"A House in the Sun describes experiments in solar house heating in American architectural, engineering, political, economic, and corporate contexts from the beginning of World War II until the late 1950s. Solar houses were built across the United States, and also proposed for sites in India, South Africa, and Morocco. These experiments developed parallel to transformations in the discussion of modern architecture, relying on new materials and design ideas for both energy efficiency and claims to cultural relevance. These experiments also developed as part of a wider analysis of the globe as an interconnected geophysical system. Perceived resource limitations in the immediate postwar period led to new understandings of the relationships among energy, technology, and economy. The solar house, both as a charged object in the milieu of suburban expansion, and as a means to raise the standard of living in developing economies, became an important site for social, technological, and design experimentation. A House in the Sun argues that this mid-century solar discourse was one of the first episodes in which resource limitations were seen as an opportunity for design to attain new relevance. Furthermore, discussion of and experimentation in solar technology established both an intellectual framework and a funding structure for the articulation of global environmental concerns in subsequent decades. In presenting evidence of resource tensions at the beginning of the Cold War, the book presents a new perspective on the histories of architecture, technology, and environmentalism, one more fully engaged with geopolitical and geophysical pressures."

"Penelitian ini didasarkan kebutuhan data intensitas radiasi matahari yang mendorong penggunaan sensor pyranometer yang semakin tinggi. Dalam rangka meningkatkan efisiensi kalibrasi pyranometer, perlu dikembangkan metode kalibrasi yang lebih efisien. Salah satu metode yang mampu memenuhi kebutuhan efektivitas kalibrasi pyranometer adalah Continous Sun Shade Method (CoSSM). Tujuan penelitian ini adalah menemukan teknik kalibrasi terbaik sebagai acuan metode kalibrasi pyranometer di Jakarta. Penelitian ini dilakukan di gedung BMKG Kemayoran Jakarta dari tanggal 9 Desember 2022 hingga 5 Februari 2023. Empat unit pyranometer UUT GHI, satu pyrheliometer (DNI), dan satu pyranometer standar dengan pembayang (DHI) digunakan dalam penelitian ini. Peneliti mengkombinasikan tiga faktor yaitu perbedaan jeda dengan 30, 60, dan 120 detik, data set dengan 10, 15, dan 20 data, serta data seri dengan 10, 15, dan 20 data. Data yang diperoleh kemudian dilakukan tiga tahapan filtrasi menggunakan python dan perhitungan manual. Nilai responsivitas yang dihasilkan kemudian dibandingkan dengan responsivitas kalibrasi di dalam ruangan yang terakreditasi menggunakan Mean Bias Difference . Hasil pengolahan data kalibrasi seharusnya menghasilkan 27 nilai responsivitas, namun hanya 16 teknik yang menghasilkan responsivitas karena kurangnya data akibat filtrasi. Hasil penelitian menunjukkan bahwa teknik dengan jeda 1 menit, 10 data set, dan 20 data seri menghasilkan nilai responsivitas dengan nilai RMSE paling kecil, 0,46. Oleh karena itu, teknik tersebut dapat dijadikan prototipe sistem kalibrasi CoSSM di luar ruangan di Jakarta.

This research is based on the need for solar radiation intensity data, which has led to an increasing utilization of pyranometer sensors. In order to enhance the efficiency of pyranometer calibration, it is necessary to develop more efficient calibration methods. One of the methods capable of meeting the effectiveness requirements of pyranometer calibration is the Continuous Sun Shade Method (CoSSM). The objective of this study is to identify the best calibration technique as a reference for pyranometer calibration methods in Jakarta. The research was conducted at the BMKG Kemayoran Building in Jakarta from December 9, 2022, to February 5, 2023. Four units of UUT GHI pyranometers, one pyrheliometer (DNI), and one standard pyranometer with shading (DHI) were used in this study. The researcher combined three factors: time interval differences of 30, 60, and 120 seconds, data sets of 10, 15, and 20, and data series of 10, 15, and 20. The obtained data underwent three stages of filtration using Python and manual calculations. The resulting responsiveness values were then compared to the responsiveness of accredited indoor calibration using the Mean Bias Difference method. The calibration data processing was expected to yield 27 responsiveness values, but only 16 techniques produced responsiveness due to data loss caused by filtration. The research results show that the technique with a 1-minute interval, 10 data sets, and 20 data series yields responsivity values with the smallest RMSE value of 0.46. Therefore, this technique can be used as a prototype for the CoSSM outdoor calibration system in Jakarta."

"Pada saat ini solar cell sudah banyak digunakan dalam kehidupan sehari-hari. Solar cell yang terpasang kebanyakan bersifat statis. Hal ini mengakibatkan penyerapan energi matahari oleh solar cell kurang optimal. Agar penyerapan energi matahari oleh solar cell optimal, maka solar cell harus mempunyai system yang selalu mengikuti arah matahari. Skripsi ini membahas tentang solar tracking system yang terdiri dari solar tracker. Solar tracking system yang dibuat merupakan prototype. Solar tracker berfungsi untuk mengoptimalkan penerimaan energi matahari oleh solar cell.
Hasil pengujian yang diperoleh yaitu solar tracker yang dibuat belum berfungsi dengan baik karena kesalahan penempatan posisi LDR dan sudut ideal untuk penempatan LDR terhadap garis normal adalah 41.85°. Dari hasil tersebut disarankan bahwa untuk program lebih lanjut penempatan LDR pada sudut 41.85°, dimensi papan solar cell dicari yang ideal dan adanya solar charging."
