Abstract

Predictive Maintenance (PdM) at the PLN Power Plant is a periodic monitoring of equipment activities before the equipment is damaged in more severe conditions. According to an expert or PdM owner that maintenance analysis is not appropriate and efficiency has an impact on maintenance costs that are not small. In real conditions, the PdM owner analyzes equipment damage based on previous cases of damage equipment. Then we need a computer-based intelligent system that can help detect damage to equipment.Based on the Literature Review that has been done, Case-Based Reasoning can solve new problems using answers or experiences from old problems such as imitating human abilities. Case-Based Reasoning Process there is the most important step, which is to find the highest similarity value or the level of similarity between new cases and old cases by adapting solutions from old cases that have occurred (Sankar, 2004). In this study the process of similarity or approach using Nearest Neighbor.Testing on the system uses 20 test data and the measurement of system performance uses confusion matrix. Evaluation of testing using confusion matrix can be seen how accurately the system can classify data correctly that is equal to 97.98%. Then the precision value of 95% represents the number of positive categorized data that is correctly divided by the total data classified as positive. Furthermore, the test results of the equipment damage detection test data at the PLN plant with a threshold value of 0.75 using the nearest neighbor, the system has a performance with a 95% sensitivity level.

Abstract

Telkom Lampung Vocational School has four competency skills that you can choose from. These four skill competencies are related to one another. The major related to the internet of things is TKJ, so this class was invited as a training participant. IoT training is indeed one of the requirements requested by Telkom Vocational School. This request is because the Internet of Things (IoT) is a technology that is being discussed lately. With this technology, every device that we use can later be connected to the internet. This training received good appreciation from the teacher and also the students who participated in this activity. The students were very enthusiastic in participating in the internet of things training because it added to their knowledge and skills. Hopefully the implementation of this training will add enthusiasm for students to continue learning and be able to continue to the higher education level.

Abstract

The need to access the latest information in the form of images, text, videos, animations, and more from various sources through websites using smartphones, tablets, laptops, and PCs connected to the internet is being done by everyone in today's era. Therefore, the need for human resources to create or develop web-based technology in institutions is highly required. Web-based technology is created to help solve problems in these institutions. In addition to supporting web-based technology, the acceleration of mastering software development technology is also carried out, including the development of frameworks. One of the latest and widely used web-based system frameworks today is Laravel. Knowledge of web programming needs to be conveyed early on, such as in vocational high schools for majors that lead to producing software engineering professionals. SMK Telkom Lampung is one of the vocational high schools that has an RPL major. Therefore, it is necessary to carry out Community Service by conducting web programming training using the Laravel framework for students in the Software Engineering major at SMK Telkom Lampung, who are still learning using native web pages. The training was held for 1 day on Friday, February 24th, 2023, in the Computer Laboratory of SMK Telkom Lampung and was attended by 19 RPL major students. Some of the software that supported the training were xampp, composer, and Laravel 8.*. The evaluation results of the training showed that 100% of the participants were able to understand, interested, and motivated by the material presented.

Abstract

Villages have less development than cities because villages have bigger problems such as higher poverty rates, lower health, lower human resources, facilities and infrastructure that are more difficult to reach than cities. Therefore we need the concept of sustainable village development. In sustainable development, the aspect of development is not only aimed at present society but also society in the future. Before making the concept of sustainable village development, so that village development in a city/regency/district area is conceptualized evenly, decision support is needed to identify underdeveloped villages. Some indicators villages or underdeveloped regions mostly related to the survey of Potensi Desa activities by BPS from 1980 to 2014 continually participated. Related to that conditions, criteria obtained underdeveloped villages by DPU and indicator data PODES by BPS, it can be applied on Decision Making System. In this research selected case studies are census data from Potensi Desa by BPS in Magetan. This system uses SMARTER (Simple Multi-Attribute Rating Technique Exploiting Ranks) methods as the calculation of the weights to the criteria and ORESTE methods used for the rankings of underdeveloped villages. In this system SMARTER methods using a weighting formula Rank Order Centroid (ROC) that is proportional weighting which reflects the distance and the priority of each criteria appropriately. Furthermore, the ranking process using Oreste methods by three main stages that is Projection Matrix position, Ranking of projections and Agegration of Global Ranking. Testing of this system, which one is changing the parameters of Oreste (α value) and obtained compatibility reach 91.06% of accuracy to the experts data of underdeveloped villages from the BPS Magetan by the number 100% alternative data with value 0:01 of alpha

Abstract

Photography service users often face difficulties in accessing effective and efficient photography services through digital platforms. This study aims to develop a web-based photography information system using the Agile method, which allows for rapid adaptation to user needs and market changes through continuous iterations. The development results indicate that the system can effectively provide key features such as account registration, login, dashboard, photographer services, and photography equipment rental. Functional and non-functional testing ensures that the system operates well and meets user needs. However, there are challenges in optimizing security features and response times that need to be addressed in the next iteration. The system has been successfully developed and is capable of providing better services to users, although further improvements are needed in some technical aspects.
