Abstract

Dye-sensitized solar cell (DSSC) is one of the potential candidates for the next generation solar cells. One of the most attractive features of the DSSC is the low production costs. The utilization of natural dyes is a new area for investigation due to their unique capability to absorb photons from natural sunlight or artificial light and convert it into electric current. The purpose of this study is to determine the potential of natural dye from red dragon fruit waste as a dye sensitizer. Red dragon fruit peel is initially extracted using methanol and the solution absorption spectra then is characterized using UV-Vis spectrophotometer. The absorption spectra is measured within a wavelength range of 400-800 nm. The characterization results show that the maximum absorption spectrum is at a wavelength of 446 nm. The natural dye solution then is used to immerse Fluorine Tin Oxide (FTO) coated with titanium dioxide (TiO2). The glass FTO is immersed in the dye solution for 24 hours. DSSC then is prepared by sandwiching the working electrode and counter electrode. An electrolyte solution is used to fill the interface between the two electrodes. The current and voltage (I-V) characteristics of DSSC is finally measured using amperemeter and voltmeter. The results indicated that the natural dye from the peel of red dragon fruit has potential as a dye sensitizer. Further research is still required to improve the performance of the DSSC.

Abstract

Indonesia plans to build solar PV plants to reach 6500 MW capacity by 2025. One of the solar PV applications is systems with battery storage systems. In this system, the battery is an important component of the solar PV system as it stores the energy for use when the sun is unavailable. This article reviews the status of batteries in Indonesia to support the proliferation of solar PV applications. The objective is to compile a battery database for solar PV applications. The database provides insight into technology and the availability of batteries. The database consists of 361 batteries of various technologies such as FLA, VRLA, VRLA gel, VRLA AGM, and Lithium-ion. The most widely available is the VRLA gel. In terms of voltage, batteries are available at 2 to 12 volts and with capacity from 1 to 3000 Ah. The availability of batteries shows that this field is ready to support the development of solar PV with energy storage although the field of battery recycling or its waste management requires more attention.

Abstract

Dewa Ruci intersection is one point of traffic congestion point in Bali. Dewa Ruci is a major intersection that connects the city of Denpasar, Kuta, Jimbaran, and Nusa Dua. In addressing traffic congestion, built underpass so that traffic becomes smooth when passing through the intersection Dewa Ruci. Part of the Dewa Ruci intersection is below the ground level, so risks of flooding. The source of water that potentially fills the underpass is groundwater seepage and rainfall. The flood protection of the underpass is capable of storing 1344 m3 water and with the pumping system. In this research, the maintenance, operation, and management model of the flood protection system is developed that includes the development of organizational structures and standard operating procedures to ensure that the Dewa Ruci flood protection system works well sustainably.

Abstract

Energy conditions in Indonesia are not balanced so there is an overlap between energy demand and availability. Energy demand will continue to increase with population and industry growth, but the availability of energy will continue to decrease. Uncontrolled energy consumption will certainly increase damage to the environment which in turn worsens global warming. Energy management is a best practice so that the use of energy is well managed. Technological developments can also support energy management by utilizing IoT technology. This study conducted a systematic literature review related to the application of IoT in energy management systems. The results of the literature review conducted are that IoT which was built for energy management consists of several components, such as microcontrollers, sensors, modules, communication protocols, and cloud-based systems. Microcontrollers often used in building IoT systems are Arduino and NodeMCU. The sensor is varies depending on the measurement requirements, usually using the current sensor and voltage sensor.

Abstract

Abstract— An induction motors (IM) in many industries is used because it has several advantages, such as a very simple and strong construction, the price is relatively cheap, has good efficiency, power factor is quite good, and maintenance is easier. Besides the advantages of induction motors also have disadvantages, one disadvantage of induction motors is not being able to maintain a constant speed when there is a change in load. If the load changes, the speed of the induction motor will decrease. One method of regulating the speed of an induction motor presented in this study is the regulation of an induction motor using a carrier based PWM (CBPWM) inverter with the field oriented control (FOC) technique. The estimation of rotor rotation, torque and flux is done by carrier- based PWM technique which is given input voltage and stator current. To achieve the desired flux and torque, estimation is used as feedback in the control system. In this study, it will be simulated the induction motor speed regulation with a carrier base-based inverter using Matlab. The results obtained through simulation show the length of time to reach the reference speed for speeds of 1500 rpm and 1450 rpm is around 0.45 seconds. And THD average 2,675%.

Abstract

Companies are often faced with a number of data and information in the form of unstructured texts. The unstructured data set can be processed / extracted so that it can benefit the company in the decision making process or strategy that must be carried out by the company. Text Mining is one solution to overcome these problems. Text Mining can be defined as the process of retrieving information sourced from several documents. One of the most commonly used text mining tools is Apache UIMA. This study aims to systematically study literature on the implementation of text mining and Apache UIMA by using several related databases, including reviewing text mining, Apache UIMA, and reviewing journal of text mining and Apache UIMA. These journals are reduced using certain criteria. The results obtained are the 20 journals that discuss the implementation of text mining and Apache UIMA. Based on the analysis of these journals, it can be concluded that the application of Text Mining is more widely used in the field of Classification with the method often used is Naive Bayes Classifiers. The average accuracy of the method reaches more than 85%, which means the method is very effective for classification. Specifically, Apache UIMA is more widely implemented in the Information Extraction and NLP fields. The main component of Apache UIMA that is often used is the Annotator Engine and is very effectively implemented for information extraction.
