Authors: Lukiyansah E , Tambunan M P , Marko K
Published: September 2020

The lake’s catchment area is one of the objects of land use conversion as a space for community needs. The boundary of the Lake Rawa Besar has been widely used by the surrounding community to carry out activities. Human activity and land use around lake shorelines can affect water quality. This study aims to investigate the pattern of spatial distribution of Lake Rawa Besar water quality and its relationship with land use within the lake shoreline. Water quality was tested based on the insitu sampling method in 30 samples evenly distributed in the water body and laboratory testing based on 6 water quality parameters such as turbidity, BOD, total phosphate, total solid, pH, and nitrate. Water quality is measured based on the water quality index level of WQI (Water Quality Index) and interpolated using the IDW method. Large-scale land use is used from digitizing large resolution images and potential sources of pollutants obtained from field observations. The results showed that the water quality in water bodies was almost evenly distributed with mild polluted criteria. Land use in the form of domestic activities affecting the quality of water in the Lake Rawa Besar is characterized by high turbidity and BOD values, while the total phosphate, total solid, nitrate, and pH value is low. The high correlation between turbidity and BOD which is impacted from land use concluded that the poor quality of the lake’s water was caused more by organic waste.

Natural disasters due to bad weather make the need for weather information increase. The impact of severe hydrometeorological events has caused many casualties and significant damage to property and infrastructure, with adverse economic consequences for the people that can last for years even greater for future climate change, because almost all of the bad weather and climate events are projected to change in frequency, intensity, spatial area, duration and time. The availability of weather information so far turned out to be not enough to reduce the impact of bad weather phenomenon, the accuracy of forecasting and early warning information must be followed by public knowledge of what must be done to respond to this information. The implementation of an impact-based weather information dissemination system elaborates on the delivery of the impact of a hazard to individuals or communities at risk. A series of Covariance Analysis analyses were carried out using the SPSS application to investigate differences in intended perceptions and actions between phenomenon-based weather warning recipients and impact-based weather warnings, by controlling several relevant demographic variables, for example, gender, age, education, and domicile/residence. The results of an analysis of the community response assessment of weather forecast information and early warnings showed that respondents who received impact-based warning information felt it was much easier to understand the possible effects of bad weather, more trust that the potential impact would be more threatening, and was more concerned about the effects of bad weather compared when respondents received phenomenon-based warning information. There is no significant difference for the respondents to take further action on the information provided and the higher the level of education and the more vulnerable the region is, the more public the response.

Published: September 2020

Tunable diode laser absorption spectroscopy (TDLAS) is a kind of gas concentration measurement technology with high precision widely used in the detection of methane (CH4). Compared with the near-infrared absorption band, CH4 molecule has greater absorption intensity in the range of mid-infrared absorption band. Therefore, the TDLAS performance can be greatly improved when the mid-infrared quantum cascade laser (QCL) is adopted as light source when detecting CH4 concentration. As an important parameter, the effect of modulation factor on the second harmonic signal was analyzed, and the optimal value of modulation factor was obtained to be 2.2 by simulation. In addition, both the TDLAS measurements of CH4 concentration in the range of near-infrared and mid-infrared were simulated and analyzed under normal temperature/pressure and troposphere environment respectively. The results show that the sensitivity of the detection of CH4 gas in the mid-infrared band of 7.6 μm is greatly improved relative to the absorption band of 1.6 μm in the near-infrared.

Published: September 2020

A combination of seismic refraction survey, electrical resistivity method and integration with borehole method has been used for ground exploration to study the slope surface failure along the study area at Kayangan Height, Selangor. This study focuses on investigating the possible cause of the slope failure at the area. By necessity, non-destructive method like electrical resistivity test is the most suitable method as this method can determine the subsurface water conditions. Meanwhile, seismic refraction test is able to determine the type of subsurface layers and level of bedrock. Seismic refraction test can guide the borehole drilling works which can provide borelog data. Based on the study, seismic tomogram and 2D resistivity imaging results provide complementary information to each other. The existing geotechnical borehole logs refined both seismic and 2D resistivity results. Therefore, the study shows that the electrical resistivity test, seismic refraction test and borelog data in combination, could be an effective tool and cost effective for slope failure investigation.

