Abstract

A differentiated teaching module based on kurikulum merdeka has been successfully developed on measurement materials in good and practical scientific work. The Alessi and Trollip development model, which consists of three stages, was used in this study. These stages are the planning stage, the design stage, and the development stage. During the planning stage, the researcher performed the following tasks: 1) an analysis of the needs of driving school teachers in three districts, namely Banyuasin, OIC, and East OKU, and 2) a diagnostic analysis of student learning styles at SMA Negeri 1 Semendawai Suku III OKU Timur, and 3) observation and analysis of the independent curriculum structure. Following the planning and design stages, researchers conduct alpha and beta tests during the development stage. The Alpha test is used to determine the level of validity of the developed teaching module. Meanwhile, the Beta test is being conducted to determine the practicability of the developed teaching module. The results of the second Alpha test yielded an excellent percentage of 100%. The acceptable rate of the second Beta test results is 100%. Based on the findings of this study, the independent curriculum-based differentiated teaching module on measurement materials in scientific work developed is valid and practical, making it suitable for use in high school physics learning

Abstract

One of the phenomena of gourami fish is the jumping motion. In analyzing the fish motion, errors are often experienced in observations, tend to be subjective or take a long time. An alternative software to analyze the fish motion is the Tracker software. The study aims to analyze the video of the Gourami fish motion phenomenon using Tracker software in the mechanical energy conservation practicum. This type of research is experimental research. Based on the results, the greater the mass of the fish indicates the greater the kinetic energy and potential energy in the motion of the fish. Kinetic energy depends on the mass and speed of the Gourami fish jumping. While the potential energy depends on the height of the Gourami fish when jumping. It is also affected by the fish's mass and the acceleration of gravity. The video analysis of the motion of the jumping gourami using Tracker can be used in science learning, especially in physics practicum about the law of conservation of mechanical energy

Abstract

Students’ competencies in the 21st century can be achieved if the students have various skills and scientific attitudes. Scientific Attitude will affect students' minds or memories and actions that require in making decisions and problem-solving in the future. So, the aim of this study was to describe the profile of students' scientific attitudes through Practicum Activities Using Student E-Worksheet Based Chemicals at Home. This research used a descriptive quantitative method. The research was conducted in Budi Mulia Dua senior high school, Yogyakarta, Indonesia, at the last of the first semester of the academic year 2021/2022. The observation involved 15 of tenth-grade students as the participant. The data was collected using an observation sheet which was developed based on students' scientific attitude aspects. The instrument has been validated by expert learning lecturers so that it is feasible to use. The data obtained from the students were analyzed descriptively and quantitatively. The results of students’ scientific attitudes were in the good category ie. 75.8%. Therefore, teachers need to innovate the learning process in order to improve students' scientific attitudes

Abstract

Post-harvest handling of horticultural products is very influential on product quality, because storage temperature is one of the important factors to maintain product quality, especially fresh fruits and vegetables. The purpose of this study were to determined the effect of calcium chloride concentration (CaCl2) and starch type as edible coating material against inhibition of chilling injury of tomato. The research method were carried in two stages, namely the preliminary research and main research. The preliminary research was conducted to determine the temperature and time of starch drying.  The main research using Randomized Block Design (RAK) method with 3x4 factorial with 2 replications. The first factor was chloride calcium concentration consisting of 3 levels of a1 (1%), a2 (2%) and a3 (3%). The second factor is type of starch as edible coating material which consists ogf 4 levels of b1 (without edible coating), b2 (sweet potato starch), b3 (cassava starch) and b4 (ganyong starch). The main research responses include chemical responses (vitamin C and total soluble solid), physical responses (weight loss and firmness), and organolptic reponses (color and appearance). Preliminary research results were obtained the temperature of 60 ° C and the best 5 hours for starch drying. The main research results showed that the concentration factor of calcium chloride (A) affected the color and appearance either on day 5 or day 10. The type of starch as an edible coating material (B) had an effect on vitamin (C) content, total soluble solid, color and appearance on day 5 and day 10. Factor interaction of calcium chloride concentration and type of starch as edible coating material influenced to shrinkage oweight, color and appearance on day 5 and day 10. Ganyong starch has better results based on the response of vitamin C, total soluble solid and weight loss.

Abstract

In this work, we carried out a numerical investigation of the PCF-SPR biosensor for the early detection of infected skin cancer cells and healthy cells. The study was conducted using the COMSOL Multiphysics-based FEM method. The dielectric material used in this PCF design is fused silica, while the plasmonic material is gold. The study was conducted to test the effect of the thickness of the plasmonic layer and the size of the air hole diameter on the PCF-SPR. It was found that the larger the diameter of the air hole in the proposed sensor gives a smaller confinement loss value, while the thicker the plasmonic material used also gives a small confinement loss value. The proposed PCF-SPR has a wavelength sensitivity in detecting skin cancer-infected cells of 7000 nm/RIU. These results indicate that the proposed sensor has a good performance in detecting cells infected with skin cancer.

Abstract

We have observed a numerical simulation of the PCF-SPR sensor detecting alcohol concentration at low temperatures. The investigation was carried out using the finite element method on the PCF-SPR geometric structure. We use a simple geometry structure of the sensor by using fused silica and gold as the sensor’s core and plasmonic material. Observations were made in the alcohol concentration range of 15%, 40%, 60%, and 70%. In the literature, we find the refractive index of each alcohol concentration and input its value into the proposed sensor. The proposed sensor shows that the sensor has a sensitivity in detecting alcohol concentrations at low temperatures of 91 nm/%. In the end, we obtained the optimal sensor components and the sensor can detect the alcohol concentration at low temperatures

Abstract

The measurement of magnetic susceptibility, pH, element concentration of Fe and apples diameter has been conducted in orchard soil of Malang, East Java Indonesia. The measurement was performed in two orchards, namely Pujon and Poncokusumo with two different kind of apples in each orchard. This research aimed at exploring in detail linked between magnetic properties, the existence of magnetic mineral as magnetic property carrier in the soil, soil pH, as well as the size of apple diameter to evaluate the quality of apple production in the both areas. The results shows that the soil with lower susceptibility, it was expected that the magnetic mineral of magnetic property carrier to be smaller, low soil pH, meaning that the soil was more acidic which implied on a larger size of apple diameter for Rumbeauty type of apple. Meanwhile, when the soil had a higher susceptibility, and it is expected that the magnetic mineral is also high as well as having high pH, this growing media is appropriate to develop Manalagi type of apple. Based on the observed soil magnetic properties and pH from both observed orchards, it can be suggested that Manalagi apple is appropriate to be planted in Poncokusumo area, while Rumbeauty is appropriate to grow in Pujon area.
