Abstract

Tools as media play an important role in learning physics to explain concepts, so that students can more easily build mastery of physics material and develop their skills. This study aims to design and realize a physics learning tool. The method used is research and development (Research and Development). This learning tool is in the form of a plane where the direction of the object's trajectory varies can move up, down, and is accompanied by a slope setting (30˚, 45˚, 60˚ or 90˚). Equipped with a speed output setting program based on 3 points whose speed will be measured and the distance between the points can be changed. Its function is to understand and prove the law of conservation of mechanical energy, understand the relationship between potential energy and kinetic energy experienced by objects and determine the speed of objects and their height position. This learning tool is expected to attract students' interest in learning physics. The design of this KIT Law of Conservation of Mechanical Energy can prove the conservation of mechanical energy. When an object is moving downwards, the object's height decreases but its velocity increases. On the other hand, if the object is moving upwards, the height of the object will increase, but the velocity of the object will decrease. This tool still has a relative error rate of 23.92% in free fall motion, 31.87% in falling motion on an inclined plane, and 32.79% in vertical upward motion.©2021 JNSMR UIN Walisongo.

Abstract

Jepara is a carving city. The result of carving produces sawdust waste which is usually used to be sold and burned. In addition, durian fruit is available that has a distinctive taste and made an icon of one village in Jepara. The fruit is the belle of the whole community to be eaten by meat and made food. But the skin has the traits and characters that are difficult to decompose. Then the two wastes will be combined with tapioca flour into briquettes as an alternative fuel. This research take four stage: combustion, filtering, printing, and drying. Obtained two treatment, the first treatment is using ratio wood sawdust and durian rind; 50 gr: 50 gr; 25 gr: 50 gr; 50 gr: 25 gr. The results shown it does not ignite up and very hard. The second treatment is using same ratio but added 25 gram starch, the results shown it ignite. This is due to the starch content is used, it ignite the longest with a concentration ratio of 50 gr: 50 gr because its combination increases the calories value. In durian rind there are 3786 cal/g and teak wood consists mainly of cellulose (40-50%), hemicellulose (20-30%), lignin (20-30%), and the calories value of sawdust briquettes is 4714-5519 kcal/kg.©2019 JNSMR UIN Walisongo.

Abstract

This study aims to analyze the feasibility and effectiveness of experiment media based on Internet of Things (IoT) to enhance the students' HOTS ability on thermodynamics law material. This Research and Development comprises of the following stages: (1) defining needs, (2) designing products, (3) developing products, and (4) disseminating products. Four expert lecturers and two physics teachers serve as the validator. The limited trial subjects consisted of six students of class XI MIPA SMAN 1 Pekalongan; the field test subjects consisted of 108 students who were randomly selected from all XI MIPA classes at SMAN 2 Batang, and the disseminating subjects were teachers of MGMP physics in Batang. The instruments used were expert validation questionnaires, teacher response questionnaires, student response questionnaires, and written tests. The results of the validation of media experts were 3.81 (very good), and material experts were 3.54 (very good). Meanwhile, the results of teacher responses were 3.92 (very good), and the results of student responses were 3.50 (very good). The effective contribution of the IoT-based experimental media to improve the ability of HOTS can be seen from the results of the Multivariate Test analysis on GLM based on the partial eta squared value of 85.9%. This shows that experiment media based on IoT is feasible and effective to enhance the students’ HOTS ability.

Abstract

This work investigated the effect of post-annealing treatment on the fabrication of zinc oxide (ZnO) thin film by spraying deposition method. Based on SEM analysis, the annealed ZnO thin film at 400˚C presented better uniformity as compared to the non-annealed film. Further measurement by UV-Vis revealed that the lowest optical band gap energy (Eg) (3.22 eV) was achieved by 400˚C sample. These results confirmed that post-annealing treatment enhanced the optical and morphological properties of the fabricated ZnO thin film.
