Judul: Pembangkitan dan penyelesaian sliher link dengan answer set programming dan procedural programming
Abstrak: Slither Link is a popular pencil-based puzzle game similar to Sudoku. This problem has been shown to be NP-Complete. The goal of the game is to link grid segments forming a loop such that the number of lines adjacent to a cell is equal to the number written on the cell. In this research, we investigate the use of Answer Set Programming as a formal representation of the game, and to prove an alternative solving method, as opposed to the procedural method. We then perform experiment to test the efficiency of Answer Set Programming compared to the procedural method in solving Slither Link. For the Anser Set Programming method, we use DLV as the solver, whereas for the procedural method we write a program in C++ to solve Slither Link in a procedural manner. The result shows that ASP performed consistently better than the procedural method we use.

Judul: Perbandingan Answer Set Programming dan Iterative Deepening Search dalam Menyelesaikan Game N-puzzle
Abstrak: N-puzzle is one of the known NP-complete problems in the field of puzzles and games. The purpose of N-puzzle is to arrange numbers from 1 to (n2-1) in an n x n grid, with one grid contains a blank square. The research aims to compare the use of Answer Set Programming (ASP), as one of the currently used formalism to express and solve hard computational problems, with the traditional Iterative Deepening Search (IDS) in solving the N-puzzle. An encoding of N-puzzle problem and solver was devised and executed using the DLV system, while IDS is implemented as an ad-hoc program solving the N-puzzle problem. The result of experiment shows that the ASP using DLV is more effective in finding solutions, because it requires no depth parameters to find solutions, while IDS does. On the other hand, the IDS implementation was more efficient in terms of execution time.

Judul: Biology and ecology of the buffalo fly, haematobia exigua de meijere (diptera:muscidae)
Abstrak: The life history of the buffalo fly was observed at room temperature of 27°-29.5°C and at a relative humidity of 48-68 percent. The eggs hatched after 17-22 hours, with an average of 18 hours. First instar larvae measured 1.25 + 0.16 mm long and 0.27 + 0.037 mm wide. reach the second larval stage. It took 6-12 hours to the second instar larvae measured 2.676 +0.187 mm long and 0.353 +0.028 mm wide. The second instar took about 12-24 hours to reach the third larval stage. The third instar measured 6.833 + 0.189 mm long and 0.919 + 0.051 mm wide. It took about 2-3 days for the third instar to become pupae. Duration of the pupal stage was about 5-7 days before the adults emerged. Under laboratory condition, the buffalo fly completed its life cycle in 9.5 to 10.5 days, whereas under field condition it took 9-14 days with an average of 10.5 days. The growth ratio which was based on the measurements of the cephalo-pharyngeal skeleton of each instar was 1.797. The preoviposition period was 8-12 days and mating usually occurred on the 6th or 7th day. The longevity of the male was 29 days, whereas it was 32 days in the female. The range of egg production under laboratory condition was between 20-139 per female fly. The belly and hind legs of the carabao were the most preferred habitat either during cloudy and cool dry or shiny and warm day. When the weather was clear and the carabao was in the shade, the flies tended to be more distributed particularly on the shoulder, dewlap, back and horns. The carabaos had relatively fewer Musca sp. and Stomoxys calcitrans than cattle; never the less carabaos had a higher infestation of buffalo fly than cattle. Oviposition occured either during the day or night but the buffalo flies were more active during the night than in the day time. The effect of various lengths of exposure time of manure in relation to the oviposition was profound. observed, the maximum number of the buffalo flies was occurred when the dung was exposed for 30 minutes. With increasing time of exposure the number and variety of insects also increase. It was evident that Sepsidae and psychodidae were the most dominant insects emerging from the dung. The number of buffalo flies also increased with increasing
