Abstract. Zayadi H, Hakim L, Sudarto, Batoro J. 2024. Plant diversity on coffee agroforestry land in the buffer zone of Bromo Tengger Semeru National Park in East Java, Indonesia. Biodiversitas 25: 1030-1036. Bromo Tengger Semeru National Park (BTSNP) is facing threats to biodiversity due to land transfer functions and sand mining in rural areas. Land use conversion and sand mining in rural areas near BTSNP and Perhutani are threatening biodiversity through activities like land degradation, deforestation, forest depletion, and global climate change impacting local agriculture. Coffee farms in Poncokusumo and Wajak have been abandoned, leading to a decline in coffee farming and other agricultural commodities. Coffee-based agroforestry systems have been implemented to address this issue and improve soil fertility and vegetation diversity. This research aimed to identify and analyze plant diversity in coffee agroforestry land in BTNSP. The study was carried out in January-December 2022 in the village districts of Poncokusumo Sub-district (Sumberejo) and Wajak Sub-district of Malang District, which borders directly with BTSNP, collecting flora compositions and classifying them based on growth rate. The study identified 27 orders, 38 families, and 71 species of plants in the coffee fields. The presence of various plant species in the coffee fields contributes to the ecosystem's stability and the soil's quality. This research highlights the importance of the agroforestry system in promoting biodiversity conservation and sustainable coffee farming in the BTSNP area.

Abstract. Oetama D, Hakim L, Lelono TD, Musa M. 2024. Health status of coral reef at Moramo Bay Marine Conservation Area, Southeast Sulawesi, Indonesia. Biodiversitas 25: 1454-1464. Moramo Bay is one of the regional Marine Conservation Areas (MCA) in Indonesia which is categorized as a Marine Tourism Park based on the Decree of the Minister of Maritime Affairs and Fisheries of the Republic of Indonesia Number 22 of 2021. This bay is located in Southeast Sulawesi Province and has an area of 21,902.34 ha, consisting of a core zone, limited-use zone, and other zones. The ecosystems found in Moramo Bay include coral reefs, mangroves, and seagrass. The coral reef ecosystem in this area covers 2,528.19 ha with good visual conditions of the reef. The present study aims to provide detailed information concerning the condition of live hard corals and reef fishes, including abundance, diversity, evenness, dominance, and water quality by using point intercept transect (PIT) and underwater visual census (UVC) methods. The study was carried out at 7-10 meters of seawater depth in May-October 2023, focusing on both the core and limited-use zones and consisting of three study stages: field observation, data collection, and data analysis. Data collection covered identifying coral growth through literature study before performing descriptive analysis. The study revealed the percentage of live hard coral cover of 53%, referred to as a good category, and other variable percentages including dead coral (4%), dead coral with algae (9%), soft coral (4%), fleshy seaweed (1%), rubble (17%), sand (8%), silt (1% ) and sponge (2%). Furthermore, 25 families of reef fishes were found, belonging to 48 genera, 102 species, and 2,364 individuals, with an ecological index of abundance of 1.05 ind.m-2, diversity (2.86), evenness (0.83), and dominance (0.10). The coral reef health data issued by the present study implies that Moramo Bay MCA may be preserved as an alternative area for coral reef studies associated with global issues, for instance, climate changes. Protecting and increasing the sustainability of coral reefs is an absolute entity that must be considered by a local government.

Abstract. Habibah LN, Hakim L, Pangestuti E, Siswanto D, Rahardi B. 2024. Vegetation diversity, structure and composition in nature-based recreation sites as a potential tourist attraction in Banyuwangi, Indonesia. Biodiversitas 25: 3273-3285. The presence of vegetation in nature-based tourism sites plays an important role in adding natural scenic beauty and creating comfortable local climates. However, the potential of vegetation in the recreation landscape for conservation and educational aspects is less studied. This research aims to identify vegetation diversity, structure and composition of plant species in nature-based tourism recreation sites in Banyuwangi District, East Java. Vegetation survey was conducted at 16 recreation sites, ranging from coastal to lower mountain ecosystems with varying management types from national parks, state and privately owned enterprises and community-private ownerships. Research shows that recreation sites contain diverse plant species that can support nature-based tourism attractions. The recreation sites in the national parks harbor native vegetation in, which it is important for biodiversity education through nature-based tourism programs. Fewer exotic plant species are found in nature-based recreation sites, especially in conservation areas. Conversely, nature-based recreation sites managed by community and private are dominated by exotic plant species. The existence of exotic plant species in nature-based recreation sites can add economic value by providing agrotourism activities, yet it requires special attention to protect the native habitats in those sites.

