Abstract

Organic matter is one indicator of environmental fertility both on land and at sea. The content of organic matter in a certain amount can be useful for aquatic biota, but if the amount of organic matter exceeds the assimilation capacity of the waters, it can cause a disturbance. This study aims to determine the organic matter content of water and sediment at high and low tide conditions in the waters of the east coast of Bengkalis Island and to determine the relationship. The method used is a survey method that is carried out in the field directly to collect data and samples, which are then taken to the laboratory for analysis. The results showed that the organic matter content of water at high tide was 17.38-25.28 mg/L and at low tide, it was 29.63-35.55 mg/L. The organic matter content of sediments at high tide conditions ranged from 2.28-5.37% and at low tide, conditions ranged from 3.46-8.62%. These conditions indicate that the organic matter content of water and sediment has not passed the predetermined threshold. The results of the analysis of the relationship between the organic matter content of water and sediment at high tide conditions with a coefficient of determination (R2) of 0.533 with a correlation coefficient (r) of 0.730 and at low tide with a coefficient of determination (R2) of 0.713 with a correlation coefficient (r) of 0.844. The type of sediment that dominates the waters of the East Coast of Bengkalis Island is mud.

Abstract

Buah pedada merupakan buah mangrove yang hidup di perairan payau yang banyak tumbuh di daerah pesisir, khususnya di Kabupaten Bengkalis yaitu di Kecamatan Bandar Laksamana Desa Sepahat. Bagian dasar buah pedada dibungkus oleh kelopak bunga, dan tidak beracun. Masyarakat Desa Sepahat jarang mengkonsumsi langsung buah Pedada karena rasanya yang asam sehingga banyak terbuang sia-sia. Buah tersebut memiliki kandungan gizi yang belum dimanfaatkan. Selain dapat dikonsumsi secara langsung Buah Pedada dapat juga diolah menjadi produk pangan bernilai jual tinggi seperti selai, sirup, dan permen karena kandungan vitamin C yang cukup tinggi. Dengan melihat potensi ini, maka muncul ide untuk membuat teknologi olahan pangan buah Pedada sebagai olahan bernilai jual tinggi. Tujuan kegiatan pengabdian kepada masyarakat ini akan memberikan nilai tambah yang besar ditinjau dari hasil teknologi produk pangan , sehingga menambah nilai ekonomis dan penghasilan bagi Masyarakat Desa Sepahat, serta meningkatkan pengetahuan masyarakatnya. Metode yang digunakan dalam kegiatan ini penyuluhan manfaat dan pengolahan buah Pedada. Kegiatan ini menghasilkan produk olahan buah pedada berupa sirup, selai, dan permen serta meningkatkan kreativitas sumber daya manusia di Desa Sepahat, Kecamatan Bandar Laksamana, Kabupaten Bengkalis untuk membuat industri rumah tangga produk pangan.
