Abstract

Nata de coco is food made from coconut water waste which can be consumed and can help improve the digestive process. The results of fermentation at PT XYZ still contain damaged or moldy nata sheets. The purpose of this study is to identify the causes of nata sheet defects. The identification of production defects in this study uses a fishbone diagram. The results of this study show that the cause of nata de coco sheet defects is the quality of coconut water that is too old (contains oil), too young (does not contain minerals), too long exposure to open air (contaminated with other bacteria). So that the resulting starter seeds are not good enough. Other causes are because the tray used is not clean (still runny), the newspaper used is torn (wide open), shocks occur during fermentation, alkaline pH, fluctuating air temperature, the boiling process has not reached boiling point, and the amount of additional materials (ZA fertilizer and sugar) is not quite right.

Abstract

This study optimizes resource allocation in Islamic banking using Design of Experiments (DOE) and Orthogonal Arrays (OA) to minimize simulation scenarios while ensuring statistical validity. Focusing on a West Aceh-based bank (4 tellers, 2 CS agents, 5 ATMs), the research addresses operational inefficiencies prolonged queues, resource misalignment conflicting with Sharia principles of efficiency (israf avoidance) and equity, exacerbated by seasonal demand fluctuations. A Full Factorial Design initially generated 40 scenarios (200 iterations), imposing high computational burdens. OA techniques reduced scenarios to 9 (77.5% fewer iterations, 45 total), maintaining a 95% confidence level (z-score=1.96) and 1-minute margin of error. Utility differences between methods were marginal (CS:1.3%, Teller:1.5%, ATM:2.3%) and statistically insignificant, confirming OA’s reliability. Critical interactions (e.g., CS=1 paired with all Teller levels) and balanced configurations (Teller=3 + ATM=3 “sweet spot”) were identified, despite minor imbalances (e.g., ATM=4 tested once). The approach advocates data-driven policies deploying ATMs during CS shortages and optimizing human-technology ratios aligning with Sharia ethics by reducing waste and enhancing equity. With 77.5% computational savings, this methodology offers scalable solutions for Islamic finance and dynamic sectors, bridging statistical rigor with ethical governance in resource optimization.

Abstract

This community service activity is part of the Regular Community Service Program (KKN) held in Lancong Village, Sungai Mas District, West Aceh Regency. The focus of this activity is to increase elementary school students' awareness of the dangers of bullying, strengthen clean and healthy living behaviors (PHBS), and develop creativity in the learning process. The background of this activity is based on the still low understanding of some students about the negative impacts of bullying, lack of habits of maintaining personal hygiene, and limited channels for expressing creative ideas in schools. The activity was carried out at Lancong Public Elementary School involving students in grades 4 to 6 through an interactive educational approach. The methods used included informative presentations, educational games, group discussions, and creative practice in the form of making thematic posters. The session on bullying was aimed at providing an understanding of the forms of bullying, its impact on victims and the school environment, as well as prevention and handling strategies. PHBS material was delivered through demonstrations of how to wash hands properly, maintain a clean classroom environment, and the implementation of a healthy lifestyle every day. In the creativity development section, students were invited to express anti-bullying and PHBS messages through posters that were then presented in front of their peers. The results of the activity showed an increase in students' understanding of the importance of mutual respect, avoiding bullying, and practicing healthy lifestyles. Furthermore, students' skills in expressing ideas creatively also developed, as seen from the enthusiasm and quality of the posters produced. This program has had a positive impact on shaping positive attitudes and habits in the school environment, while also serving as a model for educational activities that can be implemented in other schools. Thus, this activity contributes to the holistic development of students' character, encompassing social, health, and creativity aspects.

Abstract

Every company competes by developing strategies to outperform its rivals in the same market, whether through variations in the products offered, promised facilities, or the quality of services delivered to customers.
