Analisis Sistem Human Interface (HMI) Pada Kompetensi Programmable Logic Controller (PLC)

This analysis aims to determine the difference between Human Machine Interface (HMI) based learning media and conventional learning media in influencing student competence in operating the Programmable Logic Controller (PLC). The method used was a true experimental design with a posttest-only control group design. The experimental group was given learning treatment assisted by HMI Omron with the CX-Designer software, while the control group was given treatment with conventional learning media. The treatment effect was analyzed by using different test (Mann-Whitney). The results showed that the effect of HMI-based learning media on PLC competence is as follows: (1) 61% competence in the cognitive domain is in the very good category, 50% competence in the affective domain is in the very good category, and 50% competence in the psychomotor domain is in the very good category; and (2) There are competency differences between HMI-based learning media and conventional learning. This is evidenced by the Sig. Count value of 0.000 in the cognitive domain, 0.000 in the affective domain, and 0.001 in the psychomotor domain, which is smaller than the Sig. Of the study of 0.05 after being given treatment

The Incidence and Severity of Downy Mildew Disease on Local Madurese Maize Crops in Sumenep District, East Java, Indonesia

In Madura island, corn is the main commodity that is widely planted with an area of 301,725 ha or about 30% of the area of maize in East Java. Madura Island has local cultivars, such as: Tambin, Talango, Guluk-guluk, Manding, and Kretek. Efforts to increase production are continuously being made, starting from improving varieties until managing plant pests. One of the main diseases in maize is downy mildew. However, information about the incidence, incidence, severity, and species that cause downy mildew in local cultivars has not been reported. So, this study aims to identify the causes of downy mildew in local cultivars of Madura and disease severity in the field. The research method is a survey on local maize centers. Sampling was done by using the diagonal sampling method. Each plant sample was observed for symptoms of disease and scoring to calculate the value of disease severity. Fungi identification was carried out by microscopic observation of the fungus. The results showed that the cause of downy mildew in Madura local maize in Sumenep Regency was P. maydis. The highest incidence, disease severity, and AUDPC value after 4 MST were found in Guluk-guluk cultivars in Padangdangan Village, but had the lowest disease progression rate values. Meanwhile, the highest rate of disease progression was found in the Manding cultivar in Mandala Village. Based on the resistance category, Talango cultivar had the best resistance when compared to other cultiva

Analysis of Brand Experience and Brand Satisfaction with Brand Loyalty Through Brand Trust as A Variable Mediation

This research examines the influence of brand experience and brand satisfaction of brand loyalty with brand trust as intervening variable. The samples used in this study were 130 respondents who were Honda motorcycle customers in Medan city. Nonprobability sampling Technique by purposive sampling method is used as a sampling technique. The analysis method is Structural Equation Modeling (SEM) using the AMOS-20 (Analysis of Moment Structure) device. It was found that brand experience and brand Trust have significant effect on brand trust and brand loyalty. Brand Trust is a significant effect on brand loyalty. Brand Trust is a partial mediation the influence of brand experience and brand trust of brand loyalty
