Abstract

Coral reefs ecosystem of Bangsring provide both commercial and non-commercial goods and services. Local fishermen rely on reef fisheries while tourism activities have been growing in this area. Seeing that the economic benefits derived from coral reefs are vital to the economies of Bangsring communities, economic valuation of these benefits is necessary to guide sustainable and wise use of these resources and to provide useful information for improved decisions. The research was conducted between June 29and August 9 of 2015 aimed to estimate the total economic value (TEV) of coral reefs of Bangsring, Banyuwangi Regency, included passive use values and direct use values. The research was a participatory case study where primary and secondary data were collected using the purposive sampling technique. The study revealed that the estimated TEV of the coral reefs of Bangsring was IDR 41.6 billion per year or IDR 3.2 billion per hectare per year with tourism contributing 60 % or IDR 25 billion per year of the TEV. The healthy coral reefs of Bangsring support local communities and generate billions of rupiahs annually; therefore, it is critical to manage the coral reefs of Bangsring sustainably for current and future generations.
PERKEMBANGAN PENYAKIT KARANG HIAS KOLANG KALING KEMBANG (Catalaphyllia jardinei) OLEH CACING ACOEL FLATWORM (Waminoa sp.) DI PERAIRAN LAUT GILIMANUK, JEMBRANA BALI Dzikrillah Akbar; Muhammad Arif Asadi

Abstract

Terumbu karang adalah salah satu ekosistem yang kompleks, dimana komponen penyusun utama ekoisitem tersebut adalah karang keras. Indonesia merupakan salah satu wilayah Coral Triangle yang aktif melakukan ekspor karang hingga tahun 2017, namun pada pertengahan tahun 2018 ekspor karang hias telah dilarang. Perusahaan hanya mampu melakukan produksi (transplan) dan perawatan karang hias yang di budidaya. Karang kolang-kaling kembang atau elegance coral (Catalaphyllia jardineii) merupakan salah satu karang hias yang dibudidaya dengan kuota besar di area Bali karena memiliki nilai jual tinggi. Koloni cacing acoel flatworm bersifat parasit merambah pada sejumlah karang hias budidaya C. jardineii pada wilayah budidaya di perairan Gilimanuk, Jembrana Bali. Pengamatan perkembangan flatworm dilakukan selama dua kali dalam jeda waktu empat hari pada rak budidaya yang berisi koloni karang hias C. jardineii.  Presentase tutupan flatworm pada pengamatan pertama sebesar 42.76% dan pada pengamatan kedua naik dengan nilai presentase 46.84%. Hasil tersebut diduga akibat waktu kematangan usia, waktu penetasan telur yang cepat serta kesesuaian habitat acoel flatworm pada area pengamatan.

Abstract

Characteristics of plastic debris were assessed among two types of beaches on Bawean Island (windward and leeward) to analyze its sources and long-term effects. Plastic debris was collected inside a 5 x 5 meter transect with five transect plots on each beach per 20 meters. Samplings were carried out three times at intervals of seven days from six different beaches. The average abundances of plastic debris were almost similar between leeward (0.1690.123 pcs m-2) and windward beaches (0.8410.577 pcs m-2). On the other hand, in terms of weight, leeward beaches contained a very low value of debris (0.9270.746 g m-2) compared to windward beaches (4.4793.551 g m-2). Sheets on the windward beaches and wholes on the leeward beaches dominate the shape of plastic debris with the average size was 1520 cm. The color on both type of beaches was dominated by white (38%) and blue (12%). The weathering intensity is 48% on the leeward beach and 52% on the windward beach. The absence of significant differences in size, color, and weathering intensity implies that the debris found came from the same source. The large size and low weathering intensity of the plastic debris means that the debris has not been exposed to hydro-oceanographic factors for an extended period and they came from a local source. The difference in abundance and shape of plastic debris suggests that wind still plays a vital role in shaping the characteristics of plastic debris on Bawean Island.Keywords:Marine DebrisPlastic WeatheringWind DirectionMarine PollutionMacroplastic
