Abstract

ABSTRAKKima (Giant clam) merupakan kelompok kerang laut yang termasuk dalam anggota Famili Cardiidae dan Kelas Bivalvia. Kima merupakan salah satu komoditas perdagangan internasional yang bernilai ekonomis tinggi. Kondisi habitat Kima yang heterogen sangat menarik untuk diteliti, terutama dalam rangka memahami karakteristik habitat dan keanekaragaman spesies kerang kima di zona intertidal Pantai Bilik Taman Nasional Baluran. Untuk menentukan karakteristik habitat  yang dipilih populasi kerang kima dan keanekaramanan spesies, dilakukan metode road sampling dengan cara ‘tracking’ pada tipe-tipe habitat dan analisis karakteristik habitat mengggunakan klasifikasi analisis substrat karang laut. Karakteristik habitat yang paling disukai kerang kima adalah RCK (rocks) dengan prosentase 64.28% dan yang terendah S (sand) dengan prosentase 3.57 %. Keanekaragaman spesies kerang kima di zona intertidal pantai Bilik TNB tergolong rendah, sejumlah 4 spesies yang ditemukan yaitu Tridacna crocea, T. maxima, T. squamosa dan Hippopus hippopus. Nilai kemerataan menunjukkan hasil yang mendekati nol yang berarti ada spesies yang mendominasi dalam komunitas kerang kima yaitu spesies T. crocea yang jumlahnya mencapai 38 individu.Kata Kunci: Kima, Tanjung Bilik, Taman Nasional BaluranABSTRACTKima (Giant clam) is a group of sea shells that belongs to the cardiidae family and the Bivalvia class. Kima is one of the international trade commodities with high economic value. This heterogeneous habitat condition is interesting to study, especially in order to understand the habitat characteristics and species diversity of clams in the intertidal zone of the Baluran National Park chambers. To determine the characteristics of the habitat selected by the clam shell population and species diversity, a road sampling method was carried out by 'tracking' the habitat types and the Habitat characteristics analysis using coral reef classification. The most preferred habitat characteristics for clams are RCK (rocks) with a percentage of 64.28% and the lowest is S (sand) with a percentage of 3.57%. The diversity of species of clams in the intertidal zone of Bilik TNB beach is low, numbers 4 species were found, namely Tridacna crocea, T. maxima, T. squamosa and Hippopus hippopus. The evenness value shows a result that is close to zero, which means that there are species that dominate in the clam shell community, namely T. crocea, which number reaches 38 individuals.Keywords: Kima, Bilik Capet, Baluran National Park

Abstract

Bilik beach Baluran National Park (TNB) is dominated by mangrove forest and one type of mangrove found was Rhizophora apiculata Blume. So far there has been no information about the distribution pattern of R. apiculata Blume in mangrove forest of Bilik beach TNB. This distribution pattern is very needed as a source of information in the managing and preserving the mangrove forest conservation areas. The method was done by collecting data of R. apiculata Blume and the abiotic environmental factors. It was done in 10x10 m2 plot. The data of R. apiculata Blume that has been recorded included the number of trees, circumference of the stem, position of tree coordinates, and some parts of the R. apiculata Blume plant. The data were analyzed using the the Standardized Morisita Index value and ArcGIS 10.1 software. . There has been found 147 trees that control a space of 3.19 m2 in the area of 10.600 m2. The distribution pattern of R. apiculata Blume in coastal mangrove forests in Bilik TNB grouped based on the value of the Standard Morisita Index (Ip) which is more than zero. It is supported by the spatial map obtained from the ArcGIS 10.1 digitization that shows 66,6 % of R. apiculata Blume presence grows close to one and another. The clustered distribution pattern is caused by the stilt-root characteristics and morphological structure of the reproductive organs R. apiculata Blume.

Abstract

The research aimed to monitor surface water quality by using water quality index NSF-WQI and accurate biotic index of benthic macroinvertebrate. This study was conducted in September to November 2012 in some water tourism destinations in three regencies, i.e. Jember (three sites), Pasuruan (one site), and Malang (one site), East Java, Indonesia. Each site consisted of three stations (upstream, middlestream and downstream). Reference upstream and middlestream were located in the Meru Betiri National Park (MBNP) Jember. Water quality and benthic macroinvertebrates sampling were conducted in each site. While physical-chemical data consisted of TDS, DO, pH, NO3-N, TP and temperature were analyzed to determine the NSF-WQI index. Macrozoobenthic data were analyzed to determine three diversity indices and 11 biotic indices. Results showed that based on parameter of DO, TP, NO3-N, TDS and pH, water quality in downstreams were generally lower than upstreams. Upstream to middlestreams of two sites in Jember were good to excellent based on NSF-WQI water quality and biotic indices. Therefore, the water were qualified as drinking water resources and also served as safe recreational water. The accurate biotic indices to surface water quality in this study were % EPT, ASPT, HBI, FBI and % Gastropodes.Keywords: biotic indices, benthic macroinvertebrates, water quality index, water tourisms destination

Abstract

One of the primate species found in the Watangan Puger Nature Reserve is the Javan langur (Trachypitecus auraus). The IUCN Redlist classified this primate as vulnerable and it is included in CITES Appendix II. The aim of this study was to determine the distribution pattern of the Javan langur population in the Watangan Puger Nature Reserve. The data was collected from February to April 2021. A combination of concentrated method (Concentration Count) and ad libitum observation method was employed to obtain data. Analysis of the population distribution pattern was carried out using the Nearest Neighbor, while the population distribution was analyzed using the area of the outermost point of encounter. Both analyzes were performed using ArcGIS software version 10.1 and QGIS version 3.18. There are two distinct groups. In the first group, there were 17 individuals with a population density of 6.54 ind/km2, while in the second group were 9 individuals with a population density of 3.46 ind/km2. The distribution pattern of the population is classified as clustered in all groups with p-value and z-score of 0.000306 and-3.610344 for the first group and 0.000169 and-3.760636 for the second group respectively. The population distribution of Javan langurs in the Watangan Puger Nature Reserve covers about 43% of the total area.
