Abstract

In general, community forest management is still limited to the management of individual farmers so that it affects diversity, especially in the form of stands. This study aimed to explore the stand structure and composition characteristics and develop a model for estimating the potential stand volume at the Citragaluh community forest management unit with 55 observation plots based on a combination of slope and density classes. The data taken includes slope; plant species; plant coordinates; planting pattern and spacing; tree diameter, tree height, and canopy density. The results of plot observations showed that the cropping pattern of Citragaluh Community Forest Management Unit (CFMU) consisted of monoculture (10.9%), mixed stands (20%), agroforestry (29%), dry fields (27.27%), wet fields (9%), bamboo stands (1.8%) and built-up area (1.8%). The trees species found were Jeungjing, Mahogany, Teak, Tisuk, Sobsi, Akasia, and Puspa. Based on the results of stratification, diameter distribution, and stand volume, mixed gardens were the best cropping pattern. This research proves the role of community forest as a transition between plantation forest and natural forest based on the stand form and composition. The stand volume potential estimator model chosen was linear with the equation Y = 0.074X1 + 2.924 X2 - 1.679 where X1 = slope and X2 = Normalized Difference Vegetation Index (NDVI). The values of R2 models are 51.3%. The average potential for the Citragaluh is 119,835 m3/ha, which tends to be higher than other community forest studies.

Abstract

Stevia rebaudiana leaves can be used as a sweetener alternatives because they contain steviol glycoside derivative compounds, including steviosides and rebaudioside-A. Propagation of Stevia is more optimally carried out using in vitro culture when compared to conventional propagation through seeds or cuttings. This study aimed to evaluate the formation and growth of Stevia shoots and leaves in MS medium containing a mixture of IAA and BAP with MS medium containing kinetin only, as well as evaluating the use of a liquid medium containing kinetin. Stevia was initiated from apical shoot then grown in MS medium containing a mixture of IAA and BAP with MS medium containing kinetin only. Stevia was subcultured every 4 weeks. Several parameters measured were number of axillary shoots and number of leaves. It was transferred into a liquid medium for 7 days. The results showed that the formation and growth of axillary buds and leaves at the initiation stage were better in medium containing IAA and BAP compared to medium containing single hormone kinetin. At the stage of shoot multiplication and maintenance, cultivation in semi-solid medium containing kinetin showed more leaves and axillary shoots compared to that cultivated in semi-solid medium with the addition of IAA and BAP. Plants acclimatized in liquid medium supplemented with 1 ppm kinetin showed fast plant growth but were not accompanied by sturdy stem growth. The presence of brownish color on certain parts of the plant such as in some leaves and stems was also observed.

Abstract

It has been recognized in many studies that wildlife tourism practices might generate a negative impact on wildlife, particularly during the reproductive period. Some wildlife may lower their sensitivity towards tourist presence, for instance in Komodo. Understanding to what extenthabituation occurs in Komodo would be necessary for tourism management in Komodo National Park (KNP). Therefore, this study aimed to identify the response of Komodo to tourist presence during mating and nesting activities. The observation was conducted in Loh Buaya, which is one of the tourism sites in KNP. Komodo’s responses were divided into (1) avoidance; (2) neutral; and (3) aggressive under categorized stimulus: tourist number (i.e., < 5 persons; 5-10 persons; and > 10 persons) and distance (i.e., < 5 m; 5-10 m; and > 10 m). Correlation analysis was performed to identify any influences on mating and nesting activities. Our results revealed that Komodo inhabiting tourism facilities havebeen habituated to tourist presence. Different tourist frequencies did not influence Komodo mating activities (r(20)= 0.036, p=0.873), the nest preparing activity (i.e., digging proportion; r(22)= 0.054, p=0.803) and the guarding activity (i.e., nesting proportion; r(22)= 0.314, p=0.135).Nevertheless, our results indicated possible impacts due to tourism activities and its supporting facilities, such as dominated mating pairs, threats to female reproductive success, and human-Komodo conflicts. Therefore, habituation evi- dence must be carefully considered in order todevelop more corresponding strategies and achieve sustainable tourism practices.

Abstract

Glutathione Reductase (GR) belongs to the NADPH-dependent flavoprotein oxidoreductase family and is found in both prokaryotes and eukaryotes. The GR gene is considered to play a key role in the elimination of oxidative reaction products by looking at the level of gene expression of GR rice in dealing with  drought stress using qPCR. One of the important steps to develop a specific, effective and efficient qPCR is the primer design. Several studies analyzing GR gene expression in rice have also designed primers. However, the primer still lacks an ideal characteristic of primer, as it still has a secondary structure. This studies aims to design rice GR specific primers and optimize the annealing temperature for GR gene expression analysis on rice. Primers were designed using the  Primer3 and Geneious Prime and checked for specificity using the Primer-BLAST tool. The selected primer pairs were then optimized for annealing  temperature using gradient PCR. The best primer design results were GR-Forward 5’-ACGATTGCAGCCAGTGAAGA-3’ and GR-Reverse 5’-TGCGGCAATACTATCAACATCC-3’, with an amplicon length of 204 bp, primer base lengths of 20 and 22 nucleotides, Tm values of 60°C and 58.9°C, %GC of 50% and 45.5%, respectively. This primer pair had no secondary structure, both hairpin and self dimer. Gradient PCR showed the optimum annealing temperature for this primer pair was 52.2oC so that the primer can be used as a specific primer to analyze  the GR gene expression in rice using qPCR.

Abstract

Asteraceae is known as the largest family of flowering plants. Despite some species members being invasive plants, these species are often adopted and utilized by local community groups for food, traditional medicine, and other uses. In our ethnobotanical study of Asteraceae, we identified ways a local Sundanese community group in West Java utilizes a diverse range of species in the family for different purposes. Our study focuses on a Sundanese village called Cihanjawar, located in the regency of Purwakarta, using ethnobotany and ethnomedicine approaches. People of Cihanjawar utilize some species of Asteraceae for food as ‘lalapan’ and traditional medicinal purposes. In-depth, semi-structured interviews with the people of Cihanjawar were conducted to collect primary data regarding the utilization of Asteraceae species as food and traditional medicine. A total of eight species of Asteraceae were found during the field-guided exploration in Cihanjawar Village, which include Acmella paniculata, Ageratum conyzoides, Calyptocarpus vialis, Crassocephalum crepidioides, Dichrocepala integrifolia, Emilia sonchifolia, Erechtites valerianifolia, Sphagneticola trilobata, some of which are considered invasive alien species. The species of A. paniculata, C. crepidioides, E. sonchifolia, Er. valerianifolia is eaten as a raw food (lalapan, Ind.). Then Ag. Conyzoides and C. crepidioides are utilized in traditional medicine. C. vialis, D. integrifolia, and Sphagneticola trilobata are not used by the people of Cihanjawar as food or as traditional medicine.
