Abstract. Siddiq AM, Wimbaningrum R, Sulistiyowati H, Setiawan R, Setiawan A, Wahono ND. 2024. Short Communication: A rapid survey of herpetofauna diversity in Bama coastal forest at Baluran National Park, Indonesia. Biodiversitas 25: 2323-2329. Scientific reports on herpetofauna in Baluran National Park (BNP) are still limited. Meanwhile, several geographical areas, such as the Bama Baluran National Park coastal forest, have potential herpetofauna diversity within this conservation area yet to be reported. Therefore, this study aimed to determine the diversity of herpetofauna species in BNP's Bama coastal forest (BCF). The method was conducted using the Visual Encounter Survey (VES) in three tracks, conducted by combining Time Restricted Search (TRS) or using observation time for five hours during the mid-afternoon (06.00 AM-11.00 AM) and four hours at night (07.00 PM-11.00 PM) on each track. This study recorded 17 herpetofauna species, comprising 6 amphibian and 11 reptile species, in the BCF of Baluran National Park. The diversity index of herpetofauna species in this area was moderate category (H’=2.25). Species Fejervarya limnocharis Gravenhorst 1829 (38 individuals) has the highest abundance in the BCF and was found in track 1 (swamp area). Meanwhile, three species have the lowest abundance, such as Kaloula baleata Müller 1836, Microhyla palmipes Boulenger 1897, and Cryptoblepharus balinensis Barbour 1911, with 1 individual in each species.

Abstract. Siddiq AM, Kurnianto AS, Sulistiyowati H, Wijaya MT, Ratnasari T, Dewi N, Utami ET, Ayuningtyas TR. 2024. Wildlife existence and potential threats in Pelangi Forest Biosite of Ijen Geopark, East Java, Indonesia. Biodiversitas 25: 4487-4497. A comprehensive study of the diverse wildlife and potential threats at the Pelangi Forest Biosite (Rainbow Forest Biosite, RFB) of Ijen Geopark, East Java, Indonesia was conducted in May 2023. Bird and primate observations were carried out using the point count method, while herpetofauna observation was conducted using the Visual Encounter Survey (VES). Data collection on potential threats to community activities in the RFB used a questionnaire survey method. Data analysis used the Diversity Index (H’), Existence factor (Ef), and scale-Likert for potential threats. The Pelangi Forest is home to an impressive 62 wildlife species, including six amphibian species, nine reptile species, 46 bird species, and one primate species. The value of wildlife species diversity in RFB, calculated using the Shannon-Wiener index, is remarkably high (H= 3.48). The wildlife species in the Pelangi Forest had an average existence value of 41.94%, indicating a moderate uniqueness level, with the Javan lutung (Trachypithecus auratus (É.Geoffroy Saint-Hilaire, 1812)) standing out with the highest Ef value (80%). According to Likert-scale analysis, potential threats to biodiversity in the RFB of Ijen Geopark are relatively low (23.54%). However, some crucial notes for evaluating the conservation plan, namely the illegal poaching or hunting of wildlife species, such as birds and large mammals, still occur. Therefore, implementing education-based tourism, such as birdwatching or wildlife observation, can increase awareness and knowledge about conservation for tourists and society.

Abstract. Sulistiyowati H, Setiawan R, Siddiq AM, Wimbaningrum R, Afriyanto M, Hasanah EA, Mulyadi BP, Baraas A. 2025. Ecological insights post-restoration from two decades of mangrove forest succession in Pangpang Bay, East Java, Indonesia. Biodiversitas 26: 2299-2308. The Mangrove Pangpang Bay (MPB) in Banyuwangi District, East Java, Indonesia, has suffered significant degradation from anthropogenic pressures. A restoration project was launched in the late 1990s, and between 2000 and 2003, approximately 300,000 trees were planted across 70 ha. However, 22 years later, little is known about the structural and functional dynamics of the mangrove forest's succession. This study assesses the structural complexity, ecological functionality, and environmental resilience of the restored mangrove forest in MPB. Tree vegetation data were collected using 10x10 m² plots, and functional data were obtained through a semi-destructive method. Secondary data on species conservation status and geographic distribution were sourced from the IUCN Red List, while abiotic factors, including temperature, pH, and salinity, characterized environmental conditions. The MPB comprises 11 mangrove species from 5 families and 7 genera, dominated by Rhizophora mucronata and Sonneratia alba. Abiotic conditions, salinity (31.85%), soil pH (7.96), and temperature (29.89?) are favorable for mangrove growth, particularly for the Rhizophora. The Shannon-Wiener Diversity Index (H') was low (0.98), indicating secondary succession influenced by human-led planting. Mangrove tree density averaged 3,719 trees/ha, with 1,392 seedlings/ha, and vegetation volume was 18,556.10 m3/ha. The estimated carbon stock was 104.58 Mg C/ha, equating to 383.49 Mg CO2/ha and 277.42 Mg O2/ha. Salinity correlated positively with carbon stock and tree volume, while pH, temperature, and diversity showed negative correlations, indicating potential trade-offs in shaping the restored ecosystem of MPB. Additionally, the total biodiversity value of MPB was calculated to be 9,733,952,191.99 IDR per hectare.

Abstract

Jember Regency encompasses several plantation areas characterized by diverse ecological conditions, notably the Gumitir, Garahan, and Tancak plantations. Among the flora in these regions, the genus Hoya is notable for its medicinal potential. This study aimed to characterize the diversity of Hoya species, provide detailed morphological documentation, and evaluate the phytochemical and antioxidant properties of a medicinally used species. Field exploration employed a systematic plot-based design consisting of 150 plots (5 × 5 m²) with 3 m spacing. The most vegetatively dominant species, Hoya lacunosa, was subjected to GC–MS phytochemical analysis and DPPH-based antioxidant evaluation. A total of eleven Hoya species were recorded across the three plantation sites. The Gumitir plantation exhibited the highest diversity, containing ten species., i.e. Hoya burtoniae, H. camphorifolia, H. carnosa, H. cinnamomifolia, H. dennisii, H. fuscomarginata, H. lacunosa, H. micrantha, H. purpureofusca, and two unidentified Hoya spp. In contrast, the Garahan plantation supported only H. dennisii and H. fuscomarginata, while H. lacunosa was exclusively found in Tancak indicating a highly localized distribution. GC-MS profiling on H. lacunosa leaves revealed 26 compounds, comprising 16 secondary metabolites (12 phenolics, 2 alkaloids, and 2 terpenes) and 5 primary metabolites. The methanol extract exhibited strong antioxidant activity (IC₅₀ = 50.89 ppm), reflecting its potential as a natural source of bioactive compounds. These findings demonstrate substantial Hoya diversity in Jember Regency and underscore the potential of H. lacunosa as a valuable source of bioactive metabolites for pharmaceutical development.
