Abstract

Electricity monitoring is making to determine the quality of electricity used. Currently, electricity monitoring is still done manually together with it requires a system that can measure the electrical parameters automatically. Therefore, an electrical monitoring system is designed for a three-phase system based on a wireless sensor network (WSN) using LoRa communication. The system consists of a transmitter node as a measured voltage, current, frequency, power factor, and active power using the PZEM-004T module. The receiver node is a gateway that receives data from the transmitter node used LoRa transmission and then forwards the data to be stored in a database using the internet network. The receiver node is equipped with backup data when the node receiver cannot be connected to the internet network. Finally, web monitoring is designed to make it easier for users to access electricity monitoring data online. Web monitoring will display data onto voltage, current, frequency, power factor in a single-phase system and active power in the form of the three-phase system into tables and graphs.

Abstract

This study aims to identify microservices in sistem informasi dosen (SIMDOSEN) of udayana university using Domain Driven Design analysis. SIMDOSEN was developed with a monolithic architecture and has several modules including lecturer data management module, lecturer history, management of tridharma perguruan tinggi activities, lecturer performance targets, etc. Dynamic policy changes cause the system to be difficult to adapt to accommodate needs and lack of documentation cause different interpretations of system function between programmers. With microservices, the system will be split into several services using a RESTful API which is documented using OpenAPI Specifications so that it is hoped that the development of SIMDOSEN will be more adaptive to changes in system requirements and reduce misunderstanding between programmers in the future.

Abstract

This paper designed a medical image compression scheme using DWT with mother wavelet Coiflet and Symlet. Thresholding and quantization process are the key to lossy compression in this scheme, and the outputs will be coded with Huffman or Arithmetic coding. There are four different codec combinations namely: Coiflet-Huffman, Coiflet-Arithmetic, Symlet-Huffman, Symlet-Arithmetic. Compression performance of each codec will be analyzed based on PSNR and compression ratio. The compression testing used 3 grayscale medical images with dimension of 160x160 pixels. The most optimal PSNR dan rate are produced by Symlet-Aritchmetic codec with recommendation threshold value less than 12. Threshold value above 12 causes PSNR of the reconstruction image will be below the minimum PSNR stardard for digital image, which is of 30dB.

Abstract

Abstract—Decision Support Systems help decision making to solve very unstructured problems and complex. Every decision-making process always results in one final choice. In the application of decision support systems often use the Analytical Hierarchy Process (AHP) method. AHP can solve complex problems where many criteria are taken. In addition to the application of DSS, the authors also analyze the effect of implementing Decision Support Systems in an institution using simple linear regression. Simple linear regression is used to determine the effect of independent variables on the dependent variable. From several research reviews in Indonesia, many have applied the Analytical Hierarchy Process (AHP) method to assist in the decision support process. These institutions / organizations are active, in the fields of Academic, Private, Hospital, Tourism, and Government. This study found the results of the evaluation of the desktop-based AHP system development to be the most dominant with a figure of 58% where in government projects the largest was 48%. Keywords: Decision Support Systems, Analytical Hierarchy Process, AHP, Information System, Simple linear regression.

Abstract

Australia is one of the countries with the highest solar PV capacity in the world. The capacity of solar PV installed in Australia has reached 16,319 MW and 600 W per capita at the end of 2019, making Australia the country with the highest per-capita capacity in the world. The Australian Government has established policies, regulations, and budgets as commitments to support the achievement of the solar PV capacity. This paper reviews and analyzes policies, regulations, and funds in Australia from federal to state levels on the side of solar PV development. Analysis showed that policies and regulations supported by the suitability of the government budget have a consequential effect on increasing the capacity of solar PV to implement and realize renewable energy targets in Australia. Several policies aforementioned as Feed-in Tariff, RET, NSSP, and budgets that focus on R&D have a significant impact on increasing the capacity of solar PV installed. Thus, realistic targets that are phased in, structured policy and regulatory support, budget compliance, and continuous education to the public are essential aspects that could be adopted in Indonesia to accelerate the realization of the national solar PV capacity target.
