Abstract

Penelitian ini bertujuan untuk membandingkan perbedaan morfologi pertumbuhan awal kecambah kacang hijau (Vigna radiata L.) saat diletakkan di tempat terang dan di tempat gelap total. Peneliti fokus mengamati empat ciri utama: panjang batang, jumlah daun sejati, vigoritas, dan perubahan warna daun. Metode yang digunakan adalah metode eksperimen dengan menempatkan benih kacang hijau dalam dua kondisi berbeda selama 6 hari: tiga polybag di tempat terang (terkena matahari) dan tiga polybag di tempat gelap total (dimasukkan dalam kardus). Data pertumbuhan, seperti tinggi batang dan jumlah daun, dicatat setiap hari melalui pengamatan langsung dan pengukuran fisik. Hasil penelitian menunjukkan bahwa cahaya adalah faktor yang sangat penting dalam mengatur pertumbuhan kacang hijau. Awalnya, kecambah di tempat gelap mengalami pemanjangan batang yang sangat cepat (etiolasi) sebagai usaha untuk mencari cahaya, tetapi pertumbuhan ini terhambat dan terhenti karena kehabisan cadangan makanan biji dan tidak bisa berfotosintesis. Sebaliknya, kecambah di tempat terang tumbuh lebih lambat di awal, tetapi kemudian menghasilkan batang yang lebih kokoh dan lebih panjang pada akhir pengamatan karena memiliki energi berkelanjutan dari fotosintesis. Selain itu, ada perbedaan warna daun yang mencolok: daun di tempat terang berwarna hijau tua karena produksi klorofil yang optimal, sedangkan daun di tempat gelap tampak kuning pucat dan layu karena gagal membentuk klorofil, meskipun jumlah daun yang muncul sama.

Abstract

Patchouli (Pogostemon cablin Benth.) is a promising export commodity, so techniques such as tissue culture are needed to increase its production. This study aims to determine the effect of BAP (Benzyl Amino Purine) and bean sprout extract (Phaseolus aureus) on the multiplication of patchouli (Pogostemon cablin Benth.) in vitro. This study used a factorial Completely Randomized Design (CRD) with 4 levels of BAP concentration (0 ppm, 0.5 ppm, 1 ppm, 1.5 ppm) and 3 levels of bean sprout extract concentration (0%, 12%, 15%), each treatment was repeated 3 times. Data analysis used ANOVA and further testing with 5% DMRT test. The results showed that the administration of BAP significantly affected the increase in the number of shoots, leaves, and roots. BAP concentration of 0.5 ppm gave the best results on the growth of shoots and leaves, but the treatment without BAP actually produced the best growth in the number of roots. The combination of BAP and bean sprout extract significantly affected the number of shoots and leaves. The combination of 0.5 ppm BAP and 15% bean sprout extract produced the highest number of shoots and leaves, producing 2.92 shoots and 4.28 leaves. The interaction between BAP and bean sprout extract creates natural auxin and synthetic cytokinin hormones derived from BAP, which maintain hormonal balance to support patchouli growth.

Abstract

This study aims to analyze the differences in secondary metabolite content and antioxidant activity in the extract of ground cherry leaves grown in two locations with different altitudes. This study was designed with a descriptive experimental study. The research parameters carried out in the study were secondary metabolite compounds resulting from GC-MS (Gas Chromatography-Mass Spectrometry) analysis and IC50 values ​​were measured using the DPPH (2,2-diphenyl-1-picrylhydrazyl) method. The results showed differences in the content of secondary metabolite compounds and IC50 values ​​of antioxidant activity based on the altitude of the growing place. The extract of lowland ground cherry leaves (Kisaran) produced 13 compounds with a tendency towards carbohydrate/sugar derivatives, such as Melezitose. Meanwhile, the extract of highland leaves (Parongil) produced 11 compounds with a tendency towards alkane derivatives, including Phytol. There was no difference in antioxidant activity influenced by the part of the plant and the altitude of the growing place. The Kisaran ground cherry leaf extract with an IC50 value of 54.46 ppm and the Parongil ground cherry leaf extract with an IC50 value of 98.82 ppm are included in the strong antioxidant activity category. Meanwhile, the Kisaran ground cherry fruit extract with an IC50 value of 120.38 ppm and the Parongil ground cherry fruit extract with an IC50 value of 127.65 are included in the moderate antioxidant activity category.
