Abstract

Fermented drinks are drinks that due to the fermentation process produce lactic acid bacteria (LAB) which are good for human digestion. Kombucha is a fermented drink produced from the symbiosis between bacteria and yeast known as SCOBY (Symbiotic Culture Bacteria & Yeast). This study aims to determine the characteristics and antibacterial activity of passion fruit kombucha (Passiflora edulis Sims) against the growth of Escherichia coli and Bacillus subtilis bacteria in vitro. The method used in the antibacterial activity test uses the disc diffusion method with concentrations of 20%, 30%, 40% and 50%. This study shows the antibacterial activity of passion fruit kombucha (Passiflora edulis Sims) using concentrations of 20%, 30%, 40% and 50% with the results of the inhibition zone diameter of Escherichia coli bacteria of 10.4 mm, 12.3 mm, 14.2 mm, and 16.3 mm. While Bacillus subtilis bacteria are 14.5 mm, 16.6 mm, 17.8 mm and 18.3 mm. The characteristics of passion fruit kombucha juice have a pH value that is increasingly acidic when the concentration given is higher. Concentrations of 20%, 30%, 40% and 50% have a distinctive kombucha aroma and are golden yellow in color. Concentrations of 40% and 50% have a sour taste. Based on an average concentration of 50% on Escherichia coli bacteria and a concentration of 30% on Bacillus subtilis bacteria, it has effective inhibitory power in inhibiting bacteria.

Abstract

Daun kemangi (Ocimum basilicum L.) telah lama dikenal sebagai tanaman herbal dengan aktivitas antibakteri dan antiinflamasi, sedangkan cangkang telur mengandung mineral dan protein yang dapat memperbaiki kesehatan kulit. Kombinasi kedua bahan alami ini berpotensi dikembangkan menjadi produk perawatan kulit, khususnya masker anti jerawat. Penelitian ini bertujuan untuk mengembangkan masker gel peel-off anti jerawat berbahan kombinasi ekstrak daun kemangi dan cangkang telur. Daun kemangi dipilih karena kandungan flavonoid, alkaloid, dan tanin yang bersifat antibakteri, sedangkan cangkang telur kaya akan kalsium dan protein yang bermanfaat untuk kesehatan kulit. Metode penelitian meliputi ekstraksi maserasi, uji fitokimia, dan uji aktivitas antibakteri terhadap Propionibacterium acnes menggunakan metode difusi cakram. Hasil uji fitokimia menunjukkan adanya senyawa aktif seperti flavonoid, alkaloid, dan tanin. Uji antibakteri menunjukkan bahwa formula dengan konsentrasi 3% ekstrak daun kemangi dan cangkang telur menghasilkan zona hambat sebesar 9,36 mm, sedangkan kontrol positif (klindamisin) menghasilkan 14,1 mm. Evaluasi karakteristik fisik masker gel (pH, daya lekat, daya sebar, waktu kering) memenuhi standar SNI. Kesimpulannya, kombinasi ekstrak daun kemangi dan cangkang telur berpotensi sebagai bahan aktif dalam masker gel peel-off anti jerawat, meskipun efektivitasnya masih di bawah antibiotik standar. Kata kunci: Ekstrak daun kemangi, cangkang telur, masker gel peel off, Propionibacterium acnes

