Abstract

The national demand for carbohydrates in flour continues to increase significantly due to the emergence of contemporary food products that use flour as the primary ingredient. One of the products used in producing food is sourdough, which is fermented flour. Lactic acid bacteria (LAB) have a role in food fermentation by producing lactic acid. Amylolytic LAB can produce amylase enzyme, a biocatalyst in the starch hydrolysis process. One of the products made from the fermentation of wheat flour is sourdough. This study aims to determine the character of amylolytic LAB in wheat and wheat flour fermentation. The research methods include rejuvenation of LAB, selection of isolates, fermentation of starchy materials, and characterization of fermented liquid. The selection of bacteria was based on cell viability and pH, which showed that isolated Pediococcus pentasaceus E1222 could be used as a starter for starchy fermentation. The highest total acid and cell viability were produced in 24-hour wheat and wheat flour fermentation. Fermented wheat flour and flour had the most favorable aroma and texture, and fermented flour had the most favorable taste. Isolate Pediococcus pentasaceus E1222 is an isolate that can be used in making sourdough.

Abstract

Ginger (Zingiber officinale) is one of the spice plants used for cooking or traditional medicine in Indonesia. Ginger variations are highly diverse in the Garut region, hence there is a need for the characterization of ginger plants to identify the germplasm present in the Garut area. This research was conducted at several points in the Garut region by observing the morphological characteristics of ginger based on Union for the Protection of New Varieties of Plants. The morphological characteristics observed include overall plant morphology, including stem, leaves, and rhizomes. After the data were collected based on predetermined criteria according to descriptors, the data were processed using NTSYS 2.1 to determine the relatedness of the ginger varieties found. Based on the analysis of the dendrogram results, it is shown that among the red ginger varieties (A1 and A5), there is a coefficient value of 0.65, indicating a high similarity in properties. Elephant ginger (A3, A2) and emprit ginger (A6) have a coefficient value of 0.45, indicating a close relatedness between elephant ginger and red ginger, while elephant ginger (A4 and A7) has a coefficient value of 0.50, indicating close relatedness.

Abstract

The existence and population conditions of the rare, sensitive or tolerant lichens of Lobaria, Coccocarpia, Coenogonium, Dictyonema, Pseudocyphellaria, Sticta, Usnea, Leptogium, and Parmotrema tinctorum are not yet known in West Belitung Regency, so this research needs to be carried out. The method used in this research was exploratory descriptive with survey techniques and purposive sampling. The number of target lichen thallus was calculated from the entire area of the tree trunk with a height of 0-1.5 m. The lichens found in the Gunung Tajam area were Coccocarpia sp. with the highest number of thallus and the highest frequency of thallus (0.8%), followed by Coenogonium sp., Leptogium sp., and Usnea sp. with the same frequency of thallus (0.4%) while in the Batu Mentas area lichens were not found as the research target, but was dominated by fruticose lichen. Parmotrema tinctorum, the tolerant lichen, was not found at either location. The presence of sensitive lichens and the absence of tolerant lichens does not indicate that the locations have good air quality. It is recommended that the lichen population, especially P. tinctorum, be studied further so that air quality can be easily confirmed through the diversity and population of the lichens.

Abstract

Swietenia macrophylla or big-leaf mahogany is an exotic species from Central and South America. This tree has various benefits, so it’s used as an industrial plantation forest and afforestation in Indonesia. However, seed storage of mahogany is a major problem in cultivation, because it can reduce seed viability. The storability of seeds is influenced by seed and environmental conditions. Therefore, this study aimed to examine the effect of temperature and storage time on the viability of S. macrophylla seeds and to calculate the Seedling Quality Index (SQI). The experiment was carried out using a factorial Randomized Block Design (RBD) with 2 factors. The first factor was consisted of four levels of temperature treatment, namely room temperature (24), 4, 0, and -20°C. The second factor was the storage period treatment which consisted of 4 levels, namely 1 up to 4 weeks, with 1-week intervals. The results showed that the interaction between temperature and storage time affected mahogany leaves, primary and secondary roots, root/shoot ratio, and total wet weight of S. macrophylla seedlings. Mahogany seeds that were stored at room temperature for 1 week resulted in the highest seed viability, with SQI of 0.03-0.04.

Abstract

Various natural interactions exist between fungi and plants, including mutualism and pathogenesis. This study evaluated the interaction of fungi Acremonium sp. to plants and pathogenic fungi. Acremonium sp. was isolated from the root tissue of an oil palm plant using surface sterilization methods before isolation. The potential pathogenicity interaction of Acremonium sp. was assayed towards Chinese white cabbage (Brassica rapa L. var. pekinensis) in vitro. Based on the PDA medium assay, isolated Acremonium sp. exhibited pathogenic traits against Chinese white cabbage within 14 days post-inoculation. Interestingly, Acremonium sp. showed antifungal activity against Fusarium oxysporum IPBCC.19.1468, with an average inhibition rate of 69.11%. Our data suggest the pathogenicity interaction of Acremonium sp. toward cabbage plant and fungi F. oxysporum IPBCC.19.1468.

