<![CDATA[Saat ini, aspek penghijauan di kota-kota besar mulai diperhatikan. Permasalahan lingkungan perkotaan akibat adanya Urban Heat Island (UHI) menjadi latar belakang dari pemilik bangunan untuk mengaplikasikan konsep vertical garden pada bangunan mereka. Kemampuan vertical garden dalam menurunkan profil suhu permukaan dinding merupakan salah satu aspek dasar untuk menciptakan kenyamanan termal bagi penggunanya. Penelitian ini merupakan hasil studi dari pengaruh vertical garden terhadap kondisi termal bangunan PT. Pertamina Semarang. Profil suhu permukaan dinding interior ruangan bervertical garden lebih rendah bila dibandingkan dengan ruangan non vertical garden. Rata-rata selisih profil suhunya adalah 1.4C-2.1C. Selisih minimum terjadi pada awal pengukuran sedangkan selisih maksimum terjadi pada akhir pengukuran dengan sebaran suhunya semakin ke atas profil suhunya semakin panas. Dari hasil studi juga diketahui bahwa vertical garden mampu menurunkan suhu permukaan dinding non vertical garden yang berada pada satu area dengan dinding bervertical garden]]>

<![CDATA[Profil gerakan udara yang masuk dalam bangunan disebabkan banyak faktor element arsitektur, diantaranya adalah bentuk jendelanya. Pengamatan terkait ini telah banyak dilakukan, baik yang dilakukan secra manual di lapangan ataupun dilakukan dengan simulasi CFD. Keakurasian suatu program simulasi dapat dibandingkan hasil pengukurannya dengan hasil pengamatan lapangan. Pada tulisan ini memiliki dua tujuan, pertama, yaitu menvalidasi dan mengetahui tingkat keakuratan beberapa teknik pengamatan penelitian in-situ (obyek pemodelan dan obyek ruangan skala 1:1 dan pensimulasian dari program komputasi CFD Ecotect. Dan tujuan kedua adalah mengetahui effek bukaan jendela jungkit yang dilakukan dengan dua metode tersebut terhadap tingkat kecepatan udaradidalamnya. Hasilnya dari pengamatan ini menunjukan bahwa bahwa skala keakuratan alat ukur seharusnya diperbandingkan dengan tingkat kalibrasi tertentu dari suatu program simulasi. Sedangkan terkait aplikasi model bukaan jendela, ternyata pilihan jendela jungkit sudut 30 lebih direkomendasikan dari pada sudut 45.]]>

<![CDATA[Saint Peter Church Sambiroto located in the Semarang City which has tropical climate. The building has many openings like doors and bouvenlights. Currently in the east corridor are given tents to accommodate the number of congregations that exist, and on the east side the hallway is paired with banner to protect the east hallway from sun’s heat. The researcher will examine how openings play a role in creating thermal conditions in buildings. This research method uses field measurement techniques in the church regarding dry temperature, relative humidity and air movement in the church at each worship time in the morning and evening and at point where there are openings and not. After doing research, it was found that the temperature in the morning was still in a comfortable condition but at the evening temperature was above comfortable conditions. Even though all measuring points are affected by fan, the point where has opening has low temperature than where has no opening, in the point where has banner have higher temperature than no banner. This proves that openings play a role in flowing air into the building and banners blocking the air to entering lobby and building area from the east side.]]>

<![CDATA[Teknologi diagnostik medis yang digunakan pada unit radiologi di rumah sakit sudahcenderung bergeser dari teknologi analog berbasis film menjadi teknologi digital (filmless). Salahsatu cara membuat system radiografi tanpa film adalah dengan cara konversi digital menggunakantabung kedap cahaya (light tight tube). Dalam penelitian ini, kami telah mengkaji kemungkinanpemanfaatan sistem pencitraan radiografi digital sinar-x berbasis X-Ray Intensifying Screen(XRIS) dihubungkan dengan perangkat frame-grabber. Hasil eksperimen tahap awal untukmemperoleh radiograf tulang tangan menunjukkan bahwa sistem ini cukup dioperasikan padategangan anode-katode 50 kV, arus waktu filamen 50 mAs dan waktu paparan 0,1 detik untukmenghasilkan citra yang cukup dapat dilihat. Untuk sekali paparan, dimungkinkan memperolehbeberapa citra untuk obyek yang sama pada posisi tetap, tipa-tiap citra mengandung informasiradiografi berbeda ditunjukkan oleh distribusi tiap citra yang bervariasi. Hasil ini menunjukkanbahwa sistem ini diharapkan lebih efisien dan lebih efektif dibandingkan dengan metodekonvensional berbasis film, dan dapat dikembangkan untuk diagnose mineral tulang.Kata kunci: radiografi digital; filmless; sinar-x; tulang tangan]]>

<![CDATA[AbstractIn this research, we report the quality of several cooking oils before and after heating. The parameter of quality was based on electrooptics characteristic or, so called, the change ofpolarization angle induced by external electric field. In this examination, it was used threedifferent brands of cooking oils. The samples were heated in the time interval between 0-120minutes. The electrooptics characteristic was determined by measuring the change ofpolarization angle of light as it passed through the oil while it was applied by external electricfield. The field was produced by two parallel plates connected to different potential between 0-9kV. The light source was diode laser atλ = 650 nm and λ = 532 nm. The quality of oil was then determined by average polarization angle per potential difference, i.e. α ≡ Δθ/ΔV. Based on the result of observation, the fresh oil before heated has smaller change of polarization angle thanoil after heated, which is in agreement to the previous study. The longer heating time is, morefree radicals are produced, which leads to higher polarization. It shows also that the change ofpolarization depends on the wavelength.  From two diode lasers, the effective wavelength toproduce higher number free radicals is obtained by 532 nm. The increasing average ofpolarization angle is linearly to the increasing of heating time. It is obvious that the electroopticsparameter could be proposed as an alternative quality test of cooking oil.Keyword: Cooking oil quality, Change of polarization angle, electrooptics]]>
