Butterflies are one type of insect found in the green open space of Pontianak City. Butterflies can be used as bioindicators of environmental changes because butterflies are very sensitive to biotic and abiotic factors (Rizal, 2007). This study aims to obtain data and analyze the diversity of butterfly species in the green open space of Pontianak City. The study used a field observation method with sweeping net techniques and explored areas in three habitats namely Sylva Untan Arboretum, Untan S1 Forestry Campus and West Kalimantan Governor's Hall Pavilion. The three green open spaces were chosen based on the density and diversity of the vegetation. The results of the study found 22 types of butterflies. The same six types are found in three different types of open green space, namely Leptosia nina, Agamemnon Graphium, Papilio polytes, Hipolimnas bolina, Eurema hecabe, and Appias lybithea. The species diversity index at the Arboretum has a value of 2.74, Campus S1 Forestry Untan with a value of 2.19 and Pendopo Park with a value of 2.02. This value indicates that species diversity in green open space is classified as medium.Keywords: butterfly diversity, green open space, bioindicator

The Pandanduri Dam has a function as a support for agricultural irrigation water and also supports community activities so that it will affect the quality of its waters. The quality of the water needs to be analyzed because it can affect the aquatic ecosystem. This study aims to determine the level of water pollution in the Pandanduri Dam based on the phytoplankton community from the Chlorophyta Division. This type of research is descriptive exploratory. Sampling was carried out at 5 stations that were haphazardly selected with ecological representativeness consideration. Phytoplankton data were analyzed using the abundance formula, Shannon-Wiener diversity index, PIELOU uniformity index, and Simpson dominance index. The phytoplankton from the Chlorophyta Division found in the Pandanduri Dam were 14 species that are Pediastrum duplex var. Gracillimum, Gonium sp. 1, Gonium sp. 2, Coelastrum reticulatum, Scenedesmus acuminatus, Cosmarium sp., Chlamydomonas nasuta, Chlamydomonas sp., Selenastrum capricornutum, Monoraphidium dybowskii, Monoraphidium contortum, Monoraphidium irregular, Westella botryoides, and Kirchneriella lunaris consisting of 4 orders (Sphaeropleales, Chlorococcales, Chlamydomonadales and Desmidiales) and 10 genera (Pediastrum, Coelastrum, Scenedesmus, Gonium, Cosmarium, Chlamydomonas, Selenastrum, Monoraphidium, Westella, and Kirchneriella). The species diversity index of 2.21 is classified as moderate diversity, the species uniformity index is 0.83 which indicates even species growth, and the species dominance index indicates that no species dominates with a value of 0.12. The level of water pollution in the Pandanduri Dam was found in the moderate pollution category (oligotrophic).

Phytoplankton is an organism that had an effect on life waters and can be used as the parameters in monitoring water quality. Distribution of phytoplankton in the waters can be for biomonitoring which can be used to make protection zone. This study will examine the distribution and composition of phytoplankton in The crab conservation area in Betahwalang Waters, Demak. This research divided into three stations in estuaries and the sea s. Each sampling was done once a month. Samples were taken using a plankton net. The results found three classes of phytoplankton, namely Bacillariophyceae class, Cyanophyceae class and Dinophyceae class. The number of genera found in the river area (37 genera), at the estuary station as much (38 genera) and the sea station as much (31 genera). Fluctuation in phytoplankton abundance at each station is quite varied. The abundance of phytoplankton in January was 1.030.400 cells/L, in February it was 936.800  cells/L, and in March it was 643.600 cells/L. The highest abundance occurs in the estuary area, then the river and the lowest in the sea. The value of species diversity index (H ') is in the range of 2.57-3.03. Uniformity index values range from 0.86 to 0.94. The dominance index from 0.06 to 0.14. Factors affecting the abundance and dominance of phytoplankton are water conditions and the rainy season. Fitoplankton merupakan organisme yang mempunyai pengaruh besar terhadap kehidupan di suatu perairan baik langsung maupun tidak langsung dan dijadikan sebagai salah satu parameter dalam pemantauan kualitas perairan.Fitoplankton di perairan dapat dijadikan suatu ukuran bahwa Kawasan tersebut dapat dijadikan sebagai zona perlindungan biota.Penelitian ini mengkaji fluktuasi fitolankton pada Kawasan konservasi rajungan di Perairan Betahwalang, Demak. Penelitian ini dilakukan pada 3 stasiun yang terletak disungai, muara sungai, dan laut. Pengambilan sampel dilakukan setiap bulan selama tiga bulan  menggunakan planktonnet. Hasil penelitian ditemukan 3 kelas yaitu kelas Bacillariophyceae, Cyanophyceae dan Dinophyceae.Jumlah genus yang ditemukan pada area sungai, muara sungai dan laut berturut-turut 37 genus, 38 genus dan 31 genus. Fluktuasi kelimpahan fitoplankton di setiap stasiun cukup bervariasi.Kelimpahan fitoplankton pada bulan Januari sebesar 1.030.400 sel/L, pada bulan Februari sebesar 936.800 sel/L, dan pada bulan Maret sebesar 643.600 sel/L. Kelimpahan tertinggi terjadi pada daerah muara, kemudian sungai dan terendah di laut. Sedangkan nilai indeks keanekaragaman jenis (H’) berada pada kisaran 2,57-3,03. Nilai indeks keseragaman berkisar 0,86-0,94. Sedangkan indeks dominasi berkisar 0,06-0,14. Faktor yang mempengaruhi kelimpahan dan dominasi fitoplankton adalah kondisi perairan dan musim hujan.

Diversity of butterfly species can develop well if in the habitat there are factors that support its population. Protected areas have a higher diversity of butterfly species than those land use conservation area. Beside taking forest product in term of wood or non woody materials, Forest Managemen Unit also provide environmental service such as Clean Water Shelter (PDAM) and Madi Dam. The location of the Madi Dam and Clean Water Shelter are the location that utilized by the communities, this area also have a high diversity of butterfly. The purpose of this study was to obtain data on the diversity of butterflies in the Forest Management Unit in the village of Tiga Berkat lumar sub-district Bengkayang regency. The method used in this research is the transect method. Direct sampling with insect nets is carried out on the transect line. The butterfly found were 28 species with 153 individuals from 4 families are Papilionidae (6 species), Nymphalidae (14 species), Pieridae (6 species) and Lycaenidae (2 species). Diversity index value is 2,98, abundance index value is 0,89, riches index value is 5,36, dominance index  value is 2,14, species similarity index value is 72,72 %.Keywords : Diversity, Butterfly, Forest Management Units