Indoor air such as house, shopping complex, hospital, university, office and hotel should be monitor for human safety and wellbeing. These closed areas are prone to harmful air pollutants i.e. allergens, smoke, mold, particles radon and hazardous gas. Laboratories in university are special room in which workers (student, technician, teaching/research assistants, researcher and lecturer) conduct their works and experiment. The activities and the environment will generate specific air pollutant which concentration depending to their parameters. Anyone in the environment that exposure to these pollutants may affect safety and health issue. This paper proposes a study of development of a cloud-based electronic nose system for university laboratories air monitoring. The system consists of DSP33-based electronic nose (e-nose) as nodes which measure main indoor air pollutant along with two thermal comfort variables, temperature and relative humidity. The e-noses are placed at five different laboratories for acquiring data in real time. The data will be sent to a web server and the cloud-based system will process, analyse using Neuro-Fuzzy classifier and display on a website in real time. The system will monitor the laboratories air pollutants and thermal comfort by predict the pollutant concentration and dispersion in the area i.e. Air Pollution Index (API). In case of air hazard safety (e.g., gas spills detection and pollution monitoring), the system will alert the security by activate an alarm and through e-mail. The website will display the API of the area in real-time. Results show that the system performance is good and can be used to monitor the air pollutant in the university laboratories.

Diabetes is an affecting people disease nowadays. Over 246 million people worldwide with a majority of them being women had been affected by diabetes. According to the World Health Organization (WHO), by 2025, this number is expected to increase to over 380 million. The disease has been ranked as the fifth deadliest disease in United States with no imminent cure in sight. Along with the increasing of the information technology and its continued advent into the medical and healthcare sector, the cases of this disease and the symptoms are well documented. This paper aims at finding the best performance by four classification algorithms, which are Naive Bayes, Simple Logistics, REPTree, and Sequential Minimal Optimization (SMO). Model testing on 200 tuples with 9 attributes in the diabetes dataset revealed that Naive Bayes achieved highest accuracy of 85%. To improve the overall accuracy, it is necessary to use more data set with larger number of attributes and use a better feature selection method in future works.

Conventionally, the evaluation of cognitive and psychomotor ability performance is typically based on self-writing reports. However, such assessment was unable to measure the actual performance during the task execution. Furthermore, the performance results perceived by the instructor is mainly subjective. For an alternative solution, a new approach is proposed to acquire brainwave signals (i.e. electroencephalogram (EEG)) during task performance. The application of EEG offers a promising approach in evaluating skill abilities at physiological level. Hence, a task related to the assessed skill needs to properly design to ensure the induced EEG signal is reliable for performance evaluation. With the aid of Graphical User Interface (GUI), the time frame of each response can be capture and recorded. Therefore, this paper presents the development of task assessment in evaluating the performance of cognitive and psychomotor abilities based on EEG signal.

Data or information now is not only presented in text, but can also be presented in other forms for example in the form of images. Still image data and moving picture require storage which is much bigger than the text data. As a consequence, we need a method that can speed up the process of indexing and retrieving digital images as well as to reduce storage needed. So increasing data in the form of digital images does not reduce the speed and performance of computers and image data transfer in the internet. In this paper, we try to explore the JPEG image which is currently considered as an international standard for images in WWW. Most of the images currently stored in a media that we use frequently or on the internet are in JPEG format. This JPEG format has many advantages compared to other formats one of the advantage of JPEG is the size smaller compared to other such as PNG, and TIF. Therefore, JPEG has a very important role in saving storage without reducing quality of image itself. The research was carried out to determine the effectiveness and speed of retrieving natural images and artificial images using the CBIR method, research using no less than 5,000 images, and applying queries from 50 to 80. The results showed than in terms of effectiveness, images artificially better than natural images while natural speed is better. On the hand, speed of retrieving of natural images much better compared to the artificial images.
Cervical Cancer Classification Using Image Processing Approach: A Review

At present, Cervical cancer is the second most common cancer among women around the world. This cancer develops in the cervix; which is the entrance to the uterus. Most of the time, hospital doctors are facing difficulties in identifying cancer cells because the nucleus is sometimes rather difficult to see with the naked eye. Normal cells nuclei are smaller than abnormal cells nuclei. Abnormal nuclei are larger, which sometimes cannot be precisely identified by classifying stages of cervical cancer with the naked eye. This is because each doctor has a different perspective to monitor the classification of cancer stages by observing the nucleus without precisely reducing the size of the classification accuracy. Lately, many researchers have proposed methods for detection and classification of Pap smear images to diagnose cervical cancer. This approach can improve detection and classification accuracy, resulting in better results with accurate data balance and samples. Some patients are found to be in Stage 2 but after retesting they are actually in Stage 4, where the chances of recovery are very low. This is because doctors cannot find the right balance data and unable to take samples properly. This article discusses a comprehensive review of cervical recognition based on segment core and classification.

Face aging or age progression is a prediction on how a person looks at the future. Face aging image-to-image translation is a process of translating an image of young people to their older version or vice versa. The need for a paired training dataset to train the generative adversarial networks (GANs) is a major problem with face aging image-to-image translation. Nowadays, there is a method where an unpaired training dataset can be used to do an image-to-image translation. CycleGANs is a GANs extended methods where there is no need for paired training dataset to train the CycleGANs. From the result, it shows that CycleGANs can do face aging image-to-image translation without using the paired training dataset.
