Abstract

Kajian literatur ini bertujuan untuk (1) mendeskripsikan kadar mioglobin pada beberapa spesies ikan air tawar, (2) menjelaskan hubungan antara kadar mioglobin otot dengan kemampuan menyelam atau bertahan pada kondisi hipoksia, serta (3) mengidentifikasi spesies yang memiliki kadar mioglobin tinggi dan ketahanan menyelam paling lama. Hasil analisis literatur menunjukkan adanya perbedaan karakter struktural mioglobin antarspesies, yang memengaruhi kapasitas penyimpanan oksigen. Ikan gabus dan lele memiliki kadar mioglobin tinggi serta struktur mioglobin dengan afinitas oksigen kuat, memungkinkan keduanya menyimpan oksigen lebih banyak di jaringan otot dan bertahan lama saat hipoksia. Sebaliknya, ikan nila, gurame, dan ikan mas memiliki kadar mioglobin rendah–sedang sehingga daya tahan menyelam lebih rendah. Temuan ini memperkuat konsep bahwa mioglobin berperan penting dalam adaptasi fisiologis ikan air tawar terhadap kondisi oksigen rendah, dipengaruhi habitat, kebutuhan metabolik, dan struktur respirasi.

Abstract

Kacang hijau (Vigna radiata L.) merupakan tanaman legum penting sebagai sumber karbohidrat dan protein. Peningkatan pertumbuhan tanaman dapat dilakukan melalui intensifikasi budidaya, salah satunya dengan penggunaan Monosodium Glutamat (MSG) sebagai biostimulan. Penelitian ini bertujuan untuk mengetahui pengaruh penyiraman air dan larutan MSG terhadap pertumbuhan awal kacang hijau. Metode yang digunakan adalah percobaan dengan dua perlakuan, yaitu penyiraman air dan MSG, menggunakan media tanah dalam polybag. Parameter yang diamati meliputi tinggi tanaman, jumlah daun, dan panjang daun selama tujuh hari. Hasil penelitian menunjukkan bahwa penyiraman air menghasilkan pertumbuhan yang lebih stabil, sedangkan pemberian MSG mampu mempercepat pertumbuhan awal tetapi bersifat fluktuatif pada hari berikutnya. Oleh karena itu, penggunaan MSG perlu dikontrol agar tidak menghambat pertumbuhan tanaman. Rendahnya produktivitas ini disebabkan oleh penggunaan benih non-unggul, pemupukan yang kurang tepat, serta kondisi tanah yang kurang subur. Oleh karena itu, diperlukan upaya untuk meningkatkan produksi kacang hijau melalui penerapan teknologi budidaya yang lebih efisien dan ramah lingkungan. Namun, kajian mengenai pengaruh MSG terhadap pertumbuhan awal kacang hijau dalam skala polybag dan pengamatan harian masih terbatas.

Abstract

Pertumbuhan awal tanaman, khususnya fase perkecambahan, sangat dipengaruhi oleh media tanam. Penelitian ini bertujuan untuk menganalisis pengaruh jenis tanah (humus, liat, dan pasir) terhadap percepatan perkecambahan dan pertumbuhan vegetatif awal kacang hijau (Vigna radiata L.). Desain yang digunakan adalah eksperimental sederhana dengan satu faktor perlakuan, dan pengamatan dilakukan selama tujuh hari. Hasil penelitian menunjukkan bahwa tanah humus memberikan waktu muncul radikula tercepat (24 jam) dan plumula tercepat (48 jam). Keunggulan ini karena humus memiliki aerasi, bahan organik, dan kapasitas menahan air yang seimbang. Sebaliknya, tanah pasir menunjukkan waktu muncul paling lambat (radikula 48 jam; plumula 72 jam) karena retensi air dan hara yang rendah. Selain itu, tanah humus juga menghasilkan pertumbuhan awal terbaik, dengan tinggi rata-rata 11 cm dan 3 helai daun sejati pada hari ke-7, jauh melampaui tanah liat (7,5 cm) dan pasir (4,2 cm). Kesimpulan menunjukkan bahwa jenis tanah memengaruhi secara signifikan laju perkecambahan dan pertumbuhan awal; tanah humus adalah media tanam yang paling optimal untuk budidaya kacang hijau.
