Abstrak: Seaweed Kappaphycus alvarezii species Maumere and Tembalang was dominant developed in bay Gerupuk and got a good market response. Seaweed Tembalang and Maumere are the species of Kappaphycus geographically different origins. Both type of seaweed that is the producer of carrageenan. Maumere and seaweed production Tembalang cultivated by longline method is still fluctuating and unstable. Performance of Growth and carragenan seaweed influenced by the availability of nutrients in the water which represented the value of conductivity or electrical conductivity (EC) as well as the lighting and internal factors related to the conductivity of chlorophyll and sea grass. high to low EC of sea water associated with nutrients and affect the process of osmoregulation seaweed. The purpose of the study was to evaluate the performance of seaweed type Tembalang and Maumere in longline system of cultivation by its relationship with EC of sea water. This study was conducted from July to September 2012 in the waters of Gulf Gerupuk, Lombok Tengah regency, Nusa Tenggara Barat Province. Seaweed cultivation was done by longline system using the ris rope 50 m of length each with 2 ropes for Maumere and Tembalang seaweed. Each ris contains 250 seeds clump of seaweed and the distance of each clump was 20 cm. The parameters were analysed consist of daily growth rate (DGR) of seaweed and wet harvesting weights, electrical conductivity (EC) of seaweed and sea water, water quality and quality of carrageenan. The results showed that EC of seawater were significantly different (P ≤ 0.05) with EC of seaweed Maumere (72.41 ± 0.22) and EC of seaweed Tembalang (69.80 ± 0.70). The rate of growth and harvest seaweed Maumere weights were significantly different (P ≤ 0.05) with Tembalang seaweed, which has Maumere seaweed growth rate of 4.36 ± 0.06 % and harvest weight of 743.33 ± 20.82 g. Chlorophyll Tembalang seaweed seaweed significantly different from Maumere the average number of 5.71 ± 0.06 mg/g talus. EC of sea water is positively correlated with performance of seaweed, except viscosity and sulfate are negatively correlated (r = -0997 and r = -0789) in Maumere seaweed and sulfate remain positively correlated (r = 0.193) in the seaweed Tembalang.

Abstrak: One way to determine suitable areas for seaweed cultivation efficiently in terms of cost, time and energy is using remote sensing, however needs to be tested further cultivation. This research aimed to prove the production of seaweed Kappaphycus alvarezii cultivation process, in the suitable areas based on remote sensing at the Bay Gerupuk, West Nusa Tenggara. Seaweed cultivation was done at 3 points (A, B and C) with three repetitions. The results obtained on wet weight measurements of harvest were at point A 556,67 grams, point B 383,33 grams, point C 360 grams. SGR calculation at point A, B and C were 3,89 % ; 3,00 % and 2,86 %. Measurements result of carbohydrate content were at point A 58,07 %; point B 59,49 % and point C 64,44 %. Protein content were at point A 5,68 %; point B 7,23 % and point C 7,55%. Fat content were at point A 0,02 %; point B 0,08 % and point C 0,03 %. Measurements of water content after dried were at point A 27,34 %, point B 26,27 % and point C 26,15 %. Measurement result of a physical-chemical water parameters, overall value of each parameter was still in the proper range for the cultivation activities of seaweed Kappaphycus alvarezii.

Judul: Grup dan Homomorfisma Grup pada Rubik Revenge
Abstrak: Rubik cube is a kind of puzzle game. A player must arrange rubik sides, which have been disordered, back to the position where every side has the same colour. This paper does not focus on the settlement solution, but instead on proving the existence of a group homomorphism between rubik movement group and S96 symmetric permutation group in rubik revenge. Firstly, it has been proved that rubik movement set is a group. Then, it also has been proved that the M set, which contains numeric labels of 1 until 96 in cubinos sides, is S96 symmetric permutation group.
