Judul: Effect of vegetation and ambient temperature to absorbtion of NO2 gas pollutant
Abstrak: Street side green belt giving an esthetics value and increasing environmental quality. However existence of street side green belt in Indonesia, especially in urban area shows toward degradation of their quality. This thing caused by increasing of construction in urban, such as; infrastructure, settlement, commerce and industrial activity and transportation. Negative impact of construction in urban area is lowering of the environmental quality. The real form of degradation environmental quality is incidence of environmental contamination problem like ; water, soil and air pollution. Pollution problem can be reduced through by revegetation of town or urban forest. Plant can lessen pollution problem around the street through absorbtion of gas pollutant and adsorption of particle at leaf surface. To measure absorption of NO2 gas pollutant by plant of leguminoseae/fabaceae exposure to gas 15NO2 in gas chamber. Plant is exposured by gas during 60 minutes at concentration of 3 ppm ( v/v). Exposure treatment conducted at condition of temperature 30°C and 20°C, light intensity 1000 luxes and relative humidity of 60% twice replication. Plant species were exposured consisted of : flamboyan, asam jawa, petai, lamtoro, sengon, saga pohon, kaliandra and gamal. After plant were treated with gas 15NO2 , parts of plant cut and disjointed between roots, bar and leaf. After dried at temperature 80°C during 48 hours, every part of the plant were milled to be smooth. Total nitrogen content is analysed with kjeldahl method. After sample is prepared in the form of liquid, abundance 15N is analysed with spectrometer emission (NOI-6PC Analyzer). Result of research shows level of 15N absorption varied. Among 8 plant absorption ranged from 18,96 μg/g - 44,98 μg/g at temperature 30°C and from 13,90 μg/g - 26,99 μg/g at temperature 20°C. Plants which have the highest absorption is petai ( 44,98 μ g/g) and the lowest is flamboyan ( 13,90 μ g/g). Species that having highest level absorption suggested to be utilized in street side landscape plants functioned to lessen air pollution, especially gas NO2. stomata size has a positive correlation to absorption of gas 15N at both temperature, while respiration rate has a positive correlation to absorption rate on temperature of 30ºC and doesn't has an effect at temperature 20ºC. Absorption of NO2 is higher on 30ºC, than on 20ºC.

Judul: Efektivitas Jalur Hijau Jalan Dalam Mengurangi Polutan Gas No2 Di Jalan Tol Jagorawi
Abstrak: Commonly, every big cities has a lot of factories and a high amount of vehicles that contribute to the air pollution which can lead to the decreasing of urban landscape quality. NO2 pollutant which is emitted by vehicles on the road can be reduced by modifying a landscape such as utilization of roadside vegetation. The aim of the research was to analyze the NO2 concentration distribution and also to analyze the effectiveness of Mahoni (Swietenia macrophylla) and Glodogan Bulat (Polyalthia fragrans) in reducing NO2 pollutant concentration in the air. This research was conducted in three different parts of the roadside vegetation of Jagorawi highway, there were plot I which vegetation was Mahoni (Swietenia macrophylla), Plot II which vegetation was Glodogan Bulat (Polyalthia fragrans), and Plot III which did not has trees (control). The canopy density of Mahoni vegetation (Plot I) and Glodogan Bulat vegetation (Plot II) were analyzed by Leaf Area Index (LAI) Method using Hemisphericalview Canopy Analyzer and measured by HemiView2.1 Canopy Analyzer software. NO2 concentrations were analyzed by Griess-Saltzman method performed by Inviromental research center, Bogor Agricultural University. The purpose of leaves sampling of Mahoni and Glodogan Bulat vegetations at the highway and BUPERTA (as a control) conducted on August 27th and September 27th in 2015 was to analyzed total N content on leaves as an indicator of NO2 absorption in the air. Total N content on leaves were analyzed by Kjendhal Method at Agronomy and Horticulture (AGH) Laboratory. The results of the analysis showed the distribution of NO2 concentration at Plot I (Mahoni) declined 52.1% and 84.8% in distance of 10 and 30 m respectivety. Meanwhile, the NO2 concentrations at Plot II (Glodogan Bulat) rise at 10 m distance on the percentage of 21.1% and declined at 30 m distance on the percentage of 18.1%. Plot III declining of NO2 concentrations tend to be consistent at a distance of 10 m at 49.4% and 30 m at 43.3% from the pollutant source. The absorption effectivity of NO2 by Mahoni was greater than control in the amount of 41.4% and also was greater than Glodogan Bulat in the amount of 66.7%. The results of Leaf Area Index (LAI) measurement showed that Glodogan Bulat has a higher canopy surface than Mahoni. However, Mahoni effectiveness of NO2 absorption was better than Glodogan Bulat. This was reinforced by the increasing of difference in the percentage of total N of Mahoni leaves which were higher than Glodogan Bulat leaves.

Judul: Hydatidosis Pada Anjing
Abstrak: Hydatidosis disebut juga echinococcosis merupakan penyakit parasiter yang menyerang hewan, disebabkan oleh genus Echinococcus dan salah satu spesies pada anjing yang bersifat kosmopolitan serta pernah timbul di Indonesia adalah Echinococcus granulosus. Echinococcus granulosus merupakan cacing pita yang sangat kecil panjangnya hanya 2-5 mm, terdiri dari scolex, neck, dan 3-4 proglottid. Scolex mempunyai 4 sucker dan sebuah rostellum yang dilengkapi dengan 2 baris kait yang masing-masing terdiri dari 30 buah. Kait yang besar panjangnya 33.2-39.8 u sedangkan yang kecil 22.1-34 u. Proglottid yang pertama immature, yang kedua mature, dan yang ketiga proglottid gravid. Lubang kelamin terletak disebelah lateral berselang-seling tidak beraturan, testes berjumlah 38-52 buah. Ovariumnya berbentuk seperti ginjal dan uterusnya mempunyai diverticulum lateral. Jenis cacing ini yang ditemukan di Indonesia tidak mempunyai neck. Siklus hidup E. granulosus memerlukan induk semang intermediate untuk perkembangan telur menjadi kista dan induk semang defenitif untuk perkembangan kista menjadi cacing dewasa. Domba merupakan hewan yang paling subur untuk perkembangan stadium kistanya dan bersama anjing kedua hewan ini memegang peranan penting dalam penyebaran penyakit ini. Domba biasanya terinfeksi melalui makanan atau minuman yang terkontaminasi telur cacing. Telur-telur yang tertelan ini akan menetas menjadi oncosphere, lalu menembus dinding usus masuk ke saluran limfe atau vena kecil di mesenterium yang kemudian dengan aliran darah terbawa ke seluruh tubuh. Oncosphere ini biasanya menetap di hati dan paru-paru. Bila oncosphere telah berubah menjadi kista dan termakan oleh anjing maka infeksi dapat berlangsung pada anjing hingga mencapai bentuk cacing dewasa. Penyakit ini telah tersebar di seluruh dunia, mencakup banyak hewan tanpa membedakan umur dan jenis kelamin. Menyebabkan kerugian ekonomi yang besar terhadap ternak bahkan dapat menyerang manusia. Akibat adanya kista adalah timbulnya kelemahan, anorexia, dyspnoe, kurus, dan akhirnya kematian dari induk semang. Kebersihan lingkungan terutama yang berkaitan dengan anjing adalah tindakan pencegahan yang utama sedangkan tindakan pembedahan merupakan salah satu usaha yang agak memuaskan dalam penanganan penyakit ini.
