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 sebagai Penyerap Karbondioksida di Kabupaten Tegal Jawa Tengah
Abstrak: Tegal Regency is a city that is experiencing rapid development. This development makes things such as people’s activities and transportation increases. It tends to ignore the presence of lands that have vegetation. It makes carbondioxide (CO2) gas emission from transportation and people increases. Urban forest concept is one of effective and efficient way to improve life quality in urban areas through its ability to absorb the CO2 from the air. This research was to explore optimal area of urban forest based on CO2 emissions that are generated by oil and gas fuel and humans. This research was done by field observation and literature studies. CO2 emissions in Tegal on 2011 amounted to 66 879 965.11 ton, so urban forest area that needed tends to 1 148 004.12 ha. Tegal Regency now have 1.03 ha of urban forest area, so it needs to be enhanced. CO2 emissions increases each year. It will reach to 80 427 512.27 ton on 2025, so it requires 1380549.70 ha of urban forest area on that year.

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.
