Soil fertility is the relationship between the physical, chemical and biological properties needed by plants to grow and develop. The land used as a medium for growing mustard greens is taken from Bahway Village. The soil is treated with organic and inorganic fertilizers to test its fertility. The data analysis used was one way ANOVA and the least significant difference test and a randomized block design with three treatments and two replications. The treatments were: P1=100% organic fertilizer, P2=100% inorganic fertilizer, P3=50% organic fertilizer + 50% inorganic fertilizer and control. Based on the research results, it is known that the type of soil texture in P1 and P2 has a clay-sand texture, while P3 and C have a sandy loam texture. In terms of chemical properties, the pH at P1, P2, P3 and C are 5.53, 5.79, 5.50 and 6.20. For available P values, P1 = 188.31 ppm, P2 = 7.44 ppm, P3 = 113.62 ppm, and C = 2.48. Availability of Cation Exchange Capacity P1 = 22.56me/100g, P2 = 21.80me/100g, P3 = 23.19me/100g, and C = 23.75me/100g. From these results, what showed that the growth of mustard plants increased was the P3 treatment.
This study aimed to determine the effect of giving liquid tofu fertilizer to the growth and yield of red spinach plants (Alternanteraamoenavoss) with floating raft hydroponic techniques. Research on red spinach growth parameters was carried out at Horti Park Lampung. The method used in this study was Complete Random Design (CRD) consisting of 4 concentration P0 (0% AB Mix), P1 (30%), P2 (45%) and P3 (60%) and 3 replications. The study was conducted for 4 weeks. Measurements and observations are carried out 4 times, i.e. every 1 week. The parameters measured were stem height, number of leaves, leaf width, root length. Then, the data analysis was performed using One Way ANOVA on SPSS 17, and register later with the LDS test at the level of 5% significance. The results showed that tofu wastewater available at P3 maintenance (60%) was significantly different from other treatments, and at the same time discussed liquid waste which was known at the time of preparation of P1 (30%) because, it did not depend on nutrients contained in inside, so it causes less growth, compared to the implementation of P0 (0%), P2 (45%) and P3 (60%).
Traditionally, Senna Alata (L.) Roxb (Ketepeng Cina) has been used as an alternative medicine for typhus, diabetes, malaria, herpes, eczema, asthma, stomach ulcers, syphilis, influenza, bronchitis, intestinal worms, fungal skin diseases such as tinea versicolor, ringworm and scabies. The study's objective was to determine the active compounds, antioxidant potency and antifungal activity of Senna Alata (L.) Roxb leaves extract. Samples were extracted using the maceration method with 70% ethanol, ethyl acetate and N-hexane as solvents. Phytochemical analysis used the Harbone method, antioxidant testing using 2,2-diphenyl-1-picrylhydrazyl (DPPH) method and antifungal testing using the agar diffusion method. Phytochemical results proved that all Senna Alata (L.) Roxb leaves extract contained alkaloids, saponins, tannins, flavonoids, triterpenoids, steroids, glycosides. While the antioxidant test stated that ethanol and ethyl acetate solvents had solid antioxidant potential with the Inhibition Concentration (IC50) values obtained were 66.01 ppm and 78.23 ppm respectively. While the solvent N-hexane has a moderate antioxidant potential, the IC50 value obtained is 138.80 ppm. The diameter inhibition zones of ethanol, ethyl acetate, and N-hexane extracts against the Candida albicans were 8.66 mm, 10.22 mm and 8.84 mm, respectively. Cryptococcus neoformans was only inhibited by ethyl acetate and N-hexane Senna Alata (L.) Roxb leaves extracts with diameter inhibition zones of 4.84 mm and 4.44 mm, respectively. Key words: Antifungal, Antioxidant, Candida albicans, Cryptococcus neoformans, Phytochemical , Senna alata (L.) Roxb.
Serum total cholesterol levels above 200mg/ () have repeatedly been correlated with cardiovascular and other degenerative diseases. Many risk factors can lead to , one of which is the dietary pattern. A dietary pattern is one simple way to start, which can be modified to avoid . This study describes the correlation between dietary pattern with serum total cholesterol levels within HKBP church congregation in September 2018 using a cross-sectional study, and the sample was obtained from accidental sampling. Therefore, there is no requirement for both inclusion and exclusion criteria. In total, 38 respondents contributed to this research. Data retrieval was done using questionnaires for the dietary pattern and rapid test for the serum total cholesterol levels. The data was used to analyze by the Pearson Chi-Square test. Based on the study result, there was a significant relationship between carbohydrate consumption frequency with the respondents' serum total cholesterol levels (p = 0,031). In contrast, the significant relationship between protein consumption frequency (p = 0,631), fat consumption frequency (p = 0150), fiber consumption frequency (p = 0,631) and fast-food consumption frequency (p = 0,150) with serum total cholesterol levels of the respondents were not found.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
