Abstract

Writing works in the form of scientific articles is one of the skills that teachers must have. Not only for promotion needs, but mainly to contribute to academic society on research results in the realm of teaching. Scientific articles written by teachers will enrich an scientific documentations. Moreover when the topics raised in the scientific article are the actual representations of the conditions of teaching and learning in the classroom or school. If many teachers write their scientific works in the form of articles, the above goals will be maximally achieved. However, the counterproductive situation that is still observed today is that very few teachers submit their articles for publication in national journals or proceedings. It is because the lack of knowledge of how to publish their research work and writing skill, then the training for publication in needed for this gap. Therefore, intensive assistance needs to be done so that the gap can be covered. In this present paper, a description of the implementation of scientific article writing training for secondary school science and physics teachers is reported. The training was conducted online with participating teachers spread across various schools in Indonesia. The online training was held for three days and assistance in writing scientific articles for approximately one month, during the COVID-19 pandemic, until the participants succeeded in collecting the final product in the form of scientific articles.

Abstract

As it has been widely known that the spectacular characteristics of nanomaterials are strongly dependent on their particle size, crystal structure, and molecular arrangement. The fine structure formation of nanomaterials is inevitable in an attempt of optimizing their promising applications in various fields. One of the notable nanomaterials up to now is hausmannite or Mn3O4. This paper presents a combination of coprecipitation and sonochemical routes in a concurrent way to produce spinel-structured hausmannite nanomaterials. The pH was varied during the synthesis at values of 9, 10, 11, 11.5, and 12. The crystal structure properties were evaluated by X-ray diffractometry (XRD) with the diffraction angle range of 15° - 80°. The functional groups were investigated by Fourier transform infrared (FTIR) spectrometry having wavenumber from 400 to 4000 cm-1. In this study, pH 10 was found to be the best synthesis parameter in producing Mn3O4. Both XRD and FTIR data analyses have agreed on the formation of spinel hausmannite nanomaterials.

Abstract

Until recently, not only students in middle high schools but also in a university have difficulties in understanding either mathematical representations or physical concept behind scientific phenomena. Those difficulties are then associated with a low level of critical thinking. For instance, in physics, it seems to be not easy for students to attain proper relation among wave speed, wavelength, and frequency. This unproper understanding contributes to students’ low critical thinking skill. One of the most effective ways to overcome the problem is to use student-centred learning with interactive, animated, and game-like learning experiences. Guided inquiry learning and a freely App “Physics Education Technology (PhET)” are believed to meet the criteria. This study focused on the students’ knowledge construction process to be able to think critically the wave-related concepts. This PhET-assisted guided inquiry learning strategy was addressed to 25 students at a junior high school in Indonesia. The objective is to explore the stages of inquiry learning approach using PhET, especially on training them to attain their critical thinking skill. This is a qualitative study that purely involves in-class observation. The lesson plan and student worksheets were prepared as the research instruments. As the results, we found that the use of PhET in the guided inquiry learning model can help students acquire to learn the concept of wave speed, wavelength, and frequency with critical thinking.

Abstract

Produksi komoditas sayuran di Indonesia seperti tomat, cabai, dan wortel, saat ini belum diimbangi dengan upaya kontrol kualitas yang serius. Dampaknya, banyak petani mengalami kerugian karena hasil panennya tidak mampu bersaing dengan sayuran impor. Padahal, Indonesia memiliki kekayaan alam yang potensial khususnya dalam ranah agraria. Sebagai salah satu upaya pencegahan dini terhadap kerugian petani, lahan perkebunan harus selalu dikontrol kualitasnya dengan metode yang lebih efisien dan efektif dengan menggunakan sistem jaringan sensor nirkabel berbasis Arduino Uno. Karakteristik tanah yang penting untuk terus dipantau adalah suhu dan kelembapan tanah. Selain itu, kelembapan udara dan intensitas cahaya di sekitar tanah (sayuran) juga perlu untuk terus dipantau dalam rangka memaksimalkan kualitas sayuran. Dalam penelitian ini, hasil pembacaan sensor pada empat besaran fisis tersebut diproses dengan Arduino Uno dan pembacaannya dikirim ke Thingspeak secara real time. Dengan demikian hasil dari rancang bangun alat ukur ini mampu memberikan solusi untuk meminimalisir kerugian petani sayuran. DOI: http://dx.doi.org/10.17977/um024v4i12019p030

Abstract

Mathematics is the language of physics. The best way to describe a physical phenomenon is by describing its mathematical representations. In addition, viewing the graphical diagram of the corresponding mathematical expression is crucial to deeply understand the physical events. Therefore, setting simple experiments in real time to (1) observe the phenomena, (2) view the related diagrams, and (3) extract the mathematical representations is required. In this study, the real time and simple experimental set-up (consisting of ultrasonic sensor HC-SR04 connected to an Arduino Uno board) was designed to perceive the motion of a spring-mass system. The spring force, which is equal to the object’s weight, and displacement or spring elongation data were recorded for the object (with varying mass) attached to the spring. A small external downward force was given to stimulate the simple harmonic motion of the vertical spring-mass system. The displacement as the function of time of the spring-mass motion was recorded. With those measurements, the sinusoidal patterns, representing the simple harmonic motion characteristics, were also observed. The spring constants were 6.35(2) N/m and 6.26(1) N/m for the displacements measured by sensor and ruler, respectively. The periods form the angular frequency of the displacement function and from the spring constant (acquired from sensor data fitting) showed consistent results with very high accuracy. This simple experimental set-up is believed to fulfill the technological-based learning demand.

Abstract

Although thousands of tribes, with their unique characters, are scattered throughout the earth of Indonesia, the country remains intact into a single unitary state. This country's wealth is important to be introduced not only to Indonesian people, but also to international citizens. In this community service, we had the opportunity to bring University of Malaya international students to learn about one of the cultures and lives of the people of Gubugklakah and Tengger villages. This activity was done for two days and before the Covid-19 pandemic. They were even invited to live with residents to truly feel how to live in a traditional environment. The international students learned about language, ethnic, religion, way of life and the natural conservation in Indonesia. This is an important and unforgettable experience for anyone who has never touched the beauty of life in a village where the houses are not restricted by locked fences.
