Abstract The model of the skipjack tuna resource management that can provide maximum rent can be done with a clear ownership regime (sole owner) or in the condition of MEY balance. However, the management and utilization of skipjack tuna resources must also consider the factors that can result in overfishing of both biological and economics overfishing. This study aims to assess the management and utilization of skipjack tuna fisheries resources in North Gorontalo Regency using a bioeconomic approach. Data processing is done by approaching the bioeconomic model using skipjack tuna fisheries biological and economic parameters. The results showed that the maximum rent obtained in skipjack fisheries in North Gorontalo Regency was at the MEY regime compared to the MSY and OA regime. However, based on the actual data obtained, it is known that the average production of skipjack tuna in North Gorontalo Regency has not reached the optimum catch value in the equilibrium condition of MSY (hMSY ), but in some period the actual catch value has passed the optimal catch value (hMSY ), this means that skipjack tuna has overfished (biological overfishing). While the actual production value of skipjack tuna catches in North Gorontalo Regency has passed the production of optimum MEY (hMEY ). This condition indicates that actually skipjack tuna resources have experienced an economic overfishing.

Penelitian ini bertujuan untuk mengkaji parameter populasi ikan cakalang (Katsuwonus pelamis) yang tertangkap pukat cincin di WPP-572 Samudra Hindia Barat Sumatera dan WPP-573 Selatan Jawa. Hasil penelitian ini diharapkan dapat digunakan sebagai masukan dalam penentuan pengelolaan perikanan sehingga stok ikan cakalang dapat dimanfaatkan secara berkelanjutan. Ikan contoh dikumpulkan melalui program enumerasi tahun 2016 (Januari-Desember). Sampling acak dilaksanakan di empat pelabuhan, yaitu PPS Lampulo (Aceh), PPN Sibolga (Sumatra Utara), PPP Tamperan (Pacitan) dan IPP Pondokdadap (Malang). Jumlah ikan contoh diperoleh sebanyak 14.894 ekor. Serial data fekuensi panjang bulanan diolah menggunakan program FiSAT II untuk menduga parameter pertumbuhan, mortalitas dan tingkat eksploitasi. Hasil penelitian menunjukkan ikan cakalang yang tertangkap di WPP-572 memiliki panjang asimtotik (L)73,5 cmFL, K sebesar 0.22/tahun dan to sebesar -0,59 tahun. Parameter populasi di WPP-573 berturut-turut L”=67,20 cmFL, K=0,27/tahun, dan to=-0,50 tahun. Nilai mortalitas alami (M) ikan cakalang di WPP 572 sebesar 0,49/tahun, mortalitas total (Z) 0,70/tahun, dan kematian akibat penangkapan (F) adalah 0,21/tahun. Ikan cakalang yang tertangkap di WPP 573 menunjukkan nilai (E) sebesar 0,59/tahun, nilai Z 1,02/tahun, dan nilai F sebesar 0,43/tahun. Dugaan tingkat eksploitasi ikan cakalang di WPP 572 dan 573 masing-masing 0,3/tahun dan 0,42/tahun atau belum berada pada tahap optimal.This study aimed to assess the population parameters of skipjack tuna (Katsuwonus pelamis) that caught by purse seine in the Indonesian FMA (Fisheries Management Area) 572 Indian Ocean West Sumatera and FMA 573 South Java. The outcomes of this research can hopefully be used as inputs for fisheries management, in order the stock of skipjack tuna can be utilized sustainably. Fish sample were collected through the program enumeration of Research Institute for Tuna Fisheries (RITF) during the year 2016 (Januari-Desember). Using random sampling method at four fishing ports, namely PPS Lampulo (Aceh), PPN Sibolga (North Sumatra), PPP Tamperan (Pacitan), and IPP Pondokdadap (Malang). The total number of fish samples was 14.894 fish. Monthly length frequency data processed using FiSAT II program to estimate the growth parameters, mortality, and exploitation. The analysis results showed that skipjack tuna caught in FMA 572 has asymtotic length value (L) at 73.5 cmFL, K value 0.22/year, and to at -0.59 year; while in FMA 573 population parameters values respectively 67.20 cmFL, 0.27/year, and -0.50 year. The value of natural mortality (M) skipjack in FMA 572 is 0.49/year, total mortality (Z) 0.70/year, and fishing mortality (F) 0.21/year. Skipjack tuna that caught in FMA 573 showed value of M 0.59/year, Z value 1.02/year, and F value 0.43/year. The estimated values of exploitation levels of skipjack in FMA 572 and 573 were 0.3/year and 0.42/year respectively.

