Abstract

Kacang hijau (Vigna radiata L.) termasuk ke dalam suku polong-polongan yang mengandung bahan baku berprotein nabati tinggi. Pertumbuhan tanaman kacang hijau dapat dipengaruhi oleh pemberian hormon termasuk hormon etilen yang dapat diperoleh secara alami dari buah. Penelitian ini bertujuan untuk mengetahui pengaruh dari gas etilen alami yang dihasilkan oleh buah tomat (Solanum lycopersicum) terhadap pertumbuhan tanaman kacang hijau (Vigna radiata L.). Gas etilen merupakan hormon tumbuhan berbentuk gas yang berperan dalam proses pematangan dan penuaan, namun pada fase awal pertumbuhan tanaman, gas ini dapat memengaruhi proses perkecambahan dan perkembangan vegetatif. Penelitian dilakukan secara eksperimental selama tujuh hari di Laboratorium Orchidologi Universitas Islam Malang, dengan menggunakan empat perlakuan, yaitu satu kontrol (tanpa tomat) dan tiga perlakuan dengan penambahan tomat. Parameter yang diamati meliputi tinggi batang, bentuk batang, jumlah daun, dan kondisi akar. Hasil penelitian menunjukkan bahwa perlakuan gas etilen dari tomat menghambat pertumbuhan tanaman kacang hijau. Tanaman yang diberi perlakuan menunjukkan batang tinggi lebih pendek, bentuk batang yang tebal dan kerdil, serta jumlah daun lebih sedikit dibandingkan dengan kontrol. Meskipun akar tetap tumbuh lebat, perkembangan tanaman secara keseluruhan terganggu. Kesimpulannya, gas etilen dari tomat memiliki pengaruh negatif terhadap pertumbuhan awal tanaman kacang hijau, khususnya dalam fase perkecambahan dan pertumbuhan batang serta daun

Abstract

The presence of secondary metabolites in plants plays an important role in their biological activities and supports the use of natural ingredients as candidates for phytopharmaceutical development. This study evaluated the phytochemical profile of ethanol extracts of sente leaves (Alocasia macrorrhizos) and guava leaves (Psidium guajava L.), as well as their combined extract. The extracts were obtained using maceration, followed by qualitative phytochemical screening, UV-Vis spectrophotometry, and FTIR analysis. Physicochemical parameters showed that the moisture content of sente and guava leaves was 4.251% and 4.617%, respectively, while the ash content was 0.97% for sente and 0.59% for guava leaves. The extraction yield of guava leaves (3.81%) was higher than that of sente leaves (2.59%). The results showed that A. macrorrhizos contained flavonoids, tannins, and triterpenoids, whereas P. guajava exhibited a more complete profile, including alkaloids, saponins, flavonoids, tannins, and triterpenoids. The combined extract yielded positive results for almost all tested metabolite groups. The UV-Vis spectra showed absorption peaks in the range of 321–369 nm, while the FTIR spectra revealed the presence of –OH, aliphatic C–H, aromatic C=C, and C–O functional groups. Overall, the findings indicate that both extracts and their combination have strong potential as sources of bioactive compounds and may be further developed for phytopharmaceutical applications.

Abstract

Heavy metal pollution in marine waters can enter the food chain and negatively impact aquatic organisms' lives. One organism that is susceptible to exposure is the lamp shell (Lingula unguis), which has the ability to bioaccumulate heavy metals and is often consumed by the public. Considering the health risks posed by heavy metals such as lead (Pb), it is important to test the heavy metal content in clams sold in traditional markets. This study aims to determine the presence and levels of heavy metal Pb in the bodies of lamp shell sold at the Lekok Traditional Market, Pasuruan, East Java. Clam samples were taken purposively based on three sizes: small size ± 5 cm, medium size ± 7 cm and large size ± 9 cm. Pb content testing in lamp shell samples used Atomic Absorption Spectroscopy (AAS) after the digestion process. The results showed that Pb metal content ranged from 5.11 - 9.26 ppm in large clams ranging from ± 9 cm, while no Lead (Pb) content was found in small and medium sized lantern clams. Compared with the maximum quality limit for lead (Pb) contamination for food safety for shellfish according to several national standards, samples of large lamp shell (Lingua unguis) sold at the Lekok traditional market in Pasuruan have exceeded the safe threshold for consumption. Therefore, it is advisable to avoid consuming large lantern clams.

