Abstract

A good and really important vaname cultivation is to maintain the quality of shrimp. Shrimp pond water quality includes several parameters including temperature, pH, salinity, oxygen content, and air altitude. The large number of actuators and sensors requires an interface that connects sensors and actuators with humans to facilitate the monitoring process and manual remote control. In this study, a web-based Human Machine Interface (HMI) was built to monitor and control air quality manually remotely. The HMI built in this research uses IoT (Internet of Things) technology so that the process of reading and sending data can be done anywhere, anytime, and through any online device. This website-based HMI was tested using the black box testing method, namely by looking at the experimental results based on the given scenario. The survey results were also given to 5 respondents, 2 of whom considered this website-based HMI to be very good and 3 others considered it normal. From this test, it can be said that the website-based HMI has been successfully implemented

Abstract

Stocks are securities indicating the share of ownership of a company. In stock market, most of traded stocks fluctuate in price at all times and traders take an advantage for taking profit. Traders often use technical analysis to determine the trend of stock price movements. The problem is on how traders take positions (buying/selling stocks) with minimal trading decision so they can maximize profits. Fuzzy rule-based evidential reasoning approach can map the conditions of stock movements. Clustering can help the mapping conducted with a high degree of equality with each other. One of the clustering methods is fuzzy C-means clustering. This method is used to determine the number of membership functions for each attribute. To increase profit/Return of Investment (ROI), verification of output decision is required to analyze stock trends when placing buy or sell. From the results experimented, an ROI of 83.80% profit is obtained.

Abstract

Network activity has increased in every year due to rapid growth of internet users. This phenomenon eventually increases the load server. The high load on server makes server down. The proposed system to handle the issue is using Least Time First-Byte algorithm and multi-agent system in distributed load balancing. The agent collects information resources on the backend servers and communicates with the agents. The Least Time First-Byte algorithm is then combined with the information resources from the agent, called as Least Time First Byte with Multi Agent System (LFB-MAS). The simulation results show that LFB-MAS performs load balance efficiently to all server and provides better performance. The LFB-MAS can process 100% from the 1,800 requests, whereas WLC algorithm is only capable of processing 74.50% from 1,800 requests and LFB without agent is only capable of processing 75.61% from 1,800 requests. The results prove that LFB-MAS can handle high tasks or requests and is reliable.

Abstract

Caregivers of children with special needs experience a high workload, which causes stress and low quality of life. A compassionate love attitude amongst caregivers is needed to improve the quality of parenting. This study aims to develop a compassionate love parenting training program to reduce stress among children with special needs caregivers. The method employed was Pre-experimental Design, with One-group Pre-test-Post-test. The research participants were 40 care­givers identified using the purposive sampling technique. In the pre-test, the stress level of the caregivers was measured using the Parental Stress Scale with 24 items (α = .828). The data were analyzed using the Wilcoxon test to observe the differences between the pre-test and post-test of two dependent samples. The results show that the stress score decreased significantly, with Z = -2.023 and with a significance level of .043 < .05. It is demonstrated that regular training in compassionate love parenting reduced the stress felt by caregivers of children with special needs. The implementation of compassionate love parenting training in special needs therapeutic centers is important, as it is one of the intervention methods that has been proven to reduce the level of stress to optimize the growth of the child.

Abstract

Pemanfaatan cloud computing sebagai mesin komputasi berbasis internet kini menjadi pilihan yang cukup diperhitungkan dalam organisasi. Pengembangan aplikasi dalam organisasi masih dilakukan sesuai permintaan pengguna tanpa melihat kebutuhan pengguna yang lebih luas. Setiap pengguna memiliki obsesi dalam mengembangan sistem dan tidak menggunakan kerangka acuan yang sudah tersedia dalam bentuk roadmap jangka panjang, sehingga muncul sistem informasi yang tidak terintegrasi yang dalam hal fungsionalitas saling tumpang tindih. Perbedaan metode pengembangan aplikasi tersebut menimbulkan masalah lain. Perbedaan model seperti bahasa pemrograman, kerangka kerja dan mesin server menjadi tantangan terserdiri bagi pengelola layanan karena tidak bisa bagian dari sistem yang dikembangkan sebelumnya. Dengan Enterprise Architecture berbasis Cloud SaaS, maka pengembangan roadmap organisasi, tata organisasi, visualisasi proses bisnis dan pengelolaan sistem akan terwujud. Model ini diharapkan mampu menyelesaikan kompleksitas tatakelola teknologi dan sistem Informasi. Dengan implementasi Enterprise Architecture berbasis Cloud SaaS akan mengatasi masalah integrasi sistem.
