Calcium silicate board merupakan material aplikasi untuk interior bangunan. Sekarang material ini dikembangkan untuk eksterior bangunan sehingga diharapkan tahan terhadap air dan panas matahari. Penelitian ini menggunakan 4 macam merk material berukuran 6 mm dan 8 mm, dimana dilakukan pengujian kekuatan lentur normal, pengujian kekuatan lentur dengan perlakuan air hangat, pengujian kekuatan lentur dengan perlakuan basah kering. Kualitas material dari segi durabilitas diketahui melalui pengujian panas hujan untuk mengetahui tingkat keretakan yang ditimbulkan akibat perubahan cuaca yang terjadi dan pengujian ketahanan air untuk mengetahui terjadi rembesan atau tidak. Untuk segi kenyamanan dilakukan pengujian kemampuan reduksi bunyi. Pengujian dilakukan juga dengan penambahan material lain yaitu 100% pasir lumajang,100% pasir silika, serta komposisi 50% pasir lumajang dan 50% pasir silika. Hasil penelitian menunjukkan hasil pengujian kekuatan lentur normal di kelas 2 dan 3. Sedangkan pada pengujian basah-kering dan air hangat mengalami penurunan kekuatan tetapi masih dapat memikul beban diatas 200 kg/m2 lebih dari syarat beban PPIUG 1983. Pada pengujian panas-hujan selama 40 jam tidak menimbulkan retakan pada benda uji. Pengujian ketahanan air tidak menimbulkan rembesan setelah 24 jam. Semua benda uji memiliki kemampuan reduksi bunyi yang kurang dari prasyarat SNI 7705:2011 pada semua frekuensi. Pengaruh material pengisi calsium silicate board meningkatkan kemampuan reduksi bunyi, pada frekuensi 250 Hz sebesar 400%.

Title: Inclusive Design and Service Accessibility Improvement for Various Users in Petra Christian University Library In the context of Indonesia, Act No. 8 of 2016 actually recognizes the rights of the disabled. Unfortunately, the UNCRPD implementation seems not quite effective. Many educational facilities are not accessible for the disabled or the People with Disabilities. The learning environment has an indirect impact on student achievement, creating a positive attitude, higher motivation for learning and no doubt better performance. The accessibility aspect of learning places is crucial for educational facilities such as university Library. Petra Christian University (UKP) is located in the heart of Wonocolo District, Surabaya, East Java-Indonesia. With the motto "Learning zone that cares ". Library@Petra wants to be a learning center that caters to academics, and practitioners. Library@Petra is the largest and most complete academic library in East Java. On the other hand, many users find accessibility barriers to Library@Petra-owned facilities built in the 1980 's. Accessibility issues for all users are generated from Focus Group discussion (FGD) discussions, involving people with disabilities, elderly, pregnant women following children in accordance with User – Centered Principle. The Library@Petra redesign was submitted based on the principles of inclusive design submitted by Tanuwidjaja (2015). An Equitable Use but Reasonable Principle will be met through providing a help corner for users with special needs, accessible pathways and space to spin, as well as accessible meeting and toilet areas. Simple and Intuitive Use Principle will be filled with braille/visual and directional guides for the blind and other. The principle of requiring Low Physical Effort applied to accessible toilets and assistance to retrieve books in specific areas that are hard to reach, computers for users with special needs (blind users) are provided for reading, to access e-books and catalogs. Prohibition of Usage Error is recommended with the installation of a fence as high as 150 cm around the elevator aisle and anti-slippery floor. These recommendations were found difficult to be addressed because of the limited university's budget and the use of active Library@Petra throughout the year. Therefore, it is proposed a Special Assistance Corner for special users including disability as a first step. This corner is equipped with a dedicated User Service desk, a waiting couch and three computer stations for visual disabilities to read ebook and catalogue sites. Recommendation of this case is the higher nvolvement of People with Disabilites in inclusive design.

