Abstract

This research aimed to investigate the distribution, volume, and concentration of iron sand at Wari Ino Beach Tobelo. The resistivity method with Werner-Schlumberger configuration was applied to investigate the iron sand distribution. The measurements were set-up on 3 lines that run parallel along the coast of Wari Ino Village. The length of each trajectory was 150 meters with a spacing of 10 meters for each electrode. Data acquisition was carried out by using geoelectric instruments to obtain current injection (I) and voltage (V). The analysis was carried out by using RES2DINV and ROCKWORK software to obtain 2-D and 3-D cross-section models for interpreting the distribution and volume of the iron sand. The analysis and interpretation were supported by geological data of the location. Furthermore, the Fe content was characterized by using X-Ray Fluorescence Spectroscopy (XRF). There results show that the volume of the iron sand in each trajectory was 109,355 m3; 180,254 m3; and 120,556 m3. The total volume of iron sand along the three trajectories was up to 405,335 m3. The Fe content in the form of a free element is 67.41%, 57.12%, and 73.40%. The Fe content in the form of hematite mineral (Fe2O3) was 57.92%, 45.82%, and 65.47%.

Abstract

The regional election in Lampung province has finished. The events left the amount of ex-campaign props such as banner to become waste. The final landfills and the waste reuse system are still an unsolved issue in Lampung province. A study of materials composition is required to find potential reuse of the waste. One of the traditional products in Lampung province is conventional bricks. Previous studies show that mixing local clay with additional materials such as Rice Husk Ash (RHA) could improve its characteristics, especially water absorption potentiality. This study reported the prototype of bricks with banners waste mix produced employing a conventional method. The method obtains the best admixture composition is 0.002 kilograms banner waste/volume 0.125 liters or 0.02% total weight of clay-dough. The morphology of the prototype shows a similar texture with a non-waste mixture of traditional brick. It is burnt-clay red-bricks, which is used as a control in this study. The prototype bricks show smooth texture and nearly flat on all sides. The addition waste composition ratio of more than 0.002 kilograms indicated cracking texture that affects the market tend to buy bricks, which has good appearance and texture. This study also reported that the mixture's effect is decreasing compressive strength, almost 20% from the control sample.

Abstract

The 21st-Century skills are skills that must be possessed by students to compete in the era of globalization. The provisioning of these skills to students can go through the physics learning process at school. Introduction, Connection, Application, Reflection, and Extension (ICARE) learning model is one of the learning models that can be applied in Physics learning in high school to train students' skills in critical thinking, creative thinking, communication, and collaboration. The purpose of this study was to determine the improvement of communication and collaboration skills of students after applying the ICARE learning model. The research method used was quasi-experimental with a single-group interrupted time series design. The sample were high school students in one of the Karawang districts, consisting of 12 male students and 15 female students. During the learning activities, students will be given a worksheet with several different questions each meeting tailored to the material being studied, and the answer will be used as a source for analyzing their written communication skills. These questions lead students to be able to communicate the results of their experiments following scientific principles. Experimental activities conducted by students will be analyzed to measure their collaborative skills, and students' presentations will be used to measure their oral communication skills. The improvement of those three aspects was analyzed at each meeting. The results showed that the implementation of learning using the ICARE approach was able to improve the ability of students to collaborate with an average score of 7.87 at the first meeting to 15.93 at the second meeting. While the communication, especially report-writing skills of students, increased from the average of1.53 at the first meeting to 3.6 at the second meeting. The aspect of making presentation material increased from 1.67 to 3.17, and the aspect of oral presentation increased from 1.53 to 3.53 at the second meeting. Based on the results obtained, it can be concluded that students' communication and collaboration skills improve after the ICARE learning model implemented

Abstract

Linear air track is often used in physics learning for linear motion experiments because it can reduce friction between objects with trajectories. However,  the use of air tracks for motion experiments in schools often does not care about aspects of air drag, so the purpose of this study is to calculate the air friction contained in the air track and as an offer of enrichment experiments at senior high school. The research method used is an experimental method that uses a set of air track experimental devices consisting of trajectors, carts, blower, and time counters with light sensors. Cart objects with a mass of 120.02 gram is given the initial velocity variation 12.272 cm/s, 16.286 cm/s and 24.599 cm/s. Then the time recorded when the cart crosses the distance of 10 cm to 110 cm at intervals of 10 cm. This experiment is conducted in the Integrated Science Laboratory, Faculty of Mathematics and Natural Sciences, Universitas Negeri Semarang. The second Newton law has been derived to obtain a special exponential function, so the relation between distance and time is obtained. The non-linear relation between distance and time shows the effect of air drag. Then, fitting the graph of the distance and time relation so that the air drag constants obtained are (10.6 ± 0.1) gram/s, (10.6 ± 0.2) gram/s, and (11.1 ± 0.2) gram/s. The results of the air drag constants obtained can be additional data as a factor affecting experiments using linear air track and can be enrichment experiments at senior high school laboratory.

