Abstract

The establishment of Taman Kehati Asri by PT Chandra Asri is a form of protection of biodiversity to improve the quality of biodiversity, including fauna. The existence of fauna is very important in ecosystem activities because fauna is a consumer in the food pyramid. If a population decreases, it will have a negative impact on the continuity of food webs and hinder the flow of energy cycle. This study aimed to identify the diversity of fauna in the Taman Kehati Asri area of PT. Chandra Asri Petrochemical, in Gunung Sugih Village, Ciwandan District, Cilegon City, Banten. The research was conducted in October 2022. The methods used were point count and cruise method. Based on the research results, it was found that there were 37 species of fauna belonging to 4 classes, namely birds, mammals, herpetofauna and insects. The result of total species diversity index was 2.98 which was categorized as in the medium category. Furthermore, the fauna dominance index was 0.075 which indicated that one or several species of fauna were not dominated in that area.

Abstract

Urban forest is a special area in anurban planning that plays a role in preserving the environment, as a recreation area and as one of the lungs of the city which helps in maintaining the health of city air. The existence of ants in the urban forest plays a role in maintaining the stability of the urban forest ecosystem which generally has both open and closed habitats. The purpose was to provide information regarding the description of ant species in open and closed habitats in the urban forest of the Cibubur Arboretum, East Jakarta. This research was conducted in the Cibubur Arboretum City Forest, East Jakarta. Sampling was carried out from 5─12 December 2022 using a pitfall trap which was placed in each habitat with a distance between traps of 5 m. As many as 14 ant species are tramp ants which have high adaptability to environmental disturbances. Of the 14 species found, 12 species were not found in closed habitats, namely, Camponotus arrogans and Polycharis becarrii. Pheidole parva was found in open habitats, meanwhile, in closed habitats, Odontoponera denticulata was found in the highest number.

Abstract

Jabon (Neolamarckia cadamba (Roxb.) Boser.) is commonly planted for many purposes, such as furniture, raw material for industries, and land rehabilitations. Eventhough this tree has no significant pests and diseases, weed control treatments are required. Many weed control treatments are known to affect vegetation structure of weed. Thus, the objective of this study was to examine the effect of weed control treatments to the vegetation structure of weed under Jabon plantation. This study was conducted in Kecamatan Tanah Putih Tanjung Melawan, Kabupaten Rokan Hilir, Riau Province in 2012. Non Factorial Randomized Group Design with five replications was applied to perform the study. There were four treatments (glyphosate, paraquat, mixture of glyphosate and paraquat, and legume cover crop/LCC) and control. The results revealed that glyphosate and paraquat had the highest value in surpressing the weed growth as much as 34,45% and 31,11% (P>0.05) after one month application. Yet, after three months, LCC was significantly surpressed the number of weed (49,44%) (P<0.05) compared to other treatments. Among all weed species, Blumea sp. was the dominant species after one month of glyphosate and paraquat application. Nevertheless, application of glyphosate-paraquat mixture and LCC resulted Ottochloa nodosa as the dominant species after one month application.

Abstract

Antibiotic resistance is one of the main challenges faced by the health world today. Therefore, various efforts are being made to find new alternative antibiotics from various sources. Endophytic bacteria from medicinal plants are thought to have an antibacterial activity that can potentially inhibit pathogenic bacteria growth. This study aimed to isolate and characterize endophytic bacteria from the Dayak onion plant and determine their potential to inhibit the growth of two pathogenic bacteria Escherichia coli and Staphylococcus aureus. Bacterial isolation was carried out using the surface sterilization method and grown on nutrient agar media. The endophytic bacteria isolates obtained were then characterized macroscopically and microscopically. The agar plug diffusion method carried out the antagonism test against pathogenic bacteria. The result showed that 40 isolates of endophytic bacteria were successfully isolated from the Dayak onion plant's leaves, bulbs, and roots. Based on the antagonism test, 3 isolates were able to inhibit E.coli while 8 isolates were able to inhibit S. aureus. Three isolates (CED3, CED4, and CEU6) were able to inhibit both pathogenic bacteria, and the highest activity was shown by CED3 isolates.

