Abstract

This research presents a low-cost sensor for measuring liquid levels using plastic optical fibers (POF). The sensor reduces the scattering-based optical losses in the fiber, which increase linearly with the liquid height. A U-bent fiber probe and photodetector are used to detect the change in optical intensity. The U-bent probe serves as a test probe for measuring the liquid level. The voltage response difference of the photodetector provides liquid level measurement. This study demonstrates the sensor's responsiveness to liquid level fluctuations above 55 cm at varying temperatures. Sensitivity levels of 1.4 and 3.3 mV/mm were achieved for water level fluctuations below and above 45 cm, respectively. Furthermore, the sensor demonstrated consistently stable responsiveness over multiple cycles.

Abstract

The use of capacitors in electrical systems is widely known for their function to improve power factor and voltage profile while minimizing power losses. It results from the reactive power correction provided by capacitors within the system. It is believed that proper placement and size of capacitors can enhance the electricity quality in power systems. Therefore, numerous methods have been developed regarding the allocation and sizing of capacitors. In this research, a meta-heuristic method, Particle Swarm Optimization (PSO) is applied to find the optimal allocation and sizing of capacitors in order to reduce losses. The method has also been improved by modifying the value of inertia weight to optimize the algorithm's performance in finding the solution. The method is tested on an IEEE 34 bus radial distribution system to observe its performance and effectiveness in identifying the solution. The power loss in the distribution system plays the most important role in the economic operation of the power system. It will be used as a fitness function for each particle in the algorithm. The obtained test results include the size of the capacitor and the optimal placement of the capacitor installation.

Abstract

The majority of people in Kuta Dame Village work as farmers. Several outreaches have been carried out to develop the agricultural sector in Kuta Dame village. However, some of the extension services rarely touched on effective technology to support agriculture in Kuta Dame village. One of the technologies that need to be developed by the Kuta Dame village farmer group in supporting agriculture is an automatic sprayer. This development is necessary because most farmers are still using the carrying type sprayer with a manual pump (diaphragm pump). The sprayer's diaphragm pump pressure produces a relatively low spray pressure, especially when the operator is tired of moving the pump lever. As a result, the spraying performance is not perfect, making the spray grains not smooth and not reaching the leaf surface evenly. A community service program was implemented to implement automatic sprayers for farmers in Kuta Dame village. This community service program aims to carry out the planning process and use of an electric sprayer appropriately to increase spraying fertilizers and pesticides on crops. Implementing this community service activity starts from planning activities, implementing academic counseling, implementing the practice, handing over an electric sprayer, monitoring, and satisfaction analysis.

Abstract

The digital village is a government program that aims to minimize the information gap in rural areas through the use of information and communication technology, and is mandated by Law No. 6/2014. There are four important aspects of a digital village: village governance, economy and food security, village community empowerment, and support facilities. Sibagindar Village, Pagindar Subdistrict, Pakpak Bharat Regency, North Sumatra, is a village that is still an independent, underdeveloped and non-digital village. The village has only one aspect (supporting equipment aspect) of the four aspects that support a digital village. To accommodate the other three aspects so that they are integrated with each other, a platform is needed that can unite them. The information system website can be an integration platform for all aspects that will be digitized later. In addition, the information system website is also a digital gateway to Sibagindar Village. Thus, this activity focuses on the development of an information system website. The stages for the realization of the program include identification of conditions, collection of user requirements, system design, system development, and support for the management of the information system website. The appearance of the website is appropriate and very much in accordance with the results of user requirements gathering. Accessibility of the website is very easy for any device. As much as 83% of the village government and the village community recognized that the presence of the Sibagindar Village Information System website is very useful and motivated to disseminate it.

Abstract

Indonesia is a renowned tourist destination worldwide. However, the COVID-19 pandemic has resulted in a decrease in both foreign and domestic tourist visits. Therefore, this research aims to develop a Telegram-based ChatBot application to increase post-pandemic tourist visits. The ChatBot is designed to make it easier for tourists to obtain information related to transportation and accommodation at tourist attractions. The ChatBot is built using the Knuth-Morris-Pratt (KMP) algorithm and web scraping method. The ChatBot's response to the keyword matching is then presented to tourists. To measure travelers' perceptions of ChatBot, the System Usability Scale (SUS) was used. SUS is a questionnaire consisting of 10 questions that were answered by 20 anonymous users. Based on the calculations, the average SUS score is 71, which indicates that the developed ChatBot is in the good category and suitable for use. Using this ChatBot will make it easier for tourists to obtain tourism information in Indonesia. With its ability to retrieve relevant information related to transportation and accommodation at tourist attractions, the ChatBot can serve as a useful tool to increase post-pandemic tourist visits.

Abstract

The distribution system is a part of the power system that distributes electrical energy from the transmission network to medium and low voltage consumers, such as households, industrial consumers, and other facilities. Network reconfiguration is the process of restructuring and configuring the network by opening and closing switches to obtain the most optimal network configuration. In this study, the determination of switch opening and closing uses the binary particle swarm optimization (BPSO) algorithm, whose basic principle in finding optimal values is based on the social behavior of birds flocking or fish swimming together.. To measure voltage stability, this research presents the Voltage Stability Index (VSI), improving voltage stability using network reconfiguration with the BPSO algorithm. In this study, the VSI value will be compared with other algorithms, including the PSO algorithm from previous research, the Cuckoo Search Algorithm (CSA), the Harmony Search Algorithm (HSA), and the Modified Whale Optimization Algorithm (MWOA). The simulation results show that the BPSO algorithm can reduce power loss from an initial value of 202.7 kW to 139.3 kW, a decrease of 31.28%. Compared to other algorithms, BPSO has the best percentage reduction in power loss. The simulation results also show that the VSI value improved from an initial value of 0.2112 to 0.1520, an increase of 28%. In improving the VSI value in the IEEE 33 bus distribution system, the BPSO algorithm became the best algorithm for enhancing the VSI value.

Abstract

Augmented Reality (AR) can be utilized in various fields, one of which can be used as building information in an educational institution. The purpose of this research is to develop android-based media for building information using Augmented Reality technology with a marker-based tracking method. In developing this media, the MDLC method is used, and Unity with the Vuforia SDK is used. This research produces a building information media application, Augmented Reality technology to display information about rooms in a building that are suitable for use. This media makes it easier for users to recognize the function and location of rooms interactively by simply scanning markers. Thus, this technology provides a new and interesting experience while supporting the digitalization of information services in educational institutions.
