Abstract

Urbanization drives biodiversity loss, but green spaces in Pontianak City may still serve as important refuges for butterflies. This study aims to assess butterfly species richness across different habitat types in Pontianak City, including agricultural, agroforestry, city parks, suburban areas, and marginal lands. Data were collected using the time-constrained counts method with a 30-minute observation period per site. Species richness was estimated using Chao1 estimator, diversity was analyzed with Hill numbers, and species composition was compared using the Chao-Sørensen similarity. A total of 438 individuals from 50 species were recorded. Agroforestry, suburban areas, and city parks exhibited relatively similar levels of species richness (28, 26, and 25 species, respectively), with agroforestry demonstrating the highest species richness and diversity (Shannon = 20, Simpson = 16). Conversely, agricultural areas (14 species) and marginal lands (7 species) showed comparatively lower species richness. The highest estimated species richness was found in city park habitats (36 species). Agricultural and marginal lands had the highest species similarity (0.77), whereas agroforestry and marginal lands had the lowest (0.22). These findings highlight agroforestry, suburban areas, and city parks as key conservation areas for butterflies. Habitat management strategies should prioritize these habitats to support butterfly diversity in Pontianak City.

Abstract

Fingerprints are utilized for personal identification, as well as to identify ethnicity, blood type and gender. They are permanent and remain unchanged throughout lifetime, unless an injury causes skin damage. This study aims to examine the variation in fingerprint patterns among students at OSO University, considering ethnic and gender differences. This study used a purposive sampling method and at least 50 fingerprint samples from students at the Faculty of Natural Sciences and Marine Science, OSO University. Generally, the loop fingerprint pattern is found in approximately 54.67% of the total sample of students. The loop fingerprint pattern is most commonly found in the Bugis, Malay and Javanese ethnic, while the Dayak ethnic predominantly has the whorl pattern. The arch fingerprint pattern is only found in the Dayak ethnic group. It can be assumed that the arch pattern may act as a distinguishing characteristic among ethnic groups in West Kalimantan. This study can contribute to forensic science, especially in identifying individuals based on fingerprint patterns associated with ethnicity and gender.  This research can provide as a foundation for further studies that explore the relationship between fingerprint patterns and other demographic factors, such as age or geographic location.

Abstract

Coastal waters are vital for aquatic life and human activities, yet their quality is highly susceptible to environmental pressures. Because macrozoobenthos are sensitive to environmental changes and have limited mobility, they are frequently utilized as bioindicators. This study aims to examine the structure of the macrozoobenthos community in the waters of Sungai Kakap Village, Kubu Raya Regency, and its relationship with environmental parameters. Samples were collected at five stations using purposive sampling with line transects and quadrants, then analyzed for density, diversity (H'), evenness (E), and dominance (C). A total of 14 species were found with distinct dominant patterns across stations, notably the high dominance of Neritina violacea, Corbicula fluminea, and Corbicula fluvitalis at Stations I, III, and V, respectively. Community structure analysis showed low diversity (H': 0.33–0.65) and high dominance (C: up to 0.84), suggesting a community structure dominated by a few species, leading to relatively low stability. Environmental parameters—temperature (30.1–31.7∘ C), salinity (0.50–3.00%), pH (5.45–7.58), and DO (3.77–7.51 mg/L)—were found to influence species distribution. These results confirm that macrozoobenthos is an effective bioindicator for water quality assessment in the Sungai Kakap area. The low community stability implies a need for consistent monitoring to prevent further degradation. Future research should focus on the impact of specific pollutants on these dominant species to support informed mangrove ecosystem management.

Abstract

Penelitian ini menghadirkan inovasi dalam pengelolaan ekosistem mangrove melalui pengembangan WebGIS Mangrove Cerdas 4.0, sebuah sistem digital interaktif yang mengintegrasikan data penginderaan jauh, survei lapangan, dan analisis kualitas air untuk mendukung konservasi pesisir berbasis data spasial. Inovasi ini menjawab kekosongan penerapan teknologi WebGIS yang selama ini belum optimal digunakan dalam pemantauan mangrove di Indonesia. Penelitian dilakukan di Pulau Maya, Kabupaten Kayong Utara, dengan pendekatan kombinatif antara klasifikasi citra Sentinel-2B menggunakan algoritma Support Vector Machine (SVM), analisis Normalized Difference Vegetation Index (NDVI) untuk kerapatan vegetasi, dan interpolasi Inverse Distance Weighting (IDW) untuk parameter kualitas air. Hasil penelitian menunjukkan terdapat 15 jenis mangrove (12 sejati dan 3 asosiasi) dengan dominansi Rhizophora apiculata, R. mucronata, dan Sonneratia alba. Luas kawasan mangrove mencapai 13.871,70 ha dengan akurasi klasifikasi 70,73% (Kappa 0,5579). Berdasarkan NDVI, kerapatan mangrove terbagi atas kategori jarang (490,67 ha), sedang (6.713,92 ha), dan rapat (6.667,11 ha). Parameter kualitas air menunjukkan kondisi yang mendukung pertumbuhan mangrove, yaitu pH 7,0-8,69, DO 3,50-7,99 mg/L, salinitas 11,21-30,49‰, dan suhu 26,6–33,09°C. Seluruh hasil diintegrasikan dalam WebGIS berbasis Leaflet yang dapat diakses publik untuk monitoring konservasi. Penelitian ini menegaskan bahwa integrasi teknologi WebGIS berbasis data spasial dapat menjadi model transformasi digital pengelolaan ekosistem pesisir, sekaligus memberikan kontribusi nyata terhadap konservasi berbasis sains dan partisipasi masyarakat di era 4.0.

Abstract

Kalimantan Barat merupakan wilayah yang memiliki biodiversitas lokal dengan ciri khas alam tersendiri. Beberapa spesies menjadi flora dan fauna identitas daerah, ada yang berpotensi sebagai obat-obatan dan berbagai manfaat lainnya. Pemahaman tentang jenis-jenis dan potensi biodiversitas di Kalimantan Barat masih terbatas di kalangan masyarakat, terutama di kalangan siswa di sekolah. Meskipun para siswa telah mempelajari materi biodiversitas sebelumnya, namun mereka belum memahami konsep biodiversitas tersebut, khususnya biodiversitas lokal yang dimiliki daerah mereka sendiri. Kegiatan pengabdian masyarakat ini bertujuan untuk mengeksplorasi biodiversitas lokal Kalimantan Barat dan mengenalkan platform biologi sebagai media eksplorasi biodiversitas kepada siswa SMAN 1 Sungai Kakap sebagai target kegiatan ini. Penyampaian materi menggunakan Learning Method, yaitu penyampaian materi secara lisan dan dikombinasikan dengan penggunaan poster edukasi. Berdasarkan hasil Pre-Test dan Post-Test, diketahui bahwa pemahaman siswa tersebut meningkat secara signifikan dengan nilai rata-rata 87,96 (Post-Test) dibandingkan sebelumnya 45,93 (Pre-Test). Selain itu, persentase pemahaman siswa terhadap biodiversitas juga meningkat menjadi 92,59% paham dari 62,96% siswa yang tidak tahu tentang biodiversitas. Hal ini menunjukkan bahwa siswa-siswa tersebut telah memahami konsep biodiversitas dan biodiversitas lokal yang dimiliki daerahnya. Platform biologi sebagai media eksplorasi biodiversitas juga membantu siswa dalam memahami spesies, penyebaran dan potensi biodiversitas yang ada di Kalimantan Barat.
