Technological advancements have brought significant transformations across various fields, including the application of machine learning in recommendation and classification systems. Machine learning leverages data processing, utilizes algorithms, and efficiently identifies patterns to produce accurate recommendations and predictions. This study aims to review machine learning-based recommendation system approaches, analyze model performance, and compare the algorithms used. A literature review was conducted by examining journals published in the past five years, focusing on algorithm implementation. The findings indicate that the Naïve Bayes algorithm delivers the best performance, achieving an accuracy of up to 97%. This algorithm is particularly well-suited for processing small to medium-sized datasets with high efficiency. The research provides comprehensive insights into the performance and limitations of various algorithms, serving as a valuable guide for future developments in the field.

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 Betek area, Krucil District, Probolinggo Regency is at the foot of Mount Argopuro with deep groundwater conditions, so water in the ground is difficult to obtain. Currently, the need for clean water in Betek Village relies on spring sources around the area with a network simply built by the community. Unstable water source discharge is felt to be insufficient to meet community needs, especially during the dry season. So a study of underground water was carried out by approaching the electromagnetic field in the study area. One of the earth electromagnetic methods used is the magnetotelleuric method in the form of Audimomagnetotelleuric (ADMT) technology which can be used to determine the groundwater potential at the study location, where later the groundwater potential can be used to meet the community's water needs. The results of the ADMT track analysis on location show the continuity of groundwater potential on this path. Furthermore, an analysis of the ADMT path in the location B section shows the continuity of groundwater potential on the two tracks. At a depth of less than 40 meters, it is almost the same, while at a depth of more than 40 meters, it shows a different continuity. At a depth of less than 50 meters, it is almost the same, while at a depth of more than 60 meters, it shows a different continuity. If we look at the continuity of groundwater potential shown from ADMT-1 and ADMT-2, it shows that groundwater potential is dominant at 30 to 50 meters. So, from these two results, the selection of groundwater potential at ADMT-2 is 45 meters.

Instant Noodle Consumption Education Among University Students is a program aimed at raising awareness of the dangers of excessive instant noodle consumption and the importance of a balanced diet. A situational analysis using a questionnaire based on the Health Belief Model (HBM) provided foundational information on students' perceptions of instant noodles, serving as the basis for developing educational media. Next, a combination of poster and educational video media was used to encourage students to limit their instant noodle consumption. Educational content was shared through the social media platform Instagram to reach a larger student audience, leveraging this platform's capacity for rapid and widespread information dissemination. The results showed an increase in students' awareness about balanced nutrition and the health impacts of instant noodles. Ongoing education is expected to help foster healthier eating habits among students.

This research is motivated by the large number of customers who are interested in using pawn products (rahn), this is because people's needs continue to increase for additional business capital, while the funds they have are limited. However, with increasing community needs, pawnshops themselves are not providing optimal services to customers. However, due to the lack of service received by customers, they still choose Rahn products. So, this research aims to find out the factors that influence customer decisions in picking up Rahn products at the Solok City Branch Sharia Pawnshop and to find out the most dominant factors that influence customer decisions in picking up Rahn products at the Solok City Branch Sharia Pawnshop. This research is quantitative research. The data collection tool uses a questionnaire. The population of this research is all customers who use rahn at the Solok branch of the sharia pawnshop in 2024, totaling 18,033 respondents with a sample of 100 respondents. The data analysis technique in this research uses research instrument tests, prerequisite tests and factor analysis tests with the help of SPSS. Based on the results of research that has been carried out, the results show that there are four factors that influence customers' decisions in purchasing rahn products, namely promotional factors, price factors, sharia aspect factors and location factors. Then the most dominant factor of the four factors that influence customers' decisions in taking Rahn products is the price factor.

Tea plantations are an important sector in Indonesia's agricultural industry that contributes significantly to the country's economy. The success of tea cultivation is highly dependent on the quality of the seedlings, making data collection and management of tea seedlings a crucial element. However, the manual data collection process still used at PTPN4 faces various challenges such as recording errors, data loss, and information delays, which will have an impact on operational efficiency and decision making. This study analyzes the application of a web-based information system for data collection of tea seedlings in PTPN4 plantations, with a focus on the provision or stocking of seedlings. The results show that a web-based system using the waterfall method can improve the efficiency, accuracy, and transparency of data management, while facilitating integration between units in the organization.
Abstrak. Perkebunan teh merupakan sektor penting dalam industri pertanian di indonesia yang memberikan kontribusi signifikan terhadap ekonomi dalam negara. Keberhasilan budidaya tanaman teh sangat bergantung pada kualitas bibit, sehingga pendataan dan pengelolaan bibit teh menjadi elemen krusial.
