Abstract
El Nino is one of the natural phenomena that have a significant influence on the weather, causing a longer dry season in several regions of Indonesia, one of which is the city of Lampung. One way to anticipate a long drought is to predict rainfall, by looking at the intensity of the rain. This paper proposes rainfall prediction using a recurrent neural network. Weather variables used to predict rainfall include air humidity, wind speed obtained from BMKG stations, and SOI index obtained from the NCDC website in the past 10 years. Weather data will be interpolated and extracted to find the maximum weather value per 4 weeks, the next step is overlapping, after which the data segmentation and normalization become 0-1 to make the data values not far adrift. The results showed the prediction of rainfall with a vulnerable 4 weeks using the Recurrent Neural Networks method produces an accuracy of 89.53%.

Abstract
Railway axle and railway bearing are critical railway components. It is needed a method to analyse them. In this work, static and dynamic analysis are presented. Static analysis is presented by analyzing the design of railway axle through finite element analysis (FEA). Dynamic analysis is presented by analysing the outer race fault of the railway axle bearing based on vibration analyses. Initially, a laboratory-scale of wheel-set test-rig was designed using 3D computer design, then, the design was analysed the shear stress and deformation by FEA. Based on this design, the laboratory wheel-set test-rig was manufactured for conducting dynamic experimental tests. The vibration responses obtained in the tests were then analysed using fast Fourier transform (FFT) and Hilbert-Huang transforms (HHT). The results show that the stress and the deformation are small enough. Therefore, the design can be applied. In the vibration analysis, EMD process provided good results for analysing signals.

Abstract
The use of electric motors of the industrial world is as a motor for production equipment. One example of using an electric motor is a conveyor. The conveyor has a long operating time. Conveyors can move objects from one place to another. Therefore, the condition of the conveyor machine must be good so that there are no operational errors. Errors in conveyor operation can result in delays in the production process. From these problems, research is made on a controller and monitoring of electric motors on the conveyor based on current parameters. This electric motor monitoring is based on Programmable Logic Control. This system is designed by utilizing a Current Transformer to measure the current in each electric motor. This current condition detects the condition of the electric motor in real time. If there is a change in a current that is not in accordance with the normal current, the system will detect a disturbance. This system can also control the direction of motor rotation. This system can inform all forms of disturbances to electric motors in the form of indicators and graphs of current movements in real time.

Abstract
The lighting system is one of the great considerations in the eco airport buildings concept. The buildings are usually designed applying transparent-material-covered walls to get the advantages of natural and artificial lighting combinations to optimize and save the consumed energy. This research proposes the use of a fuzzy logic method to control the artificial lighting in the airport passenger waiting room to obtain effective and efficient lighting energy consumption. Using LEDs as lighting devices, the lighting areas are divided into several rectangle zones to simplify the adjustment. For every zone, LEDs are divided into 4 groups, 2 groups are on the upper side and the others are on the lower side. Each group consists of 2 sets of light lamps and placed between the diagonal-adjacent sensors line. Light sensors are placed on each side of the zone to obtain the optimal control result. The LEDs group will be only affected by the two adjacent sensors that flank them diagonally. The result showed that the LEDs current supply controlled by fuzzy that applied to one zone can give sufficient illumination as the IATA’s requirement which is between 200 – 300 lux on the floor level.

Abstract
LoRa is a long-range, low-power, low-bitrate communication technology that is a major component of the Internet of Things (IoT). In realizing smart cities, many environmental parameters are observed in decision making that supports sustainable development. LoRa is an alternative to wireless communication from wifi and GSM networks which are more power-consuming. The use of many sensor nodes that are distributed in areas with difficult access to electricity requires low power usage. The use of low-power LoRa has the disadvantage of slow transmission speeds. Although environmental monitoring based on specific parameters such as temperature, humidity, gas, pH, etc. has been widely applied, visual environmental monitoring is necessary. In monitoring volcanoes, visual field inspections are needed to support decision making. Monitoring can be done periodically based on time. The LoRa Ra-02 module is a Lora module that is cheap and widely available in the market. In this research, a study on the potential use of the Lora Ra-02 Module for low-speed image transfer applications was conducted.

