Abstract

Tulehu waters in Central Maluku have reportedly experienced a decline in the quality and variety of biota. Sources of pollution, including the heavy metal Chromium, are thought to have increased over time in this area. Chromium is a dangerous, toxic metal that is highly soluble and has wide mobility in nature. Pollutants that decompose in waters and settle in sediments affect the amount of uptake and sustainability of mangrove plants. The aim of this research is to determine the distribution pattern of the heavy metal Chromium during 3 measurement periods in Tulehu Waters, Central Maluku. This research was conducted on 16 May – 16 July 2024. The sampling method was carried out in three sampling periods at three observation stations. The measurement interval is 15 days. Testing for the heavy metal Chromium was carried out on water, sediment and mangrove organs using an Atomic Absorption Spectrophotometer (AAS). The results of the research show that the levels of the heavy metal Chromium in Tulehu waters fluctuated during the three observation periods and were still below the predetermined threshold, so they have not affected the life of mangrove biota but are threatening if preservation measures are not taken by the government and surrounding communities.

Abstract

Indonesia is recognized as a country with high biodiversity, particularly in terms of flora and fauna, with approximately 17% of the world’s total species found within its borders. One of the most significant aspects of this biodiversity is the presence of medicinal plants, which have been traditionally used by Indonesian communities to treat various diseases, especially chronic and degenerative illnesses. Previous studies conducted in Indonesia have identified 65 species of medicinal plants from 38 different families, with a large proportion belonging to the Zingiberaceae (12.3%), Euphorbiaceae (7.6%), and Poaceae families. Most of these plants are sourced from forests, and Indonesian communities primarily use their leaves for herbal medicine. These traditional herbal remedies have been reported to treat 38 different diseases (Meliki & Lovadi, 2013). This study identifies 22 species of medicinal plants utilized by the residents of Sumberbrantas Village, who possess ancestral knowledge regarding their use. The research employed semi-structured interviews with 70 respondents, selected using the Snowball Sampling technique. The findings reveal that the following plants are commonly used: Allium sativum (Garlic), Amaranthus blitum (Slender amaranth), Annona muricata (Soursop), Apium graveolens (Celery), Beta vulgaris (Sugar beet), Coleus scutellarioides (Miana), Cosmos caudatus (Ulam raja), Curcuma longa (Turmeric), Cymbopogon citratus (Lemongrass), Ipomoea batatas (Sweet potato), Kaempferia galanga (Aromatic ginger), Mesona chinensis (Black grass jelly), Morinda citrifolia (Noni), Ocimum basilicum (Basil), Orthosiphon aristatus (Cat’s whiskers), Solanum tuberosum (Potato), Syzygium polyanthum (Indonesian bay leaf), Alpinia galanga (Greater galangal), Brassica oleracea (Broccoli), and Daucus carota (Carrot). Despite the increasing popularity of modern medicine, education and awareness regarding the benefits of medicinal plants should be emphasized to preserve local knowledge and promote awareness of traditional medicine’s potential. This study highlights the need for ethnobotanical documentation to support biodiversity conservation and the development of plant-based medicines in Indonesia.

Abstract

The aim of this study was to evaluate the impact of mycorrhizal applications of Glomus sp., Trichoderma harzianum species, and organic biofertilizers on the growth parameters and productivity of corn (Zea mays L.). This experiment was conducted in the period of May-July 2012 on agricultural land located in Kendal Village, Kendal District, Ngawi Regency. The applied methodology was a completely randomized design (CRD) with four treatment groups; (1) the control group, (2) the Glomus sp. mycorrhiza group as much as 30 g/plant, (3) the T. harzianum group as much as 30 ml/plant, (4) the biological fertilizer group as much as 5 ml/plant with each treatment repeated five times. Data related to plant growth and production were analyzed using the Analysis of Variance (ANOVA) test, with the Duncan test at a significance 5% to determine significant differences between treatments.. The results from the four treatments show that the application of Glomus sp., T. harzianum, and organic biofertilizers have a significant effect (α < 0.05) on the growth and yield of corn. T. harzianum treatment produced the highest plant height, which was 181 ± 8.9 cm, while the application of Glomus sp. mycorrhiza gave the best contribution to root length parameters with an average of 41.2 ± 5.3 cm. The application of biofertilizer also provides an optimum result for corn weight of 144 ± 28.9 g

