One of fermented soybean (Glycine max L. Merr) products is soy milk, called as Thew Fu Sui by the community of Bangka Belitung. Soy milk product has unpleasant aroma or “langu” and need to be processed into alternative product such as yogurt. Soy milk yogurt (soyghurt) was made by utilizing the same bacteria in yogurt-making from animal milk including Streptococcus thermophillus and Lactobacillus bulgaricus. Sugar concentration and incubation time were the factors that influenced the fermentation process and product’s taste. This research was conducted to determine the level of people's preference for soyghurt by organoleptic assessment of color, taste, aroma and texture based on variation of sugar concentration and incubation time of soyghurt. Our study found that various additional sugar concentration and incubation time gave difference result in organoleptic test. Soyghurt with 10%, 12.5%, and 15% of sugar addition became more favorable among the participant. The incubation time of 8 hours, 12 hours, and 16 hours equally produced good fermentation results. Storage in refrigerator for 1 days could maintain its flavor, texture, colour and aroma, but changed after 2 days stored.

Abstract: Acne vulgaris or acne is a skin disease caused by a bacterial infection. This study aimed to evaluate the antibacterial activity of methanol extract of paku resam leaves (Gleichenia linearis Burm.) on three different acne-causing bacteria Propionibacterium acnes ATCC 6919, Staphylococcus epidermidis ATCC 12228, and Staphylococcus aureus ATCC 25923. The research consisted of an antibacterial activity test using the disc diffusion method, a minimum inhibitory concentration (MIC) test, a minimum bactericidal concentration (MBC) test, and an equivalence test of antibacterial activity with clindamycin as a positive control. This study found that the methanol extract of paku resam leaves had a significant effect (p<0.05) on inhibiting the growth of the three bacteria at all concentrations tested, namely 2.5; 5; 10; 15; 20; 30%. The MIC value of the extract was lower for P. acnes ATCC 6919 and S. epidermidis ATCC 12228 by 1.63%, compared to S. aureus ATCC 25923 by 3.25%. The KBM value of methanol extract of paku resam leaves was lower for P. acnes ATCC 6919 and S. epidermidis ATCC 12228 (3.25%) compared to S. aureus ATCC 25923 (6.5%). The equivalence test showed that the antibacterial activity of the methanol extract of paku resam did not as strong as clindamycin inhibitory activity to the acne-causing bacteria. In conclusion, the methanolic extract of paku resam leaves has antibacterial activity toward three acne-causing bacteria based on the antibacterial test, MIC, and KBM tests, but its activity was still lessened than clindamycin.

Local microorganisms (MOL) contain fermented solutions made from various local resources. MOL solution has the potential to be used as liquid organic fertilizer because it contains microorganisms that can increase plant growth. This study aims to determine the characteristics of MOL based on different sources of microorganisms obtained from food ingredients typical of Bangka Belitung, as well as to determine their effectiveness on the growth of Ipomoea reptans (L.) Poir. This experimental study used a two-factorial completely randomized design (CRD), namely the type of MOL (without giving MOL (M0), MOL made from Bangka shrimp paste (M1), MOL made from rusip (M2), and MOL made from kitchen waste (M3)) and MOL dose (0% (D0), 15% (D1), 25% (D2), and 50% (D3)). Each treatment was repeated 2 times with a total of 32 experimental units. The variables observed were the characteristics of MOL after 1 week of incubation and the effect of giving MOL on the growth of Ipomoea reptans (L.) Poir 14 days after planting (HST). Data were statistically analyzed using SPSS software version 25 using the analysis of variance (ANOVA) method and Duncan's multiple range test (DMRT) with a 95% confidence level. The results showed that all MOL treatments were successfully fermented with characteristics of sour aroma, liquid texture, produce CO2, acidic pH, and presence of bacteria and mold. The results of ANOVA showed that the factor of giving the type of MOL and the interaction both factor had a significant effect on all observation parameters. However, the MOL dose factor did not significantly affect all observation parameters. Treatment of interaction the type and dose of MOL M2D1 can increase the response of the number of leaves, plant wet weight, plant dry weight, shoot dry weight, and root dry weight of Ipomoea reptans (L.) Poirs. The teratment of M1D3 increased the height response of Ipomoea reptans (L.) Poirs.

Resam fern (Gleichenia linearis (Burm.) C.B. Clarke) is a terrestrial plant that is easy to grow and has been used for medicinal purposes as by the community empirically. This study aimed to explore the potential of Gleichenia linearis (Burm.) C.B. Clarke) as medicinal plants based on their phytochemical profiles and total phenol content of the extract. Gleichenia linearis (Burm.) C.B. Clarke leaves were extracted with aquadest and methanol as a solvent by maceration method. Phytochemical content was detected qualitatively and the total phenol content was determined using colorimetric method with Folin-Ciocalteu reagent. As the result, qualitative screening for secondary metabolic contents in Gleichenia linearis (Burm.) C.B. Clarke extract found that the aqueous extract contains alkaloids, phenols, flavonoids, tannins, triterpenoids and steroids, but the saponin and steroid were not detected. In the methanol extract, all secondary metabolites were detected except triterpenoids. The total phenol content of methanol extract was higher than that of aqueous extract with levels of 127,08 mg/g GAE and 42,32 mg/g GAE, respectively. Based on these findings, it can be concluded that the Gleichenia linearis (Burm.) C.B. Clarke leaf has the potential to be developed as a medicinal plant.
