Abstract

Telemetry systems have been widely used in industrial machines to continuously monitor movement and data from industrial machinery. However, obstacles occured in areas that have not been reached by cellular or internet signals such as mining areas and oil palm plantations. One machine that requires continuous attention is the Genset engine or power plant. Howevwr, the officers had to be placedon that site or are not effectively. Therefore it is necessary to make remote monitoring and control to determine the condition of the generator, especially the generator temperature, because of the temperature indicator can be known the performance and efficiency of the generator. The information of generator indicates the performance of generator, such as temperature and fuel comsumtion. A monotoring should done remotaly wheneverrural areas are further away from the head master offices. Real time monitoring proposed where able to change and control generator. FM transceiver used to addressing the limitation of protocil communication or rural areas since the GSM signals and internet are not coveraged that areas. Half duplex protocol communication is proposed to manage data exchange between Tx and Rx.

Abstract

Indonesian government set the target for new and renewable energy (NRE) is expected to be 23% in 2025 and 31% in 2050, where in 2017, NRE was only 12,5%. Building a new and renewable energy project is the easy part. Keeping the generator working over time, however, is a complex business that requires money, training and innovative thinking. One of essential parameters that can help in achieving a successful sustainable project is community involvement. If the community feels a strong sense of ownership, they'll see their generator as a critical asset to everyone and take good care of it collectively. Training and educating the community about how to take care of the generator after the project construction has completed becomes important. Considering Indonesia’s geographical location, e-learning might be a potential tool to reduce training and education cost in new and renewable project. This study aims to identify whether e-learning is an effective and efficient method to deliver training material and educate local people which will improve renewable energy project’s sustainability in Indonesia.

Abstract

Drowsiness that felt by the driver will affect the security of someone when driving. It can be seen that many accidents cause death due to drowsiness when driving. Due to the effects of fatigue after some busy activities and the responsibility to keep going home. However, this is not supported by the motorist's awareness of not continuing the journey and resting for a while until the physical condition returns to normal. So to reduce the number of accidents that occurred needed a capable tool of detecting sleepiness through the state's heartbeat using a heartbeat sensor (XD-58C) to the rider who can awaken directly by using vibration motors and buzzer, and if an emergency occurs, namely when the driver crashed, the tool will send point location via SMS to the families, hospitals and police stations using GSM module SIM800L, point locations that are read by an integrated GPS module with microcontroller arduino during an accident that can be used by the driver. Keywords: XD-58C Sensor, Drowsiness Detection System, Emergency Detection, GSM SIM800L, modul GPS

Abstract

Among the sources of electrical energy used in remote areas or mountains are using micro hydro power plants (PLTMH). The problem that arises in PLTMH Curug Muncar is the low power factor (cos ϴ) in the distribution. The power factor measured in users / consumers is an average of 0.7. One of the reasons for this is the varied type and use of loads on consumers, resulting in waste reactive power.               As an alternative solution to these problems is to compensate for electrical power to load changes that are very dynamic. From the reference, it shows that the Static Synchronous Compensator (STATCOM) is the most effective reactive power compensator.               STATCOM is located in the position between the generator and load variation. The reactive power settings by STATCOM occur by comparing the value of the terminal voltage between STATCOM and the system. If the STATCOM voltage is lower than the system, the STATCOM will absorb reactive power from the system. Meanwhile, if the STATCOM voltage is higher than the system, the STATCOM will generate reactive power to the system               STATCOM is able to compensate for reactive power with a very fast time (0.3 seconds) and is able to absorb or provide reactive power to the distribution. STATCOM is able to change cos θ from 0.7 to 0.93. The repaired voltage is close to the given Vrms value. Keywords: PLTMH. STATCOM, Reactive Power

Abstract

Telecommunication Service Provider should deal with illegal players (grey operators) who do not have permission to conduct international voice service. These illegal players perform their activities by passing international incoming traffic using Simbox devices. To identify visual simbox usage is very difficult and less reliable, therefore by using spectrum analyzer and K-Nearest Neighbor (K-NN) method is one way to identify simbox usage. The attributes used in the identification process are Location / Document, Strong Frequency Signal, and by applying K-NN algorithm based on proximity of training data with data testing. The determination of this attribute is based on GSM DCS 1800 MHz uplink frequency measurement in Cilacap and Banyumas area. The identification process was conducted on six frequencies points on 18 data with the largest signal strength as training data. Moreover, the signal strength data testing  by using 32 data gives result 81.25% accuracy. The results of K-NN algorithm calculations can be implemented to identify the use of simbox, hence it can be used as a reference for mobile operators to identify simbox usage in other areas.Telecommunication Service Provider should deal with illegal players (grey operators) who do not have permission to conduct international voice service.

Abstract

Younger babies born with low body weight are increasingly critical and at risk for these babies. To overcome this problem, we need a device of medical equipment that can replace uterine function, whose condition is like that of a baby still in the womb of his mother. Temperature, humidity, oxygen, sound and light levels for the development of the most suitable low birth weight babies. Not only the temperature, humidity and noise factors that must be considered, but also pay attention to other problems that can interfere with baby's health, among others; Factors such as skin that directly contact family members also contribute to disease in infants, because baby's skin is still very sensitive, and has the potential to become infected. Babies with very low birth weight have a very high risk, especially when they feel cold. When a baby experiences heat loss, creating a physiological response that exceeds that of a normal baby, physiological balance will be severely disrupted, this is because the baby needs to expend energy and metabolize oxygen to produce its own heat. The purpose of using an incubator is to create a very stable environment so that the birth of a baby with a low body weight can maintain a constant body temperature. In designing the incubator must pay attention to the condition of the humidity in the chamber, for the sensitivity of the chamber temperature is relatively easier but if the conditions of dry humidity will greatly affect the health of the baby. Ideal moisture loss will cause transepidermal water loss (TEWL) in premature infants. From the results of the Overall System Measurement and Research conducted in RSUP Dr. Sarjito on April 23, 2019. This location was chosen because the place has a temperature, humidity and noise level that is stable enough so that it is suitable for the location of the baby incubator.
