Judul: Pemetaan Kebisingan dan Penilaian Masyarakat Terhadap Kebisingan Banda r Udara (Studi Kasus Bandar Udara Sultan Syarif Kasim II Pekanbaru Riau)
Abstrak: Increasing in plane movement and expansion of area to hold bigger plane movement will cause problem to the environment, such as: increasing in noise emision (noises). The objective of this research were to mapping noise zone, analyze influence factor of society perception to noise, analyze influence factor of society willingness to stay or willingness to accept around Sultan Syarif Kasim II Airport Method used in this research were survey and noise measurement. The result of noisy area mapping to zone 1 was 16,251,665 m2, to zone 2 was 4,732,308 m2 and zone 3 was 2,434,037 m2. The factor that influencing society perception to noise were job, length of time , proverty rights, distance and noisy area. The factor influencing level of society willingness to stay arround Sultan Syarif Kasim II Airport were length of time, proverty values and proverty rights. Willingnes to accept society around Sultan Syarif Kasim II Airport were influeced by education, job, proverty rights, distance and noisy area.

Judul: Analisis pengaruh suhu udara terhadap intensitas kebisingan di bandar udara (studi kasus: bandar udara Ahmad Yani Semarang)
Abstrak: Bandar udara Ahmad Yani Semarang merupakan bandara yang sibuk karena hingga saat ini didarati pesawat terbang dengan jumlah rata-rata 33 unit per hari. Selain dampak positif sebagai pintu gerbang lalu lintas udara, keberadaan bandar udara juga memiliki dampak negatif yaitu kebisingan yang diterima masyarakat sekitar. Kondisi meteorologi seperti suhu udara mempengaruhi propagasi suara. Oleh karena itu, penelitian ini dilakukan untuk mengetahui intensitas kebisingan serta pengaruh suhu udara terhadap intensitas kebisingan yang terukur. Penelitian ini dilakukan pada empat titik yang mewakili prosedur pengukuran menurut ICAO (International Civil Aviation Organization) yaitu di apron, pelataran parkir terminal, perumahan Cakrawala, dan landasan pacu barat. Hasil rata-rata intensitas kebisingan yang terukur pada tanggal 19, 20, 21 dan 23 April 2012, diantara empat titik pengukuran, rata-rata intensitas kebisingan maksimum yang tercatat sebesar 80 dB(A) di apron dan rata-rata intensitas kebisingan minimum sebesar 53,5 dB(A) di perumahan Cakrawala. Pengaruh suhu udara terhadap intensitas kebisingan yang terukur pada penelitian ini tidak menunjukkan pengaruh yang jelas akibat sampel data tidak diukur pada suhu udara yang beragam. Pada lokasi apron dan perumahan Cakrawala menunjukkan terjadi penurunan intensitas kebisingan seiring dengan peningkatan suhu udara, sedangkan di lokasi pelataran parkir terminal dan landasan pacu barat menunjukkan terjadi peningkatan intensitas kebisingan yang terukur seiring dengan peningkatan suhu udara….

Judul: Biology Of Columbia Lance Nematode (Hoplolaimus Columbus Sher) On Soybean Excised Root Culture
Abstrak: S. Supramana, S. A. Lewis,.J. D. Mueller, B. A. Fortnum, and R. E. Ballard. 2001. Biology of Columbia lance nematod. ~ (Hoplolaimus columbus Sher) on soybean excised root culture. Nematropica 31 :283-2~)O. Feeding, egg development and oviposition, embryology, and postembtyonic development or Hoplolaimus col'lmbuswere observed on soybean (cultivar Hutcheson) excised root culture in Gam borg's B5 medium (pH 5.7,1.3% agar). Petri plate sterile cultures were placed inverted on a heated microscope stage (30°C) and observations were conducted using a color video camera and a time lapse digital videoca:;sette recorder. Oocytes were obsetved in each gonad 38 hours after feeding commenced and all egg possessing a terminal stalk was laid 96 hours later. Eggs were deposited it, the one-celled stag~ and a total of 217 hours (9 days) was required for a"newly laid egg to develop into a hatching second-stage juvenile at 30°C. Postembryonic development consisted of threejuvenile stages and an adult female with prior feeding occurring before molts and oviposition. The nematode fed ectoparasiticallyon the subepidermal cells and endoparasitically in the cortex and outer vascular tissue and remained at the infection site for 2·9 days. Key words: Columbia lance nematode, embryology, excised root culture, feeding behavior, HOfilo{aimus columbus, life cycle, oviposition, postembryonic development, soybean.
