Abstract

Dendrobium capra is an endemic orchid species on the island of Java, Indonesia, which blooms only once a year, usually in February. In the flowering process, LEAFY (LFY) gene and its homologs are considered as key regulators in flowering of higher plants, including orchids. To understand floral regulatory mechanisms in orchids, information on the flowering gene structure needs to be explored. Partial sequences of LFY homologue of D. capra has been isolated and consists of 220 bp encoding 72 amino acid sequences. Bioinformatic analysis using Blastp search showed high similarity between the LFY genes of D. capra with other orchid LFY genes and has adjacent evolutionary relationship among orchid’sLFY. Amino acid sequence alignment result showed similar characteristic with other orchid’s LFY with conserved motif leucine-rich repeat and DDPRRRLLLLSPDQHN amino acid motif.

Abstract

Abdopus aculeatus has good camouflage capabilities in nature. The objective of this study is to obtain information on the camouflage behavior of Abdopus aculeatus in nature (in situ). We used an explorative description to observe the camouflage behavior of 24 octopus samples at a number of points on the Panjang Island, Buton Regency. Abdopus aculeatus was identified molecularly using a mtDNA COI blast to determine the target species of observation. Any of the camouflage behavior found was documented and analyzed descriptively. Generally, there are four forms of observations for camouflage behavior; matching body color to wide array of natural background, immersing itself in the sand, resembling a specific object, and being part of the objects surrounding. The various camouflages patterns obtained show a process of defense evolution in minimizing the detection of predators or octopus prey.

Abstract

Isolation of soil fungi was done to find an enviromental friendly dyes for dyeing cloth. The aims of this study include isolation and identification of soil fungi from burning waste, cassava rhizosphere, and compost in Cibinong Science Center Area; and evaluation of dyes potential produced by the soil fungi in combination with alum and copper sulphate mordants. Thirty-six isolates of the soil fungi were successfully isolated from the burning waste, cassava rhizosphere, and compost. These include Aspergillus, Colletotrichum, Emericella, Eurotium, Fusarium, Mucor, Paecilomyces, Penicillium, Rhizopus, and Trichoderma. The soil fungi were dominated by asexual morph (77.78%) of which Aspergillus (3 species and 15 isolates) was found as the most common genus from the three samples. A total of 14 isolates were found potential as dye-producing fungi. These include Aspergil-lus sp. strain R-2 (1 isolate), A. fumigatus (3 isolates), Penicillium sp. strain GRC-1 (5 isolates), Penicillium sp. strain R-3 (1 isolate), Penicillium sp. strain RC-1 (3 isolates), Trichoderma harzianum (1 isolate); and Monascus purpureus (1 isolate; as control). Color intensity produced by fungal dyes in combination with alum and copper sulphate as pre-mordanting agents is higher than alum and copper sulphate as post-mordanting agents.

Abstract

Alanine is a secondary metabolic secretion from Mirabilis jalapa. It is used as a modulation of natural pesticide compound. Alanine is predicted to act as an inhibitor compound in the defense mechanisms in the insect body. This study investigated the modeling structures and the protein receptor from alanine in the immune system mechanism and their optimization of the effectiveness as biopesticides to the insects. This research was conducted using an in silico modeling through the reverse docking stage, including the collection of 3D structures of natural compounds, prediction of target protein, receptor profiling, clarification of the potential of alanine compounds based on mode of action with PyRx 0.8 software, and interaction visualization between alanine compounds with the target protein using PyMOL and LigPlus+ software. The results showed that the alanine compounds from M. jalapa plants have targeted well the glutamate receptors in the insects. Both alanine and glutamate compounds have the same interactions with the glutamate proteins receptor shown by the Van der Waals interaction, e.g. the hydrogen bonding on certain amino acids has binding affinity of -15.889 kJ/mol. The interaction between alanine and glutamate affects the signal transduction cascade at the cellular level due to a neuromuscle and olfactory inhibitor. In addition, the continuous interruption of signal transduction affects the dysfunctional immune system of the insect body leading to their mortality.

