Abstract

The river is one of the natural resources that are beneficial to human life, such as in agriculture and aquaculture processes, particulary in the Jeneberang River. Along the Jeneberang River flow, be found a rice fields area, mining and resident settlements which causes the entry of organic matter into river flow bodies. The purpose of this study was to determine the level of eurofication that occurred in the Jeneberang River and also to determine the effect of eutrophication on water quality in that river. This research was descriptive research using survey methods, this research was carried out by taking water samples at five stations namely, upstream, middle and downstream. The results showed that eutrophication had occurred in the Jenebrang River and was at the hypertrophic status. In addition, the results of the regression test showed that eutrophication had  a significant take effect on dissolved oxygen content and Ph on the Jeneberang river. However, eutrophication does no significant effect on abundance  plankton, and temperature.

Abstract

Penelitian ini adalah penelitian eksperimen yang bertujuan untuk mengetahui pengaruh perlakuan metode pemijahan yang berbeda terhadap pembuahan dan penetesan pemijahan pada ikan mas, dan untuk mengetahui metode perlakauan terbaik dalam pemijahan ikan mas pada menggunakan perlakuan metode yang berbeda terhadap pebuahan dan daya tetas telur ikan mas. Variabel Bebas  (Independent Variable), dalam penelitian ini adalah pemijahan dengan metode alami, semi buatan dan buatan. Variabel terikat (Dependent Variable), dalam penelitian adalah jumlah telur terbuahi dan jumlah telur menetas. Data hasil penelitian diperoleh dengan menggunakan metode sampling yang dilakukan mengambil perwakian telur dengan jumlah 300 dari jumlah keseluruhan telur yang di keluarkan pada setiap indukan Teknik analisis data yaitu dengan analisis ANOVA. Penggunaan metode pemijahan yang berbeda berpengaruh sangat nyata terhadap jumlah terbuahi dan jumlah menetas namun tidak berpengaruh nyata terhadap jumlah telur yang dihasilkan. Metode terbaik pada penggunaan metode pemijahan yang berbeda adalah metode pemijahan alami.

Abstract

This study aims to describe the profile of vegetation diversity in the mangrove ecosystem in Tamuku Village, Bone-Bone-Bone District, North Luwu Regency. This research is a qualitative research using survey methods. The data collection technique uses the Quadrant Line Transect Survey technique. The data analysis technique uses the thinking flow which is divided into three stages, namely describing phenomena, classifying them, and seeing how the concepts that emerge are related to each other. The results of this study are the profile of mangrove vegetation in Tamuku Village, which is still found 16 varieties of true mangrove vegetation and 7 varieties of mangrove vegetation joined in the coastal area of Tamuku Village, Bone-Bone District, North Luwu Regency, South Sulawesi. The condition of mangrove vegetation in Tamuku Village is currently very worrying due to human activities that cause damage such as the project of normalization of flow, opening of new farms, disposal of garbage, water pollution due to chemicals, and exploitation of mangrove forests for living needs. The impact is ecosystem damage and reduced vegetation area as a place to grow and develop mangroves.
