Abstract

This study aims to determine the perception of coastal communities in Central Tapanuli towards waste management as an effort to maintain marine sustainability and formulate waste utilization activities as an effort to increase the income of coastal communities in Central Tapanuli. The research method used in this study is a mixed research method. This study was conducted in three locations, namely in Lubuk Tukko Baru Village and Muara Nibung Village, Pandan District and in Jago Jago Village, Badiri District with a total of 100 respondents in the study. Based on the results of the study, the results of the perception of "community understanding of waste management in coastal areas" were obtained with an overall average value of 91.16%, meaning that all respondents strongly agreed or understood very well. Then for the results of the perception of "understanding of coastal environmental cleanliness and waste utilization to increase family income" the overall average result was 53%, with the category sometimes or less understanding. Then the results of several activities were obtained that were appropriate for coastal communities in Central Tapanuli Regency in utilizing waste as an effort to increase income with the management categories divided between organic waste and non-organic waste. Organic waste is very possible to be used for maggot cultivation activities or commonly called Black Soldier Fly (BSF) maggots and making candles and soap for households from used cooking oil. Then for non-organic waste, it is very possible to carry out activities to form a Waste Bank, establish a skills center that provides economic added value, and implement cooperation with private and government companies in managing non-organic waste.

Abstract

Mangure Lawik is a maritime hospitality activity developed by the ancestors of the Sibolga community and has been passed down continuously from one generation to the next. However, some people in Sibolga have experienced changes following the wave of modernization and have begun to abandon their customs. This paper aims to examine the history of Mangure Lawik, analyze the roles, interests, and influences of each stakeholder, and see the impact of this tradition on marine resources using ethnographic methods assisted by Stakeholder Analysis, it was concluded that the history of Mangure Lawik is divided into three periods (early, middle & present). This study also shows that there are 17 stakeholders consisting of 5 main stakeholders, 6 primary stakeholders, and 6 secondary stakeholders. The role of stakeholders is divided into four categories, namely: Policy Makers, Coordinators, Facilitators, and Implementers, where each stakeholder has carried it out well so that the Mangure Lawik tradition can continue. In its implementation, Mangure Lawik impacts the diversity of coastal and marine resources, because it indirectly invites the community to manage and protect coastal and marine resources, maintain the balance of aquatic ecosystems, and prevent coastal environmental pollution.
