Abstract

The Mataram University campus has shade trees in almost all area units, some of which are still quite ideal and some of which show problems with tree architecture deviations, such as trunk declivity and canopy inclination, which can cause the risk of tree fall. This study was conducted to analyze the distribution of tree fall risk based on tall, trunk declivity and canopy inclination on the Mataram University campus. The sample area was taken using the purposive sampling method and then sampling trees in each sample area unit using the quarter method. Tree variables observed were tall, trunk declivity and canopy inclination. The data were processed respectively to produce tree tall, trunk declivity, and canopy inclination classes. These data were then further analysed in an integrated manner to produce a value of tree-fall hazard risk. These tree-fall hazard values were interpreted into 5 categories, namely not hazardous, somewhat hazardous, quite hazardus, hazardous, and very hazardous. The results show that of the 108 shade trees on the Mataram University campus, 38.01% of the trees were in categories requiring immediate attention or action (moderately hazardous to very hazardous). Zone 1 was the only zone with the highest risk (0.93% very hazardous).

Abstract

Lombok Island, particularly the Kawasan Ekonomi Khusus (KEK) Mandalika, has rapidly developed as a global tourist destination, attracting a significant annual increase in visitor numbers. This growth necessitates the provision of adequate facilities, especially sanitation facilities, which play a crucial role in enhancing visitor comfort and experience as well as supporting sustainable tourism principles. This study aims to identify the availability of sanitation facilities and analyze sanitation quality at KEK Mandalika through a quantitative approach. Data collection was conducted using checklists to evaluate facility conditions and laboratory tests to measure water quality parameters such as pH, total dissolved solids (TDS), and salinity. The results indicate that several sanitation facilities have not met comfort standards and require improvement. Water quality based on tested parameters showed pH within normal ranges, TDS exceeding quality standards, and salinity tests indicating brackish water with low salinity. This research highlights an urgent need to enhance facilities, particularly those that are disability-friendly, to support inclusive comfort and accessibility, as well as to improve clean water quality. With such facility improvements, KEK Mandalika is expected to maintain its reputation as an environmentally friendly, safe, and high-quality tourist destination. The findings also offer recommendations for infrastructure enhancement and easier access, which ultimately can minimize the environmental impact of tourism activities.

Abstract

Dasan Geria Utara Hamlet exhibits significant potential for organic waste generation, primarily Organic biomass such as foliage litterand domestic kitchen residues. Currently, waste management practices in this region remain suboptimal, thereby adversely affecting environmental sanitation. Concurrently, the local community encounters challenges regarding the availability and accessibility of synthetic fertilizers. Hence, an intervention program focusing on organic fertilizer production is imperative to mitigate reliance on chemical fertilizers and to optimize the utilization of available domestic waste streams. This community service project aimed to enhance public knowledge and technical proficiency in manufacturing organic fertilizers. The initiative was executed in three sequential phases: preparation, practical demonstration of organic fertilizer production, and evaluation. The methodologies deployed included socialization, Focus Group Discussions (FGD), and hands-on participatory training guided by experts. The program was successfully implemented, characterized by high participant engagement. The empirical outcomes indicated a substantial increase in the community's literacy regarding the dichotomy between synthetic and organic fertilizers, alongside enhanced technical skills in composting. Evaluation metrics revealed that all participants comprehensively understood the ecological impacts of chemical fertilizers, the advantages of organic alternatives, and successfully demonstrated the capacity to generate organic fertilizer from household waste utilizing easily replicable home-based methods. This program is expected to drive a paradigm shift by reducing synthetic fertilizer dependency and increasing organic fertilizer adoption in Dasan Geria Utara Hamlet, Dasan Geria Village. Ultimately, this capacity-building initiative empowers the community to leverage localized resources, fostering a more sustainable environmental ecosystem.
