Abstract

This study aims to identify and describe the biological aspects within the tradition of nyale scent through the indigenous knowledge of the community. The research utilizes a qualitative method with a phenomenological approach, focusing on collecting data regarding the nyale scent tradition. Data on indigenous knowledge were obtained through interviews with three sources: traditional leaders, village heads, and participants in the nyale scent tradition. The data were collected in narrative form and analyzed descriptively. The research findings indicate that the nyale scent tradition is relevant to biology, observed in various aspects such as the process of capturing nyale worms, the biology of nyale worms, and the utilization of nyale worms. Relevant biological topics associated with the nyale scent tradition include the classification of living organisms, ecosystems, reproduction, the human digestive system, and the structure and function of plants.

Abstract

The Sembalun Mushroom Initiative aims to strengthen food security and resilience to disasters in Sembalun Bumbung and circumstance villages through the utilization of biogas energy for the pasteurization process of mushrooms. These areas are prone to disasters, making the supply of food and sustainable energy a major challenge. The project utilizes cow dung waste as an environmentally friendly biogas source to support pasteurization and mushroom cultivation. Traditionally, mushroom pasteurization processes still use firewood, which triggers deforestation, high carbon emissions, and health risks from smoke. The community service team from the University of Mataram has developed biogas technology as an alternative solution. The biogas installation at the At-Tazkiyah Islamic Boarding School was completed in May 2024 and began operating in July 2024, thereafter a mushroom house has been built for mushroom cultivation in early 2025. During this community service project, a gas pasteurization system is installed and used for pasteurization, followed by training and capacity building for the community in utilizing green energy sources. The aim is to introduce a transition to environmentally friendly technologies, as well as to support innovation, sustainability, and community engagement. The activities are an international collaboration between the Postgraduate Program and the Faculty of Engineering at University of Mataram and the Fatoni University in Thailand. It is expected to expand Unram's international exposure and strengthen cooperation between countries.

Abstract

Mangroves are tropical plants found in saline environments and have a function in regulating CO2 and O2 in the atmosphere. The aim of this research is to assess the community structure and carbon content of mangrove species in natural locations and revegetation results in Bagek Kembar, Sekotong, West Lombok. The research method uses transect and quadrat methods. The first data analysis was descriptive and then used carbon content analysis from the International Panel on Climate Change. The results of the research found 10 species of mangroves in natural locations, namely Avicennia alba, Avicennia marina, Bruguiera gymnorrhiza, Ceriops decandra, Excoecaria agallocha, Rhizophora apiculata, Rhizophora mucronata, Rhizophora stylosa, Sonneratia alba, and Sonneratia caseolaris, and in the revegetated locations were Avicennia marina, Rhizophora apiculata, Rhizophora mucronata, and Rhizophora stylosa. Furthermore, the seedling category has the highest density in natural mangrove locations with a total of  37976,19 individuals/Ha and in revegetated locations of 22361,11 individuals/Ha.  The mangrove species that dominates in natural locations is the Avicennia marina species and in the revegetation results is the Rhizophora stylosa species based on frequency, density and dominance values. The highest biomass value in natural mangroves was obtained from the Avicennia marina species at 52,870 tonnes/ha, while in revegetated mangroves it was obtained from the Rhizophora stylosa species at 29,747 tonnes/ha. Furthermore, the total carbon content in natural mangrove locations is 59,329 tonnes C/ha or equivalent to carbon absorption of 183,018 tonnes CO2/ha. Meanwhile, the total carbon content in revegetated mangrove locations is 21,877 tonnes C/ha or comparable to carbon absorption of 80,290 tonnes CO2/ha. The research conclusion shows that the species that dominates and has the highest carbon content in natural locations is the Avicennia marina species and in revegetated locations is the Rhizophora stylosa species.
