Abstract

Birds are powerful biodiversity indicators due to their wide distribution and responsiveness to environmental pressures. Building on prior reviews, we synthesize methodological advances to update the Multi-species Bird Index (MSI) field. This study recaps limitations like European/breeding-season biases and uncertainty gaps while integrating recent studies that expand analytical rigor. Advances in passive acoustic monitoring, remote sensing, and trait-based models now improve species selection and reduce detectability errors. We translate these into practical guidance for policy application and a research agenda emphasizing seasonal completeness. The synthesis underscores birds’ role as decision ready barometers and provides a blueprint for robust monitoring. Birds serve as premier biodiversity barometers due to their cosmopolitan distribution and sensitivity to anthropogenic pressures. However, traditional Multi species Bird Indicators (MSIs) often suffer from significant Europe-centric and breeding-season biases that limit their global policy impact. This study synthesizes recent methodological breakthroughs to update the MSI framework. We evaluate the integration of Passive Acoustic Monitoring (PAM), high-resolution remote sensing (ALS LiDAR), and trait-based selection criteria into standard monitoring protocols. Our synthesis reveals that combining automated sensor networks with hierarchical Bayesian models effectively mitigates detectability errors and fills critical data gaps in under-represented regions. Furthermore, linking avian indicators with carbon sequestration and equity metrics allows for more robust prioritization of Nature based Solutions (NbS). We provide a practical blueprint for next-generation indicators that emphasize seasonal completeness and statistical rigor. By shifting from retrospective reports to forward-looking policy tools, these refined barometers can more accurately track progress toward global biodiversity targets.

Abstract

Conflict between local communities and wildlife in the buffer villages surrounding Bogani Nani Wartabone National Park (TNBNW) continues to rise due to increasing human pressure on forest ecosystems. This study aims to identify the types of conflict, the wildlife species involved, and community responses to these disturbances. Data were collected through interviews with 30 respondents in East Suwawa and West Dumoga Subdistricts. Results show that most conflicts (90%) are triggered by wildlife perceived as agricultural pests, while 10% are caused by animals entering residential areas. Key species involved include the crested black macaque (Macaca nigrescens), Sulawesi wild boar (Sus celebensis), snakes, lowland anoa (Bubalus depressicornis), and various bird species. Reported disturbances range from crop damage and wildlife presence in farmlands to potential threats to human safety. Most community mitigation efforts are non-lethal, such as installing nets, using spiritus as a repellent, guarding fields with dogs, and setting simple traps. However, hunting still occurs in some areas for crop protection or economic purposes. Habitat loss from encroachment, logging, and land clearing exacerbates conflict by pushing wildlife out of forests into human landscapes. Overall, these findings demonstrate that human–wildlife conflict leads not only to economic losses but also threatens the survival of protected species such as Macaca nigrescens (VU), Sus celebensis (NT), and Bubalus depressicornis (EN). This study demonstrates scientific novelty by presenting an integrated empirical analysis of the forms of human–wildlife conflict, the composition of species involved, and community response patterns in buffer villages surrounding Bogani Nani Wartabone National Park that have not previously been systematically documented, and provides practical contributions by offering an evidence-based foundation for the development of adaptive, non-lethal, and community-based conflict mitigation strategies to support conservation area management and the protection of threatened species.

Abstract

Numeracy literacy is a fundamental competence that enables students to use mathematical concepts, procedures, facts, and tools in various life contexts. This community service activity aimed to strengthen teachers' initial understanding of the Education Report and data-based planning to support numeracy improvement. The activity was conducted on 8 May 2024 in the computer laboratory of SMP Negeri 1 Kabila Bone and involved 20 teachers. It consisted of preparation, material presentation, demonstration of indicator interpretation, discussion, and process evaluation. Participants actively discussed how to read achievement information, identify priority problems, reflect on possible root causes, and formulate follow-up actions through the Identify, Reflect, and Improve stages. The activity produced initial conceptual strengthening, but it did not measure changes in teachers' competence or students' numeracy outcomes. Continued mentoring, action-plan development, and measurable evaluation are therefore required.

