Abstract. Riefani MK, Soendjoto MA. 2021. Birds in the west coast of South Kalimantan, Indonesia. Biodiversitas 22: 278-287. There is no comprehensive data on birds in the west coast of South Kalimantan, yet the areas are pressured by human activities, especially the rapidly growing tourism. This study aimed to investigate the diversity of bird species that occurred in the west coast of South Kalimantan and to compare the similarities of bird communities across four villages used as the sampling sites, i.e. Sungai Rasau, Sungai Bakau, Tabanio, and Pagatan Besar. Transect method combined with concentration count method were used to record diurnal bird species and number of individuals in five replications from April to September 2020. The observation area was 100 m from the shoreline toward the sea and 400 m from the shoreline toward the inland along 2 km with observation time was 07.00-11.00 and 16.00-19.00. Shannon Wienner species diversity index (H'), a Dice community similarity index based on the presence or absence of species (ISD), and a community similarity index (modification) based on the number of individuals per species (ISM) were analyzed. In total, there are 101 bird species recorded belonging to 41 families with Sungai Bakau Village has the highest number of species (81 species), while Pagatan Besar Village is the lowest (62 species). Thirty-four species are categorized as waterbirds. Twenty-three species are categorized as migratory birds. In terms of diversity index from highest to lowest are Sungai Bakau (4.04), Sungai Rasau (3.95), Pagatan Besar (3.65), and Tabanio (3.48). The similarity of the ISD community ranges from 0.74-0.84, while the ISM ranges from 0.73-0.90. One case (Sungai Bakau - Tabanio) shows that community similarity based on the number of individuals per species is smaller than based on the presence or absence of species. Based on the protection status following Indonesian government regulation, most (84.16%) birds are categorized as unprotected, while based on the conservation status of IUCN, the majority (91.09%) are Least Concern. The results of this study can be used as baseline information for sustainable management of the area in various aspects, including future research (such as on pest and disease control), tourism (such as bird watching), and education (such as field guide).

Zooplankton has an important role in waters, especially in the food chain, these organisms are consumers I which play a major role in bridging energy transfer from major producers (phytoplankton) to living things at higher trophic levels (fish and shrimp). This study aims to analyze the relationship between zooplankton abundance with phytoplankton and physicochemical parameters in the waters of Kastela, Ternate. The research was conducted from March to April 2017 in the waters of Kastela Ternate City North Maluku Province at 5 stations and 4 periods of sampling. Zooplankton samples were taken by filtering methods. The results showed that there were 20 zooplankton genera from 5 (five) classes namely Ciliate (4 genera), Crustaceae (8 genera), Hydrozoa (3 genera), Rotifera (3 genera), and Urocohordata (2 genera). Zooplankton abundance ranges from 1032 to 10942 cells.l-1, the highest at station 3 periods II (10942 cells.l-1), and the lowest at station 4 period I (1032 cells l-1). The range of values of the zooplankton biological indices is diversity index (0.5005 - 1.8662), uniformity index (0.6521 - 0.9601), and dominance index (0.1661 - 0, 6800). There was a low correlation between zooplankton abundance and phytoplankton abundance and physical-chemical parameters of water in Kastela waters, with determination coefficient is 0.236 and regression equation Y = 35079.107 + 0.030 phytoplankton - 791,251 temperature + 75,417 salinity - 1658,557 pH Keywords: mangroves, macrozoobenthics, organic matter

Abstract. Tambaru R, Burhanuddin AI, Massinai A, Amran MA. 2021. Detection of marine microalgae (phytoplankton) quality to support seafood health: a case study on the west coast of South Sulawesi, Indonesia. Biodiversitas 22: 5179- 5186. The research aimed to detect marine microalgae quality to support seafood health was carried out from January to November 2020 along the west coast of South Sulawesi, Indonesia. Samples were collected from the coastal waters of Pangkep District, Maros District, and the northern part of Makassar City. Phytoplankton cell counts were obtained using the deposition method developed by Uthermol. Phytoplankton cell abundances were calculated through sweeping (census) using a Sedgwick Rafter Cell (SRC). Two-way analysis of variance (ANOVA) was used to compare the distribution of marine microalgae community abundance between observation stations and periods. Based on the types and relative abundance of phytoplankton present, i.e., harmful algal bloom (HAB) forming or not (non-HAB), the results showed the quality of marine microalgae, specifically, phytoplankton was relatively good. Many more non-HAB (94-98%) than HAB (2-6%) marine microalgae were detected. Thus, the phytoplankton flourishing in these waters is mostly suitable as food for other organisms, including fish and shellfish. This also means that if fishers harvest these fish and shellfish, they should be fit and safe for human consumption.

The Citarum River is the longest river in West Java Province which is used for various human activities to produce a load of waste input into water bodies which cause changes in the physical and chemical parameters of the waters that will affect the life of aquatic organisms that live in it, one of which is zooplankton. Zooplankton can be used as a water bioindicator because it has a high level of sensitivity to pollution, especially in freshwater. The purpose of this research is to determine the physical-chemical quality of the water in the Citarum River and its influence on the structure of the zooplankton community in this environment. The research was carried out from August 2020 until October 2020 with a purposive sampling method. Sampling was carried out at 5 stations with 6 repetitions every 1 week. The parameters observed were physical and chemical parameters of the waters, an abundance of zooplankton, diversity index, and dominance index. The results showed that the composition of zooplankton in the Upstream Citarum River was 15 genus consisting of 2 phyla. The abundance of zooplankton obtained ranged from 21 - 51 individuals/L. The Simpson diversity index (D) obtained a range between 0.59 - 0.73 for the high category. The dominance index obtained ranges from 0.27 to 0.41 for the low category. Dissolved oxygen and pH are the parameters that most influence the presence of most of the identified zooplankton orders.
