The synthesis of nano-silica gel based on magnetic minerals from the coastal sand and river sand of Lombok Island has been carried out. The synthesis method used is sol-gel with HCl acid and NH4OH base. The results showed that nano-silica based on coastal sand has a greater silica content than nanosilica based on river sand. The morphology of nanosilica based on coastal is granular with a smaller grain size of nanosilica based on coastal sand compared to nanosilica based on river sand. To a temperature sensor, nano-silica based on coastal sand has a larger coefficient when compared to nanosilica based on river sand. This indicates that nano-silica based on coastal sand has better physical properties as a temperature sensor than nanosilica based on river sand.

This study aims to analyze silica's morphological characteristics and electrical properties based on the river and coastal sand. Iron samples were taken from Sompang river sand, East Lombok and Coastal Sand from Gading, Mataram City. The silica was synthesized using the sol-gel method with a sintering temperature variation of 100 to 175 ℃. Morphological characteristics samples analysis was done using SEM-EDX. The electrical properties of iron sand included measuring the dielectric constant using the parallel plate method. Furthermore, the resistivity was measured using the two-point probe method. In the silica-based on river sand sample, the resistivity value was inversely proportional to the sintering temperature. In contrast, the resistivity value of silica based on the coastal sand sample was directly proportional to the sintering temperature. Silica-based on river sand has a resistivity of about 7.1'104 Wm at a sintering temperature of 100℃ and 3.5'104 Wm at a sintering temperature of 175℃. Silica-based on river sand has a resistivity of about 1.8'104 Wm at a sintering temperature of 100℃ and 7.1'104 Wm at 175℃. This research is a preliminary study on the electrical properties of natural sand-based silica to improve understanding of the physical properties of silica to be used in technological applications, such as sensors. Furthermore, the dielectric constant value in the river sand sample was directly proportional to the sintering temperature. However, the dielectric constant in the coastal sand sample was inversely proportional to the sintering temperature. Silica-based on river sand has a dielectric constant of about 1.02'102 at a sintering temperature of 100℃ and 1.18'102 at 175℃. Silica-based on coastal sand has a dielectric constant of about 1.97'102 at a sintering temperature of 100℃ and 1.15'102 at 175℃.

This study aims to synthesize hematite based on magnetic minerals from the Geres River sand, which is used as a heavy metal absorbent. The Geres River iron sand-based magnetic mineral has a high iron content that can be extracted to produce hematite. The synthesis method used is the coprecipitation method. Mineral content and morphology were characterized using SEM-EDX. Hematite functional groups were analyzed using FTIR. Water quality analysis was based on physical parameters (conductivity and TDS) using a TDS meter, while the heavy metal content of Mn before and after filtration was analyzed using AAS. Based on SEM-EDX analysis, the average grain size of hematite was (0.99 ± 0.20) µm with the highest element content of Fe (72.90 ± 0.28) %. Functional groups are formed at a wavelength of 951.72 cm-1, which shows the Fe=O double bond. After filtration, hematite was able to reduce the heavy metal content of Mn by 19.58%, followed by a decrease in conductivity by 12.95% and a decrease in TDS by 15.18%. This shows that hematite is effectively used as a heavy metal absorbent. Through this research, it is hoped that the community will not only use iron sand magnetic minerals as building materials but also process them into more useful materials such as hematite, which can be used as a heavy metal absorbent.

Integration of Islam and Science in Physics Learning: A Case Study of The First Law of Thermodynamics Meiliyadi, Lalu Ahmad Didik; Arizona, Kurniawan; Efendi, M. Harja; Wahyudi, Muh.; Damayanti, Isniwana

There is a strong belief in society that religion and science are two entities that cannot be reconciled. They are separate from one another and have their domains. Integration is the keyword for discussing the relationship between science and religion. The integration of science and religion can be achieved by taking the philosophical core of fundamental Islamic religious sciences as a paradigm for future science. This integration process can be seen as the Islamisation of science as part of the Islamisation of civilization. One example of this integration can be seen when discussing one branch of science, namely physics, about Islamic studies. In this case, one topic is taken from the First Law of Thermodynamics. Thermodynamics is the science that discusses heat and its changes. Heat and its changes have been explained in the Qur'an, as stated in the words of Allah SWT in Surat Al-A'raf, verse 52. For example, the source of heat energy has been explained in Surat Yaasin, verse 80, and Surat Yunus, verse 5, which state that fire is the source of heat. In its transformations, according to the First Law of Thermodynamics, this heat energy can change into changes in internal energy and work. Changes in internal energy occur due to an increase in the system's temperature after heat energy is added, while work arises due to a change in the system's volume after heat energy is added. As an illustration of the First Law of Thermodynamics, let us imagine a balloon. If the balloon is heated, the air particles inside the balloon will experience an increase in temperature. It is the nature of a particle that when its temperature increases, its energy also increases. This increase in energy is what we call an increase in internal energy. Since the internal energy of the gas particles inside the balloon increases, there will be more energy for the gas particles inside the balloon to move and collide with the walls of the balloon. As a result, the volume of the balloon will increase, and work will be done. If the elasticity of the balloon can no longer withstand the collisions of the gas particles inside it, the balloon will burst.