Published: March 2021

Abstract
The urinal system, with the automatic watering system (flushing), has been widely applied in several public places in Indonesia. Still, the system sometimes does not meet Indonesian habits, especially for a Muslim, as well as less environmentally friendly. For example, it is not fitted with watering facilities (flushing) to clean vital organs and consider the sufficient (not excessive) volume of water. Another essential function is monitoring the availability of water supply and the urinal itself so that it can help the maintenance with simultaneously monitor the availability. Therefore, this research aims to design an environmentally friendly urinal system. In this study, the design and development of IoT-based flushing automation systems employ HC-SR04 ultrasonic sensors, YL-83 as a detector, and ESP8266 wifi module connected to an android-based mobile phone. The urinal flushing automation system is designed with an Arduino Nano Microcontroller capable of detecting someone who will urinate and provide sufficient watering to clean it. The test results are carried out on the effectiveness of distance detection, the adequacy of water discharge, and monitoring of the availability of water. The test results are also compared with a similar type of commercial urinal system. The complete results will be described in the full paper.

Authors: Ma’arif Faqih , Gao Zhengguo , Li Feng 
Published: March 2021

Abstract
This paper investigates the compressive strength of concrete in a 3-dimensional contact problem using the Discrete Element Method (DEM). This method was chosen because it can simulate the development of a single fracture up to massive fragmentation, including cracks pattern and coalition. The experimental test consisted of four cubes with 150x150x150 mm in dimensions, the constant of axial load applied to each specimen of 0.05Po up to 0.70Po. The data analysis has been carried out in Discrete Element and opensource three-dimensional code (YADE). The spherical Particles were used to the material models of concrete cubes. The pulse velocity parameter proposed to determine the behavior of the material during loading. The DEM and pulse velocity results illustrate the conformity of the relationship between stress and strain, deformation characteristics, and compressive strength of concrete.
Heat Transfer Optimization of end Winding Rotor Generator by the Use of Modified Axial Spacer: A Case Study

Published: March 2021

Abstract
This paper presents a case study of a rotor fault occurring in the rotor generator of a steam power plant located in Lontar, Banten Province, Indonesia. The steam power plant has 3 x 315 MV capacity and uses hydrogen in the cooling system. The issue arising during the operation was caused by heat transfer exceeding the normal level. The grounding of the rotor occurred through rising vibration and temperature, tripping the generator unit. During repairs, the axial spacer was replaced with a new model, where it is longer than the original, adding a bar spacer at a previously unavailable position and creating a cooling track profile. This is a case study on the replacement of the axial spacer model aimed at preventing the expansion of the winding, so as not to touch with each other, through the installation of a longer axial spacer and the addition of the spacer bar, and lastly adding the track profile to the cooling hydrogen gas flow thereby maximizing the cooling process from the end winding rotor generator. Heat transfer is an analysed parameter related to the model change of the axial spacer. The addition of a track cooling gas flow has been able to maximize the heat transfer process, which is simulated in this paper. The performance of the rotor generator increased through several parameters after the replacement of the axial spacer model.

Abstract
Malaysia’s population has been steadily increasing thus resulting in higher demand in residential housing. Modern housing design perceived as neglecting our local traditions, climate and context, cutting ourselves off from our past architectural heritage, which was highly practical with applications of passive design elements. The traditional Malay houses were exceptionally well designed to suit the warm and humid Malaysian climate and for the multifunctional use of space compared to terraced houses. This research aims to compare the energy conservation between traditional Malay house and terraced house from thermal comfort and lighting perspective. It studies on traditional Malay house (TMH) specifically ‘Rumah Bumbung Panjang’ as representative of climate response building. In contrast, the modern terraced house (TH) was represented by modern building that use artificial and mechanical lighting and ventilation to achieve thermal and lighting comfort. This research bases on data collected using a multifunction anemometer that includes illuminance levels, temperature and relative humidity. The data then tabulated and analysed. The research suggested that adaptation of traditional Malay house architectural elements would increase energy efficiency in terraced houses, thus conserved more energy. It also indicated that traditional Malay house could be easily adapted in the design of modern terraced houses and improved to meet the requirements of modern living.
