Abstract

Pteridophytes are able to live in a variety of habitats resulting in high species diversity. However, in monoculture vegetation such as tea plantations, species diversity can be reduced. This study aimed to compare the composition of the pteridophytes on the edge of the main road and the area in the tea garden at the Nirmala Tea Plantation, Kabandungan District, Sukabumi, West Java. Samples were collected using the exploratory method, then identified and observed for their morphological characteristics, and then the data were analyzed descriptively. The diversity of pteridophytes in the tea garden area (18 species) was lower than the main roadside tea plantation (25 species). Some species in the tea plantations were only found in the tea garden area (7 species) or on the side of the main roadside (14), and there were also species found in both locations (11 species). Pteridophytes in the study area is dominated by terrestrial ferns and the Polypodiaceae family. Soil moisture and wind speed are more influential factors on the diversity of pteridophytes than other abiotic factors measured. This result is new information on the diversity of fern in the Tea Plantation.

Abstract

Rice is an important food crop with a crucial role in global food security. Study on correlation between morphoagronomic traits and yield is an important step in the development of superior rice varieties. Research data were collected from 20 rice varieties grown in the experimental field. A total of 10 morphoagronomic trait variables were measured, including plant height, number of productive tillers, flowering age, dry weight of biomass, hollow grain, 1,000-grain weight, grain weight, panicle number, panicle length, and harvest index. Data were analyzed using variance, correlation, and principal component analyses. The results of PCA showed that 3 principal components (PC) explained 80.88% of the data variation. PC1 was associated with plant height, flowering age, biomass dry weight, empty grain, panicle length, grain weight per clump. PC2 was associated with 1,000-grain weight and harvest index, while PC3 was associated with number of productive tillers and number of panicles. Correlation analysis showed that 1,000-grain weight was positively correlated with harvest index, while biomass dry weight was negatively correlated. These results suggest that all observed morphoagronomic traits except biomass dry weight have an important role in increasing rice yield. Furthermore, the results of this study provide basic informations for the development of high-yielding rice varieties.

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

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

Kepulauan Seribu have diverse biodiversity, one of which is macroalgae located in the Tourism Utilization Zone and the residential zone. Environmental factors, such as substrate, water quality and the presence of human activities, are very different on each island. The purpose of this study was to determine the differences in the composition and structure of macroalgae communities on islands in the Tourism Utilization Zone, Semak Daun Island and islands in the Settlement Zone, Pramuka Island. Settlement Zone, Pramuka Island. The method used is a quadrat transect. 16 types of macroalgae were found on Semak Daun Island and 26 types of macroalgae on Pramuka Island. The diversity value on Semak Daun Island is categorized as moderate with a value of 1.84 and on Pramuka Island is categorized as moderate with a value of 2.64. The highest INP value on Semak Daun Island is Sargassum binderi and the highest INP on Pramuka Island is Halimeda macroloba.
