Abstract

AbstractThis study aims to find out about financially analyze the smoked roa fish processing business in Kinabuhutan Village before the Covid-19 and during New Normal, then compare it to determine whether there is an effect of Covid 19 on smoked roa fish processing business in Kinabuhutan Village. The method used was the survey method and the data collection method used the census method because the population was smoked roa fish processing only 3 people. The data collected consisted of primary data and data only. Primary data was collected through surveys and interview. Meanwhile, secondary data from sources related to this study. The data analysis used qualitative descriptive analysis and quantitative descriptive analysis. The quantitative descriptive analysis uses financial analysis such as Operating Profit (OP). Net Profit (NP), Profit Rate (PR). Rentability, Benefit Cost Ratio (BCR), Break Even Point (BEP) and Payback Period (PP). Based on the results of the analysis of data before the existence of Covid 19 regarding Operating Profit (OP) = Rp. 3,053,120,000, Net Profit (NP) = Rp. 3,052,233,400; Profit Rate (PR) = 68%; Benefit Cost Ratio (BCR) = 1.68; Rentability = 14,488%; Sales BEP = Rp. 2,162,439; BEP Unit = 108 clips and a payback period of only 3 days, it can be concluded that the smoked roa fish processing business is very feasible and very promising. Based on the results of the analysis of the data during New Normal, there is absolutely no difference with the time before the Covid 19. smoked roa fish processing business in Kinabuhutan Village. KeyWords: Financial Analysis, smoked roa fish. Kinabuhutan AbstrakPenelitian ini bertujuan untuk menganalisis secara finansial usaha pengolahan ikan roa asap di Desa Kinabuhutan sebelum adanya Covid-19 dan saat New Normal, kemudian membandingkannya untuk mengetahui ada tidaknya pengaruh Covid 19 terhadap usaha pengolahan ikan roa asap di Desa Kinabuhutan. Metode yang digunakan adalah metode Survei dan metode pengambilan data menggunakan metode sensus karena populasinya adalah pengolah ikan roa asap yang hanya 3 orang. Data yang dikumpulkan terdiri dari data primer dan data sekunder, adapun cara pengumpulan data primer melalui survei dan wawancara, sedangkan data sekunder dengan mengutip dari sumber yang ada hubungannya dengan penelitian ini. Analisis data menggunakan analisis deskriptif kualitatif dan deskriptif kuantitatif. Adapun analisis deskriptif kuantitatif menggunakan analisis finansial seperti Operating Profit (OP), Net Profit (NP), Profit Rate (PR), Rentabilitas, Benefit Cost Ratio (BCR), Break Even Point (BEP) dan Payback Period (PP). Berdasarkan hasil analisis tentang data sebelum adanya Covid 19 mengenai Operating Profit (OP) = Rp.3.053.120.000, Net Profit (NP) ; Profit Rate (PR) = 68%; Benefit Cost Ratio (BCR) = 1,68; Rentabilitas = 14.488%;  ; BEP Satuan = 109 jepit dan Payback Period yang hanya 3 hari, dapat disimpulkan bahwa usaha pengolahan ikan roa asap sangat layak untuk dijalankan dan sangat menjanjikan. Berdasarkan hasil analisis tentang data saat New Normal sama sekali tidak ada bedanya dengan pada saaat sebelum adanya covid 19. Setelah dibandingkan hasil analisis data sebelum adanya Covid 19 dengan saat New Normal ternyata sama dan tidak ada perubahan sehingga dapat disimpulkan bahwa Covid 19 tidak mempunyai pengaruh terhadap usaha pengolahan ikan roa asap di Desa Kinabuhutan.Kata Kunci: Analisis Finansial, Ikan roa asap, Kinabuhutan

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

Abstract

This research is to know community structure and gastropod distribution include species density (individual/m2), relative density (%), diversity indices (H’), Evenness indices (E), Richness indices (R), Dominance indices (D) and Dispersion indices (Id).This inestigation was carried out February 2020 in intertidal area, Waleo beach in Minahasa Northern. Quadrat transect placed via area sampling based on substrate difference. Placing quadrat transect was centr on three points that different with distance with point 100 m and distance between quadran 10 m with size quadrat 50 cm2. Based on this research was find 22 species include Cypraea tigris, Terebra areolata, Cymbiola nivosa oblita, Euplica borealis, Turbo argyrostomus, Cypraea moneta, Conus cumingii, Cypraea errones, Tectus fenestrats, Nerita ascensionis, Nerita exuvi, Nerita albicilla, Nerita polita, Nerita Picea, Vasum turbinellus, Lunella cinerea, Nassarius globosus, Nassarius pullus, Vexillum acupictum, Clypeomorus pellucida, Vexillum ebenus, Terebralia sulcata.

Abstract

This research aims to determine the condition of coastal water quality at Sam Ratulangi University's Marine Field Station by looking at the diversity of mollusks and the physical and chemical parameters of the waters as supporting parameters. The method used to determine the research location was the Quadratic Transect method, while to determine the sampling point the random sampling method was used, namely selecting sampling locations randomly based on areas with dominant activities. The mollusks taken are mollusks that are still alive and can be seen attached, both on the surface of the substrate and inside the substrate. Observations of the place and substrate where the individual attached/immersed themselves were carried out by measuring the water quality, where the temperature was 300C, salinity 28%0, and pH 8). The identification results obtained were 29 types. In the final step after the sample has been identified, all data obtained will be analyzed to obtain results from the research carried out. This research is expected to provide information about the condition of water pollution at Sam Ratulangi University's Marine Field Station in determining management policies and preserving the aquatic ecosystem. Keywords: Bioindicators, Molluscs, Diversity, Pollution. Abstrak Penelitian ini bertujuan untuk mengetahui kondisi kualitas perairan pesisir Marine Field Station Universitas Sam Ratulangi dengan melihat keanekaragaman moluska serta parameter fisika kimia perairan sebagai parameter pendukung.  Metode yang digunakan dalam menentukan lokasi penelitian adalah metode Transek Kuadrat, sedangkan untuk menentukan titik pengambilan sampel digunakan metode random sampling, yaitu pemilihan lokasi pengambilan sampel secara acak berdasarkan kawasan dengan kegiatan yang dominan. Moluska yang diambil adalah Moluska dalam keadaan masih hidup yang terlihat menempel, baik di permukaan substrat maupun di dalam subtrat. Pengamatan tentang tempat maupun substrat dimana individu tersebut menempel/membenamkan diri dilakukan pengukuran kualitas air, di mana suhu 300C, salinitas 28%0 dan pH 8). Hasil  indentifikasi diperoleh sebanyak 29 jenis. Langkah terakhir setelah sampel diidentifikasi, semua data yang diperoleh akan dianalisis untuk memperoleh hasil dari penelitian yang dilakukan. Penelitian ini diharapkan sebagai informasi tentang kondisi pencemaran perairan Marine Field Station Universitas Sam Ratulangi dalam penentuan kebijakan pengelolaan serta menjaga kelestarian ekosistem perairan. Kata kunci: Bioindikator, Moluska, Keanekaragaman, Pencemaran.