Abstract

Penelitian ini bertujuan untuk menganalisis diversitas dan distribusi spasial tutupan lahan di Daerah Aliran Sungai (DAS) Limboto, khususnya Sub DAS Biyonga, pada rentang waktu 2009–2024. Analisis dilakukan untuk mengetahui tingkat keragaman spasial serta dinamika perubahan tutupan lahan selama periode tersebut. Metode yang digunakan adalah Sistem Informasi Geografis (SIG) untuk memetakan, mengklasifikasikan, dan membandingkan perubahan tutupan lahan antar tahun pengamatan. Hasil penelitian menunjukkan bahwa pada tahun 2019, terjadi pergeseran struktur tutupan lahan di Desa Biyonga: hutan sekunder meningkat menjadi 32%, semak belukar menurun menjadi 21%, dan pertanian campur semak bertambah menjadi 25%. Perubahan ini membuat nilai SHDI naik menjadi 1,647, namun nilai tersebut menunjukan hasil sedang tetapi  masih tergolong rendah, yang berarti tingkat heterogenitas lanskap belum mencapai kondisi yang benar-benar beragam. Kenaikan SHDI ini hanya menunjukkan adanya sedikit peningkatan variasi spasial, bukan transformasi besar yang menciptakan lanskap kompleks. Sedangkan, pada tahun 2024, komposisi tutupan lahan di Desa Biyonga relatif stabil dibandingkan kondisi tahun 2019: hutan sekunder tetap berada pada 32%, pertanian campur semak pada 25%, dan semak belukar pada 21%. Nilai SHDI masih berada pada angka 1,647, yang meskipun menunjukkan konsistensi pola dari tahun 2019, tetap tergolong rendah berdasarkan standar ekologi lanskap. Kategori SHDI ini mengindikasikan bahwa tingkat heterogenitas lanskap belum mencapai keragaman yang tinggi, karena distribusi tutupan lahan masih terfokus pada beberapa kelas dominan dan persebarannya belum merata.

Abstract

Macaca hecki merupakan spesies primata endemik Pulau Sulawesi, yaitu monyet hitam Sulawesi yang populasinya kini terancam akibat deforestasi, fragmentasi habitat, dan konflik dengan manusia karena perambahan serta persaingan terhadap sumber pakan, terutama tanaman budidaya. Penelitian ini bertujuan menganalisis vegetasi tumbuhan pakan Macaca hecki di kawasan penyangga Suaka Margasatwa Nantu Gorontalo, Indonesia. Metode penelitian deskriptif kuantitatif, dengan analisis vegetasi berbasis purposive random sampling serta pembagian petak contoh untuk strata semai, pancang, dan pohon. Data dikumpulkan melalui survei vegetasi lapangan, identifikasi jenis tumbuhan, dan perhitungan Indeks Nilai Penting (INP). Hasil penelitian menunjukkan bahwa buah merupakan organ tumbuhan yang paling dominan dikonsumsi oleh Macaca hecki, dengan sumber pakan budidaya memiliki proporsi lebih besar (65%) dibandingkan sumber alami (35%). Pada tingkat pohon, Leucaena leucocephala memiliki nilai INP tertinggi (111,31%), diikuti oleh Arenga pinnata (69,11%), sedangkan Carica papaya (145,54%) mendominasi tingkat pancang dan Physalis angulata (149,04%) mendominasi tingkat semai. Jenis-jenis tumbuhan berbuah cepat tumbuh ini menyediakan sumber energi penting serta dukungan struktural bagi habitat. Namun, ketergantungan yang tinggi terhadap tumbuhan budidaya dapat mengubah perilaku mencari makan alami Macaca hecki, yang berpotensi mengurangi keragaman pakan dan kemampuan adaptasi ekologisnya. Hasil penelitian ini menegaskan pentingnya pengelolaan vegetasi terpadu di kawasan penyangga untuk menyeimbangkan antara spesies asli dan budidaya, guna menjamin stabilitas ketersediaan pakan dan mengurangi konflik antara manusia dan satwa liar.