Management And Conservation

<p>In the Pacific, customary marine tenure-ship and management has been practised for centuries. Community based marine resource management (CBMRM) initiatives have seen governments, local communities and non-government organisations adopt various management tools to improve coastal fisheries. Despite these efforts, there are growing concerns over the decline of fisheries resources and the subsequent social-ecological problems that affect coastal communities.  In the last three decades, Fiji, has implemented various forms of CBMRM initiatives with varying social-ecological successes. Marine management and conservation efforts across the 410 qoliqoli areas (fishing grounds) are predominantly driven by Indigenous Taukei communities and non-government conservation organisations (NGOs). Over the past two years local communities, NGOs, and government have led and supported new management efforts to improve fisheries sustainability in the country.  Non-Indigenous resource users are limited by social and political policies to access and participate in coastal resource management. Fijians of Indian descent (Indo-Fijians) represent the second-largest ethnic group in Fiji and are engaged in both subsistence and artisanal fisheries. Their involvement and participation within the broader socio- economic and socio-political aspects of coastal fisheries is considerable, however, remains hidden. Using a qualitative approach, this study explores the issues, challenges, and opportunities that Indo-Fijian communities experience in the coastal fisheries sector in Ba Province, Fiji.  Findings from the research illustrate the informal yet complex nature of socio-economic and socio-cultural community relationships between customary Taukei qoliqoli owners and Indo-Fijian people. The role of Indo-Fijian women within the coastal fisheries sector is notable. The success of contemporary CBRMN in Fiji is dependent upon a re- imagined, re-adapted, diverse approach. Most importantly, this research provides an opportunity to foster discussion within contemporary community based marine management and conservation efforts currently in place by customary Taukei qoliqoli owners, conservation organisations and the government.</p>

Sheep Production

As Kenya grapples with meat deficit and reduced livestock productivity in the ASALs, sheep production in the high rainfall areas offers an opportunity to bridge the gap. Sheep and goats have many advantages over large ruminants for most farmers, including lower capital investment requirement for flock establishment, lower feed consumptions and thus lower food-related costs, high fecundity and thus faster flock building, and are easier to manage. However, sheep production still faces a myriad of challenges that result in low productivity and ultimately low returns to farmers. Projects have been designed and implemented to improve sheep productivity but with little impact. The performance of such projects in terms of timeliness, cost, budget compliance, and quality has been questioned. This research aims to assess how various value chain support activities influence the performance of sheep production projects in Nyandarua County, Kenya. Specifically, the study sought to examine the influence of firm infrastructure assess the influence of human resource management, explore the influence of technology development, and evaluate the influence of procurement on the performance of sheep production projects in Nyandarua County, Kenya. Value chain support activities are the independent variable while the dependent variable is the performance of sheep production projects. The theories that support this study are Capability-Based View, Knowledge-Based View, Resource-based view, and Market-Based View. Descriptive design was used to conduct the study whose population was drawn from sheep production value chain stakeholders in the county, whose population is estimated at 596, 268. A sample size of 271 stakeholders were reached. Qualitative data was analyzed using content analysis while descriptive statistics were used to analyze quantitative data. Descriptive and inferential statistics were used in analyzing the data. Results were presented in form of tables, percentages, bar charts, and graphs. The study found that effective leadership styles has a positive influence on employees’ motivation and morale and contribute positively to organizational and sheep production projects performance. At the same time, human capital planning, acquisition, and development strategies have a more positive influence on organizational and sheep production projects performance than traditional strategies. Further, information technology contributes to the successful introduction of new products or services, improved operational processes and provides guidance to decision making on project implementation and thus affect positively project performance. Moreover, respondents approved that, procurement is a strategic function in that it not only contributes to costs reduction but also to the achievement of budgetary compliance in sheep production projects. It can, therefore, be concluded that firm infrastructure, human resource management, technological development, and procurement are all key success factors in the increased performance of sheep production projects. As part of the recommendation, players in the sheep production value chain should consider adequately investing in firm infrastructure, human resource management, technological development, and procurement. They should also be guided by effective leadership styles that will yield the desired outcome through a positive influence on employees' motivation and morale while exercising human capital planning, acquisition, and development strategies to enhance organizational performance.

