Abstract

Temajo Island is renowned for its marine tourism activities and is home to a range of organisms, including algae. Microalgae serve as indicator species, offering insights into the aquatic environment through their species composition and abundance. This study aims to provide preliminary data on the abundance and some ecological indices (diversity, evenness, and dominance) of microalgae on Temajo Island, which will be the basis for assessing water conditions and supporting conservation efforts and sustainable management of natural resources. The research was carried out at four stations with different characteristics. At each station, surface water samples were collected using a plankton net. The microalgae in these samples were subsequently examined under a microscope, and their quantities were measured. The microalgae abundance ranged from 2.84 to 7,697.14 ind/L, with an average of 193.34 ind/L. Chaetoceros was the most abundant genus, followed by Rhizosolenia, Guinardia, Thalassiosira, Pseudo-nitzschia, and Bacteriastrum. The diversity index (H’) ranged from 2.67 to 3.08, indicating moderate to high species richness, while the evenness index (E) ranged from 0.64 to 0.74, reflecting a high level of uniformity among microalgae populations. The dominance index (C) varied between 0.11 and 0.20, suggesting low dominance by any single genus. These indices collectively indicate a balanced and diverse microalgae community, underscoring the ecological health and stability of the Temajo Island waters. Preliminary information about the species composition and abundance of marine microalgae in this study provides valuable insights into the dynamics of microalgae populations and their ecological implications in the marine ecosystems of Indonesia.

Abstract

Glutathione (GSH), is one of the essential antioxidants to prevent free radicals and support the immune system. The low level of glutathione is associated with some diseases such as cancer, Alzheimer's, Parkinson's, and AIDS. Lactic acid bacteria (LAB) can produce glutathione. Indonesia, as a mega biodiversity country, has various vegetables and LAB sources that remain underexplored. This research aims to explore LAB-producing glutathione from fermented products derived from Indonesia's typical plant, the keciwis leaf. The method of this research includes sample preparation, lactic acid bacteria isolation, secondary metabolite production with cysteine precursor addition, glutathione analysis by Ellman's assay, identification of 16S rRNA gene of lactic acid bacteria, and glutathione qualitative analysis by HPLC.  Fermented keciwis leaf-based products contain lactic acid bacteria with positive gram characteristics, can produce 0.33 – 0.37 mM extracellular glutathione. Precursor cysteine addition significantly increases glutathione (p<0,05). The selective lactic acid bacteria producing glutathione was identified as belonging to the genus Weissella, with a similarity value of 98.50%, closely related to Weissella paramesenteroides. Extracellular glutathione produced by this culture showed qualitative results on HPLC with a retention time of 6.34 minutes, indicating the presence of the sulfihydryl group. This study identified a new Indonesia source of lactic acid bacteria of Indonesian–origin lactic acid bacteria, specifically Weissella paramesenteroides, as a promising source for glutathione production

Abstract

The Nyctixalus margaritifer frogs is a native species on Java island, and nature's existence is increasingly threatened. This species has very limited distribution in West Java, and there is no information regarding sexual dimorphism. Therefore, this research aimed to explore the presence of N. margarite in the Situ Gunung area in the Gunung Gede Pangrango National Park (TNGGP) and analyze sexual dimorphism based on morphometrics. The research was conducted in September-December 2023, and data were collected using the Visual Encounter Survey (VES) method. The coordinates of individual N. margaritifer were recorded using GPSMAP, followed by analyzing 23 morphometric characters using the non-parametric Mann-Whitney. The Principal Component Analysis (PCA) was carried out to determine characters that form group structures. The data obtained were tested using the Bartlett homogeneity variance test and declared significant at p-value <0.05. The statistical analysis was performed using R software. The results showed that there were 6 males and 10 females of N. margaritifer in 4.34-hectare home range found at 10-80 cm height from the ground, attached to the leaves or stems of fern Shillaginella sp., taro Homalomena sp., Cyrtandra sp., and Laportea sp. Regarding defensive behavior in the presence of humans, N. margaritifer were observed to stop moving and making sounds, pressed their limbs on the perches, remained still, and appeared dead. The results of the analysis obtained three characters that differentiate sex with significant p-value <0.05, namely snout-vent length (SVL), third toe length (T3), and wrist width (Lt.M). PCA scatter plot showed that the three characters did not contribute maximally as separators. Meanwhile, the K mean cluster analysis produced clustering of SVL, T3, and Lt.M, which was not strong enough to be used as sex-distinguishing characters.

