Judul: Perencanaan Jalur Hijau untuk Mengurangi Polusi Partikel Akibat Aktivitas Transportasi pada Simpang Susun Cawang, Jakarta Timur
Abstrak: Transportation activities on the street is on the increase and causing negative impact namely pollution. To overcome this under ideal condition, an approach that can be used as one of the solutions is green spaces such as greenery. Greenery of streetside can decrease pollution on its surrounding areas. The location of this research was Cawang interchange, East Jakarta. There were two objectives which were provided by the research: 1) to measure dust that was adsorbed by the greenery of Cawang interchange and 2) to arrange a planting plan of Cawang interchange greenery. The process of this research consist of several phases e.g. commission, research, analysis, and synthesis. Otherwise, gravimetry method was used to found the full measure of greenery capacity in adsorbing particles (dust). This research showed that Ficus benjamina was the species which has the highest capacity in adsorbing dust beside other three sample species (Mimusoph elengi, Cerbera manghas, and Polyalthia fragrans). Therefore, it was important to consider sort of species, number, and location pattern of the greenery in arranging the planting plan to reduce particles. The output of this research was planting plan of Cawang interchange greenery.

Judul: Perencanaan Tata Hijau Simpang Susun Dawuan Jalan Tol Cikampek
Abstrak: Traffic jam have been the most pressing issues in big city. These problems were caused by human population growth, economic growth, and transportation. Vehicle activities increase air pollution on high level. To overcome this problem, green open space in the site is needed as a solution. This research is located in Dawuan interchange at Cikampek toll road. The purpose of this research are to measure total of particle limited by traffic and tree population needed, and to arrange planting plan in Dawuan interchange. The process of this research consists of several phases e.g. commission, research, analysis, and synthesis.The result of the research is arrangement of vegetation by the functions as buffer, direction, conservation, identitiy, and aesthetic. Total emission of particle produced by vehicle approximately is 233.723 g/day, and to adsorb the particle emission 8.958 trees are needed. In case, the site only can be planted by 5.229 trees, so that 3.729 trees still needed to adsorb those emission of dust. Recommended vegetation are Samanea saman, Acassia auriculiformis, and Melaleuca leucadendra.

Judul: Pengujian Virus Newcastle Disease Gen VII Isolat Lapang Sebagai Virus Standar Pada Uji Tantang Vaksin
Abstrak: This study was conducted to determine the standard of Newcastle disease virus Gene VII field isolate as a virus challenge to vaccine test. A virus suspension that has previously been tested by HA test then titrated with EID50 using 30 Specific Pathogen Free (SPF) of 10 day old chicken embryonated eggs. In addition, chicken lethal dose50 (CLD50) test were used to determine the virus titer that could cause 50% death of the chicken population. The CLD50 test was used 25 day-old-chickens (DOC) divided into 5 groups. The virus was diluted from 10-1 to 10-8. The 104 to 10-8 dilution of NDV was infected to every group of chicken via eyedrop and intranasal with 0.1 ml/chicken dosage. Haemagglutination test showed that the allantoic fluid were contain high titers of NDV is 512 HAU. The infective NDV that had been titrated by EID50 test showed the virus titers is 109 EID50/0.1 ml or 1010 EID50/ml and the virus titers of CLD50 test e.i 106.48 CLD50/0.1 ml or 107.48 CLD50/ml. These results can be concluded that the NDV Gene VII field isolates were most appropriate to be used as a standard virus to vaccine test