Abstract. Ihwan, Arumningtyas EL, Retnaningdyah C, Hakim L. 2024. Phylogenetic analysis of Rhizophora mucronata in Savu Sea Marine National Park, East Nusa Tenggara, Indonesia. Biodiversitas 25: 4498-4506. Mangroves, a crucial coastal ecosystem, play a crucial role in marine biodiversity and shoreline protection. This study investigates the phylogenetic patterns and haplotype analysis of Rhizophora mucronate, a key mangrove species, in the biodiverse Savu Sea Marine National Park within the Coral Triangle. We collected 30 R. mucronata samples from 15 mangrove populations in the park, including Sumba Island, Sabu Island, Rote Island, and Timor Island. The Maximum Likelihood-based phylogenetic tree reconstruction revealed distinct genetic clusters, segregating populations into two primary clades: Indo-West Pacific (IWP) and Atlantic East Pacific (AEP). Populations from the Sumba, Rote, Semau, Timor, and Sabu Islands primarily aligned with the IWP clade, while some samples exhibited unexpected clustering patterns, indicating potential unique genetic lineages. Notably, populations from Hambapraing and Tesabela showed closer genetic affinity to AEP and the outgroup species, respectively. Our subsequent haplotype analysis further unveiled a complex network of sequence-dependent populations, with notable haplotypes, such as Haplotype 2, showing widespread distribution across Sabu, Sumba, Rote, and Timor, and Haplotype 13 linking populations from Singapore, China, India, USA, Kenya, and Seychelles. These findings not only underscore the complexity of genetics but also highlight the importance of considering distinctive genetic patterns to unravel evolutionary relationships, thereby providing a solid foundation for future research and conservation initiatives.

Abstract. Abdullah M, Hakim L, Siswanto D, Setyowati DL. 2024. Mountain tourism impact on bird diversity along hiking trails of Mount Prau, Central Java, Indonesia. Biodiversitas 25: 4690-4698. Hiking represents a significant dimension of mountain tourism and has gained considerable popularity among travelers. Unfortunately, the perception of hiking activities as a form of mass tourism raises significant concerns regarding potential environmental degradation and the threats posed to biodiversity in mountainous regions. Birds are organisms that are sensitive to human activities. Therefore, a critical component for assessing the impact of mountain tourism on biodiversity is to analyze the diversity of bird species on several hiking trails. This study aims to examine the differences in bird species diversity on several hiking trails with different visitor frequencies on Mount Prau, Indonesia. Surveys for bird observations were conducted systematically using the Variable Circular Plot (VCP) method along the hiking trail. Bird species diversity data were analyzed to obtain Margalef's species richness index, Shannon diversity index, and Pielou's evenness index. In addition, correspondence analysis was also used to see the differences in the composition of bird community species on different hiking trails. Trails with high visitor preferences showed lower species richness, diversity, and evenness indices than rarely visited trails. Ordination analysis showed a clear grouping of bird communities based on species composition between highly visited and less visited routes. Less frequented Mount Prau trails host diverse endemics and high conservation status birds, while heavily frequented trails show reduced diversity. This finding confirms the negative impact of mountain tourism on bird biodiversity in the mountain area. This also signifies the need for a conservation strategy to balance mountain tourism with biodiversity conservation in Mount Prau. It should be able to limit the number of visitors, control access in sensitive areas, and involve methods of ecotourism that would favor wildlife.

Abstract. Sianipar HF, Widoretno W, Hakim L, Amolia RR, Fatchiyah F. 2024. Phytochemicals’ compound and antioxidant activities in the food of Pongo tapanuliensis from Batang Toru Forest, North Sumatra, Indonesia. Biodiversitas 25: 3454-3463. Campnosperma auriculatum (Blume) Hook.fil. and Agathis borneensis Warb. are food for Pongo tapanuliensis Nurcahyo, Meijaard, Nowak, Fredriksson & Groves, 2017 found in the Batang Toru Forest, Indonesia. Studying the phytochemical properties of both plant species is important part of conservation framework for Tapanuli orangutans because information regarding their nutrient contents and benefits still needs to be investigated. This research examined the closest components, amino acids, and phytochemicals compounds that have antioxidant activity. The C. auriculatum and A. borneensis fruit were tested for proximate, amino acid, phytochemical, total flavonoid content, LC-MS/MS, and FRAP to determine antioxidant activity. The results of proximate and amino acid tests showed that C. auriculatum has higher contents of carbohydrates (74.49%), protein (7.54%), lipids (3.73%), energy from fat (33.57Kcal/100 g), total energy (361.71Kcal /100g), L-Histidine (1704.975ppm), L-Leucine (3759.28ppm), and L-Lysine (2099.038ppm) compared to A. borneensis. The phytochemical tests of both samples were positive for containing alkaloids, flavonoids, saponins, steroids, tannins, phenolics, and quinolines. The higher flavonoid content is found in C. auriculatum (94.44±2.77mg QE/g). LC-MS/MS results for both samples, C. auriculatum that is (3alpha,20R,24Z)-3-Hydroxy-21-oxoeupha-8,24-dien-26-oic acid, terpenoid group, and A. borneensis, that is Procyanidin B2, the flavonoid group. The higher antioxidant capacity was found in C. auriculatum (4.63±0.111µg/mL). The C. auriculatum has excellent potential as a natural source of nutrition and antioxidants for the Tapanuli orangutan; therefore, it is necessary to develop a strategy by cultivating these two plants and using them in pharmacognosy for P. tapanuliensis.

