<p>PRAAT can easily and rapidly improve the students’ ability in pronouncing monophthongs in phonetics class. The effectiveness of this software can help the students acquire quality monophthongs sounds. Furthermore, this software could reduce the problem of students learning sounds of monophthongs accurately such as the accuracy of F1 and F2 that is contained in monophthongs. It provided many programs on how to record, analyze, measure, and save in the wave file. This research aimed to investigate  to what extent this software affects teaching monophthongs sounds in phonetics class for students. This research was conducted with 40 samples of students. They divided the class into 20 students for the control group and another 20 students for the experimental group. This quasi-experimental was to determine the best treatment before and  after giving the treatment by using CALL for the experimental group and NON-CALL for the control group. Before using the software,  the students were given the pre-test . Finally, they  sat for post- test in the last meeting. The result was exposed through analysis of a t-test. It showed a significant difference in learning through PRAAT software (p&lt;.05). In addition to that, teaching vowels sounds proved to be more successful using PRAAT than the traditional method.</p>

Besides being consumed as direct food and animal feed, it is also used as raw material for other industries, such as alternative fuels, polymers, corn oil and others. This study aims to determine maize varieties that have high growth potential and yields in Bireuen District. This research was conducted from September 2020 to January 2021 in the village of Cot Kruet Makmur Subdistri, Bireuen District, Aceh Province. This study used a randomized completely block design (RCBD) consisting of 7 varietas of corn plant, namely the Bonanza variety, Royal 76 variety, Talenta Variety, Ganebo variety, Sweet Boy variety, Paragon variety, Jambore variety. The observed parameters consist of a growth component and a yield component. Growth components include: plant height, number of leaves, stem diameter, and 50% flowering age. While the yield components included: weight of corn cob, length of corn with cob, number of seeds per cob, weight of cob seeds, weight of 1000 grains, and yield per hectare. The result showed that the adaptation test of several varieties of corn plant had a different effect on each observation. Jambore variety is one of the varieties tested for its adaptation in this study, this variety has great potential to be developed in Bireuen district, because the Jambore variety is able to produce the most cobbled cob result among other varieties, weighing is about 22,84 ton ha-1.
