Abstract

The purpose of this research is to know about: (1) feasibility of flash interactive learning media used by English teachers in speaking skills of grade X at SMA Negeri 16 Medan of Academic Year 2019/2020; and (2) the effectiveness of flash interactive learning media in improving English speaking skills of grade X at SMA Negeri 16 Medan of Academic Year 2019/2020. The research method is the Bord and Gall development model with the learning design of the Dick and Carey Model, consisting of 2 stages: (1) Stage I, namely: conducting preliminary research, making software design, collecting materials, making and producing products, product field testing, and product effectiveness test; and (2) Stage II, product effectiveness test by: normality test, linearity test, hypothesis test, and calculating the value of media effectiveness. Subjects consisted of 64 students of grade X. For the development of products using 2 experts of instructional design, 2 materials experts, 2 software experts, 3 students tested one by one, and 9 small groups classes students. Limited field test shows: (1) the average percentage of the results of the assessment of English-speaking skills by material experts is 79.7%; (2) the average percentage of English-speaking skills assessment results by learning design experts is 86%; and (3) the average percentage of English-speaking skills assessment results by software experts is 80.1%. The results were obtained tcount > ttable (11.315 > 1.69), which concluded that Ho refused and Ha is received, so that it can be stated that there are significant and significant differences between the English-speaking skills of students taught using interactive learning media (82,969) and the average English-speaking skills of students taught using conventional learning media (62,594) can be accepted and tested for truth.

Abstract

Many Batik motifs in North Sumatra are adopted from the decorative motifs of the Batak tribe. The Malay tribe is a symbol of the city of Medan, which has an attractive variety of decorations. This research aims to produce Malay batik motif designs and carry out batik trials on fabric with motifs that have been developed. This research uses the IDI development model. The result of validating the motif design aspect is 0.83, and the motif appearance aspect is 0.88. The functional aspect assessment resulted in a score of 0.87. The assessment result of the color aspect obtained a score of 0.87, and the balance aspect of batik design motifs obtained a score of 0.79. The validation results conclude that the developed batik motif is declared suitable for use in producing textile products in Malay batik. The results of the development of Malay batik can increase its diversity, potentially advancing local culture in the fashion world.

Abstract

Currently, pyrolysis is the primary choice for addressing the significant problems caused by plastic waste. Temperature and catalysts are the main parameters in pyrolysis. However, using catalysts can become a serious problem when scaling up production capacity, as the process can become more complex and expensive due to the high cost of catalysts. Without a catalyst, the required pyrolysis temperature must be sufficiently high to achieve high-quality pyrolytic fuel oil. In this work, plastic grocery bag is pyrolyzed followed by distillation to produce a liquid similar to conventional fuel, called distillate plastic fuel. Non-catalyst and low-temperature pyrolysis was performed at a single temperature of 350 °C, followed by distillation at temperatures of 250 °C and 350 °C to determine the effect of distillation temperature on the chemical properties of the obtained distilled fuel. Elemental and composition analyses were conducted using the GCMS method. Results indicated that the chemical properties and composition of distilled plastic fuel are similar to diesel fuel with a heating value of approximately 43.362 to 44.364 MJ/kg.
