Abstract

This study aims to design and create fluid viscosity test equipment in the form of used oil, sunlight, soklin, liquid rinso, and harpick. The working principle of the viscometer uses a free-falling ball system according to Stokes' law principles. The stages in making a viscometer are designing a tool model, designing hardware and software, designing a mechanical system and testing. Designing hardware includes hall effect magnet sensor, arduino uno, lCD, and power supply. The software uses the Arduino IDE-assisted programming language. The design of the tool includes supports, boxes, magnets, and glass tubes. the test was carried out by measuring the viscosity coefficient of used oil, sunlight, so klin, rinso, and harpick. The viscosity coefficients of used oil, sunlight, floor soklin, liquid Rinso, and harpick from the test results have been able to be measured with a viscometer that has been made.

Abstract

The rapid development of the times will certainly bring up new skills, especially in the era of the Industrial Revolution 4.0 and Society 5.0, which are currently developing. Digital technology is the most important part in building this era. So that this era makes internet-based technology a human companion to carry out their daily activities. With the new environment, of course, the world of education as one part that plays a role in producing human resources must be wise in creating meaningful learning conditions. The condition of a meaningful learning environment is needed in almost all subjects, including physics. One of the learning models that can change or modify the student learning environment is to apply a project-based learning model (PjBL) with six stages, namely: 1) Start with the Essential Question; 2) Design a Plan for the Project; 3) Create a Schedule; 4) Monitor the Student and the Progress of Project; 5) Assess the Outcome; and 6) Evaluate the Experience. The application of the project-based PjBL model received a positive response from students at MA Plus Nurul Islam Sekarbela, this was reinforced by the percentage of student interest in project-based physics learning, which was 55.55% in the "very interesting" category and 26.98% in the "interesting" category, so that by using the model PjBL makes students feel very interested in learning by producing a product, namely student worksheets and learning videos "Physics Experiments" which can be used as guides for other students in need

Abstract

The aircraft used in this study is the upper wing type which has the advantage of flight stability. This upper wing aircraft was designed by the researchers themselves with three different types of wings with a wing span of 1.35m and a fuse lag of 0.925 meters. There are four main forces that work when the plane is in the air, namely lift, thrust, air resistance and gravity. From the results of this study, it can be concluded that the heavier the aircraft unit being flown, the greater the minimum thrust required to fly the aircraft. The measurement results of the 3 aircraft weights, namely 917 grams, require a thrust of 2030 grams of force, whereas for a total aircraft weight of 1,230 grams a thrust of 2510 grams is required, and at an aircraft weight of 1495 grams a minimum thrust of 3040 grams is required. The results also show that the thrust generated is not linear with the throttle position

Abstract

Problems surroundings existence in Indonesia are very diverse, which include associated pollutants withinside the river. Ecology surroundings river in Indonesia has its very own complexities of problems, possibilities and demanding situations which are exceptional from different regions. The major trouble in ecology river surroundings is trouble pollutants garbage plastic mainly microplastic. The cause of this studies is to explain photo and effect pollutants microplastics in rivers. Method used is qualitative or evaluate literature. Microplastic is skilled plastic degradation and length diameter < 5mm. Source microplastic is composed from particularly number one and secondary. Microplastics can input rivers thru effluents from home and business activities. Domestic sewers and business retailers are getting the primary approach of shipping to the river flow. The effect of microplastics at the surroundings may be withinside the shape of pollutants to the aquatic surroundings, together with growing water turbidity and the effect of microplastics on organisms, specifically aquatic organisms, particularly the capability for microplastics to be digested even with the aid of using the smallest organisms withinside the habitat.

Abstract

Refraction of light occurs due to the difference in the speed of light in the two mediums where the speed of light in a dense medium is smaller than the speed of light in a less dense medium. One of the refraction phenomena also occurs in prism glass. Prisms help scatter incoming light from monochromatic light sources. To prove this, refraction experiments can be carried out using a prism. Where the prism used is made manually using used glass made of acrylic. The prism that is made is then filled with water on the inside and a test is carried out to determine the refraction and the value of the angle of deviation. Based on the results obtained, the refraction of the prism glass made in where a beam of light that passes through the prism is deflected from its original direction, while the angle of deviation of the rays is proportional to the angle of incidence

Abstract

This research was conducted to simulate digital image sharpening using the Lusi Richardson deconvolution method. Sharpening was then performed by Lusi richardson deconvolution of the pint spread function of the lens effect. This point spread function is modeled mathematically with a mathematical function approach. The results of the convolution between the Digital Image from a photo of an object are then convolved with the point spread function so as to produce a blurry image. The blurry image is then re-sharpened by deconvolution using the Lucy Richardson convolution method. The results of this deconvolution are then compared with the image of an object photo of reference and then the difference is calculated. The slight difference between the deconvolution result image and the original object photo image indicates that the program is running well. Peak Signal to Noise Ratio (PSNR) Is used to determine image sharpening recovery. The optimum sharpening recovery of deconvolution iteration is obtained in the maximum PSNR value

Abstract

The use of teaching materials has many benefits for students, one of which is to make it easier for students to find information and assist in mastering concepts. This pre-experimental study aims to describe students' mastery of Basic Physics concepts in lectures using e-books. The subjects of this study consisted of all students taking Basic Physics courses at the Biology Education Study Program, University of Mataram, with a total of 27 students. The research was conducted in 7 meetings, starting from October 24 2022 to December 5 2022. The concepts studied consisted of: Static Fluid, Dynamic Fluid, Vibration and Waves, Temperature and Heat. Student concept mastery data was obtained from giving essay tests at the 8th meeting. The level of mastery of the concept is divided into 8 grades namely A, B+, B, C+, C, D+, D, E. Students are declared to have passed if they get grade C, with levels of mastery of concepts ranging from 65 to less than 70. The results showed that the grades the lowest is 66.2 (grade C), while the highest is 91.5 (grade A). The average value of concept mastery is 77.8 (grade B). Thus, it can be concluded that the percentage of students' concept mastery who obtain a pass grade of 100%. The use of e-books can be an alternative teaching material that can be used by lecturers and students in an all-digital era. E-book users can access anytime and anywhere
