Abstract

Sand mining in the village of Sp Padang is carried out in an open pit mining model through several processes, for example the washing process which is carried out to separate sand from other components.When the sludge in the form of mud and fine sand enters the river, this part causes the quality of river water around the sand mining location to decline. The purpose of this research was to determine the condition of water quality due to sand mining in the river Sp.Padang.The type of data collected is primary data. The research was conducted at 3 stations on the river Sp.Padang.The physico-chemical parameters of river water are used, namely: turbidity, temperature, pH, TSS, DO, BOD, COD, water discharge and current velocity. The data obtained from the laboratory were then analyzed, then comparisons were made with the Storet method.Sampling for water quality replaces the surrounding area with direct measurements and measurements made in the laboratory.The use of the Storet method refers to PP No. 82 of 2001. The principle of Storet is to integrate river water quality data with river water standards and then adjust it according to its use, by classifying water quality into four classes. The results of the data analysis of the quality of river water in Sp.Padang as a result of the sand mining activities are categorized as good class B (lightly polluted) with a score of -6. Sand mining activity affects the water quality of the Sirah River in Padang Island, OKI Regency.Key words : OKI, sand miners, storet method, water quality

Abstract

Catfish is classified as an omnivorous fish and has fast growth, has the ability to tolerate wide-ranging environmental parameters. The study aims to determine the length  growth, weight growth, survival rate, feed efficiency and to determine the water duality in the Catfish (Clarias sp.) juvenile pond with differend feed treatments. The results of research showed that different feeding had an effect on the growth of catfish (Clarias sp.) juveniles. Length growth ranged from 9.78-10.8 cm, the highest value was in treatment 3, namely 10.8 cm and the lowest was in treatment 1, namely 9.78 cm. Weight growth ranged from 24-39 g, the highest value was in treatment 3, namely 39g and the lowest was in treatment 1, namely 24g. The survival rate ranged from 0.95-1%, the highest value was in treatment 3, namely 1% and the lowest was in treatment 1, namely 0.95%. feed efficiency ranged from 2.124-3.55%, the hinghest value was found in treatment 3, namely 3.55% and the lowest in treatment 1, namely 2.124%. the water quality during the research was still in the appropriate range for growth and survival of catfish (Clarias sp.) juveniles.

Abstract

Tawes (Barbodes javanicus) termasuk dominan dan mempunyai nilai ekonomi. Penelitian dilakukan dari bulan Maret sampai April tahun 2022. Analisis di laboratorium perikanan Universitas Islam Ogan Komering Ilir Kayuagung. Analisis data mencakup panjang berat, indeks dan tingkat Dari hasil penelitian, ikan tawes memiliki bobot tubuh sebesar 147 gram, dari 39 ikan tawes yang diamati, bobot ikan terbesar yaitu 460 gram dan bobot ikan tawes terkecil adalah 70 gram. Rasio kelamin ikan tawes jantan lebih mendominasi dari ikan tawes betina. ikan tawes menghasilkan nilai b = 3.3229 , memiliki pola pertumbuhan allometrik positif. Ikan tawes betina memiliki tingkat gonad yaitu pulih salin. Indeks kematangan gonad (IKG) yang dihasilkan sebesar 2,03 %. Data ikan tawes indeks preponderan kelompok fitoplankton yaitu sebesar 75,5%, zooplankton sebesar 9,97%, bagian hewan sebesar 4,24% dan detritus sebesar 10,24%. Ikan tawes ini memiliki kebiasaan makan dengan menjadikan beberapa jenis dari fitoplankton sebagai pakan utama dan beberapa jenis dari zooplankton dan detritus sebagai kelompok pakan pelengkap
