Abstract

Stevia rebaudiana (Bertoni) Bertoni is a perennial herbaceous plant that produces natural low glycemic-index sweeteners alternative to sugar cane. The genetic improvement of Stevia needs to be investigated to increase its productivity. Although this plant has a narrow genetic diversity, genetic improvement through polyploidization may succeed. Meanwhile, genotypic characters of tetraploid Stevia were previously reported. This study then observed the phenotypic characters of the tetraploid plants, which aimed to evaluate the morphological and anatomical characteristics of tetraploid Stevia clones compared to its wild-type parental diploid plant. Three tetraploids and one diploid clone were grown in the field for 12 weeks. The results of qualitative descriptive characters showed that the tetraploid clones B60.3H8, P1T22 and P3T5 had habitus type, shoot bud shape, leaf margin, leaf venation, shape, and type of stem, type of flower, and seed similar to the diploid parental clone. However, the quantitative characters showed that the tetraploid clones had leaf size, stem diameter, root size, length of the single flower, length of the flower stalk, and length of fruit which were more extensive than those of the parental diploid clone. The leaf color of tetraploids was a darker green, and the range of initial flowering times was earlier. This finding gives more understanding of the phenotypic and anatomical characteristics of Stevia tetraploids compared to their parental diploid plant.

Abstract

Eastern little tuna (Euthynnus affinis) is a commercially important species for coastal communities in the western and southern part of Indonesia. However, little is known about its characteristics. Therefore, a comprehensive and broader research of its population structure is imminent in response to conserve and manage the fishery sustainably. This study aimed to fill the gap of the lacking information on the stock separation of eastern little tuna within the Indonesian archipelagic waters and its Economic Exclusive Zone (EEZ). Population genetic approaches were used to examine population structure using the mitochondrial DNA (mtDNA) control region marker. A total of 94 samples were collected from nine landing sites between January to September 2020. Polymerase chain reaction (PCR) was used to amplify the samples, and Sanger sequencing was used to sequence them. The findings showed a mean value of 0.922 for genetic diversity (Hd) and 0.009 for nucleotide diversity (π). Both of these numbers pointed to a high level of genetic diversity. A further population analyses using Analysis of Molecular Variance (AMOVA) and Discriminant Analysis of Principal Component (DAPC) confirmed a mixing gene pool with no distinct population structure detected (ΦST value of 0.097 and p-value>0.05).

Abstract

Latex diagnosis is widely adopted in natural rubber-producing countries to optimize the natural rubber production through a physiological-based latex-harvesting system management. This study is the first bibliographical searching and meta-analysis on the variation of latex physiological parameters i.e. sucrose, inorganic phosphorus, thiols, and total solid content. The study used information extracted from 158 scientific papers. Descriptive statistics, agglomerative hierarchical clustering, and principal component analysis were performed to characterize applications of latex diagnosis, how often parameters are used and interpreted as well as the variation of its parameter values. From 158 papers, latex diagnosis parameters were used in 114 agronomy, 22 in physiology, and 22 in breeding papers. The agglomerative hierarchical clustering analysis indicated that sucrose and inorganic phosphorus contents were clustered together and total solid and thiols contents were located in another cluster. The average values of the total solid content, sucrose, inorganic phosphorus and thiols were 43.9%, 9.4 mM, 16.5 mM, and 0.52 mM, respectively. The percentage of interpretation is 63.3% for sucrose, 54.4% for inorganic phosphorus, 47.5% for thiols, and 41.1% for the total solid content. The low interpretation of thiols and total solid contents question their relevance in latex diagnosis. The low adoption of latex diagnosis in breeding could hinder the selection of activities leads to a limitation of selection for long-term high yielding and stress-adapted clones.

