Abstract

Tanaman Genjer (Limnocharis flava) adalah salah satu jenis gulma yang memiliki fungsi ganda sebagai bahan pangan nutraseutikan dan agen fitoremediasi. Pemanfaatan Genjer sebagai bahan pangan didasarkan pada kandungan metabolit sekunder yang terdapat didalamnya, seperti flavonoid, fenol, serta antioksidan yang berpotensi untuk dikembangkan sebagai bahan pangan fungsional serta obat tradisional. Selain itu, kemampuan tanaman Genjer sebagai agen fitoremediasi dalam menyerap senyawa pencemar seeperti logam berat, menjadikannya efektif dalam pengelolaan limbah cair. Tujuan review artikel ini dibuat untuk mengeksplorasi keunggulan dan tantangan dalam pengaplikasiannya. Metode penelitian ini yaitu literature review dengan menentukan topik yang dikaji, mengumpulkan artikel – artike, evaluasi, dan interpretasi hasil. Artikel yang digunakan merupakan artikel penelitian dari tahun 2015-2024 dan berasal dari google scholar. Hasil review menunjukkan bahwa tanaman Genjer tidak hanya berperan dalam kesehatan manusia melalui kandungan nutrisinya. Tapi juga mendukung keberlanjutan lingkungan dengan kemampuan sebagai agen fitoremediasi. Dengan pemahaman yang lebih lanjut, tanaman Genjer dapat dioptimalkan sebagai solusi yang inovatif dalam bidang pangan serta lingkungan.

Abstract

Jahe (Zingiber officinale) merupakan tanaman rempah yang banyak tumbuh di Indonesia dan diketahui memiliki potensi sebagai agen antibakteri. Penelitian ini bertujuan untuk membandingkan aktivitas antibakteri minyak atsiri dari tiga varietas jahe yaitu jahe gajah (Z. officinale var. Roscoe), jahe merah (Z. officinale var Rubrum), dan jahe emprit (Z. officinale var Amarum)  terhadap bakteri Bacillus subtilis dan Pseudomonas aeruginosa. Ekstraksi minyak atsiri menggunakan teknik sohkletasi dengan pelarut etanol. Uji aktivitas antibakteri menggunakan metode difusi cakram. Rendemen minyak atsiri tertinggi Z. officinale var Rubrum 23,45 ± 3,32 %, diikuti Z. officinale var Amarum 19,90 ± 2,17 % dan terendah Z. officinale var. Roscoe 15,70 ± 2,42 %. Pada semua konsentrasi uji, kemampuan minyak atsiri jahe dalam menghambat pertumbuhan Baccillus subtilis lebih kecil secara signifikan dibandingkan tetrasiklin dalam tetapi lebih besar pada P. aeruginosa. Hasil uji antibakteri minyak atsiri semua tiga varietas jahe pada konsentrasi 62,6 – 1000 µg/mL terbukti menghambat pertumbuhan kedua bakteru uji dalam kategori kuat yaitu diamter daya hambat > 20 mm. Kekuatan aktivitas antibakteri minyak atsiti terhadap B. Subtilis lebih rendah dari antibiotika standar tetrasiklin, sedangkan terhadap P. aeruginosa lebih kuat. Minyak atsiri ketiga variets berpotensi untuk dijadikan sebagai agen antibakteri terhadap strain gram negatif dan gram positif.  Ginger (Zingiber officinale) is a spice plant that grows widely in Indonesia and is known to have potential as an antibacterial agent. This study aims to compare the antibacterial activity of essential oils from three varieties of ginger, namely elephant ginger (Z. officinale var. Roscoe), red ginger (Z. officinale var Rubrum), and emprit ginger (Z. officinale var Amarum) against Bacillus subtilis and Pseudomonas aeruginosa bacteria. Essential oil extraction was performed using the Soxhlet extraction technique with ethanol as the solvent. Antibacterial activity was tested using the disk diffusion method. The highest essential oil yield was obtained from Z. officinale var. Rubrum at 23.45 ± 3.32%, followed by Z. officinale var. Amarum at 19.90 ± 2.17% and the lowest from Z. officinale var. Roscoe at 15.70 ± 2.42%. At all test concentrations, the ability of ginger essential oil to inhibit the growth of Bacillus subtilis was significantly lower than that of tetracycline, but higher than that of P. aeruginosa. The antibacterial test results of essential oils from all three ginger varieties at concentrations of 62.6–1000 µg/mL proved to inhibit the growth of both test bacteria in the strong category, namely with an inhibition diameter > 20 mm. The strength of the antibacterial activity of essential oils against B. subtilis was lower than the standard antibiotic tetracycline, while against P. aeruginosa it was stronger. The essential oils of the three varieties have the potential to be used as antibacterial agents against gram-negative and gram-positive strains.

Abstract

The improper use of synthetic larvicides results in detrimental environmental impacts. To mitigate these effects, biolarvicides serve as a viable alternative. Plants within the Asteraceae family contain bioactive compounds with potential biolarvicidal properties. This research aimed to explore the potential of Asteraceae species as biolarvicides. This research utilizes Artemisia vulgaris, Cosmos caudatus, Eclipta prostrata, and Tagetes erecta. Extraction was conducted by the maceration method using 96% ethanol. The resulting extracts were analyzed for secondary metabolite content. Data were analyzed using SAS 9.0 software Two-way ANOVA, followed by Tukey’s post-hoc test. Larvicidal bioassays were performed on third-instar Aedes aegypti larvae at concentrations of 1,000-10,000 ppm. The parameters measured included mortality percentage, LC50, and LC90. Morphological changes in dead larvae were observed and compared against a control group. The results indicated that secondary metabolite in the leaf ethanolic extracts were higher than those in the stems and roots. The leaf ethanolic extract of C. caudatus exhibited the highest content of flavonoids (928.3±368.7 mg/g), phenolics (310.2±84.9 mg/g), tannins (187.1± 55.5 mg/g), and saponins (314±95.4 mg/g extract). Conversely, the highest alkaloid content was recorded in the leaf extract of T. erecta (27.8±7.1 mg/g). The highest mortality rate was observed in larvae exposed to A. vulgaris leaf extract, reaching 100% mortality across all concentrations within 24 hours. Consequently, LC50 and LC90 values for A. vulgaris could not be determined. For C. caudatus, the LC50 values were 7204.7 ppm (24 h) and 6839.7 ppm (48 h), while LC90 values were 9077.3 ppm (24 h) 8226.4 ppm (48 h), respectively. E. prostrata yielded an LC50 of 10255.6 ppm and an LC90 of 18048.9 ppm at 24 hours; however, these values were not detectable at 48 hours. T. erecta showed an LC50 of 6569.6 ppm (24 h) and 6397.1 ppm (48 h), with LC50 values of 9682.1 ppm and 9343.3 ppm, respectively. Morphological observations of dead larvae exposed the extracts alterations, including pigmentation, elongation, and shrinkage. While the leaf ethanolic extract of C. caudatus contained the highest concentration of secondary metabolites. The leaf ethanolic extract of A. vulgaris demonstrated the greatest potential as a biolarvicide.
