EFEKTIVITAS PENGGUNAAN MODUL FISIKA TERINTEGRASI STEM (SCIENCE, TECHNOLOGY, ENGINEERING, AND MATHEMATICS) MATERI USAHA DAN ENERGI DI SMA

Learning carried out during the pandemic is required to develop technology to support student learning effectively. Solutions for students and teachers to carry out learning effectively by using learning media that students can understand independently at home. Learning media that can support students in independent learning are modules. The module usage by educators related to 21st-century skills to balance the world of education in the modern era can collaborate with models, methods, and approaches in learning, one of which is the STEM (Science, Technology, Engineering, and Mathematics) approach. The purpose of this research is to describe the effectiveness of the STEM integrated physics module. The research method is by giving tests to students in the form of pretest and posttest.

Transition time

2013 is going to be an interesting year for the High Dilution research field. There is a tendency to revise basic concepts and common beliefs, while refining models and theories. The fundamental research team seems to be open to deeper discussions, aiming to reinforce some hypothesis and discharge others. In somehow, we are stuck in a vicious way of think, trying to manage and describe an informational phenomenon into a molecular framework. The challenge offered to those researchers involved with basic science is to figure out how to deal with such phenomenon, since previous theories and models have not shown to be matched! In the other hand, there is a tendency to explore the HD phenomenon in its technological branch. While basic research is important to describe how things work, the applied research has a more intense social and economic appeal. To develop technology based on HD means to give a different kind of visibility to the field, attracting sponsors, companies, entrepreneurs, always committed to the market regulatory laws. I am expecting for this year some important movements, both in the basic and applied research. Of course, it will be only a new beginning, as these changes require a lot of work, discussions and insights. But this transition time is very welcome!

Phenomenological Studies in Reforming Smart Buildings According to the Community Concept 5.0

Today, with the various problems faced by the world community, it requires everyone in various countries to develop technology and science to overcome various problems that are currently faced and predict future problems. Through innovation, the world's technological engineering is felt in the palm of the hand, even if only by means of a cell phone. This condition then inspired the Japanese Cabinet in 2016 to initiate society 5.0 or Society 5.0 through the Japanese Cabinet within the framework of the 5th Science and Technology Basic Plan. The big vision carried by the Japanese Cabinet in the 5th design and technology plan is to create a Super Intelligent Society (MSC). MSC is positioned as the fifth stage of development in the social structure of society, after previously the hunter / gatherer, agrarian, industrial, and information societies. In line with the development and innovation referred to above, the demand for services in the property sector, especially in building buildings, is getting higher. So that the concept of "Smart Building" or better known as Smart Building / Intelligent Building is created. This concept was born as a result of increasing human welfare and changes in modern life patterns that demand a level of service and management of the building environment, which greatly affects the welfare and services in the workplace, which in turn will affect productivity, morality and satisfaction. Therefore, efforts to adjust the current conditions between the speed of information technology development and the growth of a new generation of humans in this era which are almost linear / concurrent, as well as between society and building, are an effort that must be made so that technological and social developments can coincide. . This effort is what is meant by reformulation of Smart Buildings in the Concept of Society 5.0.

