Abstract

The purpose of this research is to produce science learning tools using the Discovery Learning model on vibration and wave material to improve student learning outcomes in junior high schools that are valid and suitable for theoretical use. The research method used is the development of a 4D model design which goes through 4 stages including the definition stage, the design stage, the development stage, and the dissemination stage. However, this research is only limited to the development stage. Data collection techniques are through expert validation sheets, practitioner validation sheets, and final semester students. According to the results of this research, it was obtained that implementation of learning by plan and teaching materials had a validity value of 0.85, while for student worksheets 0.87 and learning outcomes tests had a validity level of 0.84 with the criteria based on Aiken (V > 0.80). So that it can be concluded that theoretically it belongs to the very valid criteria and deserves to be tested by other researchers.

Abstract

Tujuan penelitian ini untuk mendeskripsikan kesulitan belajaran fisika dan matematika siswa sekolah menengah atas (SMA) di Papua Barat. Penelitian ini berangkat dari keinginan untuk memetakan dan menemukan letak masalah kognitif bagi siswa SMA di Papua Barat. Metode yang digunakan dalam penelitian ini adalah metode kuantitatif deskripsif, dengan teknik pengumpulan data berupa pemberian tindakan yang diikuti evalusi dan pengukuran kemampuan mengingat berdasarkan indikator kemampuan mengingat konsep, mengingat persamaan, mengingat pola soal, megingat prosedur dan kemampuan mengingat objek visual dalam belajar Fisika dan matematika. Teknik analisis data menggunakan analisis deskriptif, dengan pemetaan persentase kemampuan siswa pada tiga skala ukur yaitu, mampu, kurang mampu dan tidak mampu. Temuan penting dalam penelitian ini adalah kemampuan mengingat siswa dalam pelajaran fisika dan matematika kurang optimal, sehingga hal ini menjadi indikasi kesulitan siswa dalam menguasai aspek kognitif pada tingkatan berikutnya. Namun demikian, kemampuan mengingat siswa pada matapelajaran fisika lebih baik dibandingkan matematika.

Abstract

Penelitian ini adalah penelitian eksperimen yang bertujuan untuk mengetahui karakteristik komposit ZnO-bentonit hasil sintesis. Tahapan penelitian terdiri dari preparasi dan akivasi bentonit menggunakan H2SO4, sintesis komposit ZnO-bentonit dengan metode impregnasi dan karakterisasi komposit ZnO-bentonit menggunakan XRD dan SEM –EDX. Hasil penelitian menunjukkan Bentonit dan komposit ZnO-bentonit dengan karakterisasi instrumen XRD masing-masing menunjukkan terbentuk puncak pada 2θ = 20-62 dan 2θ = 31-57 yang masing-masing mengindikasikan adanya montmorilonit dan ZnO. Karakterisasi morfologi menggunakan instrumen SEM-EDX menunjukkan ZnO berwarna putih tersebar diatas permukaan bentonit yang ditandai dengan hasil EDX dengan persentase O sebesar 90,55% dan sisanya terdapat unsur lain seperti Al (Aluminium) 8,65 %, P (Phsphorus) 0,43 % dan S (Sulphur) 0,37 %.

Abstract

Research on seismicity parameters in the East Nusa Tenggara region can use the a-value and b-value parameters as the main earthquake precursors. The two parameters are seismic activity level and relief level. In general, both parameters use the relationship between between the frequency of earthquake occurrences and magnitude earthquake from the Guternberg-Ritcher law in the form of a graph. This study uses secondary data from the USGS earthquake details which was processed with ZMAP 6.0 software with the maximum likelihood method. Statistics of earthquakes with a magnitude of 4,5 ≤ Mw ≤ 7,9 as many as 1685 events and a depth of 675.5 km in the period 1990-2020. Based on data analysis, the Gutenberg-Ritcher equation is log N (M)=8.72-1.19M where b-value = 1.19, a-value = 8.72, a-value (annual) = 7.23, fractal dimension = 2.38. From this reason, seismic activity in the East Nusa Tenggara region is relatively high, stress levels are low and the source of the earthquake is the main faults cause structural earthquakes and even tsunamis in the seismic tectonics of the arc area basin in front of the Australian plate subducting along the subduction zone in the northern Indonesia. Therefore, the seismic parameters can be used as a long-term earthquake disaster mitigation through knowledge such as socialization before a disaster, during a disaster, and after a disaster by considering the local wisdom of the local community.

Abstract

This study aims to make a temperature measuring device and an automatic hand sanitizer using the MLX90614 sensor, which functions as a body temperature detector, Arduino Uno as a microcontroller which is then displayed on a 16x2 LCD and is equipped with a buzzer as an alarm sign if the temperature exceeds normal limits. The results obtained from measuring body temperature on the back of the hand produce an average value of 36.20 with an average tool error of 0.21% and an instrument accuracy of 99.79%. While the measurement of body temperature on the forehead obtained an average of 36.36 and an average error of 0.47%. Thus, Therefore, the tool is 99.53% accurate. Sensor sensitivity is affected by distance. The further away the sensor is from the object, the sensitivity of the sensor will decrease.

Abstract

Research on the estimation of groundwater potential and its depth has been carried out in Nglanggeran Kulon which is the Nglanggeran Ancient Volcano Tourism Village in Gunung Kidul. The large number of tourists who visit makes the need for groundwater in this location also increases but has not been matched by its availability. This area is also a district that almost every dry season experiences a water crisis. The purpose of this study was to find out the potential presence of groundwater and its depth. This is related to the efforts of local residents who want to build new wells. The method used is the geoelectric resistivity method with the Shlumberger configuration. This method exploits the electrical properties of the rock beneath the surface. The physical parameter measured is the resistivity value to create a subsurface geological model in the form of a 1D model. The length of the stretch carried out is 125 m at two measurement points. The results of this study indicate that 1st point has two layers of rock and no groundwater potential is found. 2nd point has four layers of rock. Groundwater potential is found in 2nd layer because it has a low resistivity value of 9.89 ꭥm at depths ranging from 5-9 meters with a thickness of about 4 meters. So that the location of the 2nd point is more recommended for making new wells.

This type of research uses quantitative and qualitative research methods, by collecting information and data from written test results distributed online to class X students at SMAN 3 Murung. The analysis technique used is descriptive qualitative analysis technique, from data collection conclusions can be obtained (1) There are obstacles experienced by students in understanding the material because the learning system is carried out online. (2) Students have the ability to apply science process skills. (3) Instructional video media need to be developed in physics learning, especially on heat material in order to encourage students to understand the material. (4) A total of 69.20% of students in understanding physics material find it difficult, 92.31% of students have known learning video media, and 92.31% of students stated that science process skills-based learning video media is needed in learning physics, especially heat material, so the media in the form of this learning video needs to be developed.