Abstract. Retnaningdyah C, Hakim L, Arisoesilaningsih E, Sumani, Setiahadi R, Mukhtasor. 2025. Phytoplankton diversity as a health indicator of coastal ecosystems in Prigi Bay, Trenggalek District, East Java, Indonesia. Biodiversitas 26: 2198-2209. This study aims to evaluate the water quality of several coastal ecosystems in the Prigi Bay, Watulimo Sub-district, Trenggalek District, East Java, Indonesia, based on water physicochemical parameters and phytoplankton diversity as bioindicators. Water and plankton sampling were conducted in six coastal ecosystems (Beach of Pasir Putih, Karanggongso, Mutiara, Guo Boto, Prigi, and Karang Pegat). The water physicochemical parameters evaluated include DO, TSS, turbidity, salinity, pH, conductivity, BOD, nitrate, orthophosphate, H2S, and oil-grease. A total of 10 L of water was filtered with a plankton net. Then, the phytoplankton species were identified, and the abundance of each type was calculated. The data obtained were used to determine taxa richness, total density, evenness, dominance index, diversity index, Trophic Diatom Index (TDI), and Percentage Pollution Tolerant Value (%PTV). The study results showed that the physical-chemical quality of water in all research areas met the national and international quality standards concerning seawater quality standards for marine biota, except nitrate, orthophosphate, and oil-grease. A total of 40 species were found in the six coastal ecosystems in the Watulimo area. The abundance of phytoplankton from the Bacillariophyceae was always the highest in all locations, ranging from 67-78%. Phytoplankton diversity is relatively high (4.38-4.84). There is no species dominance or even distribution. The quality of water in coastal ecosystems in the Watulimo area, based on the TDI, is classified as eutrophic. Based on %PTV, there is no indication of organic material pollution except for the Prigi Beach ecosystem, which is included in the lightly polluted organic material category. High human activities around Prigi Beach have impacted the increasing turbidity and orthophosphate content, resulting in high levels of eutrophication and organic material pollution, as indicated by an increase in %PTV and TDI values.

Abstract. Andrimida A, Hakim L, Retnaningdyah C. 2025. New records and updated checklist of heterobranch sea slug (Gastropoda: Heterobranchia) from South Malang, Indonesia. Biodiversitas 26: 3674-3693. This article presents an integrated and updated checklist of heterobranch sea slug species from South Malang, East Java, Indonesia, based on additional records from recent surveys, published records and citizen scientist findings since 2019. A different approach to survey method was conducted during this study, where surveys were done by exploring shallow tidepools in contrast to previous studies in South Malang that followed SCUBA diving-based survey. Twelve surveys have been conducted at three new localities in South Malang from September 2024 to March 2025. A total of 14 new species has been successfully documented as new locality records from three main sites, which are Banyu Towo, Tanjung Penyu, and Gatra. These 14 species assigned to the Aplysiida order (two species), Sacoglossa superorder (three species), Pleurobranchida order (three species) and Nudibranchia order (six species). With this finding, combined with previous studies, a total of 79 heterobranch sea slug species has been recorded from South Malang, which 57 species belong to the Nudibranchia order, nine species belong to the Aplysiid order, eight species belong to the Sacoglossa superorder, three species belong to the Pleurobranchida order, and two species belong to the Cephalaspidea order were found. This study also provides nine species corrections from past studies following taxonomical update or possible misidentification in the past. Compared to other records, it is revealed that heterobranch sea slug species diversity in South Malang is higher than the average heterobranch sea slug species diversity in Java Region. Higher heterobranch sea slug diversity indicates diverse habitat structure and higher overall diversity in coral reef ecosystem. This study provides baseline data for future monitoring programs, as there is a rising anthropogenic pressures from the nearby fishing port activities and forest conversion that causes sedimentation and threatens the coral reef health in Sempu Island, East Java. Furthermore, this extended checklist significantly enhances marine biodiversity records by filling knowledge gaps from understudied area in South Malang, thereby strengthening the data basis that is necessary for future coastal ecosystem monitoring and conservation in South Java Region.

