Abstract

Traditionally, the genus Philautus Gistel, 1848 contains small Rhacoporid frogs that lack vomerine teeth and a direct development tadpole stage. In Java, this genus consists of 3 species, including Philautus aurifasciatus, Philautus jacobsoni, and Philautus pallidipes. It is known that Philautus aurifasciatus and Philautus jacobsoni are sympatric species from Mount Ungaran and are morphologically difficult to distinguish. Therefore, information is needed through the phenetic characters of each population in the area to identify differences in their morphology. This study aimed to analyze the morphological characteristics of  Bush Frog Philautus spp. on Mount Ungaran in terms of meristic character through a direct field survey and comparison methods. Furthermore, it was conducted by observing 32 specimens of Philautus spp. from Mount Ungaran and compared with the Philautus aurifasciatus from Mount Gede Pangrango with 18 meristic characters. The results showed that Philautus spp. is similar to Philautus aurifasciatus in terms of their meristic characters. The results of the meristic analysis showed that Philautus spp. has a variety of dorsal colors from brown, purple, green, and gray with two types of patterns including patterned groups (resembling letters H, X, and V) and abstract. Furthermore, the throat, stomach, and lower thighs are granular with three snout shapes (protruding, round, and sloping). It has a loreal oblique tympanum and canthus rostralis. The forelimbs are not webbed while the hindlimbs are half webbed, and the inner metatarsal is an elongated oval in shape. Meristic analysis provides a basis for strengthening the taxonomic status of Philautus spp on Mount Ungaran, as well as information the distribution in Mount Ungaran.

Abstract

Moringa (Moringa oleifera Lam.) is a cultivated plant that reported have many benefits. Indonesian people have utilized moringa as a vegetable widely but it is never used as functional food. The distribution data of moringa in Indonesia is needed to develop moringa as an additional nutrient for functional food. The aim of the research was to draw up the distribution map of moringa in Java and Lesser Sunda Islands (LSI). In addition, this distribution map was also attributed with average annual rainfall to know the preference of moringa to life depend on the rainfall. This research has been conducted with four approaches: collecting specimens, direct observation of living plant, direct observation of specimen herbarium and literature study. All data were analyzed and arranged into the distribution maps of moringa in Java and the LSI attributed with annual rainfall. The result showed that moringa in entire Java mostly distributed in the area of Jakarta, West Java, Central Java, Yogyakarta, the north part of East Java, Madura and Kangean. While, moringa in LSI distributed in the southern part of Bali, Lombok, Sumbawa, Kupang, Flores, Sumba and Alor. The average annual rainfall of 1500-2000 mm is the most ideal condition for moringa plants to grow well. This map and information can be utilized by the stakeholders to determine the most appropriate place for moringa cultivation and their development as as a functional food.

Abstract

Phylogenetic or population genetic studies have been focused on finding genetic variations in mitochondrial DNA (mtDNA) because mutations in this region contained five times higher than other genetic materials. The aim of this research was to generate PCR-RFLP D-loop mtDNA profiles of some Indonesian domestic waterfowl. The samples were 35 local ducks, 5 muscovy duck, and 5 geese. These local ducks included on seven types of Javanese ducks in Central Java, i.e. Magelang duck, Peking duck, Pengging duck, Tegal Branjangan duck, Tegal Jarakan duck, Tegal Blorong duck, and Tegal Lemahan duck. PCR technique was used to amplify the D-loop genes, and RFLP analysis of the D-loop was performed with AluIand RsaI. The results show that muscovy duck has no restriction sites in D-loop gene. Moreover, goose has a restriction site of AluI in D-loop gene at 550 bp and 187 bp; and it has no restriction site of RsaI. The analysis of RsaI-RFLP in mtDNA D-loop region of ducks resulted in 1 restriction fragment pattern which can be applied in the identification of duck to differentiate it from goose and muscovy duck. PCR-RFLP analysis duck D-loop mtDNA using AluI and RsaI restriction enzyme resulted in 3 combinations of restriction fragment pattern shown in 3 haplotypes (A, B, and C). Genetic diversity of Indonesian domestic waterfowl population could be identified by using PCR-RFLP analysis on mtDNA D-loop region. So far, there are few results of research on Indonesian domestic waterfowl genetic characteristics based on PCR-RFLP mtDNA D-loop marker. Also, this research has a good contribution on genetic characterization of local duck. The characterization is an important aspect to maintain breed quality and manage the genetic resources of Indonesian germplasm and in facilitating the breeding program.

Abstract

Spirulina platensis is a phytoplankton, the cell wall composed of complex sugars so easily digested by fish. The present study was carried out to investigate stimulation cycle of feed deprivation with feed supplemented S. platensis the best to increase growth, hematological and body composition of gurami (Osphronemus gouramy). Groups of 24 fish, each in triplicate, were exposed to four different treatment for a period of 56 days. Sample measurements of growth done every 14 days, hematological and body composition measurements carried out at the end of the experiment. Growth was significantly different between stimulation cycle of feed deprivation and the control (P0.05). Conclusions result showed that stimulation cycles of feed deprivation could not improve growth and hematological, but could improve body composition. Feed deprivation is done to reduce the cost of production, high production costs due to high feed prices. During research on feed deprivation is done by giving commercial feed, this study is to provide feed supplementation S. platensis. Thus, the results of this study can be useful for science as S. platensis information can be used as a food supplement and and for the people cultivating gurami should be fed daily supplementation of S. platensis.How to CiteSimanjuntak, S.

