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: Analisis Kenyamanan Ruang Menggunakan Simulasi Software Ecotect Analysis pada Masjid Kawasan Kecamatan Bogor Tengah Kota Bogor
Abstrak: Indonesia berada di iklim tropis lembab, yang menyebabkan suhu cenderung tinggi dan kecepatan angin rendah. Keadaan ini berpengaruh pada tidak tercapainya kenyamanan ruang dalam masjid. Kenyamanan ruangan dapat meningkatkan kondisi kesehatan, kenyamanan, dan produktivitas seseorang. Tujuan penelitian ini adalah menentukan tingkat kenyamanan ruang lima masjid yang berada di Kawasan kecamatan Bogor Tengah Kota Bogor dan melakukan simulasi modifikasi menggunakan Software Ecotect Analysis. Penelitian ini dilakukan dengab pengukuran langsung di lapangan yang meliputi pengukuran suhu dan kelembapan, intensitas cahaya, dan kebisingan kemudian dilakukan modifikasi menggunakan Software Ecotect Analysis. Terdapat lima masjid yang belum memenuhi kriteria kenyamanan termal dan audial, serta terdapat tiga masjid yang belum memenuhi kenyamanan visual. Modifikasi menggunakan Timber Clad Masonry (pasangan batu bata berplaster dengan lapisan kayu) dan Concrete Block Plaster (dinding berbahan beton dengan plaster). Hasil modifikasi terbaik terdapat pada Masjid Agung dengan modifikasi 2 terjadi penurunan sebesar MRT 21,9%, penurunan menurunkan PPD sebesar 75%, meredam arah suara sebesar 49,9% dan meningkatkan pencahayan sebesar 297%., Indonesia is in a humid tropical climate, which causes temperatures to tend to be high and wind speeds to be low. This situation has an effect on not achieving the comfort of space in the mosque. Room comfort can improve a person's health, comfort, and productivity. The purpose of this study was to determine the comfort level of five mosque spaces located in the Bogor Tengah sub-district area of Bogor City and to simulate modifications using Ecotect Analysis Software. This research was carried out by direct measurements in the field which included measurements of temperature and humidity, light intensity, and noise then modifications were made using Ecotect Analysis Software. There are five mosques that do not meet the criteria for thermal and audial comfort, and there are three mosques that do not meet visual comfort. Modification using Timber Clad Masonry (pair of plastered bricks with layers of wood) and Concrete Block Plaster (walls made of concrete with plaster). The best modification results were found in the Great Mosque with modification 2, there was a decrease of MRT by 21.9%, a decrease in PPD by 75%, muffled sound direction by 49.9% and increased lighting by 297%.

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….
