Abstract

Universitas Muhammadiyah Gorontalo (UMGo) yang berdiri sejak tahun 2008 merupakan salah satu Amal Usaha Muhammadiyah (AUM) yang salah satu tujuannya adalah untuk pengembangan dan pendidikan generasi muda Indonesia. Kelengkapan sarana dan prasarana perkuliahan merupakan suatu hal yang harus dipenuhi demi terciptanya proses pendidikan dan keberlanjutannya. Ketersediaan kebutuhan Ruang Terbuka Hijau (RTH) di Kampus UMGo sangat dibutuhkan bagi sivitas akademik UMGo karena fungsi dan peranannya sebagai paru-paru kampus dan dapat meminimalisir perubahan iklim serta memberikan kontribusi positif bagi AUM lainnya. Tujuan penelitian ini adalah untuk mengkaji ketersediaan RTH Kampus UMGo menggunakan foto udara drone. Metode penelitian menggunakan metode deskriptif kuantitatif menggunakan citra foto udara yang direkam menggunakan drone kemudian dianalisis dengan teknologi Sistem Informasi Geografis (SIG). Hasil penelitian menunjukkan bahwa ketersedian RTH di Kampus UMGo telah memenuhi syarat yang ditetapkan Undang-Undang No. 26 tahun 2007 tentang Penataan Ruang.

Abstract

One of the coastal areas including the mangrove forest, storing great potential to be used sustainably in addition to its function also as a carbon stock storage. Mangrove forests become one of the attractions to be used as an ecotourism area accompanied by local cultural concepts. This study aims to geographically analyze the "Tracking Mangrove in Love" (TMiL) Langge Village, North Gorontalo District. Mangrove Restoration and Learning Center (PRPM) Center. The research method used is terrestrial observation, observation and analysis of multitemporal google earth imagery (2003-2018). The DJI Phantom 4 unmanned vehicle that serves to photograph the TMiL ecotourism area was used as a tool in this study. The multitemporal Google Earth Imagery (2003-2018) functions to observe changes in mangrove forest land cover before and after PRPM TMiL is opened to the public. Drones that are flown on autopilot are operated using an android smartphone that has the Pix4D Capture application installed. Aerial photographs produced from drone recordings are then processed into orthomosaic using Pix4Dmapper Pro software. Orthomosaic data is then used for current land use analysis and compared with multitemporal data from Google Earth imagery. The environment around the ecotourism area was also observed, such as conditions, human activities, and current land use. The results showed that PRPM TMiL did not highlight its function as an ecotourism area as the understanding stated in Permendagri No.33 Year 2009.Kawasan pesisir yang salah satu termasuk didalamnya yaitu hutan mangrove, menyimpan potensi besar untuk dapat dimanfaatkan secara berkelanjutan selain fungsinya juga sebagai penyimpan stok karbon. Hutan mangrove menjadi salah satu daya tarik untuk dijadikan sebagai kawasan wisata yang disertai konsep budaya lokal. Penelitian ini bertujuan untuk menganalisis secara geografis Pusat Restorasi dan Pembelajaran Mangrove (PRPM) “Tracking Mangrove in Love” (TMiL) Desa Langge, Kabupaten Gorontalo Utara. Metode penelitian yang digunakan yaitu pengamatan secara terestrial, pengamatan dan analisis dari citra google earth multitemporal (2003-2018). Wahana tanpa awak DJI Phantom 4 yang berfungsi untuk memotret kawasan ekowisata TMiL digunakan sebagai alat dalam penelitian ini. Citra Google Earth multitemporal (2003-2018) berfungsi untuk mengamati perubahan tutupan lahan hutan mangrove sebelum dan sesudah PRPM TMiL dibuka untuk umum. Drone yang diterbangkan secara autopilot dioperasikan menggunakan smartphone android yang telah terinstal aplikasi Pix4D Capture. Foto udara yang dihasilkan dari perekaman drone kemudian diolah menjadi orthomosaic menggunakan perangkat lunak Pix4Dmapper Pro. Data orthomosaic selanjutnya digunakan untuk analisis kondisi PRPM TMiL terkini lalu dibandingkan dengan data multitemporal dari citra google earth. Dilakukan pula pengamatan lingkungan sekitar kawasan wisata seperti kondisi, aktivitas manusia, dan penggunaan lahan sekitarnya. Hasil penelitian menunjukkan bahwa PRPM TMiL tidak menonjolkan fungsinya sebagai kawasan ekowisata seperti pengertian yang tercantum dalam Permendagri No.33 Tahun 2009.

Abstract

Renewable energy had been monopolized the research area in these past decade up till nowadays, due to its reliability and future in global production of electrical and thermal energy. Narrowing down the scope to the photovoltaic thermal (PVT) system, lots of improvements had been implied both theoretically and experimentally. One of the most attractive applications of PVT water or air-based collectors is building integrated photovoltaic thermal (BIPVT) system, which has undergone rapid developments in recent years. This review paper comprises the research findings on the improvements that had been integrated by PVT systems as well as well as personal and cited remarks on advancements on cooling techniques on PVT system.

Abstract

Photovoltaic thermal (PVT) collectors directly convert solar radiation into electrical and thermal energy. A PVT collector combines the functions of a PV panel and a flat plate solar collector. The development of PVT air collectors is a very promising research area. At present, PVT air collectors are used in solar drying and solar air heaters. On the basis of existing literature, most PVT air collectors were built by using monofacial PV modules. The bifacial PV modules had two active surfaces that could capture solar radiation with its front and rear surfaces. Additional sunlight absorption through both surfaces resulted in an enhanced electrical power generation compared with the conventional monofacial PV. Therefore, bifacial PVT was considered to be useful and attractive due to its potential of enhancing overall system performances, including energy and exergy efficiencies. Findings of this review indicated that PVT air collector with bifacial solar cell produced a larger amount of electrical energy, which was approximately 40% higher than a monofacial PVT. The energy and exergy efficiencies of PVT air collector with monofacial solar cells range from 27% to 94% and from 4% to 18%, respectively. For bifacial PVT, the energy and exergy efficiencies of PVT air collector range from 28% to 67% and from 8.2% to 8.4%, respectively.

Abstract

Conventional fuels are not free, scarce and expensive, and its future cost and availability are uncertain. Hence, the usage of solar energy in applications will probably increase and further become economically feasible in the near future. Solar energy is free, clean, and renewable and has been widely used in electricity generation and thermal energy via photovoltaic thermal (PVT) system. PVT is a hybrid system consists of a PV panel and a solar collector in a single unit to simultaneously produce electricity and thermal energy. In this review, energy and exergy efficiency for water-based PVT systems is presented. As conclusion, the study on exergy is still limited and is recommended to be furthered in order to obtained useful energy generation by the system.

Abstract

Over recent years the photovoltaic technology has obtained significant development, especially in building integrated photovoltaic thermal (BIPVT) system. Photovoltaic thermal (PVT) air collectors are advantageous because of their efficiency. Various studies have been conducted to determine the ideal parameters of PVT air collectors. Few theoretical approach models of PVT air collector systems were used to help detect occurrences in a PVT collector system and calculate the optimal parameters. The heat transfer and energy balance of PVT air collectors were analysed and reviewed based on the model, quantity of cover, channels and forms of the collector. A mathematical model was developed to describe actual working situations and to examine new shut PVT collectors. The first law of thermodynamics is the principal equation in the model. Different analysis methods were utilised to evaluate PVT performances, which are generally based on energy and exergy analyses. This review focuses on theoretical approach model of single-pass PVT air collector.