Abstract

Gambier leaves (Uncaria gambir) are a primary source of bioactive compounds, particularly catechins, which have high potential for therapeutic applications due to their antioxidant activity. This study aims to investigate the isolation process of catechins from gambier leaves, determine the catechin content, and evaluate the antioxidant activity of the isolated compound. The research methodology includes maceration of gambier leaves using 96% ethanol as a solvent, isolation using chromatography, catechin content analysis using HPLC, and antioxidant activity assessment using the DPPH (2,2-diphenyl-1-picrylhydrazyl) method. The results indicate that catechin isolates were successfully obtained from gambier leaves through chromatographic separation. Optimal separation was achieved using an N-hexane:ethyl acetate (2:1) mobile phase. The catechin content in the gambier leaf isolate was 129.99 ppm, while the antioxidant activity test showed an IC50 value of 25.2 ppm, indicating very strong antioxidant activity. Catechins from gambier leaves have great potential as a natural antioxidant source due to their high free radical scavenging activity.

Abstract

Water hyacinth (Eichhornia crassipes) is a widespread aquatic weed in tropical and subtropical regions, which has caused various environmental problems. This study aimed to observe and describe the morphological characteristics of water hyacinth from the waters of Cilacap. The methods used were field observations and analysis of water hyacinth plant samples. The morphological parameters measured included leaf length, petiole length, and root length. The results showed that the average leaf length of water hyacinth in Cilacap was 14 cm, petiole length was 24 cm, and root length was 26 cm. A total of 30 individuals were sampled in this study, with leaf lengths ranging from 10 to 20 cm, petiole lengths ranging from 20 to 28 cm, and root lengths ranging from 22 to 30 cm. These values are consistent with previous reports on the morphology of water hyacinth in tropical waters. This study is important because the environmental conditions of Cilacap waters, such as an average water temperature of 28°C and a water pH of 7.2, can affect the local growth of water hyacinth. The results of this study provide an overview of local morphological variations and can be used as a basis for the management and control of water hyacinth in Cilacap waters.

Abstract

This study characterizes the morphology and analyzes the phylogenetic relationships of five local banana varieties found around Purwokerto area, Central Java (wild, ulin, mas, raja, and ambon) by means of observation on nine qualitative traits and UPGMA (Unweighted Pair Group Method with Arithmetic Mean) analysis. The results reveal morphological variations among the five banana varieties, especially with respect to three main characters, i.e. fruit shape (curved/straight), presence of seeds (present/absent), and bunch surface (hairy/hairless). The wild banana exhibits typical wild morphological characteristics (angled seeds, hairy bunches), while the four cultivated varieties show domesticated features (seedless and hairless bunches). UPGMA analysis shows that ambon, raja, mas, and ulin cultivars are grouped into a single cluster, indicating morfological similarity and a possible close genetic relationship, while wild banana lies as an outlier, indicating sufficiently high morphological differences from the four cultivars.

