By Jason Trikobery, Achmad Rizal, Nia Kurniawati & Zuzy Anna

Abstract:

Garam sebagai salah satu produk sumberdaya perikanan non hayati yang memiliki prospek bisnis yang cukup bagus, karena garam merupakan kebutuhan yang sangat penting bagi manusia seperti bahan pangan, bahan kimia, dan bahan pengawet. Penelitian ini bertujuan untuk menganalisis kinerja finansial dan keragaan produksi tambak garam di Desa Pengarengan. Penelitian ini dilakukan dengan metode studi kasus dengan teknik wawancara dan kuesioner. Kedua skala kelompok usaha tambak garam terdiri dari lahan pribadi dan lahan sewa menunjukkan menguntungkan dan layak untuk dijalankan. Kinerja finansial usaha garam lahan pribadi yakni pendapatan sebesar Rp. 35.210.000, GPM (53%), R/C rasio (1,86), PP (9 bulan), dan NPV hingga 5 tahun mendatang sebesar Rp. 198.139.803. Sedangkan kinerja finansial usaha garam sewa lahan yakni pendapatan sebesar Rp.32.355.000, GPM (53%), R/C rasio (1,74), PP (10 bulan), dan NPV hingga 5 tahun mendatang sebesar Rp. 195.075.632. Secara keseluruhan, benefit yang diterima petambak termasuk baik karena dapat menutupi biaya operasional yang dikeluarkannya dan memperoleh keuntungan.

By Zuzy Anna & Dicky Surya Saputra

Abstract:

The whale sharks aggregation in the waters of Cenderawasih Bay has an impact on improving the marine tourism industry in the region. On the other hands, Whale Shark is one of the species listed in the Red List of Threatened Species by the International Union for Conservation of Nature (IUCN), the vulnerable status, means that a whale shark populations have been reduced by 20% to 50% within 10 years or three generations. The decline numbers of whale sharks caused by human activities that damage the fish and the habitat, such as fishing and tourism activities. This is due to the lack of public awareness about the function and value of these resources and its habitat. The whale shark has inherent value as marine resources, and has an environmental services value, in relation to tourism activities. This paper measures the economic value and environmental services of the whale shark and its habitat. The method of Travel Cost is used to calculate the value of expenditures incurred by both foreign and local tourists. The study also measured the value obtained by tourist operators, the value of fishing activities, and the value of the habitat, through the people’s Willingness to Pay (WTP), using Contingent Valuation Method (CVM). From the result of the overall economic valuation can be determined the estimated value of whale shark tourism, as well as Cenderawasih Bay National Park area, amounted to IDR 35.5 trillion. The policy implication of this research is the need for appreciation of the whale sharks value, as well as its habitat, by managing and developing conservation areas, and community capacity building on the understanding of the importance of whale sharks and its conservation.

Indonesian shrimp resource accounting for sustainable stock management (2017)

Abstract:

Shrimp fisheries is a resource of important economic value, and is one of the high-demand commodities. Although regarded as a resource that has the ability to grow relatively quick and allows for a year-round production, these resources could experience declining production, or even extinction, if not managed properly. Planning the management of shrimp fishery stock requires basic information on the stock dynamics, both in terms of its natural production and utilization, through resource accounting, mandated by the Agenda 21 of United Nation Conference on Environment and Development (UNCED), formulated in the System of Integrated Environmental and Economic Accounting (SEEA). This study measures the accounting of the shrimp resources, both physical and monetary. In addition, the study also aims to measure the shrimp resource that can be utilized (fishable biomass), from the balance of resources. The approach used in this study is a standard bioeconomic model, with Fox model to estimate biological parameters, and methods of System of National Accounts of FAO (2004), named recursive model, adapted to the existing data. The results of the analysis, includes the calculation of standing stocks (physical asset account), fishable biomass, depletion, as well as monetary accounts. Result shows that the overall condition of the stock still in surplus, where the standing stocks from 1988 to 2014, are in the range of 200,000 to 900,000 tons yearly, with the monetary value between IDR 500 billion to 2 trillion. The intrinsic growth of shrimp tend to be positive in average, with values in the range of -258,000 tons to 263,890 tons. The trend estimation for the next five years (2015-2020), showed a decrease in the stock, and the stock closed as many as 350,000 tons in 2020. This paper also suggests the policy recommendations for the development and management of shrimp resources, in Indonesia.
