Published: June 2019

Abstract
According to National Census of Fatal Occupational Injuries survey conducted by the U.S. Bureau of Labor Statistic in 2015, there were 4836 workers killed on construction sites due to illness and fatalities, 9% injuries were due to the exposure to the hazardous environment. Wireless Sensor Networks (WSNs) is one of the technologies used to access information from the environment and sent to the computer for analysis, thus reducing exposure to the hazardous environment. However, the state of danger is not yet known to the worker directly. Fortunately a mobile application can overcome this problem by receiving notification from the sensor device. In this paper, we propose a mobile application that can receive notification from the sensor device. We design our application to communicate to the sensor device that connected to the server. Our application can receive notification if there is an alteration from sensor data such as change of normal status to dangerous status or vice versa. Notification delivery was sent by using Firebase Cloud Messaging (FCM) to send notifications to Android. In the implementation, the application can receive notification of change of status sensor data equipped with sound when notification received.

Abstract
Cancer is still a significant problem for people today because it is one of the biggest causes of death in the world. Based on GLOBOCAN data in 2018, breast cancer accounted for the world’s largest cancer mortality rate in women by 6.6% with total deaths amounting to 626,679 from 2,088,849 cases of cancer in the world. The high mortality rate of breast cancer is caused by the lack of effective early detection of the disease. MicroRNAs play an essential role in regulating cell division cycles, apoptosis, senescence, migration and cell invasion, and metastasis. The expression of microRNA in breast cancer shows a pattern compared to normal breasts, thus indicating its role as a potential diagnostic marker. Cancer classification using microRNA as a feature has been done in previous studies using Neural Network Backpropagation, however without optimization and tuning parameters. In this paper, we investigated the best optimization algorithm and tuning parameter of neural network backpropagation for cancer classification using microRNA feature. The optimization algorithms were Gradient Descent, Momentum, AdaGrad, AdaDelta, RMSProp, and Adam. The result of the experiment showed that Adam and RMSPop optimizer produced high accuracy which reached 98.536% and 98.54762% accuracy.

Abstract

Rhizophora apiculata is species in mangrove vegetation. The mangroves leaves were the water-storage type. Induction of callus from the leaf of R. apiculata faced problems, i.e., browning phenomena and exudates. This research aimed to evaluate the production of exudates and their correlation with the browning of explant and to identify kind of compounds of exudates. The leaf that is used as explants was divided into the base and tip section was grown in Murashige and Skoog (MS) medium with the addition of NAA 1 mg/L, BAP 0,3 mg/L, and activated charcoal 12 g / L. The treatments included 24 hours placed in the dark and 24 hours placed under light, 16 hours placed in the dark and 8 hours under the light, 8 hours placed in the dark and 16 hours under the light; the treatments were repeated four times. Respond of explants were descriptively observed, while the exudates were analyzed by Benedict test. The results showed that light treatment could induce callus formation while 24-hour dark treatment could reduce browning. The novelty of this research lies upon the process of browning prevention using light duration treatment. Therefore, browning could be prevented, and mangrove culture could successfully produce callus. Not at all explants produced the exudates. Light treatment can be used to avoid exudates production. Some of the exudates consisted of carbohydrates. Nevertheless, another one consisted of a salt solution. These exudates made a disturbance in callus initiation of R. apiculata.