Bangunan publik seperti sekolah adalah tempat bagi anak-anak untuk tumbuh, melakukan beberapa kegiatan, dan berinteraksi dengan yang lain. Lingkungan belajar yang baik dapat mengoptimalkan pertumbuhan anak. TK AN-NUR adalah salah satu sekolah di Surabaya yang belum mengoptimalkan fasilitas sekolahnya. Ini adalah alasan mengapa penulis memilih topik ini untuk menganalisis apa yang harus diperbaiki untuk membuatnya lebih baik. Oleh karena itu, penulis menyarankan untuk memperbaiki dan menambahkan beberapa elemen untuk meningkatkan kenyamanan belajar dan bermain untuk lingkungan anak-anak di sekolah itu

This research aimed to find out how lighting influence visual task performance of the elderly.The experiment was done on the table with different lamp position and by giving mark on the landolt ring chart printed on different reading media. Three position, the front, the middle and the back were the variables for lamp position, whilst different reading medias were the brown paper usually used for newspaper, the white silk uncoated paper or ‘HVS’ paper and the white gloss paper. The lamp were TL5 LED with 4000 °K and 6500 °K color temperature. The illumination level maintained specificly at 250-325 lux range. The respondents were 12 elderly with 58 years as the mean age. The result findings, for newspaper, the best position for speed was the front with 1.15 second per stroke; followed by the back with 1.18 second per stroke; and the middle got the lowest result with 1.4 second per stroke. For the HVS and glossy paper with higher luminance, the best for speed was the middle position that was the darkest in illumination, with 1.25 second per stroke for HVS and 1.3 second per stroke for glossy. The worst result was the back with 1.4 second per stroke for HVS and 1.36 second per stroke for glossy paper. For accuracy, the best for newspaper was the front, 96.02%. For the HVS paper, the middle and the back position has got the same highest accuracy, 90.45%. For the glossy paper, the middle position has got the highest accuracy, 91.62%. The visual task performance result, for the newspaper, the front position has got the highest score, followed by the back position that have brighter in illumination, but the score was lowest for the middle position. Contrary, for white HVS and white gloss paper, which get almost identic result, the middle position which was rather dark in illumination was the best, while the front and the back position were worse in visual task performance score. So that can be concluded that the higher illumination level was not always give the best to visual task performance; but depending to the user and the kind of paper or reading media as well.

This research aimed to find the influence of vegetation outside the window to indoor light and thermal in Design studio, Architecture department of Petra Christian University, Surabaya. The vegetation was Shibataea kumasasa, cultivated in planter boxes, 90-100 centimeter high. The data was collected from the West and North window, for condition with and without vegetation outside the window. The measurement was taken on March until May 2019, using Hobo U12-012 data logger for measuring air temperature (°C), relative humidity (%) and illuminance (lux). Beside those physical measurement, the perception of 89 students as building user was also taken. The measurement result from windows facing West and North with the vegetation, the lowest indoor air temperature was 27°C with an average relative humidity of 70%. Meant it's at the upper edge of the comfort zoneof Bioclimatic Chart from Olgyay and Canada’s National Occupational Health & Safety Resource (CCOHS), so the indoor space was still uncomfortable and cooling was required to get into the comfort zone at warm humid climate. Result from lighting measurements obtained for west-oriented windows with vegetation outside the window, the highest illuminance was 350 lux at 02:45 pm, as well as for windows facing North at 07.30 am - 04.45 pm in range of 105 - 155 lux (highest). So, if there are vegetation outside windows, it will require electric lighting addition, because the illuminance are below the SNI 03-6197-2011which recommends 750 lux for design studio. Whilst the user respond from the questionnaire taken, stated that aesthetic vegetation was expected for natural element, blocked the penetration of solar radiation into indoor, and reduce glare to increase visual comfort without reducing luminous sufficiency for the visual activities in the design studio.
