Abstract

Indonesia is rich in diversity of medicinal plants, vital in traditional medicine and the pharmaceutical industry. However, overharvesting, along with population growth, land use changes, deforestation, and climate change, endanger these plants. This review investigates the potential of endophytic endosymbiont as an alternative. These endosymbionts can synthesise bioactive compounds similar to those found in medicinal plants.  This study compiled data from various sources on endophytic fungi and their bioactivity. The review aims to categorise Indonesian medicinal plants, to identify their associated endophytic fungi from different plant parts, and to assess their bioactivity. The results revealed numerous medicinal plant families and a variety of endophytic fungi isolated from fruits, leaves, twigs, bark, roots, and rhizomes. These fungi exhibited bioactivities, including antioxidant, anticancer, antidiabetic, and antimicrobial effects, with metabolites such as alkaloids, flavonoids, peptides, phenols, polyketides, quinones, steroids, and terpenoids. Fusarium and Colletotrichum were the most common endophytic fungi found. Notably, the biological activity was consistent among endophytic fungi from various host organs, but variations were observed according to the host's geographical origin. This suggests that Indonesia's diverse geography influences metabolite production and activity. However, the same host plant may harbour different species in distinct organs. These findings indicate that endophytic fungi within medicinal plants represent a promising source of bioactive compounds for future Indonesian medicine production. Future research should explore metabolite compounds and bioactivity across different geographical regions.

Abstract

Mangosteen (Garcinia mangostana L.) is a tropical fruit that has become a sought-after commodity by enthusiasts from various countries, including Indonesia. The active components found in mangosteen peel primarily consist of active xanthone compounds, such as mangostenol, mangostin, mangostino A, mangostino B, tvophylin B, trapezifolixanthone, alpha mangostin, beta mangostin, garcinon B, mangostano, as well as flavonoids epicatechin and gartanin. These compounds exhibit a range of beneficial properties, including anti-inflammatory, antibacterial, antifungal, antihistamine, antidiabetic, anticancer, and more. Consequently, there is significant potential in developing mangosteen peel extract as a valuable ingredient in herbal medicine. However, there is currently no available data on the effects of exposure to mangosteen peel decoction on fish animal models. Therefore, it is essential to investigate the impact of mangosteen peel decoction on wader pari fish (Rasbora lateristriata) embryos. In this study, wader pari embryos were subjected to various concentrations of mangosteen peel decoction (0.5, 1, 5, and 25 µg/mL). The effects on egg hatchability, survival rate (SR), heart rate frequency, and heart morphology of the larvae were meticulously examined using a Leica microscope. The data obtained were subjected to statistical analysis using one-way ANOVA. The findings demonstrated that exposure to mangosteen peel decoction resulted in lower hatching rates and embryonic survival, alongside an increased heart rate frequency. Additionally, the exposed embryos displayed cardiac edema and cardiac bending, particularly at the concentration of 25 µg/mL. In conclusion, the exposure of wader pari fish embryos to mangosteen peel decoction at the concentrations of 25 µg/mL and higher significantly affected the hatching rate, survival rate, and heart rate of R. lateristriata fish larvae.

Abstract

Purworejo Regency is located in the south coast of Java where rivers flow into the Indian Ocean. The Jali River in Purworejo becomes a migration route for eels where juvenile eels (glass eels) move from the ocean to freshwater passing through the estuary. During migration, glass eels will make efforts to survive, one of which is to manage their osmotic pressure (osmolarity). With regards to those, a study on the upstream migration of glass eels in Jali River was carried out. Glass eels samplings were conducted using hand-held lift nets at the new moon phase, from 20:00 pm to 4:00 am. Sampling stations included the estuary, a branch river, and below the dam. The osmolarity of both glass eels and media (river water) were measured. Furthermore, the chemical and physical parameters of the waters as the natural habitat for glass eels were also measured. Glass eel samples were then identified to species level. The results showed that glass eels entering the Jali River consisted of Anguilla bicolor bicolor and Anguilla nebulosa nebulosa with the former being the most common. Total length of glass eels ranged between 44.10 to 69.70 mm with total weights 0.08 to 0.54 g. Glass eel migration has a close relation with surface current and tide. The osmotic work level (OWL) of glass eels approaches 0.34 mOsm/l H2O which is close to iso-osmotic. This happened at salinity 0 o/oo so that the glass eels migrate to fresh water which has a lower salinity to achieve iso-osmotic condition.

