Judul: Periode Kenyamanan Manusia dalam Mushola Surau Gadang, Sumatera Barat
Abstrak: This study conducted in Mosque Surau Gadang, Koto Baru, West Sumatera for 25 days. Mosque of Surau Gadang was approximately 80% made of wood. The study was porposed to measure the daily cycle of climate and weather element limited to sunlinght intensity in outside Mosque of Surau Gadang, temperature and RH inside Mosque of Surau Gadang measured using tool Environment meter Krisbow KW06-291. Four models (linear sine, exponentialsine, power-sine and logarithmic –sine) were conducted to fit the sunlight intensity. Linear sine curve was the best among others. The sunlight intensity was dominated by uncomfort zone at 07:53-17:39 GMT+7, the rest is 06:23-07:53 GMT+7 and 17:39-18:27 GMT+7 sunlight intensity in comfort zone. Temperature inside Mosque of Surau Gadang are in a comfort zone all day either during the day or night, because Mosque of Surau Gadang located in the hills. Humidity (RH) is in two zones: comfort enough (at 10:00-18:30 GMT+7) and uncomfort (at 18:30-10:00 GMT+7). The combination of temperature and RH is a good indicator to measure the level of human comfort. Temperature and RH used to measure discomfort index Thom and heat index US NOAA. Base on Thom’s classification, the level of human comfort inside Surau Gadang’s Mosque located in two zones B and C. Zone B showing few people feel uncomfort at 20:00-09:15 GMT+7, zone C showing a half people feel uncomfort at 09:15-20:00 GMT+7, while, according to the classification of the US NOAA, comfort zone can be felt at 00:00-07:00 GMT+7, caution zone at 07:00-12:30 GMT+7 and 17:50-00:00 GMT+7, extreme caution at 12:30-17:50 GMT+7.

Judul: Determination of Indoor Comfort Level at The Mosque in The Bogor Area
Abstrak: Masjid sebagai fasilitas umum untuk memenuhi kebutuhan peribadatan harus memberikan ketenangan dan ketentraman pada pengunjung dan lingkungannya. Penelitian ini dilakukan untuk mengetahui tingkat kenyamanan dalam ruang pada masjid berdasarkan kenyamanan termal, kenyamanan visual, dan kenyamanan audial. Penelitian dilakukan dengan metode kualitatif pada pengisian kuesioner oleh responden dan metode kuantitatif didasarkan pada pengukuran tiga parameter di lokasi penelitian. Penelitian pada keenam masjid di Kawasan Bogor memberikan nilai rata-rata temperatur udara sebesar 26,2°C; kelembaban relatif udara sebesar 82,6%; intensitas pencahayaan sebesar 228 lux; dan tingkat kebisingan sebesar 47 dB(A). Temperatur udara yang memenuhi standar baku mutu terdapat pada Masjid Besar An-Nuur dan Masjid Al Hurriyyah. Kelembaban relatif udara pada keenam masjid tidak memenuhi baku mutu. Intensitas pencahayaan pada enam masjid yang diukur belum memenuhi standar baku mutu. Tiga dari enam masjid yang diukur yaitu Masjid Besar An-Nuur, Masjid Al Furqon, dan Masjid Al Hurriyyah sudah memenuhi standar baku mutu tingkat kebisingan. Ketersediaan RTH pada keenam masjid dengan luas rata-rata sebesar 273.558,19 m2., Mosques as public facilities to meet the needs of worship must provide peace and tranquillity to visitors and their environment. This study was conducted to determine comfort in the mosque space based on thermal comfort, visual comfort, and audial comfort. The research was conducted using a qualitative method in filling out questionnaires by respondents and a quantitative method based on the measurement of three parameters at the research site. Research on the six mosques in the Bogor area gave an average air temperature of 26,2°C; relative humidity of the air by 82,6%; lighting intensity of 228 lux; and a noise level of 47 dB(A). Air temperatures that meet quality standards are found in the Great Mosque of An-Nuur and Al Hurriyyah Mosque. The relative humidity of the air in the six mosques did not meet the quality standards. The intensity of lighting at the six mosques measured did not meet quality standards. Three of the six mosques measured, namely the Great An-Nuur Mosque, Al-Furqon Mosque, and Al Hurriyyah Mosque, have met the noise level quality standards. The availability of green open space in the six mosques with an average area of 273.558,19 m2.

Judul: Enteric Collibacillosis Pada Anak Babi Baru Lahir: Patogenesa dan Perubahan-Perubahan Patologisnya
Abstrak: Diare disebabkan oleh infeksi bakteri Escherichia coli pada anak-anak babi baru lahir yang peka terhadap en terotoksin produk bakteri tersebut. Dikenal sebagai colibacillosis. Patogenesa dari colibacillosis anak babi baru lahir adalah (1) infeksi oleh E. coli patogen, (2) proliferasi E. coli di lumen usus halus, (3) produksi dan pelepasan enterotoksin, dan (4) aktifitas toksin pada usus halus. Dalam proses proliferasi, adanya antigen pili K88 sangat penting karena memungkinkan bakteri perlekatan dengan epitel mucosa usus halus. mengadakan Setelah ko lonisasi dan proliferasi segera toksin dilepaskan. Akti- fitas toksin menginduksi sekresi yang berlebihan dari u- sus sehingga banyak cairan yang dikeluarkan ke lumen usus. Hal ini mengakibatkan banyak cairan dan elektrolit hilang sehingga timbul diare, dehidrasi dan asidosis yang sering menyebabkan kematian. Perubahan-perubahan patologis yang umum adalah dis tensi usus halus, dilatasi lambung dan infark pada kurva- tura mayor. Perubahan-perubahan histologis yang terjadi adalah enteritis hemorrhagica acuta, oedem dan kongesti pembuluh darah di lamina propria, akumulassi leukosit inti polimorf, sel monosit, dan inti sel mengalami piknosis Thrombus pada vena dan degenerasi serta desquamasi sel epitel usus….
