Abstract

Laptops are one of the most widely used computer devices because they have a minimalist and practical design so they can be taken anywhere. Using a laptop for a long period of time sometimes results in various types of damage with a variety of specific symptoms. The availability of technician laptop service locations is not always available within 24 hours. Based on preliminary data, 58% of users do not know the actual location of the damage to their laptop, while 42% of users already know the location of the damage to their laptop, and 48% of users will first find out the cause of the damage on the internet, the other 30% will immediately take it to a service center.. Goal. of this system is to create an Expert System for Diagnosing Laptop Damage and recording the damage history based on a website, making it easier for laptop users to find out where the damage to their laptop is based on the symptoms they experience. System testing was carried out using alpha and beta testing which resulted in an effectiveness test of 85.81, this shows that the system can make it easy for laptop users to find the location of the damage to their laptop based on symptoms.

Abstract

The results of converting solar energy into electrical energy by a photovoltaic system can be utilized for a cooling system. This cooling system is a combination of a photovoltaic system and a thermoelectric cooling system. The electrical energy generated by the photovoltaic system is converted by the thermoelectric cooler into a temperature difference on both of its sides. On the hot side of the thermoelectric cooler, heat is expelled as much as possible so that the cold side can absorb as much heat as possible. The objective of this research is to obtain the cooling performance coefficient and the lowest possible temperature in the cooling space. The research method employed is experimental. Before conducting testing and data collection, a research device is first constructed. The research device used in this study consists of a frame for the solar panel and another frame for the cooler. Solar cells are placed on the upper part of the solar panel frame, while the cooler frame contains a cooling space with walls lined with styrofoam, aluminum, styrofoam, and plywood (from the inside out). This study uses three modules of TEC-12706 thermoelectric type, each equipped with three fans. Data collected include sunlight intensity, wind speed, environmental temperature, air humidity, temperature on the cold side and hot side of the thermoelectric cooler, current and voltage entering the thermoelectric module, and the temperature inside the cooling space. The research results indicate that the coefficient of performance (CoP) for the cooling space is 1.33, and the lowest temperature achieved in the cooling space is 22.2°C.

Abstract

A company complaint system is an important tool for identifying and resolving workplace problems. By implementing transparent, supportive and responsive mechanisms, companies can create a positive work culture and empower employees to report concerns and contribute to overall organizational improvement. However, in the company's complaint system, there are still spam complaints so the process of receiving complaints in a system becomes difficult. The methodology used for research related to spam complaints is TF-IDF Preference Ranking, which involves determining the order of spam and non-spam complaint categories based on similarity values to determine complaint categories based on weighted documents. Blackbox testing of the research results shows that TF-IDF Preference Ranking can filter spam effectively by comparing complaint data with the system's spam dataset. The test results show that 90% of the spam test data can be categorized as spam and 95% of the functional requirements have passed the functional test and are in accordance with user needs.

Abstract

The current trend in the world of education is from traditional education to modern education using new information technology. The author designed a learning media application for children so that they can improve and develop their learning abilities. By making this application, parents can guide them in learning. The aim of this research is to design an application to improve learning abilities using the Waterfall Method. The Waterfall method is a sequential software development approach, with a process that runs sequentially from stage to stage, through the Requirements, Design, Implementation, Verification and Maintenance phases. The results obtained are the creation of an Android-based reading and arithmetic learning media application, where this application consists of several interesting features that can help children aged 4-9 years. The features in this application are packed with simple calculations, reading letters, and number recognition. To measure the application that is built as suitable for use, it is done by testing the application on 20 respondents and each respondent fills out a questionnaire consisting of 10 questions. Based on the results of the data analysis, a score of 78.625 was obtained, which means this application is suitable for use by children both in terms of appearance and content.
