Abstrak: Pada wilayah rawan banjir, koordinasi antarpihak dalam kegiatan pengurangan risiko bencana sangat penting dilaksanakan. Hal ini dikarenakan bencana secara langsung akan berdampak pada gangguan kehidupan dan penghidupan masyarakat, juga menghambat proses pembangunan berkelanjutan. Penelitian ini bertujuan untuk menyusun skema koordinasi publik untuk kegiatan pengurangan risiko bencana (PRB) banjir berbasis sumber daya publik yang tersedia di Kabupaten Gorontalo. Sumber daya publik berasal dari instansi
pemerintah dan potensi masyarakat yang tersedia di Kabupaten Gorontalo dengan tugas masing-masing pada tahap sebelum, saat dan setelah bencana. Koordinasi publik diharapkan dapat mendukung pelaksanaan pembangunan berkelanjutan yang berbasis PRB di Kabupaten Gorontalo. Penyusunan skema koordinasi publik didahului penilaian bahaya banjir secara geospasial berdasarkan karakteristik Daerah Aliran Sungai (DAS) Limboto menggunakan perangkat Sistem Informasi Geografis (SIG). Hasil penilaian tersebut menjadi dasar
pelaksanaan penyusunan koordinasi publik untuk PRB. Kabupaten Gorontalo didominasi oleh satuan lahan pesisir yang berbatasan dengan Teluk Tomini, dataran hingga pegunungan. Curah hujan tinggi, tata guna lahan yang kritis serta permukiman yang berada di dataran rendah menyebabkan daerah penelitian termasuk pada zona risiko tinggi hingga sangat tinggi mengalami banjir. Pembangunan berkelanjutan dapat berjalan efektif apabila pelaksanaannya berbasiskan kebijakan PRB dengan koordinasi publik. Koordinasi publik dilakukan diantara instansi pemerintah dan masyarakat, yang bekerja sama sesuai peran dan tugas masing-masing pada tahap sebelum, saat hingga setelah bencana. Hasil penelitian menunjukkan bahwa dibutuhkan keterlibatan sektor yang lebih banyak pada tahap sebelum dan saat bencana. Hal ini mengindikasikan bahwa koordinasi publik sebelum terjadinya bencana merupakan kegiatan pencegahan dan pengurangan risiko yang harusnya lebih diutamakan dalam pelaksanaan pembangunan sebelum menghambat keberlanjutan pembangunan.

Abstract: 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.

Solar energy is renewable and environment friendly and has been widely used in electricity generation and thermal energy through photovoltaic thermal (PVT) system. This system is beneficial in terms of maximum energy generation and cost of usage. The growing concern on energy sources and their usage has increased the significance and demand for PVT collectors. A PVT air collector consists of a PV panel and a thermal collector system. In PVT air collector, electricity and thermal energy are generated simultaneously. This review focuses on efficiency and energy modelling for PVT air collector with extended heat transfer area. Findings of this review indicated that PVT air collector with extended heat transfer area produced PVT efficiency higher than conventional PVT air collector. The thermal efficiency of PVT air collector for with and without extended heat transfer area are 21-83% and 12-70%, respectively, which the improvement of thermal efficiency is 15.7-42.8%. 1. INTRODUCTION Energy is a key requirement for undergoing and performing work. Around the 20th century, the demand and energy consumption have increased, and the primary energy source is fossil fuels. At present, the world energy consumption is expected to continuously grow. However, fossil fuel reserves are limited and may not meet the energy demand in the future. In addition, the release of green gas resulting from excessive fossil fuel combustion releases greenhouse gases and causes global climate change. Hence, fossil fuel is an unsustainable energy source. At present, using energy from renewable resources is a key factor in improving and adding benefits to the society because it is sustainable. Solar energy is radiation produced by nuclear fusion and is radiated from the sun in all directions. Solar energy beamed onto the Earth for even an hour is sufficient to produce the global energy need for an entire year. Many technologies are available for harnessing energy from the sun, and such energy can be used in two forms, namely, thermal and electrical energy. Photovoltaic thermal (PVT) technology utilizes radiation from solar energy to produce electrical and thermal energy. This technology consists of a PVT collector, which is a hybrid system that deploys solar PV and solar heater. The solar cell temperature increases when the PV panel is irradiated with solar energy. The higher the difference between the ambient temperature and the temperature of the cell is, the lower the electrical efficiency and electrical output of the PV panel will be. The electrical efficiency can be enhanced through heat extraction by passing a heat-extracting fluid (air or water) under the module. This integrated method, where electrical and thermal energy are generated simultaneously, is the basis of PVT collectors [1-11]. Aste et al. [12] validated a simulation model proposed by Aste et al. [13] based mainly on three balance

