Judul: Karakteristik Bakso Ikan dari Campuran Sumiri dari Ikan Layang (Decapterus spp) dan Ikan Merah (Lutjanus sp) pada Penyimpanan Suhu Dingin
Abstrak: The utilization of Mackerel Scand (Decapterus spp) has not been done yet optimally. This species is potential fish to be processed into sumiri that is a raw material of fish jelly product, such as fishball. Mackerel Scad contains red meat in greater proportion compared using alkaline leaching methode; and mixed with Red Snapper (Lutjanus sp) sumiri to be used a raw material of fishball.

Judul: Pencucian Daging Sirip Ikan Mackerel dan Pengaruhnya Terhadap Karakteristik Produk Olahan yang dihasilkan
Abstrak: Mackerel’s fin flesh contains high fat and has dark color because of lateral line in its nerves coated by fat and flown by blood vessels and myoglobin. In Mackerel’s fillet processing, it produces fins as by-product but the handling and its utilization of the fin was not maximized yet because of undesirable color and aroma. To get a better color, mackerel’s flesh was deboned and washed by sodium bicarbonate solution. Washing is an important step in fish flesh processing which aims to eliminate the soluble material such as dissolved proteins, soluble fat and other impurities materials. This research was objected to utilize fin flesh as mackerel processing by-product, by investigating the influence of flesh washing frequencies by using sodium bicarbonate solution, and to enhance the added-value of mackerel processing by-product for seafood products. Experimental design used was complete randomized experimental design with two factors, i.e. washing frequency of twice and three times, and sodium bicarbonate concentration of 0.2% and 0.5%. The washed flesh was processed as fish-ball product. The results showed that three times washing and 0.5% of sodium bicarbonate concentration could eliminate the highest soluble protein and fat level compared to other treatments, its seafood product had a good acceptance on the odor and color.

Judul: Penggunaan Trie dalam Membangun Frequent ltemset Menggunakan Algoritmc FPGrowth
Abstrak: FP-growth algorithm search for frequent itemset using the FP-tree data structure which is a prefix tree structure based on pattern growth algorithm. Prefix tree in FP-Growth uses the trie structure in the relationship pattern among the items in the database. Trie is a tree structure that uses strings as key, where each descendant represents a character or prefix. To find frequent itemset, FP-growth algorithm build prefix tree recursively. However, recursive function may need longer time than the Iterative (Manolopoulos 2003). Goal of this research is to create alternatives iteratively to the development of frequent iternset using trie on the FP-Growth. Research was conducted on several stages for the development of the frequent itcmset using a trie, stage through pruning and without pruning. In the last stages of testing is done using the input parameters, enter the difference in support, the number of transactions, and the items involved. Testing stage compare the execution time in the computing process through the stage with pruning and without pruning. Thing that affects the execution time is the number of items involved in development process of the frequent itemset. Frequent itemset development with the pruning process will he faster than without pruning, hecause at the time to build a combination of frequent itemset, infrequent items are not in the development process.
