Abstract

Background of this study is the low confidence eighth grade students of MTs Negeri Subah. Goals to be achieved in this study was to determine the effect of group counseling on the self-confidence of rational emotive eighth grade students of MTs Negeri Subah 2013/2014 academic year.The problems revealed in this research is how rational emotive group counseling services affect the confidence of the students? Goals to be achieved in this research is to find out how enfluence rational emotive group counseling on self-confidence eighth grade students of MTs Negeri Subah 2013/2014 academic year. The study was conducted in MTs Subah. The study population of 200 students, which is experiencing problems because confidence is taken only 10 students in the low category pretest results, and then at the interview so that the samples are 10 students, while the sampling technique using purposive sampling. The research instrument is the confidence scale that has been tested for validity and reliability.The design of this study used a quasi-experimental type of experiment with one group pre-test post-test design. The collected data were analyzed using descriptive analysis, and statistical techniques Wilcoxon sign test with a significance level of 5% The results of the analysis obtained t (55)> t table (8) with a 5% significance level, the goal of these studies has been reached, namely that the results of this study have managed to find out how enfluence Rational Emotive Group Counseling Students Against confidence Class VIII MTs Subah 2013/2014 academic year ".Keywords: Rational Emotive Group Counseling, Self-Confiden

Abstract

Kenyamanan termal di ruang luar menjadi isu yang penting saat ini akibat kenaikan yang signifikan pada suhu udara perkotaan. Kenaikan suhu ini diakibatkan oleh perubahan iklim global dan fenomena pulau panas perkotaan (Urban Heat Island) faktor pulau panas perkotaan ini dapat direduksi salah satunya dengan penghawaan pasif di ruang-ruang perkotaan. Dalam rancangan kota, penghawaan perkotaan dapat berupa pengaturan massa-massa bangunan, orientasi jalan, sampai ke detail desain bagunan yang dirancang untuk mengalirkan angin. Kota dengan penghawaan perkotaan yang baik dapat melepaskan panas yang terperangkap di antara bangunan melalui angin, juga dapat memberikan kenyamanan termal pada ruang luar. Penelitian ini bertujuan untuk mengetahui efektivitas strategi pengahawaan perkotaan dengan perletakan atap hijau di bangunan tinggi. Efektivitas ini ditinjau dari hasil simulasi Computational Fluid Dynamics (CFD) terhadap berbagai posisi perletakan atap hijau pada bangunan tinggi. Hasil simulasi didapat dari dua metode simulasi, yaitu CFD 3 dimensi pada skala kota dan CFD 2 dimensi pada urban canyon. Kedua simulasi tersebut menunjukkan bahwa atap hijau yang diletakkan pada posisi yang tepat di sebuah bangunan tinggi dapat memicu pergerakan angin yang potensial bagi reduksi pulau panas perkotaan sekaligus memberikan kenyamanan termal ruang luar di perkotaan. Kata kunci: kenyamanan termal ruang luar, pulau panas perkotaan, atap hijau, CFD  ABSTRACTCities are facing temperature increase due to global warming and urban heat island. Although the global warming needs to be solved with global acts, the urban heat island presumably can be reduced by ventilated city strategies. Ventilated cities are designed to create a preferable wind flow in the city’s spaces. Thus, it releases heat that is trapped in the urban canyon and reduces urban heat island. Wind generated by the strategy could also provide outdoor thermal comfort in the cities. One of the ventilated city strategies are by utilizing roof garden for high rise buildings. Therefore, this research is aimed to identify the effectivity of roof garden in delivering wind flow. Two computational fluid dynamics (CFD) simulation schemes had been analyzed, and this paper reviews the results. The schemes are 3D CFD simulation for urban area and 2D CFD simulation for urban canyon. Review of the result analysis shows that roof garden is potential to drive a sufficient wind flow as long as its position is appropriate. Keywords : outdoor thermal comfort, urban heat island, roof garden, CFD