PELATIHAN PEMBELAJARAN MATEMATIKA BERBASIS IT DI SD XAVERIUS METRO LAMPUNG

Mathematics is one of the subjects that study abstract objects. The abstraction of material or mathematical concepts requires specific strategies or techniques in teaching it, especially for elementary school students who still have a concrete way of thinking. Learning mathematics in schools should reduce the abstraction of mathematical objects tobe more concrete for students. Learning mathematics in elementary schools tends to use an abstract approach. The dominant learning activities carried out are lectures and assignments. At the same time, the demands of the 2013 curriculum on the implementation of mathematics learning require teachers to creatively find and develop mathematics learning strategies that can direct students in finding, understanding, and applying mathematical concepts in solving problems, especially math problems in everyday life. PGSD Unika Atma Jaya and SD XaveriusMetro Lampung conducted a mathematics learning training that aims to reflect and refresh the knowledge needed to develop the learning required by students. In addition, with the rapid development of technology, teachers also need to learn to use technology, especially tools and applications, to support the implementation of innovative learning. The training results show that teachers are again motivated to develop technology-based mathematics learning by mathematical knowledge and the characteristics of elementary school students. Matematika merupakan salah satu pelajaran yang mempelajari obyek-obyek yang bersifat abstrak. Keabstrakan materi atau konsep matematika membutuhkan strategi atau teknik-teknik tertentu dalam mengajarkannya, terutama bagi siswa sekolah dasar yang masih memiliki cara berpikir yang kongkrit. Pembelajaran matematika di sekolah hendaknya dapat mengurangi keabstrakan obyek matematika menjadi lebih kongkrit bagi siswa. Pada kenyataannya, pembelajaran matematika di sekolah dasar cenderung menggunakan pendekatan abstrak. Aktivitas pada pembelajaran yang dominan dilakukan adalah ceramah dan pemberian tugas. Padahal tuntutan kurikulum 2013 terhadap pelaksanaan pembelajaran matematika mengharuskan guru secara kreatif menemukan dan mengembangkan strategi-strategi pembelajaran matematika yang mampu mengarahkan siswa dalam menemukan, memahami, dan mengaplikasikan konsep-konsep matematika dalam memecahkan masalah terutama masalah-masalah matematika dalam kehidupan sehari-hari. Oleh karena itu bersama Prodi PGSD Unika Atma Jaya, SD Xaverius Metro Lampung melaksanakan pelatihan pembelajaran matematika yang bertujuan untuk merefleksikan dan menyegarkan kembali pengetahuan-pengetahuan yang diperlukan untuk mengembangkan pembelajaran yang dibutuhkan siswa. Selain itu dengan pesatnya perkembangan teknologi, guru perlu juga belajar memanfaatkan teknologi, khususnya pemanfaatan tools (alat) dan aplikasi untuk mendukung pelaksanaan pembelajaran yang inovatif. Hasil pelatihan menunjukkan bahwa guru-guru kembali termotivasi untuk mengembangkan pembelajaran matematika berbasis teknologi yang sesuai dengan karakteristik keilmuan matematika serta karakteristik siswa sekolah dasar.

Effect of legume type and nitrogen source on milk yield among dairy cows fed maize (Zea mays) stover treated with groundnut (Arachis hypogea) and soybean (Glycine max) stover

The main objective of the study was to develop technology for improving utilization of abundant quantities of under- utilized crop residues and leguminous plants during the dry season to mitigate effects of dry season on milk yield. The study was set up to test practical ways of upgrading low quality roughage and their effect on milk yield. A 22 factorial experiment within a Completely Randomised Design (CRD) was used. The study involved improving the quality of maize stover using urea fertilizer (UF), chopped groundnut (cGS) and soybean (cSS) stover, mineralized groundnut (mGS) and mineralized soybean (mSS) solution as sources of nitrogen. Research findings revealed superiority of UET over both groundnut and soybean stover in improving the quality of maize stover. Across legume types, groundnut stover had a higher positive effect on improving the quality of maize stover in terms of milk yield. Within legume stover type mGS showed superior milk yield values than cGS. The reverse was true for soybean stover. The study indicated the effect of improving maize stover with cSS on milk yield was higher than that of mSS in improving the quality of maize stover. It was generally observed that the use of mineralization of legume stover in improving the quality of maize stover is more effective than chopping. Pooled result of effect of mineralised groundnut and soybean stover on milk yield was significantly (p<0.05) higher than that of the chopped forms for the same legume stover. When evaluated across legume type the effect of legume type on milk yield did not differ significantly (p>0.05) for both processing methods.

