Abstract

Indonesia, as a tropical country, is rich in essential oil-producing plants, including kaffir lime (Citrus hystrix DC). The leaves of Citrus hystrix are known to contain bioactive compounds such as flavonoids, tannins, and alkaloids, which have potential as natural antibacterial agents. This study aimed to evaluate the antibacterial activity of Citrus hystrix leaf extract against bacteria present in grilled meatballs. An in vitro experimental method using the disc diffusion assay was employed. Fresh Citrus hystrix leaves were obtained through purposive sampling from Medan Krio Village, North Sumatra, extracted using 96% ethanol, and tested against bacteria on Mueller Hinton Agar. Chloramphenicol was used as a positive control, while dimethyl sulfoxide (DMSO) served as a negative control. The results showed inhibition zones of 8.02 mm and 7.09 mm for the leaf extract in two separate trials, whereas the positive control exhibited a 29.91 mm inhibition zone, and no inhibition was observed in the negative control. These findings indicate that Citrus hystrix leaf extract possesses significant antibacterial activity against bacteria in grilled meatballs, although it is less potent than synthetic antibiotics. The extract has potential as a natural antibacterial agent for food preservation.

Abstract

Penelitian ini bertujuan untuk mengevaluasi aktivitas antibakteri ekstrak etanol daun kenanga (Cananga odorata) terhadap bakteri isolat tanah. Penelitian dilakukan secara eksperimental laboratorium (in vitro) dengan menggunakan metode difusi cakram pada media Mueller-Hinton Agar (MHA). Daun kenanga diekstraksi menggunakan etanol 96% melalui metode maserasi dan remaserasi hingga diperoleh ekstrak kental, kemudian diuji pada konsentrasi 100% dan diamati secara kualitatif berdasarkan terbentuknya zona hambat setelah inkubasi selama 24 jam pada suhu 37°C. Hasil penelitian menunjukkan bahwa ekstrak etanol daun kenanga memiliki aktivitas antibakteri dengan zona hambat sebesar 8,5 mm dan 8,16 mm yang tergolong kategori sedang. Aktivitas antibakteri ini disebabkan oleh kandungan metabolit sekunder seperti flavonoid, tanin, saponin, alkaloid, dan minyak atsiri. Meskipun daya hambatnya lebih rendah dibandingkan antibiotik kloramfenikol (22–24 mm), hasil ini menunjukkan bahwa daun kenanga berpotensi sebagai sumber antibakteri alami yang efektif dan ramah lingkungan.

Abstract

Penelitian ini bertujuan untuk mengetahui aktivitas antibakteri ekstrak etanol bunga kecombrang (Etlingera elatior) terhadap bakteri yang diisolasi dari permukaan cangkang telur. Kontaminasi bakteri, khususnya Salmonella sp., sering ditemukan pada cangkang telur dan berpotensi menyebabkan penyakit bawaan pangan (foodborne disease). Bunga kecombrang diketahui mengandung senyawa bioaktif seperti flavonoid, alkaloid, tanin, saponin, dan minyak atsiri yang berpotensi sebagai antibakteri alami. Penelitian ini menggunakan metode eksperimental laboratorik in vitro dengan rancangan post-test only control group design. Uji aktivitas antibakteri dilakukan menggunakan metode difusi cakram dengan tiga perlakuan: ekstrak etanol bunga kecombrang (hasil evaporasi), kontrol positif (kloramfenikol), dan kontrol negatif (DMSO). Hasil pengamatan menunjukkan bahwa ekstrak etanol bunga kecombrang menghasilkan zona hambat 4,18 mm (vertikal) dan 4,49 mm (horizontal) yang tergolong lemah, sedangkan kontrol positif menghasilkan zona hambat 27,44 mm (sangat kuat) dan kontrol negatif tidak menunjukkan hambatan. Hasil ini membuktikan bahwa ekstrak bunga kecombrang memiliki aktivitas antibakteri terhadap bakteri cangkang telur, meskipun efektivitasnya masih lebih rendah dibandingkan antibiotik standar. Senyawa flavonoid, tanin, dan minyak atsiri diduga berperan dalam aktivitas antibakteri melalui mekanisme perusakan membran sel dan penghambatan sintesis protein. Dengan demikian, bunga kecombrang berpotensi dikembangkan sebagai antibakteri alami pengganti antibiotik sintetis.

Abstract

Green beans (Phaseolus radiatus) are one of the commodity of legume plants that are generally grown on dry land, Green beans are included in plants that are tolerant of water shortages, the important thing is that the soil has enough moisture. The problem that is often faced in mung bean cultivation in dry land is the low production achieved by farmers, so it is necessary to conduct research on the resistance of mung beans (Phaseolus radiatus) to drought and the effect of watering frequency on productivity. The purpose was to determine the watering interval to the growth response of mung bean plants (Phaseolus radiatus). This study used an experimental design using a Group Random Design (RAK) consisting of 4 treatments with 3 replicas of each treatment. F0U1, F0U2, F0U3 : Control Treatment (No Watering), F1U1, F1U2, F1U3 : Watering frequency 1 (one) time a day. F2U1,F2U2, F2U3 : Watering frequency 2 (two) times a day. F3U1, F3U2, F3U3 : Watering frequency 3 (three) times a day. The parameters in calculating the growth response are the length of the plant, the number of leaves and the height of the plant. The best watering interval for plant length is watering once every 1 (one) day, where the highest plant length is 56.16 cm in the F1 treatment. The best watering interval for the number of leaves of the plant is watering (once) a day, where the average number of leaves is 13.11 leaves in the F1 treatment. The best watering interval for plant height is watering once every 1 (one) day, where the average height of the highest plant is 51.16 cm in the F1 treatment.
