In 2018, tuna production in D.I. Yogyakarta reached 371.66 tons, of which 75-82% were captured using the handline. The dominance of the tuna caught has led to the development of the handline that highly dependent on the potential of tuna resources. Investment prospects are also important because they become a reference for investors in investing in the tuna handline busineses. This study aims to analyze the potential of tuna fish resources including the spread of its fishing ground and analyze the feasibility of developing tuna handline buseneses in the waters of D.I. Yogyakarta. The data of this study were analyzed using the Schaefer model, mapping using geographic information system (GIS), and investment feasibility analysis. The potential of tuna fish production in the waters of D.I. Yogyakarta reached 628,53 tons/year, while the average production was 427,32 tons/year, so it is still prospective to be developed. Potential fishing ground for tuna handline was spreaded in the waters of Bantul Regency until the western border waters of Gunung Kidul Regency, and in the eastern waters of Gunung Kidul Regency. The tuna handline was also prospective to be developed its investment in D.I. Yogyakarta.

Perairan Kabupaten Tangerang memiliki potensi sumber daya ikan yang cukup besar. Saat ini, pengaruh kegiatan pesisir dan pola penangkapan telah mengakibatkan terjadinya dinamika penangkapan ikan yang mempengaruhi jumlah hasil tangkapan nelayan. Tujuan penelitian adalah menganalisis keragaan perikanan tangkap seperti sebaran jumlah alat tangkap, jumlah kapal penangkap ikan, dan daerah penangkapan ikan di perairan Kabupaten Tangerang. Data keragaan perikanan tangkap dianalisis secara deskriptif, dan pemetaan spasial dianalisis menggunakan sistem informasi geografis kelautan. Hasil penelitian menunjukkan jumlah alat penangkapan ikan di Kabupaten Tangerang sekitar 22.495 unit yang didominasi alat tangkap bubu sekitar 18.750 unit. Sebaran alat penangkapan ikan terbanyak tedapat di Desa Dadap, Ketapang dan Tanjung Kait. Jumlah kapal penangkap ikan di Kabupaten Tangerang sekitar 3.212 kapal yang didominasi kapal berukuran <5 GT yaitu sekitar 2.125 kapal, berukuran 5 – 10 GT sekitar 905 kapal, dan berukuran 10 – 30 GT sekitar 182 kapal. Sebagian besar kapal terdapat di Pusat Pendaratan Ikan (PPI) Kronjo, PPI Cituis, dan Desa Dadap. Daerah penangkapan ikan utama kapal <5 GT mengalami pergeseran ke arah timur laut Kabupaten Tangerang. Daerah penangkapan ikan utama kapal > 5 GT berada di Pulau Lancang, Pulau Laki, Pulau Bokor, dan Pulau Pari. The waters of Tangerang Regency have considerable potential for fish resources. At present, the influence of coastal activities and fishing patterns has resulted in fishing dynamics that affect the amount of fishermen’s catch. The research objective is to analyze the fisheries performance, such as the distribution of the number of fishing gears, the number of fishing vessels, and the fishing grounds in Tangerang Regency waters. Capture fisheries performance data were analyzed descriptively, and spatial mapping was analyzed using a marine geographic information system. The results showed that the number of fishing gear in Tangerang Regency was around 22,495 units, dominated by around 18,750 units of traps. The largest distribution of fishing gear is in the villages of Dadap, Ketapang, and Tanjung Kait. The number of fishing vessels in Tangerang Regency around 3,212 vessels, dominated by <5 GT boats size, namely 2,125 boats, 5-10 GT around 905 boats, and 10-30 GT around 182 boats. Most of the vessels were based in PPI Kronjo, PPI Cituis, and Dadap Village. The main fishing grounds for vessels <5 GT has shifted to the northeast of Tangerang Regency.

This study aimed to develop a Geographic Information System (GIS), for storage of information and geographic location of apiaries in eight counties in western Paraná; study the local flora; the land used; and the honey productivity in the harvest of 2010 in two of these areas: Marechal Cândido Rondon and Santa Helena. In order to do so we used the software SPRING, delimiting a radius of action of bees of three kilometers around the apiaries. We interviewed and registered 126 beekeepers with 383 apiaries. By using the images we selected areas with greater and lower overlap of hives in Marechal Cândido Rondon (144 and 44 hives, respectively) and Santa Helena (165 and 40 hives, respectively), in a three kilometers radius, selecting 15 colonies in each area, for the study of the parameters cited. In the multivariate analysis of the grouping, five groups were formed, by their similarity of management, indicating the higher average production in the hives of the most populated area of Santa Helena and lower average production in the most populated of Marechal Cândido Rondon. The grouping of hives, the differences in the production of honey and floristic survey indicated that these differences could be associated with management, floristic and climatic differences recorded in the period of production, in the areas studied.

<p>Erupsi Gunungapi Merapi tahun 2010 mengakibatkan banyak korban jiwa, kerusakan aset dan kerugian di berbagai bidang. Untuk meminimalkan korban jiwa, kerusakan dan kerugian, diperlukan upaya pengurangan risiko bencana (PRB). Salah satu upaya yang dilakukan adalah program desa bersaudara (<em>sister village</em>) yang digagas oleh Pemerintah Kabupaten Magelang melalui Badan Penanggulangan Bencana Daerah (BPBD). Program desa bersaudara ini bertujuan agar ada kepastian tempat pengungsian, mengurangi kesemrawutan proses pengungsian serta memudahkan pelayanan pengungsi. Program ini dapat memanfaatan Sistem Informasi Geografis/<em>Geographic Information System</em> (GIS) yang berbasis web (<em>WebGIS</em>). <em>WebGIS</em> mampu mendiseminasikan peta yang dihasilkan dalam program desa bersaudara, misalnya peta jalur evakuasi. Makalah ini bertujuan untuk mendiskripsikan pemanfataan <em>WebGIS</em> dalam mendukung program desa bersaudara, dengan mengambil kasus di Desa Ngargomulyo (desa rawan bencana) dan Desa Tamanagung (desa penyangga/ penerima pengungsi). Metodenya adalah memaparkan proses pemetaan jalur evakuasi. Proses penyusunan peta tersebut terbagi empat tahap:   survei lapangan, penyiapan data spasial, coding dan publikasi. Hasilnya adalah tampilan peta jalur evakuasi yang bisa diakses oleh siapapun tanpa menggunakan aplikasi GIS yang memudahkan masyarakat pengungsi, penerima pengungsi, pemerintah maupun parapihak, mengetahui asal pengungsi, jalur evakuasi dan titik pengungsian. Penelitian ini menyimpulkan bahwa pemetaan <em>WebGIS</em> dapat mendukung upaya PRB dengan keunggulan bisa dijangkau pengguna secara sangat luas.<strong></strong></p><p><strong>Kata kunci</strong>: desa bersaudara, <em>sister village</em>, pemetaan jalur evakuasi, <em>gis</em>, <em>webgis</em></p>
