Pada android application terdapat informasi kondisi tetes cairan infus yang sudah dikonversi menjadi persentase sisa cairan infus. Hasil eksperimen menunjukkan bahwa prototipe dapat melakukan pengaturan tetes cairan infus per menit sesuai dengan yang diinginkan dan android application dapat menampilkan status dan mengirimkan notifikasi secara akurat. Sebagai kesimpulan dari hasil pengukuran, rata – rata rasio persentase yang dicapai dalam pengujian mencapai 70 % dengan rata – rata error sebesar 1,46 %.

Theoretical Analysis on Interferometric Noise in Bidirectional WDM-PON Transmission Joni Welman Simatupang
Bulletin of Electrical Engineering and Informatics Vol 2, No 1: March 2013
Publisher : Institute of Advanced Engineering and Science

In this paper, theoretical analysis on interferometric noise caused by RB and FR in bidirectional single-fiber single-wavelength transmission over the conventional and long-reach WDM-PON is presented. Conventional WDM-PON takes place in access networks, usually for 20 km transmission distance without node amplification. However, for long-reach WDM-PON which is deployed for 100 km or beyond, optical amplification is an indispensable solution to enhance the power budget and prevent fiber nonlinearities that happening in the high power level. However, optical amplifier in long-reach WDM-PON might cause the RB and FR effects worse compare with their effects in conventional ones. It is due to the nature of re-amplification and re-modulation feedback of backscatter and back-reflection lights which existed at the preceding and following of optical amplifier or remote node gain.

In application of lead-acid batteries for electrical vehicle applications, 48 V of four 12 V batteries in a series configuration are required. However, the battery stack is repeatedly charged and discharged during operation. Hence, differences in charging and discharging speeds may result in a different state-of-charge of battery cells. Without proper protection, it may cause an excessive discharge that leads to premature degradation of the battery. Therefore, a lead-acid battery requires a battery management system to extend the battery lifetime. Following the LTC3305 balancing scheme, the battery balancing circuit with auxiliary storage can employ an imbalance detection algorithm for sequential battery. It happens by comparing the voltage of a battery on the stack and the auxiliary storage. In this paper, we have replaced the function of LTC3305 by a NUCLEO F767ZI microcontroller, so that the balancing process, the battery voltage, the drawn current to or from the auxiliary battery, and the surrounding temperature can be fully monitored. The prototype of a microcontroller-based lead-acid battery balancing system for electrical vehicle application has been fabricated successfully in this work. The batteries voltage monitoring, the auxiliary battery drawn current monitoring, the overcurrent and overheat protection system of this device has also successfully built. Based on the experimental results, the largest voltage imbalance is between battery 1 and battery 2 with a voltage imbalance of 180 mV. This value is still higher than the target of voltage imbalance that must be lower than 12.5 mV. The balancing process for the timer mode operation is faster 1.5 times compared to the continuous mode operation. However, there were no overcurrent or overtemperature occurred during the balancing process for both timer mode and continuous mode operation. Furthermore, refinement of this device prototype is required in the future to improve the performance significantly.

Technological developments that increase the increase in electronic waste (e-waste) significantly. In Indonesia, the method of treating electronic waste by fire is not appropriate to apply, because electronic waste contains metals and will cause dangerous air pollution (for example: lead pollution). Electronic waste processing is different from organic waste that can be processed into fertilizer. Therefore, this condition can be categorized as an important problem, so it requires smart solutions that are fast and precise in processing. Handling this waste can be solved through several methods, namely e-waste banks and art integration. This method prioritizes artistic value, creativity, function, and in-depth knowledge of the waste, so that it can also take advantage of organizations or businesses that will bring profit and be environmentally friendly. This has also received support from the government through a program commonly known as Small and Medium Enterprises (UKM). The components that are usually buried, melted down, and destroyed will be sorted again based on their physicality so that it will facilitate the process of making art.

Government, through the Head of the Communication Bureau, Public Information Services and Cooperation, Ministry of Energy and Mineral Resources, conveyed a plan to build household gas networks in more than 50 districts and cities that aim to balance the mix of fossil energy use in society. The prepaid system is a payment system that allows users to enjoy services after making a payment. It aims to limit the service as needed, while the postpaid system allows its users to use the service indefinitely during the time span given by the service provider. Currently, the household gas network is equipped with postpaid meters, but it does not rule out the possibility of a prepaid system being applied if it is able to provide better convenience and comfort. Based on the research we conducted to determine public response of Cikarang society against the payment system, as much as 55% of the total sample studied preferred to use the postpaid system rather than the prepaid system on the household gas network. However, it is possible to use prepaid payment system for household gas networks (respondent's result is 35%) if the supporting facilities are continuously improved and developed for better service in the future.

The existence of industrial development in Karawang regency, can have a very important impact on the surrounding life, namely good or bad impacts. The good impacts include the creation of many jobs, while the bad impacts include pollution of the surrounding environment such as contamination of water and air quality. Therefore, an accurate, reliable, and real-time water and air quality monitoring system is needed. This can be realized by using wireless sensor network technology online. In fact, there was already 1 location (Base Karawang) for air monitoring, while for water monitoring, there were 3 locations: Qua Warungbambu1, Qua Anggadhita, and Qua Kiarapayung. After the authors conducted research by looking for information related to WSN for monitoring water and air conditions in Karawang, followed by a direct survey, it was found that there was already a real-time and centralized monitoring of water and air quality which could be accessed through the Sensync environmental monitoring platform. Monitoring results data in 4 locations show that air still in a good condition and water quality is light polluted, but no harmful effects for human. With easy access to the air and water conditions in Karawang city, which the data is automatically updated every 10 minutes, making the water and air quality will be more easily to know for everyone.
