Creep mechanism is an essential mechanism for material when subjected to a high temperature and high pressure. It shows material ability during an extreme application to maintain its structure and properties, especially high pressure and temperature. This test is already done experimentally in many materials such as metallic alloys, various stainless steel, and composites. However, understanding the creep mechanism at the atomic level is challenging due to the instruments limitation. Still, the improvement of mechanical properties is expected can be done in such a group. In this work, the creep mechanism of the nanocrystalline Cu-Ni alloy is demonstrated in terms of molecular dynamics simulation. The result shows a significant impact on both temperature and pressure. The deformation supports the mechanisms as a result of the grain boundary diffusion. Quantitative analysis shows a more substantial difference in creep-rate at a higher temperature and pressure parameters. This study has successfully demonstrated the mechanism of creep at the atomic scale and may be used for improving the mechanical properties of the material.

Distilled water in the laboratory is highly important since it is a basic requirement in the lab work and/or research. The large use of distilled water in the Faculty of Mathematics and Natural Sciences University of Lambung Mangkurat (FMIPA ULM) obliged to depend on its own by providing the equipment to produce distilled water. The efficiency of water is low during producing one liter distilled water due to 35 liters is needed. Several studies have conducted focusing on the energy efficiency and the use of alternative energy in the distilled water production. Efficiency is not only limited on the heating energy sources, but also the cooling component. One of the attempts is modifying the cooling water circulation in the distillation equipment. It aimed that the cooling water is not wasted but is returned to the circuit. In this study, a cooling water circulation modification was carried out by adding a radiator set, submersible pump and storage tank. The distilled water produced from this circuit will be compared with distilled water from distillation equipment without modification. The parameters compared which are: temperature, volume, electrical conductivity and pH. Our research results show that the modified distillation equipment series is feasible to apply since the electrical conductivity of the resulting distilled water is lower than before modification process and also the sediment attached to the boiler wall is formed slower than the distillation equipment without modification. With the need for a lower volume of raw water, a series of modified distillation equipment is also suitable for use in the dry season or during water distribution is not smooth.

Technological processes for modification of materials, deposition, and prevented fumes in the pyrolysis processes are used gases materials in the medium with vacuum pressure or atmospheric air pressure. Therefore, it is essential to understand heat flow transport for designing an eﬃcient reactor or find the substrate's excellent position in the reactor or furnace for growing materials. We evaluated the energy transfer phenomena in the form of temperature distribution and heat flow for various heating sources for the gases and solid materials by Gauss-Seidel equation. The thermal conductivity coefficient (k), number of heating sources, and position of heating sources show an essential parameter for transmitting the distribution of the heat. For high k value shows efficiently for heat transfer at low temperature due to the atom's position close each other. The heat also affects to the phonon and lattice vibration like a wave which successfully shows these phenomena in this study.

Climatologically, Aceh is influenced by global, regional, and local phenomena strongly influenced by the hilly mountain topography. Aceh is also surrounded by Indian Ocean in the west, Malacca Strait in the east and Andaman Sea in the north that making climate conditions more varied. The old season zone is not compatible to explain this condition. This paper makes an updated analysis by combining the observational and satellite data for rainfall activity explanation. We use k-means clustering based on the analysis of blending data between observation data and satellite imaging that produces more specific and updated season zone (ZOM). The clusters obtained are newly season zones that provide more specific mapping for dry and rainy season information. The updated season zone of 15 ZOM clusters based on k-means can figure a clear variation that means the accuracy of difference rainfall value can be more precise. From this research, the updated season zone can provide effective planning about strengthened from various government sectors in the future that can give a better policy to the public community.

Activated carbon is a carbon with an amorphous structure arranged in a parallel hexagonal ring. In this research, activated carbon has been synthesized from sago waste. The purpose of this research was to synthesize activated carbon with ZnCl2 activator and investigate the effect of ZnCl2 activator concentration on the characteristics of activated carbon. Synthesis of activated carbon was carried out with the following stages: dehydration, carbonization, silica extraction with NaOH and ZnCl2 activation with variations in concentrations of 5, 15 and 20%. The characterization of activated carbon was carried out by analyzing the crystal structure and morphology, which was conducted using a scanning electron microscope and x-ray diffractometer. The characterization results showed that the best activated carbon was synthesized from 15% ZnCl2 activator due to its amorphous structure with a relatively small pore size of 2 µm.
