Traditional knowledge of wild and semi-wild edible plants used in Bali (Indonesia) to maintain biological and cultural diversity

Abstract: We report the first ethnobotanical study of wild and semi-wild food plants used by the inhabitants of the villages of Bali. Considering the urgent need to avoid the loss of this traditional knowledge, 50 informants from 13 “Bali Aga” villages across four districts were selected for our field investigation. Ethnobotanical data were collected through different interview methods (direct observation, semi-structured interviews, key informant interviews, individual discussions, focus-group discussions, and questionnaires). The 86 recorded species belonging to 41 families and 68 genera, including angiosperms (82) and pteridophytes (4), are categorized as wild (33) and semi-wild (53), of which 63.64% are native to Malesian, Indian, and Indochinese. Wild and semi-wild edible plants play an important role in providing the Balinese with various essential nutrients. Fourteen species (16.28%) are also used medicinally. In recent years, with the growth of the tourist industry, the wild habitats of edible plants have b...

Indonesian universities in transition: catching up and opening up

Abstract: Indonesia's higher education system is changing rapidly: in 2010 there were about 5 million students, up from 2,000 in 1945. Effectively the tertiary system has four tiers, three of which are within the public sector. However, the system is increasingly private sector driven. The key themes of this paper on universities are rapid growth; overcoming the historical backlog; and the need for further fundamental reform. The quality of Indonesia's tertiary institutions is highly variable. Governance structures and incentives regimes within the state universities are complex and obscure. The government both over-regulates and under-regulates. Major reforms are under way and increasing financial resources are available.

Lecturers’ Understanding on Indexing Databases of SINTA, DOAJ, Google Scholar, SCOPUS, and Web of Science: A Study of Indonesians

Abstract: The Ministry of Research, Technology and Higher Education of Indonesia has introduced several national and international indexers of scientific works. This policy becomes a guideline for lecturers and researchers in choosing the reputable publications. This study aimed to describe the understanding level of Indonesian lecturers related to indexing databases, i.e. SINTA, DOAJ, Scopus, Web of Science, and Google Scholar. This research used descriptive design and survey method. The populations in this study were Indonesian lecturers and researchers. The primary data were obtained from a questionnaire filled by 316 lecturers and researchers from 33 Provinces in Indonesia recruited with convenience sampling technique on October-November 2017. The data analysis was performed using frequency distribution tables, cross tabulation and descriptive analysis. The results of this study showed that the understanding of Indonesian lecturers and researchers regarding publications in indexing databases SINTA, DOAJ, Scopus, Web of Science and Google Scholar is that, on average, 66,5% have known about SINTA, DOAJ, Scopus, Web of Science and Google Scholar. However, based on empirical frequency 76% of them have never published with journals or proceedings indexed in Scopus.

Microwave-assisted synthesis of carbon dots from eggshell membrane ashes by using sodium hydroxide and their usage for degradation of methylene blue

Abstract: Carbon dots (C-dots) is a recent member of carbonaceous nanomaterial with particle size below 10 nm, equipped with unique fluorescent properties under UV light irradiation. Many methods for the production of C-dots have been reported by introducing carbon-rich waste. In this work, a facile and rapid method was developed to synthesize C-dots from the ashes of eggshell membrane (ESM) in sodium hydroxide solution assisted by one-step microwave irradiation. The optimum time in preparing the C-dots and the highest photoluminescence intensity are achieved for 1 min and by using 1 mol L−1 NaOH, respectively. The resulting C-dots with an average size of 3.88 ± 0.56 nm exhibited pH and NaOH solvent-dependent fluorescent behaviour in the visible light range. They are found to be able to degrade methylene blue under sunlight irradiation, with increasing degradation ranging from 26% to 43% for 5 ppm to 1 ppm concentration of methylene blue.