Abstract

The objective of this study is to establish the effect of inoculum concentration and incubation time of protease activity on pigeon pea beans fermented by Aspergillus niger. The study comprises two independent variables: the inoculum concentration of Aspergillus niger, which consists of four levels (0 mL/g; 0.2 mL/g; 0.4 mL/g, and 0.6 mL/g), and six levels of incubation time (0 h, 24 h, 48 h, 72 h, 96 h, and 120 h). The obtained data were tested using two-way analysis of variance (ANOVA) followed by an LSD test with a significance level of 5%. The results show that the inoculum concentration of Aspergillus niger and incubation time do affect the activity of the protease enzyme. The highest enzyme activity of 0.298 U/ml was obtained at an inoculum concentration of Aspergillus niger of 0.4 mL/g, with an incubation time of 96 h (P2K4).

Abstract

Ultrafine particles have been attached the attention for researchers due to their impacts on human health. Ultrafine particles can be emitted fromburning process, such as forest burning, agriculture waste burning, cigarette, etc. In this study, ultrafine particles produced by cigarette smokes hasbeen investigated as a function of smoking rate. The samples consisted of different types of Indonesia cigarette called Kretek cigarette. Thequantification of emission factors was conducted by the burning of the cigarette samples, then the smoke that was sucked with a different flow rateusing an adjustable pump. The flow rate was chosen to correspond as close as the variation of the rate that people smoke. The measurements ofultrafine concentrations were carried out using an ultrafine particle counter P-Trak TSI 8525 capable of measuring particles with the diameter in therange of 20 to 1000 nm. The results showed that the emission factor of ultrafine particles significantly depended on the smoking rate. A highersmoking rate produced higher average ultrafine particle emission factor.

Abstract

Gewang (Corypha utan Lam.), a palm species, is utilized by villagers as a source of starch in East Nusa Tenggara for daily needs. This study was to describe how local people in Nusa Tenggara produce and utilize gewang starch for their diet, particularly as a rice substitute. The starch is extracted from its trunk and consumed after being cooked with grated coconut. This dish, known as “akarbilan” or “puta’ laka”, becomes the most common food in that area during transition period. Based on our analyses, the nutrition properties of 100 gr gewang starch is composed by water 11.995%, ash 0.518%, fat 0.20%, protein 0.69%, carbohydrate 86.59%, amylose 32.726%, amylopectin 51.11%, glucomannan 12.27%, Calcium (Ca) 100.52 mg, Phosphorus (P) 136.74 mg, Iron (Fe) 3.390 mg, and Vitamin B1 0.108 mg. The results suggested that the nutrition properties of gewang starch almost similar with the sago starch. However, gewang has more prospective potency for food alternative, especially in dry land such as Timor island and adjacent regions in order to build food security in Indonesia.

Abstract

Zanthoxylum avicennae (Lam.) DC. [Karangean] is a widely distributed plant in Southeast Asia and has potential in the pharmaceutical and food flavour industry with fruits and leaves rich in essential oils. The plant materials of Z. avicennae (Lam.) DC. [Karangean] were a plant collection at Bali Botanical Garden which collected from West Nusa Tenggara, on June 15th 1993. The essential oils were extracted by hydrodistillation from fresh fruits and leaves of Z. avicennae and the phytochemical composition were analysed by Gas Chromatography-Mass Spectrometry (GC-MS). The yields of essential oils were 2.75% from fruit oil and 1% from leaf oil. Respectively, a total of 41 compounds were identified from the fruit oil and 11 compounds from the leaf oil representing 91.1% and 99.81% of the total oils composition. The major compounds of the fruit oil were 1.8-cineol (12.34%), 1-para-menthen-8-yl acetate (6.24%), l-Limonene (6.09%), Cyclopropane (5.06%), Hexane (3.84%), 3-Methyl-2-(2-methyl-2-butenyl)-furan (3,74%) and predominant compouns of the leaf oil were Estragol (87.13%), 1.8-cineol (4.28%), Trans-Anethole (3.51%), Myrtenyl Acetate (0.65%), isopiperitenone (0.62%). The highest contents of these essential oils were monoterpene and sesquiterpene and these componentshad desirable properties for use in industrial companies. Therefore, the essential oils of Z. avicennae [Karangean] from West Nusa Tenggara contained chemical compositions which had potential to be developed for various human needs.
