Judul: Formulation of Indoor Air Comfort Index for Worship Buildings
Abstrak: Dua fungsi utama dari fasilitas umum adalah memberikan pelayanan kepada penduduk dan menjaga kualitas lingkungan. Belum ditemukan indeks yang menyatakan parameter kenyamanan udara dalam ruang secara kuantitatif di tempat ibadah. Penelitian dilakukan untuk mengidentifikasi dan memformulasikan indeks kenyamanan udara dalam ruang pada tempat ibadah berdasarkan kondisi temperatur, kebisingan, kebauan, kelembaban relatif, dan intensitas cahaya yang dapat menjadi rekomendasi terbaik bagi pemerintah kabupaten/kota. Penelitian dilakukan berdasarkan metode kualitatif dan kuantitatif. Metode kualitatif berdasarkan pengisian kuesioner oleh responden dan metode kuantitatif berdasarkan pengukuran lima parameter di lokasi penelitian. Formula didapatkan dari hasil pembobotan berdasarkan kuesioner dan nilai indeks untuk setiap parameter. Indeks kenyamanan udara dalam ruang diperoleh berdasarkan lima tingkatan yaitu tidak nyaman, kurang nyaman, nyaman, cukup nyaman, dan sangat nyaman. Hasil penelitian memiliki nilai indeks tempat ibadah 4.0 pada Vihara Tridharma yang dinyatakan nyaman, nilai indeks 2.9 pada Gereja Immanuel yang dinyatakan cukup nyaman, dan kisaran nilai indeks 3.1-3.8 pada tujuh lokasi lainnya yang dinyatakan nyaman., Two main functions of public facilities are providing services to residents and maintaining environmental quality. There is currently no index that states the parameters of indoor air comfort quantitatively for worship buildings. The research has identified and formulated an indoor air comfort index for worship buildings based on temperature, noise, odour, relative humidity, and light intensity that can be the best recommendations for district/city governments. The research has conducted using qualitative and quantitative methods. The qualitative method is based on filling the questionnaires by respondents and the quantitative method is based on the measurement of five parameters at the research site. The formulation obtained from the results of the weighting of the questionnaire and the index for each parameter. The indoor air comfort index is obtained based on five levels: uncomfortable, less comfortable, quite comfortable, comfortable, and extremely comfortable. The results of the research place of worship gave an index value of 4.0 at Tridharma temple that has declared comfortable, an index value of 2.9 at Church of Immanuel that have declared quite comfortable, and a range of index values of 3.1-3.8 at seven other sites that has declared comfortable.

Judul: Formulation of Indoor Air Comfort Index for Sukaraja Sub-district Office, Bogor Regency
Abstrak: Faktor yang perlu diperhatikan dalam perancangan dan pembangunan gedung kantor adalah kenyamanan pekerja terhadap gedung tersebut. Penelitian ini dilakukan untuk memformulasikan suatu indeks kenyamanan udara dalam ruang (KUR) dengan mempertimbangkan parameter temperatur, kelembaban relatif, kebisingan, intensitas cahaya, dan kebauan. Pengukuran yang dilakukan yaitu temperatur, tingkat kebisingan dan intensitas cahaya, sedangkan untuk mengukur kesan bau digunakan skala hedonisme kebauan. Pembobotan dilakukan untuk mengetahui tingkat pengaruh dari masing-masing parameter berdasarkan 58 responden. Diperoleh faktor pembobot untuk temperatur 0.28, kelembaban relatif 0.16, kebisingan 0.19, intensitas cahaya 0.22, dan kebauan 0.15. Formula indeks KUR merupakan total perkalian antara indeks masing-masing parameter dan nilai faktor pembobotnya. Indeks KUR ditetapkan lima tingkatan, dari sangat nyaman hingga tidak nyaman. Berdasarkan hasil perhitungan, Ruang Camat dan Ruang Sekretaris Camat mendapatkan indeks KUR 4.1 (sangat nyaman), Ruang Pemerintahan dan Ruang Ekonomi Pembangunan mendapatkan indeks KUR sebesar 3.0 dan Ruang PKK mendapatkan indeks KUR 2.6 (cukup nyaman), serta delapan ruangan lainnya mendapatkan indeks KUR berkisar 3.1-3.8 (nyaman)., The factor that needs to be considered in the design and construction of an office building is worker comfort. This research was conducted to formulate the indoor air comfort index (IAC) by considering the parameters of temperature, relative humidity, noise, light intensity, and odour. Measurements taken are temperature, noise level and light intensity, while to measure odour impression, odour hedonism scale is used. Weighting is carried out to determine the level of influence of each parameter based on 58 respondents. The weighting factors were obtained for temperature 0.28, relative humidity 0.16, noise 0.19, light intensity 0.22, and odour 0.15. The IAC index formula is the total multiplication between the index of each parameter and the weighting factor value. The IAC index is set at five levels, from very comfortable to uncomfortable. Based on the results of the calculation, Sub-district head’s room and Secretary’s room obtained an IAC index of 4.1 (very comfortable), Government’s room and Economic Development’s room obtained an IAC index of 3.0 and PKK room got an IAC index of 2.6 (quite comfortable), and ten other rooms got an IAC index ranging from 3.1-3.8 (comfortable).

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.
