, dan teks. Jika semua itu diubah menjadi kode DNA, beratnya bahkan tidak sampai satu gram . Tubuhmu punya sistem penyimpanan data paling efisien di alam semesta. Kamu adalah "flashdisk" berjalan dengan kapasitas yang hampir tak terbatas. 2. Jarak yang melampaui tata surya Di dalam satu sel yang sangat kecil, terdapat DNA sepanjang 2 meter. Jika seluruh DNA di tubuhmu ditarik lurus dan disambungkan, panjangnya bisa mencapai ratusan kali jarak bumi ke matahari . Hebatnya, kabel raksasa ini tergulung rapi t...

STRUKTUR DNA

Gambar
DNA: Arsitektur Molekuler dan Rahasia di Balik Kode Kehidupan Struktur DNA ( Deoxyribonucleic Acid ) adalah polimer asam nukleat yang tersusun secara heliks ganda ( double helix ). Struktur ini pertama kali diidentifikasi oleh James Watson dan Francis Crick pada tahun 1953 berdasarkan data difraksi sinar-X dari Rosalind Franklin. Berikut adalah rincian komponen penyusun dan organisasi strukturnya: 1. Nukleotida: Unit Penyusun Dasar DNA terdiri dari rantai panjang unit berulang yang disebut nukleotida . Setiap satu nukleotida tersusun atas tiga komponen: Gugus Fosfat: Menghubungkan satu nukleotida ke nukleotida berikutnya. Gula Deoksiribosa: Gula pentosa (karbon 5) yang kehilangan satu atom oksigen pada karbon nomor 2. Basa Nitrogen: Bagian yang membawa informasi genetik. 2. Basa Nitrogen Terdapat empat jenis basa nitrogen dalam DNA yang dibagi menjadi dua kelompok: Purin (Struktur cincin ganda): Adenin ( A ) dan Guanin ( G ). Pirimidin (Struktur cincin tunggal): Timin ( T ) dan S...
