Abstract

The ordinary least square method (MKT) is a classic method to estimate parameters in regression modelling. The MKT has classical assumption, where these assumptions must be fulfilled. One of the causes of violation of classical assumptions is the presence of outlier observations. Robust regression is an alternative for correcting parameters in data that indicate outliers. In this article, we apply robust regression using estimation-M in data modelling of infant mortality rates that occur in West Java. Based on the mean squared error (MSE) criterion in the estimation-M, it is obtained that the Huber approach has a lower MSE than Tukey Bisquare. The results of estimation using Huber show that only the low number of births has a significant effect on infant mortality in West Java, with an effect of 2.047.

Abstract

In today's digital era, the development of Database Management Systems (DBMS) explores the important role of storing, managing and accessing data efficiently. This research aims to analyze the DBMS development process using MySQL. Initial planning, where business needs and data requirements are identified. The database structure is then designed by considering normalization and relationships between entities. After installing MySQL, a database is created with a predetermined design. Next, the table is implemented by setting the columns, data types, and primary/foreign keys. User access rights are defined to ensure data security, and functions and stored procedures are implemented to facilitate complex data processing. Indexes are added to improve query performance. Backup and recovery management is an important focus in ensuring data continuity. Application integration is carried out by matching the application interface with the database system using the MySQL API or driver. This research presents a systematic guide for DBMS development using MySQL. Overall, using MySQL as a database management system offers flexibility, high performance and reliable security to support business needs in storing and managing data.

Abstract

In this research, a viability test was carried out to obtain information about the ability of shallots to germinate under certain conditions. The use of hot water in Murashige and Skog media is a way to obtain information on certain conditions. The aim of this research is to determine the effect of hot water immersion temperature and water soaking time on the viability of shallot seeds (Allium cepa L.) on Murashige and Skog media. This research was carried out at the Alifa Agricultural Research Center (AARC) Laboratory. This research used a completely randomized factorial design (RAL) with two factors, the first factor was hot water temperature with 3 levels, namely: S0 = 27 ? C (control), S1 = 45 ? C, S2 = 60 ? C. The second factor is the length of immersion with 3 levels, namely: L0 = 3 seconds (control), L1 = 10 minutes, L2 = 15 minutes, a combination of 9 treatments which were repeated 3 times to obtain 27 experimental units. The number of samples in each experiment was 3, so the total sample was 81. The parameters measured were the percentage of plumule emergence (%), the percentage of radicle emergence (%), the percentage of live explants (%), the percentage of explants contaminated with bacteria (%), the percentage of explants contaminated with fungi (%), the number of shoots (plants), the height of plants (cm), number of leaves and number of roots. The results showed that the observed heat treatment had no significant effect on the observed parameters of the percentage of explants contaminated with bacteria, the percentage of explants contaminated with fungi, and the number of roots. In the long soaking treatment, it was observed that it had a significant effect on the percentage of live explants. The interaction of temperature treatment and soaking time had a significant effect on the percentage of live explants.

Abstract

This study aims to test the performance of an Expert Advisor (EA) based on the Relative Strength Index (RSI), Moving Average (MA), and lot optimization on 10 popular forex pairs using a swap-free account. The EA is designed to operate on the MetaTrader 5 platform, utilizing historical data from 2021 to 2024. The study employs a backtesting method to assess EA effectiveness across various market conditions. Results indicate that the EA performs best on lower volatility pairs, such as USDCAD and GBPUSD, showing positive profitability and controlled risk ratios. However, suboptimal performance is observed on high-volatile pairs such as GBPJPY and EURJPY. These findings highlight the importance of tailoring EA strategies to pair volatility characteristics to enhance profitability and risk management.