Abstract. Hakim L, Yusuf M, Wiratantra FD, Rahardi B, Sunarharum WB, Nurrofik A. 2026. Tree diversity, structure and composition in coffee agroforestry with varying shade systems, coffee species, and landscape settings in Malang, Indonesia. Biodiversitas 27 (5): d270509. https://doi.org/10.13057/biodiv/d270509. Coffee agroforestry in Malang Region, East Java, Indonesia has been widely recognized as a multifunctional land-use system that integrates economic, and social benefits; however, its comprehensive ecological characteristics remain poorly documented. This study examines tree diversity and ecological indicators in coffee agroforestry systems in Malang, East Java, across four landscape settings, three coffee species (arabica, robusta, and liberica) and shade systems typology (shaded monoculture, commercial polyculture, traditional polyculture and rustic). Field surveys were conducted at 64 sites to document shade-tree diversity, composition (Important Value Index) and ecological indices (Shannon-Wiener Diversity Index (H′), Evenness Index (E), and Simpson Dominance Index (D′)). In total, there were 40 species of shade trees across all sites and primarily composed of Fabaceae and Malvaceae which contribute to soil fertility, habitat provision, and raw material resources. Results indicated that among shaded systems in averages includes, rustic-type exhibited the highest tree species diversity, high evenness, and low dominance (H′ = 2.02, E = 0.97, D = 0.19), followed by traditional polyculture systems (H′ = 1.23, E = 0.91, and D = 0.3), commercial polyculture (H′ = 0.8, E = 0.89, D = 0.46), and shaded monoculture (H′ = 0.17, E = 0.29, and D = 0.83). Liberica coffee agroforestry tended to show higher diversity index of shade trees with less dominance of few species compared to the other two. However, although its diversity assessments belong low to moderate scores, the presence of shade tree diversity has been shown to have a practical impact on the dynamics of coffee agroforestry, allowing farmers to increase food security while generating additional income beyond coffee. Therefore, to support ecological sustainability and community well-being in the Malang Region, conservation strategies and policy frameworks should prioritize biodiversity-friendly agroforestry management.

Abstract. Faronny DI, Rahma MJ, Nugroho BBA, Soemarno, Sunarharum WB, Hakim L, Batoro J. 2026. Vegetation structure and diversity of liberoid coffee agroforestry (Coffea liberica and Coffea dewevrei) across contrasting ecosystems in Indonesia. Biodiversitas 27 (5): d270536. https://doi.org/10.13057/biodiv/d270536. Climate change is projected to substantially reduce the climatically suitable range of Coffea arabica and Coffea canephora by 2050, elevating the strategic importance of the liberoid coffee group, comprising Coffea liberica and Coffea dewevrei, as climate-adaptive alternatives. This study characterized vegetation structure and associated species diversity of liberoid coffee agroforestry across three contrasting ecosystems in Indonesia: volcanic mountain agroforestry (Wonosalam, East Java), coastal agroforestry (South Malang, East Java), and tropical peatland agroforestry (Tanjung Jabung Barat, Jambi). Using nested quadrat sampling (18 plots; 400 m² each), vegetation data were analyzed through Importance Value Index (IVI) and Shannon-Wiener diversity indices (H'), vertical and horizontal canopy profiling, and NMDS ordination with Bray-Curtis dissimilarity. A total of 893 individuals representing 40 species from 23 families were recorded. C. dewevrei dominated mineral-soil systems in Wonosalam and South Malang, while C. liberica was the exclusive Coffea taxon in the Jambi peatland. Shannon diversity ranged from H': 0.72 to 2.13, with the highest mean diversity recorded at South Malang (H': 1.63); this gradient does not follow the pattern expected from ecosystem productivity alone, but rather a pattern in which farmer management decisions are a contributing factor, though management variables were not directly measured. NMDS ordination (stress: 0.029) revealed near-complete floristic separation of peatland communities from mineral-soil sites (Bray-Curtis: 0.93-0.94), reflecting ecosystem-level divergence under extreme organosol conditions. Musa paradisiaca and Leucaena leucocephala were identified as cross-ecosystem companion species in mineral-soil systems. These studies provide an observational framework for ecosystem-differentiated supporting climate-adaptive liberoid coffee cultivation, contingent on expanded replication and direct environmental monitoring.