Abstract

The utilization of bajakah tampala (Spatholobus littoralis Hassk) as a herbal medicine has been passed down through generations within the community in Kalimantan. However, no comprehensive studies have investigated the effects of consuming this herbal medicine without a standardized safe dose. This study aimed to determine the spleen microanatomy after administration of an acute dose of S. littoralis stem ethanolic extract. The stems of S. littoralis utilized in this study were obtained from the Sungai Ambawang Forest in Kubu Raya, West Kalimantan. These stems underwent maceration with 96% ethanol solvent. This study used a completely random design with four treatments, which included distilled water and S. littoralis stem ethanolic extract at three doses: 300; 2000; and 5000 mg/kg BW. Each treatment had five replicates. The results showed that the administration of extract doses above 2000 mg/kg BW caused a significant decrease in the diameter of the splenic white pulp, and the spleen’s microanatomy revealed that the boundary between the periarteriolar lymphoid sheaths (PALS) and the lymphoid follicles disappeared, as well as lymphoid follicles that shrank in size. This shows that the administration of extract doses above 2000 mg/kg BW causes symptoms of damage to the spleen microanatomy of experimental animals.

Abstract

Various feeds are widely used to increase egg productivity in the Central Java duck-intensive farming system. However, the proper composition and nutrition in the feed are still debatable. This study aims to analyze the applied feed composition and nutritional content related to duck egg quality from intensive Central Java farms. This research is an observational, exploratory survey involving duck farms in five egg duck production centers, including Semarang, Temanggung, Magelang, Pati, and Salatiga regions. The feeds and 10 duck egg samples were collected from each farm to identify the raw nutritional content and quality. The result showed that the duck feed composition differs depending on the abundance of local resources and farmers' knowledge. Duck farms in coastal areas mainly use fishery products, including small rough fish and dried shrimp waste, while farmers in highland areas prefer to use commercial feed.  Farmers in all regions often supplement their diets with additional feed, such as water spinach, rice bran, snails, wrinkles, and weeds, for varying durations from every day to once a week. Meanwhile, the best feed nutrition was identified from Temanggung, which uses concentrate feed as the main diet, which is composed of sweet corn, soy, and bran. The feed has a balance of raw protein around 24.19 ± 4.11% and 2500 to 2700 kcal calories. The egg productivity in the Temanggung farms also produces high egg production with larger sizes compared to duck farms from other regions. Furthermore, corn and soybeans in duck feed may increase antioxidant activity in yolk significantly, better than shrimp waste.

Abstract

Aglaonema 'Ruby' is a hybrid Aglaonema with a dominant green leaf pattern and a red accent in the middle. This cultivar is widely cultivated and in great demand, and it can potentially be used in micro floriculture development. Conventional Aglaonema propagation through stem cuttings can only produce 1-3 shoots. Therefore, the in vitro culture method is proposed. The objectives of this study were to evaluate the effect of three synthetic cytokinins (BAP, Kinetin, and TDZ—the latter being a phenylurea derivative with cytokinin-like activity) and concentrations on the multiplication of Aglaonema 'Ruby' microshoot. The research has been carried out experimentally using a split-plot design. The main plot was cytokinin types, consisting of BAP, Kinetin, and Thidiazuron; the subplot was cytokinin concentrations at 0, 5, 10, 15, and 20 µM. The measured parameters include shoot emergence time, number of shoots, leaves, and shoot length. The data were analyzed using an analysis of variance (ANOVA) followed by Duncan's multiple range test at 95% confidence level. It can be concluded that the growth of Aglaonema 'Ruby' micro shoots was controlled by the type and concentration of cytokinin given. Thidiazuron was better than Kinetin and BAP in stimulating the growth of Aglaonema 'Ruby' microshoots. Cytokinin at 10 µM seemed to be effective in improving Aglaonema 'Ruby' micro shoots multiplication. Thidiazuron at 10 µM can increase the production of Aglaonema 'Ruby' shoot to support both mass production of seedlings and microfloriculture products. Further studies are needed to optimize shoot and root development to produce good plantlets, easing the subsequent acclimatization.

Abstract

The increasing use of inorganic fertilizers is one of the main factors contributing to increased Cadmium (Cd) pollution in the environment. Phytoremediation is one of the strategies that can be used to address the problem of Cd pollution in the environment. The selection of Cadmium-tolerant plants can be conducted using an in vitro culture. Talinum paniculatum as an ornamental plant is potentially used as a phytoremediation agent, but limited information is available regarding its accumulation ability and tolerance to cadmium stress. Therefore, this study aims to determine the accumulation ability and tolerance of T. paniculatum callus to cadmium at various concentrations. This study used a completely randomized design (CRD) with six replications of Cd concentration treatment (0, 5, 10, and 20 ppm). Accumulation and tolerance of callus to Cd were assessed based on callus biomass, callus color, tolerance index, heavy metal concentration in callus and media, and Bioconcentration Factor value. An increase in Cd concentration showed a change in callus color from yellowish green to blackish. In addition, there was no significant difference in dry weight (0.078-0.086 g) and tolerance index (102.631%-113.158%) of callus. However, increasing Cd concentration showed significant differences in callus Cd accumulation from media (5-20 ppm) and Bioconcentration Factor (BCF) ratio (1.282-5.701), indicating the ability of T. paniculatum as an accumulator plant. This study's results support phytoremediation efforts against heavy metal pollution, including cadmium.

