Abstract

AbstractThe objectives of the study were: (1) to describe the steps in implementing Project Based Learning (PjBL) model in improving mathematics learning outcomes about distance, time, and speed, (2) to increase mathematics learning outcomes about distance, time and speed by applying Project Based Learning (PjBL), and (3) to describe the constraints and solutions in implementing Project Based Learning (PjBL) model in improving mathematics learning outcomes about distance, time, and speed. The research was collaborative classroom action research conducted in three cycles. The subjects were students and teacher of fifth grade SDN Kledungkradenan. The data were qualitative and quantitative data. Data collection techniques used observation, interviews, and tests. The data validity used triangulation of techniques and triangulation of sources. Quantitative and qualitative data analysis included data reduction, presentation, and conclusion. The results showed that: (1) the steps in the implementation of Project Based Learning (PjBL) model were: (a) presenting problems, (b) preparing project plans, (c) preparing project activity schedules, (d) monitoring project implementation, (e) presenting project results, (f) evaluating project results; (2) the application of Project Based Learning (PjBL) model improved mathematics learning outcomes about distance, time and speed; (3) the constrains were: some students were passive in project activities and did not get enough tools needed in making projects while the solutions were: the teacher monitored the learning and discussion activities, the teacher encouraged the students to participate actively in project activities, and the teacher and the students prepared the tools and materials needed in learning

Abstract

Global temperatures and changes in extreme weather patterns require special attention to building facade design as an effort to mitigate and adapt to climate change. Inappropriate facade design can lead to high energy consumption for cooling and heating, as well as increase carbon emissions from the use of this energy. The importance of this innovation is increasingly urgent given the projected increase in urban population and the need for comfortable and energy-efficient buildings in the future. One concrete step in overcoming this challenge is to implement a facade design that is adaptive to the climate and efficient in energy use. This study will analyze the complex in Serpong Garden as a case study to see how facade design can be optimized for climate adaptation. The housing is located in Serpong Garden which is geographically located at 6 '0 - 6 '20 South Latitude and 106 '20- 106 '43 East Longitude which is in a tropical and humid climate. The focus of this study is to meet the conditions of thermal comfort which are influenced by heat radiation, temperature, humidity and air/wind movement. Based on the analysis of the measurement results, it can be concluded that the design of the modern house facade is not optimal in creating thermal comfort conditions inside the room.