Abstract

Massive tubule fibrosis is a histopathology hallmark of chronic renal failure (CRF). The previous study of protein hydrolysate of green pea (Pisum sativum) bromelain (PHGPB) showed promising results as an antifibrosis in glucose-induced renal mesangial culture cells, by decreasing their TGF-β levels. In this experiment the anti-inflammatory, anti-fibrotic effect of PHGPB in Cisplatin-induced chronic renal failure (CRF) rats was measured. The purpose of this study is to evaluate the anti-inflammatory and antifibrosis effect of PHGPB in Cisplatin-induced chronic renal failure rats. Five groups consisted of five rats: negative control, Cisplatin control, and three groups of Cisplatin+PHGPB (dose of 100, 200, and 400 mg/kg BW/day) treated for 56 days. The examined parameters are Beta-2-microglobulin (β2MG), hs-CRP, histopathological observations of Masson's trichrome stain, and IHC. The level of β2MG and hs-CRP in the Cisplatin+PHGPB group lowered and was highly different from Cisplatin control (p<0.05) depending on doses. In histopathology, the Cisplatin+PHGPB 400 mg/kg BW group showed less fibrosis and no significant difference with the negative control in Masson trichome staining. While in IHC histopathology, PHGPB treatment slightly ameliorated TGF-β expression and intensity of TGF-β values convincingly. In conclusion, PHGPB can relieve kidney fibrosis in cisplatin-induced nephrotoxicity rats: Emphasis on anti-inflammatory activities.

Abstract

Tinjil Island was established as a Natural Habitat Breeding Facility for long-tailed macaques (Macaca fascicularis) in 1997. Between February 1998 and January 2007, 603 (61 males and 542 females) simian retrovirus (SRV) free long-tailed macaques were introduced to the island on the south coast of West Java and function as a primate resource and conservation program. To date, 3256 progenies have been harvested and used as the animal model. Therefore, it is necessary to survey the current population of the long-tailed macaques to evaluate whether the population is still under the island’s carrying capacity. This research aims to identify the population estimate of long-tailed macaques currently occupying the island. The observation was conducted in July 2021 using line transect sampling starting from 07.00 AM and 01.00 PM. Twelve observations were conducted during the study using CD and ES transects. CD (Chuck Darsono) and ES (Emil Salim) are the two longest trails on the island and represent the names of the people who initiated the captive breeding of Tinjil Island. The estimated group density of the long-tailed macaques on Tinjil Island is 13.46 groups/km2, while the estimated population density is 111.04 individuals/km2. The population estimated on the island is 627.38±23.53 individuals. The number indicates that the population is still under carrying capacity.

Abstract

The nutritional content of mushrooms depends on the type of substrate in the growing medium. Lignocellulose is one of the substrates used for fungal growth media. In this study, the effect of adding dried reeds (Imperata cylindrical (L.) Beauv) on Sengon (Paraserianthes falcataria (L.) Nielsen) sawdust-based media was investigated for wood ear mushroom (Auricularia auricula-Judae) fruiting body. Reeds have been added to Sengon sawdust as wood ear mushroom cultivated medium with variations of S0, S1, S2, S3, and S4 (0%, 25%, 50%, 75%, and 100% of reeds, respectively). S0 was designed as the negative control and S4 as the positive control. The evaluation was carried out against the C/N ratio, yield, biological efficiency (BE), nutritional content, and antioxidant activity of fruiting body mushrooms after 10, 20, and 30 days planted. The highest C/N ratio and BE were obtained from the S1 medium. The lowest moisture content was obtained from the S0 medium. The lowest fat content was obtained from the S4 medium. The best result of nutritional analysis includes the following; the highest total carbohydrate, ash, crude fiber, and crude protein content was obtained from S3, S4, S3, and S0. Furthermore, the best result of antioxidant activity against ABTS and DPPH was obtained at methanol extract of fruiting body mushrooms from S1 medium, compared with ascorbic acid as the positive control. This study has shown that adding reeds to the cultivated medium influences the growth, nutritional content, and antioxidant activity of wood ear mushrooms.

Abstract

Pyrolysis gas chromatography-mass spectrometry (Py-GCMS) is a simple, rapid, and reliable analytical technique to assay lignocellulose biomass. This study aims to analyze the chemical content of various ages of platinum fast-grown teak wood using PyGCMS coupled with interdependence multivariate analysis. Fifty-eight peaks were shown in the pyrogram originating from carbohydrates, lignin, and extractive derivatives. Along with age, platinum fast-grown teak wood showed higher carbohydrate derivatives in heartwood than sapwood. Compared to teak wood grown in conventional (between 36.72-45.69%), platinum fast-grown teak wood has a higher content of carbohydrates (42.82-48.04%). A substantial amount of G-unit lignin was detected in the sapwood, while the S-unit lignin dominated the heartwood. The extractive content of 10-years-old teak wood heartwood was 4.82%, higher than 10- and 20-years-old heartwood from conventional wood (2.23% and 8.88%, respectively). Multivariate analysis of the chemical compound showed that Py-GCMS could be utilized to classify platinum fast-grown and conventional teak wood. 2-methyl anthraquinone (MAQ) content of 10-year-old fast-grown teak wood was 2.5 times higher than 20-year-old conventional teak wood. Based on the study, platinum fast-grown teak wood is promising as alternative wood material to fulfill the market demand for conventional teak wood.

