<![CDATA[Fault is a displacement of the land with a certain direction and shift that triggers an earthquake. The existence of faults that are not visible on the surface can be identified by measuring the gravity anomaly above the earth's surface around the fault zone. This study was conducted with the aim of testing the effectiveness of radial derivatives for identification of fault zones, i.e the presence and positions of faults. Radial derivative is a horizontal derivative of the earth's gravity anomaly value with the radial direction away from a certain point that is considered as the radial center. Gravity anomaly data used in this study is synthetic data from computer calculations using the principle of forward modeling from a fault model. This model is in the form of a displacement of the rocks making up the soil at a depth of 100 m with a vertical shift direction of 4 m with an area of the fault zone 600 m x 600 m or 360,000 m2. This synthetic gravity data is then performed a radial derivative treatment. The results of this study show that radial derivatives are able to identify the presence and position of the fault.]]>

<![CDATA[The purpose of this research is to develop a tool for disaster mitigation box as a support for learning disaster in elementary schools. This research uses the R&D approach according to Borg & Gall, which includes the step of development, pilot testing, and the final testing. In The development stage, resulted in seven aspects of the mitigation box namely a disaster poster, disaster impact poster, evacuation map, symbols for evacuation, newspaper clippings, disaster stories and songs about disasters. The seven aspects are declared very feasible to use in disaster learning. The trial phase is a limited trial. Limited trials were carried out 2 times to 32 students in grade III of SD Negeri 6 Mataram. In this limited trial it was stated that this disaster mitigation box was very suitable for learning. Disaster mitigation box testing phase is the stage to determine the effect of the use of disaster mitigation boxes to increase disaster awareness. Increased disaster awareness is determined based on the gain score. The results of the study concluded that the gain score for implementing the disaster mitigation box was 0.50 (medium). The development of the disaster mitigation box teaching aid received a good response from students by 80.80% and according to observers the learning went very well. The results of the research and validation test of learning development experts using disaster mitigation box props are worthy to be used as references in disaster learning.]]>

<![CDATA[Inter-Semester Lectures are identical students whose level of mastery of concept skills is still low. Efforts that can be made to improve students' mastery of concepts are applying learning with the cognitive conflict approach. Students have a very low understanding of concepts in basic physics subjects in temperature and heat. The purpose of this study is to improve the mastery of the concept of students in the material Temperature and Heat. This type of research is a quasi-experimental design with the One Group Pretest-Posttest Design. The sample in this study used students of physics education study programs at one of the universities in NTB. The number of samples in this study was 20 students. The research instrument used was a multiple-choice question. Improved understanding of concepts was analyzed by the N-Gain test. The results showed an increase in mastery of the concept of material temperature and heat after learning with the cognitive conflict approach with an average N-Gain of 0.62 in the medium category]]>

<![CDATA[The seismic refraction method is one of the geophysical methods which is based on measuring the response of seismic waves in the soil that are fractured along the soil and rock layers. One of the applications of the seismic refraction method is to determine the layers and rock types below the surface. This study uses a geophone as a catcher for seismic waves that are emitted below the surface. The waves caught on the geophone are converted into seismic data which can be read in a seismograph. Seismic data read by seismographs are already in digital form and stored in the main unit PASI 16S24-P. The results of the data analysis concluded that below the land surface of the village of Medana, there were 3 rock layers with a thickness of the first layer 3-4 meters, the second layer 2-5 meters and the third layer 10-17 meters. The first and second layers are still in the form of soil (less compact), while the third layer is in the form of rock (compact). The level of hardness (density) will be more compact in linear to the depth, the more the depth will be the more compact the rock. The depth that is in the form of hard rock starts from 16 meters to 23 meters from the ground level of the village of Medana, Central Lombok.DOI: 10.29408/kpj.v4i2.2607]]>

<![CDATA[The Delta Wing aeromodeling aircraft uses a symmetrical airfoil where the top of the wing is the same as the bottom. The main aspects in the design of the Delta Wing aircraft are center of gravity, the engine thrust, the air resistance, the lift and the weight. Delta Wing aircraft are dominated by jet-engined aircraft with the advantages of high speed and small air resistance. From the design and field trials, it was concluded that the minimum thrust of the Delta Win aircraft must be equal to 2 times the total weight of the aircraft so that the aircraft is able to maneuver vertically, perform looping maneuvers, roll maneuvers and hovering. ]]>

<![CDATA[Metoda gravitasi mikro 4D merupakan pengembangan metoda gravitasi dengan dimensi yang ke-empat adalah waktu. Penelitian ini dilakukan untuk menemukan cara yang lebih baik dalam interpretasi anomali gravitasi 4D akibat injeksi fluida disekitar reservoar. Peneliti menggunakan GRABLOX untuk interpretasi anomali 4D sekitar reservoar. Hasil inversi data lapangan menggunakan GRABLOX memberikan nilai volume infiltrasi fluida injeksi yang menunjukkan penyebaran pergerakan fluida injeksi pada reservoar. Parameter fisis lain yang dapat dihasilkan dari GRABLOX dengan modifikasi nilai adalah pengurangan saturasi minyak dan gas akibat injeksi fluida. Hasil inversi menggunakan GRABLOX pada data lapangan menunjukkan adanya perubahan densitas batuan reservoar hingga 0,28 gr/cc yang berhubungan dengan pengurangan saturasi gas dan minyak. Pengurangan saturasi gas akibat fluida injeksi memiliki nilai terkecil 0% dan terbesar hingga 66%. Pengurangan saturasi minyak hanya memberikan sumbangan perubahan densitas 20% dari pengurangan saturasi gas. Hasil uji coba GRABLOX pada data sintetis dan data lapangan menunjukkan bahwa keduanya dapat memberikan gambaran identifikasi pergerakan fluida injeksi di dalam reservoar, serta memberi parameter fisis lain yaitu pengurangan saturasi minyak akibat injeksi fluida.

<![CDATA[This study aims to see the effectiveness of COVID-19 disaster mitigation literacy education on students' knowledge about the spread of the COVID-19 virus, the use of masks, washing hands and maintaining a distance known as health protocols. This study also revealed the response of students to literacy education for the COVID-19 disaster in schools. The research was carried out in class X MIPA 1 SMAN 2 Mataram with Define, Design, Develop, and Desseminate (4D) designs. The results of the study found that literacy education for COVID-19 disaster mitigation was effective in increasing students' knowledge about the spread of the COVID-19 virus and the application of health protocols in schools in the normal era of life. Students also gave a positive response to the COVID-19 disaster mitigation literacy education in schools.]]>
