Environmental Quality in Mangrove Stands in Mondulambi Forest Block, Manupeu Tanah Daru National Park: Kualitas Lingkungan pada Tegakan Mangrove di Blok Hutan Mondulambi, Taman Nasional Manupeu Tanah Daru

Abstract

English

Mangrove ecosystems are dynamic and vulnerable to external factors such as temperature, pH, and salinity. Changes in the quality of the environment and external conditions of the mangrove ecosystem can affect the arrangement of vegetation, species diversity, and the health and vulnerability of an ecosystem. The research aims to determine the environmental quality of external factors in the mangrove ecosystem by incorporating supporting data such as biota associations and pollutants. Measurement of environmental quality is carried out on plots of systematically dispersed samples representing ecosystems. The quality of the environment is measured using several parameters, such as temperature, salinity, pH, substrate thickness, and stagnation height, and the data is analyzed using observational and quantitative descriptive methods. The environmental quality conditions of the mangrove ecosystems in the Mondulambi Block, RPTN (National Park Management Resort) Kambatawundut, SPTN (Section of National Park Management) II Lewa, Manupeu Land Daru National Park cover salinity values ranging from 20-30 ‰ (ideal), soil pH ranges from 5-6.5 (tends to be more acidic), water pH ranges from 6-7.5 (optimal), the soil temperature ranged between 25-28°C, the water temperature ranging between 26-29°C (tendered to be lower), the lowest substrate thickness of about 2 cm and the highest thickness of 80 cm, the highest standoff height of about 9 cm, and the lowest standoff heights of around 2 cm. The results of this study describe the conditions of an ecosystem intended to be ideal.

Bahasa Indonesia

Ekosistem mangrove merupakan ekosistem yang dinamis dan rentan dipengaruhi oleh faktor eksternal seperti suhu, pH, dan salinitas. Perubahan pada kualitas lingkungan dan keadaan eksternal pada ekosistem mangrove dapat memengaruhi susunan vegetasi, keanekaragaman jenis, hingga kesehatan dan kerentanan suatu ekosistem. Penelitian ini bertujuan mengetahui kualitas lingkungan dari faktor eksternal pada ekosistem mangrove dengan menyertakan data penunjang berupa biota asosiasi dan pencemar. Pengukuran kualitas lingkungan dilakukan pada plot sampel yang tersebar secara sistematik mewakili ekosistem. Kualitas lingkungan yang diukur menggunakan beberapa parameter diantaranya suhu, salinitas, pH, ketebalan susbtrat, dan ketinggian genangan adapun data tersebut dianalisis dengan metode observasi dan deskriptif kuantitatif. Kondisi kualitas lingkungan pada ekosistem mangrove di Blok Mondulambi, RPTN (Resort Pengelolaan Taman Nasional) Kambatawundut, SPTN (Seksi Pengelolaan Taman Nasional) II Lewa, Taman Nasional Manupeu Tanah Daru meliputi nilai salinitas berkisar 20-30 ‰ (ideal), pH tanah berkisar 5-6.5 (cenderung lebih asam), pH air berkisar 6-7.5 (ideal), suhu tanah berkisar 25-28°C, suhu air berkisar 26-29°C (cenderung lebih rendah), ketebalan substrat terendah sekitar 2 cm dan ketebalan tertinggi 80 cm, ketinggian genangan air tertinggi sekitar 9 cm dan ketinggian genangan air terendah sekitar 2 cm. Hasil dari penelitian ini menggambarkan kondisi ekosistem mangrove tersebut dalam keadaan yang cenderung ideal.