Development of a highly efficient ion-ozone cavitation technology for accelerated bread production

The bakery market is one of the most capacious in Kazakhstan. Manufacturers of bread products are in dire need of the introduction of intensive technologies for improving product quality and safety. This article presents the results of research to develop technology for accelerated production of bread with ion-ozone cavitation treatment. The influence of various modes of exposure to ion-ozone cavitation has been investigated. After baking, bread samples were examined for organoleptic, physicochemical, rheological and microbiological indicators. The optimal method is treatment with ion-ozone at a concentration of 0.0025 units/mg, at a pressure of 1.0 atm for 1 min. As a result, it was proved that this mode accelerates the process of obtaining dough and shortens the fermentation time, and baking bread increases the qualitative and quantitative indicators according to the control method. The results showed that the ion-ozone technology reduces the length of the process of making dough and bread by three times compared to traditional technologies. The developed products with existing analogues in the Kazakhstan market will differ due to their high taste and consumer properties, product safety, long shelf life and low cost.

Layered shock-resistant element parts shape change process selection and modeling

An impact-resistant layered element consisting of two outer layers from highly rigid material and an inner layer from viscoelastic material has been developed. The item reduces the barring effect on the protected object. The design peculiarity is that the outer part has a bend with a deflection arrow within 10… 15 thicknesses, and has a connection of the outer layers from high-stiff material on opposite edges with staples from plastic material, which during plastic deformation flows into the edge holes coaxially in the outer layers, on the inner side of the impact-resistant element is attached a shock-absorbing layer from elastic foamed polymeric material, the back surface of which corresponds to the surface of the protected object. For the parts manufacture it has been developed bending sheet parts method in which the bending the part shelves with a bending element with their subsequent straightening. The aim is to increase the process productivity and the geometric dimensions’ accuracy of the part. Modeling the process of parts spontaneous forming "Impact-resistant element upper sheet" on the reverse and direct schemes is performed by the finite element method in the AnSYS / AutoDYN system. The study purpose is to develop technology and modeling the process of the impact-resistant element sheet parts deformation.

Cleaning our seas and oceans of plastic litter

Cleaning our seas and oceans of plastic litter Increased global production and poor waste management have led to a build-up of plastic litter in the world’s oceans. This has a devastating effects on ecosystems and marine life. The flow of plastics into the oceans occurs through a variety of pathways, but rivers are one of the largest contributors. The LIFE SouPLess project aims to develop technology to catch plastics from rivers before they spread to the seas and oceans. It is a 4.5 years project (July 2018 – December 2022). Three main links of the chain of riverine plastic recovery will be tackled: from locating plastic hotspots with a dedicated numerical model to effectively collecting the plastics with systems and finding cost-effective solutions for post-processing the collected litter.

Between Food and Respect for Nature: On the Moral Ambiguity of Norwegian Stakeholder Opinions on Fish and Their Welfare in Technological Innovations in Fisheries

Innovation in fisheries is a global development that focuses on a broad range of aims. One example is a project that aims to develop technology for key phases of the demersal fishery operation to improve product quality and safeguard fish welfare. As this step to include welfare is novel, it raises questions associated with stakeholder acceptance in a wider aim for responsible innovation. How do stakeholders (a) value fish and their welfare and (b) consider the relation between welfare and other relevant values? To address these questions, an approach combining desk research with an empirical study was used. The desk study analysed the ethical and biological arguments for whether fish welfare should be accounted for in this context. The empirical study explored how fish and their welfare are perceived by Norwegian professionals in this industry, by conducting semi-structured interviews and subsequently analysing the results based on a labelling method we developed. The desk study showed a consensus that welfare should be considered in its own right, while at face value the interviews presented a rather instrumental view on this theme. However, analysis of the interview results leads to a more nuanced picture, where fish and their welfare are viewed from the perspective of respect for nature. Despite the apparent divergence between stakeholder opinions and the literature on the importance of welfare, we present three steps that enables professionals to be responsive to both the (moral) views of stakeholders and accounting for welfare in the innovation process fisheries.
