Judul: Luasan Optimal Hutan Kota sebagai Penyerap CO2 dan Kesesuaiannya dengan Rencana Tata Ruang Wilayah di Kota Tangerang.
Abstrak: Tangerang City known as industrial area and residential area. The city has consumed a lot of energy, that lead to the increase of air pollution especially CO2 in atmosphere. One way to reduce level of air pollution is development of green open space, urban forest, and protected area within spatial planning of Tangerang City. The necessary of urban forest in the Tangerang City could be determined by CO2 absorption approach based on IPCC (Intergovermental Panel on Climate Change) method. The research aimed at estimating the optimal size of urban forest based on CO2 emission came from domestic, agriculture and industrial emission. Further, spatial suitability also were examined. Result showed that CO2 emissions amounted to 3188.9 Gg CO2/years in 2014. Meanwhile, the result of land cover classification revealed that the area of trees vegetation amounted to 1870.26 hectares and grass amounted to 1977.81 hectares. Both of trees vegetation and grass could only absorb 115.48 Gg CO2/years (3.62% of total emissions). The protected area established in land use plannning only 1421.06 Ha and therefore need a lot of additional urban forest, in fact there was no any urban forest established by the government.

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: Production Performance and Characteristics of Quail  Sperm (Coturnix-coturnix japonica) with Different concentrations of Yolk  Immunoglobulin
Abstrak: Puyuh diklasifikasikan menurut kekebalannya terhadap konsentrasi IgY yang berbeda, yang dapat memengaruhi produksi dan kinerja reproduksinya. Penelitian ini bertujuan untuk menganalisis konsentrasi IgY pada puyuh jantan dan membandingkan performa dan reproduksi pada konsentrasi IgY yang berbeda. Empat puluh dua puyuh jantan pada usia lima minggu digunakan dalam penelitian ini, 29 puyuh dengan konsentrasi IgY rendah dan 13 puyuh dengan konsentrasi IgY sedang. Performa produksi yang diamati adalah konsumsi pakan, bobot badan awal, bobot akhir, pertambahan bobot badan, konversi pakan, morbiditas, dan mortalitas. Penelitian ini juga mengamati bobot testis dan kualitas semen makroskopis dan mikroskopis untuk sifat-sifat reproduksi. Angka mortalitas dan morbiditas adalah variabel lain dalam penelitian ini juga diuji. Hasil penelitian menunjukkan bahwa puyuh jantan dengan konsentrasi IgY yang berbeda memiliki performa produksi yang sama (P>0,05). Berat testis, warna semen, dan pH semen tidak berbeda pada puyuh dengan konsentrasi IgY berbeda. Hasil penelitian menyimpulkan konsentrasi IgY pada puyuh jantan tidak memengaruhi performa produksi. Puyuh dengan konsentrasi IgY rendah memiliki konsistensi sperma yang lebih kental dan konsentrasi sperma yang lebih tinggi.
