Judul: Manajemen Produksi Ikan Teri Nasi di CV. Sumber Rejeki Indramayu
Abstrak: Indramayu is the big anchovy producer in West Java. Anchovy has high selling price fish export, so it caused a lot of processing anchovy companies springing up in Indramayu, one of the company is CV. Sumber Rejeki. So the purposes of this research is to compare practical and theoretical management business of anchovy in CV. Sumber Rejeki, which includes: 1) find out the management of the anchovy raw material; 2) review management production of anchovies start from processing until marketing; and 3) assessing quality management anchovy’s dry products. The methods which used are technical and descriptive analysis, analysis of the classification of production pattern, and quality control analysis using quality control p chart. Collecting data used techniques snowball sampling by observations and an interview with samples. The result showed that the management of raw materials in CV. Sumber Rejeki has not been good for lack of control on raw material. The difference in price anchovy between fishermen and the suppliers is Rp 1.000 up to Rp 2.000. Processing anchovy in general are consisting of two processes that will be divided into the processes that more detail, meanwhile in the marketing export products, CV. Sumber Rejeki cooperate with exporting company. Chirimen product is having quality standard, based on quality analysis, quality of anchovies product by CV. Sumber Rejeki is uncontrolled. They sale 80% (222.525 kg) domestic products and 20% (55.072 kg) export products.

Judul: Analisis Bioekonomi Pengelolaan dan Pemanfaatan Sumberdaya Ikan Teri (Stolephorus sp.) di Perairan Kabupaten Asahan, Provinsi Sumatera Utara
Abstrak: Anchovy is one of important pelagic species produced in Asahan Regency. Anchovy production not only to supply local needs, but also it has been exported to neighboring countries. Based on the analysis of the declining of achovy production showed that there is problem in resource management. The objectives of this research were to study proper anchovy resource management in the Asahan sea. Analytical approaches were used bioeconomic and variance analyses. Bioeconomic analysis using Gordon-Schaefer model approach obtained the actual catchment condition (h) is 725.94 tons/year, effort (E) 947.22 trips/year and the economic rent of Rp 12,648,510,194/year. Catch of MSY level (h) is 1,200.92 tons/year, effort (E) 834.96 trips/year and the economic rent of Rp 22,951,655,440/year. Catch of MEY level (h) is 1,198.41 tons/year, effort (E) 796.75 trips/year and economic rent of Rp 23,004,560,220/year. Current exploitation rate has exceeded sustainable levels of optimal exploitation both in terms of MSY or MEY which lead to overfishing. Based on the estimation of degradation and depreciation rate, the anchovy resource in the Asahan sea has not been degradated and depreciated. This is indicated by the value of degradation and depreciation rate coefficient are 0.27774 and 0.28790. The factors that significantly correlated with fishers perception to anchovy resource are fishing gears, government programs, and the environment are the education levels, fishing experience, and the participation in fisher's organizations. Anchovy resource management can be directed toward MEY conditions to obtain the maximum benefit, but this policy has an impact on the reduction of labor. In order to absorb the larger employment and the sustainability of resource, the resource management policy is directed toward MSY level by reducing fishing gears as much 112,26 units anchovy purse seine from the current level of exploitation. This policy must be supported by clear rule/ regulations and continuous monitored by all parties.

Judul: Cycle Hamilton pada Graf Lengkap, Graf Regular, dan Graf 2-Connected 4-Regular Berorder Kurang dari Sepuluh
Abstrak: Suatu graf disebut graf Hamilton apabila graf tersebut memuat cycle Hamilton, yaitu cycle yang melewati setiap vertex tepat satu kali. Menentukan keberadaan cycle Hamilton pada suatu graf dapat menggunakan syarat cukup yang berupa teorema-teorema yang telah diperkenalkan sejak tahun 1950-an. Beberapa syarat cukup yang dibahas dalam karya ilmiah ini adalah syarat cukup yang berhubungan dengan graf lengkap dan graf regular. Suatu graf lengkap berorder 𝑛������ ≥ 3 dan graf r-regular berorder 𝑛������ ≤ 2𝑟������ + 1 merupakan graf Hamilton, Karena kedua graf tersebut memuat cycle Hamilton. Selanjutnya, syarat cukup tersebut digunakan untuk menentukan keberadaan cycle Hamilton pada graf 2-connected 4- regular berorder kurang dari 10.
