Abstract

The study was conducted in the coastal area of Lembeh Strait, Bitung City, North Sulawesi, Indonesia. Seven districts comprised the test site. The aim of this research was to analyze the activity of fishermen of Sangihe-Filipino descent (Sa-Fi) by multiple regression analysis. Primary data concerning fishing activities of Sa-Fi Fishermen was obtained through interview techniques, questionnaires and field observation. Activity values ​​(Y) show a factor of fishing activities (Xn) which allegedly affect the fishermen activities. These results indicated that the activity of Sa - Fi fishermen affected by the language that they use in carrying out life as a fisherman in Bitung City. Old fishermen settled in Bitung correlated with fishing knowledge. Sa-Fi fishermen fishing knowledge correlated with the number of dependents and income of fishermen families. Sa-Fi fishermen's income is correlated with their spending. Penelitian dilakukan di wilayah pesisir Selat Lembeh Kota Bitung pada 7 kecamatan sebagai lokasi penelitian, untuk menganalisis aktivitas nelayan keturunan Sangihe-Filipina (Sa-Fi) dengan analisis regresi berganda. Data primer mengenai aktivitas nelayan Sa-Fi diperoleh melalui teknik wawancara, penyebaran kuesioner dan observasi lapangan. Nilai aktivitas (Y) menunjukkan faktor kegiatan penangkapan ikan (Xn) yang diduga berpengaruh terhadap aktivitas nelayan. Hasil penelitian ini menunjukkan bahwa aktivitas nelayan Sa-Fi dipengaruhi oleh bahasa yang mereka gunakan dalam menjalankan kehidupannya sebagai nelayan di Kota Bitung. Lama menetap nelayan Sa-Fi di Kota Bitung berkorelasi dengan pengetahuan menangkap ikan. Pengetahuan menangkap ikan nelayan Sa-Fi berkorelasi dengan jumlah tanggungan keluarga dan pendapatan nelayan. Pendapatan nelayan Sa-Fi berkorelasi dengan pengeluaran nelayan.

Abstract

Although heavy metals have relatively low levels in water column and sediments, they will not be degraded and can even be absorbed and accumulated by marine algae. Research on accumulation of heavy metals on algae was done in Kima Bajo Waters, North Minahasa Regency. The research objective was to evaluate the accumulation of four heavy metals, i.e. arsenic (As), cadmium (Cd), plumbum (Pb), and mercury (Hg), on brown macroalgae Padina australis. The alga was introduced and cultivated in the research area using bottom method. The same method was also used in the experiment. One-week acclimatization process was done prior the experiment. Sampling of alga’s thallus was carried out every two weeks to measure the concentration of metals. The experiment was terminated after six weeks. Bottom sediment was also collected at the beginning of the experiment to measure the metal concentration. The results showed that the heavy metals (As, Cd, Pb, and Hg) were accumulated in the algae. The highest concentration of Cd, Pb, and Hg accumulated in the algae was 0.15 mg/kg wet weight, 3.5 mg/kg wet weight, and 0.009 mg/kg wet weight, respectively. All the concentrations were higher than the initial concentration of each metal. Accumulation of As was also occurred with the highest concentration (1,9 mg/kg wet weigh) occurred at fourth weeks; however, it was lower than the initial concentration. The accumulation varied according to type of metals and time; accumulation of Cd, Pb, and Hg were occurred on second weeks of cultivations and As on the fourth weeks. It can be concluded that cultivated alga can accumulate heavy metals.Indonesian title: Akumulasi logam berat (As, Cd, Pb, Hg) pada alga coklat, Padina australis, yang dibudidaya di Perairan Kima Bajo, Kabupaten Minahasa Utara

Abstract

Algae Kappaphycus alvarezii is one of the leading commodities from fisheries and marine sectors in Indonesia. This algae species has many benefits in the fields of marine biology, chemistry, pharmacy, and pharmacology, as well as an excellent nutritional content for health. It is cultivated in the coastal waters of Minahasan Peninsula, especially in Buku Village, Belang District, Southeast Minahasa Regency. This study was carried out to analyze bioactive compound in the algae. Samples of 2-weeks old were taken directly from the cultivation area. Screening test was done qualitatively while an advanced test was done using LC-HRMS method. The results showed 4 bioactive compounds detected in the sample, they are alkaloids, tannins/phenolics, saponins, and flavonoids. From the advanced test, it was found 10 major compounds in the sample, i.e. (2-ethylhexyl) phthalate, phthalic acid, D-(+)-proline, maraniol, stigmatellin Y, Pentyl isopentyl phthalate, methyl thiofentanyl, phenylethanolamine, acetyl hexamethyl tetralin, and fucoxanthin.Indonesian title: Senyawa bioaktif pada alga Kappaphycus alvarezii dari perairan Belang, Kabupaten Minahasa Tenggara
