Abstract

Cibitung Hamlet, Ponggang Village is one of four partner villages of the Industrial Engineering Study Program of Atma Jaya University (UAJ) in community service activities. Continuing economic development for Ponggang Village, the community service team saw an opportunity in Cibitung Hamlet to plant water spinach as a selling product and increase vegetable consumption for the Ponggang Village community. To support the planting of water spinach, fertile soil, sunlight, and water are needed. Fertilization is really necessary to increase or maintain plant fertility by adding artificial or natural nutrients. The Community Service Team conducted a preliminary study on the effect of organic fertilizers, inorganic fertilizers, fertilizers from biogas dregs (bioslurry), and no fertilizers, using the soil in Cibitung Hamlet on the growth of water spinach. Based on the results of the study, fertilizers using biogas dregs provided heavy metal content values below the limit and also provided a fairly good level of water spinach growth compared to the treatment of organic fertilizers, inorganic fertilizers, and no fertilizers. The results of his study were socialised to the community of Cibitung Hamlet, Ponggang Village in the form of community service

Abstract

Learning mathematics, especially arithmetic and number patterns, is often a challenge for students due to the lack of creative approaches and the use of technology in the learning process. This community service program aims to improve the competence of teachers and lecturers in teaching innovative arithmetic concepts through the Educational Technology Online Workshop: Creative Arithmetic in the Era of Artificial Intelligence. This activity is conducted online and attended by participants from various backgrounds, including teachers, students, and the general public. The implementation method includes introducing the concept of regularity of number patterns, demonstrating the Vertical Metric method, and training in using web-based digital applications for creative calculations from licensed association partners. The activity results showed an increase in participants' understanding of developing creative learning strategies and high enthusiasm from participants in implementing technology-based arithmetic methods in their respective educational environments. This training positively impacts educators' pedagogical skills and encourages students' interest in learning mathematics through a more interesting and applicable approach.

Abstract

"Kemah Peduli Sahabat Kasih" is a care facility for individuals with mental disorders, managed by a single family. One of the primary challenges faced by the facility is the inadequate lighting for nighttime activities. In 2024, the team from the Faculty of Biosciences, Technology, and Innovation (FBTI) at Atma Jaya Catholic University of Indonesia contributed by installing two solar-powered lighting units: one along the access road to the facility and another for the front and back yard areas. However, these two lighting points were insufficient to fully support nighttime activities. Therefore, the 2025 community service program aimed to install additional lighting points at the Kemah Peduli Sahabat Kasih facility. The activity began with observations and interviews with the head and staff of the facility to assess conditions following the installation of the initial lighting units and to determine the additional lighting needs. It was found that three more lighting points were required, exceeding the initially allocated budget. As a result, a joint discussion was conducted between the Atma Jaya team, the facility head, and staff to decide that this year’s budget would be allocated to the purchase of solar-powered lamps. The community service program successfully procured three solar-powered lamps, which were tested and demonstrated satisfactory performance and illumination levels. The operational procedures and maintenance guidelines were also effectively communicated and understood by the facility’s head and staff.

Abstract

Southwest Sumba Regency is located in the province of East Nusa Tenggara, part of the Sumba Islands, which are famous for their natural beauty. This area offers a unique combination of stunning landscapes, distinctive cultural richness, and community life that still upholds local traditions. However, behind all that, there are several fundamental problems that still occur in Southwest Sumba Regency, especially stunting. Stunting is the main problem in this location. Stunting is chronic malnutrition in toddlers, which results in stunted growth in both height and weight. One of the factors causing stunting is the lack of access to clean water and proper sanitation. Clean water is very important in maintaining personal hygiene, food, and the environment so that it can prevent various diseases that can inhibit children's growth. The construction of drilled wells is one effective solution to overcome the problem of access to clean water in areas prone to stunting. With the existence of drilled wells, the community will have easier access to clean water so that it can improve the quality of life and health, especially for children. From the identified problems, the solution offered is the procurement of drilled wells with solar-powered pumps (PLTS). Thus, the problem of access to clean water and energy sources to operate the drilled well can be resolved. Then it can be developed in various locations/areas that have not received access to water. The capacity of the drilled well that has been made produces an output of 50 liters/hour. This output has been in accordance with the target of devotion.

Abstract

The long patient waiting time in general outpatient services has become a major problem at Clinic XYZ, particularly during the screening stage and doctor consultations at peak hours. This condition negatively affects patient satisfaction and service effectiveness. This study aims to identify the causes of prolonged waiting times, propose alternative improvements, and evaluate the effectiveness of solutions through simulation using ProModel software. The simulation model was developed to represent real conditions and test several improvement scenarios. The results show that nearly 50% of patients’ time in the system is spent waiting. Four improvement proposals were suggested, namely adding more doctors, redistributing nurses’ tasks, increasing screening capacity, and implementing a single-queue system. The best proposal, which applies consistently to both morning and afternoon sessions, is the addition of doctors. Based on the analysis, this solution proved to be the most effective, reducing total waiting time by 39.75% in the morning scenario and 33.74% in the afternoon scenario. This recommendation provides a strategic basis for improving service efficiency and patient satisfaction at Clinic XYZ.
