Abstract

Many species of waterbirds depend on wetland sites and related with variated habitats based on the maturity of ecosystems. The objective of this study was to determine the attendance and biodiversity of waterbirds in Rhizophora sp. mangrove stands of varying planting ages in Subang, West Java. Comparisons were made among five stands of different ages in 4 years, 12 years, 21 years, 29 years, and 38 years. Parameters compared were mangrove structure and waterbirds biodiversity. Structure of mangrove was observed in three plots measuring 10 m x 10 m, while waterbirds abundance was doing by bird watching in the three times of test. Results show that mangrove structure differed among stand ages, except in plant cover physiognomy. Average tree height at the youngest stand (4 years) was 1.56±0.33 meters, DBH 2.92±0.23 cm,, and biomass 1.45 kg m-2 ; whereas at the oldest stand (38 years), average height 8.13±5.65 meters, DBH 16.29±7.23 cm, and biomass 108.62 kg m-2. Sixteen species waterbirdss were recorded found in Rhizophora sp. mangrove stands. Six recorded species are listed as endangered in the IUCN Red List. Occurence of waterbirds shows a variety ranged from eight to thirteen species, with the lowest occurrence at the 4 years stand (9.5%) and highest at 29 years (46.2%). The general conclusion is that age (time) affected certain parameters of mangrove structure, but have no effect to waterbirds attendance. Presence of waterbirds also did not show a clear trend or pattern among stands.Keywords: biodiversity, mangrove, Rhizophora, waterbirds.

Abstract

Information about litter decomposition in Rhizophora Sp. mangrove stands of different planting ages is very important to find out the main factors affecting the whole information on structure and function of mangrove ecosystem and to improve mangrove management in the future. The objective of this study was to determine the litter decomposition in Rhizophora sp. mangrove stands of varying planting ages, with a case study in Subang Regency, West Java Province. Comparisons of litter decomposition were taken from five stands of planting ages (4 years, 12 years, 21 years, 29 years, and 38 years old). Four parameters of litter decomposition compared were dry weight of litter, decomposition rate, litter decomposition coefficient, and half-life time. The observation on Rhizophora Sp. mangrove stands was conducted in three plots of 10 m x 10 m. The results show that the litter decomposition parameters, especially dry weight of litter, decomposition rate, litter decomposition coefficient, and half-life time, were different on each planting age of Rhizophora sp. mangrove stands. The fastest time for litter decomposition was found in 12 years old of Rhizophora Sp. stands with the achievement for 90 days of observation and the decomposition efficiency of 100%. Meanwhile, the slowest was found in 38 years old of Rhizophora Sp. mangrove stands with more than 120 days, and the litter decomposition efficiency was about 97.84%. Environmental conditions (soil and water conditions, nitrogen content, and soil fauna) play a major role on its differentiation. It can be concluded that the litter decomposition in Rhizophora sp. mangrove stands of varying planting ages change over time because of the environmental conditions, but the complexity of the relation between ages is not always apparent.

Abstract

Microplastic pollution has become a significant environmental concern, with recent studies detecting microplastics in various ecosystems and natural products, including those produced by bees. This study investigates the presence, morphology, and distribution of microplastics in products of the stingless bee Heterotrigona itama—specifically honey, pollen, and propolis—collected from six meliponiculture sites within the Meratus Geopark, South Kalimantan, Indonesia. Samples were analyzed using stereomicroscopy to identify microplastic types, quantify particles, and measure sizes. The findings reveal that fibers and fragments are the predominant microplastic forms, with urban locations exhibiting higher contamination levels (approximately 309 to 318 particles per 100 ml) compared to rural areas. Notably, one rural site recorded the highest contamination level (approximately 362 particles per 100 ml), suggesting that factors beyond urbanization, such as agricultural practices and atmospheric deposition, contribute to microplastic pollution. The study underscores the role of bees as natural bioindicators for environmental monitoring and highlights the potential risks of microplastic contamination to bee health, food safety, and ecosystem sustainability. These insights are aligned with Sustainable Development Goal 12, which advocates for responsible consumption and production.

Abstract

This study aims to determine the reasons for not using rice straw in the rice field landscape of Mandikapau Barat Village, Banjar Regency. Landscape ecology data extracted from Google Maps. Types, rice production, farmer profiles, and knowledge of rice straw utilization were identified through interviews. The relationship between profile and reasons for not using rice straw was determined by bivariate analysis. Results showed that fragments’ shape is generally elongated (70%) and others hexagonal (30%). The corridor in dry rice fields is 40-50 cm narrow, while in wet rice fields, the embankment width is about 60-80 cm. The average ownership of rainfed rice fields was about ±3,917.6 m2. From nine rice field fragments observed, the average area was ±14,788.4 m2. The most widely grown local rice varieties are Siam Pandak Laut and Siam Cantik. The local rice production rate reached ±2.6 Ton Ha-1, while rice straw production was ±3.6 Ton Ha-1. Most respondents are women (76%), smallholders (80%), and aged 40-50 years (48%). Most respondents (84%) stated rice straw could not be used and had been passed down from generation to generation (64%). There was a relationship between gender and knowledge of straw utilization (p=0.036<0.050) and reasons for not using rice straw (p=0.021<0.050).

Abstract

Satui River is a river that has quite dense activity along the river flow, this is thought to result in a decrease in the quality of river waters. Fish is one of the organisms that can be used in tests to determine some chemical contamination in an aquatic environment. Baung fish are widely found in the waters of the Satui river and baung fish is thought to have properties that are sensitive to environmental changes. Histopathological testing in fish can provide a picture of tissue changes such as the kidneys and liver. Preparation of histological preparations using the paraffin method. Water quality analysis is compared with PP Water Quality Standard No. 22 of 2021 and analyzed using the Pollution Index method. Qualitative histopathological analysis is carried out by descriptive and quantitative analysis using scoring. The conclusion of this study is that the quality of the satui river is classified as lightly polluted with a value of P1 1.11 and P2 2.31. Histopathological damage to the liver of baung fish includes fat degeneration, congestion and necrosis.

Abstract

Background: The expansion of oil palm plantations in Indonesia drives deforestation and biodiversity loss, threatening pollinator communities. Agroforestry systems within oil palm landscapes may enhance floral resources, but their effectiveness is poorly understood. This study evaluates the potential of stingless bee (Heterotrigona itama) pollen analysis as a tool for monitoring floral diversity in different oil palm agroforestry systems. Methods: Pollen samples were collected from H. itama colonies in five distinct oil palm agroforestry systems (block-type, intercropping, row-type, fence-type, and palm oil-livestock) across South Kalimantan. Pollen types were identified microscopically, and diversity metrics (Shannon Index, Simpson Index, and Evenness) were calculated to assess foraging patterns and floral resource availability. Results: Analysis identified 30 plant species from 22 families. Agroforestry type significantly influenced pollen composition. Block-type systems exhibited the highest species richness (14 types), while fence-type systems showed the lowest (9 types) with heavy dominance by maize (Zea mays, 41.4%). Intercropping systems were dominated by Acacia mangium (51.2%). Row-type systems demonstrated the most balanced foraging (highest evenness). A moderate Sørensen similarity index (0.63) between pollen and field vegetation confirmed bees as effective samplers of landscape floral diversity. This research confirms that H. itama pollen analysis is an efficient bioindicator tool, revealing that agroforestry management directly shapes pollinator resource availability. Complex systems (e.g., block-type, row-type) support higher floral diversity, which is crucial for pollinator conservation and sustainable productivity in oil palm-dominated landscapes. This method provides a practical approach for guiding biodiversity-inclusive agricultural practices.
