Abstract

Examining ethnobotany in mountainous regions established as popular hiking destinations is essential for conservation initiatives. In this study, we aim to explore the ethnobotanical knowledge of the indigenous communities and to analyze the plant diversity in the ecotourism corridor to Mount Prau in Purwosari Village, Central Java, Indonesia. Ethnobotanical data was collected through semi-structured interviews with informants recruited via purposive sampling. An exploratory approach was used to inventory plant diversity along the ecotourism corridor of Mount Prau in Purwosari village. Our key informants comprised village officials, community leaders, Mount Prau caretakers, and basecamp managers. The findings indicated that the informants explained a total of 68 plant species, which were utilized by the community for various purposes. These plants served as valuable food sources, medicinal ingredients, and economic value, and they were also used for fodder, building materials, shade, and conservation purposes. In the ecotourism corridor in Purwosari village, which serves as the conservation trail for Mount Prau, a total of 117 plant species were identified through an inventory in this study. Finding some invasive alien plant species, such as Acacia decurens and Clidemia hirta, and an endangered species, Castanopsis argentea, highlights the importance of conservation efforts for protecting and preserving the diverse plant species found along the conservation trail to Mount Prau.

Abstract

Unprocessed leftover cassava wastes from the home industries in Pomahan Village in Bojonegoro, East Java, has become a serious problem as a pollutant to the environment. This study examined the quality of bio-briquettes made from cassava skin waste with its epidermis starch as an adhesive agent, or binder. The aim is to assess the quality of the bio-briquettes for alternative energy sources and their suitability from an economic point of view. The utilized research method was a descriptive quantitative approach by measuring water and ash content, calorific value test, and economic feasibility calculation. The results indicated that the highest calorific value of 5337.83 cal/g was obtained from a bio-briquette mix of 50 g cassava skin with 5% epidermis starch binder. This bio-briquette also possesses the lowest water and ash contents of 2.75 and 8%, respectively, compared to other mixtures. The economic feasibility calculation showed a BEP value of 423 kg/ month, B/C Ratio of 6.14-fold, ROI of 30%, and PBI of 0.2 years. In conclusion, cassava-based bio-briquettes are economically promising and environmentally friendly due to their biomass property and help to tackle the environmental problem due to the cassava waste.

Abstract

The Indonesian purple rice (IPR), a crossbreeding of black and white rice, is a potential source of ferulic acid. Up to this point, the genomic similarity between the crossbreeding and its parentals has not been determined, particularly in genes involved in ferulic acid biosynthesis. In this present work, we analysed the profile of Oryza sativa caffeic acid-O-methyltransferase (OsCOMT) gene in IPR. The genomic DNA was extracted by CTAB method, then amplified with a specific primer of OsCOMT gene. The amplicon was sequenced by Sanger method and confirmed by geneID NC_029259.1. The IPR showed an amplicon of 708 bp sequence of the OsCOMT gene, indicating the gene involved in ferulic acid biosynthesis. The IPR gene profile is similar to the parentals, but there are variations in point mutations that distinguish it from the parentals. Aspartic acid was changed to Glutamine by mutations at positions 52, 69, and 79. We suggest that IPR has a novel OsCOMT gene variant that is unique as it is the crossbreed.
