Abstract

For a long time, people in West Java, Indonesia have used Selaginella as a traditional cure for several ailments including fever, minor wounds, broken bones, women’s health disorders or postnatal bleeding. However, information on the active compounds of the plant from Java Island has not been fully expounded. The objective of the research was to reveal the diversity of bioactive compounds and amentoflavone content of Selaginella from Java Island in order to optimize the use of this plant as a medicinal plant. Selaginella plants collected from 29 locations in Java were extracted and subjected to colorimetric and thin layer chromatography test to qualitatively analyze the bioactive compounds of alkaloid, phenol, and steroid. In addition, high performance liquid chromatography was performed to analyze the amentofalvone content of Selaginella extract. The research result showed that all the examined Selaginella species contained alkaloid, flavonoid, saponin, tannin, and steroid, but they did not contain hydroquinone. Seven of them contained the biflavonoid type of amentoflavone. The highest amentoflavone concentration, 6.87 ppm, was found in S. subalpina that originated from Gedung Songo, Central Java. Those results indicated that more than one Selaginella species originating from Java Island had marked potential for use as medicinal plants.

Abstract

Speaking is one of the most difficult skills in language learning particularly in learning English as a foreign language. The purpose of this qualitative study was to explore the issues of speaking anxiety, the factors influencing their speaking anxiety, and the strategies they employed to alleviate the anxiety at one English teacher education program in Jambi, Indonesia. In order to collect the data, a semi-structured interview was employed and guided by an interview protocol to stimulate the participants in answering the questions during the interview. Due to the Covid-19 pandemic, we only had access to invite 12 students to participate in our study-they were nine male and three female student teachers. To select the participants, we employed purposive sampling with a convenience case strategy. Through thematic analysis (Braun and Clark, 2006), we identified three major themes of factors influencing the participants’ speaking anxiety, including 1) language barrier (Grammar, vocabulary, pronunciation, and fluency); 2) psychological issues (low motivation, and personality); and 3) learning proponents (lecturers, classmates, and unfamiliar topic). To alleviate their anxiety, the participants have undertaken strategies, such as 1) self-management (self-practice and doing positive activities) and 2) getting-help strategies (friends’ help and motivation).

Abstract

This study aims to analyze the role of organizational communication and leadership style in managing conflict in the organizational environment. By using a qualitative descriptive method, the research conducted is a qualitative descriptive study that aims to find and describe an activity that is carried out.This research is included in the type of library research, namely research whose activities are related to collecting data through literature, or research that explores the object of study by relying on various information from library sources.The results of the study indicate that open, transparent, and inclusive organizational communication can minimize the potential for conflict caused by miscommunication or lack of understanding between individuals or groups. In addition, transformative and participatory leadership styles have proven to be more effective in managing conflict than authoritarian leadership styles. Leaders who are able to listen, provide space for member participation, and make decisions fairly can create a conducive and harmonious work atmosphere.

Abstract

More than 40 species of bamboo were known from the Lesser Sunda Islands (LSI), including several endemic species. Endemic species are often highly specialized, found in limited geographical areas, and vulnerable to extinction if their habitat is destroyed. This study aimed to provide an account of endemic bamboo species on the LSI. Fieldwork involved collecting samples of bamboo in the LSI. Herbarium specimens of bamboo deposited in the Herbarium Bogoriense (BO), collected from the LSI were examined, and endemic LSI species were recorded. The conservation status followed the International Union for Conservation of Nature (IUCN) red list categories and criteria. The conservation status of unassessed species was evaluated using IUCN red list categories and criteria. A spatial analysis was also conducted. Data were analyzed and presented descriptively. There are 10 endemic bamboo species in the LSI, namely Bambusa ooh Widjaja & Astuti from Bali (conservation status: endangered), Chloothamnus reholttumianus (Soenarko) Widjaja from Sumba (vulnerable), C. schmutzii (S.Dransf.) Widjaja from Sumbawa and Flores (near threatened), Dinochloa kostermansiana S.Dransf. from Sumba and Flores (near threatened), D. sepang Widjaja & Astuti from Bali (vulnerable), Fimbribambusa rifaiana Widjaja from Alor (near threatened), Gigantochloa aya Widjaja & Astuti from Bali (vulnerable), G. baliana Widjaja & Astuti from Bali (vulnerable), G. taluh Widjaja & Astuti from Bali (vulnerable), and Schizostachyum purpureum Damayanto & Widjaja from Sumba (data deficient). They can be found at an altitude of 20–1700 m in various habitats, including forests, bamboo forests, villages, botanical gardens, along a road, slopes, valleys, riverbanks, and around a lake.

Abstract

Lipid is an important biomolecule in plant because of their structural and functional roles in plant cells. Moreover, lipid could be a signal molecule in defense system of plants under biotic and abiotic stresses. Detoxification process of toxic substances, which is one of the defense system and controlled by various genes, plays an important role in tolerance mechanism in plant under stress conditions, including iron (Fe) toxicity. Plants develop various tolerance strategies to cope the Fe toxicity. The objective of this research was to investigate the expression of OsPLA2-III and OsPPO genes under Fe stress condition. Two-weeks-old seedlings of two rice varieties, i.e., IR64 (Fe-sensitive toxicity) and Pokkali (Fe-tolerant toxicity) were used. Both varieties were treated with 1 (control) and 400 ppm of Fe in the form of FeSO4.7H2O in the nutrient culture solution. The leaf bronzing, chlorophyll content, and relative expression of OsPLA2-III and OsPPO genes were observed. An in-silico study was also performed to predict the interaction between OsPLA2-III and OsPPO proteins. The results showed that the Fe toxicity induced leaf bronzing, reduced leaf chlorophyll content, and increased the OsPLA2-III and OsPPO gene expression levels. Both genes are suggested to have a role in plant tolerance mechanism during Fe toxicity stress via lipid signaling pathway.

Abstract

Melona, Tacapa Gold, and Gama Melon Parfum are novel Melon genotypes that have been introduced for cultivation in the saline-prone coastal region of Bocor Beach, Kebumen, Central Jawa. Elevated salt concentrations in the area pose challenges, impacting yield. The potential of these new genotypes for saline land remains unexplored. This study aimed to assess the morphophysiological and molecular responses of these genotypes to salinity stress. Seeds were germinated in cocopeat and ABmix 3000 solution and treated with 220 mM NaCl until harvest. The analysis included morphology, chlorophyll content, proline accumulation, malondialdehyde levels, and gene expression were analyzed. After 1 week of salinity stress, the results showed reduced plant height, leaf number, stomatal density, percentage of opened stomata, and width and length of leaves. The malondialdehyde, proline, and root-shoot dry mass ratio increased. The expression of CSD1-1, P5CR, and late embryogenesis abundant genes increased under salinity treatment. Gama Melon Parfum exhibits salt tolerance, as indicated by higher P5CR gene expression, proline accumulation, and leaf-relative water content. P5CR gene expression, proline accumulation, and leaf-relative water content are valuable indicators of salt tolerance for assessing melon genotypes.
