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

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

This study aims to investigate the effectiveness of the Partial Rootzone Drying (PRD) irrigation method, the application of goat manure as organic fertilizer, and the interaction of both treatments on the growth and yield of tomato plants (Lycopersicum esculentum Mill) in North Sumatra. The research responds to the urgent need for sustainable agricultural practices that conserve water and enhance soil fertility, especially in tropical regions facing irregular rainfall and declining soil quality. A field experiment was conducted using a factorial randomized block design to test various levels of goat manure combined with the PRD technique. Observations focused on vegetative growth parameters (plant height, number of leaves, dry weight, chlorophyll content, Relative Growth Rate), nutrient uptake (N, P, and K), and production indicators (fruit number and sugar content). Data were analyzed statistically to determine the significance and interaction effects of treatments. The results show that goat manure significantly improves vegetative growth and fruit production, with higher doses correlating positively to increases in biomass and nutrient uptake. The PRD method led to a 25% reduction in water use without compromising plant productivity. Importantly, the combination of PRD and organic manure application produced synergistic effects, enhancing both growth and yield while optimizing water and nutrient efficiency. This study introduces a novel integrated approach to tomato cultivation that combines precision irrigation (PRD) and organic soil enrichment, offering a replicable model for sustainable, water-efficient horticulture in resource-constrained agricultural regions.
