Abstract

An expert system for diagnosing developmental disorders in children using the certainty factor method serves as a tool for early detection in children exhibiting unusual behavior for more than three months. Some common disorders in children include autism, oppositional defiant disorder (ODD), mental retardation, and ADHD (Attention Deficit Hyperactivity Disorder). The development of an expert system application for diagnosing developmental disorders in children using the certainty factor method was implemented using PHP and MySQL in the form of a website. Through this application, users can consult with the system as if consulting with an expert to identify the disorder affecting the child based on the symptoms experienced. The application also allows users to view medical records based on the examinations conducted.

Abstract

Red cooking oil is one of the oleofood products derived from CPO whose carotene content is maintained. Carotene is an important compound for the body because it can act as provitamin A. In addition, carotene is also a natural antioxidant for the body. The process of making RPO goes through several stages, one of which is the deodorization process. The deodorization process in making palm cooking oil is different from the deodorization in making RPO. Deodorization in making RPO is no longer intended to reduce ALB but only to improve the aroma of the oil. While deodorization at high temperatures can actually reduce the carotene content in RPO. This study was conducted by varying the deodorization temperature so that the optimal temperature was obtained to eliminate the odor in the oil but still had high carotene and the aroma was still preferred. This study was conducted in the Palm Oil Processing Engineering Laboratory by varying the deodorization temperature, namely 900C, 1200C, and 1500C with a pressure of 36 mmHg.

Abstract

Abstract : This study aims to analyze the response of plants to air pollution in the Binjai City area, which faces increased urbanization and industrial activities. The main focus of this research is the impact of pollutants, such as carbon monoxide (CO), nitrogen dioxide (NO2), and sulfur dioxide (SO2), on the physiology and morphology of plants, including stomatal damage, chlorophyll reduction, and leaf growth. Data were collected through field observations and laboratory analyses of local plant species exposed to urban and suburban environments. The results indicate that air pollution levels negatively correlate with plant health, as observed in the reduction of photosynthesis and biomass production. This study is expected to provide recommendations for environmental conservation and air quality management in urban areas.

Abstract

Scheduling is a division of time so that the work is more efficient and orderly while learning is currently still done manually, so that it has several obstacles faced such as frequent clashes in learning schedules due to lack of accuracy when compiling learning schedules. The process without computerization will feel ineffective if there are many parameters and constraints used, the application of the scheduling information system that will be created later, will further improve performance in making schedules and processing scheduling data. This analysis will run according to plan and objectives, because Elementary School X will use this technology to improve teacher performance in compiling learning schedules. So the result of this analysis is that with the project management analysis for the scheduling information system model, we will be able to predict the needs of the system to be built.

Abstract

Sungai Pagu District has rich natural and cultural tourism potential, but its management has not been optimal due to a lack of community involvement, limited budget, and insufficient human resources in the tourism sector. With the development of Geographic Information System (GIS) technology, it can be utilized in various survey, mapping, and spatial analysis projects. This study aims to analyze the tourism potential and determine the priority for developing tourist attractions in Sungai Pagu District using the Analytical Hierarchy Process (AHP) approach. The criteria used include Tourist Attractions, Facilities, Accessibility, Infrastructure, and Management, with alternatives being natural and cultural tourism. Data were collected through documentation, interviews, questionnaires, and observations, and then analyzed using Microsoft Excel software. The research findings show that there are 3 natural tourist attractions and 5 cultural tourist attractions. Based on the evaluation of 5 criteria, Management received the highest score (58.23%). Among natural tourism, Embung Batu Anyuik is the top priority (67.15%), while among cultural tourism, Menara Songket ranked the highest (40.67%).