Abstract

Red amaranth (Amaranthus cruentus L.) is a fast-growing and nutritious leafy vegetable. The seed population density needs to be known appropriately to obtain the optimal yield of marketable sizes plants. The residue of black soldier fly (BSF) larvae culture has been recognized as a potential source of nutrients for cultivating red spinach plants. This study was designed to search for the best combination of plant population density and BSF concentration to obtain the optimal marketable yield of the red amaranth plant. In addition, an accurate leaf area estimation of the red amaranth plant was also developed using leaf dimensions as a predictor with several regression models. Two experiments were conducted. Firstly, the BSF residue was applied at a high rate (up to 50%) using a floating culture system. Application of the residue at the rate of 30% and higher significantly inhibited the growth of the red amaranth. Secondly, the application rate was reduced to 10% and 20%, and the experiment was conducted using the conventional cultivation system. Results indicated that the optimum application rate of the BSF residue was 10% for enhancing growth. Application of seed density at 30 mg/dm2 produced an optimum marketable yield of the red amaranth since a higher population density causes plant-plant competition. Thus, creating high size variability within the population or reducing the average size of the harvested plants. Lastly, the leaf area of red amaranth can be accurately estimated using the leaf length x width (LW) as a predictor using the zero-intercept linear regression model.

Abstract

Distribution of freshwater sponges (Porifera: Spongillida) in Indonesia is currently insufficiently reported and underestimated compared to marine sponges. An inventory study on freshwater sponges in East Java after Indonesian independence in 1945 is yet to be carried out. For this reason, we reported new records of two freshwater species, Eunapius carteri (Bowerbank, 1863) and Oncosclera asiatica (Manconi and Ruengsawang, 2012) in Porong river, East Java, Indonesia. E. carteri species was originally described in Mumbai, India and its presence in Java was reported in 1927, 1928, and 1930. DNA barcoding and molecular phylogenetic analysis using mitochondrial COI was able to successfully identify our specimens as E. carteri, while analysis using the nuclear ITS markers placed our samples with other Eunapius species. Furthermore, in this study we report for the first time in East Java, Indonesia, the presence of O. asiatica. The O. asiatica species was originally described from Pong River located in Lower Mekong, Thailand. We concluded our specimens to be O. asiatica based on the morphology, skeleton, and spicule composition of the specimens that were similar to the samples recorded in Thailand. We were only successful in obtaining the COI sequence of O. asiatica. Furthermore, our samples did not group to the publicly available sequence of its congener, namely Oncosclera sp. Therefore, further molecular taxonomy and morphological analysis is needed to explore the diversity of freshwater sponges in general and to conduct species delimitation of E. carteri and O. asiatica in Java, Indonesia, and Asia

Abstract

Rice cultivation as intercropping in plantations is a potential approach to increase land resource efficiency. Implementation of rice intercropping would require genotypes adapted to shaded environments. This study aimed to clarify the interaction of genotype and environment on agronomic characteristics of upland rice grown under intercropping system and to identify suitable genotypes for this particular cropping system. Multi-location trials evaluated twelve upland rice lines and two check varieties in eight upland sites during the wet season (WS) 2015-2016. Rice was grown as intercropping in six sites and as monoculture in two sites. Rice as intercrop was cultivated in between plantations of tall coconut, rambutan, teak, albizia, and natural rubber. The result of this study revealed that the interaction between genotype and environment was significant for all agronomic characteristics. The genotype B12056F-TB-1-29-1 was the best performer when grown as intercropping in Subang and Indramayu, with shading intensities of 65% and 44%, respectively. The genotype B11908F-TB-3-WN-1 was the best yielder in Cianjur and Lampung Tengah, which had 37% and 54% shading intensity, respectively. The genotype B12825E-TB-2-4 was the best performer in Lampung Timur with shading intensity of 45%, while Jatiluhur was the best genotype in Banyumas with shading intensity of 82%. The yield of rice genotypes grown as monocultures was higher than as intercropping. Among the genotypes, B12056F-TB-1-29-1 showed the highest yield across sites. Stable and high-yield genotypes identified from this study are expected to be adopted by farmers for intercropping rice cultivation.