Abstract

Carica pubescens Lenne K. Koch, an endemic species in Dieng mountains, must be conserved. The in vitro conservation has been developed, but sub-culture period needs to be extended. This study aimed to obtain a more efficient in vitro conservation protocol of C. pubescens. The research was carried out experimentally by using a completely randomized factorial design with three factors, namely decreasing in storage medium concentration (75% and 50% of MS medium), temperature (4oC and 8°C), and irradiation duration (8 hours/day and 16 hours/day). Shoots were kept in the storage medium for 6, 9 and 12 months, then their viability were tested by growing them in the regeneration medium. Data were analyzed by Analyses of Variance and Least Significant Difference Test. The results showed that medium concentration of 50% of MS, the temperature of 8 °C, and 16 hours/day of irradiation were able to suppress the C. pubescens growth in vitro storage for six months and could maintain its viability in the regeneration medium. Based on these results the medium concentration of 50% of MS, the temperature of 8 °C and 16 hours/day irradiation can be used for in vitro conservation of C. pubescens without sub-culture for six months.

Abstract

Rennet, a milk coagulant exhibiting proteolytic activity, is a crucial component in cheese industries. Its price and availability have discouraged the growth of some small scale cheese industries. Therefore, an alternative for rennet will be beneficial for the industries. Among other sources, plant proteases offer some advantages as rennet alternatives. This study aimed to investigate the potential of plant proteases obtained from the latex as potential rennet alternatives. A total of six plants from the genus Ficus and Artocarpus were screened for their proteolytic activity and milk coagulating ability. The screening indicated that all six tested plants displayed proteolytic activity at various levels, but only Ficus benjamina and Artocarpus heterophyllus produced a firm milk curd. Hence, both F. benjamina and A. heterophyllus were determined to be the most potential. Further characterizations suggested that F. benjamina and A. heterophyllus protease were optimum at pH 7.0 also at 50°C and 40°C, respectively. At their optimum conditions, both proteases exhibited a lower MCA/PA ratio than that of the rennet. This study contributed to scientific knowledge development by becoming the first to characterize the optimum conditions of F. benjamina and A. heterophyllus’ proteases, investigate their MCA/PA ratio, and compare their activity against commercial rennet. The examination of their potentials as rennet alternatives could benefit small cheese industries and the communities.

Abstract

Antiobesity medication is available as therapeutic compounds that can reduce fat digestion by the inhibition of pancreatic lipase. Actinobacteria have the potency as source of bioactive compounds with various biological function including as pancreatic lipase inhibitor.  However, the potency of endophytic actinobacteria from Rhododendron spp. as source of pancreatic lipase inhibitor producer has not been reported yet. The aim of this study was to examine the potential of pancreatic lipase inhibitory activity of 23 endophytic actinobacteria from Rhododendron spp.; to characterize their colony based on morphology and molecular analysis. Screening test of pancreatic lipase inhibitor was conducted using the supernatant of endophytic actinobacteria, lipase pancreatic porcine (L3126) and p-nitrophenyl butyrate. The supernatant of selected isolates was extracted using ethyl acetate. The result showed that various inhibitory activities ranging between 0.00 until 91.69%. There were 11 out of 23 isolates that have potential as pancreatic inhibitor. Amongst them, the extract of four selected isolates, i.e. RZP 1.3, RSSB 3.2, RSS 2.1, and RJB F3.2 demonstrated inhibitory percentage of more than 80%. The RJB F3.2 extract showed to have IC50 value by 431.48 µg mL-1 compared to control, i.e. Xenical (89.07 µg mL-1). Phytochemical analysis exhibited that the extract of the selected isolates contained alkaloid which may function as pancreatic lipase inhibitor. Based on the morphological character, the selected isolates have various morphological colonies and 16S rRNA gene sequence revealed the sequence homology to Streptomyces spp. The data clearly indicate that endophytic actinobacteria from Rhododendron spp. have potency as pancreatic lipase inhibitor producer and further studies could be explored for the development of antiobesity agent.

Abstract

Xylocarpus granatum is mangrove plant that traditionally used as face powder in Central Sulawesi, Indonesia which related to antioxidant, antiglycation and tyrosinase inhibition activities. This study aimed to evaluate the potency of X. granatum as a tyrosinase inhibitor, antiglycation, and antioxidant. The leaves, stem, stem bark, fruit flesh, fruit peel, and kernel of X. granatum were extracted using ethanol then their tyrosinase inhibition, antiglycation, and antioxidant were evaluated. Tyrosinase inhibition activity was evaluated using in vitro assay with L-tyrosine and L-DOPA as the substrate of monophenolase and diphenolase. Antiglycation activity was studied by measuring the excitation and emission fluorescence from glucose and fructose reaction with Bovine Serum Albumin. Antioxidant activity was measured using the DPPH radical scavenging assay. The result showed that the ethanolic extract of fruit flesh has higher potency as tyrosinase inhibitor (IC50 of 393.8 mg/L and IC50 of 448 mg/L, respectively for monophenolase and diphenolase). Antiglycation assay showed that the ethanolic extract of stem bark provides the strongest antiglycation activity with an IC50 of 118.1 mg/L. Meanwhile, fruit peel provides the strongest antioxidant activity with an IC50 of 5.5 mg/L. Fractionation of ethanolic extracts of each part of X. granatum tree yield fractions with lower bioactivity compared to the crude extract. Moreover, stem extract and fractions from two different locations (Tarakan and Kendari) tend to have different bioactivities strengths.  The stem part of X granatum could be developed as new raw material of cosmetic product in Indonesia, while ethanol as the solvent for extraction, and the different bioactivity of stem extract from different location can be the consideration for the industry to standardize the extract prior to production of final product.
