This study aims to analyze the quality of service in the Culinary Arts Practical Laboratory at SMK Ibu Pertiwi 1 using the Service Quality (Servqual) method. Service quality is an important element in supporting the success of the education process, especially in the Culinary Arts expertise program that requires laboratory facilities as a means of practical learning. The Servqual method is used to evaluate five main dimensions, namely tangibles, reliability, responsiveness, assurance, and empathy.This study was conducted by collecting data through questionnaires distributed to students as users of laboratory services. Data analysis used a comparison between students' expectations of ideal service quality and their perceptions of the services received. The results of the study showed a gap in several dimensions of service quality, especially in the tangibles dimension which includes the completeness and condition of laboratory facilities. In addition, the responsiveness and reliability dimensions are also of concern because students feel that the response to complaints and service consistency are not optimal.From the results of the study, it can be concluded that the quality of laboratory services needs to be improved to meet student expectations. Recommendations for improvement include improving physical facilities, training for laboratory staff to improve responsiveness and reliability, and strengthening security assurance in the practical learning process. This study contributes to school management in creating a more effective and quality learning environment.

The rapid development of science and technology has driven increasingly intense global competition, demanding educational institutions to play an active role in developing human resources (HR). Higher education serves as a platform to enhance students' competitiveness, not only through academic education but also through student organizations such as the Student Executive Board (BEM). This organization provides opportunities for students to develop social skills, leadership, and other soft skills that are highly essential in the professional world. STMIK Widuri, as one of the higher education institutions in Indonesia, integrates academic education with students' personal development through organizations like BEM. This study aims to evaluate the level of satisfaction among the academic community regarding activities organized by the BEM of STMIK Widuri during the 2023–2025 period using the Service Quality (SERVQUAL) approach. This method measures service quality based on five key dimensions: reliability, responsiveness, assurance, empathy, and tangible aspects. Data were collected through interviews, observations, questionnaires, and literature reviews, with a total of 51 respondents comprising students, lecturers, and staff. The results of the study indicate that all data are valid and reliable based on the Cronbach Alpha test, with values exceeding 0.6. Analysis using SPSS software shows a gap between respondents' perceptions and expectations of the services provided by BEM. These findings are expected to provide insights for the BEM of STMIK Widuri to improve service quality and design programs that better align with the needs of the academic community. Thus, BEM's role as a facilitator of student potential development can be further optimized, supporting the achievement of STMIK Widuri's vision as a globally competitive educational institution.

The selection of the best students in schools is essential to recognize both academic and non-academic achievements and to motivate other students to improve their skills. SMP Negeri 16 Jakarta requires an objective decision support system to select the best students based on predefined criteria. This study aims to design and implement a decision support system using the Simple Additive Weighting (SAW) method to facilitate the selection of the best students at SMPN 16 Jakarta. The SAW method is chosen due to its capability to accommodate multiple criteria through weighting and ranking for each alternative. The research process involves observation, interviews, and documentation, which are then used to determine primary criteria such as academic achievement, social skills, and participation in school activities. The findings show that the application of the SAW method enables a more accurate and objective selection of the best students by ranking based on the final score of each criterion. This system is expected to assist SMPN 16 Jakarta in making more structured decisions and supporting educational quality improvement.

An expert system is artificial intelligence that imitates the ability of an expert to solve problems in a certain domain. Utilizing a knowledge base and specified rules, the expert system provides advice or decisions that approach human expertise in this specific field, especially regarding cholesterol disease for teenagers, cholesterol disease can cause death in a person so it needs initial treatment as a diagnosis. In this regard, an expert system application is needed to diagnose cholesterol disease for users which supports the diagnosis process using the certainty factor method, based on the certainty factor which has a concept based on symptoms and diagnosis from the weight of an expert's value and the user's value, then calculated using the certainty factor formula, The final result is the creation of an expert system application for diagnosing cholesterol disease using a website-based certainty factor method.

The Information System is a collection of systems in its aspect consisting of software, hardware and brainware in a structured manner with performance in a gradual and interconnected process so as to create a specific product that is needed by the user, but related to ordering curtain products for customers in companies generally have a process of ordering curtain products to customers from the company, but along with the development of a website-based information system that can make it easier for companies to carry out performance in the process of ordering curtain products for customers, then from ordering curtain products to customers there are several problem factors that influence it, namely, the difficulty of ordering products curtains because they still use paper for recording so that it takes quite a long time and customers cannot know the availability of curtain products to re-stock again, the purpose of which is a reference for research is to design an information system for ordering curtain products for customers so that they can be fast and flexible, Based on these 2 problems, the solution is to create an information system according to the needs of ordering curtain products that will be used by the company in serving the ordering process, then from this it will create the results of an information system for ordering curtain products for companies for website-based customers, before being used by users from development that makes the application perform testing with blackbox as an evaluation stage of the information system that has been made based on features, blackbox has concepts such as verifying the features used if appropriate will obtain valid results whereas if not appropriate then retesting the information system.
