Abstract

The existence of mangrove in coast areas have both ecologic and physical important functions.  Mangrove is a high productive ecosystem. Litters from fallen leaves and twigs are organic sources for macrozoobenthic life.  The aim of this research was to determine the response of macrozoobenthics on total organic matter content and other chemical-physico characters of sediments due to differences in mangrove conditions. This research was conducted from May to September 2016 in Sub-district of Ampallas, Distric of Mamuju, Province of West Sulawesi, Indonesia. Sediments in 20 cm2 transects were collected using small shovel to obtain the macrozoobenthic samples. The sediments contained macrozoobenthics were sieved using a 1 mm mesh size sieve net. Four sampling sites were chosen, each to represent areas with no mangroves, low, medium, and high densities.  The total of organic matter samples were collected using 2 inch diameter of PVC pipe cores, which were analyzed further using Loss by Ignition method.  Besides total of organic matter, several parameters (i.e. redox potential, sediment pH, salinity, temperature, and dissolved oxygen) were measured.  The results showed that gastropods dominated the existed macrozoobenthics.  Gastropods and oligochaete lived in greater amounts in high mangrove density site with higher organic matter content and fine substrate.Keywords: mangroves, macrozoobenthics, organic matter, Distric of Mamuju

Abstract

Mangroves have numerous ecological functions as well as economical values. In order to achieve successful of mangrove restoration and regain its functions, understanding on the factors affecting the establishment of mangroves are required. This study examined the characteristics of physico-chemical factors from three compartments (sediment, interstitial and seawater) that associated with different mangrove densities in Ampallas, District of Mamuju, West Sulawesi. The Principal Component Analysis and Spearman correlation analysis showed that high densities of adult and seedling mangroves strongly correlated to higher organic contents, dissolved oxygen of interstitial water, seawater salinities and lesser pH of sediments, seawater and interstitial. The reverse conditions applied for the less mangrove densities and control site that had no mangrove. In most cases, there were reciprocal relationships amongst the studied variables.Keywords: chemical-physical factors, density, mangroves.

Abstract

The study was to determine the concentrations of Zn in porewater and fine roots of Rhizophora sp., and to examine their interactions with mangrove densities and physico-chemical. Porewater samples, fine roots,  and sediments were collected in a 100 m2 plot at each site with different mangrove densities. The average Zn concentrations in mangrove roots in the study area were 0 – 58.21 mg/kg, suggested the capability of mangrove roots in retaining Zn. The average dissolved Zn concentrations in porewater were 0.63 mg/L – 3.50 mg/L, illustrated the amount of Zn bioavailable form and its potential release to the adjacent environment. The Zn concentrations in porewater did not correlate significantly with the densities of mangroves. The concentrations of Zn in roots increased as the densities were higher, which is possibly caused by the absence of mangrove at Site 1. The study discovered the important roles of organic content and silt/clay in Zn sorption thus affect Zn levels in porewater. The concentrations of Zn in mangrove roots increased as the pH of sediment and porewater decreased.

Abstract

Penelitian ini bertujuan mengetahui aktivitas antibakteri, konsentrasi efektif, dan pengaruh peningkatan konsentrasi ekstrak etanol daun kari (Murraya koenigii) terhadap daya hambat pertumbuhan bakteri Staphylococcus aureus, Escherichia coli dan Pseudomonas sp. Ekstraksi dilakukan dengan cara maserasi menggunakan pelarut etanol 96%. Pengujian aktivitas antibakteri menggunakan metode difusi agar. Parameter yang diukur adalah besarnya diameter daya hambat yang terbentuk di sekitar kertas cakram. Hasil  uji aktivitas antibakteri dianalisis dengan metode one way anova dilanjutkan dengan uji Duncan. Hasil penelitian menunjukkan bahwa konsentrasi ekstrak 12,5; 25; dan 50% telah memberikan aktivitas daya hambat pertumbuhan bakteri uji. Konsentrasi efektif yang dapat menghambat bakteri Staphylococcus aureus dan Escherichia coli pada konsentrasi 50%, sedangkan bakteri Pseudomonas sp. pada konsentrasi 12,5; 25; dan 50%. Peningkatan konsentrasi ekstrak daun kari menunjukkan semakin luas diameter zona hambat pertumbuhan bakterinya. Penghambatan yang terjadi pada bakteri Staphylococcusaureus, Escherichia coli, dan Pseudomonas sp. tersebut, membuktikan bahwa daun kari mengandung senyawa aktif yang bersifat antibakteri, seperti flavonoid, fenol, alkaloid, dan saponin.
