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

Penelitian ini menganalisis struktur koloni dan bentuk sarang lebah kelulutHeterotrigona itama untuk mendukung praktik meliponikultur berkelanjutan di Desa PadangPanjang, Kabupaten Banjar. Sampel lebah diambil dari kebun karet dan cempedak kemudiandiawetkan. Struktur koloni dianalisis berdasarkan parameter warna, sifat fisik, jumlah koloni,serta aktivitas keluar masuk sarang. Pengamatan dilakukan pukul 10.00–11.00. Aktivitas keluarmasuk lebah banyak didapati di kebun cempedak. Pintu masuk berbentuk corong di kebun karetdengan diameter ±3,1 cm lebih besar dibandingkan di kebun cempedak sekitar ±0,6 cm. Rata-ratapanjang corong di kebun karet adalah ±4,3 cm, lebih panjang dibandingkan di kebun cempedak±2,6 cm. Warna corong umumnya kuning kecoklatan 60% di kebun cempedak. Jumlah pot madudi kebun karet sebanyak ±25 pot, lebih banyak dibandingkan kebun cempedak. Volume pot madudi kebun karet ±4,1 ml/pot, lebih sedikit dibanding kebun cempedak. Volume log berbentuksilinder di kebun karet ±7,8 liter, lebih rendah dibandingkan di kebun cempedak. Rata-rata volume ukuran topping adalah ±11,2 liter di kebun karet, lebih besar dibanding di kebun cempedak. Rata-rata jarak sarang dari sumber air di kebun karet 10,4 m lebih jauh dibanding kebun cempedak sekitar ±9,4 m.

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.
