Abstract

Philosophy will be closely associated with the nature, principles, and laws governing all existing reality. This study examines the ontology, epistemology, and axiology aspects of the junior high school concept of pressure. The method used in this study is conducting studies from various books, journals, articles, magazines, and other scientific references related to the research topic. The data collection process in this study was divided into three stages: (1) editing, (2) organizing, and (3) finding. According to the findings of various studies, the ontological aspect of pressure explains what exactly pressure is. What does it accomplish? What kind? While the epistemological aspect of the concept of pressure is related to an explanation of the discussion related to the epistemological aspect of the idea of pressure will be studied regarding (1) the discovery of the idea of pressure, (2) the idea of pressure; (3) the laws that apply to the matter of stress. Meanwhile, the axiological aspect explains how pressure is useful and the laws that govern it in various aspects of human life. Thus, teachers should pay attention to the ontology, epistemology, and axiology aspects of the concept of pressure when teaching it in junior high school.

Abstract

Frequency is fundamental in data communication for transmitter and receiver stations. The most common problem found in the data communication is the signal quality measurement. A LoRa module, as one of the wireless devices with UHF (Ultra High Radio) frequencies, has extended range frequencies and signal strength parameters (RSSI, Received Signal Strength Indicator). RSSI parameter on signal bandwidth and the distance between stations. However, there is no supporting research in terms of the RSSI quality and short-distance variations. In line with this, this study aims to design a frequency control system of a LoRa module and to investigate the effect of short-distance and frequency differences on RSSI. The system consists of a transmitter, a LoRa SX1278 module, and push buttons as frequency control buttons. The system's performance was tested by receiving data over various distances from 0 to 1.25 m. The results show that the system works efficiently in controlling the frequency (ranging from 433 – 525 MHz) with good flexibility and accuracy. The system maintained an RSSI level > -120 dBm using a constant power supply and varied distances. The highest RSSI level is found at the shortest distance (0.2 m) with a higher frequency (525 MHz). There is a significant correlation between distance, frequency variations, and RSSI levels (R2 > 0.75). It can be concluded that the LoRa SX1278 module can be used as a short-distance-based data communication with moderate quality (average RSSI levels are about 80 - 120 dBm). Higher frequencies provide better RSSI levels due to increased transmission energy.

Abstract

The universe is a space containing large amounts of both organic and inorganic carbon that has the potential to encourage heterotrophs on habitable planets. Meteorites are materials that can transport carbon from outer space to the planet's surface. Meteorites bombarded the Earth's surface during the early days of evolution and proliferation of life, potentially providing a source of abiotic organic carbon to support early life. This study aims to analyze research methods used in detecting the use of space organic carbon, analyze research results related to the role of space organic carbon, and provide further understanding to the researchers associated with organic carbon from space and its potential in human life on Earth. This study uses a systematic review method using 15 sources of information from national and international news and journal articles related to space organic carbon and its potential. This study showed that extraterrestrial organic carbon produces a source of carbon that is beneficial for microorganisms to integrate into their proteins. Combining inverse stable isotope labeling and infrared spectroscopy shows that organic carbon from Aguas Zarcas carbon chondrite can be harnessed for cell growth. Previous discoveries have also shown that aerobic microbial communities have potential in human space settlement plans to access and research carbonaceous asteroid material.

Abstract

Functional group analysis of silica gel synthesized from river sand magnetic minerals using the sol-gel method was conducted. River sand magnetic mineral samples were taken from Sompang River, Lombok. The synthesis method used is a sol-gel method with variation of HCl acid 10 M and NH4OH base 10 M. Morphological characterization using a Scanning Electron Microscope (SEM) and mineral content analysis using Energy Dispersive X-ray (EDX). The morphology of the resulting silica gel is granular, showing crystalline properties with a silica concentration of 77.99 ± 0.17 atomic percent. Silica functional groups before absorption showed three stretching vibrations, namely OH group stretching vibrations in Si-OH and H2O at an absorption wavelength of 3669.77 cm-1, Si-O stretching vibrations from siloxane (Si-O-Si) at an absorption wavelength of 2858.51 cm-1 and Si-O asymmetric stretching vibrations from silanol (Si-OH) at an absorption wavelength of 962.88 cm-1. While the results of the analysis of silica gel after absorption show that almost all samples have vibrational absorption in the range of 400-500 cm-1. Other vibrational absorptions in silica samples that have been used as water filters indicate that the bonding between nano-silica as an absorber and heavy metals is due to the magnetic properties of nano-silica.