Solar energy is free, renewable and environment friendly and has been widely used in electricity generation and thermal energy through photovoltaic thermal (PVT) system. A PVT collector is a combination of a PV panel and a thermal collector in a single unit to simultaneously generate electricity and thermal energy. In this review, mathematical models for dual channel PVT air collectors is presented. This review presents various research and development, as well as heat transfer and thermal modelling of dual channel PVT air collectors. Moreover, various mathematical models that evaluate the performances base on energy and exergy analysis of dual channel PVT air collectors are presented. Energy balance is the basic concept in developing the mathematical models. Generally, steady-state one-dimensional linear first-order differential equations were reported for solution of mathematical model. Energy and exergy efficiencies of dual channel PVT air collectors were 22.5%-67% and 3.9%-58%, respectively. 1. INTRODUCTION Currently, fossil fuels are scarce and expensive, and its future cost and availability are uncertain. Hence, the usage of solar energy in drying of agricultural products will probably increase and further become economically feasible in the near future. Solar energy is a major renewable energy source that has the potential to supply daily energy consumption without polluting the environment. Solar radiation can be converted into electrical and thermal energies by using a photovoltaic (PV) panel and solar collector. The concept of combining a PV with solar thermal collector to obtain electrical and heat energy is not new but has gained limited reasearch attention. Considering the declining supply of energy sources and the increase in their usage, photovoltaic thermal (PVT) technology is eliciting gaining considerable interest. A PVT collector is a combination of a PV panel and a thermal collector in a single unit to simultaneously generate electricity and thermal energy. The main components of a PVT collector are PV panel, absorber, working fluid, and insulator. PVT solar collectors convert solar radiation directly into electrical and thermal energies. A PVT air collector consists of a PV panel and a thermal collector system. The system can produce electrical energy directly converted from sunlight, extract heat from the PV panel and warm the air flow inside the collector [1]-[13]. Tonui and Tripanagnostopoulos [14] developed a simple analytical model using the Fortran90 programming language, based on the energy balance equations between the PVT components, airflow and the ambient and validated against experimental data. This model used the program which uses iterative process to fix the initially guessed unknown parameters accurately and to converge after a few iterations.

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. 1. INTRODUCTION The utilisation of main energy resources by humanity relies on fossil fuels, such as natural gas, oil, nuclear energy and coal. However, the present stocks of fossil fuels are finite and not environmentally friendly. Fossil fuels emit many pollutants and cause serious environmental issues, such as global warming due to greenhouse gas emissions. Thus, renewable energy resources, which fulfil the criteria of green energy, are needed for world development and to meet the increasing demand for energy worldwide. Solar energy, which is the main source of conventional and renewable energy, has great potential and vast application prospects that can be used to meet majority of the total energy demand. The most promising, emerging solar energy technology is photovoltaic (PV) technology, which can transform solar radiation into electric energy through PV panels. From the PV panels, electrical and thermal energy can be produced simultaneously through the conversion of sunlight in the photovoltaic thermal (PVT) solar system [1-8]. Particularly, the development of solar collectors consists of evacuated tube, flat plate and concentrating solar collectors. Depending on specific requirements and technology used, solar collectors and PV systems are highly suitable alternatives for onsite renewable energy generation. They can also be used not only to transfer electricity but also for drying, space cooling and heating for terrestrial applications. Various

The service system of clean water network in Pontianak provided
by the state water company (PDAM Tirta Jaya) in average has high
coverage across the city. Yet, some parts of the community are
still left behind and require attention. This study aims to reveal
which part of the community receive the least service, their current
coping mechanism. It also aims to identify the potential solutions
that PDAM or local community might be able to consider at an
affordable cost. We utilise various datasets related to water, PDAM
customer database, socio-economic background, and spatially related
information. Based on those, we identify that the majority of low-income
households in sub-district Pontianak Utara do not have formal
access to water provision by PDAM. Our Finding on the behavior
of non-piped water households confirms that these are the most
vulnerable community and we propose an alternative solution to
expand the water supply network by building a water bank using
rainwater and runoff especially accessible in the northern area of