The ubiquitous Internet of Things (IoT) devices nowadays are generating various and numerous data from everywhere at any time. Since it is not always necessary to centralize and analyze IoT data cumulatively (e.g., the Monte Carlo analytics and Convergence analytics demonstrated in this article), the traditional implementations of big data analytics (BDA) will suffer from unnecessary and expensive data transmissions as a result of the tight coupling between computing resource management and data processing logics. Inspired by software-defined infrastructure (SDI), we propose the “microservice-oriented platform” to break the environmental monolith and further decouple data processing logics from their underlying resource management in order to facilitate BDA implementations in the IoT environment (which we name “IoBDA”). Given predesigned standard microservices with respect to specific data processing logics, the proposed platform is expected to largely reduce the complexity in and relieve inexperienced practices of IoBDA implementations. The potential contributions to the relevant communities include (1) new theories of a microservice-oriented platform on top of SDI and (2) a functional microservice-oriented platform for IoBDA with a group of predesigned microservices.

Sumberdaya alam memiliki peranan penting bagi negara Indonesia sehingga dalam pengelolaannya diamanatkan pada Pasal 33 UUD 1945. Setiap sumberdaya alam memiliki ketergantungan baik bersifat langsung maupun tidak langsung. Sifat saling ketergantungan sumberdaya merupakan dasar utama yang menjadikan pengelolaan sumberdaya alam yang berkelanjutan menjadi penting untuk dilakukan. Pengelolaan sumberdaya perikanan di Indonesia diantaranya telah diatur dalam Undang-Undang Nomor 31 Tahun 2004 tentang Perikanan sebagaimana telah diubah oleh Undang-Undang Nomor 45 Tahun 2009. Namun sejak tahun 2014 telah terbit Undang-Undang Nomor 23 Tahun 2014 tentang Pemerintah Daerah, dimana didalamnya juga terdapat pengaturan tentang perikanan. Ketika pengelolaan sumberdaya alam diatur dalam berbagai undang-undang dapat menimbulkan saling tidak konsisten, bahkan saling tumpang tindih dan bertentangan dengan segala implikasi didalamnya. Tujuan dari penelitian ini adalah untuk memberikan gambaran terkait pengaturan sumberdaya perikanan di Indonesia yang tercantum dalam Undang-Undang No 31 Tahun 2004 tentang Perikanan sebagaimana telah diubah oleh Undang-Undang Nomor 45 Tahun 2009 dan Undang-Undang Nomor 23 Tahun 2014 tentang Pemerintah Daerah.  Hasil analisis menunjukkan bahwa terdapat perbedaan antara kedua undang-undang tersebut terkait wewenang pengelolaan wilayah penangkapan dan wewenang penerbitan izin pengadaan kapal penangkap dan pengangkut ikan. Adanya perbedaan ini dapat membuat undang-undang maupun peraturan yang telah diterbitkan menjadi tidak efektif dalam implementasinya. Oleh karena itu, turunan dari setiap undang-undang dan peraturan harus segera disusun agar pelaksanaan aturan dapat berjalan efektif tanpa tumpang tindih maupun saling bertentangan.Title: Fisheries Resource Management In Construction Regulations In Indonesia  Natural resources have an important role for Indonesia so that the management mandated by Article 33 of the 1945 Constitution Every natural resource dependent directly or indirectly. The interdependence of natural resources is a main reason for the sustainable management of natural resources is necessary. Fisheries resource management in Indonesia which have been regulated in Law Number 31 of 2004 on Fisheries as amended by Act Nomor 45 in 2009. However, since 2014 has published Law Nomor 23 Year 2014 on Regional Government, where it will also include regulations on fisheries. When the management of natural resources regulated in various laws can be inconsistent, even overlap and conflict with all the implications therein. The purpose of this study is to provide an arrangement related to fisheries resources in Indonesia listed in Act Nomor 31 of 2004 on Fisheries as amended by Act Nomor 45 of 2009 and Act Nomor 23 of 2014 on Regional Government. The analysis showed that there were differences between the two laws related to fishing area management authority and the authority issuing permits procurement of fishing vessels and fish transport. The existence of these differences can make laws and regulations that have been issued to ineffective implementation. Therefore, a derivative of any laws and regulations must be drafted for the implementation of the rules can be run effectively without overlapping or conflicting.

Tuna Fishery

In Indonesia, about 80% of fishing activities are small-scale and play major role both economically and socially. Previous studies mostly concentrated in Java, while in eastern part of Indonesia the information still scarce and limited. The study was conducted from January to December 2013, describes in detail the gears, fleets and catch dynamics of the small-scale tuna fisheries operating based in Labuhan Lombok Coastal Fishing Port (PPP. Labuhan Lombok). Small-scale tuna fishery in Labuhan Lombok are characterized by the small boats less than 10 GT, operating both troll line and hand line simultaneously, targeting large tuna, skipjack tuna and small tuna. Fishing season starts from April to August and influence by southwest monsoon wind and the presence of middleman as the connector between fishers and the market are the main character of the small-scale fisheries business in this area.
