Implementasi Algoritma Random Walk untuk Procedural Generation dalam Genre Game Dungeon Crawler 2D
Get PDFThe use of algorithms to produce content through procedural generation is an attractive alternative in game development. However, it should be noted that there are various types of algorithms with varying results, as well as their suitability for 2D/3D game types. Random walk is a simple algorithm that is often used in procedural generation. This algorithm works on discrete or continuous space, from an initial position and moves by taking a random direction at each step. The Dungeon Crawler game genre is a type of game that can utilize procedural generation. A game genre that developed from the RPG genre, focusing on the exploration of mazes or dungeons that are often randomized and full of various obstacles. This genre offers several interesting features, such as collecting exploration rewards, solving puzzles, and finding a way out. This research uses GDLC as a system development method based on Windows PC devices. The test results using the Black Box method can be said to be successful because the game succeeded in creating levels automatically by implementing the Random walk algorithm

Get PDFSumbawa Regency is an area with soil water content containing lime. There was even lime blockage in the pipe holes used. So this research aims to create a portable filtration device that is cheap and efficient. The aim of this research is to characterize a portable water filtration device with an innovative absorber from corncob waste. The way this research works is the process of carbonizing corn cob waste and then activating it using 0.5 M NaOH for 24 hours. The absorber is then filled into a portable filter with dimensions of 50 cm in length and 4 inches in diameter. Filtration is carried out by flowing the collected well water into the water reservoir through a filter. Tests are carried out on water that has not been passed through a filter. After that, characterization was also carried out on the water that had passed through the filter. This characterization consists of Total Dispended Solid (TDS), Temperature, pH, Ca levels, and turbidity. The TDS value obtained decreases with the increasing number of absorbers used, namely from 203, 163, to 123 ppm. In addition, the temperature of the test water has almost no change. The resulting results were temperatures of 32, 33, and 32oC. The resulting pH value shows a decrease with an increase in the number of absorbers used, namely from 8.3; 7.7; 7.3. For turbidity, there was a decrease in the turbidity rate with an increase in the number of absorbers used, namely from 0.29 NTU to 0.3 NTU, and 0.28 NTU. In addition, CaCO3 levels decreased with an increase in the number of absorbers used, namely from 330 mg/l, 290 mg/l, and 240 mg/l. This value has met the threshold set by PMK No. 32 of 2017
