Abstract

This research was conducted from January to March 2021 in the seagrass ecosystem of Amahai village, Maluku Tengah Regency. This study aims to analyze the structure of seagrass communities, identify utilization forms of the seagrass ecosystem, and formulate management directives in Amahai waters. Environmental parameter measurements included temperature, salinity, pH, current speed, and substrate conditions. Data collected to analyze the forms of ecosystem use were carried out in observation and interviews. Management directives were devised descriptively based on the results. The study shows that six types of seagrass are found, namely Enhalus acoroides, Halophila ovalis, Thalassia hemprichii, Cymodocea rotundata, Halodule pinifolia, and Syringodium isoetifolium. The highest value of species density, frequency, and proportion of closure is represented by Thalassia hemprichii which are 64.22 stands/m2, 0.74, and 17.77%, respectively; while the lowest value for species density and frequency is Syringodium isoetifolium that totals 11.69 stands/m2 and 0.15. Halophila ovalis takes the minor portion of closure at almost 5%. The water quality parameters measured are temperature, salinity, pH, and current speed ranging from 27 to 3oC, 26 ‰ to 32 ‰, 7 to 8, and 0.20 to 0,46 m/s. In addition, the sandy category dominates the substrates. People utilize the ecosystem for activities such as bameti/balobe, mariculture, fishing, tourism, and boat mooring. Three management directives are formulated to manage the waters.

Abstract

Awareness of the importance of preserving coastal and marine environments can be fostered through various channels. The objective of this community service program (CSP) is to cultivate environmental awareness among adolescents in Negeri Hutumuri, Ambon. The CSP activities were conducted on July 7, 2025, with 52 participants aged 10–15 years. The method used in this CSP is an interactive approach. Materials are presented using images and videos to capture attention and make them easy to remember. The videos shown feature teenagers who are caring and passionate about coastal and marine environments. As a result, participants will be motivated to think critically. Participants were divided into groups to demonstrate their concern and commitment through drawings and sentences on paper, which would later be presented. The participants were highly enthusiastic about participating in this CSP and expressed a desire to become environmental agents within their families and communities.

Abstract

Ekosistem mangrove di Kawasan Wisata Kairatu Beach terletak di pusat aktivitas wisata dan memiliki peran penting dalam menjaga keseimbangan ekologi pesisir. Namun, pemanfaatan sumber daya mangrove yang berlebihan tanpa mempertimbangkan aspek ekologis berpotensi mengancam keberlanjutan ekosistem tersebut. Penelitian ini bertujuan untuk menganalisis kondisi bioekologis, bentuk pemanfaatan, serta merumuskan strategi pengelolaan komunitas mangrove di kawasan wisata Kairatu Beach. Penelitian dilaksanakan pada Januari–Mei 2025 melalui observasi lapangan dan wawancara. Pengambilan sampel mangrove dilakukan dengan metode line transect, sedangkan analisis bentuk pemanfaatan dan arahan pengelolaan menggunakan metode SWOT. Hasil penelitian menunjukkan bahwa parameter lingkungan seperti suhu, pH, dan salinitas masih berada dalam kisaran baku mutu, sementara nilai DO belum memenuhi standar kualitas perairan. Substrat di lokasi penelitian didominasi oleh lumpur berpasir. Ditemukan 8 jenis mangrove sejati dan 4 jenis mangrove ikutan, dengan tingkat kerapatan yang secara umum tergolong baik. Analisis menggunakan hemispherical photography menunjukkan variasi tutupan kanopi antarstasiun. Aktivitas pemanfaatan utama di kawasan ini meliputi pembangunan cottage, restoran dan kafe, wahana air, budidaya, serta penangkapan ikan. Berdasarkan hasil analisis, dirumuskan delapan strategi dan enam belas arahan pengelolaan untuk mendukung keberlanjutan ekosistem mangrove di kawasan wisata tersebut.