Abstract

Vitamin A, yang ditemukan dalam konsentrasi sangat tinggi pada pakcoy, membantu menjaga kesehatan kornea. Karena penggemarnya yang setia dan risiko kehilangannya yang kecil, vitamin A mungkin sangat bermanfaat bagi pakcoy. Rendahnya kesuburan tanah yang dikarenakan pupuk anorganik yang berlebihan merupakan faktor yang membuat rendahnya produksi pakcoy di Indonesia. Oleh karena itu, penggunaan biosaka dan pupuk organik diharapkan bisa memperbaiki struktur tanah serta penyerapan hara oleh tanaman. Tujuan dari penelitian ini yaitu untuk mengetahui pengaruh perlakuan biosaca dan pupuk organik terhadap pertumbuhan serta hasil tanaman pakcoy (Brassica rapa L.) serta kombinasi biosaca dan pupuk organik. Penelitian ini dilaksanakan pada bulan Juni dan Agustus 2024 di Jalan Sunda, Desa Bakaran Batu No. 007, Dusun III, Kecamatan Lubuk Pakam, Kabupaten Deli Serdang. Penelitian ini menggunakan rancangan acak kelompok (RAK) faktorial dengan dua komponen dan tiga kali ulangan. Dengan tiga taraf pemberian 1 ml/liter air (B1), 2 ml/liter air (B2), dan 3 ml/liter air (B3), biosaca sebagai faktor pertama. Pupuk organik sebanyak 25 ton/ha (P1), 35 ton/ha (P2), dan 45 ton/ha (P3) sebagai komponen kedua. Analisis varians dan Uji Jarak Berganda Duncan (DMRT) α = 5% digunakan untuk menguji data yang terkumpul. Berdasarkan hasil penelitian, jumlah daun tanaman pakcoy (Brassica rapa L.) meningkat secara signifikan ketika biosaca diberikan; perlakuan optimal adalah 2 mililiter per liter air (B2). Jumlah daun pada tanaman pakcoy (Brassica rapa L.) meningkat secara signifikan ketika pupuk organik diberikan; perlakuan optimal adalah 45 ton/ha (P3). Laju pertumbuhan relatif tanaman pakcoy (Brassica rapa L.) dipengaruhi secara signifikan oleh pemberian biosaka dan pupuk organik; perlakuan optimal adalah 2 mililiter per liter air dan 25 ton per hektar (B2P1).

Abstract

Pakcoy comes from the Brassicaceae family, known for being rich in nutrients, including vitamins A, C, K, as well as fibres and minerals. Onion skin contains bioactive compounds that have the potential to be organic fertilizers, while sugarcane bagasse is agricultural waste that can be used as an alternative planting medium. This study aims to determine the effect of soaking shallot skin using sugarcane bagasse planting media for the growth of Pakcoy (Brassica rapa L.). This study was conducted in Tuntungan II village using the factorial Randomized Block Design (RAK) method consisting of two factors and 3 replications with 3 treatment levels. The parameters observed included relative growth rate, net assimilation rate, number of leaves, total leaf area, wet weight and dry weight of pakcoy plants. The results showed that the combination of onion skin soaking gave a significant effect on all red parameters (B2: 250 ml/500 ml water) and bagasse gave a significant effect on the net assimilation rate of 2-3 MST and 4-5 MST in the treatment of 500 gr/polybag bagasse but on other parameters the control treatment was better. Thus, the provision of onion skin soaking as organic fertilizer with bagasse planting media on the growth of pakcoy plants can be applied in agriculture, because this treatment has a significant effect on all treatments.

Abstract

Aloe vera is a tropical plant with significant potential to develop into a promising agricultural sector in Indonesia. To achieve high-quality Aloe vera harvests, it is important to pay attention to several growth conditions, especially plant care such as fertilization. This study aims to determine the effect of Photosynthetic Bacteria (PSB) fertilizer application and the effective dosage of PSB fertilizer for the growth of Aloe vera using vertical farming techniques. This research used a Non-Factorial Randomized Block Design (RBD), with treatment factors including: no application of PSB fertilizer (P0), PSB 5 ml/l (P1), PSB 15 ml/l (P2), and PSB 30 ml/l (P3). The research involved several stages of observation, including plant height, number of leaves, leaf width, leaf thickness, and root volume. The observed data were analyzed using ANOVA with the help of SPSS 26. If the ANOVA test showed a significant effect, further analysis was carried out using Duncan's Multiple Range Test (DMRT). The results showed that the application of PSB fertilizer had an effect on plant height (22.8 cm), leaf width (2.76 cm), number of leaves (7 leaves), leaf thickness (8.91 cm), and root volume (4 cm³). The best average treatment result for Aloe vera growth was obtained at a dosage of 15 ml/l (P2), indicating that Photosynthetic Bacteria (PSB) fertilizer at a dosage of 15 ml/l (P2) was sufficient to supply the necessary nutrients for the growth of Aloe vera.
