THE RELATIONSHIP OF SEA SURFACE TEMPERATURE (SST) TO RAINFALL IN THE WEST WATERS OF ACEH, INDONESIA

2025-05-05T08:16:17+00:00

Rainfall and sea surface temperature (SST) are closely linked in the global climate system. Sea surface temperature affects rainfall through water evaporation, which plays an important role in cloud formation and the hydrological cycle. As sea surface temperature increases, water evaporation also increases, increasing the chance of rainfall in certain regions, especially in the tropics. Conversely, in regions with cooler sea surface temperatures, evaporation decreases, resulting in lower rainfall. This internship aims to gain a deeper understanding of sea surface temperature and rainfall in the western waters of Aceh. This activity was carried out in August-November 2024, which took place at the Class I Sultan Iskandar Muda Meteorological Station office in Kuta Baro, Aceh Besar. The method used is descriptive analysis method, which is by collecting SST data and also rainfall. SST data is processed using GrADS until it can visualize the map. While data from rainfall is taken from BMKG data and processed using Excel. The results of the internship show that there are several factors for rainfall besides SST, in each region including latitude, altitude, wind patterns (trade winds and monsoon), land and water distribution, and mountains and high mountains. These factors greatly influence the variation and type of rainfall. Annual rainfall variations are influenced by global atmospheric behavior, tropical cyclones and others. Warm ocean temperatures in April and May increase air humidity which favors the formation of rain. However, the fluctuating rainfall shows that SST is not the only factor affecting rainfall. In June, while the SST remained high, rainfall was drastically reduced. This suggests that other factors, such as latitude, wind patterns and global atmospheric influences, play a significant role in rainfall variations.

TRAINING ON MAKING PAVING BLOCKS FROM CONCRETE WASTE TO IMPROVE THE ECONOMY

2025-04-30T07:34:38+00:00

This study aims to improve community skills in processing concrete waste into products with economic value, especially paving blocks, through training activities. Concrete waste which is generally considered useless and polluting the environment, is reprocessed into useful construction materials. The implementation method includes initial observation, training planning, activity implementation, and evaluation of results. Training activities are carried out with a participatory approach, involving the community directly in the process of mixing materials, molding, and drying paving blocks. The results of the study showed that this training succeeded in increasing the knowledge and skills of participants in producing paving blocks from concrete waste. In addition, participants began to see the potential for micro-businesses that could be developed from the results of this training. Economically, this activity opens up new opportunities to increase community income, especially in areas with high unemployment rates and limited access to formal employment. In conclusion, training in making paving blocks from concrete waste has proven effective as an innovative solution in waste management as well as a strategy for empowering the community's economy. It is hoped that this activity can be replicated in other areas as a sustainable effort to create a clean environment and an independent economy.

TRAINING ON WRITING PROPOSALS HIBAH DIKTI ABOUT COMMUNITY SERVICE FOR USCND LECTURERS

2025-06-21T17:39:58+00:00

The difficulty of lecturers in scientific publications is the low level of dedication and research conducted by lecturers. One of the causes of low research among lecturers, especially in the USCND environment, is the lack of national competitive PkM proposals that pass the selection. The purpose of this activity is to improve lecturers' knowledge and skills in compiling national competitive proposals. This community service activity will be carried out in several stages, namely 1) Coordination with all related parties, including the USCND Chancellor; 2) Training on compiling national competitive proposals; 3) Assistance in writing proposals; 4) Focus group discussions on several problems that occur, solutions and follow-up plans. At this stage, a comprehensive evaluation of the activity is also carried out. After participating in this activity, participants are expected to be able to make considerations for the national competitive PkM scheme, utilizing knowledge and information to support plans and facilitate the preparation of proposals.

IMPROVING DIGITAL LITERACY AND ADOLESCENT MENTAL HEALTH IN THE SOCIAL MEDIA ERA

2025-08-08T18:23:13+00:00

The rapid rise of social media usage among adolescents presents both opportunities and challenges, particularly concerning mental health and digital literacy. In the digital age, adolescents must navigate complex virtual environments while maintaining psychological well-being. This community service program aimed to enhance digital literacy and promote mental health awareness among school-aged adolescents in Aceh. The activity involved 25 participants aged 15–24, drawn from various schools and youth communities. Implemented over two days, the program employed a quasi-experimental design, combining interactive education, case discussions, and role-play simulations. Pre-test and post-test evaluations measured changes in participants' knowledge levels. The results indicated a significant improvement in understanding digital literacy and mental health concepts, as evidenced by a Wilcoxon test result of p = 0.010 (< 0.05). These findings underscore the effectiveness of interdisciplinary educational interventions in equipping adolescents with critical digital skills and emotional resilience in the era of pervasive social media. The program highlights the importance of collaborative efforts among educators, families, and communities in fostering safe, informed, and mentally healthy digital engagement among youth.

TRAINING AND IMPLEMENTATION OF THE SRIKANDI BACK-UP APPLICATION BASED ON THE ELECTRONIC FILING SYSTEM

2025-08-17T18:22:17+00:00

This community service activity aims to assist the Plantation Service of South Sumatra Province in addressing archive management challenges due to limited and often unstable internet connectivity. The primary archival management application in use is SRIKANDI, which relies on internet access. To mitigate the risks associated with this limitation, a backup system was developed using a simplified Microsoft Access-based Electronic Filing System (EFS) that operates offline. The community service project involved several phases: needs analysis, system design, staff training, implementation, and evaluation. Results showed that the backup system's features effectively supported archival management at the agency, improved retrieval efficiency, and enhanced data resilience against technical disruptions. Staff participating in the training quickly grasped and successfully operated the application.
