Identity development is done in Excel Nusantara University Experimental Station and Nation village in monoculture planting Cogrek with a wide scale, but often face exploitation teak plantations by the pest problem which is one of the impact of the production quality. Therefore this research needs to be done by identifying pests in the village JUN cogrek.This study aims to determine the types of pests or signs of gelaja attacks, the number of trees affected and the intensity of the damage was found in teak (Tectona grandis Lf) plantations in the village in Cogrek. The sampling done by making extensive plot with size 0.1 ha (20 mx 50 m) with a sampling intensity of 10% of the crop stand and trubusan Teak (Tectona grandis Lf) by means of systematic random sampling. Measured parameter type and pests that attack stands trubusan Teak, intensity of damage by pests and the number of trees attacked.The results showed that the types of pests that are found in plant stands about 7 species, whereas in plants trubusan about 8 types of pests are found. For the number of trees attacked by as many as 101 trees on the plant stand while the number of trees that were attacked on 88 trubusan plant trees and intensity of pest damage on trubusan averaged amounted to 11.8% leaves and stems are attacked 0.7%. All the results of the intensity calculations pest damage can be categorized mild attack.

Konyal (Passiflora suberosa L) is one of the IAS species and it’s are very big influence on the growth of endemic species in RPTN Mandalawangi. Konyal spread very quickly and can kill their host trees pose a major threat to endemic plant species. In connection with the distribution konyal, it is necessary the existence of a preventive step to support konyal control is to map the distribution of konyal in RPTN Mandalawangi to determine priority areas that must be controlled immediately.Mapping the distribution of IAS konyal (Passiflora suberosa L) was conducted to determine and identify konyal (Passiflora suberosa L) and its distribution. Later this study is expected to be a reference for management to control the distribution of konyal (Passiflora suberosa L)

People's lives around the Nature Reserve (CA) has a very close interaction with the natural resources around them. One of them is the interaction associated with the use of plants (ethnobotany). Documenting knowledge society CA Dungus Iwul ethnobotany essential to keep the knowledge society CA Dungus Iwul in the utilization of the plant is not lost. This study aims to determine the potential of useful plants in the region CA Dungus Iwul and examine the use of plants by people around CA Dungus Iwul (ethnobotany). Ethnobotany study conducted by interview and to determine the potential of plants useful in the CA Dungus Iwul done with vegetation analysis. The number of plant species that are found from the analysis of the vegetation in the area Dungus Iwul CA acquired as many as 43 species of 25famili. Most useful plant species are as many as 21 species of medicinal plants. While the study of ethnobotany identified as many as 30 species of 21 families and each has been grouped into 11 groups of usefulness, where the species is found mostly serves as a group of as many as 25 species of medicinal plants. Habitus most dominating of the results of the analysis of seedling and plant vegetation is under the most dominating family is Arecaceae, while on the study of ethnobotany is habitus of shrubs with family Zingiberaceae. Based on the percentage of habitat types, the plant most widely used by the public is a plant cultivated 20 species (67%) and 10 species (33%) is a wild plant, which used only a small portion of the area CA Dungus Iwul about 7 species. Their use of plants that originate from within the CA Dungus Iwul indicate that there has been interaction, ie interaction in the form of plant utilization. However, the interaction is still relatively low so that the possibility of damage to a small area.

Observation on the Water Quality of Cisadane River in the Upstream Part Using Macroinvertebrates as The IndikatorÂ Â Â Â Â Â Â Â Â Water is an important thing for either human life or other creatures on the earth.Â Water posses a lot of necesities, among of them is to fullfill domestics, industries, and agriculture. For this purposes people often take from rivers.Â River Cisedane is one of rivers that available in Bogor City, having water catchment area of 1100 km2 and is one of main rivers in West Java and Banten Province. One procedure for testing water quality of rivers is to see the invertebrate animals available in the river, because some species are very sensitive for pollution. There were three points in the reserch area that were in upperpart area was Rancamaya, middle area was Pasir Jaya, and the lower area was Situ Gede.Â Water quality value index in Rancamaya (Upper part) was 5.42, included middle level of water pollution. In Pasir Jaya (middle point) was 4.75, included polluted water level, and in SituÂ Gede (lower prt) was 4.28 included more pollutud water level. Overall of observed research area were the lower part of river the worse pollution available. The pollution available in the research area was caused by domestics waste from inhabitant and other chemical waste from agriculture.Keyword :Â Mikroinvertebrata, Cisadane, water quality, upper river partÂ ABSTRAKÂ Â Â Â Â Â Â Â Â Air merupakan salah satu unsur yang sangat penting bagi kelangsungan hidup manusia maupun mahkluk hidup lainnya yang ada di muka bumi. Air memiliki banyak manfaat, diantaranya untuk memenuhi kebutuhan rumah tangga, industri dan pertanian. Untuk memanfaatkan air tersebut biasanya masyarakat mengambil air dari satu sungai pada suatu Daerah Aliran Sungai (DAS). Salah satu DAS yang terdapat di Kota Bogor yaitu DAS Cisadane dengan daerah tangkapan air seluas 1.100 km2, selain itu DAS Cisadane Â merupakan aliran sungai utama di Propinsi Banten dan Jawa Barat. Salah satu cara untuk menilai kualitas air sungai adalah dengan melihat keberadaan makroinvertebrata yang hidup di sungai tersebut. Makroinvertebrata dapat memberikan petunjuk adanya pencemar, karena jenis-jenis tertentu sangat peka terhadap pencemaran. Maka berdasarkan hal tersebut penelitian ini akan mengidentifikasi adanya makro-invertebrata di sungai yang merupakan bioindikator kualitas airnya. Tiga titik pengambilan sampel makro-invertebrata di hulu sungai Cisedane yaitu di bagian atas peneltian (Daerah Rancamaya), di bagian tengah penelitian Â (Pasir Jaya) dan di bagian bawah penelitian (Situ Gede). Nilai indeks kualitas air di bagian atas penelitian, yaitu di daerah Desa Rancamaya adalah 5,42. Itu menunjukan bahwa kualitas air di daerah tersebut masuk air berpolusi sedang. Pada lokasi penelitian di bagian tengah, yaitu Daerah Desa Pasir Jaya indeks kualitas air nya adalah 4,75. Itu menunjukan bahwa kualitas air di sana masuk air kotor. Sedangkan di bagian bawah penelitian, yaitu daerah Desa Situ Gede indeks kualitas air nya adalah 4,28. Itu menunjukan bahwa kualitas air di sana masuk air kotor. Dari Nilai Indeks Kualitas air di seluruh lokasi hulu sungai penelitian menunjukan bahwa semakin ke bawah kualitas air sungai semakin kotor. Kualitas air di sana diduga diakibatkan oleh sampah atau limbah organik yang berasal dari rumah tangga. Selain itu, kualitas air di sana diduga disebabkan oleh bahan â€“bahan kimia berbahaya yang berasal dari penggunaan pupuk, pestisida di areal pertanian.Â Kata kunci : Mikroinvertebrata, Cisadane, kualitas air, hulu.
