<![CDATA[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.]]>

<![CDATA[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.]]>

<![CDATA[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.]]>

<![CDATA[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.]]>

<![CDATA[In flood-prone areas, coordination between parties in disaster risk reduction (DRR) activities is very important. This is because the consequences of disasters will directly affect the disruption of people's lives and livelihoods, and also hinder the process of sustainable development. The study aims to develop a public coordinating scheme for disaster risk reduction (DRR) activities based on public resources in Gorontalo Regency. Public resources from government agencies and society are available in Gorontalo Regency with their respective tasks at the stages before, during and after the disaster. Public coordination is expected to support the implementation of DRR-based sustainable development in Gorontalo Regency. The preparation of public coordination scheme begins with geospatial flood hazard assessment based on the characteristics of the Limboto Watershed using a Geographic Information System (GIS) tool. The result provides a basis for the implementation of public coordination arrangements for DRR. Gorontalo Regency is dominated by a coastal land parcel adjacent to Tomini Bay, stretching from lowland plains to hilly mountains. High rainfall, critical land use and settlements in the lowlands have caused the study area categorized into high- to very high-risk zones of flooding. To ensure sustainable development runs effectively, its implementation must be based on DRR policy with public coordination. Public coordination is carried out between government agencies and society, who cooperate in compliance with their respective roles and tasks at the stage before, during and after the disaster. The results show that the involvement of more sectoral parties is needed at the stage before and during the disaster. This indicates that public coordination before the disaster performs risk prevention and reduction activity that should be prioritized in the implementation of development before inhibiting its sustainability.]]>

<![CDATA[Bencana alam geologi setiap saat bisa datang seketika menghancurkan. Bencana ini akan menyebabkan kerusakan yang lebih besar dan fasilitas penduduk ketika tidak dikontrol dengan tepat waktu dan dilakukan mitigasi. Upaya awal dilakukan didalam mengantisipasi terjadinya bencana geologi yaitu persiapan, inventarisasi jenis bencana dan menentukan lokasi-lokasi yang lebih berbahaya. Daerah studi memiliki banyak fitur yang harus ditandai sebagai tanah longsor karena daerah tersebut memiliki lereng yang terjal, tingkat pelapukan batuan yang tinggi, batuan yang retak-retak dan mudah lepas, termasuk jalur sesar/patahan/gawir, lereng terpotong jalan dan adanya rutinitas getaran kendaraan yang penuh muatan. Sedangkan akibatnya telah merusak saluran drainase dan mengancam jiwa manusia maupun kendaraan yang rutin melewati jalan. Beberapa hal yang harus dilakukan secara mandiri oleh masyarakat adalah peningkatan kewaspadaan saat musim hujan dan tindakan penutupan rekahan di permukaan tanah, serta konservasi tanah (stabilisasi dan perlindungan lereng). Meningkatnya vegetasi, konstruksi dinding penahan dan struktur lain yang dapat mengurangi resiko tanah longsor di sepanjang tepi jalan sehingga dapat membantu dalam pencegahan tanah longsor di daerah tersebut.]]>

<![CDATA[Geological structures in the form of joints and faults have big role in landslide disaster. This study aims to analyze the geological structures using stereographic analysis and rosette diagrams and determine the potential landslides that can occur in the research location in order to identify landslide mitigation efforts in the research area. The method used in this research is field observations then followed by stereographic analysis and rosette diagrams, which are one of the diagrams of the presentation of orientation of the geological structures elements. The results showed that the mechanism of landslide mostly caused by the geological structures distribution in the Tanjung Keramat area, especially by joint distribution. Tension joints dominant direction relatively west as well as the slope direction. Stereographic analysis of the shear joints show the type of extensional stress directing relatively North-South. Potential types of landslide that can occur are wedge failures. Appropriate mitigation efforts are by reducing the slope angle and making structural retaining walls to withstand natural slopes and heaps high enough.]]>
