The largest deposit of natural asphalt in the world is located on Buton Island, Indonesia, which is around 677 million tons. With such abundance, Indonesia should be able to supply domestic asphalt needs, even has the potential to export abroad. However, the asphalt industries in Indonesia have not been able to process effectively the natural asphalt from Asbuton rock into a better quality of asphalt. Generally, they only focuses on resizing and separating the Asbuton rock according to the specifications of filler. This situation causes Indonesia has to import asphalt from abroad. Several studies and experiments have been done previously in lab-scale to produce high yield of nanoasphalt from Asbuton by combining microemulsion technique and Ultrasonication. Here we present a conceptual plant design of nanoasphalt production to process 121.8 tons/day of Asbuton rock as the raw material and produce 190 ton/day of nanoasphalt. The economic feasibility of processes of the Plant Design is analyzed. The economic evaluation in this work involves analyzing the capital and operating costs of the process to determine the return on investment (ROI), Break Even Point (BEP), Payback Period (PP), Internal Rate of Return (IRR). The result shows that the production of nanoasphalt is relative economical with ROI, BEP, PP and IRR are 31.54%, 24.5%, 2.47%, 35.46%, respectively.
Injection molding is a method of forming a thermoplastic/ composites material that is melted by heating and then injected into a mold so that the thermoplastic material can harden.

Thermal power plants (TPPs) involve the fuel combustion activities hence are the key emission sector worldwide. Particularly, the fine particulate matter pollution and acidic precipitation in many countries are strongly associated with the emissions from coal based TPPs. In Vietnam, the power generation sector still heavily relies on fossil fuel. Coal-fired TPPs contributed 42% of the national electricity production in 2018 and are projected to increase to 53% in 2030. This study uses the emission inventory tool, an important component of an integrated air quality management system, to develop a comprehensive emission database for TPPs to provide scientific evidence for policy makers to prioritize the emission control efforts. The emissions from TPPs, including coal, oil, natural gas, and biomass based, have been quantified for 2018 and projected to 2030 taking into account the National Power Development Master Plan revised in 2016. The activity data in 2018 were collected considering the fuel and combustion technology, as well as the emission control levels of each TPP so that the appropriate emission factors can be selected from literatures for the emission calculation. The results show that out of different types of TPP, in 2018 coal-fired TPPs had the largest emission shares of all species: 95% of total 145 Gg SO 2 , 85% of total 133Gg of NO x , 95% of total 19Gg of PM 2.5 , 80% of total 29Gg of CO, 80% of total 7Gg NMVOC, 99% of 4Gg BC, and 90% of 129 Tg CO 2 . The projected emissions for 2030 show large increase in total emissions as compared to 2018: four times for SO 2 , and three times or above for other pollutants. In the next stage, this research will use the 3D modeling approach to assess impacts of the current development plan and alternative scenarios of TPPs on air quality, human health, atmospheric deposition fluxes and associated effects on ecosystem.
Drought is a natural disaster characterized by unbalanced water conditions.Land damage caused by drought occurred in Java Island precisely in Cirebon Regency, West Java. The lack of map data containing information on potential drought-stricken areas also serves as one of the factors hindering the resolution of drought problems.The creation of drought potential maps in a region can be done using remote sensing techniques (indraja) and Geographic Information System (SIG). As for identifying drought using tenik remote sensing can use landsat 8 imagery with NDVI and TCT methods. GIS can analyze supporting data in the form of rainfall maps and administrative limits so that it can present a map of potential land droughts. The results of this study show that drought with dry grade only occurs in Gegesik and Kapetakan sub-districts. Cirebon regency has a normal drought level in November 2019. November is the end of the dry phase in Cirebon Regency in 2019.
Prevention of the acid mine drainage generation is the best effort to reduce one of the environmental issues in mining activities. This effort can be done by covering sulphidebearing rocks by suitable and available rocks or materials to prevent the oxidation reaction of sulphide minerals with water and air. One of the materials that might be utilized is coalcombustion ash from the power plants, in the form of fly ash and bottom ash. It is necessary to conduct material characteristization of the ash so that the plan to form a cover layer can be carried out optimally. The test is carried out for mineralogical analysis using XRD and XRF; static geochemical tests with Paste pH, Net Acid Generation (NAG), Acid Neutralizing Capacity (ANC), Maximum Potential Acidity (MPA); and kinetic test with the free drainage column test. The test results show that FA and BA have non acid forming (NAF) characteristics so that they have the potential to be used as cover layer for potentially acid forming (PAF) material. In addition to geochemistry, geophysically FA has the ability to reduce water infiltration because it contains a lot of clay minerals, while BA has the ability to maintain moisture in the cover layer due to sandy properties of the material.
The development of architectural design has increased numerous types of irregularities in structures, one of them is a T-shape building. The asymmetrical plan structure can induce a more unstable response due to earthquake loads. Buildings are generally designed using a rigid diaphragm rather than a semi rigid and flexible diaphragm. This study aimed to analyze the effects of diaphragm flexibility on structural response such as natural period, deformation, and base shear forces. The gravity and seismic loads on the buildings were based on SNI 1727:2013 and SNI 1726:2019. The finite element software program was used for modeling and running the analysis of structure. The results reveal that the rigid diaphragm structure has higher stiffness and generates smaller story displacement and base shear force than semi rigid and flexible diaphragm structures. The flexibility on irregular structure also affects the structural mode shape significantly.