Abstract

Orchids are one of the plant groups with abundant species diversity and make a significant contribution to ecosystem functions. Their morphological beauty and high economic value make orchids highly sought after, but this has led to excessive exploitation by the public. One of the rare orchids with important conservation value is the genus Phalaenopsis, or moon orchid, known for its unique characteristics, such as varied colors and patterns. To identify Phalaenopsis, an appropriate method is required, one of which is DNA barcoding. This study aims to analyze the phylogenetic relationships of the Phalaenopsis genus using the matK, rbcL, and ITS gene sequences in silico. The method used is an in silico study utilizing the GenBank database (NCBI). DNA sequences were collected from NCBI by searching for species names and related genes, namely matK, rbcL, and ITS. The collected data were then analyzed using CLUSTAL W to evaluate the similarity between sequences through alignment, identify sequences with potential as barcodes, and reconstruct the phylogenetic tree using MEGA 11. The results showed that alignment with the matK, rbcL, and ITS loci yielded a sufficiently high level of similarity. However, the ITS gene provides more detailed information about the topology of the molecular phylogenetic tree at the species level compared to the matK and rbcL genes. Additionally, the ITS gene can reveal specific characteristics of Phalaenopsis, indicating its potential as a DNA barcode.

Abstract

Kombucha is a fermented probiotic drink made from sugar with the help of Symbiotic Consortium of Bacteria and Yeast (SCOBY). This study aims to determine the phytochemical profile and antibacterial activity of kombucha of Palmyra palm mesocarp (Borassus flabellifer) against Propionibacterium acnes, the main cause of skin acne. The research method used a complete randomised design (CRD) with 7 and 14 days of fermentation. Phytochemical test was conducted qualitatively to identify flavonoids, tannins, saponins, and alkaloid compounds. Meanwhile, the disc diffusion method was used to test the antibacterial activity of Palmyra palm mesocarp kombucha against P. acnes. The results showed that Palmyra palm mesocarp kombucha contained all the phytochemical compounds tested, with flavonoids only detected at 14 days fermentation and the alkaloid content was higher at 14 days fermentation. The highest antibacterial activity was obtained in 14-day fermented kombucha with an average inhibition zone diameter of 36.9 mm and categorized as very strong, equivalent to the positive control in the form of chloramphenicol. The flavonoid and alkaloid contents is thought to play a role in inhibiting bacterial growth. Thus, kombucha of Palmyra palm mesocarp has the potential as a natural antibacterial agent in the treatment of acne caused by P. acnes.

Abstract

Tree ferns of the family Cyatheaceae play an important role in maintaining the ecological balance of tropical montane forest ecosystems and are known for their sensitivity to microenvironmental variation. This study aimed to explore the species diversity and altitudinal distribution of Cyatheaceae in the lower montane rainforest of Curug Cipendok, located on the southern slope of Mount Slamet, Central Java, Indonesia. Field surveys were conducted using purposive sampling across three elevation zones (700–800 masl, 801–900 masl, and 901–1,000 masl). A total of six species comprising 396 individuals were recorded: Alsophila borneensis, A. firma, Cyathea aspera, C. schiedeana, Sphaeropteris glauca, and S. horrida. Species composition varied with elevation, with the highest diversity index (H’ = 1.722) found at mid-elevation. Morphological variations in trunk, fronds, and sori provided significant diagnostic information for taxonomic identification.

Abstract

Polystyrene is a type of plastic that is difficult to decompose naturally and  one of the main causes of environmental problems, especially in Indonesia, styrofoam waste in 2023 reached more than 32 million tons per year. This study uses quantitative descriptive and experimental methods to determine the ability of Bacillus subtilis bacteria to decompose polystyrene waste. The quantitative descriptive method was carried out by measuring the decrease in dry weight of polystyrene, while the experimental method was carried out by incubating 1x1 cm and 2x2 cm polystyrene samples with B. subtilis in Bushnell Haas media at 37°C for 40 days, with observations performed every 10 days. In addition, chemical changes in polystyrene were observed using Fourier Transform Infrared (FTIR) to see changes in functional groups. The results showed that the 1×1 cm sample experienced a weight loss of up to 20.65% after 40 days, while the 2×2 cm sample only decreased by 8.70%. FTIR analysis showed changes in absorption intensity and the appearance of carbonyl (C=O) and hydroxyl (O–H) groups, indicating the occurrence of oxidation and polymer chain cleavage. In conclusion, Bacillus subtilis was able to degrade polystyrene gradually, with effectiveness influenced by the size of the sample surface and the length of incubation time.