Abstract

Research to estimate carbon absorption using ecosystem productivity models carried out in riparian zones is still rare. This research aims to determine the carbon and biomass potential in the Brantas River riparian zone, Batu City. The data obtained was retrieved using Microsoft Excel 2013 software. The data was tested differently using Paleontological Statistics, through normality and homogeneity tests, and continued with a different test. Different tests are carried out to determine the quality of the riparian zone between the observation stations. In addition, the Principal Component Analysis (PCA) is continued with Biplot and Cluster Analysis to understand the differences between the stations and to know the characteristics between stations. The biomass in the village of Sidomulyo is bigger than any other location. The biomass is about 8760 tons/ha with a carbon potential of 4380 tons. This value is very high compared to the entire location. The average potential carbon at each location ranges from 67 to 285 tons. Sidomulyo village's riparian zone, rich in carbon and biomass, requires preservation to prevent global warming due to carbon emissions. The closure of land at the site of the village of Sidomulyo did not cause the riparian zone in the village to become less. The results showed that although the village of Sidomulyo has a savage land cover and settlements, the carbon storage from trees in the riparian zone is huge. This research aids in developing conservation strategies for riparian zones with high carbon storage potential, supports climate change mitigation, and informs policymakers on sustainable land management practices in the Brantas River watershed.

Abstract

Bandealit Resort is a conservation area encompassing diverse habitats, providing a suitable environment for dragonflies to thrive as permanent inhabitants. The region plays a crucial role in supplying vital water for the life cycle of dragonflies. Human activities occurring in the upstream areas, such as agriculture, can potentially deteriorate water quality due to pollution. This work is highly significant due to the lack of recent monitoring data on dragonflies in the area and the pivotal role of dragonflies as bioindicators. This study aimed to analyze the composition and organization of the dragonfly population at Bandealit Resort (MBNP). A total of twelve dragonfly species were documented, among which were two species that are exclusive to Java. The Shannon-Wiener index study indicated a classification of modest diversity. The Terjun Block had the highest dominance index (D) of 0.27, whilst the Pringtali Block had the highest uniformity index (e^H/S) of 0.86. The species with the most excellent importance index (IVI) in different blocks are as follows: Euphaea variegata and Vestalis luctuosa in Pringtali Block, Nososticta insignis in Terjun Block, and Crocothemis servilia in East Muara Block. The canonical corresponding analysis (CCA) revealed that V. luctuosa, Heliocypha fenestrata, and Nososticta insignis exhibited a correlation with air humidity. In contrast, Copera marginipes, Pantala flavescens, C. servilia, and Diplacodes trivialis demonstrated a correlation with light intensity, wind speed, and air temperature. This research holds significance as it directly examines the relationship between dragonfly communities and abiotic parameters within the Bandealit Resort, Meru Betiri National Park (MBNP).

Abstract

Mangrove forests are declining significantly. Hence, artificial rehabilitation through plant seedlings is necessary. However, failure often occurs due to the low quality of available seedlings. One solution to improve the seedling's quality is the application of growth regulators during mangrove rehabilitation. This study aimed to examine the effect of natural plant growth regulators, namely coconut water and V. radiata extract, as well as the synthetic plant growth regulator root up on the growth of Brugueira  gymnorrhiza seedlings. The research method employed was a Completely Randomized Design (CRD) with a single factor consisting of four treatments and five replications, as follows: P0 = Control, P1 = 100% coconut water, P2 = 10% root up, and P3 = 100% Vigna radiata extract. The observation parameters included plant height, number of leaves, root length, number of roots, stem diameter, and wet weight. Data analysis was conducted with ANOVA and Duncan's Multiple Range Test., natural plant growth regulators (PGRs) considerably improved the growth characteristics of Bruguiera gymnorrhiza seedlings compared to the control and synthetic PGR treatment (Root-Up) (p < 0.05). Among the treatments, Vigna radiata extract had the most impact, with the maximum plant height (51.2 cm), stem diameter (15.264 mm), number of roots (10.6), and fresh weight (33.8 g). Furthermore, the application of coconut water resulted in a considerable rise in the number of leaves, reaching an average of 5.8, as well as increased root elongation with an average length of 10.188 cm. In contrast, using root up at a 10% concentration resulted in no statistically significant improvement in any of the evaluated metrics.