Abstract

The main problem in physics education among students is the lack of interest in learning due to monotonous teaching methods such as lectures. Lectures are often considered uninteresting and ineffective. This research aims to assess the effectiveness of a Thunkable-based application named Archio in increasing learning interest. The study uses the 4-D development model (Define, Design, Develop, Disseminate) and was conducted at the end of 2023. The Define stage involved a survey to identify students' learning difficulties, which showed Archimedes' Law as the most difficult material. The Archio application was then designed (Design) and developed (Develop) with features such as learning materials, interactive simulations, quizzes, and reflections. At the Disseminate stage, the application was introduced through posters. The application received scores of 4.30 and 4.20 from expert and student validation results. The validation results indicated that the application is suitable for use with a very good category. The recommendation from this research is further development of the Archio application based on validator feedback to ensure its wider and smoother usage

Abstract

Seawater intrusion increases groundwater salinity and affects the quality of residents' healthy water around coastal areas. Therefore, simple mapping of seawater intrusion distribution based on the salinity values of healthy water around coastal areas is necessary. This mapping can be done by measuring the salinity of the water using a portable and real-time instrument. The existing measurement system is not resistant to corrosion, does not have a data logger system, and does not have a display system capable of showing real-time salinity value graphs. In this study, a portable salinity measurement system resistant to corrosion caused by high salt levels was developed. The salinity measurement method used is the conductivity method. The salinity value of the solution is proportional to the measured conductivity value of the solution. Conductivity measurement uses two electrodes connected to a voltage divider circuit with an AC power source to avoid electrode polarization and electrochemical reactions. The output voltage of this voltage divider circuit is proportional to the conductivity value of the solution in which the two electrodes are immersed, based on Ohm's law. This output voltage is fed into a signal conditioning circuit consisting of an amplifier, filter, and full-wave rectifier. Subsequently, an Atmega 328 microcontroller processes this data for real-time display on a TFT LCD and real-time storage on a data logger module. Testing and calibration are then carried out to obtain the relationship between the solution's salinity value and the measured output voltage, expressed as a 2nd-order polynomial function Vout = -0.0012C2 + 3.5126C + 14.194. Additionally, it is known that salinity measurement results using the conductivity method are influenced by temperature, so temperature measurement using the DS18B20 sensor is required to obtain a compensation factor due to temperature changes. The higher the temperature, the higher the measured salinity value for the exact solution measurement.

Abstract

The increasing demand for paper has significantly impacted the environment due to the heavy reliance on wood as a primary raw material. This study investigates the feasibility of using durian (Durio zibethinus) peels and corn (Zea mays) stalks as alternative raw materials for paper production, focusing on their physical characteristics. The paper pulp was prepared using the soda pulping method with NaOH. Various ratios of durian peels and corn stalks were mixed: 1:0 (A), 0:1 (B), 1:1 (C), 2:1 (D), and 1:2 (E). Results indicated that type D produced the thickest paper, while type A produced the thinnest. The highest grammage was observed in type E, and the lowest in type D. Type C showed the highest absorbency. The tensile and tear indexes were highest in type D and lowest in type C. Type A had the highest mass density, whereas type D had the lowest. The findings suggest that a combination of durian peel and corn stalks exhibits diverse physical properties, indicating their potential use as an alternative to conventional wood-based paper. This approach could reduce the dependency on wood and contribute to environmental conservation.

Abstract

This study aims to analyse the need for developing Android-based science e-books for PGMI FTK UIN Mataram students. By applying a quantitative approach through questionnaires, this research seeks to identify the needs and characteristics of students in learning science. The results of the analysis showed that 80% of the 45 respondents considered science materials, especially physics content, difficult to understand. The majority of respondents (80%) wanted teaching materials in digital format due to its practicality, effectiveness and efficiency. The very strong support (97.8%) for the development of interactive e-books reflects the urgency of this innovation in improving the quality of learning. The expected e-book is an interactive learning platform with rich multimedia features, while remaining simple and easy to use. E-book development needs to consider student characteristics, such as cognitive and affective development stages, interest in visual materials, and the need for concrete media. In addition, e-book content must be aligned with the competency standards and basic competencies in the applicable curriculum. This research provides a strong foundation for the development of innovative and effective Android-based science e-books to support learning in PGMI Prodi FTK UIN Mataram.
