The advancement of Autonomous Underwater Vehicles (AUVs) is transforming the way scientists conduct deep-sea exploration and environmental monitoring. AUVs equipped with sophisticated sonar, AI-driven navigation systems, and real-time data transmission capabilities can explore extreme marine environments where human intervention is impossible. This paper reviews state-of-the-art developments in AUV technology, including enhanced battery efficiency, swarm intelligence for coordinated underwater missions, and AI-based anomaly detection for marine biodiversity assessment. Additionally, the study highlights the role of AUVs in disaster response, such as oil spill detection and ocean pollution analysis. By addressing technical challenges such as communication latency, data processing in harsh environments, and energy efficiency, this research aims to contribute to the next generation of AUV applications.

The Mranggen III Health Center is one of the government agencies in the technical implementing unit of the Demak District health office. Patient registration services and administrative payments at the Mranggen III Health Center are still conventional, causing long queues. In addition, the process of processing data to become information cannot be accessed directly by the leadership because there are no computerized and multi-user or client-server applications. Based on these problems, a Puskesmas administration information system design was made that could suit the needs. Making an information system using the programming language Microsoft Visual Basic 6.0 and SQL Server 2000 as a multiuser-based database. With the design of the development of an administrative information system for the Mranggen III Health Center, it is hoped that it will be able to handle the problems that exist in the Mranggen III Health Center, namely being able to speed up service to patients and by using a multiuser-based information system. Leaders and several staff can access it simultaneously and quickly.

Building security is a mandatory requirement that must be met by a building. Before being built, it is necessary to review academic studies and structural analysis in advance regarding the technical requirements of the building whether it meets the standards or not against existing regulations in Indonesia. Currently, the Brebes Regency Education, Youth and Sports Office has an outdoor tennis court that is not yet representative. So it is planned that the field will be upgraded to become a semi-indoor field, by adding a curved roof in the 2022 fiscal year. The purpose of this community service activity is to determine the safety of semi-indoor roof coverings from a structural point of view. The method of activities carried out to achieve the goal of Community Service (PPM) is the method of literature, field surveys, data processing and report preparation.

Anemia during pregnancy is still a global problem. The government synergizes with health workers to reduce the prevalence of anemia, one of which is by administering iron supplements. However, this alternative has not been able to reduce the incidence of anemia in Indonesia. Therefore, the aim of this study was to determine strategies to reduce the incidence of anemia in pregnant women. Qualitative research with a single holistic case study approach. Research informants were heads of puskesmas, midwives, nutritionists, ATLM, doctors, and anemic pregnant women. Data collection for 1 month. Data analysis using Miles and Huberman models. The data collection instruments were interview guides, study documentation, observations, logbooks and field notes. The results of this study, there are 4 themes namely: 1) increasing the competence of human resources; 2) providing more comprehensive health education and simpler word choices; 3) Educational media innovation by utilizing online platforms; and 4) husband and family support. Therefore, increasing human resources can be through training and technical guidance on the management of anemia during pregnancy and anemia hematology examination, utilizing social media platforms such as Instagram, TikTok, Youtube and Whatsapp. increased blood especially drinks that can block the absorption of iron. Also, husbands encourage and remind pregnant women to regularly consume iron tablets every day.

The service focuses on training on processing glass waste as the main ingredient in making mosaic works, themed on folklore. Aims to provide knowledge about the potential of glass waste, and the technical practice of processing it to become a mosaic work. The training participants were a group of young people from Noloro, located in Sawit, Panggungharjo, Bantul DIY. The method used in the implementation is ADDIE, which stands for the stages of the process itself, namely Analysis, Design, Develop, Implement, and Evaluate. The result of the training is a mosaic work from glass waste, taking the theme of one of the folk tales from Bantul Regency, namely about the Krapyak Stage as well because it is a very iconic building.

Study table is one of the supporting learning activities but the current study table design is not in accordance with consumer needs, especially for children. The development of this study table product is expected to answer the needs of custumers or consumers and produce an ergonomic study table. This multifunctional learning folding table product uses the parameter measurement of the Quality Function Deployment (QFD). The result obtained based on the customer show that there are 7 attributes (customer requitment) and 4 technical parameters ( technical response). In this regard, the product development of a multifuntional folding study table uses the Quality Function Deployment (QFD) method using teak wood. This table also has several features, namely a reading light feature, a glass holder, a storange feature, equipped with a simple design, attaractive practical colors and ideal dimensions so as to increase comfort inusing the folding study table product.

An analysis of the uncertainty value of measuring spur gear dimensions using a profile projector has been carried out. Dimensions of spur gears measured are pitch diameter, root diameter and outside diameter. The manufacture of 3 samples of spur gears was first made with a shape milling machine based on the initial technical data that had been determined. Then measurements were made with a profile projector measuring instrument for the three measuring dimensions, the best repeated measurement average was found in the root diameter measurement for the PJ01 sample of 32.4053 mm with a standard deviation of 0.0077 mm. The uncertainty method used is statistically and applies only to a series of observations. Determination of the uncertainty value is done by performing repeated measurements five times on the same sample. This method refers to ISO GUM with type A evaluation. The uncertainty value obtained for the best measurement is 0.0034 mm with an expanded uncertainty of 0.0068 mm with a 95% confidence level.
