Abstract

This study aims to determine the species of ground cover plant as well as important value index, the level of species diversity and distribution pattern of ground cover in Nature Reserve and Nature Park of Telaga Warna. This research used the transect method and data collection were using field observation technique. The area of observation consists of three locations with different altitudes including 1400, 1500 and 1600 m asl. Each location is made of three transects that lengthwise the topography. Each transect consists of 10 sample plots measuring 1 x 1 meter with transects spaced 10 meters. Ground cover plant are found as many as 28 species consisting of 20 families. Based on the Important Value Index/INP, obtained the species that dominates at 1400 m asl is Impatiens chonoceras, while at 1500 and 1600 m asl is Scleria laevis. Based on the index of diversity was found that the level of diversity at each location is currently abundant. Based on the index of dispersion was found that the dispersion patterns of ground cover plant at each location is clumped.Keywords: ground cover plant, Nature Reserve and Nature Park of Telaga Warna

Abstract

Sungai Ciliwung sebagai salah satu perairan umum yang mengalir melewati berbagai daerah mulai dari wilayah yang belum terganggu sampai dengan wilayah kegiatan manusia. Penelitian tentang makrozoobentos masih sedikit oleh karena itu perlu dilakukan penelitian tentang makrozoobentos. Penelitian bertujuan untuk mengetahui keanekaragaman makrozoobentos di Sungai Ciliwung. Pengambilan sampel terbagi menjadi 3 titik. Stasiun I Puncak-Cisarua Kabupaten Bogor), Stasiun II di daerah bendungan Katulampa (Kota Bogor), dan Stasiun III di Kedung Halang (Kota Bogor). Pada setiap stasiun dilakukan pengulangan sebanyak tiga kali. Dari hasil penelitian diperoleh komposisi 7 spesies dari kelas Gastropoda yaitu Elimia sp, Pila sp, Floridobia sp, Tarebia sp, Ademietta sp, Pomacea canaliculata, dan Pleurocera sp. 1 spesies dari kelas Crustacea yaitu Scylla sp dan 1 spesies dari kelas Bivalvia yaitu Corbicula sp. Keaekaragaman tertinggi adalah pada stasiun I (Cisarua) dengan indeks keanekaragaman 0,544 dan keanekaragaman yang terendah terdapat pada stasiun III (Kedung Halang) tidak terdapat makrozoobentos. Kepadatan populasi yang didapat pada stasiun I (Cisarua) yang tertinggi jenis Tarebia sp dengan indeks kepadatan populasi 0,1188 dan terendah pada jenis Pila sp yaitu 0,006. Pada stasiun II (Katulampa) tertinggi jenis Elimia sp dengan indeks kepadatan populasi 0,1188 dan terendah pada jenis Tarebia sp dan Corbicula sp yaitu 0,006. Frekuensi kehadiran pada stasiun I (Cisarua) yang tertiggi pada jenis Elimia sp, Tarebia sp dan Ademietta sp dengan frekuensi kehadiran 100% dan yang terendah pada jenis Pila sp dan Parathelphusa sp dengan frekuensi kehadiran 33,3%. Pada stasiun II (Katulampa) yang tertinggi pada jenis Pomacea sp dan Elimia sp yaitu dengan frekuensi kehadiran 100% dan terendah pada jenis Tarebia sp dan Corbicula sp dengan frekuensi kehadiran 33,3%.Kata kunci: Makrozoobentos, Jaring Surber, Sungai Ciliwung

Abstract

Biopori is pore space or in the ground formed by living creatures, such as microorganisms of the soil and plant roots. The shape resembles biopori hole in the ground and forked branches and very effective to channel water and air into the soil. In order to make the hole biopori still function optimally it should be routine coupled with organic material, so in the hole biopori absorption will still take place in aerobic composting process by soil microorganisms.The addition of microbes in accelerating the process of degradation of the garbage that is by adding a inoculum composite comprising four microorganism Saccharomyces, Lactobacillus, Acetobacter sp., and Bacillus. The addition of the best treatment with the addition of inoculum and soil, have physical characteristics that resemble the physical characteristics of the soil.Key words: Biopori, organic waste, microbes

Abstract

The study was conducted at two locations, namely the headwaters and mid stream part Ciliwung. A teach location made six transects with 45m length of each transect. Each transect made 5 sample plots measuring 1x1m with the distance between sample plots is 10m. Then be identified, then calculated FR, KR, INP and Diversity Index Type. Based on the research results, There are 23 species of plants preventing erosion which is included in the 14 family. Ciliwung headwaters part there are 19 species of plants preventing erosion of the 12 family, with a percentage of 57,5% and the highest Importance Value Index was Panicum maximum of 41.83%. Ciliwung midstream part there are 15 species of plants preventing erosion of the 9 tribes, with a percentage 45,4% and the highest Importance Value Index was Pennisetum purpureum of 44.16%. Plant species diversity index prevention of erosion in watersheds (DAS) Ciliwung low with values ranging between 0,90-0,95.Key words: erosion control plants, watershed (DAS), Ciliwung

Abstract

The research Diversity and Potential paku (Pteridophyta) in The Taman Nasional Gede Pangrango Montain Cianjur have been done. Transek and plot sample method use in this research on three area of different altitude (1600, 1900, 2200 m above sea level). The result research show there were 56 species of ferns that include in 21 families. At an altitude of 1600 m above sea level diversity ferns include in the medium category with value 1,48, at an altitude of 1900 m above sea level diversity ferns include in the medium category with value 1,02, and altitude of 2200 m above sea level diversity ferns include in the low category with value 0,93. Ferns in the TNGGP have potensial for the surroundings communities Kebun Raya Cibodas.Key words : Ferns, diversity, Gede Pangrango Mountain.