Abstract

Increases in the temperature of nutrient solutions have restricted the use of hydroponic cultivation in the tropics, predominantly due to plant stress. This study aimed to evaluate the effects of temperature stress under different hydroponic systems on the growth and saponin content of Talinum paniculatum cuttings. Three hydroponic systems, i.e., deep flow technique (DFT), nutrient film technique (NFT), and aeroponic, were tested. The temperature of the nutrient solution was set for each system, i.e., under ambient temperature (UAT) and with controlled temperature (WCT) at 26° C. The cultivation period was 60 days. The result showed peroxidation activity and proline accumulation for the adventitious roots of T. paniculatum cuttings with UAT and WCT, alongside various levels of plasma membrane damage. Levels of Malondialdehyde (MDA) and proline were analyzed by spectrophotometer. Membrane damage was analyzed with Evans blue dye. The results indicated that the levels of MDA and proline accumulation under the three hydroponic systems were higher for the WCT than for the UAT treatment. In contrast, vegetative growth was higher in UAT than in WCT. The saponin content of the adventitious root correlated with the MDA level. Saponin production was triggered by oxidative stress during cultivation, while the adventitious roots had a higher saponin content in all three hydroponic systems with the WCT treatment compared to the UAT treatment. Among the systems, aeroponic was superior for biomass and saponin. Root growth was promoted in the nutrient solution under ambient temperature whereas the production of saponins was stimulated under the controlled temperature. In the aeroponic system, root biomass values of 1.17 and 0.478 g dry weight were obtained under ambient and controlled temperatures, respectively. The total saponin contents differed slightly, namely 189.83 and 195.61 mg/g, respectively.

Abstract

The distribution of the Reinwardt's Gliding Frog, Rhacophorus reinwardtii (Schlegel, 1840), was recently thought to be restricted in Java. Furthermore, the constant and rapid deforestation in Java highlight the significance of the frog's habitat requirements in establishing the accurate species' conservation status. This study aims to predict the suitable habitat for this species in Java and to identify the habitat characteristics in Malang Region-East Java. Using the Maximum Entropy (MaxEnt) approach, we modelled the distribution of species and examined numerous types of breeding sites in Malang Region. Our findings revealed that the species inhabits a much more restricted and fragmented habitat in Java, where it inhabits both forest and agroforestry areas.

Abstract

Ulva lactuca is a macroalgae that contains high nutritional values. The heavy metal contaminants in natural Ulva lactuca needs to be eliminated or decreased using natural agent. The aim of this research was to determine the bioaccumulation of Pb, Cd, Hg, and the impact on liver and gastrointestinal function. Parameters of this research were Hepatosomatic Index (HSI), SGPT levels, SGOT levels, bioaccumulation Pb, Cd, Hg, and histological structure of liver and small intestine. Besides that, the progression of body weight was observed. Twelve female Wistar rats (Rattus norvegicus Berkenhout, 1769) were randomly assigned to three groups: Control, NU (treated with natural Ulva lactuca), and DU (treated with heavy metal decontaminated Ulva lactuca using Averrhoa bilimbi juice).Treatment was carried out orally at a dose of 1000 mg/Kg BW/day for 30 days. Histological structure of rat’s liver and small intestine were prepared after necropsy at the end of this research. Based on results, it can be concluded that there were no significant differences observed in HSI, SGPT, and SGOT levels among the groups. However, there was a tendency for an increase in total bilirubin levels in the decontaminated Ulva lactuca group. Both natural and heavy metal decontaminated Ulva lactuca showed histological damage on liver and small intestine. Bioaccumulation of Cd and Hg in the liver and gastrointestinal tract of rats after consuming decontaminated Ulva lactuca was lower than the natural Ulva lactuca group, but need more observations.

