Judul: Perencanaan ruang terbuka hijau di kawasan pembangkit listrik tenaga uap PT Krakatau Daya Listrik Cilegon Banten
Abstrak: Kota Cilegon, kota yang terletak di Provinsi Banten, dikenal sebagai kota industri, dan menjadi pusat industri di kawasan Banten bagian barat. Perkembangan industri di Cilegon dapat dilihat dari dibangunnya sebuah kawasan industri Krakatau Steel. Asupan listrik pada kawasan industri Krakatau Steel dikelola oleh Pembangkit Listrik Tenaga Uap PT Krakatau Daya Listrik (PT KDL). Saat ini, PT KDL menggunakan gas dan minyak residu sebagai bahan bakar pembangkit listrik. Penggunaan bahan bakar gas memang tidak merusak lingkungan karena bahan bakar gas tidak mengeluarkan polusi. Namun penggunaan minyak residu menghasilkan polusi, selain itu juga pengembangan kawasan di PT KDL akan menggunakan batubara sebagai bahan bakar dalam membangkitkan energi listrik. Masalah utama pembangkit listrik berbahan bakar batubara adalah pembangkitan listrik ini merupakan salah satu kontributor pencemaran gas CO2 yang terbesar. Selain itu, masalah lain yang dihasilkan adalah kebisingan dari kinerja mesin-mesin pembangkit listrik yang dapat mengganggu kenyamanan karyawan sehingga berdampak negatif bagi kinerja dan produktivitas karyawan. Oleh karena itu permasalahan ini perlu dikaji dan diselesaikan agar kondisi lingkungan tidak terdegradasi parah akibat pencemaran yang berasal dari kawasan industri. Salah satu upaya mengurangi masalah polusi udara dan kebisingan adalah dengan membuat ruang terbuka hijau di kawasan industri.

Judul: Penentuan Luasan Optimal Hutan Kota Berdasarkan Emisi Karbondioksida (CO2) di Kota Cilegon Provinsi Banten
Abstrak: Cilegon is one of the industrial cities that experience development are rapidly. Density of population activities such as transportation and industrial activity led to an increase in water and air pollution and temperature. This research was intented to know the optimal area of urban forest based on carbon dioxide emissions in the air that are generated by fuel oil, Liquid Petroleum Gas, coal, humans, cattle, and rice fields and also know the location of potentially managed as urban forest. methods of research conducted is the literature studies, interviews, preparation work, direct observation and ground check. Cilegon has eight locations of urban forest with a total area 26.11 ha. Carbon dioxide emissions are produced in Cilegon city amounted to 13240029 tons/year, necessitating the addition of city forest 227243.89 ha. The value of Carbon dioxide emissions in 2030 is 3924365870 ton, so land required is 67362298 ha. The potential for urban city is residential area, public cemetery, the beach, empty land industry with long term development plan, and road network.

Judul: Gambaran Leukosit Domba Ekor Tipis yang Diinfeksi Haemonchus contortus.
Abstrak: The aim of this study was to investigate the effect of Haemonchus contortus infection to white blood cell profile of Javanese thin tail sheep. Twenty males Javanese thin tailed sheep were divided into five groups, namely infected group of 500 L3, 1000 L3, 2000 L3, 4000 L3 and uninfective group as control. The blood and fecal samples were collected from rectum before and three weeks after infection. The blood samples were collected using venoject® from Jugular vein. The fecal samples were collected directly from rectum. The blood samples were examined to determine total of white blood cell (leukocytes) and white blood cell differential, whereas fecal samples to determine egg per gram. The result showed that Haemonchus contortus infections cause an increased total of leukocyte but were not significantly different among of level infection doses (P>0.05). Number of eosinophils were significantly different among uninfected group (P<0.05), but were not significantly different in number of lymphocyte, monocyte, and neutrophil (P>0.05). There where positively correlated significantly between the amount of egg per gram (EPG) and profile of eosinophil (P<0.05), however were negatively correlated significantly between the amount of egg per gram (EPG) and neutrophil’s profile (P<0.05). There where no correlation significantly between the amount of egg per gram (EPG) and profile of white blood cell, lymphocyte, and monocyte (P>0.05).
