Abstract

Penelitian ini bertujuan untuk menganalis pengaruh pola konsumsi terhadap permintaan kredit konsumtif di kota Banda Aceh dari tahun 2011 sampai dengan tahun 2015. Analisis ini mengguakan independen variable yaitu konsumsi pangan, konsumsi non pangan, jumlah tanggungan, pendapatan dan bunga. Variabel dependennya adalah permintaan kredit konsumtif. Data yang digunakan adalah data primer yang didapat dengan menggunakan teknik Cluster Sampling dan diuji menggunakan model analisis regresi linier berganda. Hasil dari penelitian menjelaskan bahwa pengeluaran pangan dan non pangan berpengaruh negatif dan tidak signifikan terhadap permintaan kredit konsumsi. Secara parsial, jumlah tanggungan, pendapatan dan bunga kredit berpengaruh positif dan signifikan terhadap banyaknya jumlah kredit konsumsi.Kata Kunci : Permintaan Kredit Konsumsi, Konsumsi, Tingkat Bunga Kredit, Pendapatan

Abstract

The tuna fish (Thunnus spp.) is highly migratory and commercial tuna fishery. The fish tuna abudance supported ocea-nography and geography condition in North Mallucas Sea. The fishery targets catch increase on fish tuna provided a view of the need for assessment of phylogenetic tuna. The study was conducted to infer the phylogenetic in North Mollucas Sea. The research method was PCR-Sequensing. Moleculer analysis included extraction, Polymerase Chain Reaction (PCR), electrophoresis and DNA sequencing in control region mtDNA locus. Phylogenetic reconstructed with Neigbor joining with Kimura 2-parameter model using MEGA5. The result showed that four clade (bigeye, yellowfin, alalunga and skipjack). Genetic distance between bigeye with yellowfin was (0.084), bigeye with alalunga (0.163), ye-llowfin with alalunga (0.174), bigeye with skipjack (0.294), skipjack with alalunga (0.312) and yellowfin with skipjack (0.297). The overall result showed significant genetic different. That information explain about one populations species tuna. The tuna phylogeography unlimitedin geographic distributions. AbstrakIkan tuna (Thunnus spp.) adalah ikan pelagis yang memiliki kemampuan ruaya dan nilai komersial. Kondisi oseanogra-fis dan letak geografis mendukung kelimpahan stok sumber daya ikan tuna di Perairan Maluku Utara. Aktifitas penang-kapan yang meningkat memberikan pandangan perlu adanya pengkajian filogenetik ikan tuna. Penelitian ini bertujuan untuk memperoleh informasi filogenetik ikan tuna di perairan Maluku Utara. Metode yang digunakan adalah metode PCR-Sekuensing pada lokus mtDNA control region. Analisis molekuler meliputi ekstraksi, Polymerase Chain Reaction (PCR), elektroforesis dan sekuensing DNA. Rekonstruksi pohon filogenetik dengan metode Neighbor joining dengan model evolusi Kimura 2-parameter dilakukan menggunakan aplikasi MEGA5. Hasil penelitian menemukan empat clade spesies ikan tuna yang berbeda (tuna mata besar, sirip kuning, alalunga, dan cakalang). Jarak genetik tuna mata besar (Thunnus obesus) dengan sirip kuning (Thunnus albacares) adalah 0,084; tuna mata besar dengan tuna alalunga (Thunnus albacore) adalah 0,163; tuna sirip kuning dengan tuna alalunga sebesar 0,174; tuna mata besar dengan caka-lang (Katsuwonus pelamis) adalah 0,294; cakalang dengan tuna alalunga adalah 0,312; dan tuna sirip kuning dengan cakalang adalah 0,297. Semua hasil menunjukkan perbedaan genetik signifikan. Namun dapat dijelaskan bahwa spesies tuna berasal dari satu keturunan. Filogeografi tuna tidak memiliki batas distribusi yang nyata spesies.

Abstract

Tuna is a migratory species with high economic value. Utilization of tuna is increasing and growing every year. Fishing intensity of tuna in the Maluku Sea is high and can disrupt the population. The existence of the population will be threatened if not managed properly. The latest genetic information approach is necessary to prevent the population decline. The purpose of this research was to know the genetic structure of yellowfin tuna in North Maluku waters, Indonesi. Sampling was conducted in May-July 2016 in Morotai Island, Obi and Sanana, while secondary data was gathered in Ternate Island, Bacan and Ambon. A total of 72 samples were collected and analyzed. The result of the study found that the base length (bp) of the control region of mtDNA was found to be 512 bp (base pairs). the genetic distance in the nearest population is at Sanana and Obi (0.025). The results of genetic distance analysis between population found genetic similarity between Morotai-Sanana (0,021), Obi-Sanana (0,025), Obi-Morotai (0,026) and Ambon-Sanana (0,026), while the furthest genetic distance was found in Ternate-Bacan (0,040) and Ternate-Obi (0,042). The pairwise comparison test (Fst) shows a few genetic differentiation between yellowfin tuna populations. The value (Fst) of the yellowfin tuna population shows a strong gene flow between populations. The haplotype distribution shows a relationship between haplotypes in both yellowfin tuna, thus failing to show clade between different geographic locations. Unsustainable use can harm the population through genetic quality. Several approaches should be taken to support the life cycle of yellowfin tuna. The overall result shows that there has not been any change of genetic structure of yellowfin tuna in North Maluku Sea.