Abstract

The purposes of this research were to investigate the synthesized Nylon-6 nanofibers using electrospinning technique and their characteristics. The method used in this study was an experimental method with a quantitative approach. Nylon-6 nanofibers have been produced using the electrospinning method. This fiber was made with different concentrations, i.e. 20% w/w (FN1), 25% w/w (FN2), and 30% w/w (FN3). The SEM results show that the morphology of all nylon-6 nanofibers) forms perfect fibers without bead fiber. Increasing fiber concentration from 20% w/w to 30% w/w results in bigger morphology and fiber diameter. The dimensions of the FN1, FN2, and FN3 fibers are 1890 nm, 2350 nm, and 2420 nm, respectively. The results of FTIR analysis showed that the increase in the concentration of nylon-6 (b) and the electrospinning process caused a peak shift in the amide II group (CH2 bond), the carbonyl group and the CH2 stretching of the amide III group from small wave numbers to larger ones. The results of XRD characterization showed that the electrospinning process affected the changes in the XRD pattern of nylon-6 nanofiber (FN1, FN2, and FN3) in the state of semi crystal. Nylon-6 nanofibers can be used for applications in medicine, air filters, and electrode for capacitors

Abstract

Gravity measurement has been conducted in South Lampung area to study the characteristics of the distribution of bedrock and igneous rocks, especially those that can be utilized for development in the National Strategic Area of the Sunda Strait. This study uses a 2D qualitative modeling method and utilizing spectrum analysis of complete Bouguer anomaly data. Based on the result of modeling of residual gravity anomaly, it was found that the intrusion pattern on Sulan granitoid pluton and surrounding plutons showed a significant intrusion of the body and scattered in some Tarahan area. 2D qualitative modeling shows Paleozoic metamorphic rocks are responsible as bedding rocks, and the spread was identified scattered throughout the study area, although it cannot be ascertained whether the bedrock in the Bakauheni area is precisely the same rock as the bedrock in Tarahan area. Meanwhile, Quaternary volcanic rocks are still dominated by tuffaceous sandstone and breccia. This method also confirms that andesite lava is commonly found as a product of the eruption of Mount Rajabasa and Pre-Rajabasa in the Bakauheni region. Nevertheless, some potential of basaltic andesite rocks can be obtained in monogenetic volcanic zones exposed around the foot of Mount Rajabasa.

Abstract

Heat rate and heat capacity are widely used to determine the thermal characteristics, especially for wastewater treatment using electro coagulant. This study aimed to determine the value of heat rate and heat capacity of the waste solution in the textile industry, especially in the dyeing waste, by using a microcontroller device. The method for measuring the specific heat capacity and the textile waste solution's heat rate is based on the principle of the first law of Thermodynamics. Temperature measurements were carried out using a digital temperature sensor type DS18B20. In this research, the heat rate and specific heat of the dyeing solution and mineral water used in the textile industry have been studied. This study uses five types of dyeing waste solution as test solutions, namely green waste solution, orange waste solution, blue waste solution, brown waste solution, and mineral water. This experiment's principle is applying Joule's law by using electrical properties with a microcontroller device used to obtain the rise of temperature data each time in real-time every 2 seconds. Based on this research, it can be concluded that the instrument can be used to measure the heat rate and heat capacity of a textile waste solution. Based on this research, we also found that the specific heat of hard water (Hard water is a kind of water with high mineral content, while soft water is water with low mineral content. Apart from calcium and magnesium ions, the cause of hardness can also be other metal ions as well as bicarbonate and sulfate salts) (4.19 ± 0.77) J/ gram ℃ and the specific heat of the four types of waste solution ranged from (3.20 ± 0.72) J/gram ℃ to (6.83 ± 1.71) J/gram ℃ and also it was found that the heat rate of hard water is 0,0471 ℃/s and the heat rate of the four types of waste solution is range from 0,0289 ℃/s to 0,0617 ℃/s.

Abstract

The study's purpose was to describe students' learning difficulties in physics, the causes of students' learning difficulties in physics, and the remediation to solve students' difficulties. This research was exploratory research with qualitative and quantitative approaches. The populations of this study were eleventh-grade students of SMAN 6 Palu. The respondents were chosen based on the lowest posttest results. The research instruments were OSRT treatment, pretest, posttest, and diagnostic test. The data were analyzed by comparing the pretest results, the posttest, and the gain score to determine the improvement after the remediation. Respondent A obtained 0.71 within the high category, respondent B obtained 0.69 within the high category, respondent C obtained 0.85 within the high category, respondent D obtained 0.84 within the high category, and respondent E obtained 0.46 within the moderate category. It can be concluded that internal and external factors caused difficulties. The internal factors were students' weak basic knowledge and weak material prerequisites, while the external factors were the teacher's learning methods that did not attract students' attention. The OSRT can overcome the difficulty in understanding Newton's law's concept to improve their ability to understand physics concepts.