Built-up area is easily found in urban areas which is the most land use compared to other land use. The development of the built-up area has also increased with increasing population and increasing economic activity. Most of the population activities in the form of economy, services, trade, offices, education, health, and entertainment facilities that are centralized in urban areas have caused the availability of non built-up area to shrink further. Detection of the built-up area can be assessed from remote sensing data using urban indices, multispectral classification (supervised and unsupervised classification), and spectral bands. This study aims to detect the built-up area based on multisensor and multitemporal imagery. Landsat 5 TM, Landsat 8, ASTER, and Sentinel-2B (LAST) images were used in this study. Digital image processing is performed on each image using the guided classification method support vector machine (SVM) algorithm. Four classes of land cover were taken, namely built-up area, vegetation, bare land, and water bodies. Samples of built-up area classes were taken as many as 31 random sampling points spread over the study area. Validation tests were carried out for each image based on the ground check. Results of the study showed that the development of the built-up area was directed to the north and the difference in the extent of information on the built-up area due to differences in spatial resolution.

The results of this study indicate that in the last six years, from 2010 to 2016 Gorontalo District has DHF outbreak in Limboto sub-district, then in 2013-2016 there are 9 districts that have DHF outbreak of Telaga District, Telaga Jaya, Telaga Biru, West Limboto , Tilango, Tibawa, Bilato and Tabongo marked by an increase in cases every year in the Eastern Region of Gorontalo Regency precisely located in the area of Lake Limboto Area. if diverivikasi use Rainfall data, Dengue incidence in Gorontalo District in 2011 until 2015 is not affected by the amount of rainfall but will be different from the incidence of dengue in 2016 which is actually influenced by the amount of rainfall is high.
Data dan informasi spasial dan temporal sangat berguna dalam upaya mengurangi jumlah kejadain DBD di setiap daerah. Termasuk di Kabupaten Gorontalo yang belum memiliki informasi secara spasial dan temporal mengenai kejadian DBD. Tujuan dari penelitian ini adalah untuk menganalisis data dan informasi kejadian DBD di Kabupaten Gorontalo secara spasio-temporal. Penelitian ini dilakukan di Kabupaten Gorontalo.Sebuah perangkat lunak ArcGIS 10.1 diaplikasikan dalam penelitian ini untuk melihat secara epidemiologi deskriptif yang disajikan dalam bentuk peta, dan tabel yang kemudian digambarkan secara tumpang susun dengan data kejadian DBD melalui sistem informasi geografis (SIG). Hasil penelitian ini menunjukkan bahwa dalam enam tahun terakhir, sejak Tahun 2010 hingga Tahun 2016 Kabupaten Gorontalo mengalami KLB DBD di Kecamatan Limboto, kemudian pada tahun 2013-2016 terdapat 9 Kecamatan yang mengalami KLB DBD yakni Kecamatan Telaga, Telaga Jaya, Telaga Biru, Limboto Barat, Tilango, Tibawa, Bilato dan Tabongo yang ditandai oleh peningkatan kasus pada setiap tahun di Wilayah bagian Timur Kabupaten Gorontalo tepatnya berada di area Kawasan Danau Limboto. jika diverivikasi menggunakan data curah hujan, Kejadian DBD di Kabupaten Gorontalo pada tahun 2011 hingga tahun 2015 tidak dipengaruhi oleh jumlah curah hujan akan tetapi berbeda dengan kejadian DBD pada tahun 2016 yang justru dipengaruhi oleh jumlah curah hujan yang tinggi.

Indonesia's sustainable development system should be disaster-based mitigation. This research aims to analyze spatial geomorphology aspects, that identifies the potential and vulnerability of disaster that can be caused in Leato area (North Leato and southern Leato) at District Dumbo Raya of Gorontalo. Geomorphologically studied aspects using Geographic Information System (GIS) Global Mapper v12 and ArcGIS v10.3. Geomorphological analysis at the location of the research found that the area has coastal morphography up to the steep hills with an average height of 200-500 mdpl and morphometry of 8o to > 55o. Active morphostructure of tectonic activity which lasted relatively continuously since the Eocene - Early Miocene to Quarter, thus making it prone to high earthquake disaster that could become the trigger factor of a landslide. These influences resulted in the formation of geological structures including lithology breakthrough units Diorite Bone (Tmb) and Volcanic rocks Pinogu (TQpv) with a sturdy system that makes the weathering process run intensively on the body of the rock. Rock weathering conditions is a passive morphostructure of a landscape that can affect the cohesiveness of rocks so that some of them become rock fall type material avalanches. In terms of the morphology of the research area, the closure and use of land such as dryland and shrub farming to land and residential land transportation routes make the area not only vulnerable to landslides but also becomes vulnerable to a particularly adverse disaster on sustainable development in Gorontalo.
