Analisis functional feeding group pada makrozoobentos di Situ Gunung Putri, Kabupaten Bogor, Jawa Barat

Introduction

Analisis functional feeding group pada makrozoobentos di situ gunung putri, kabupaten bogor, jawa barat. Analisis Functional Feeding Group (FFG) makrozoobentos di Situ Gunung Putri, Bogor, Jawa Barat. Temukan 22 spesies (scrapers dominan). Pahami korelasi FFG dengan parameter perairan untuk bioasesmen ekosistem.

Abstract

Makrozoobentos merupakan biota yang berperan dalam fungsi ekosistem perairan dan umumnya digunakan dalam bioasesmen. Peranan dari makrozoobentos dalam fungsi ekosistem perairan dapat diketahui dengan menggunakan analisis Functional Feeding Group (FFG). Penelitian ini bertujuan untuk menganalisis Functional Feeding Group pada makrozoobentos di Situ Gunung Putri, Kabupaten Bogor, Jawa Barat. Penelitian dilakukan pada bulan Maret-April 2019 di lima stasiun meliputi inlet dari kawasan industri dan pemukiman, midlet, kawasan pertanian, dan outlet. Pengambilan sampel makrozoobentos dilakukan dengan menggunakan Ekman grab sebanyak tiga kali dikompositkan. Selain itu, dilakukan pula pengukuran parameter fisik kimiawi perairan dan substrat dasar. Berdasarkan hasil penelitian, secara keseluruhan ditemukan 22 spesies makrozoobentos yang tergolong ke dalam tiga kelompok FFG meliputi scrapers, collector gatherer, dan collector filterers. Kelompok scrapers memiliki kelimpahan tertinggi di semua stasiun pengamatan, diikuti kelompok collector gatherers dan collector filterers. Hasil analisis korelasi Spearman menunjukkan bahwa kelompok collector gatherers memiliki korelasi yang sangat kuat dengan parameter kedalaman perairan, turbiditas, dan oksigen terlarut (r > 0,7).

Review

This study provides a valuable analysis of the Functional Feeding Group (FFG) composition of macrozoobenthos in Situ Gunung Putri, highlighting a crucial aspect of aquatic ecosystem function and bioassessment. The clearly stated objective to analyze FFG distribution within this specific West Java lake, coupled with a well-defined methodology encompassing sampling across five distinct stations – ranging from industrial/residential inlets to agricultural zones and outlets – demonstrates a systematic approach. The inclusion of physico-chemical parameter measurements alongside macrozoobenthos sampling further enhances the potential for ecological interpretation. The research identified 22 macrozoobenthos species, categorized into three FFGs: scrapers, collector gatherers, and collector filterers. A key finding is the consistent dominance of the scrapers across all sampling stations, followed by collector gatherers and then collector filterers, indicating a particular trophic structure within the lake. Moreover, the study reveals a highly significant correlation (r > 0.7) between collector gatherers and several environmental parameters, specifically water depth, turbidity, and dissolved oxygen. This strong statistical relationship points towards specific environmental drivers influencing the distribution and abundance of this particular FFG. While the study successfully identifies the prominent FFGs and significant environmental correlations, a more in-depth discussion on the ecological implications of these findings would greatly enrich its contribution. For instance, exploring what the widespread dominance of scrapers suggests about the primary productivity, substrate stability, and overall trophic state of Situ Gunung Putri could provide valuable ecological context. Similarly, expanding on the potential causal mechanisms linking water depth, turbidity, and dissolved oxygen to the collector gatherer community, perhaps in relation to the specific conditions at each sampling station, would offer a clearer understanding of the lake's ecological health under varying anthropogenic influences. This research provides a strong baseline for future studies focusing on ecosystem health and management strategies for this important water body.
