Abstract

Cities that grow on an island have limitations in utilizing space for various activities. The limited space of island activity, population growth, and high urban activity have signaled the need to analyze the optimal capacity of island cities. With the Ternate City case study, this study aims to determine the capacity of island cities economically by analyzing the optimal size of island city residents. The optimal measurement of island cities uses the Alonso-Richardson approach, minimum management cost, net benefit, and long-term profit. The results of the analysis showed that the city of Ternate, with a population density of 1,264 people / km2 per the year 2020, has exceeded the optimum capacity of the size of the city both from the minimum per capita city management fee (658 people/km2) and from the maximum approach of per capita benefits (877 people/km2). While from the long-term maximum per capita profit approach, the city's population is still below the optimum limit (2,054 inhabitants/km2). Thus, strict population control is essential, especially on Ternate island, through the spread of residents and activities directed to islands or sub-districts whose urbanization is still below the optimum point of the city population.

Abstract

The utilization of coconut waste, particularly coconut shells, in Kaiyasa Village, North Oba Subdistrict, Tidore Islands City, remains suboptimal because the waste is commonly discarded or burned without generating economic value. Limited knowledge, technical skills, and access to market information are major barriers to developing this local commodity. This Community Service (PKM) program aims to improve the knowledge, skills, and management capacity of the Kaiyasa Village community in processing coconut shell waste into high-value charcoal and strengthening village-based microenterprise governance. The program employed an interactive participatory approach through five stages: awareness raising and perception alignment; management and technical training; appropriate technology implementation through standard operating procedures and simple financial records; intensive mentoring and evaluation; and development of a sustainability plan. Fifteen coconut farmers actively participated. The results showed improved knowledge and skills in waste processing and business management. Applying circular economy principles increased the value of coconut shells from Rp700/kg to Rp4,500/kg, providing an economic buffer when copra prices fluctuate. The program also established foundations for a structured, transparent, and sustainable business group.
