PERKUATAN KOLOM LANGSING BETON BERTULANG DENGAN FIBER GLASS JACKET PADA KONDISI KERUNTUHAN TARIK
Kolom beton bertulang merupakan komponen penting dari struktur
bangunan dari beton. Kolom menjadi komponen penting karena apabila kolom
mengalami kegagalan dapat mengakibatkan runtuhnya komponen struktur yang
lain. Kegagalan ini juga dapat dicegah dengan perkuatan-perkuatan pada kolom.
Salah satu metode perkuatan pada kolom adalah metode jacketing menggunakan
FRP. Ada 3 jenis FRP yaitu GRFP (Glass Fiber Reinforced Polymer), AFRP
(Aramid Fiber Reinforced Polymer), dan CFRP (Carbon Fiber Reinforced
Polymer). Pada penelitian ini penulis akan meneliti beban aksial maksimum dan
persentase kenaikan beban aksimal maksimum pada kolom langsing yang
menggunakan Fiber Glass tipe woven roving yang biasanya digunakan pada
tendon air sebagai pengganti GRFP.
Penelitian ini menggunakan kolom langsing beton bertulang dengan
ukuran 120 mm x 120 mm x 1700 mm dengan panjang bersih kolom adalah 1300
mm dan panjang kaki tumpuan 200 mm. Adapun tulangan longitudinal kolom
terbuat dari baja dengan diameter 8 mm dengan jumlah 4 tulangan longitudinal
dan sengkang diameter 6 mm dengan jarak antar sengkang 50 mm di panjang
bersih kolom dan 25 mm di kaki tumpuan. Kolom langsing beton bertulangan ini
ditinjau kekuatannya dalam menahan beban tekan aksial eksentris pada kondisi
keruntuhan tarik. Kolom terdiri dari 2 kolom normal dan 2 kolom dengan 3 lapis
fiber glass untuk masing-masing eksentrisitas 70 mm dan 90 mm.
Berdasarkan pengujian di laboratorium diperoleh kolom normal dengan
eksentrisitas 70 mm menerima beban maksimum rata-rata 7.7195 ton dan kolom
fiberglass dengan eksentrisitas 70 mm menerima beban maksimum rata-rata
sebesar 11.389. Dapat diketahui bahwa adanya peningkatan beban sebesar
32.2197 %. Sedang pada kolom normal dengan eksentrisitas 90 mm menerima
beban maksimum rata-rata sebesar 4.717 ton sedangkan kolom dengan fiberglass
menerima beban sebesar 7.7195 ton. Dari data tersebut dapat diketahui bahwa
adanya peningkatan beban sebesar 38.8950 %

An Early Detection Method of Type-2 Diabetes Mellitus in Public Hospital
Diabetes is a chronic disease and major problem of morbidity and mortality in developing countries. The International Diabetes Federation estimates that 285 million people around the world have diabetes. This total is expected to rise to 438 million within 20 years. Type-2 diabetes mellitus (T2DM) is the most common type of diabetes and accounts for 90-95% of all diabetes. Detection of T2DM from various factors or symptoms became an issue which was not free from false presumptions accompanied by unpredictable effects. According to this context, data mining and machine learning could be used as an alternative way help us in knowledge discovery from data. We applied several learning methods, such as instance based learners, naive bayes, decision tree, support vector machines, and boosted algorithm acquire information from historical data of patient’s medical records of Mohammad Hoesin public hospital in Southern Sumatera. Rules are extracted from Decision tree to offer decision-making support through early detection of T2DM for clinicians.
unreinforced masonry buildings
A recent earthquake of M=4.9 occurred on 29 October 2007 in C, ameli, Denizli, which is located in a seismically active region at southwest Anatolia, Turkey. It has caused extensive damages at unreinforced masonry buildings like many other cases observed in Turkey during other previous earthquakes. Most of the damaged structures were non-engineered, seismically deficient, unreinforced masonry buildings. This paper presents a site survey of these damaged buildings. In addition to typical masonry damages, some infrequent, event-specific damages were also observed. Reasons for the relatively wide spread damages considering the magnitude of the event are discussed in the paper
