Abstract
The use of UAV photogrammetry for three-dimensional modeling continues to be developed to produce models with high accuracy which are then used for documentation, maintenance, and development of the object being modeled. In this research a three-dimensional modeling of the National Education Museum, Universitas Pendidikan Indonesia is one of the landmarks of the Indonesian Education University campus. At the acquisition stage, taking photographs with two flight paths, namely circular grid and vertical grid so as to produce photos with oblique orientation and upright parallel to the face of the building. At the processing stage, scaling is done using field dimension data inputted on the model to produce a model that has dimensions that resemble actual conditions. From the processing results, we get a three-dimensional model that has the shape and texture in accorandce with the original conditions, but there is a large distortion in the glass object. In addition to the accuracy test analysis, there is an RMSe value of 0.278 meters in the comparison of the sizes in the model with the actual conditions

Published: March 2021

Abstract
Bandung Basin is unique because it consists of flat to mountainous areas. As in the Northen parts of Bandung Basin, the north is steeply sloped and is located in the Tangkubanparahu volcano and Mount Burangrang. Topographic variations in the Northen parts of Bandung Basin affect vegetation cover and temperature according to the height of the place. Various type in vegetation greenness and temperature can be analyzed by applying remote sensing. The aims of this study are : 1) Identification of land surface temperature in the northen area of Bandung Basin in 1990 - 2018, 2) Estimating the greenness of vegetation in the northen area of the Bandung Basin in 1990 - 2018. The method used is information extraction through multi-temporal remote sensing imagery to obtain land surface temperature and greenness of vegetation in the northen parts of Bandung Basin. The results of this research show temperature is getting hotter in the period of 1990 to 2018 while the greenness of the vegetation is decreasing, as indicated by forest vegetation, pine forests, tea plantations, grass, rice fields, and bushes increasing LST values and decreasing SR values. In contrast to agriculture, SRI values actually increase with LST. This can be caused by changes in agriculture to other land cover, or the type of plant is changes. It is recommended that the northen parts of the Bandung Basin should maintain the greenness of the vegetation to control the stability of the temperature because most types of vegetation have increased LST and decreased SRI especially in urban areas.

Abstract
The study aimed to examine environmental sustainability practices among youths in Muallim District, Perak, Malaysia. This study applied a quantitative method comprising questionnaires with 400 youths aged 19 to 40. A simple random sampling method was used to divide the respondents into groups of two. Most variables (including knowledge, values and skills) were at high levels, but the environmental sustainability skills variable was only at a moderate level, with a mea score between 2.34 until 3.66. The findings also revealed a strong significant relationship between knowledge, values and environmental sustainability skills and environmental sustainability practices (p<0.05). The regression findings showed that environmental sustainability knowledge, environmental sustainability values and environmental sustainability skills contributed a total of 38.3 percent of variance change to environmental sustainability practices, with environmental sustainability knowledge being the greatest contributor at 31.5 percent, environmental sustainability at 5 percent and environmental sustainability skills at 1.8 percent (R2 =.383, F(1, 339)=81.846, p<.05). This indicates that overall environmental engagement practices were influenced by individual sustainability skills. In fact, environmental knowledge not create awareness among youths to apply practices that lead to environmental sustainability; rather, the skills possessed and acquired by youths can lead to their engagement in environmental sustainability practices.

Published: March 2021

Abstract
Tumor-treating field (TTF) therapy has been receiving attention as a new minimally invasive treatment for cancer. In this treatment, an alternating electric field applied to target cells inhibits cell division by a dielectrophoretic force acting on chromosomes and microtubules. Previous studies have shown that an extremely weak electric field of only a few volts per centimeter interferes with chromosome migration and spindle formation. However, the therapeutic range of TTF treatment is still limited. To increase the efficacy of the treatment, the electric field to the target cells must be optimized. Therefore, the aim of this study was to investigate the effect of the electric field frequency, cell morphology, and electrical properties on the outcome of TTF treatment. Three-dimensional finite element models of a sphere and dividing cell were developed, and the distributions of the electric field and dielectrophoretic force were calculated.

Published: March 2021

Abstract
In order to enhance the heat transfer performance of heat tubes, porous media are often sintered into them. This increases the heat transfer area due to the surface area being increased by the porous media. Our The test apparatus consisted of a double tube structure, and the length was 150 mm. Previous experiments have shown its usefulness and revealed that a breakthrough in the heat exchanger has occurred. For example, air heated to 200 °C and water cooled to 1 °C flowed inside and outside the heat tube, respectively. In tests with conventional heat tubes, air was discharged at 150 °C through the test section. However, in tubes filled with 50 mm of porous medium, air was discharged at 5 °C. In other words, a conventional tube would need to be 100 times as long. We have already proposed a correlation that can accurately predict the heat transfer coefficient regardless of the pipe diameter and filling length. On this study is about understanding the mechanism of pressure drop and constructing an equation, and We have established a method for predicting the pressure drop of a porous body within approximately ±10%.

Published: March 2021

Abstract
Excessive waste production is often happening in the inefficient use of resources in manufacturing. There is still some excessive waste found in the electronic components company as a case study. It resulted from the careless use of resources and indirectly weakness their market positioning. The purpose of this paper is to present an implementation of a lean manufacturing process to reduce waste. This study aims to analyze and reduce the waste that occurs using lean manufacturing approaches. The value stream mapping (VSM) and waste relationship matrix (WRM) were applied to describe and to analyze the production flow of waste. Then, a waste assessment questionnaire (WAQ) is used to determine the percentage of waste that occurs. Value Stream Analysis Tools (VALSAT) is used for complete mapping tools. Three methods are considered for determining the feasibility, namely, net present value, internal rate of return, and profitability index. Base on analysis, we choose on the 3rd largest waste to be improved. According to the data analysis, it is found that increasing the number of production machines, carrying out appropriate maintenance activities, increasing training and supervision, and adding work facilities are recommendations for the improved production process. The proposed guidance seems to help the company reduce the seven waste and increase unit production. It is expected that the production process will be more effective and efficient.

Authors: Minn Y , Hassan A 
Published: March 2021

Abstract
To ensure successful implementation of cyber-physical systems, industries require computer networks to be protected from malicious attacks. Despite various intrusion detection techniques being proposed by researchers, computer networks are still vulnerable to attacks. As new attacks becoming more complicated, more research is needed to develop more effective and reliable intrusion detection schemes. This study investigated the exponentially weighted moving average control charting technique for detection of malicious denial of service (DoS) trafic and compared it with artificial neural network (ANN) based scheme. Eight features from the Benchmark KDD Cup99 computer network datasets were extracted and their respective ARL1 and false alarm rate were evaluated. The results suggest that EWMA technique is effective only for selective features and the ANN-based scheme is relatively consistent in handling variability in traffic data. This study opens new opportunities for further investigation to enhance performance of the proposed schemes.
