Abstract

Employee performance is essential in determining the company's sustainability, so company leaders must pay attention to employee performance. Many subjective factors determine employee performance, so performance evaluations are sometimes unfair. One of the companies developing in Indonesia is a smartphone sales company, CV Jala Kencana. As the company develops and the number of employees increases, problems arise in assessing employee performance that have yet to be measurable. So that employee performance assessments can be more objective, a decision support system application is needed that can help assess employee performance. The Agile SDLC method is used in designing website-based employee performance assessment applications. Then, for the employee performance assessment feature, the Simple Multi-Attribute Rating Technique (SMART) method is used, and SHA512 encryption is applied to the employee performance assessment database, which cannot be manipulated. This research produces a web-based employee performance assessment application with features to assess employee performance objectively based on predetermined criteria.

Abstract

Respiratory diseases require early diagnosis and continuous monitoring, but existing methods involve risky physical contact. This study proposes a new system that uses FMCW radar and machine learning to monitor breathing without contact. FMCW radar can detect respiratory movements in real-time, while machine learning can classify respiratory waveforms. This study evaluates the system with cross-validation Shuffle Split, K-fold, and Stratified K-fold. The results show that Random Forest has the highest accuracy of 94.6% and Naïve Bayes has the shortest time of 0.055 seconds. Shuffle Split performs best overall. This study shows the feasibility and potential of the system for the detection, response, and tracking of respiratory diseases in emergencies.

Abstract

Pontianak Siamese oranges (Citrus nobilis var. microcarpa) are one of West Kalimantan's leading commodities, which were first developed in the Tebas & Pemangkat area, Sambas Regency. Orange seeds have polyembryony, that is, there is more than one embryo in one seed, originating from a zygotic embryo and a somatic embryo. This research aims to determine the effect and appropriate concentration of adding corn extract and NAA to produce the best growth in Pontianak Siamese orange seed culture. This research used a completely randomized factorial design (CRD) with two factors. The first factor is corn extract (J) with 4 concentration levels, 0% (J0); 7,5% (J1); 10% (J2) and 12,5% ​​(J3). The second factor is NAA (N) with 4 concentration levels 0 M (N0); 10-7M (N1); 5.10-7M (N2) and 10-6M (N3). The data obtained was analyzed descriptively. The research results showed that the treatment of 12,5% ​​corn extract + 10-6M NAA (J3N3) was the best treatment for the time of sprout emergence and the fastest time for shoot emergence, namely 9,33 and 13,33 days. The treatment of 0% corn extract + 10-7M NAA (J0N1) produced the highest number of polyembryony shoots, namely 3,33 shoots. The 0% corn extract + 5.10-7M NAA (J0N2) treatment was the best treatment for the highest number of leaves on shoots from polyembryonic seeds, namely 2,16 pieces. The 7,5% corn extract + 10-6M NAA (J1N3) treatment and the 10% corn extract + 10-7M NAA (J2N1) treatment were the best treatments for the number of roots, namely 6 roots.

Abstract

This research aims to apply the linear regression method as a tool for forecasting aquaculture exchange rates (NTPI) in West Papua province. This research uses Jupyter Notebook as a data processing platform by combining the concepts of data mining and regression analysis. Analysis of fish cultivation data and related factors such as farmer income index, household consumption index, etc. to predict NTPI values. This method can help design policies that support economic growth in the aquaculture sector by optimizing exchange rates. These results show that although predictions provide insight, there are certain limitations when using linear regression models to predict the future. The mean squared error (MSE) is 90.78 so further considerations are needed to improve model accuracy. Nevertheless, this research will provide a basis for the West Papua provincial government to implement more effective measures in the aquaculture sector.
