Abstract

Butterflies are insects that live in various ecosystems. Healthy ecosystems tend to have a high diversity of butterfly species, due to the diversity of plants as food sources and breeding places. Permaculture, as a sustainable agricultural system, has three basic ethics that focus on caring for the earth, caring for people, and sharing fairly. This ethic provides space for other living creatures, including butterflies, to develop and maintain ecosystem balance. The aim of this research is to determine the type of butterfly, diversity, abundance, richness, and types of host plants in the caterpillar phase. The method used in this research is purposive exploration, with data analysis using the Shannon-Wienner diversity index (H') and evenness index to assess the diversity and stability of the ecosystem. The results of the research show that there are 85 types of plants that make up Lombok Permaculture, with 25 types of host plants and 35 types of butterflies. The value of the Shannon-Wienner diversity index is relatively low, namely 0.82, which indicates that the diversity of butterfly species is still limited. The evenness index is also relatively low at 0.23, which indicates the stability of an ecosystem that is still vulnerable to disturbance. However, the richness index shows a fairly high value, namely 7.12, which means that the area has many species

Abstract

Birds have a vital ecological role as pollinators, seed dispersers, and insect population controllers. Their diversity is super important in ecology and conservation studies. This study aims to identify and analyze the bird community structure in the Special Purpose Forest Area of Muhammadiyah University of Mataram. Field surveys were conducted in June 2025 using the point count method at four observation points selected through purposive sampling. Observations were carried out over three time periods with two repetitions at each point. The study recorded 26 bird species from 23 families, totaling 177 individuals. Dominant species included Pycnonotus goiavier, Orthotomus sepium, and Todiramphus chloris. Additionally, endemic species of Nusa Tenggara such as Otus jolandae and Pitta concinna were recorded. Ecological analysis showed a Shannon-Wiener diversity index of 2.99, a Margalef species richness index of 4.83, and an Evenness index of 0.92. These values reflect a stable, healthy bird community with an even distribution of individuals without the dominance of any particular species. Based on these findings, this study recommends strengthening conservation efforts through the preservation of natural vegetation, regular monitoring of bird populations, and further research.

Abstract

The Special Purpose Forest Area of the University of Muhammadiyah Mataram has the potential to be a location for education and biodiversity conservation. This study aims to analyze diversity, species richness, and evenness of vegetation as indicators of forest ecosystem conditions. The study was conducted in June 2025 using a quantitative descriptive approach in 16 observation plots across four growth strata. The analysis was carried out using the Shannon-Wiener index for diversity, Margalef for species richness, and Pielou for evenness. The results showed that the tree stratum had a value of H' = 2.703, R = 5.951, and E = 0.780, reflecting a vegetation community with high and even diversity and distribution of individuals. In contrast, the seedling stratum showed very low values of H' = 0.049, R = 1.443, and E = 0.071, indicating the dominance of certain species and limited natural regeneration. Overall, 44 species from 24 families with a total of 236 individuals were identified. This pattern indicates an unbalanced vegetation structure across strata, with higher community stability at the tree level compared to younger growth levels. This finding provides a scientific basis for sustainable forest management and conservation planning.

Abstract

ABSTRAKPermasalahan sampah merupakan permasalahan yang banyak melibatkan berbagai pihak dalam pengelolaannya terutama di Tempat Pembuangan Akhir (TPA). Salah satu langkah dalam melakukan pengelolaan sampah adalah dengan melakukan identifikasi berbagai permasalahan yang dihadapi pihak pengelola bersama masyarakat sekitar TPA.  Oleh karena itu, Kegiatan Pengabdian ini bertujuan untuk mengidentifikasi tantangan pengelolaan sampah di Tempat Pembuangan Akhir (TPA) Regional Kebon Kongok di Desa Sukamakmur, Lombok Barat. Metode yang digunakan dalam kegiatan ini adalah metode observasi dan wawancara di lokasi TPA. Kegiatan ini banyak melibatkan berbagai pihak terutama pihak pengelola TPA bersama masyarakat sekitar. Berdasarkan kegiatan iniditemukan bahwa distribusi sampah di TPA ini tidak merata, dengan adanya titik-titik kritis dan zona penumpukan sampah yang memerlukan perhatian khusus. Infrastruktur pengelolaan sampah yang terbatas, seperti fasilitas pemrosesan yang kurang, juga menjadi hambatan utama. Dampak lingkungan dan sosial ekonomi dari TPA ini belum sepenuhnya tergambarkan secara rinci, namun ada indikasi dampak sosial ekonomi terhadap masyarakat sekitar. Partisipasi masyarakat dalam program pengelolaan sampah masih rendah, dipengaruhi oleh persepsi negatif terhadap sampah dan ketidakpastian terkait manfaat partisipasi. Sebagai solusi, edukasi dan kesadaran masyarakat menjadi kunci untuk meningkatkan partisipasi. Penyesuaian program dengan konteks lokal dan pemberdayaan masyarakat melalui pendekatan inovatif juga diusulkan. Kata kunci: pengelolaan sampah; tempat pembuangan akhir; analisis data spasial ABSTRACTThe waste problem is a problem that involves many parties in its management, especially at final disposal sites (TPA). One of the steps in managing waste is to identify various problems faced by the management together with the community around the landfill. Therefore, this Community Service Activity aims to identify the challenges of waste management at the Kebon Kongok Regional Final Disposal Site (TPA) in Sukamakmur Village, West Lombok. The method used in this activity is the method of observation and interviews at the landfill location. This activity involves many parties, especially the landfill management and the surrounding community. Based on these activities was found that waste distribution in this landfill is uneven, with critical points and zones of waste accumulation requiring special attention. Limited waste management infrastructure, such as insufficient processing facilities, also poses a major obstacle. The environmental and socio-economic impacts of this landfill have not been fully detailed, but there are indications of socio-economic effects on the surrounding community. Community participation in waste management programs is low, influenced by negative perceptions of waste and uncertainty about the benefits of participation. As a solution, community education and awareness are key to increasing participation. Adjusting programs to local contexts and empowering communities through innovative approaches are also proposed. Keywords: waste management; landfill; spatial data analysis