Abstract

Olive plants (Olea europaea) are widely used as traditional medicine and have high economic value, but olive cultivation in Indonesia still faces many challenges. This study aims to evaluate the effect of providing plant growth regulators (ZPT) auxin and cytokinin hormones on the growth of olive shoots and roots using the microcutting method. The study was conducted at the Orchidology Laboratory, Islamic University of Malang with an experimental method of three treatments, namely water control, Biogen, and Bregadium. The parameters observed included the number and quality of shoot and root growth. The results showed that Biogen and Bregadium were able to accelerate the emergence of shoots on the 3rd day, while the control grew on the 10th day. Observations of root growth showed that Bregadium was able to stimulate root formation in more samples even though the quality was still very thin and few. In contrast, Biogen only produced one thin root in one sample. The conclusion of the study states that the combination of Bregadium ZPT hormones has the potential to be more effective in stimulating the growth of olive roots and shoots vegetatively. This study recommends optimizing the concentration and frequency of ZPT application for more optimal growth results.

Abstract

Antibacterial agents from natural biological compounds can originate from phenolic compounds found in plants, including the white pomegranate fruit. However, the use of white pomegranate peel is still relatively unknown to the public, so it is often discarded, even though this part contains phenolic compounds and flavonoids that have potential as natural antibacterial agents. This study aimed to analyse the physicochemical characteristics of white pomegranate peel extract (Punica granatum L.) and evaluate its antibacterial activity against Staphylococcus aureus and Escherichia coli. Peak absorption, wavelength, and functional groups were analysed using UV-Vis and FTIR, while antibacterial activity was tested using the well-diffusion method. The extract was tested at concentrations of 25%, 50%, 75%, and 100% as the treatment factors. The physicochemical test results showed that the moisture content of the simplicia was 3.378%, which met the quality criteria of good simplicia, while the ash content of 19.27% indicated a fairly high mineral content. The UV-Vis spectrum showed absorption at wavelengths of 230–295 nm, indicating the presence of flavonoid compounds, while FTIR results confirmed the presence of alcohol and phenolic functional groups. Antibacterial tests showed that white pomegranate peel extract inhibited the growth of E. coli and S. aureus with the largest inhibition zones at a concentration of 100%, measuring 20 mm and 23 mm, respectively. Based on the inhibition strength category, this extract was strong against E. coli and very strong against S. aureus. Thus, white pomegranate peel extract has the potential to be developed as an effective natural antibacterial agent.

Abstract

Antibiotic resistance in Salmonella typhi has become a major problem in Indonesia, where typhoid fever remains common and the effectiveness of antibiotics is diminishing due to this resistance. Jackfruit leaves (Artocarpus heterophyllus) are a plant source of active compounds such as flavonoids, tannins, and saponins. Meanwhile, chayote (Sechium edule) leaf extract contains active compounds such as saponins and tannins. This study aimed to determine the antibacterial activity of a combination of chayote leaf and fruit extracts against Salmonella typhi, as well as to identify the most optimal concentration. The study employed an experimental design using a completely randomized design (CRD). The treatments consisted of a positive control (chloramphenicol) and a negative control (distilled water), single extracts of jackfruit and chayote leaves at concentrations of 25%, 50%, 75%, and 100%, and combinations of jackfruit and chayote extracts at ratios of 1:1, 2:1, and 1:2, with each treatment repeated three times. Data for the single jackfruit and chayote extracts, as well as the N:LS (1:1) combination, were analyzed using the Kruskal-Wallis, while the N:LS (1:2) and N:LS (2:1) combinations were analyzed using one-way ANOVA. The results of the study showed that all treatments exhibited antibacterial activity ranging from moderate to strong, and the extract combinations demonstrated higher inhibitory activity compared to the single extracts, with the combination of jackfruit leaves and chayote leaves
