Pemanasan global merupakan isu penting bagi semua negara di dunia karena memberikan dampak negatif bagi masyarakat dunia dan juga semua organisme di darat dan laut. Generasi muda saat ini perlu mengetahui dengan jelas dan benar apa yang dimaksud dengan pemanasan global, faktor penyebab terjadinya pemanasan global dan usaha-usaha yang harus dilakukan untuk mengurangi laju proses pemanasan global yang terjadi saat ini. Tujuan dari program Pengabdian Kepada Masyarakat ini adalah mengedukasi generasi muda khususnya siswa SMA negeri 11 Ambon tentang pemanasan global dan dampaknya bagi kehidupan manusia. Metode yang digunakan dalam melaksanakan program Pengabdian Kepada Masyarakat ini adalah dengan cara pre test, penyajian materi, diskusi, tanya jawab dan post test. Hasil analisis dari pre test dan post test menunjukan hanya 32% siswa yang memberikan jawaban yang benar saat pre test dan saat post test mengalami peningkatan menjadi 55%. Hal ini menunjukan bahwa kegiatan sosialisasi ini memberikan dampak peningkatan pengetahuan siswa tentang pemanasan global. Kegiatan PkM harus terus ditingkatkan implementasinya kepada siswa di semua jenjang mulai dari sekolah dasar sampai dengan sekolah menengah atas di pulau-pulau kecil di provinsi Maluku. Hal ini akan meningkatkan pengetahuan generasi muda tentang pemanasan global dan hal ini dapat menjadi salah satu metode untuk memperlambat proses pemanasan global yang terus terjadi saat ini.

Nitrous oksida (N2O) merupakan salah satu gas rumah kaca (GRK) yang berpotensi menimbulkan pemanasan global (GWP) sebesar 298 kali dibandingkan CO2. Ekosistem mangrove mempunyai fungsi ganda yaitu dapat menyerap dan menghasilkan GRK. Salah satu wilayah yang merupakan habitat mangrove adalah pesisir pantai Poka yang terletak di Teluk Ambon Dalam. Informasi mengenai emisi dan potensi pemanasan global dari gas N2O pada sedimen mangrove yang ada di pesisir pantai Poka sampai saat ini belum ada. Penelitian bertujuan untuk mengetahui nilai emisi gas N2O dan potensi pemanasan global pada sedimen mangrove di pantai Poka, Teluk Ambon. Pengambilan sampel gas dilakukan dengan menggunakan spoit melalui syringe pada sungkup yang diletakkan di bawah kanopi mangrove. Analisis konsentrasi gas N2O menggunakan metode kromatografi gas dan rata-rata perbedaan konsentrasinya diuji dengan ANOVA single factor. Hasil penelitian menunjukkan bahwa emisi gas N2O terbesar pada sedimen mangrove di pantai Poka terdapat pada tipe pasir berlumpur, dan terendah terdapat pada pasir. Total GWP pada sedimen mangrove pantai Poka yaitu 13.6 mg/m2/jam yang dikontribusikan oleh tipe substrat lumpur lumpur berpasir sebesar 5.21 CO2e mg/m2/jam, pasir berlumpur sebesar 6.31 mg/m2/jam, dan pasir sebesar 2.08 CO2e mg/m2/jam.

It is important to maintain a healthy marine ecosystem to support eco-friendly and sustainable fishery development. Implementation of Ocean Health Index (OHI) started globally in 2012, and it has been strongly recommended to be conducted at all levels: locally, nationally, and regionally. Indonesia has modified OHI for its national assessment, which its called Indeks Kesehatan Laut Indonesia (IKLI). IKLI has been estimated since 2020 and introduction applied at the sub-national level. This study is an attempt to implement IKLI in Maluku province with the main objective is to estimate score of a partial IKLI, based on clean waters (goal no. 9) and biodiversity (goal no. 10). Samples were taken from Ambon and Baguala Bays between June and September 2022. For clean water goals, the parameters used were concentration of phosphate, nitrate, silicate, dissolved oxygen (DO), pH, and the number of ports that implemented green principles. The parameters of water quality of silicate, DO and pH in those two bays are within the range of government-mandated standards, except for nitrate and phosphate concentrations which are not. For the biodiversity goal, the parameters used are the species composition of mangrove, seagrass, fish, and coral. The IKLI biodiversity score was low due to the high level of human activity pressure at the two selected study sites. This study demonstrates the applicability of the IKLI in a partial analysis, and its usefulness in highlighting existing data and knowledge gaps. The study suggests that a comprehensive IKLI assessment should be conducted in Maluku Province. Meanwhile to improve the national-level IKLI assessment, actions should prioritize improving water quality management, expanding marine protected areas, and monitoring coastal ecosystems, especially those heavily affected by human activities.KeywordsArchipelagonutrientOHIIKLI Maluku

The organic material input that enters the waters of Ambon Bay spreads to the mangrove ecosystem area and is partially deposited in sediments, including the mangrove area of Poka Village. This study aims to analyze greenhouse gas emissions (CO2 and CH4) in mangrove sediments in the Poka Village area. The gas collection was carried out using a cylindrical cap method placed on three types of sediment, namely sandy silt (LPs), muddy sand (PsL), and sand (Ps). Gas concentration analysis refers to the gas chromatography method. The results showed that the largest CO2 emissions were found in LPs sediments, 138.94 mg/m2/hour. Meanwhile, the lowest emission was found in PsL sediment, which was 20.69 mg/m2/hour. In addition, the largest CH4 emission was also found in the LPs sediment type, 0.2154 mg/m2/hour. Meanwhile, the lowest CH4 emission was found in the Ps sediment type, 0.0447 mg/m2/hour. Greenhouse gas emissions (CO2 and CH4) in mangrove sediments on the Coast of Poka, Ambon Bay, are still relatively low compared to Indonesia's average emissions from other mangrove ecosystems. The sandy-mud sediment type has greater emissions than the silty-sand and sand sediment types which are influenced by the availability of total organic carbon in each mangrove sediment.

People's awareness of the marine environment should be started by the student in Elementary School. The public service program was conducted to increase student knowledge of the marine environment and the fisheries resources and also to protect that. This program consists of giving a lecture, discussion, and evaluation to the student of SD Negeri 2 Oma, Haruku Island Regency, Central Maluku. The topics consist of the marine environment and the importance of this environment, types of the shore, marine mollusc resources (definition and clasification), economically important molluscs, marine Gastropoda which consumed by local people, and how to protect the marine environment and its resources. Based on the evaluation, student knowledge increased from <30% before socialization to >90% after socialization. It means that education processes for the elementary student about the problems of the marine environment and its resources increase significantly, and need more information on other marine resource.
