Abstract

Metode Box-Jenkins adalah salah satu metode yang digunakan untuk memodelkan data deret waktu dan bertujuan untuk meramalkan data pada waktu yang akan datang. Penelitian ini membahas tentang trend data kepekatan sulfur dioksida (SO2), dan menemukan model terbaik untuk data kepekatan sulfur dioksida tersebut, serta menentukan hasil peramalan pencemaran udara oleh sulfur dioksida di daerah Sukajadi Pekanbaru pada waktu yang akan datang. Data pengamatan yang digunakan adalah data rata-rata kepekatan sulfur dioksida secara harian mulai dari 01 Januari 2011 sampai 18 April 2011. Hasil analisis pada penelitian ini mendapatkan model yang sesuai untuk data sulfur dioksida yaitu model AR(3), model ini dapat digunakan untuk analisis peramalan. Hasil peramalan menunjukkan terjadinya penurunan kepekatan sulfur dioksida (SO2) dari waktu sebelumnya. Sehingga tahap kualitas udara di Sukajadi Pekanbaru untuk waktu yang akan datang dalam tahap sedang dan tidak terjadi peningkatan pencemaran udara.

Abstract

The popular solar technology is the integration of solar thermal technology and photovoltaic (PV), called photovoltaic thermal (PVT) technology. This technology converts solar energy to electrical and thermal energy. The efficiency of solar energy conversion via PVT is higher than photovoltaic and solar systems. PV cell efficiency decreases if system operating temperature is higher. Therefore, solar systems attached to PV cells act to cool PV cells and increase the overall efficiency of the PVT system. PVT construction that saves space, is suitable for domestic consumption, and long-term saving costs makes PVT current research by researchers in the latest energy technology. This review presents descriptions and previous works conducted on performances analysis of PVT water collector. Results on the performances of PVT water collectors are summarized. The energy and exergy efficiency of PVT water collector ranges from 28.5% to 85% and 6.8% to 14%, respectively.

Abstract

The most important benefit of solar energy is renewable and low pollutant source of energy (clean energy). Solar energy technology and research are developing fast and much of the technology needed for these applications in industry and agricultures is already available. Solar drying technology (SDT) is one of the most attractive and promising applications of solar energy technology. In this paper, the various performances of SDTs in Indonesia are summarized with details. Generally, the cabinet-type and tunnel-type SDTs are remarkably well suited to drying small quantities of vegetables and fruit on the household scale. Greenhouse and hybrid SDTs are suitable for use on a large scale by industries.
