Abstract

The food crisis is a condition when acute food hazards and net malnutrition increase sharply. One reason is due to a slowdown in food production. In 1627, a new farming method was known, called hydroponics, namely the method of growing with the help of water. After further investigation, it was found that the cultivation method with water will eventually produce plants that are as good as plants grown using soil media. Therefore, this research will explore the benefits of using hydroponic media in leek cultivation. In this study, there were two containers, the first container was not subject to the application of pesticides, while the second container was watered with onion peel vegetable pesticides twice a week. The results of the leek planting experiment in the hydroponic system and media showed that the maximum height achieved by the leek plants tested was as high as 22.8 cm, and only 3 out of 17 total plants died.

Abstract

The accumulation of plastic waste is one of the main problems being faced by various countries in the world. The nature of plastic which is not easily degraded naturally will consequently be buried in the soil so that it will gradually change the soil components. Plastic belongs to a group of multifunctional complex polymers which have become conventional products in all sectors of life. The use of plastic on a large scale has an effect on increasing the amount of waste, such as the types of High Density Polyethylene (HDPE) and Low Density Polyethylene (LDPE) plastics. This study aims to obtain indigenous bacterial isolated from various soil samples in the landfill area and mangrove forests in Surabaya on the degree of degradation of HDPE and LDPE plastic polymers. Two places namely the final disposal site (TPA) and the Keputih bamboo forest in Surabaya. Sampling at landfill sites and mangrove forests. Then isolate the bacteria from soil samples and plastic waste obtained. Next, purification and screening of HDPE and LDPE polymer plastic degrading bacteria. The results of the isolation succeeded in obtaining 19 types of isolates that can grow on media containing plastic, with the majority having the characteristics of bacilli, Gram negative, catalase positive, capable/incapable of fermenting glucose and lactose and having cell sizes between 1-5 µm. Screening test results obtained that isolate 2 (K1D2U2 KPH) isolated from the Keputih Final Disposal Site (TPA) was identified as a Bacillus sp., with HDPE degradation ability of 27.13% and Isolate 17 (K2D3U1 MWJ) which was isolated from the Wonorejo mangrove forest was identified as a Pseudomonas sp. with LDPE degradation ability of 21.64%. Keywords: Plastics, HDPE, LDPE, Pseudomonas sp. and Bacillus sp.

Abstract

Aeromonas hydrophila bacteria can cause Motile Aeromonas Septicemia (MAS), a disease that impacts freshwater fish. The turmeric rhizome contains numerous bioactive compounds that act as antibacterials and might be utilized to inhibit A. hydrophila. This research aimed to identify the phytochemicals in turmeric (Curcuma domestica) infusion, evaluate its antibacterial activity against A. hydrophila, and define the toxicity effect of turmeric rhizome infusion. The agar dilution method was used to measure antibacterial activity, whereas the Brine Shrimp Lethality Test (BSLT) was used to assess toxicity. The research confirmed the presence of phytochemicals such as tannins, alkaloids, flavonoids, phenols, and saponins in a turmeric rhizome infusion. According to the findings, the infusion from turmeric rhizome effectively inhibited the growth of A. hydrophila at concentrations between 750-1000 ppm. In toxicity tests, the LC50 value of the turmeric rhizome infusion against shrimp larvae was 381.18 ppm. Hence, the turmeric rhizome infusion has the potential to be further developed for the prevention and treatment of fish infected with A. hydrophila in freshwater fish farming.

Abstract

Streptococcus mutans is the prior bacteria causing dental caries. Suruhan (Peperomia pellucida) may prevent dental caries due to its antibacterial bioactive content. This study aims to identify the bioactive profile of Suruhan ethanol extract and its antibacterial activity against Streptococcus mutans. Bioactive compounds were analyzed using Gas Chromatography-Mass Spectrometry (GC-MS). Antibacterial activity was tested through an inhibition test using the well-diffusion method, the Minimum Inhibitory Concentration (MIC) test, and the Minimum Bactericidal Concentration (MBC) test. The most detected compounds in Suruhan ethanol extract were n-eicosane, n-hexadecane, and glycerol. There are also antibacterial bioactives such as phenols, flavonoids, alkaloids, and terpenoids. Inhibition test of 500 mg/mL extract showed a clear zone of 8.25 mm diameter. The MIC and MBC values were 50 mg/mL and 100 mg/mL, respectively. Based on the results, Suruhan ethanol extract shows potential as an antibacterial, although its inhibitory effectiveness could be better.
