Abstract

Kopi Naka is a micro, small, and medium enterprise (MSME) operating in the coffee beverage sector, located in Tarakan, North Kalimantan. Kopi Naka produces several signature iced coffee variants, namely Naka (Milk Coffee), Naren (Palm Sugar), Namel (Caramel), Nalla (Vanilla), Nacho (Chocolate), and Nalo (Milo). In its daily operations, production quantities are still determined based on estimated demand, which often leads to suboptimal results. This study aims to optimize the production of Kopi Naka's signature menu using the goal programming method with the assistance of the POM-QM version 5.2 software. The objectives to be achieved include fulfilling the targeted production quantity, minimizing production costs, and maximizing profits. The optimization results indicate that all priority goals can be optimally achieved. The production capacity target of 1,400 cups per month can be met through a recommended production combination of 1,355 cups for the Naka variant and 45 cups for the Nacho variant. Through this production combination, Kopi Naka MSME can achieve an optimal profit target of IDR 3,245,000 per month, with an efficient production cost utilization of IDR 11,200,000 per month (achieving a savings of IDR 40,000 from the total estimated cost constraint of IDR 11,240,000).

Abstract

This community service program aims to strengthen environmental awareness and literacy among coastal children through a participatory educational approach in RT 05 Pantai Amal, Tarakan City. The program involved children aged 6–12 years who participated in a series of integrated activities combining environmental education and literacy-based learning. Visual media, interactive discussions, and picture storybooks with environmental themes were used to create a learning process that was close to the children’s daily experiences. Observational data showed a significant increase in children’s understanding of coastal environmental conditions, their awareness of waste issues, and their willingness to engage in pro-environmental behavior. At the same time, literacy activities encouraged greater interest in reading, improved confidence in expressing ideas, and enhanced participation in group discussions. The integration of environmental awareness and literacy proved effective in shaping positive character traits, including responsibility, social awareness, and critical thinking. These findings indicate that participatory, context-based education can serve as an effective strategy for empowering coastal children and fostering sustainable values from an early age.
