KEANEKARAGAMAN JENIS PAKU-PAKUAN (Pteridophyta) TERESTRIAL DI LINGKUNGAN ARBORETUM SYLVA UNIVERSITAS TANJUNGPURA PONTIANAK
Get PDFThis study aims to determine the diversity of terrestrial pteridophyta species (pteridophyta) at the University Arboretum Sylva Tanjungpura Pontianak. The objek of the study was to observe the types of terrestrial fern plants found in research plots based on where they grew. This research use survey method with double plot area is 10 x 5 meters, taken ± 10 % of the area of the Arboretum Sylva environment ( 32 observation plots). The result showed that the number of fern plants obtained from the observation plots of 1 to 32 plot were 8 species of terrestrial nails belonging to 5 families with 1138 individuals, the type of nail found was Asplenium longissimum, Asplenium belangeri Bori, Lygodium circinatum SW, Angiospteris avecta Hoffm, Nephrolepis hirsutula Forst, Nephrolepis bisserata SW, Stenochleana palustris Burm, and Lygodium scandes L. The value of dominance Index (C) in the study site is low because the index value of dominance of all plots does not exceed the value of 1. This shows that the community does not find one or two dominant plant species that dominate in that location.Keywords: diversity, fern nail plant, terrestrial

Get PDFMangrove Forest in Sungai Bakau Kecil Village is located in Mempawah Timur District, Mempawah Regency. Mangrove ecosystem which has high economic and ecological value. Various species of mangroves, fish, shrimp, crabs and birds can be found in this area. The purpose of this study is to describe the influence of texture, water content and soil salinity to abundance of shellfish in mangrove forest Sungai Bakau Kecil Village Mempawah District. This research was conducted by using survey method, soil sampling technique and mangrove clam done purposively (purposive sampling). Soil samples were tested in the laboratory to see some observed parameters such as soil texture, soil water content, and salinity. Data analysis using descriptive. The texture of soil in mangrove forest of Sungai Bakau Kecil Village is a dusty clay loam soil classes. Soil texture does not determine the presence of shellfish in the mangrove forest of Sungai Bakau Kecil Village because the habitat of the shell is in the muddy or sandy ground. Shellfish can also live on the ground with dusty clay loam soil classes. Salinity suitable for shellfish with salinity value is 4.18 ppt, 4.27 pptdan 4.22 ppt with abundance of 3 / m². The soil water content that determines the abundance of shellfish in the mangrove forest of Sungai Bakau Kecil Village with a range of values that is 36.57%, 41.33% and 50.61% with abundance 3 / m² Other factors that influence the presence of shellfish is human activity which takes the shellfish in the forest and the seasonal factor also determines the amount of shellfish in the forest.Keywords: Abundance, Inland Water Content, Mangrove forest, Salinity, Texture

Get PDFIndonesia is one of the countries that has 20% of the world's primate species, one of the primate species is an orangutan. This study aims to determine the behavior of Kalimantan orangutan (Pongo pygmaeus). The research was conducted in Conservation Forest Area, PT. Kayung Agro Lestari (KAL), Ketapang District. This observation was conducted by using focal animal sampling method on three individual orangutan found in conservation forest area with different age and sex. The three individual orangutan were observed in the morning after the orangutan got up and out of their nest until the orangutan made their nests late in the evening. The data of orangutan behavior is recorded with a duration of time every two minutes.Adult orangutan observed in conservation forest areas spend more time resting, followed by moving and eating activities, this behavior is different from younger orangutan who engage in more eating, moving and resting activities.. The observed orangutan do a lot of activities in the morning and afternoon, while in the daytime activities are mostly done is a rest activity.Keywords: Behavior Of Orangutan, Concervation Forest, Pongo pygmaeus.Indonesia is one of the countries that has 20% of the world's primate species, one of the primate species is an orangutan.

Get PDFDragonfly is an indicator to environment and ecosystem in a particular area. It is also known as a balancing predator to another insects’ population. Various types of dragonfly are affected by some factors such as habitat conditions and the foods. Various types of dragonfly can be found in swamland, rice fields, flooded area, and also some locations around Universitas Tanjungpura. This research aims to convey information about various types of dragonfly in the area of universitas tanjungpura and also to define the index of variety of dragonfly types (H), equalization index (e), domination index (D), and species similarity (IS). This research took two weeks of fieldwork by applying purposive sampling, which was started from 5th – 15 th April, 2018. Where the researcher is free to down each location seen from the large number of dragonflies are found. Then each location specified each plot with a distance of 15 meters each point of view of forming a circle pattern diameter 30 meters. The researcher found that 16 type of dragonfly consist of 13 type categorized as Subordo Anisptera and 3 type categorized as Subordo Zygoptera. The 13 Subordo Anisoptera consist of 12 types in libellulidae family and 1 type in Gomphidae family. The other 3 Subordo Zygoptera are in the the categoryof Coenagrionidae. This research shows that the role of dragonfly as a bioindicator and the predator of particular environment.

Get PDFRecent forest and land fire issues attract more national and international attention as environmental and economic issues. The Government through its authority has issued several regulations in order to achieve the success of forest and land fire prevention. One of the regulations is Law no. 32 of 2009 Concerning Environmental Protection and Management Article 69 (1) letter h "everyone is prohibited from clearing the land by burning". Penjawaan Village is a village where most of the people are livelihood in agriculture and plantation sector. The farmers in the village are known to still use shifting cultivation farming system by burning technique.

Therefore, this study aims to describe the attitude of the community of Penjawaan Village and explain the factors that influence the attitude of the community towards the implementation of the ban on opening the land by burning. The research used survey method with interview and sampling of respondents was done by purposive random sampling technique. The analysis used is descriptive analysis and inferential analysis of Kendall Tau correlation. The results showed that the attitude of the community of Penjawaan Village against the implementation of the prohibition of opening the land by burning tends to be neutral, this is because the community just know about the regulation. In addition, the lack of modern agricultural technological tools and community knowledge of how to use them for the processing of land into a permanent agricultural pattern in the village is still minimal. Significantly related to the attitude of the community of Penjawaan Village is the perception and dependence on the forest. This happens because people realize that clearing the land by burning will threaten the existence of the forest. In addition, the community still utilizes the surrounding forest products for daily needs.Keywords: Community Attitudes, How to Burn, Land, Regulations

However, information about potential stands in the Tembawang forest has not yet been known. Therefore, this research aimed to find out how was the potential forest in the Tembawang. This research used the Sistematic Strip Sampling method by away of cruissing 100 % and analyzed using the formula of the volume unit. The results showed that the total volume of the stands in this forest was 319,98 m³, it consisted of: 86,112 m³ for Dipterocarpaceae; 217,687 m³ for Non Dipterocarpaceae; 16,181 m³ for species protected (Eusideroxylon zwageri). The average of total volume per hectare was 54,791 m³/ha. Tree spesies which had the highest potential of stands total volume was Tengkawang (Shorea sp.) with volume 69,925 m³. Based on the growth level, there ware 53 tree/ha, 55 poles/ha, 85 sapling/ha and 75 seedling/ha. The sufficiency number potential of stems based on the standards of the Departemant Kehutanan in 1989 at the level of the tree was quite, while at the level of seedling, sapling and pole was still less.Keywords: Potential stands, Tembawang
