Abstract

Rawa Pening Lake was be appointed as one of 15 National Priority Lakes (NPD) in Indonesia based on Presidential Regulation (Perpres) Number 60 of 2021, so a revitalization program was carried out in the lake. This study aims to determine the effect of revitalization on the population of Hydrilla verticillata in Lake Rawa Pening by comparing distribution data from observations in 2007. The distribution of Hydrilla verticillata was observed directly and the coordinates of its location were determined using the Global Positioning System (GPS) to determine distribution map compilation. using ArcMap Software version 10.1. The results showed that the population area of Hydrilla verticillata in Lake Rawa Pening was 0.029567 km2 or 0.11% of the total area of Lake Rawa Pening and was spread over six locations. There has been a decrease in the population area of Hydrilla verticillata by 1.65 km2 compared to observations in 2007 which is thought to have occurred due to a decrease in nitrogen and phosphate levels due to revitalization activities carried out after the establishment of Lake Rawa Pening as DPN.

Abstract

It is thought that the development of the Senjoyo River as a tourist attraction in Semarang Regency will cause changes to the natural ecosystem in the area, one of which is changing the structure of the existing gastropod community. This research is a quantitative analysis research using a survey method that aims to examine the structure of the gastropod community after the development of tourism activities on the Senjoyo River. Gastropod samples were taken from 10 different observation stations along the Senjoyo River, which are located at 7˚22'23"S and 110˚31'37"E. Observation station locations were determined by the purposive random sampling method, based on tourism activity density. The result showed types of gastropods that were found in the Senjoyo River namely, Sulcospira testudinaria, Tarebia granifera, Brotia costula, Thiara scraba, and Melanoides tuberculata with clustered distribution patterns (Id>1). Statistical analysis showed that location affected gastropod abundance (Asymp. Sig of 0.043), with the highest abundance found at station seven (45,11 individuals/m2). So station seven, with sandy and muddy substrate conditions, moderate current speed (0.257 m/s), and rarely found human activity, is the most suitable location to support the survival of gastropods in the Senjoyo River. Furthermore, the gastropod community structure indicates environmental changes at observation stations nine and ten, the locations where the most activities and construction of tourism facilities were found. That was indicated by the low diversity (H’= 0.00-0.01) and evenness (E = 0.00) index of gastropods, and there is dominance by Sulcospira testudinaria (C= 0.98-1.00).

Abstract

Kadmium merupakan salah satu logam berat yang bersifat toksik dan dapat diserap oleh tumbuhan. Tagetes erecta merupakan tanaman hias yang memiliki kemampuan toleransi yang tinggi terhadap cekaman logam berat, sehingga tanaman ini dapat digunakan sebagai agen fitoremediasi. Tujuan dari penelitian ini adalah untuk mengetahui efek dari cekaman logam berat pada proses perkecambahan dan pertumbuhan benih T. erecta pada media pupuk cair yang mangandung Cd. Penelitian dilakukan secara eksperimental menggunakan desain rancangan acak lengkap. Konsentrasi CdCl2 yang digunakan sebagai perlakuan antara lain 0 (kontrol), 25, 50, 100, dan 200ppm. Biji T. erecta dikecambahkan di dalam cawan petri yang dialasi dengan kertas merang dan ditutup dengan plastik berwarna gelap. Perkecambahan dilakukan di laboratorium. Parameter jumlah biji yang berkecambah diamati setiap hari selama 14 hari digunakan sebagai penentuan persentase perkecambahan dan indeks vigor kecambah. Pertumbuhan kecambah diamati pada parameter panjang radikula dan panjang hipokotil pada akhir penelitian. Pemberian perlakuan kadmium mempengaruhi secara nyata perkecambahan dan pertumbuhan kecambah T. erecta. Kadmium pada konsentrasi 100-200 ppm menghambat secara nyata perkecambahan dan pertumbuhan kecambah T. erecta. Pertumbuhan radikula T. erecta pada perlakuan Cd sebesar 25ppm menunjukkan ukuran yang lebih panjang dibanding perlakuan kontrol. Hal ini dikarenakan penambahan kadmium pada konsentrasi rendah sebesar 25ppm masih mampu ditoleransi dan merangsang pertumbuhan kecambah T. erecta. Cadmium is one of the heavy metals that is toxic and can be absorbed by plants. Tagetes erecta is an ornamental plant that has a high tolerance to heavy metal stress, so this plant can be used as a phytoremediation agent.  The purpose of this study was to determine the effects of heavy metal stress on the process of germination and growth of T. erecta seeds in liquid fertilizer media containing Cd. The research was conducted experimentally using a completely randomized design. The concentration of CdCl2 used as treatment included 0 (control), 25, 50, 100, and 200ppm. T. erecta seeds were germinated in a petri dish covered with straw paper and covered with dark colored plastic. Germination was carried out in the laboratory. The number of germinated seeds observed daily for 14 days was used to determine the germination percentage and vigor index of the sprouts. Sprout growth was observed in the parameters of radicle length and hypocotyl length at the end of the study. Cadmium treatment significantly affected the germination and growth of T. erecta sprouts. Cadmium at concentrations of 100-200 ppm significantly inhibited the germination and growth of T. erecta sprouts. Radicle growth of T. erecta in the Cd treatment of 25 ppm showed a longer size than the control treatment. This is because the addition of cadmium at a low concentration of 25 ppm can still be tolerated and stimulate the growth of T. erecta sprouts.
