Abstract

This research was conducted in the Utilization Block of the Kerandangan Nature Tourism Park, West Lombok, to analyze the abundance and feeding preferences of butterflies of the family Nymphalidae. The background of the study is based on the important role of butterflies as pollinators as well as bioindicators of ecosystem health, and the limited recent data regarding their diversity in this area. The methods used include species identification using the time search technique and vegetation analysis using double-square plots to determine the types of host plants. The data were analyzed descriptively and quantitatively through diversity, evenness, species richness, similarity, dominance indices, as well as feeding preferences and importance value indices. The study recorded 112 individuals from 28 butterfly species. The habitat with the highest abundance was Open Spaces (35 individuals, 17 species), while the lowest was in Secondary Forest (12 individuals, 8 species). The highest Shannon-Wiener diversity index was recorded in Open Areas (H’=2.73; moderate category). Butterfly feeding preferences were dominated by flowers from the families Asteraceae, Acanthaceae, Fabaceae, Moraceae, and Apocynaceae, with Ageratum conyzoides being the most preferred nectar source. Around 90% of butterflies used flowers as an energy source, while 10% consumed decaying fruit. In conclusion, the Kerandangan Nature Reserve has a fairly high diversity of Nymphalidae butterflies, with the availability of flowering vegetation being a key factor in species abundance and distribution.

Abstract

This study evaluated the health of trees in the green belt of Mataram City with a focus on root, stem and crown conditions. The research, which took place from December 2024 to February 2025, aimed to identify at-risk trees and develop effective protection strategies to reduce damage to the city's green belt. The Visual Tree Assessment (VTA) method was used to collect data, based on the International Society of Arboriculture (ISA) criteria. The research findings emphasize environmental impacts on tree health, including urban activities and extreme weather. This research emphasizes the importance of public education to improve the resilience of urban ecosystems and reduce the risk of tree-related incidents, as well as contributing to urban planning and environmental management to ensure the sustainability of green spaces in Mataram.

Abstract

This community development program was motivated by the large amount of broken pottery waste generated during the firing process that remains unutilized in the traditional pottery industry of Banyumulek Village. The clay waste has significant potential as an innovative additive in the production of natural soap. The purpose of this activity was to enhance community awareness and skills, particularly among members of KSL Rinjani Lombok, in processing waste into environmentally friendly and economically valuable products. The implementation methods included socialization and training. The socialization stage provided understanding of the potential of clay waste and opportunities for developing natural soap products, while the training stage was conducted through hands-on practice covering material preparation, mixing with soap base ingredients, and soap molding techniques. The results of the activity showed an increase in participants’ knowledge and skills in utilizing clay waste, with the highest improvement reaching 85%. Community partners were able to produce natural soap with good quality and market potential. In addition, the program successfully achieved its objectives by empowering the community through innovative utilization of pottery waste, while fostering the creation of competitive and eco-friendly product.

Abstract

East Pemenang Village, located in Pemenang District, North Lombok Regency, possesses substantial potential in coconut processing; however, most of the harvest is still sold in raw form, resulting in low added value. The Al-Amin Joint Business Group (KUB), which has initiated coconut-based processing such as briquettes and cocopeat, continues to face challenges related to limited technology, insufficient product diversification, and restricted market access. This community engagement program aims to enhance the efficiency of an integrated coconut processing system, develop value-added products such as tropinata beverages, nata de coco, coconut-based soap, and coconut-shell charcoal briquettes, as well as strengthen market linkages. A Supply Chain approach was adopted to integrate upstream and downstream processing activities. The program involved Focus Group Discussions (FGDs), technical training on modern processing technologies, the implementation of new technologies, and continuous mentoring to ensure optimal operational performance. Expected outcomes include product diversification—such as tropinata and coconut-based soap—and increased production capacity, including briquette output reaching 100 kg/day and nata de coco up to 50 liters/day. Furthermore, the program aims to empower the community of East Pemenang Village, improve economic well-being, and establish a sustainable local enterprise ecosystem.