Abstract

Tagetes is a genus consisting of several efficacious plant species known as marigold, which is native to Mexico and has  spread worldwide due to its ability to adapt to different soil conditions. This genus is very popular among gardeners because it’s easy to cultivate, adaptable, produces flowers all year round, has a free flowering habit, short duration, and the flower has an attractive color and shape. It has many flowers of varying colors such as red, orange, yellow, mixed red-orange or red-yellow, but the yellow and orange color are the most popular. The flowers contain many carotenoids, which act as antioxidants, anti-bacterial, anti-inflammatory, anti-carcinogen, nematicide, and cosmetics. The carotenoid can also cure fever, epileptic fits, astringent, scabies, liver complaints, stomachache, sore throat, and  can be used as a natural moisturizer, and natural mosquito repellent Besides its use as a medicinal plant, Tagetes is also used as ornamental plants and edible plants. This manuscript’s endeavour is to include some important investigations and studies about the general description, phytochemicals compounds and essential oils, medicinal uses, natural pesticides, and food and beverage uses of the marigolds.

Abstract

Peatland plays an important role not just as a carbon store but also in facilitating the flux of greenhouse gasses into the atmosphere. Apart from that, peatland is also home to a diverse population of microorganisms such as bacteria, fungi, and actinomycetes. Actinomycetes were known to be one of the most ubiquitous microbes that can be found in most of the soil types including peat soil. In this study, seventy isolates of actinomycetes were isolated from the peat soil using the soil dilution method. The 70 isolates of actinomycetes were later screened for their ability to produce secondary metabolites and antimicrobial activities using the agar diffusion method before the selected potential isolates were identified by targeting their 16S rRNA region. The results obtained showed 34.3% produce cellulase followed by, 12.8, 31.7, 80.0, and 51.4% for mannanase, xylanase, lipase, and protease respectively. The percentage of actinomycetes producing antimicrobial activity was 27.1 and 21.4% for Ralstonia solanacearum and Colletotrichum gleosporioides respectively. All the selected isolates of actinomycetes were identified as belonging to the genus of Streptomycetes spp. The potential actinomycetes were stored in freeze-dried form for future usage. This study showed that  more diverse population of actinomycetes was obtained from the undisturbed forested peat soil area ecosystem compared to the agricultural peat soil area.

Abstract

Indonesian people’s interest in honey, the product from honey bees, is quite high. It caused many cases of honey fraud such as mislabelling the entomological origin of honey. The Major Royal Jelly Protein 2 (mrjp2) gene, which encodes MRJP, can be used to determine the entomological origin of honey. The mrjp2 gene, for example, can be detected in honey from A. mellifera and A. cerana using species-specific primers for A. mellifera (MF-MR) and A. cerana (CF-CR). This study aims to detect the mrjp2 gene in several honey bee species native to Indonesia, namely A. dorsata, A. dorsata binghami, A. florea, A. nigrocincta, A. mellifera, and A. cerana as well as analyse the feasibility of MF-MR and CF-CR primers in determining the entomological origin of honey. The results showed that the MF-MR primers can amplify the DNA of A. dorsata binghami, A. florea, and A. mellifera, while CF-CR primers can amplify the DNA of both A. nigrocincta and A. cerana. The amplicons were subsequently sequenced. The phylogenetic tree and the genetic distance showed that there were differences and variation between each species of honey bee samples with the honey bee database. The data obtained from this research indicated that both primers could not determine the entomological origin of honey directly up to species level. The species level determination will only be possible using sequences information. However, in certain situations, the MF-MR and CF-CR primers were able to differentiate the honey bee species by including the information of the geographical origin of honey sample and the distribution area of each species of honey bees in Indonesia.
