Judul: Analisis kebutuhan tenaga kerja perikanan tangkap di Kabupaten Halmahera Utara
Abstrak: Pembangunan bangsa Indonesia ke depan sangat tergantung pada kualitas sumberdaya manusia yang sehat fisik dan mental serta mempunyai ketrampilan dan keahlian kerja. Hal ini dibutuhkan agar keluarga yang bersangkutan mempunyai pekerjaan dan penghasilan yang tetap dan layak sehingga mampu memenuhi kebutuhan hidup anggota keluarganya. Kabupaten Halmahera Utara terdapat kurang lebih 17.862 orang penganggur yang sampai saat ini belum dapat diselesaikan permasalahannya. Salah satu upaya untuk menyerap tenaga kerja sehingga angka pengagguran ini dapat dikurangi yaitu dengan menganalisa sumber-sumber kegiatan yang dapat menyerap tenaga kerja. Salah satu sektor penting yang berpeluang menyerap banyak tenaga kerja di Kabupaten Halmahera Utara adalah sektor perikanan tangkap. Melihat pemanfaatan potensi sumber daya ikan Kabupaten Halmahera Utara yang masih sangat rendah, maka perlu ada satu dorongan untuk dapat mengembangkan usaha perikanan, khususnya perikanan tangkap. Pengembangan ini memerlukan tenaga kerja yang siap membaktikan dirinya pada dunia perikanan. Di samping itu, perhatian pemerintah untuk menyediakan sarana dan prasarana yang menunjang perikanan tangkap perlu mendapat perhatian. Pengembangan pasar untuk perbaikan harga komoditas perikanan, pertumbuhan perikanan industri, baik penangkapan maupun pengolahan, bantuan kepada nelayan untuk pengembangan usahanya, semua ini perlu mendapat perhatian serius dari pemerintah agar sektor perikanan tangkap dapat bertumbuh dan berkembang. Dengan demikian maka akan banyak menyerap tenaga kerja pada sektor ini. Penelitian ini bertujuan untuk mengungkapkan informasi tentang kebutuhan tenaga kerja di bidang perikanan tangkap dan spesifikasi tenaga yang diperlukan sesuai dengan alat penangkapan yang dioperasikan, selain itu menganalisis besarnya kebutuhan tenaga kerja di bidang perikanan tangkap dan perkembangannya dari waktu ke waktu, menganalisis keberpihakan kebijakankebijakan pemerintah pada pengembangan bidang perikanan tangkap dan menganalisis keunggulan alat tangkap yang dapat dikembangkan. Hasil penelitian menunjukkan bahwa secara umum alat tangkap yang menunjukkan kecenderungan penurunan produksi dari tahun ke tahun adalah alat tangkap yang daerah penangkapannya di dekat pantai. Sedangkan alat tangkap yang beroperasi di perairan yang lebih terbuka menunjukkan kenaikkan produksi dari tahun ke tahun. Ini menunjukkan bahwa tingkat eksploitasi di daerah pantai sudah cukup tinggi dan harus ada upaya untuk memperluas ekspansi daerah penangkapan ke arah laut terbuka.

Judul: Pengembangan Perikanan Tangkap Berbasis Komoditas Unggulan di Kabupaten Halmahera Utara
Abstrak: North Halmahera Regency with its sea area of 19536.02 km2 (78%) has the potential of fish resources (standing stock) accounting for 664,382.48 tons with sustainable potential fish production (the Maximum Sustainable Yield / MSY) of 347,191 tons per year, i.e., 211,590 tons of pelagic fish and 135,005 tons of demersal per year. The problem in the development of capture fish in North Halmahera is that its excellent commodities are as yet unknown and the policies in the fishery production are not based on excellent commodities. This research is to examine the superior commodities of fishery production, and the policies in capture fishing production in order to increase the income of fishermen. To determine the excellent commodities, the following analyses were made: (1) production continuity, average production, prices, processing and marketing, (2) Method of Location Quotient (LQ) and (3) SWOT Analysis. The results showed that of 38 species of fish that were analyzed, 31 species were of a continuous type and 7 species of non-continuous type. The average fish production is below the average production of all types of fish except for cakalang fish of 11,131.472 tons and flying fish of 4405.296 tons per year. The fish price is generally below average price of all types, except for the following types of fish: beronang, kerapu, lencam, kakap, and kurisi, the prices of which are higher than the average price. The fish products marketed in the local market / overseas are for example kerapu, cakalang and tuna. Fish products are always marketed in fresh form. Only julung-julung fish is marketed after it is processed by fumigation. Three kinds of fish are also exported they are kerapu, cakalang and tuna. The results of LQ calculation show that there are 12 species of fish with a value of LQ>1, namely: kuweh fish, kerapu, kerong-kerong, teri, tembang, julungjulung, tongkol, lemadang, cakalang, mackerel tuna and cucut. Based on the scoring analysis of commodities in terms of production continuity, production, pricing, processing, and marketing associated with the value of LQ, six kinds of fish as excellent commodities in North Halmahera Regency are cakalang, kerapu, anchovies, julung-julung, tuna, and tongkol. Flying fish, although its production is quite high and can be improved, has the value of LQ <1, so it can not be recommended as a superior fish species. Based on the results of the SWOT analysis, there are six government policies of North Halmahera regency related to the development of capture fisheries, increasing fishing fleet is a top priority followed by the development in the processing of captured fish. Both policies are closely related to labor absorption and economic improvement.

Judul: Pelabelan Super Vertex Magic
Abstrak: Super vertex magic labeling is labeling on graph with is a set of edges mapped into and is a set of vertices mapped into . It has a vertex magic labeling in which and represents the size and order of the graph respectively. This manuscript proves that paths, cyclics, and disjoint union of cyclics have a super vertex magic labeling. There are four theorems to be discussed. The first theorem proves that path is super vertex magic if and only if is odd and . The second theorem proves that cyclic is super vertex magic if and only if is odd. The third theorem proves that bijection function from an edge set onto of graph can be extended to a super vertex magic labeling if and only if the set amount of edge label that incidents with a vertex in the graph, consists of sequential integers as many as vertices in the graph. The fourth theorem proves that disjoint union of the cyclics consists of cyclics with each cyclic has vertices is super vertex magic if and only if and are odd.
