Identifying Insect Pests of Glutinous Corn Plants (Zea mays ceratina Kulesh) with Various Organic Fertilizer Treatments
Get PDFGlutinous corn (Zea mays ceratina Kulesh) is a variety of corn that holds significant economic value. However, the productivity of this plant is frequently compromised by insect pest infestations. This study aims to investigate the effects of organic fertilizer on the insect pest population and identify the types of insect pests affecting glutinous corn plants. The objectives of this research are to assess the abundance of insect pests in glutinous corn plants under three treatments: (1) no organic fertilizer, (2) liquid organic fertilizer, (3) solid organic fertilizer, and (4) a combination of liquid and solid organic fertilizers. The research methods include field observations, insect sampling, and laboratory analyses for pest identification based on morphological characteristics. This study employed a non-factorial Randomized Block Design (RBD) with four treatments and six replications, resulting in 24 experimental plots. The results indicated that insect pests were highest in the treatment that did not utilize organic fertilizer. The types of insect pests found on glutinous corn plants belong to the orders Orthoptera, Coleoptera, Hemiptera, and Lepidoptera and were observed from the vegetative to the generative periods. Applying solid organic fertilizer from chicken manure proved the most effective treatment for enhancing corn production, yielding a production weight of 1.36 kg per plot, equivalent to 9.07 tons per hectare

Database Consistency Improvement In Job Offering System Using Normalization Method
Get PDFThe role of information systems in modern life today is very important, especially in a company to make strategic decisions or actions. Information systems must be free from data anomalies. Data anomalies can occur due to poor database structure design. This happens in job offering systems that still have data anomalies. This study uses the normalization method to verify the quality of the database in the job offering system. Normalization is a technique that focuses on grouping several attributes into an entity based on certain criteria to achieve normal form. Normalization aims to maintain data consistency and integrity. The job offering information system has two databases to carry out all its functions. The first database is for the needs of processing job offering information system data. The second database is for the needs of processing company organizational structure data. This study has identified both databases of the job offering system. There are 2 violations of the normalization provisions found. Violations occur in the employee and schedule_wwc tables which do not follow the 3NF normalization provisions. Improvements need to be made to the database to improve data consistency in the job offering system. This study has made improvements by modeling data according to the data needs of the job vacancy information system. The modeling produces a conceptual data model (CDM), a logical data model (LDM) and a physical data model (PDM). The modeling results have been reverified using the normalization method and are free from any violations
