Melting point, particularly metal, is one of the important data for many applications. For developing new materials, adequate theories for melting point are very crucial. The determination of melting point using the popular phase-change curve method is very easy but usually overestimate. In current work, we determine the melting point of a pure metal (iron) using the method of solid-liquid phase coexistence. For this goal, molecular dynamics simulation was applied to obtain data of trajectories of atoms. Simulation (LAMMPS) and data analysis (OVITO) procedures are strictly applied to obtain the accurate melting point of iron based on the obtained trajectories data. For initial structure design of simulation, we used the ATOMSK program. The melting point of iron obtained using the phase change curve (PCC) method is about 2750 K < TPCC < 3250 K and using the coexistence phase (CP) method is TCP = 2325 K. A more accurate calculation needs to include defects factor in the simulated material and calculation. In this research we use the Morse potential to represent all of the atomic interaction among atoms of Fe material.

There have been no reports of the simultaneous application of natural fillers, such as magnetite and natural zeolites, to increase the strength of composites containing silica (SiO2) fillers as reinforcing fillers in natural rubber. This study has investigated the effect of magnetically modified natural zeolite on nanosilica-reinforced natural rubber composites that include a mechanical characteristic like human tissue. We use technical specifications rubber (TSR) SIR 20 with nanosilica reinforced fillers and Titanate coupling agent (TCA) as fillers and elastomer binders. The results showed that the nanosilica-zeolite-magnetite (Fe3O4) mixture had an influence on strength and stiffness and could be a substitute filler. The precursors made with some variations include the optimization of filler and the optimization volume fraction of nanosilica. Mechanical characteristics of different human body part tissue were compared to the control samples and have similar mechanical characteristics with internal human tissue characteristic. Based on these results, nanosilica fillers combine with magnetically modified zeolites and titanate coupling agents, potentially as an alternative filler to replace carbon black, and are applicable for synthetic muscle replacement cadavers with a customized formula.

We study the performance of the quantum Lenoir engine using single-particle confined within the cubic potential. In 3D potential structure, particles degenerate into multiple states at identic energy level which occurs on the excitation state of the particles. Deliberating the degeneration effects, the confined particle has possibility to produce more energy efficiency as engine’s working substance. The particle is able to freely move in three directions of x, y, and z-axis simultaneously, which gives three degrees of freedom to the particle in the cubic potential. By limiting to two eigen states, a basic explanation to the condition of the particle was provided. The efficiency of 3D quantum Lenoir engine is better than the classical model of the Lenoir engine despite the similarity in the formulation. Moreover, we also consider the efficiency comparison between the 3D model, with some state modifications, and the 1D efficiency of the quantum Lenoir engine. As expected, degeneration of the particle’s states plays a role in the enhancement of the quantum Lenoir engine’s efficiency. Moreover, we also derived the power output of the 3D quantum Lenoir engine. Thus, this study clearly gives a sight of the performance of quantum Lenoir engine model in the 3D manner.

The supercapacitor electrode has been synthesized using activated carbon from cocoa pods. Activated carbon was prepared by first drying the raw materials under the sunlight and followed by oven drying, pre-carbonization, milling, sieving, and chemical activation with 0.3 M and 0.4 M KOH solution. After chemical activation, the activated carbon was printed into pellet form, carbonized at a temperature of 600 °C, followed by physical activation at a temperature of 700 °C for four hours before polishing. We found that the optimum conditions are 700 °C and 0.4 M. The density of the obtained carbon electrode is 0.810 g/cm3. The SEM micrographs show the formation of pores with a diameter of 0.44 μm and 0.98 μm. The carbon content in the electrode sample measured using electron dispersive spectroscopy is 91.49%. The XRD data shows that the carbon electrode is amorphous with a diffraction angle (2θ) at 23.569° and 44.781°. The optimum specific capacitance of the supercapacitor is 140.2 F/g obtained for the sample activated for 2.5 hours.

− North Maluku, especially Halmahera Island is part of the framework of Indonesia's complex tectonic system and has a high tectonic activity. This area has the meeting zone of the Eurasia plate, the Pacific plate, the Indo-Australian plate and other small plates such as the Philippine plate. As a result of geodynamics, the research area with high seismic activity is due to many geological structures such as anticlines, synclines, upward faults, horizontal faults and normal faults due to plate activity in this area. One of the methods t hat can be used to identify the faults and their types is the gravity method. this study was using the gravitational observation data of the Topex satellite with an area of 3,891.62 km 2 in the form of Free Air Anomaly (FAA), which is then corrected by bouguers and field correction yields a complete Bouguer Anomaly (ABL). Regional and residual anomalies show the good correlation with the geological map of the study area in delineating the distribution of faults with a range of positive anomalies ± 187 mGal and negative anomalies ± -14.8 mGal. Second Vertical Derivatif (SVD) anomaly analysis shows that the distribution of faults in the study area is a type of normal fault.

− Geoelectric research has been carried out in Megal, Blora Regency with the Wenner and Schlumberger configuration resistivity geoelectric method. The purpose of this research is to provide information about the subsurface layer as a potential point for groundwater drilling which has variations in rock lithology. The geoelectric method works by utilizing the propagation of electric current located below the surface so that data is obtained which is processed using Res2dinv software with the inversion method, and interpreted to identify groundwater aquifer zones in Megal, Blora Regency. The results of the Wenner configuration show up to a depth of 17.2 meters but the data does not find groundwater sources. Meanwhile, the results of the Schlumberger configuration showed up to a depth of 31.5 meters and an anomaly was found so that drilling was carried out to obtain soil layer data.

Research has been conducted on the level of pollution caused by Leachate in shallow groundwater around Kebon Kongok landfill, Gerung, West Lombok. This research was conducted considering that water has many benefits in daily life, so it is important to know the quality of the water consumed. The research used experimental methods by analyzing physical parameters (Temperature, conductivity, pH and TDS) and chemical parameters in the form of heavy metal content (Pb, Fe, Cu and Mn). The results of physical parameter tests mostly show that the quality of shallow groundwater is still within the safe quality standard, there is 1 shallow groundwater point that is polluted due to the close proximity to the leachate. Chemical parameters indicate that the content of heavy metals is mostly well below the quality standard, except Cu metal is detected at 0.029 mg / l and Mn metal 1,457 mg / l at a distance of 50 m.KEYWORDS : Leachate; Shallow Water; Physics Parameters; Chemical Parameters
