Abstract
Analogy transfer is a transfer of learning knowledge from the source problem to the target problem. Analogy transfer can be used to learn new material based on pre-existing knowledge. This study aims to analyze the transfer of analogies in studying new material with and without intermediate problems. The intermediate problem is a problem that has a difficulty level between the source and target problems using the same analogy. This study uses a mixed-method with a quantitative method followed by a qualitative method. The subjects were 45 students of tenth grade class at Gresik Private High School, then 4 students were selected as qualitative subjects. Quantitative data were analyzed based on the percentage of student success and failure in each analogy transfer case, while qualitative data is analyzed based on each phase in the analogy transfer, namely structuring, mapping, applying, and verifying The results showed that the percentage of successful analogy transfer in studies with intermediate problems was greater than in students without intermediate problems. Students with intermediate problems can transfer analogies well in each process. Meanwhile, students without intermediate problems experienced obstacles in the applying process. Students who cannot work on the target problem correctly both experience the analogy transfer failure in the mapping phase.
Keywords: Transfer analogy, new material, source problem, intermediate problem, target problem.

Published: June 2022

This study aims to analyze how the cognitive processes of high school students in terms of their mathematical abilities in solving the Minimum Competency Assessment Numeracy problems related to Geometry and Measurement. Problems were given to three 10th science students with categories of high, medium, and low mathematical ability. Data on the results of the subject's work were analyzed based on the cognitive processes stage, namely the stage of Comprehending linguistic and numerical information in the problem; 2) Translating and transforming that information into mathematical notations, algorithms, and equations; 3) Observing relationships among the elements of the problem; 4) Formulating a plan to solve the problem; 5) Predicting outcome; 6) Regulating the solution path as it is executed; 7) Detecting and correcting errors during problem solution which is then followed by in-depth interviews. The results showed that students with high mathematical abilities went through all stages of the cognitive process quite coherently and completely. While students with moderate abilities went through the stage of understanding information to the calculation stage of planning, but there were some errors and corrections in finding solutions. Meanwhile, students with low abilities had not been able to show the stages of cognitive processes in a coherent manner so that many stages were interrupted and had to return to the stage of understanding the problem. Based on these results, it is hoped that learning for the preparation of the Minimum Competency Assessment for Geometry and Measurement material can be emphasized more and so that the understanding of information on students' problems can continue the completion stage according to the solution plan that they have made.
Keywords: Cognitive Processes, Numeracy, Geometry and Measurement.

Peningkatan kegiatan ekonomi di sebuah daerah bertujuan untuk meningkatkan kesejahteraan masyarakat. Salah satu cara untuk dapat mencapai tujuan tersebut dengan meningkatkan peran UMKM dalam kegiatan ekonomi. Hal ini disebabkan karena UMKM mampu menyerap tenaga kerja yang lebih banyak sehingga berdampak pada pengurangan pengangguran dan pada akhirnya dapat mengurangi jumlah penduduk miskin sehingga dapat meningkatkan kesejahteraan masyarakat. Untuk dapat mencapai tujuan tersebut UMKM harus mampu mempunyai daya saing yang kuat. Terkait dengan hal tersebut maka tujuan dari pengabdian masyarakat ini adalah meningkatkan daya saing pengusaha makanan ringan Di Dusun Dopang Utara, Desa Dopang, Kecamatan Gunung Sari Kabupaten Lombok Barat. Metode pelaksanaan pengabdian masyarakat yang digunakan adalah pertama mengobservasi sasaran target terkait dengan proses produksi, pemasaran dan higine serta sanitasi, kedua menyampaikan materi, kemudian dilanjutkan dengan diskusi serta tanya jawab dan diakhiri dengan pemberian bantuan berupa alat pengupas singkong. Hasil pengabdian menunjukkan pertama, peserta kurang memahami bagaimana cara menciptakan produk agar produk yang dihasilkan mempunyai daya saing serta belum dapat menciptakan pasar bagi produk berdasarkan pada segmentasi pasar yang mempunyai peluang besar dalam meningkatkan produknya. Disamping itu peserta tidak mengetahui apa yang dimaksud dengan higine dan sanitasi serta pengaruhnya terhadap produk yang dihasilkan. Hal ini terlihat dari proses produksi yang dilakukan dilantai, serta penyimpanan bahan baku yang masih bercampur antara bahan baku yang satu dengan lainnya.Pengepakkan produk sangat sederhana dan belum mencantunkan tanggal expired produk. Diharapkan dengan pengabdian ini mitra sasaran dapat mengimplementasikan hasil diskusi yang telah dilakukan sehingga tujuan pengabdian dapat tercapai.

THE PURPOSE. Improving the efficiency of the boiler house. Development of a scheme for the introduction of screw expansion machines (SEM) into the thermal scheme of a boiler house. Calculation of the main technical characteristics of SEM and network heaters. Calculation of the economic effect and assessment of the feasibility of using energy-saving technologies in an industrial enterprise.METHODS. The work uses methods of computational mathematics, the theory of heat and mass transfer, methods of technical and economic calculations in the energy sector, and thermodynamic analysis of power plants.RESULTS. The article presents a variant of improving the efficiency of the boiler shop in Neftekamsk by putting into operation the steam boilers DDVWT, which are mothballed, and introducing screw expansion machines. It is proposed in the non-heating period (April - September) to turn on steam boilers to generate steam. The steam will pass through the SEM, lowering its pressure to that required for network heaters for subsequent heating of water for hot water supply. At the same time, electricity will be generated on the SEM generators, which will be transmitted to the auxiliary tires of the boiler house. According to the results of calculations, two SEM with a capacity of 700 kW each, as well as three network heaters, were selected for the installation. With the considered inclusion of additional steam boilers and SEM in the non-heating period of the year, the generated electricity will fully cover the costs for the auxiliary needs of the boiler house. The payback period of the project will be 5 years.CONCLUSION. The results of technical and economic calculations show the feasibility of introducing SEM into the thermal scheme of the boiler house as an energy-saving measure.

Published: June 2022

THE PURPOSE. In modern control systems of various industrial units, the basis for the automation of technological processes is an electric drive. High requirements for the quality of the control process determine the formulation and solution of scientific and practical tasks for the development and creation of new promising control systems for electric drives (EDCS), allowing to maintain the required quality of functioning under the influence of destabilizing factors. These factors can affect the control system in the form of external disturbances and be summed up with the corresponding signals of the closed EDCS, and also be expressed in the form of parametric disturbances. The need arises to create such a control system that will allow for the identification of the parameters of the EDCS by introducing the appropriate identification algorithms into its structure.METHODS. When solving the problem, a search-free gradient method of adaptive identification was used, implemented by means of the MatLab software environment.RESULTS. The paper considers the problem of parametric identification of an electric drive with a DC motor based on the definition of sensitivity functions. Wherein to construct an algorithm for parametric identification, an inverse model of the studied EDCS is used, the quality indicator is the squared discrepancy, and the identifiable parameter is the overall transmission coefficient of the electric drive.CONCLUSION. Modeling in the MatLab software environment showed a high robustness of the developed identification algorithm to parametric disturbances that do not affect the steadystate value of the identified parameter. The proposed method for compensating the moment of resistance electric drive also made it possible to provide a low sensitivity algorithm to external disturbances. The identification of the overall transmission coefficient of a DC electric drive is carried out with an error not exceeding 0.5% in real time under the conditions of the influence of disturbances of various physical nature.
