OKSIGEN TERLARUT DAN pH DI AIR SISIPAN SEDIMEN MANGROVE DAN PESISIR DI DESA BULUTUI KECAMATAN LIKUPANG BARAT

Abstract

This research was conducted in Bulutui Village, West Likupang District, related to the
problems raised how is the solubility of Dissolved Oxygen (DO) and the pH of sediment-inserted
water at mangrove locations, and on the coast, then this research aims to find out how the solubility of
oxygen (DO), and acidity (pH) of sediment-inserted water in mangrove ecosystems and on the coast
in Bulutui Village, West Likupang District. Based on the results of measurements that have been
carried out in Bulutui Village, West Likupang District, it was found that the value of the dissolved
oxygen content at the mangrove location was in the range of 0.36 – 1.98 ppm, with an average of
0.98 ppm, the pH value ranged from 6.16 – 6.89 with an average value of 6.04. In coastal locations,
the dissolved oxygen content ranges from 1.26 to 2.87 ppm, with an average of 2.09 ppm, the pH
value ranges from 6.78 to 8.90, with an average value of 8.34. The statistical t test showed that there
was a difference between the dissolved oxygen values in the sedimentary water in the mangroves
and the coast, as well as the acidity (pH).

ABSTRAK

Penelitian ini dilakukan di Desa Bulutui Kecamatan Likupang Barat, berkaitan dengan
permasalahan yang dikemukakan bagaimanakah kelarutan Oksigen Terlarut (DO) dan pH air sisipan
sedimen pada lokasi mangrove, dan di Pesisir pantai, selanjutnya penelitian ini bertujuan untuk
mengetahui bagaimana kelarutan oksigen (DO), dan keasaman (pH) air sisipan sedimen pada
ekosistem mangrove dan di pesisir di Desa Bulutui Kecamatan Likupang Barat. Berdasarkan hasil
pengukuran yang telah dilakukan di Desa Bulutui Kecamatan Likupang Barat ditemukan nilai dari
kandungan oksigen terlarut pada lokasi mangrove adalah berkisar 0,36 – 1,98 ppm, dengan rata
ratanya 0,98 ppm, nilai pH berkisar 6,16 – 6,89 dengan nilai rata rata 6,04. Pada Lokasi pesisir
dengan kandungan oksigen terlarut berkisar 1,26 – 2,87 ppm, dengan rata rata 2,09 ppm nilai pH
berkisar 6,78 – 8,90, dengan nilai rata – rata 8,34. Uji statistika t test menunjukkan adanya
perbedaan antara nilai oksigen terlarut pada air sisipan sedimen di mangrove, dan pesisir, demikian
juga keasaman (pH).