Abstract

IPB CP1 potato is a raw material for potato chips. The advantage of IPB CP1 potatoes is their high yield. Challenges in potato production are limited areas with optimal altitude and condition as well as low quality and quantity of seeds. Utilizing a mid-altitude area for potato cultivation is one of the solutions to increase potato seed production. This study aimed to compare the growth and production of IPB CP1 G0 seed tuber in a greenhouse and screenhouse in mid-altitude with different numbers of shoot cuttings per polybag. This research was conducted with two factors. The first factor is the use of growth plant houses, i.e. greenhouse and screenhouse. The second factor is the number of shoot cuttings per polybag, i.e. 2 and 3 shoot cuttings per polybag. Growth parameters observed included plant height, number of nodes and leaves, and fresh and dry weight of shoots. The production parameters observed included the number as well as fresh and dry weight of tubers. The growth and production of IPB CP1 potatoes grown in the greenhouse were better than those grown in the screenhouse. The number of cuttings per polybag did not affect the growth and production of IPB CP1 potato.

Abstract

Most of the microbes inhabiting the oral cavities are harmless but can cause disturbance and discomfort if the microbial population increases significantly. One of the oral disorders that is often experienced by children, is dental caries. Dental caries is causedby various factors, including eating and brushing habits. The people of Central Kalimantan who live in the watershed use peat water in their daily activities, including for gargling and brushing their teeth. The acidic characteristics of peat water and the high content of organic substances trigger the development of microbes that cause dental caries.This study used dental caries swab samples of patients who rinsed their mouths with peat water. Bacteria were identified molecularly with 16SrRNA markers with primers 63F and 1387R. The similarity of nucleotide sequences was analyzed with BLAST on GeneBank. A phylogenetic tree was built with Maximum Likelihood. Both isolates have a fairly high level of similarity to Klebsiella pneumoniae, namely 91% and 93%. Both isolates are in the same clade, Klebsiella spp., and are close to various commonly found bacteria in the oral cavity, such as Streptococcus mutans and Lactobacillus salivarius.

Abstract

Honey bee workers perform colony defense behavior to maintain colony integrity against predators. The aim of this research was to explore the response of A. cerana defensive behavior by using Isopentyl Acetate (IPA) as the stimulus which is the main volatile compound in the venom. Five concentrations of IPA volume i.e. 10, 20, 30, 40, and 50 µL IPA were used as the stimulus and each volume was pipetted to a cotton ball. The cotton ball was placed 10 cm in front of the hive entrance in oscillatory motion for five minutes. Natural defensive behavior of A. cerana (balling behavior), balling temperature and A. cerana predator were observed. Observation of defensive behavior was conducted by using colonies A. cerana obtained from Parung Panjang, Bogor and Nyalidung, Sukabumi; and using colonies A. cerana obtained from Sumedang and Banjarsari, Lebak. Based on the research, five A. cerana defensive behavior responses were observed, i.e.: guarding in front of bee hive entrance, recruitment at the hive entrance, fly toward the cotton ball, balling around the hive entrance, and balling on cotton ball. A. cerana showed defensive behavior due to IPA stimulus, however, there was no significant difference (P>0.05) with the variety IPA stimulus volume. We found the temperature of 44°C inside the natural balling of A. cerana defense behavior, as the colony defense mechanism in response to the natural predator Vespa sp. wasp.

Abstract

Candidiasis is a fungal infection due to a decrease in the immune system caused by Candida spp. In general, candidiasis is treated with antifungal drugs, but uncontrolled use can result in the emergence of drug resistance and toxicity. Endophytic bacteria have the potential to be biological control agents against various fungal infections including candidiasis. This study aims to determine the antagonistic activity of endophytic bacteria isolated from Dayak onions and the antifungal activity of its cell-free supernatant (CFS) against Candida albicans. Thirteen isolate strains of endophytic bacteria were used in this study. Antagonistic activity was tested using the agar plug diffusion method. Endophytic bacteria that showed antagonistic activity against C. albicans were cultivated in Nutrient Broth media to produce CFS. The antifungal activity of CFS was tested using the Kirby–Bauer disk diffusion method. The results indicated that six isolates of endophytic bacteria from dayak onions have antagonistic activity against C. albicans. CFS from strain CED4 has a strong antifungal activity against C. albicans with a clear zone diameter of 18.5 mm. Further studies are needed to determine the antifungal compounds produced by CED4 isolates for the development of anticandidal.
