This study was conducted by Muhammad Sangkot Pangidoan (Student ID: 20090033) under the title “The Effect of Product Quality on Business Development in the Culinary Sector at Rumah Makan Incor Laru, Tambangan District, Mandailing Natal Regency.” This quantitative research employed multiple linear regression analysis. Data were collected through questionnaires distributed to 96 respondents using a simple random sampling technique. The objective of this study was to determine and examine the effect of product quality on the business development of Rumah Makan Incor Laru. The research was carried out in Tambangan Tonga Village from December 2023 to August 2025. The independent variable in this study is product quality, while the dependent variable is business development. The results show that product quality has a positive and significant effect on business development, with a significance value of 0.000 < 0.05. The coefficient of determination (R²) is 0.522, indicating that 52.2% of changes in business development are explained by product quality, while the remaining 47.8% are influenced by other factors outside this study. The simple regression equation obtained is Y = 24.583 + 0.275X, with a t-count of 9.340 greater than the t-table value of 2.372, meaning the hypothesis is accepted.

A tumor is a collection of abnormal cells that develop due to excessive and uncontrolled cell division (Angkotasan & Vioneery, 2022). Currently, tumors are considered one of the leading causes of morbidity and mortality worldwide (Maryati, 2023). The purpose of this study is to provide an in-depth understanding and description of nursing care for Mr. T, a patient with a medical diagnosis of post-operative soft tissue tumor (STT) in the right arm, who was treated in Room Mawar 2 at RSUD dr. Soeselo, Tegal Regency, in accordance with standardized nursing care guidelines. This study employed a descriptive case study method, with data obtained through interviews, observations, physical examinations, and documentation reviews. Based on the case analysis, the patient’s main complaint was severe pain following surgery. Three priority nursing diagnoses were identified: acute pain, knowledge deficit related to the disease and its management, and risk of infection due to post-surgical wound. Nursing interventions were planned and implemented according to SDKI (Standar Diagnosa Keperawatan Indonesia), SIKI (Standar Intervensi Keperawatan Indonesia), and SLKI (Standar Luaran Keperawatan Indonesia), adapted to the patient’s condition. The interventions included pain management techniques, health education, wound care, and infection prevention strategies. The results showed that after the nursing care was carried out, the patient reported a decrease in pain intensity, demonstrated increased knowledge regarding his condition, and exhibited no signs of infection. This study highlights the importance of systematic nursing care in post-operative soft tissue tumor patients to reduce complications, promote recovery, and improve quality of life. The findings are expected to contribute as a reference for nursing practice and further research on tumor management in clinical settings.

The purpose of this community service activity is to strengthen the concept of electrolysis for students of SMAN 1 Suwawa through interactive laboratory exercises, as well as to enhance students' understanding and practical skills related to the electrolysis process. The partners involved in this activity include the Principal, Chemistry Teacher, and all 12th-grade students of SMAN 1 Suwawa. The implementation method of the activity involves four main stages: a pre-test to measure initial understanding, providing material to reinforce the concept of electrolysis, conducting interactive laboratory exercises using electroplating tools, and a post-test to measure the improvement in students' understanding. The results of this activity show a significant improvement in the understanding of electrolysis concepts, with an N-Gain value of 76.8%, indicating the effectiveness of this method in improving students' learning outcomes. Based on these findings, it is recommended to continue applying interactive laboratory approaches in science education in secondary schools, as well as utilizing technology and interactive modules to support students' understanding of complex chemical concepts. Additionally, teacher training is also important to ensure the sustainability of effective laboratory-based learning.

Angkot is one of the conventional forms of transportation that is often used by the public for mobility because the prices are affordable with a variety of routes and a lot of cargo.