Abstract

A study has been carried out to compare the expression of miRNA-21 and miRNA-143 with target mRNA PDCD4 and BCL-2 in cases of early-stage cervical cancer compared to advanced stages. These data can be used as information for the development of non-invasive cervical cancer prognostic methods. The study was conducted by taking serum samples and exfoliativecell samples from normal subjects and subjects with cervical cancer detection and then analyzed using qRT-PCR. Samples of cervical cancer patients consisting of 15 subjects and 4 normal subjects were used to obtain relative quantity values for the expression of miRNA-21, miRNA-143, mRNA PDCD4 and BCL-2. In the study of miRNA-21, there was no significant difference in determining cervical cancer with p>0.05 using the t-test (0.594) and a significant relationship was found between miRNA 21 and PDCD4 with a strong correlation (p<0.05, r = -0.563; Pearson). The relationship between miRNA-143 and the Bcl-2 target gene in this study showed a weak and insignificant correlation (r = -0.101; p > 0.05; Pearson). There was a significant relationship between miRNA-21 and PDCD4 in early-stage and advanced-stage samples, while the relationship between miRNA-143 and the Bcl-2 mRNA target gene showed no significant correlation.

Abstract

Plant anatomy is one of the important basic data to reveal the potential of a plant. Anatomical data provide an overview of the internal structure of the plant body. This structure is influenced by the environment, the same thing is also likely to occur in Komak kedit plants which are widely planted on Lombok Island. Komak kedit (Phaseolus lunatus L.) is a species of legume (Fabaceae) originating from Central America. The purpose of this study was to analyze the differences or variations in the anatomical structure of the Komak kedit (P. lunatus) on Lombok Island. Data analysis in this research was descriptive qualitative and triangulation. The results showed that the anatomical structure of the roots, stems, leaves, flowers, fruits, and seeds of the Komak kedit plant on Lombok Island had similar structure, such as epidermis, cortex, and stele. However, in this study, there were more differences in the number of stomata on leaves in West Lombok compared to East Lombok, Central Lombok, North Lombok, and Mataram. This was caused by differences in the environment where the plants were planted, such as water content.

Abstract

This study aimed to determine the diversity of amphibian species in different habitat types along shore of Lake Sipin. This study used a combination of path (Transect) and VES (Visual Encounter Survey) methods. Research area was determined using purposive sampling based on the function of the habitat and the number of prey animals. The population in this study was all amphibians in the Sipin Lake. The samples were all amphibians caught using fishing nets or bare hands. Identification of amphibian species found in the lake used field guidebooks and online-based guide. The results of research carried out along the edge of Lake Sipin showed 215 individuals, 8 species and 4 families were found to be amphibians. The diversity index for amphibian species generally shows an H' index with an H' value of 1.19, which is included in the medium diversity index value. The overall amphibian species evenness index value is classified as an unstable community (E=0.573) and the amphibian species richness index value generally shows a low species richness index (Dmg=1.303). Meanwhile, the value of the community similarity index or Index of Similarity (IS) generally shows that natural habitats and tourism are relatively high with an index value of 90%.

Abstract

Mangrove is a unique vegetation type growing along the coastline and estuarine in tropical and subtropical countries. Mangroves in Indonesia are distributed in all major islands and small islands from Aceh on westside stretched to Papua on the east. This study is to monitor the mangrove area in Poto island a small island part of Kabupaten Bintan, Province of Riau Kepulauan. The difference in spatial resolution of remote sensing data Sentinel 2A and Pleiades were used to classify the land use including the mangrove area. The supervised classification by maximum likelihood classification showed the high-resolution image using Pleiades has higher accuracy for mangroves 81.99% and overall accuracy 90% (kappa 0.86) compared to Sentinel 2A for mangrove 72,34% and overall accuracy 80% (kappa 0.73). The mangrove area approximately 257 ha is strip-lining along the coastline with the largest mangrove area located on the southside of the island. Further research is to identify the mangroves’ formation and the serial condition of mangroves on the different times.

Abstract

The main mode of communication in Anura is acoustic signals, but environmental noise can hinder effectiveness signal transmission and reception. The adaptation to noise is by visual signals. This study was conducted to determine the density, the type of visual signals detected, and whether there is an influence of environmental noise and conspecific density on the prevalence of Leptophryne borbonica population displaying visual signals. This study was conducted by descriptive method with purposive sampling technique. The data taken was in the form of the number of individuals with visual signals, the number of individuals vocalizing, and the noise of the surrounding environment. The data was processed using the Solomon Coder and analyzed by Poisson regression. 159 individual frogs were found in 40 plots during observations, with the density of individuals in each plot being 3-8 individuals with noise range of 45-74 dB. Noise significantly affected the display of visual signals in a population, while conspecific density did not affect the output of visual signals.
